Improved runner system of automobile brake wire bracket

Abstract

The invention relates to an improved runner system of an automobile brake wire bracket. The runner system is arranged outside the bottom connected with the planar end of a die-casting mold cavity of the automobile brake wire bracket and is located outside the side away from plastic clip mounting grooves to be die-cast; the runner system comprises a straight runner and a transverse runner connectedwith the tail end of the straight runner; a sprue part communicating with the die-casting mold cavity is arranged at the tail end of the transverse runner; the transverse runner is of a curved runnerstructure; an included angle is formed between the transverse runner and the sprue part. According to the runner system, the positions and the shapes of the runners are changed, so that the erosion of metal liquid to the casting mold cavity is reduced; the size of mounting holes under the plastic clip mounting grooves is ensured; the service life of a mold is also prolonged.

Description

technical field [0001] The invention belongs to the technical field of casting of automobile cable brackets, relates to the runner technology of die-casting molds of automobile cable brackets, and in particular relates to an improved runner system of automobile cable brackets. Background technique [0002] The car cable bracket is a cast aluminum part used to fix and support the car brake line. There are two plastic card installation slots on the car cable bracket, and a square installation hole is provided under each installation slot for inserting a plastic card. positioning column. After the plastic card is installed in the installation groove, a threading pipe is arranged on the plastic card, and the brake line passes through the threading pipe. [0003] The die-casting mold of existing automobile cable support (referring to image 3 with 4 ) runner system 3 is arranged on the outside of the plane end of the die-casting cavity 1, and the flow direction of the molten me...

AI Technical Summary

Problems solved by technology

[0003] The die-casting mold of existing automobile cable support (seeing image 3 and 4 ) runner system 3 is arranged on the outside of the plane end of the die-casting cavity 1, and the flow direction of the molten metal at the end of the runner system is parallel to the side where the plastic card mounting groove 1-3 to be formed near the plane end is located. During the die-casting process, the lower mounting holes 1-4 corresponding to the mounting grooves were severely eroded, resulting in serious changes in the size of the mounting holes, which could not meet the requirements for later installation of plastic cards. In addition, the service life of the mold was also reduced.
