Injection molding production line and injection molding process of ABS watch shell

Abstract

The invention discloses an injection molding production line and injection molding process of an ABS watch shell, and belongs to the field of ABS injection molding. According to the technical scheme,the molding production line and injection molding process is characterized by comprising a drying oven, an injection molding machine and an annealing device. The injection molding process comprises the following steps that firstly, ABS plastic raw materials are put into the drying oven to be dried, meanwhile, the injection molding machine and an injection mold are pre-heated, then the raw materials are placed in a screw barrel of the injection molding machine, the injection molding machine is used for heating the raw materials to be in a molten state, the raw materials are injected into the injection mold to be formed into finished products, the injection mold is cooled, then opening the mold is conducted, an ejection mechanism ejects the finished products out of the male mold so as to make the finished products fall into a water slide way of the annealing device, and the finished products pass through the water slide way and slide to a hot water tank for annealing and are conveyed toa collecting box through a conveying belt. According to the injection molding process, the problems that the ABS watch shell is not convenient to anneal after being just subjected to injection moldingand annealing time is not good to control are solved, so that the effects that the ABS watch shell can be automatically annealed after being just subjected to the injection molding and the annealingtime can be accurately controlled when the ABS watch shell is transported through the conveying belt is achieved.

Description

technical field [0001] The invention relates to the field of ABS injection molding, in particular to an injection molding production line and an injection molding process for an ABS watch case. Background technique [0002] ABS plastic is a terpolymer of acrylonitrile (A), butadiene (B) and styrene (S). The relative content of the three monomers can be changed arbitrarily to make various resins. ABS plastic has excellent mechanical properties of toughness, hardness, rigid phase balance, good comprehensive performance, high impact strength, chemical stability, and good electrical properties. It is suitable for general injection molding parts, and after injection molding, it can also solve the problem of stress concentration through annealing process, so that the shape of ABS plastic injection molding parts can be more stable, standard and of higher quality. [0003] like figure 1 and figure 2 As shown, now it is necessary to process a watch casing, including a casing 1, a...

AI Technical Summary

Problems solved by technology

[0010] Annealing the watch case with the above-mentioned annealing device not only needs to manually move the injection-molded finished products into the annealing device, but also can only anneal one batch of finished products at a time. Since the annealing time of ABS plastic is relatively long, the production efficiency of the injection molding machine is relatively high. Therefore, the annealing efficiency of the above-mentioned annealing device is lower than that of the injection molding machine, and cannot be adapted to the injection molding machine.
