Problems solved by technology
Usually, the compression side of the compression mold (the side with the hydraulic cylinder) is located in the movable side mold, and the applicant encountered a technical difficulty when trying to set the compression side in the fixed side mold
The difficulty is that the molten plastic enters the mold cavity through the vertical flow channel through the horizontal flow channel
With the compression of the mold cavity, the length of the vertical flow channel (such as the distance from the inlet of the gate bushing to the horizontal flow channel) will be reduced, and the space of the vertical flow channel will be reduced after compression. It will cause the molten plastic in the flow channel to have nowhere to go, which will affect the clamping of the mold, and cause the pressure in the cavity to be unstable, affecting the quality of the finished product

Embodiment Construction
[0017] The aforementioned and other technical contents, features and effects of the present invention will be clearly presented in the following detailed description of a preferred embodiment with reference to the drawings. The directional terms mentioned in the following embodiments, such as: up, down, left, right, front or rear, etc., are used for illustration and not for limiting the present invention.
[0018] In one example of the present invention, the injection molding mold is a mold applicable to an injection molding machine, and the injection molding mold is divided into two parts, a fixed side and a movable side, according to its mobility during the manufacturing process. In the injection molding process, the fixed side is actually fixed on the fixed side plate of the injection molding machine, while the movable side is connected to the movable side plate of the injection molding machine, and the movement of the movable side is used to open, Clamping.

An injection molding die comprises a fixed side fixing plate, a first die plate, a first die core, a movable side fixing plate, a second die plate, a machine part, a sliding block and a second die core. The first mold plate is arranged in the first end direction of the fixed side fixing plate, the second mold plate is arranged in the first end direction of the first mold plate, and the movable side fixing plate is arranged in the first end direction of the second mold plate. The first mold core and the second mold core are arranged in the containing space of the first mold plate and the containing space of the second mold plate respectively, a mold cavity is defined by the first mold core and the second mold core during mold closing, and a runner is defined between the first mold plate andthe second mold plate and communicated with the mold cavity. A containing space is formed between the movable side fixing plate and the second mold plate so as to contain the machine part and the sliding block, the sliding block is located between the machine part and the runner, and when the machine part acts, the sliding block is in linkage with the machine part. A method of manufacturing the polymer material element is also provided.
Description
technical field [0001] The present invention relates to a mold, in particular to a mold for injection molding process and a method for manufacturing polymer material components. Background technique [0002] The process of using injection molding machines with molds to produce polymer material components, such as optical lenses, has a long history. In the mold, according to its fixed position, the mold can be split into a fixed side mold and a movable side mold. When the templates of the fixed side mold and the movable side mold touch and combine with each other, the mold is in a closed state. At this time, the plastic raw material is heated and melted by the injection molding machine and then injected into the mold, so that the plastic raw material is covered in the mold. In the cavity, after cooling, an optical element is made. [0003] In the conventional injection molding process, a compressible mold is used. Compressible molds can compress the space of the mold cavit...
