Description

Two-way flow high-quality semi-solid die casting structure Technical Field

[0001] This invention relates to precision manufacturing technology, and particularly to the field of semi-solid die casting technology. Specifically, it relates to a bidirectional confluence high-quality semi-solid die casting structure. Background Technology

[0002] Semi-solid die casting is a net forming process in which a semi-solid slurry is forced to fill and solidify under pressure by the combined action of a die casting mold and an injection punch. It combines the advantages of semi-solid forming and die casting and has received widespread attention.

[0003] In the semi-solid die casting process, a large opening-shaped pouring gate is set on the side of the corresponding mold, and the die casting is completed by vacuuming the mold. However, due to the viscosity of the fluid in semi-solid die casting, the casting time is long, which affects the product preparation time. In addition, there is insufficient filling of the cavity in fine local areas such as the bottom protruding foot, which affects the product quality.

[0004] Therefore, it is necessary to provide a bidirectional, high-quality semi-solid die-casting structure to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a bidirectional, high-quality semi-solid die-casting structure.

[0006] The technical solution is as follows:

[0007] A bidirectional confluence high-quality semi-solid die casting molding structure includes an upper mold and a lower mold, the upper mold having an upper cavity and the lower mold having a corresponding lower cavity, the upper cavity and the lower cavity being combined to form a product molding cavity;

[0008] The product forming mold cavity is provided with a side semi-solid slurry inlet, and correspondingly, a flow-gating groove is provided on the upper mold. The flow-gating groove is provided with an upper flow-gating channel. The combination of the side semi-solid slurry inlet forms a bidirectional flow-gating high-quality stamping structure.

[0009] Furthermore, the upper confluence casting channel is designed to correspond to the cavity of the bottom protruding foot, forming a direct stamping structure for the corresponding micro-detailed local area.

[0010] Furthermore, the side semi-solid slurry inlet is used as the main punching inlet, forming a rapid side feeding channel. The micro-fine parts are punched directly through the micro-fine local punching structure, forming a rapid semi-solid forming structure that ensures the forming quality of the micro-fine parts.

[0011] Furthermore, the side semi-solid slurry inlet includes a main pouring channel, and the product molding cavity is provided with a pouring channel corresponding to the main pouring channel.

[0012] Furthermore, the gating system includes a lower mold gating system disposed on the lower mold and an upper mold gating system disposed on the upper mold, both of which are gradually narrowed flared openings.

[0013] Furthermore, an upper confluence impact ramp is provided on the lower die flow channel. The upper confluence impact ramp is used to enhance the side confluence pressure section, and together with the auxiliary micro-part punching, a bidirectional pressure boosting confluence structure is formed.

[0014] Furthermore, the product molding cavity is also equipped with a vacuum extraction device.

[0015] Compared with the prior art, the present invention forms a bidirectional confluence high-quality stamping structure by combining the upper confluence casting channel component with the side semi-solid slurry inlet, thus ensuring semi-solid molding efficiency and molding quality.
