Die-casting die and method for delay ejection of lateral die sinking

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...
