Description

Technical Field

[0001] This utility model relates to the field of die casting technology, and in particular to a die casting assembly with an insert. Background Technology

[0002] When producing a cylinder block structure, an insert needs to be built inside the cylinder block. The conventional production method requires two sets of mold structures: one mold is used to produce the insert, and the other mold is used to produce the product. During operation, the produced insert is directly placed into the mold for producing the product, and composite die casting is performed to ensure that the product and the insert are combined. However, this production method is very expensive. In order to solve the above technical problems, the die casting components need to be improved. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a die-cast component assembly with an insert, which has the characteristics of reducing production costs, improving production efficiency, and improving product quality.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: a die-casting component assembly with an insert is provided, including a die-casting component, an insert, and a gating assembly. The gating assembly is installed at the upper rear end of the die-casting component. The die-casting component is provided with a chamber structure. The insert is embedded in the inner cavity of the chamber structure. Two inlets and outlets that contact the insert are provided at the lower side of the chamber structure. An insert forming flow channel is provided on one side of the gating assembly. A branched flow channel is provided at the end of the insert forming flow channel. The insert is provided on the branched flow channel. An overflow slag is provided on the other side of the insert.

[0005] In this technical solution, an additional cavity for producing the insert is created by setting an insert forming flow channel. This allows the production of the product to be completed using only one set of molds. The branched flow channel facilitates the rapid filling of the insert, and the overflow slag facilitates the discharge of excess aluminum liquid, ensuring the integrity of the insert. The inlet and outlet facilitate the insertion of the core-pulling component into the cavity structure. The two core-pulling components can easily support the insert, making it easy to position and avoiding tilting or displacement problems during composite die casting.

[0006] As a supplement to this technical solution, the gate assembly includes a main channel and a sprue body. The sprue body is located on the rear side of the die casting. Two main channels extending to both sides are provided on the front side of the sprue body. The main channels surround the upper rear side of the die casting and are connected to the die casting through several nodes.

[0007] In this technical solution, two main channels are set up to quickly increase the injection speed of molten aluminum, which facilitates the accelerated forming of die-cast parts.

[0008] As a supplement to this technical solution, the insert includes an annular body, a support ring, and a concave protrusion. The lower end face of the annular body is provided with a support ring with a diameter smaller than that of the annular body, and the upper end side of the annular body is provided with a concave protrusion.

[0009] In this technical solution, a support ring is used for the installation of the inner insert, and an inwardly formed protrusion is used to improve the bonding ability with the die-cast part.

[0010] As a supplement to this technical solution, the concave protrusion is provided with a clearance notch, which further increases the bonding strength between the die-cast part and the insert.

[0011] As a supplement to this technical solution, a bottom venting slag is provided on the rear side of the lower end of the die casting. The bottom venting slag includes tail slag, a bottom flow channel, and a venting bifurcation flow channel. The front end of the tail slag is provided with a bottom flow channel extending toward the die casting. The bottom flow channel extends to both sides to form a venting bifurcation flow channel. The venting bifurcation flow channel is provided with at least one arc-shaped flow channel on the side near the die casting. Several slag pockets are provided on the arc-shaped flow channel to connect with the die casting.

[0012] By setting up combined bottom venting slag, it is easy to demold the whole product, avoiding the slag residue remaining in the mold during the die casting process, which would affect production efficiency, and also making it easier for workers to quickly remove the slag from the product.

[0013] As a supplement to this technical solution, the front side of the die casting is provided with two sets of double-layer venting slag connected to the die casting. The double-layer venting slag includes a tail flow channel, a frame flow channel and a branch flow channel. The rear end of the tail flow channel branches to both sides, and a frame flow channel is provided at the end of the branch. A branch flow channel extending towards the die casting is provided at the end of the frame flow channel. Several front slag bags are provided on the branch flow channel and connected to the die casting.

[0014] By setting up a double-layer exhaust slag system, the exhaust speed of the product is accelerated, further improving product quality.

[0015] As a supplement to this technical solution, the frame flow channel is vertical, with the bifurcated ends of the middle and tail flow channels connected together, and the upper and lower ends of the frame flow channel are bent toward the die casting part.

[0016] As a supplement to this technical solution, the branch channel is arc-shaped and surrounds the die-cast part.

[0017] Beneficial effects: This utility model relates to a die-casting component assembly with an insert. By setting an insert forming flow channel to create an additional cavity for producing the insert, production can be completed using only one set of molds. The branched flow channel facilitates rapid filling of the insert, and the overflow slag facilitates the discharge of excess molten aluminum, ensuring the integrity of the insert. The inlet and outlet facilitate the insertion of the core-pulling component into the cavity structure. The two core-pulling components can easily support the insert, making the insert easy to position and avoiding tilting or displacement problems during composite die casting. It has the characteristics of reducing production costs, improving production efficiency, and improving product quality. Attached Figure Description

[0040] Example

[0041] During production, the initial operation involves first using a 3D printer to process a single insert 5. Then, the insert 5 is placed inside the mold cavity, specifically inside the cavity structure 11. The positioning structure uses two core-pulling components in the mold to ensure the formation of the two inlets and outlets 12. The mold is then used for die casting. After the mold is opened, the product is removed. The insert 5 produced in the first production run is then removed using clamps or scissors and trimmed. After completion, production is carried out according to the same process as the first production run. This avoids the need to develop a set of molds for producing the insert 5, greatly reducing costs.
