A die-casting mold that prevents mold on product packs

Abstract

The invention discloses a die-casting die capable of preventing a product from wrapping an upper die. The die comprises an upper die and a lower die; a long groove which passes through the left side and the right side is formed in the upper die; a cross beam is arranged in the long groove; a back pulling rod extending into an upper die cavity, and guide columns which are glidingly connected to the upper side and the lower side of the long groove are arranged on the cross beam; the lower ends of the guide columns are clung to a parting surface; a cross beam pressing spring for propping the cross beam sleeves the upper end of each guide column; a first pull hook and a corresponding limiting structure are respectively arranged at the left side and the right side of the lower die by rotating; a first bulge is arranged at the lower end of the first pull hook, and a hooking part at the upper end of the first pull hook can hook the end part of the cross beam; a torsional spring is arranged on a rotating shaft of the first pull hook; a shifting rod is fixedly arranged beside the first pull hook of the upper die; a first push block is arranged at one side of the lower part of the shifting rod, close to the first bulge; guide inclined surfaces are arranged at two ends of the first push block. With the adoption of the die, all products can be stopped at the lower die during forming, so that the phenomenon of bending and deforming of the products after forming can be effectively avoided.

Description

technical field [0001] The invention relates to the technical field of molds, in particular to an aluminum alloy die-casting mold structure. Background technique [0002] Existing aluminum alloy die-casting molds usually include an upper mold, a lower mold, a pouring system arranged on the upper mold, an ejection mechanism arranged on the lower mold, and a cooling system, etc. As far as the product with cavity is concerned, in order to facilitate the ejection of the product after molding, a concave cavity is usually set on the upper mold, and a convex core is set on the lower mold. When the upper and lower molds are combined, the upper mold The cavity of the molded product is formed between the cavity body and the core of the lower mold. After the product is formed and cooled, the upper and lower molds are separated, and the product stays on the lower mold by the mold core force generated by its cooling shrinkage. Finally, the product is pushed along the mold through the ej...

AI Technical Summary

Problems solved by technology

[0003] One purpose of the present invention is to solve the problem that the existing aluminum alloy die-casting mold is prone to product package upper mold and bending deformation when forming products with openings on both sides of the upper and lower sides, and to provide a method that can ensure that all products stay in the lower mold during molding. Die-casting mold, so as to effectively avoid bending deformation of the formed product

[0004] Another object of the present invention is to solve the problem that the existing aluminum alloy die-casting molds are difficult to simultaneously form the lateral forming hole and the radial blind hole on the inner wall of the lateral forming hole, and to provide a secondary core-pulling device. Die-casting mold, which can simultaneously form the lateral forming hole and the radial blind hole on the inner wall of the lateral forming hole at one time, thereby avoiding subsequent secondary machining and improving production efficiency
