Part of it.
According to the existing production technology and procedures to produce metal insert plastic products, not only the procedures are numerous, but the types of molds used are many. Many procedures require manual operation and cannot be continuously produced. The labor is large, the labor intensity of the workers is high, and the space occupied is also high. Larger; the production speed is low, the cycle is long, and the product quality is poor; in addition, the product quality stability and consistency are difficult to control, resulting in low production efficiency and high cost.
Summary of the invention
In order to solve the complicated manual procedures in the production of metal inserts and plastic products, the number and types of molds and machines used are various, and the manual use is large, the labor intensity is high, the space is large, the production speed is low, the cycle is long, and the product quality is poor. The quality stability and consistency of the products are difficult to control, low efficiency, and high cost; especially to solve the problems of bending, injection molding, cutting products, removing waste plastics and shearing scrap metal remnants, multiple different processes, In the prior art, the process is independently produced before and after, and cannot be connected to form an automated production. The present invention proposes the following technical solutions.
1. A method for producing plastic products with metal inserts in automotive sensors, including a pre-process, a continuous production process, and a waste treatment process. The pre-process is to punch a metal strip into flat metal parts, The position of the material frame is punched into a position hole, and the adhesion between the flat metal parts and the metal remaining material frame appears as a metal part material strip. The continuous production process, using a composite mold for processing, includes the following continuous automated steps,
The first step is to transport the metal parts material belt in the feeding work area at the left end of the composite mold; the conveying refers to let the push claw enter the positioning hole of the metal residual material frame, and the push claw advances to the right
When pushing the metal residual material frame to the right along with the flat metal parts; at least one place of the metal residual material frame is walking on the track on the way to the right;
The second step is to perform bending, injection molding, and cutting in sequence in the continuous production work area of the composite mold; the bending is bending and forming of flat metal parts, and the injection molding is bending and forming
The metal parts are used as inserts for injection packaging, and the cutting is to cut off the adhesion points, so that the product and the metal residual material frame are separated and the product falls freely.
2. The composite mold at least includes a feeding mechanism and an injection mold arranged from left to right; the feeding mechanism constitutes a feeding work area;
The injection mold constitutes a continuous production work area, that is, the bending, injection, and cutting operations are performed in the injection mold; the injection mold includes an upper mold and a lower mold;
The bending is to add an insert at the left end of the injection mold and bend accordingly; the cutting is to add an insert at the right end of the injection mold and cut with it.
3. The bending of flat metal parts is formed by bending more than once.
4. The bending of flat metal parts is the second bending forming, the first time is preliminary bending, and the second time is forming bending.
5. The said pre-process, while punching the metal strip into flat-shaped metal parts, punching a positioning hole on the metal residual material frame.
6. The adhesion between the flat metal parts and the metal residual material frame means that each flat metal part and the metal residual material frame have four adhesion points.
7. The continuous production process and the waste treatment process are closely linked automated production steps, that is, after the second step, the following waste treatment process steps are carried out. The third step is on the left side of the waste treatment work area. The fourth step is to cut the metal residual material frame at the right part of the waste processing work area; the cutting metal residual material frame is to cut the metal residual material frame into small pieces; The waste processing work area is located on the right side of the continuous production work area; the composite mold includes a waste processing work area in addition to the feeding work area and the continuous production work area.
8. In the injection molding process, positioning pins are used to penetrate the positioning holes of the metal residual material frame during the process of closing the injection mold, so as to achieve the accurate position of the metal parts.
9. The conveying of the metal parts material belt is carried out in a restricted state, that is, more than one restriction device is installed in the feeding work area, and its function is to not only allow the metal parts material belt to pass, but also to the metal parts material belt. The swing up and down inside and outside is restricted.
The beneficial effect of the present invention is to simplify the production process, greatly reduce the number and types of molds and machines used, reduce the labor intensity of workers, reduce production sites and production cycles, and effectively control the stability and consistency of product quality. Improve production efficiency and reduce costs; it is especially important to be able to solve bending, injection molding, cutting products, removing waste plastics, and cutting scrap metal residual materials, multiple different types of work, processes before and after, eliminating manual procedures, forming Continuous automated production.

Production method of metal insert plastic product in automobile sensor

First of all, it should be noted that, to implement the method of the present invention, a vertical injection molding machine is required. If a horizontal injection molding machine is used, the method of the present invention cannot be directly implemented.
In order to implement the method of the present invention, in terms of hardware, in addition to the use of a vertical injection molding machine, it is also necessary to provide a matching gas circuit, a circuit including a control circuit, and to carry out mechanical innovation or transformation.
For vertical injection molding machines, ordinary injection molds, gas circuits, circuits, including control circuits, etc., these are all existing very mature technical content and will not be described in this manual. The method of the present invention and the composite mold that must be used when implementing the method of the present invention, especially those involving innovative content, will be mainly introduced and described below.
Metal inserts and plastic products are used in automotive sensors and are used and produced in large quantities. Figure
In the prior art, the frames for bending, injection molding, cutting products, removing waste plastics, and cutting scrap metal are produced by independent machines and manual assistance, and cannot be integrated into automated production. To form a one-stop continuous production, the difficulty lies in the production of metal insert plastic products, not only involves multiple different types of work or procedures, but also involves the coordination and connection between different types of molds and machines.
For the above situation, if the method of the present invention is used for production, the beneficial effects are: not only the production process is simplified, the number and types of molds and machines used are greatly reduced, but the labor intensity of workers can be reduced, and the production site and production site can be reduced. The production cycle can effectively control the stability and consistency of product quality, improve production efficiency and reduce costs; in addition, more importantly, it can also solve the problem of coordination and connection between different types of molds and machines.
