How to choose a standard mold base for an injection mold factory to reduce processing time

As the saying goes, "details make or break". Especially in our work and study, due to the neglect of some details, our learning efficiency and work efficiency will not be improved. If we can pay attention to the details, there may be no detours in many things, and the same is true for the design and manufacture of custom automotive mould.

The design and manufacture of automobile molds is a process that requires careful planning. There will be some problems in the process of design, processing and production, such as the design of mold structure, the problem of mold layout, the selection of steel materials, the shrinkage of plastic materials or post-processing. Process related questions need to be answered. Generally faced with these problems, what an automotive mold design and manufacturing company has to do is to record every detail in detail.

A lot of costs have been invested in the design and manufacture of automobile molds, and manufacturers hope that they can get a satisfactory result after paying the relevant costs. Many manufacturers are afraid that the products produced by the design and manufacture of automobile molds cannot meet their own requirements. Therefore, before the mold design and processing, they need to deal with the actual needs and costs of customers. That is, we should pay attention to the details, so that customers can receive more satisfactory products.

How to choose a standard mold base for an injection mold factory to reduce processing time
Injection molds are customized for different plastic products, but there are many similarities in the structure of injection molds. Therefore, in order to manufacture molds more efficiently, injection mold processing plants have begun to use some standard mold bases. In custom mold opening, injection mold processing plants Different plastic products can be injected only by manufacturing different molding parts, which greatly reduces the processing time of injection molds. So what problems should the injection mold processing factory pay attention to when choosing a standard mold base?

1. The thickness of the mold base and the closing distance of the injection molding machine are different for different models and specifications of the injection molding machine, and the closing distance of the clamping mechanism of different structural forms is also different.

2. The relationship between the opening stroke of the injection mold and the distance between the front and rear dies and the stroke required to eject the part must be clear in the design. The ejection stroke should be greater than the distance between the front and rear dies required to take out the plastic part, and the ejection plastic The distance required for the parts should be less than the rated ejection stroke of the ejector hydraulic cylinder of the injection molding machine.

3. The Plastic Injection Molding Manufacturer should pay attention to the following matters when installing the standard mold base:

1) The dimensions of the standard mold base should not be affected by the spacing of the tie rods of the injection machine;

2) The positioning aperture and the positioning ring size should be well matched;

3) Whether the position of the ejection mechanism of the injection machine and the stroke of the ejector rod are appropriate;

4) Whether the nozzle aperture and spherical radius match the casting sleeve aperture and spherical groove size of the mold;

5) The position and diameter of the mold base mounting holes should match the corresponding screw holes on the moving template and fixed template of the injection molding machine.

4. When choosing a mold base for an injection mold processing factory, it is necessary to understand the technical requirements of plastic parts and their injection molding process to ensure the performance and reliability of plastic parts and injection molds. The strength and stiffness are checked and calculated to ensure that the dimensions of the front and rear molds and support plates meet the needs of the mold structure.
