An automobile bracket with an insert and a die-casting mold for forming the bracket

Abstract

The invention discloses an automobile bracket with an insert and a die-casting mold for forming the automobile bracket, comprising: a body, an installation cavity is arranged on the upper part of the body, and two brackets are formed on the side of the body; and a through hole is opened on the side of the body, through which The hole is between the two brackets, and the through hole communicates with the installation cavity; the insert is arranged in the through hole and is on the side close to the installation cavity; the insert is provided with a positioning surface. Its die-casting mold includes: fixed mold assembly, moving mold assembly, core pulling assembly includes front, rear, left and right sliders, front, rear, left and right sliders and the first cavity and the second cavity Form the mold cavity for forming the car bracket; the left slider is provided with an insert pin, one end of the insert pin extends into the mold cavity, and an insert is set on the insert pin, when the car bracket is formed, the insert and the car The brackets are connected as a whole; casting components, ejecting components, and supporting components. The invention has the advantages that the automobile bracket product has low porosity and reasonable mold structure layout.

Description

technical field [0001] The invention relates to the technical field of die-casting molds, in particular to an automobile bracket with inserts and a die-casting mold for forming the bracket. Background technique [0002] The assembly of automobile brackets with transmission shafts and other parts requires strong load-bearing capacity and good sealing performance of the brackets, so as to meet the use requirements of the brackets. The production capacity requirements of the brackets are large, and most brackets are formed by die-casting molds. Existing The problems existing in the molding of the bracket are: it is difficult to release the mold at the through hole of the bracket, and there are many air holes on the circumference of the through hole. After the through hole of the formed bracket is processed, the internal air holes are exposed. After the through hole is inserted, problems such as oil leakage and gaps will occur, so the customer's requirements cannot be met, and t...

Problems solved by technology

[0002] The assembly of automobile brackets with transmission shafts and other parts requires strong load-bearing capacity and good sealing performance of the brackets, so as to meet the use requirements of the brackets. The production capacity requirements of the brackets are large, and most brackets are formed by die-casting molds. Existing The problems existing in the molding of the bracket are: it is difficult to release the mold at the through hole of the bracket, and there are many air holes on the circumference of the through hole. After the through hole of the formed bracket is processed, the internal air holes are exposed. After the through hole is inserted, there will be problems such as oil leakage and gaps, so it cannot meet customer requirements, and the scrap rate of the bracket is high

And when die casting is used, the bottom surface of the bracket is the end of the molten metal flow, which is easy to wrap the gas collected from the front of the cavity to the bottom surface of the bracket. Similarly, when the bottom surface of the bracket is processed, the air holes on the bottom surface are exposed, which cannot meet the requirements Shelf tightness requirements

[0003] In order to solve the above-mentioned problems existing in existing die-casting molds, it is necessary to design a bracket with simple mold release, and a die-casting mold that ensures low porosity after the bracket is formed.
