Abstract

The invention relates to the field of casting dies, and aims at providing a tubular automobile part casting die. The tubular automobile part casting die comprises an upper die body, a lower die body, a cavity defined by the upper die body and the lower die body, two main hole core-pulling devices provided with oppositely-arranged main hole cores, a through hole core-pulling device provided with a through hole core, three side hole core-pulling devices each provided with a side hole core, a casting system and an exhaust system. The cavity comprises a main tube cavity, a side tube cavity and an inclined tube cavity. The casting system comprises a plurality of main tube ingates communicated with the main tube cavity, an inclined tube ingate communicated with the inclined tube cavity, a connecting pouring gate and a main pouring gate arranged on the upper die body. The exhaust system comprises a plurality of exhaust channels and a plurality of air collecting cavities formed in the upper die body, one end of each exhaust channel is communicated with the cavity, and the other end of each exhaust channel is communicated with the side end of the lower die body. According to the tubular automobile part casting die, a cast tubular automobile part is not prone to deformation, mold filling is easy, and the tube hole die disengaging is easy.

Description

technical field [0001] The invention relates to the field of die-casting molds, in particular to a die-casting mold for tubular auto parts. Background technique [0002] as attached image 3 The illustrated tubular auto part 1 comprises a main pipe 12 having a main hole 11 with a super long aspect ratio, a side pipe 14 having three side holes 13 communicating with the main hole, diagonally cross-connected with the main pipe 12 and having a through hole 15 Inclined tube 16; traditional die-casting die-casting of the tubular auto parts has the disadvantages of difficulty in filling and easy deformation of the tube hole demoulding; therefore, it is easy to design a die-casting tubular auto part filling and easy demoulding of the tube holes Die-casting dies for tubular auto parts that are not easily deformed have become an urgent problem to be solved. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the existing die-ca...
