Automobile battery shell injection molding parts precision mold

Abstract

The invention discloses a precise mold of vehicle accumulator shell injection molding parts. The precise mold comprises a front mold and a back mold; a front mold core is fixed on an upper template; a back mold core is fixed on the upper template, and is opposite to the front mold core; the front mold core and the back mold core are closed to form a product mold cavity; a core pulling slide block is arranged at the side part of the mold cavity, and is embedded between the front mold core and the back mold core; slide blocks are arranged at two side parts of the back mold core; the core pulling slide block is connected to the slide blocks; the two slide blocks are guided to slide through two inclined guide columns relatively independently arranged; the inclined guide columns are fixed at two side parts of the front mold core, and the lower end parts are inserted in the slide blocks; the lower side of a runner is communicated with the mold cavity; and a return device is arranged between the back mold core and the slide blocks. The precise mold of the vehicle accumulator shell injection molding parts improves the product performance of the injection molding parts, is short in molding period and high in production efficiency, is low in wear of an accumulator mold by a flux, and can mold the injection molding parts with complex shapes, clear surface patterns and marks and high size precision in large batches.

Description

technical field [0001] The invention relates to a precision mold, in particular to a precision mold for an injection molded part of an automobile accumulator shell. Background technique [0002] A car battery is a device that converts chemical energy into electrical energy and is a DC power supply. The battery case needs to have the characteristics of corrosion resistance and high temperature resistance, so the mold for injection molding of the car battery case should have uniform and stable molding, long service life, high precision, simple production process, low energy consumption and high quality after molding. The precision of the product is high. Since the automobile battery case is an injection molded part with a large volume and many ribs, some special structures must be needed to solve the practical problems in the prior art that it is difficult to achieve uniform injection molding and non-destructive demoulding due to the many ribs in the product. The design simpl...

Problems solved by technology

The battery case needs to have the characteristics of corrosion resistance and high temperature resistance, so the mold for injection molding of the car battery case should have uniform and stable molding, long service life, high precision, simple production process, low energy consumption and high quality after molding. The precision of the product is high. Since the automobile battery case is an injection molded part with a large volume and many ribs, some special structures must be needed to solve the practical problems in the prior art that it is difficult to achieve uniform injection molding and non-destructive demoulding due to the many ribs in the product. The design simplifies the structure of the automobile battery shell mold, so that the parting surface of the product is simple, the hot melt material is evenly filled, and the demoulding is easy, which makes the design of the automobile battery shell mold more reasonable
