Description

TECHNICAL FIELD

[0001] The application relates to the technical field of casting forming molds, in particular to an automobile part casting forming mold. BACKGROUND

[0003] After the forming mold is opened, a mold release agent needs to be sprayed on the surface of the mold cavity, and when the mold release agent is sprayed, the automobile part is first taken out of the mold by a taking mechanical arm, and then another mechanical arm sprays, so that two mechanical arms need to work in sequence, and the efficiency bottleneck of the double mechanical arms leads to a prolonged production cycle and complicated operation.

DETAILED DESCRIPTION

[0043] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0044] In order to better understand the automobile parts casting forming die provided by the embodiment, the existing casting forming die is briefly introduced first. After the forming die is opened, the surface cavity of the die needs to be sprayed with a release agent. When spraying the release agent, the automobile parts are first taken out of the die by a taking mechanical arm, and then another mechanical arm sprays. Two mechanical arms need to work in sequence, which leads to low production efficiency and complex operation. At the same time, the release agent is sprayed on both dies when the die is opened. In order to improve the spraying range, multiple nozzles are used for double-sided spraying. The increase in the number of nozzles increases the required air pressure intensity, which requires a certain power of the pump body.

[0045] The specification aims to solve the above technical problems:

[0046] Embodiment one: refer to Figures 1-2 The first embodiment of the present application provides an automobile parts casting forming die, comprising:

[0047] The die casting die 1 is composed of a side opening die seat one 11 and a die seat two 12. The side opening die seat one 11 and the die seat two 12 apply force more uniformly than traditional ejectors, which can reduce the white top defect rate of thin-walled parts. The side opening of the die can ensure that the die maintains a stable posture in various complex working environments, especially on high-speed stamping production lines, which helps to produce products with accurate size and standard shape. The design of the side opening of the die makes the die adapt to different production needs and ensures stable work in different production environments. In addition, the design of the side opening of the die significantly reduces the time and workload required for die maintenance and cleaning.

[0048] The die core 2 is a matched movable die core and a fixed die core, which are respectively assembled on the die seat two 12 and the die seat one 11. The design of the die core 2 ensures accurate docking during the casting forming process, reducing the scrap rate caused by misalignment of the die core 2. The close cooperation between the movable die core and the fixed die core further improves the overall stability and service life of the die. At the same time, the material selection and surface treatment process of the die core 2 enable it to maintain excellent performance in high temperature and high pressure environment, ensuring the surface finish and dimensional accuracy of the casting.

[0049] The die seat two 12 slides along the guide rod penetrating the die seat one 11, and is used to drive the movable die core and the fixed die core to switch between the open die state and the closed die state. The die seat two 12 is pushed and moved by the existing air cylinder or hydraulic cylinder to realize the opening and closing actions of the movable die core and the fixed die core of the die seat two 12;

[0050] Refer to Figures 2-3, the carrier 3 includes a push block one 31 sliding in the horizontal direction and a push block two 32 sliding in the vertical direction, the push block one 31 and the push block two 32 slide along the surface of the movable die core for surrounding definition, the push block one 31 and the push block two 32 are connected with respective cylinders, the carrier 3 is driven to slide along the surface of the movable die core through the cylinders, and the carrier 3, the movable die core and the die cavity of the fixed die core surround and define the die casting cavity in the die closing state, wherein the pouring pipe assembled on the die seat one 11 passes through the fixed die core and communicates with the die casting cavity;

[0051] The design of the pouring pipe ensures smooth flow of the metal liquid, reduces pores and inclusions, and improves the quality of the castings. The precise fit of the push block one 31 and the push block two 32 effectively controls the material flow during the casting process, ensures uniform cooling of each part of the casting, and reduces deformation. The stability of the cylinder drive ensures reliable operation of the carrier 3 in high-speed production, further improving production efficiency and casting consistency. The sliding trajectory of the push block one 31 and the push block two 32 is optimized to reduce friction loss and prolong the service life of the parts. The special structure design of the pouring pipe effectively avoids the backflow and vortex phenomenon of the metal liquid, ensuring the compactness of the internal structure of the casting. In addition, the sealing device between the die seat one 11 and the die seat two 12 prevents leakage of high-temperature metal liquid, improving production safety and environmental protection. Intelligent control of the entire mold system realizes real-time monitoring and adjustment of the production process, further optimizing the production process.

The release agent pumped by the pump is first sent into the assembly seat 61, and then flows into the spray rod 6 through the opening of the spray rod 6 and is sprayed from the nozzle, so that the rotating action of the spray rod 6 does not affect the delivery of the release agent.

[0065] Working principle:

[0066] In the mold closing state, the die cavity of the movable die core and the fixed die core is surrounded by the carrier 3 to define a die casting cavity.

[0067] After the moving frame 4 moves to the clamping part 5 and clamps the automobile part casting and takes out the casting from the movable die core, the motor stops, and the push frame 81 moves towards the primary lever 721, the protruding push block of the push frame 81 is in contact with the locking block one 724, and the locking block one 724 is pushed away from the slot hole.
