Problems solved by technology

[0002] Die-casting molds are widely used in the production process of auto parts, and many auto parts have a large number of surfaces and different angles, which brings a lot of inconvenience to the mold opening
For example, if the die-casting mold is used to produce the automobile rearview mirror tube frame made of magnesium alloy, the product's lateral, molded area and positive parting surface projected area reach 1:2:1, and the lateral clamping force reaches 4 tons. , the product will be broken in the side core pulling and cannot be produced, which puts forward very high requirements for the mold

Embodiment 1

[0024] Specific steps are as follows:

[0025] (a) if figure 1 As shown, the mold die-casting pouring and cooling are completed. At this time, the inner side of the lower end of the push plate locking block 6 withstands the left side of the thimble push plate 10, and then the movable mold 3 and the fixed mold are separated by the toggle mold opening and closing mechanism of the die-casting machine. 1. At the same time as the mold is opened, the oil cylinder 9 moves, and the slider 15 is pulled by the slider seat 14 to slide to the left on the friction block 12;

[0026] (b) if figure 2 As shown, the rising of the movable template 2 is carried out simultaneously with the action of the oil cylinder 9, and the inclined guide post 4 slides in the inclined guide hole 5. When the slider seat 14 slides to the limit block 13 and pushes against the thimble fixing plate 11, it cannot slide. , the thimble 17 has partially separated the workpiece 20 from the slider 15;

Abstract

The invention relates to a die-casting die and a method for delay ejection of lateral die sinking. The die-casting die comprises a movable die, a fixed die, a movable template and a fixed template, wherein the movable die is embedded and fixed at the lower end of the movable template; the fixed die is embedded and fixed at the upper end of the fixed template; a slide block is arranged at one side of the fixed die; a friction block is fixedly arranged on the fixed template at one side of the slide block; a slide block seat is arranged at the upper end of the friction block; the slide block seat is fixedly connected with the slide block; a thimble push plate is vertically arranged on the friction block at the left side of the slide block seat; a plurality of thimbles are horizontally arranged on a thimble fixing plate evenly; the thimbles rightwards pass through the slide block seat and the slide block and are communicated with a die cavity of the fixed die; a cylinder is arranged at the left side of the friction block; a push rod of the cylinder is connected with the right end of the slide block seat; an inclined guide post is arranged on the movable template, and a push plate lock block is fixedly arranged at the left lateral wall of the movable template. The die-casting die is simple in structure, reliable to operate, and simple to operate, and the quality of the product is ensured.

Description

technical field [0001] The invention relates to the field of die-casting molds, in particular to a die-casting mold and a method for lateral mold opening and ejection delay. Background technique [0002] Die-casting molds are widely used in the production process of auto parts, and many auto parts have a large number of surfaces and different angles, which brings a lot of inconvenience to the mold opening. For example, if the die-casting mold is used to produce the automobile rearview mirror tube frame made of magnesium alloy, the product's lateral, molded area and positive parting surface projected area reach 1:2:1, and the lateral clamping force reaches 4 tons. , The product will be broken in the side core pulling and cannot be produced, which puts forward very high requirements for the mold. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a die-casting mold and method for lateral mold opening and delayed ejec...
