Embodiment

[0040] A kind of injection molding production molding method of plastic parts, is characterized in that, comprises forming mold, comprises the following steps:

[0041] Injection molding: first pour the molten plastic from the feed hopper, and the plastic that enters the feed hopper continues to flow down, and then enters the first mold, the second mold, the third mold, and the fourth mold to correct the gaps in between. The gap is filled, and at the same time, the temperature control pipe will heat or cool the first mold and the second mold respectively according to the actual processing conditions, so as to form injection molded parts of a specific shape with uniform thickness;

[0042] Demoulding: Lift the top plate, and then pass the connecting column to lift the upper template and the lower template in turn, and the lower template is bounced under the action of the demoulding spring, so that the first mold and the second lower mold are withdrawn from the lower template, E...

Abstract

The invention provides a plastic part injection molding production forming method. A forming mold is included and comprises a top plate, an upper mold plate, a lower mold plate and a bottom plate which are sequentially arranged. A first mold groove is formed in the upper mold plate and internally provided with a first mold. A second mold groove is formed in the lower mold plate and internally provided with a second mold. The first mold and the second mold are correspondingly arranged. A third mold and a fourth mold are symmetrically arranged between the first mold and the second mold. The third mold is connected with a first side drive block, and the fourth mold is connected with a second side drive block. The first mold, the second mold, the third mold and the fourth mold are correspondingly arranged in a matched manner. According to the plastic part injection molding production forming method, automatic machining of injection molding inserts can be achieved, the produced injection molding inserts in specific shapes are uniform in thickness, the injection molding machining precision is high, the product yield is high, rapid demolding can be achieved, the production efficiency is high, the product meets the requirement of the industry standard, and the plastic part injection molding production forming method is suitable for large-scale automatic production.

Description

technical field [0001] The invention belongs to the technical field of injection molding processing devices, and in particular relates to an injection molding production molding method for plastic parts. Background technique [0002] The advantages of the injection molding method are fast production speed, high efficiency, automatic operation, various designs and colors, simple to complex shapes, large to small sizes, accurate product sizes, easy replacement of products, and complex shapes. Parts, injection molding is suitable for mass production and complex shape products and other molding processing fields. The injection molding process can be roughly divided into the following six stages: mold closing, injection, pressure holding, cooling, mold opening, and product removal. The above process is carried out repeatedly, and the products can be produced periodically in batches. [0003] In the prior art, there are many injection-molded products, among which plastic inserts...
