Specific embodiments

[0014] The following details the embodiments of the present utility model. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model, and should not be construed as limiting the present utility model. The components of the embodiments of the present utility model described and shown in the drawings here can usually be arranged and designed in various different configurations.

[0015] In the present utility model, unless otherwise clearly specified and defined, terms such as "installation", "connection", "connection", "fixation" and other terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements.

[0016] The following further illustrates the present utility model in conjunction with the drawings and specific embodiments.

[0017] As Figures 1 to 3 shown, a barrel body mold for a gear transmission part in this embodiment includes a main body 1. The main body 1 includes a fixed mold 2 and a moving mold 3. The fixed mold 2 and the moving mold 3 are closed to form a cavity 4. A top side core-pulling 5 and a right side core-pulling 6 are slidably arranged in the cavity 4. The top side core-pulling 5 is connected to the top side oil cylinder 8 through the top side sliding seat 7, and the right side core-pulling 6 is connected to the right side oil cylinder 10 through the right side sliding seat 9. The fixed mold 2 is provided with a top side support 17 and a right side support 18. The top side oil cylinder 8 is installed on the top side support 17, and the right side oil cylinder 10 is installed on the right side support 18. Using a hydraulic cylinder for core-pulling instead of the traditional low-cost mechanical angle pin core-pulling, the core-pulling action of the hydraulic cylinder is smooth, with high safety and reliability, and can ensure the sequential order of the core-pulling action, ensuring reliable mold opening of the product and convenient on-site control.

[0018] The moving mold 3 is provided with a gate 11, which is sequentially connected to a sprue bushing 12, a main runner 13, a sub-runner 14 and a feed port 15. The feed port 15 is communicated with the cavity 4. The main runner 13 is arranged along the direction of the right-side core-pulling 6. The sub-runner 14 is arranged around the periphery of the right-side core-pulling 6. The feed port 15 is communicated with the right end of the cavity 4. A plurality of slag traps 16 are arranged in the main body 1, and the slag traps 16 are communicated with the left end of the cavity 4. The sprue bushing 12, the main runner 13, the sub-runner 14, the feed port 15 and the slag traps 16 are all formed by the closing of the fixed mold 2 and the moving mold 3.

[0019] When the barrel body mold works, the molten aluminum enters the sprue bushing 12 from the gate 11, flows through the main runner 13 and the sub-runner 14, and finally enters the cavity 4 at a high speed through the feed port 15. The flow state of the product is relatively smooth. Since it feeds along the wall of the right-side core-pulling 6, the erosion of the right-side core-pulling is small, the feeding position is not easy to stick to the mold, and the feed port is not easy to entrap air. The slag traps 16 can improve the surface quality of the end, increase the slag discharge at the end position, and discharge the die-casting cold material at the end into the slag traps.

[0020] The present invention is not limited to the above optional embodiments. Anyone can obtain other various forms of products under the inspiration of the present invention. However, no matter what changes are made in its shape or structure, as long as the technical solutions fall within the scope defined by the claims of the present invention, they all fall within the protection scope of the present invention.
