A hot runner system zinc alloy die-casting mold

Abstract

The invention discloses a zinc alloy die-casting mold for a hot runner system, which comprises a mold base, the mold base includes a sprue sleeve, a top plate, a backing plate, a cavity plate, a core plate, a cushion block and a bottom plate, and the side wall of the sprue sleeve is provided with The molten metal collection and reheating device, the side wall of the cavity plate is equipped with a casting heat recycling device, and the side wall of the core plate is equipped with a casting uniform flow device; the molten metal collection and reheating device includes the first opening and closing part installed on the upper surface of the top plate , the air pressure component set on the side wall of the backing plate, the heat conduction component set between the backing plate and the cavity plate, the negative pressure heating component set on the side wall of the cavity plate, and the second opening and closing set on the side wall of the cavity plate Components; the casting uniform flow device includes a temperature control component embedded in the core plate and a single-chip microcomputer set on the side wall of the core plate. The invention is a die-casting mold which can prevent the subsequent casting from being affected by the cooling of the metal liquid in the sprue sleeve, can avoid the waste of raw materials caused by a large amount of condensate at the casting gate, and is convenient for the metal liquid to evenly fill the mold cavity.

Description

technical field [0001] The invention mainly relates to the technical field of metal forming, in particular to a zinc alloy die-casting die of a hot runner system. Background technique [0002] Die casting is a metal casting process characterized by the use of a mold cavity to apply high pressure to molten metal in order to mold the metal into the desired shape. [0003] According to the hot runner system and zinc alloy forming die provided by the patent document with application number CN201920789552.3, it can be known that the product includes a manifold body, two hot nozzle bodies, a heating part, a temperature sensing part, and a runner structure; The flow channel structure includes a main flow channel and a branch flow channel, the branch flow channel includes a front section flow channel and a rear section flow channel, and the front section flow channel is a curved flow channel connecting the main flow channel and the rear section flow channel; the The rear-stage flow...

Problems solved by technology

[0004] The products in the above patents facilitate the smooth flow of molten metal in the flow channel into the cavity structure, reducing adverse phenomena such as molten metal backflow, but there is a possibility that the cooling of the molten metal in the sprue sleeve will affect subsequent casting, and the casting gate condensate The large amount causes waste of raw materials, and it is not convenient for the liquid metal to fill the cavity evenly
