Embodiment Construction

[0016] As shown in the figure, it is the die-casting mold for the upper shell of the automobile engine and the second-stage core-pulling. The point of this model is: for products with bosses and inner holes on the outer wall of metal die-casting parts, if we use existing molds for these products It is very difficult to complete the core-pulling of the boss on the side wall of the product and the inner hole after molding. If the existing technology is used to complete the core-pulling, the product will be pulled or broken from the outer boss. The core pulling is done manually, the production efficiency is extremely low, and the safety of workers cannot be guaranteed. In order to achieve the purpose of mobile demoulding of products, I combine years of experience in mold design, and specially adopt the delayed core-pulling principle of sliders and inclined guide pillars; the mechanism of sliders is installed in the mold sliders to complete this difficult core-pulling action. . T...

Abstract

A die-casting die for automobile engine upper shell installation and secondary core pulling is composed of a movable die seat plate, a fixed die plate, a movable die plate, a movable die base plate, screws, an inclined guide column, a positioning ball, a spring, a push plate, a pull rod, a mold core, a large sliding block, a small sliding block, a check block and a safety component. A fixed die seat plate (1) and the fixed die plate (2) are connected in a fastened mode through the first screw (20). The safety component (18) and the first spring (19) are installed in a stepped hole in the fixed die plate (2). The inclined guide column (8) is installed in an inclined hole in the fixed die plate (2). The inclined guide column (8) and the small sliding block (15) are in sliding fit. The small sliding block (15) and the large sliding block (14) are in sliding clearance fit. The movable die plate (3) and the mold core (13) are in clearance fit. The pull rod (12) is installed on a push plate (11). The pull rod (12) is in sliding clearance fit with the movable die base plate (4) and the mold core (13). The movable die plate (3), the movable die base plate (4) and the movable die seat plate (5) are connected in a fastened mode through the second screw (16).

Description

technical field [0001] The invention relates to a metal die-casting molding die, which is a die-casting die for an upper shell of an automobile engine and a secondary core pulling. Background technique [0002] In the mold manufacturing industry, the core-pulling mechanism of the mold can be divided into several categories: manual, motorized, pneumatic or hydraulic. (1) Manual core-pulling mechanism, which relies on manual removal of the core and the product after the mold is opened, and separates the product from the workpiece outside the mold. It is simple in structure and convenient to manufacture, but the production efficiency is low and the labor intensity is high. At the same time, it is very dangerous for workers to operate the mold, and it is difficult to ensure the safety of workers. (2) Motorized core-pulling mechanism, which relies on the mold-opening force of the injection machine or die-casting machine to pull out the core through the transmission parts when op...
