Description

Technical Field

[0001] The utility model belongs to the technical field of injection molding production, in particular to an injection molding die for metal accessories. Background Art

[0002] Metal injection molding is a processing method in which molten metal materials are injected into a mold and then cooled and solidified to form the desired parts or products. Similar to plastic injection molding, metal injection molding is also done by heating the metal material to a molten state and then injecting the molten metal material into a mold for molding. It is usually used to manufacture products with high requirements such as high precision, high strength, high wear resistance, and high corrosion resistance, such as automotive engine parts, aircraft engine parts, medical equipment, electronic equipment, etc.

[0003] After searching, the authorization announcement number CN216032175U and the authorization announcement date 2022.03.15 disclose a new type of automobile parts injection mold, including a top pressing plate, a feeding port is provided at the middle end of the top pressing plate, a recessed armrest is provided on the front and rear end faces of the top pressing plate, a lifting support rod is fixedly connected to the outer side of the bottom end of the top pressing plate, and a lower mold is movably connected to the outer side of the bottom end of the lifting support rod, and a pressing top plate is fixedly connected to the middle end of the bottom end of the top pressing plate, a mother template is provided at the top of the lower mold, and a control panel is fixedly connected to the front end face of the lower mold. The new type of automobile parts injection mold has a feeding port that can pour materials to help automobile parts to be quickly formed, and the recessed armrest can help the top pressing plate to be raised and lowered, which increases the use effect of the injection mold. The lifting support rod can move up and down during use to help the mold to be quickly demolded after forming. The design of the fixed plate improves the stability of the lifting support rod when moving, and further improves the activity sensitivity of the top pressing plate.

[0004] However, the existing technology has the following shortcomings:

[0005] 1. When the above-mentioned new type of automobile parts injection mold is in use, the cooling fan can blow air during use, and the cool air is directly transmitted to the mother mold through the inside of the lower mold, thereby increasing the cooling effect of the parts. However, in actual use, the heat dissipation efficiency of the airflow generated by the cooling fan to blow away the heat is low, resulting in poor heat dissipation effect;

[0006] 2. When the above-mentioned new type of automobile parts injection mold is in use, the pressing top plate is moved upward to expose the parts, and then the parts are separated from the lower mold to take out the injection-molded parts. However, in actual operation, since the surface temperature of the parts is still high after the injection molding is completed, burns are likely to occur, and the labor intensity of the operator is increased.
