Technical Field
[0001] This invention relates to the field of mold core-pulling structure technology, and in particular to a butt-shaped core-pulling structure for internal cavity forming. Background Technology
[0002] When manufacturing cylinder blocks, to facilitate the forming of the inner ring, a core-pulling structure with two outer rings in a circular shape is usually chosen to connect and ensure the inner ring structure. To ensure product quality, the conventional connecting core-pulling structure uses a spot cooling pipe to perform spot cooling on the inner ring part. This type of core-pulling has very low cooling efficiency, which affects the production efficiency of the product. To solve the above problems, the core-pulling structure needs to be improved. Summary of the Invention
[0003] The technical problem to be solved by this utility model is to provide a butt-shaped core-pulling structure for inner cavity molding, which has the characteristics of low modification cost, good cooling effect, ensuring the molding of the inner ring of the cylinder, and realizing rapid demolding.
[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: A butt-shaped core-pulling structure for inner cavity forming is provided, including a first slider seat, a second slider seat, a first core-pulling seat, and a second core-pulling seat. The first slider seat and the second slider seat are arranged opposite to each other. A first core-pulling seat is installed on the opposite end of the first slider seat, and a second core-pulling seat is installed on the opposite end of the second slider seat. An abutting first core-pulling seat and a second core-pulling seat are installed between the first core-pulling seat and the second core-pulling seat. Cooling inserts are installed on the opposite ends of both the first core-pulling seat and the second core-pulling seat. Two cooling water inlets and outlets are arranged side-by-side at the lower end of the cooling insert. A center opening is provided in the middle of the cooling insert. A cooling port corresponding to the cooling insert is provided at one end of the first core-pulling seat and the second core-pulling seat. A central protrusion corresponding to the center opening is provided in the middle of the cooling port. A cooling cavity is formed between the outer ring of the cooling insert and the cooling port.

[0010] As a supplement to this technical solution, a central slag trough is provided at the front of the docking face of the first and second core pullers. The central slag trough is connected to the front of the docking face of the first and second core pullers. By providing the central slag trough, excess aluminum liquid can be easily collected, ensuring product quality.
[0011] Beneficial effects: This utility model relates to a butt-shaped core-pulling structure for inner cavity molding. By installing cooling inserts, it ensures rapid cooling of the first and second core-pulling parts, thereby improving product production efficiency. The central opening facilitates the introduction of the central protrusion, making it easy to disassemble and replace the first and second core-pulling parts.

Figure 1 — Figure 8 As shown, the device includes a first slider seat 1, a second slider seat 2, a first core-pulling seat 3, and a second core-pulling seat 4. The first slider seat 1 and the second slider seat 2 are arranged opposite to each other. The first core-pulling seat 3 is installed on the opposite end of the first slider seat 1, and the second core-pulling seat 4 is installed on the opposite end of the second slider seat 2. The first core-pulling seat 3 and the second core-pulling seat 4 are connected by abutting first core-pulling seat 5 and second core-pulling seat 6. Cooling inserts 20 are installed on the opposite ends of the first core-pulling seat 3 and the second core-pulling seat 4. Two cooling water inlets and outlets 15 are arranged side by side at the lower end of the cooling insert 20. A center opening 14 is provided in the middle of the cooling insert 20.

A central protrusion 18 corresponding to the center opening 14 is provided in the middle of the cooling port 17. A cooling cavity 13 is formed between the outer ring of the cooling insert 20 and the cooling port 17.
[0023] In this technical solution, the installation of cooling inserts 20 is used to ensure rapid cooling of the first core puller 5 and the second core puller 6, thereby improving product production efficiency. The central opening 14 facilitates the introduction of the central protrusion 18, making it easy to disassemble and replace the first core puller 5 and the second core puller 6. The cooling cavity 13 is provided to increase the cooling area and improve cooling efficiency.
[0024] As a supplement to this technical solution, the lower end of the cooling insert 20 is provided with a snap-fit notch 16, and the cooling port 17 is provided with a limiting rib 19 that matches the snap-fit notch 16. The limiting rib 19 and the snap-fit notch 16 are used to limit the installation of the first core puller 3 and the second core puller 4.

[0028] As a supplement to this technical solution, a central slag-filling groove 8 is provided at the front of the joint between the first core puller 5 and the second core puller 6. The central slag-filling groove 8 is connected to the front of the joint between the first core puller 5 and the second core puller 6. By providing the central slag-filling groove 8, it is convenient to collect excess aluminum liquid and ensure the quality of the product.
[0029] Example
[0030] When producing the cylinder body, the mold is first closed. The first slider seat 1 and the second slider seat 2 are pushed by the hydraulic cylinder structure to close the first slider seat 1 and the second slider seat 2, so that the first core pull 5 and the second core pull 6 are connected. After completion, the aluminum liquid is injected into the mold cavity to produce the product. After the aluminum liquid fills the mold cavity, the excess aluminum liquid will enter the central slag trough 8. After the product is formed, the coolant is injected through the first inlet and outlet water pipe 9 and the second inlet and outlet water pipe 10. The coolant enters the first core pull 5 or the second core pull 6 through a cooling water inlet and outlet 15, so that the first core pull 5 and the second core pull 6 can be cooled quickly. The coolant is discharged along the cooling cavity 13 and through the second cooling water inlet and outlet 15.
