Injection mold of micro-molded dumbbell product

Abstract

The invention discloses an injection mold of a micro-molded dumbbell product. The injection mold is simple in structure, and can realize flexible production and improve the quality of the product. The injection mold comprises a fixed mold, a movable mold, molding inserts and an insert, wherein a first guide hole, a pouring gate and a main runner communicated with the pouring gate are formed in the fixed mold; a mounting slot and a second guide hole are formed in the movable mold; the fixed mold is positioned above the movable mold; the movable mold and the fixed mold are guided by a guide column; a cavity for containing the dumbbell product is formed in the insert; a cold material well is arranged on the insert and is communicated with the cavity; the insert is mounted in the mounting slot; an outlet of the main runner in the fixed mold is positioned above the cold material well and is communicated with the cold material well; the molding inserts are mounted in the cavity and matched with the cavity; the upper surfaces of the molding inserts form the bottom surface of the cavity. The injection mold is high in production adaptability, and can realize flexible production, improve the working efficiency and lower the production cost.

Description

technical field [0001] The invention relates to a molding die for micro-molding products, in particular to an injection mold for micro-molding dumbbell-shaped products. Background technique [0002] Known: most of the existing tiny plastic products are produced by a compression molding machine, the production raw materials are pressed into a flat plate, and then cut according to the shape of the product on the flat plate to obtain the product. Using this method to produce micro-molded products will result in a large amount of material waste, heavy workload, low efficiency and high cost. [0003] With the development of science and technology, the appearance of micro-injection molding machines, in order to adapt to the production of micro-molded products, a new production method of micro-molded products, namely micro-molded technology, has emerged. Micro-molding technology includes two parts: micro-injection mold and micro-injection machine. The measurement of the dimension...

AI Technical Summary

Problems solved by technology

[0004] When micro-molded dumbbell-shaped products are produced by micro-molding technology, due to the complex shape of micro-molded dumbbell-shaped products, there is a phenomenon that the cavity is not filled, which seriously affects the quality of the product, resulting in a low yield of the product, and in When using traditional injection molds for production, a set of injection molds can only produce dumbbell-shaped injection molded parts of the same thickness

To produce products with different thicknesses, it is necessary to produce different injection molds. Because the cost of manufacturing injection molds is relatively high, the production cost is greatly increased; Single mode, low adaptability, poor production flexibility, low work efficiency, poor product quality, low yield and high production cost
