Temperature controllable semi-solid touch deforming mold

Abstract

The invention discloses a temperature controllable semi-solid touch deforming mold which comprises a split forming mold and a rectangular heat conduction block arranged on the outer wall of the forming mold in connection mode through bolts. A sprue communicated with a mold cavity is arranged on the top surface of the horizontal rectangular forming mold, at least two through holes used for heating tubes connected with external energy to be assembled into are arranged on the outer walls on two sides of the heat conduction block in the length direction, and at least one thermocouple is parallelly arranged between the heating tubes to form a heating temperature fixed point measurement structure. The temperature controllable semi-solid touch deforming mold is simple in external heating structure, accurate in temperature measuring, easy in temperature control and small in manufacture difficulty. A temperature field of the mold cavity of the forming mold is reasonably designed so that casting forming is benefited and mechanical property of cast products can reach the expected index.

Description

technical field [0001] The invention relates to a casting mold, in particular to a temperature-controllable semi-solid thixomorphism mold for aluminum alloy casting of a vehicle engine. Background technique [0002] Metal semi-solid forming technology is a modern advanced thermal processing technology, which is mainly used in the forming of important castings or high-strength castings. Thixotropy is the most widely used semi-solid forming process. The forming process of this process is simple, the forming quality is good, and the formed blank is easy to store and transport. However, the design of semi-solid thixotropic forming molds in the prior art is difficult. The temperature field in the mold cavity should be reasonably distributed according to the casting structure and metal type, and corresponding insulation measures should be taken. The accompanying problems are difficult mold structure design, temperature High control requirements, high production costs, and low pro...

Problems solved by technology

However, the design of semi-solid thixotropic forming molds in the prior art is difficult. The temperature field in the mold cavity should be reasonably distributed according to the casting structure and metal type, and corresponding insulation measures should be taken. The accompanying problems are difficult mold structure design, temperature High control requirements, high production costs, and low production efficiency, these series of practical problems seriously restrict the further application of metal semi-solid forming technology
