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

Example Embodiment

[0013] Such as figure 1 The die casting mold shown in the prior art includes a set of upper mold units 1, a set of lower mold units 2, a set of upper mold cavity units 3 forming a cavity, and a set of lower mold cavity units 4 forming a cavity. The main components and other components omitted from the description constitute the structure and the combined space type, the space 6 for forming the die casting, the feed channel 7 and the feed port 8. During die-casting, the liquid raw material closes the inlet of the casting D part 9 to form a cavity space D part 9 where gas cannot be discharged. The small rib D part 9 can only be filled in the form of pressure flow, and the forming effect is not good.

[0014] Such as figure 2 The die-casting mold of the present invention shown includes a set of upper mold units 10, a set of lower mold units 20, a set of upper cavity units 30 forming a cavity, a set of lower cavity units 40 forming a cavity, and a set The slider unit 50, and the hyd...

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...
