One-time injection molding die of multi-face irregular workpieces

Abstract

The invention discloses a one-time injection molding die of multi-face irregular workpieces. The one-time injection molding die comprises an upper die base and a lower die base, particularly, the lower die base is provided with a lower die central fixing die holder, four fixing die holders and four sliding die holders, each sliding die holder is arranged between every two fixing die holders, all the die holders are in a nine-grid pattern layout, and the top of each sliding die holder is provided with a guide groove hole; the upper die base is provided with an upper die central fixing die holder and four driving guide rods having fixed inclination, the driving guide rods are connected in the guide groove holes in a sliding mode, the four sliding die holders slide inwards to gather together or slide outwards to extend in die opening-closing switching processes of the upper die base and the lower die base. According to the injection molding die, the three-dimensional multi-fact die opening mode is adopted, and an injection molding cavity of the multi-face irregular workpieces is constituted by the surface of the upper die central fixing die holder, the surface of the lower die central fixing die holder, and the molded surfaces of the four sliding die holders. Meanwhile, the sliding die holders further have die retreating displacement, die retreating of the workpieces is facilitated, accuracy and production efficiency of finished products are improved, and cost is low.

Description

technical field [0001] The invention relates to an injection mold, in particular to a one-time injection molding mold for multi-face irregular workpieces. Background technique [0002] Injection mold is a tool for producing plastic products; it is also a tool for giving plastic products complete structure and precise dimensions. Injection molding is a processing method used in the mass production of certain complex-shaped parts. Specifically, it refers to injecting the heated and melted material into the mold cavity by high pressure, and after cooling and solidifying, a molded product is obtained. The injection mold consists of a moving mold and a fixed mold. The moving mold is installed on the movable template of the injection molding machine, and the fixed mold is installed on the fixed template of the injection molding machine. During injection molding, the movable mold and the fixed mold are closed to form the gating system and the cavity, and the movable mold and the ...

AI Technical Summary

Problems solved by technology

Based on the special structure of the above-mentioned workpieces, it is difficult to achieve injection molding of multi-faceted irregular workpieces only by clamping the upper and lower molds. Even if the mold core can be processed and implemented for injection molding production, it is basically impossible to eject the mold. Generally, injection molds are used. Rough mold processing of multi-faceted irregular workpieces, and then fine mold processing of the rough molds, the production process of such operations is cumbersome, the production efficiency is low, the cost is high, and defective products are prone to occur, and the pass rate is low
