Description

Technical Field

[0001] This utility model relates to the field of flow channel assembly technology, and in particular to a flow channel assembly that prevents deformation of die-cast parts. Background Technology

[0002] The product structure in this technical solution is as follows: Figure 5 As shown, one end of the die-cast part is provided with four outwardly extending horizontal support structures, while the other end of the die-cast part is provided with two handles arranged side by side, and the handles are provided with a hole notch. Due to the low structural strength of the support structure and the handles, the structure is prone to deformation when the product is removed, and conventional flow channel components cannot remove the product. In order to solve the above problems, the flow channel components need to be improved. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a flow channel assembly that avoids deformation of die castings, which has the characteristics of improving product quality, avoiding deformation of die castings, facilitating air discharge in the mold cavity, and facilitating demolding.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: A flow channel assembly with a function to prevent deformation of die-cast parts is provided, including a die-cast part, a support venting flow channel, and a handle venting flow channel. Four rectangular support structures are provided at the left end of the die-cast part, and a support venting flow channel is installed between two support structures located on the same vertical plane. Two handles are arranged vertically side-by-side at the right end of the die-cast part, and a handle venting flow channel is installed between the front and rear ends of each handle. A front overflow flow channel connecting the two handles is provided at the front side of the right end of the die-cast part. Two rear overflow flow channels are arranged side-by-side at the rear side of the right end of the die-cast part. Each rear overflow flow channel includes an overflow channel body, a node flow channel, and a vertical connection interface. Both the upper and lower ends of the overflow channel body extend towards the die-cast part, and a vertical connection interface is provided at the extended ends of the overflow channel body. A node flow channel extending outwards is provided in the middle of the overflow channel body.

[0005] In this technical solution, the venting channels in the support legs are designed to facilitate the discharge of air from the support leg structure, ensuring that no air shrinkage cavities are generated within the support leg structure, thereby improving the structural strength at that location. This also facilitates product demolding. Similarly, the venting channels in the handle are designed to facilitate the discharge of air from the handle, improving its quality. Furthermore, the front and rear overflow channels are designed to add an auxiliary structure that acts as a support, ensuring that the handle does not deform during the ejection of the die-cast part.

[0006] As a supplement to this technical solution, the venting channels of the support legs and the venting channels of the handle adopt the same structure, both including a slag pocket channel, a side docking node, and a connecting channel. The connecting channel is vertical, and both ends of the connecting channel are bent toward the die casting. A slag pocket channel is provided at the end of the bent end of the connecting channel. A side docking node is provided on one side of the slag pocket channel to dock with the support leg structure or the handle.

[0007] In this technical solution, two slag bag flow channels are set to facilitate the discharge of excess air, avoid the presence of air shrinkage pores in the handle and support structure, and ensure the structural quality of both.

[0008] As a supplement to this technical solution, a secondary overflow node is provided in the middle of the connecting channel, and an outwardly extending outward flow channel is provided on the secondary overflow node. In this technical solution, the secondary overflow node is provided to improve the structural strength of the channel and facilitate the ejection of the material by a ejector pin.

[0009] As a supplement to this technical solution, the front left side of the die-cast part is provided with a first exhaust channel extending forward. The first exhaust channel includes a first branch channel, a second branch channel and an end node. One end of the first branch channel corresponds to one end of the second branch channel. One end of the first branch channel and the other end of the second branch channel extend outward and merge with each other. One end of the first branch channel and the merging end of the second branch channel converge into the end node. A front exhaust slag bag is provided below the first branch channel. The front exhaust slag bag is connected to the die-cast part and merges with the first branch channel through the channel.

[0010] In this technical solution, a first branch channel and a second branch channel are set to facilitate the concentrated discharge of air from the middle of the product. An end node is set to collect the overflowing aluminum liquid, and a front exhaust slag bag is set to facilitate the discharge of internal air.

[0011] As a supplement to this technical solution, an exhaust channel docking node that connects to the die-casting part is provided at one end of the first branch channel and the corresponding end of the second branch channel.

[0012] As a supplement to this technical solution, a second venting channel extending forward is provided on the front left side of the die casting. The second venting channel includes a docking channel, a vertical slag bale, and a tail channel. Two connecting nodes are provided on the docking channel. One end of the docking channel extends outward to form the tail channel. A vertical slag bale is provided at the end of the docking channel, and the vertical slag bale is docked with the die casting.

[0013] In this technical solution, a docking channel is set to facilitate the discharge of air from the right side of the die-casting part, and a vertical slag pot is set to prevent excessive aluminum liquid from escaping when internal air is discharged.

[0014] As a supplement to this technical solution, a circular lower protrusion is provided on the lower side of the rear overflow channel.

[0015] As a supplement to this technical solution, a casting runner is provided on the rear side of the die casting part. The casting runner includes a gate runner, a main runner and branch runners. A main runner extending towards both ends of the die casting part is provided on the front side of the gate runner. Several branch runners communicating with the die casting part are provided on the front side of the main runner.

[0016] Beneficial effects: This utility model relates to a flow channel assembly that prevents deformation of die-cast parts. By setting venting channels in the support legs, air can be easily discharged from the support leg structure, ensuring that no shrinkage cavities are generated in the support leg structure, thus improving the structural strength of the area and facilitating product demolding. By setting venting channels in the handle, air can be easily discharged from the handle, improving the quality of the handle. At the same time, by setting front overflow channels and rear overflow channels, an auxiliary structure as a support is added to ensure that the handle does not deform when the die-cast part is ejected. It has the characteristics of improving product quality, preventing deformation of die-cast parts, facilitating air discharge from the mold cavity, and facilitating demolding.
