Die mold

Abstract

The invention relates to a die mold comprising an upper mold unit, a lower mold unit and a slide block unit, wherein the upper mold unit is provided with an upper mold cavity unit, and the lower mold unit is provided with a lower mold cavity unit; the upper mold cavity unit cooperates with the lower mold cavity unit; the slide block unit is arranged in the space formed by the cooperation of the upper mold cavity unit and the lower mold cavity unit; the bottom of the slide block unit is provided with a material inlet; the die mold also comprises an oil hydraulic slide block drawing device used for drawing out the slide block unit; and three side surfaces of the slide block unit are respectively provided with a unilateral angle of 2 degrees. The scheme of the invention comprises the tunnel-type material feeding structure on the bottom of the slide block unit of the die mold and the oil hydraulic slide block drawing device; the material inlet is arranged in the positions beneficial to filling and forming of the casting by utilizing the slide block unit; and gas in the space fills a lot of space obtaining the cavity by the substitution of the raw material, thereby overcoming many defects in form filling and die casting.

Description

technical field [0001] The invention relates to a die-casting die, in particular to a die-casting die for feeding material at the bottom of a slider, and belongs to the technical field of die-casting dies. Background technique [0002] Die casting belongs to the field of hot forming metal processing. The structural design of die casting molds has a great influence on die casting production, especially the correct setting and design of runners and gates directly affect the forming and quality of products. The design of the road not only improves the qualified rate of castings, reduces the return charge, but also prolongs the life of the mold. Today's die-casting products are becoming larger, more complex, and more precise, which puts forward higher requirements for the structural design of die-casting molds and the design of runners and gates. Sometimes it is often due to improper design of the mold structure and die-casting runners. As a result, the casting cannot be formed...

Problems solved by technology

Today's die-casting products are becoming larger, more complex, and more precise, which puts higher demands on the structural design of die-casting molds and the design of runners and gates. Sometimes it is often due to improper design of the mold structure and die-casting runners. As a result, the casting cannot be formed and the forming defect rate is extremely high. When it cannot be compensated by other die-casting parameters, it has to use the extreme die-casting conditions, die-casting technology and many other processing technologies to remove the adverse effects, which often increases a lot of manpower and labor. The physical effect is still unsatisfactory, the mold fails prematurely, and the cost of die castings increases
