[0002] The electric vehicle frame base plate is one of the important components of an electric vehicle. Traditionally, electric vehicle frame base plates are generally made of plastic. Installing an electric vehicle frame base plate at the bottom of the electric vehicle frame effectively protects the electric vehicle frame.

[0003] In the current production process, electric vehicle frame base plates are generally manufactured using electric vehicle frame base plate molds. However, the irregularity of the edges of the electric vehicle frame base plates affects the processing efficiency of the formed electric vehicle frame base plates. To address this issue, we designed a slider positioning structure for electric vehicle frame base plate molds. Summary of the Invention

[0004] The purpose of this utility model is to provide a slider positioning structure for an electric vehicle frame base plate mold, so as to solve the problems mentioned in the background art.

[0005] The purpose of this utility model can be achieved through the following technical solution: a slider positioning structure for an electric vehicle frame base plate mold, including a lower mold base, a mold cavity is opened at the top of the lower mold base, a frame base plate is injection molded inside the mold cavity, an inner insert is provided on the inner side of the mold cavity, and multiple outer inserts are slidably connected to both sides of the lower mold base, and a separation part is fixedly provided on the side of the outer insert, and the separation part is embedded in the mold cavity wall.

[0006] In the above-mentioned electric vehicle frame base plate mold slider positioning structure, multiple sliding grooves are equally spaced on both sides of the lower mold base, and fixed plates are fixedly installed on both sides of the top of the multiple sliding grooves. A convex slider is slidably connected inside the sliding groove, and the bottom ends of the two fixed plates are in contact with the two sides of the top of the convex slider.

[0007] In the above-mentioned electric vehicle frame base plate mold slider positioning structure, the convex slider has an oblique insertion hole in the middle, a limiting guide post is inserted into the oblique insertion hole, the bottom of the limiting guide post extends into the inside of the slide groove, a connecting block is fixedly provided on the side of the limiting guide post, and the connecting block is fixedly connected to the top of the convex slider.

[0008] In the above-mentioned electric vehicle frame base plate mold slider positioning structure, one side of the top of the convex slider is fixedly connected to the bottom of the outer insert, and the outer side of the outer insert is inclined, and the inclination angle is the same as the inclination angle of the limiting guide post.

[0009] In the above-mentioned electric vehicle frame base plate mold slider positioning structure, through holes are provided on both sides of the bottom of the lower mold base, and inclined push rods are inserted into the two through holes. The top of the inclined push rods is fixedly connected to the bottom of the inner insert.

[0010] In the above-mentioned electric vehicle frame base plate mold slider positioning structure, a rotating block is fixedly provided at the bottom of the lower mold base. The rotating block is placed inside the fixed base and rotatably connected to both sides of the inner wall of the fixed base. The four corners of the bottom end of the fixed base are fixedly connected to the lower mounting plate by assembly bolts.

[0011] Compared with the prior art, the advantages of the slider positioning structure of the electric vehicle frame base plate mold of this utility model are as follows: the electric vehicle frame base plate mold can quickly slide to the mold cavity position during injection molding through the cooperation of the outer insert and the inner insert. When the upper mold base and the lower mold base separate, it can quickly separate from the formed frame base plate, which facilitates the rapid demolding of the frame base plate and improves the processing efficiency of the frame base plate.

Detailed Implementation

[0018] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0019] like Figure 1-5As shown, the electric vehicle frame base plate mold slider positioning structure of this utility model includes a lower mold base 1, a mold cavity 2 is opened on the top of the lower mold base 1, an inner insert 9 is provided on the inner side of the mold cavity 2, and multiple outer inserts 8 are slidably connected on both sides of the lower mold base 1. A separation part 14 is fixedly provided on the side of the outer insert 8, and the separation part 14 is embedded in the cavity wall of the mold cavity 2.

[0020] Specifically, the electric vehicle frame base plate mold, through the cooperation of the outer insert 8 and the inner insert 9, can quickly slide to the mold cavity 2 position during injection molding. When the upper mold base and the lower mold base 1 separate, it can quickly separate from the formed frame base plate 3, which facilitates the rapid demolding of the frame base plate 3 and improves the processing efficiency of the frame base plate 3.

[0021] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the electric vehicle frame base plate mold slider positioning structure of this utility model has multiple sliding grooves 4 equidistantly opened on both sides of the lower mold base 1. Fixing plates 10 are fixedly installed on both sides of the top of the multiple sliding grooves 4. A convex slider 5 is slidably connected inside the sliding groove 4. The bottom ends of the two fixing plates 10 are in contact with the two sides of the top of the convex slider 5.

[0022] Specifically, by sliding the convex slider 5 inside the groove 4, the outer insert 8 can be moved, thereby separating the separation part 14 on the side of the outer insert 8 from the mold cavity 2.

[0023] The convex slider 5 has a slanted insertion hole in the middle, and a limiting guide post 6 is inserted into the slanted insertion hole. The bottom of the limiting guide post 6 extends into the interior of the slide groove 4. A connecting block 15 is fixedly provided on the side of the limiting guide post 6, and the connecting block 15 is fixedly connected to the top of the convex slider 5.

[0024] Specifically, the connection block 15 facilitates the positioning and fixing of the limit guide post 6.

[0025] One side of the top of the convex slider 5 is fixedly connected to the bottom of the outer insert 8. The outer side of the outer insert 8 is inclined, and the inclination angle is the same as the inclination angle of the limiting guide post 6.

[0026] Specifically, the setting of the limiting guide post 6 facilitates the limiting of the movement direction of the convex slider 5.

[0027] Both sides of the bottom of the lower mold base 1 are provided with through holes, and inclined ejector rods 11 are inserted into the two through holes. The top of the inclined ejector rods 11 is fixedly connected to the bottom of the inner insert block 9.

[0028] Specifically, the inclined ejector rod 11 and the inner insert 9 are designed to facilitate the separation of the inner insert 9 from the mold cavity 2 by pulling the inclined ejector rod 11, which makes it easier to demold the formed frame base plate 3.

[0029] A rotating block 12 is fixedly provided at the bottom of the lower mold base 1. The rotating block 12 is placed inside the fixed base 7 and rotatably connected to both sides of the inner wall of the fixed base 7. The four corners of the bottom end of the fixed base 7 are fixedly connected to the lower mounting plate by assembly bolts 13.

[0030] Specifically, the mounting bolts 13 facilitate the connection between the mounting base 7 and the lower mounting plate.

[0031] In specific implementation, when the electric vehicle frame base plate mold is used for injection molding of the frame base plate 3, when the upper mold base and the lower mold base 1 are closed, the convex slider 5 moves inward with the cooperation of the limiting guide post 6, so that the outer insert 8 on the side of the convex slider 5 moves to the mold cavity 2. At the same time, the inclined ejector rod 11 pushes the inner insert 9 to move to the inside of the mold cavity 2 to form a complete mold cavity 2. Then the frame base plate 3 is injection molded. When the upper mold base and the lower mold base 1 are separated, the limiting guide post 6 is pushed outward by the upper mold base, so that the convex slider 5 moves outward. The outward movement of the convex slider 5 drives the outer insert 8 to separate from the mold cavity 2. At the same time, the inclined ejector rod 11 pulls the inner insert 9 to move, so that the inner insert 9 separates from the mold cavity 2, thereby realizing the separation of the frame base plate 3 from the mold cavity 2, which facilitates the demolding of the frame base plate 3.
