Embodiment Construction
[0026] The present invention will be further described below in conjunction with embodiment.
[0027] Such as Figure 1 to Figure 3 Shown, a kind of die-casting mold that is used to manufacture electric rearview mirror motor end cover includes movable template 1 and fixed template 2, and movable mold core 11 is installed on the side of movable template 1 facing fixed template 2, fixed The template 2 is equipped with a fixed mold core 21 corresponding to the movable mold core 11. The movable mold core 11 cooperates with the fixed mold core 21. The movable mold core 11 is equipped with a movable mold insert 12 on the side away from the fixed mold core 21. The fixed template 2 A material pipe 3 with a main channel 31 is arranged on the side away from the movable platen 1, and a diverter cone 4 is provided corresponding to the material pipe 3 between the movable platen 1 and the fixed platen 2, and the diverter cone 4 is provided with a hole connecting the cavity of the casting T...

The invention relates to the technical field of pressure casting dies, in particular to a pressure casting die for manufacturing a motor end cap of an electric rearview mirror. A movable die insert is mounted on one side of a movable die core deviating from a fixed die core, a feed pipe with a main runner is arranged on one side of a fixed die plate deviating from a movable die plate, a spure spreader corresponding to the feed pipe is arranged between the movable die plate and the fixed die plate and provided with sub-runners communicated with a casting cavity, the main runner and the sub-runners are communicated and jointly form a casting system, an ejector sleeve device is arranged at the end of one side of the casting cavity deviating from the fixed die plate and comprises an ejector sleeve and an ejector pin matched with the ejector sleeve, the ejector pin and the fixed die plate are matched and jointly enclosed to form an inner peripheral wall of the casting cavity, and the movable die insert and the movable die plate are matched and jointly enclosed to form an outer peripheral wall of the casting cavity. The pressure casting die includes a plurality of filling cavities, a formed casting is ejected by the ejector sleeve device, and the pressure casting die has the advantages of convenience in ejecting products and high forming quality.
Description
technical field [0001] The invention relates to the technical field of die-casting molds, in particular to a die-casting mold for manufacturing electric rearview mirror motor end covers. Background technique [0002] The electric rearview mirror refers to the rearview mirror installed on both sides of the car and can be directly adjusted by the electric button; when adjusting the electric rearview mirror, the driver can easily adjust the rearview mirror without going out of the car perspective. [0003] The existing motors that drive the electric rearview mirrors of automobiles generally have a long axis column with a relatively large length in structure; Influenced by the structure of the die-casting mold, the gate position of the die-casting mold is often far away from the molding end of the shell, which will bring great inconvenience to the demoulding of the casting after cooling and solidification, and at the same time, the molding quality of the casting is not high.
