Description

Technical Field

[0001] The utility model relates to the field of casting molds for automobile parts, in particular to a mold for a glass lifting control bracket of a new energy vehicle door mold. Background Art

[0002] There are multiple inlays on the glass lifting control bracket of the automobile door mold. Traditionally, an external hot riveting method is used for installation. Usually, after ultrasonic heating, the metal part is welded to the injection molding bracket. However, the durability and anti-fatigue performance of this connection method are poor. The connection strength between the metal part and the injection molding part cannot meet the use requirements. When a convex platform for an anti-disconnection structure is set at the connection between the metal part and the injection molding part, the plastic at the connection turns outwards after hot melting, making the product unsightly. Moreover, the center distance between the inlays may deviate, reducing the accuracy of the product. Additionally, the traditional hot riveting method has low efficiency and poor quality. Summary of the Invention

[0003] The utility model aims to solve the deficiencies of the prior art and provides a mold for a glass lifting control bracket of a new energy vehicle door mold.

The other two vertices of the injection molding table are connected with fixed support columns. One lower mold base and one lower mold body are fixed on each side of the central support column on the bottom turntable. The upper mold body is connected below the injection molding table in a vertically movable manner. An upper mold cover is connected above the upper mold body. An ejection mechanism is arranged below the lower mold body in the lower mold base. A mold cavity is arranged in the lower mold body. A mold core is placed in the mold cavity. The ejection mechanism extends upwards into the mold cavity. The injection system includes an injection port, a hot runner cavity, and a transverse hot runner. The injection port is located at the upper mold cover. The injection port communicates with four hot runner cavities. Each hot runner cavity corresponds to a mold cavity. The hot runner cavities are arranged on the upper mold body. The bottom of the hot runner cavity communicates with three transverse hot runners in different directions. The transverse hot runners extend to the bottom surface of the upper mold body through vertical pouring point pipes. The pouring ports of the pouring point pipes correspond to the pouring points on the mold core. A number of cooling pipes are distributed on both the upper mold body and the lower mold body.

[0006] A ejector pad is arranged between the lower part of the ejection mechanism and the bottom turntable.
