Problems solved by technology

[0007] However, the valve assembly for ventilating the die-casting mold constructed as described above basically adopts the following structure, that is, the floating piston of the structure for detecting the inflow of the cast material and the ventilator participating in the vacuum generation process. The pistons interact with each other in a binary way, so its mechanism is very complicated
What's more, one side of the floating piston also needs to be equipped with another running piston to allow the venting piston to run smoothly, making its structure more complicated. In this case, these individual components cannot interact smoothly when used for a long time

Abstract

The present invention provides a unified valve assembly for ventilating a die casting mold. The unified valve assembly comprises: a casting block (1) with a penetrating hole formed at the center, an air discharge hole formed in the vertical direction in the penetrating hole, a casting flow path connected to the penetrating hole formed on one side, a cooling water flow path inside near the casting flow path; an operating block fixated and secured to the other side of the casting block; an operating valve formed by a guide bushing and an operating piston, wherein the guide bushing has an elastic means settled in the settling hole of the operating block, and one side of the operating piston contacts the elastic means and the other side is exposed to the casting flow path through the penetrating hole of the casting block; and a ventilating filter connected to the air discharge hole of the casting block.

Description

technical field [0001] The present invention relates to a valve assembly for the ventilation of a die casting mold. More specifically, the valve assembly with a unified structure for the ventilation of a die casting mold of the present invention combines a ventilation piston with a floating piston (floating piston) It is unified to make the discharge parts of the residual air inside the mold very simple, and the cooling water flow path formed inside the mass to be cast can greatly reduce the moving speed of the mass to be cast and prolong the ventilation time, thereby exhausting the residual air more completely , It also has a component that can directly detect the vacuum level inside the mold to perform more precise casting operations. Background technique [0002] When the molten cast material is injected into the molding space of the die-casting mold to make molded products of various shapes, if the air is not prevented from flowing into the molten cast material injected ...
