Description

Technical Field

[0001] The utility model relates to the technical field of die-casting equipment, and more specifically, the utility model relates to a shaft cover die-casting mold. Background Art

[0002] Die-casting refers to the process of die-casting a mold under the action of other external forces. The main feature of die-casting is that the metal fills the cavity under high pressure and high speed and forms under high pressure. Since the cost of casting equipment and molds is high, die-casting processes are generally only used for mass production of a large number of products. It is relatively easy to manufacture die-cast parts, and the incremental cost per item is very low. Die-casting is particularly suitable for manufacturing a large number of small and medium-sized castings. Therefore, die-casting is one of the most widely used casting processes.

[0003] For example, a shaft cover die-casting mold with the publication number CN216633353U includes a die-casting mold body. The die-casting mold body includes a base. A support frame is fixed on the base. A workbench is fixed on one side of the support frame. A mounting plate is welded on the workbench. A fixing frame is welded at the bottom of the mounting plate. A fixing groove is formed on the inner wall of the mounting plate. A fixing device is installed inside the fixing groove. A fixing plate is welded between the fixing frames. An electric push rod I is installed on the fixing plate. When the motor drives the parts on the rotating disk to rotate, a suction force is generated by the electromagnetic disk at the bottom, so that the parts are fixed on the rotating disk and rotate. After the parts are ejected from the opening inside the fixing device, the electric push rod pushes the grinding plate to push the parts on the rotating disk off, which is convenient for discharging.

[0004] However, according to the working principle proposed in the above patent, the applicant believes that although the above device can facilitate discharging to a certain extent, in actual use, when the shaft cover solidifies, it often adheres to the mold, and it is extremely inconvenient to take the finished product. The above device lacks the effective ability to help take the finished product, and it is easy to affect the production efficiency during use.

[0005] Therefore, a shaft cover die-casting mold is proposed for the above problems. Summary of the Utility Model

[0027] Through the movable rod 9 and the second hydraulic cylinder 10, it is convenient for the user to control the movement of the moving die base 1, so that it contacts the fixed die base 7, thereby forming a shaping chamber.

[0028] Among them, a feeding hole 11 is opened inside the second chamber 8. A pushing pipe 12 is fixedly connected to the back of the fixed die base 7.
