Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of die-casting molds, in particular to a die-casting mold for an engine case which is easy to demould. Background Art
[0002] Die casting is a metal casting process characterized by applying high pressure to the molten metal in the mold cavity. The mold is usually made of a higher strength alloy, and this process is somewhat similar to injection molding. Most die castings are iron-free, such as zinc, copper, aluminum, magnesium, lead, tin, lead-tin alloys and their alloys. Depending on the type of die casting, a cold chamber die casting machine or a hot chamber die casting machine is required. The existing patent, patent announcement number CN214768815U, discloses a die casting mold that is easy to demold, including a movable die group and a fixed die group that cooperates with the movable die group, and the movable die group is connected with the fixed die group; the movable die group is provided with a demolding group, and the demolding group includes a push die plate, and a plurality of push die columns fixedly connected to the push die plate, and the push die column passes through the movable die pad and the movable die support plate, and the push die plate is located above the movable die pad and serves as the bottom wall of the cavity. The die-casting mold that is easy to demould is simple in structure and easy to operate. The ejector plate is used instead of the ejector pin to directly push the mold, which can prevent thinner alloy products from being stabbed and deformed by the ejector pin. A plurality of ejector columns jointly push the ejector plate, so that the ejector group is evenly stressed, and the phenomenon of ejector pin breakage is avoided, so that demoulding is smoother.
[0003] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: in actual application, the die-casting mold is difficult to demold during the demolding process, and in the subsequent use process, the surface of the shell after die-casting will be uneven, affecting the subsequent die-casting operation and reducing the efficiency of the use of the mold. Therefore, we propose a die-casting mold for an engine case that is easy to demold to solve the above-mentioned problems. Utility Model Content

[0025] A cavity is formed inside the base 1, and a sliding block 13 is slidably connected inside the cavity. The top of the sliding block 13 penetrates through the base 1 and extends to the outside of the base 1. A hydraulic rod 14 is fixedly installed on one side of the sliding block 13, and one end of the hydraulic rod 14 is fixedly connected to one side of the inner wall of the cavity.
[0026] Control the telescopic rod 9 to drive the push rod 10 to move, so that the positioning ring 11 and the conical rod 12 on the push rod 10 are inserted into one side of the housing 4. Since the conical rod 12 is adapted to the conical hole on the housing 4, when the conical rod 12 is inserted into the inner wall of the housing 4, one end of the conical rod 12 is flush with the inner wall of the housing 4. When the die-casting is completed, control the telescopic rod 9 to drive the positioning ring 11 and the conical rod 12 on the push rod 10 to separate from the housing 4. Then, inject water into the square tube 5 through the water pipe 6. Subsequently, the water enters the inside of the housing 4 through the conical hole. Then, the water contacts the components inside the housing 4 and also squeezes the components inside the housing 4, so as to facilitate the subsequent demoulding operation and subsequent use, and improve the use convenience of the die.

[0040] During operation, control the telescopic rod 9 to drive the push rod 10 to move, so that the positioning ring 11 and the conical rod 12 on the push rod 10 are inserted into one side of the housing 4. Since the conical rod 12 is adapted to the conical hole on the housing 4, when the conical rod 12 is inserted into the inner wall of the housing 4, one end of the conical rod 12 is flush with the inner wall of the housing 4. When die casting is completed, control the telescopic rod 9 to drive the positioning ring 11 and the conical rod 12 on the push rod 10 to separate from the housing 4. Then, inject water into the inside of the square pipe 5 through the water pipe 6. Subsequently, the water enters the inside of the housing 4 through the conical hole. Subsequently, the water contacts the components inside the housing 4 and also squeezes the components inside the housing 4, which facilitates subsequent demoulding operations, is convenient for subsequent use, and improves the convenience of using this mold. During the use process, control the hydraulic rod 14 to work.
