Embodiment Construction

[0013] The present invention will be described in further detail below by means of specific embodiments:

[0014] The reference signs in the drawings of the description include: fixed mold frame 1, liquid inlet hole 2, fixed mold core 3, exhaust hole 4, exhaust groove 5, first screw 6, casting runner 7, movable mold frame 8, Moving mold core 9, second screw 10.

[0015] The embodiment is basically as attached figure 1 Shown: a hot chamber die-casting mold with an exhaust system, including a fixed mold frame 1, a liquid inlet hole 2 is opened in the middle of the fixed mold frame 1, an inner stop is opened on the left side of the fixed mold frame 1, and a fixed mold The left side of the frame 1 is also provided with a first groove, and a fixed mold core 3 is arranged in the first groove, and the fixed mold frame 1 and the fixed mold core 3 are connected by four first screws 6 uniformly distributed in the circumferential direction.

[0016] A movable mold core 9 is provided on...

Abstract

The invention discloses a hot chamber die-casting die with an exhaust system. The hot chamber die-casting die comprises a movable die frame and a fixed die frame. A movable die core is arranged at the position of the movable die frame. A fixed die core is arranged at the position of the fixed die frame. A casting runner is formed by the movable die core and the fixed die core during die assembly. A liquid inlet hole is formed in the fixed die frame. The liquid inlet hole communicates with the middle portion of the casting runner. Exhaust holes communicating with the casting runner are symmetrically formed in the two sides of the fixed die core with the liquid inlet hole as the center. Exhaust grooves are symmetrically formed in the two sides of the fixed die frame, and each exhaust groove communicates with the exhaust hole in the same side with the exhaust groove. According to the scheme, the fixed die core is provided with the exhaust holes, the exhaust holes are formed in the two sides of the casting runner, when die casting is conducted, air pushed towards the two sides of the casting runner by molten metal right passes through the exhaust holes to be exhausted, and therefore the problem that air in the casting runner cannot be exhausted in time, and consequently, air holes are generated in a die-casting fitting can be effectively solved.

Description

technical field [0001] The invention relates to a hot chamber die-casting mold, in particular to a hot chamber die-casting mold with an exhaust system. Background technique [0002] In the die casting forming process, the mold used to form the casting is called a die-casting mold, and the die-casting mold is generally composed of a moving mold and a fixed mold. [0003] The fixed mold is fixed on the fixed mold mounting plate of the die-casting machine. There is a sprue on the fixed mold that communicates with the nozzle or the pressure chamber. , when the movable mold and the fixed mold are closed, the mold cavity and the casting system will be formed. At this time, the liquid metal fills the mold cavity under high pressure; Casting rolls out. [0004] In the actual production process of the currently used die-casting molds, there is often a certain amount of air in the casting runner. Once the air cannot be discharged in time, pores will be formed in the die-casting part...
