Description

Technical Field

[0001] This utility model belongs to the field of electric vehicle technology and relates to an automatic reset mechanism for the top block of an electric vehicle plastic part mold. Background Technology

[0002] Electric vehicles are divided into AC electric vehicles and DC electric vehicles. Generally speaking, electric vehicles use batteries as an energy source and convert electrical energy into mechanical energy through components such as controllers and motors to move. The speed is changed by controlling the current. The front of the electric vehicle is equipped with a front cover, which needs to be injection molded during processing.

[0003] In traditional injection mold structures, the bottom of the molding ejector block is simply pushed up and lifted by a cylinder to remove material during auxiliary molding. Because the bottom rod is long, the top of the molding ejector block is not supported, which can easily cause it to shift and slide during molding, requiring improvement. Summary of the Invention

[0004] The purpose of this utility model is to provide an automatic reset mechanism for the top block of an electric vehicle plastic part mold, so as to solve the problems mentioned in the background art.

[0005] The objective of this utility model can be achieved through the following technical solution: an automatic reset mechanism for the top block of an electric vehicle plastic part mold, comprising a base plate, a lower mold base, an inner mold core, and a side forming block. The lower mold base is located at the top of the base plate, and the inner mold core is located at the center of the top of the lower mold base. Side forming blocks and forming top blocks are respectively located on both sides of the inner mold core. Limiting side frames are provided on both sides of the lower mold base. A supporting side is provided on the inner side of the limiting side frame to cooperate with the side forming blocks and forming top blocks. A limiting end face is provided on the outer end face of the supporting side. A positioning groove is provided inside the limiting end face. A positioning pin one is provided inside the positioning groove. A positioning pin two is provided on one side of the positioning pin one.

[0006] In the above-mentioned automatic reset mechanism for the top block of the electric vehicle plastic part mold, the bottom end of the molding top block is connected to an inclined push rod, a reset spring is provided on one side of the top of the inclined push rod, and the top end of the reset spring is connected to the bottom of the lower mold base.

[0007] In the above-mentioned automatic reset mechanism for the top block of the electric vehicle plastic part mold, the top of the inner mold core is provided with multiple push grooves, the bottom of the lower mold base is provided with a push rod, and the top of the push rod is placed inside the push groove.

[0008] In the above-mentioned automatic reset mechanism for the top block of the electric vehicle plastic part mold, the inner mold core has a side cavity one and a side cavity two. The side forming block is placed inside the side cavity one, and the forming top block is placed inside the side cavity two.

[0009] In the above-mentioned automatic reset mechanism for the top block of the electric vehicle plastic part mold, the side of the molding top block is provided with a positioning end face that cooperates with the limiting end face, and the surface of the positioning end face is provided with positioning pin holes that cooperate with positioning pin one and positioning pin two.

[0010] Compared with the prior art, the advantages of the automatic reset mechanism for the top block of the electric vehicle plastic part mold of this utility model are:

[0011] This application provides side forming blocks and forming top blocks on both sides of the lower mold base to assist in forming with the inner mold core. The lower mold base also has a movable limiting side frame on its side. The inner side of the limiting side frame has a supporting side and a limiting end face. The supporting side can be pressed against the side of the forming top block, and the limiting end face is attached to the side of the forming top block. Positioning pin one and positioning pin two are inserted into the positioning pin holes on the side of the forming top block to support and limit the forming top block. In this way, the forming top block is more stable and less prone to displacement during assisted forming. Furthermore, a return spring is provided at the inclined ejector rod at the bottom of the forming top block. After the forming top block is ejected, it can automatically return to its original position through the return spring. Attached Figure Description
