Description

Technical Field

[0001] This utility model relates to the field of PCM composite material battery pack cover shaping and processing, specifically a PCM composite material battery pack cover cooling and shaping device. Background Technology

[0002] PCM composite material is a rapid prototyping technology based on fast-curing epoxy prepreg and compression molding. It uses continuous long glass fibers, resulting in high tensile strength and is widely used in battery pack manufacturing. Currently, existing PCM composite battery pack cover shaping devices suffer from slow natural cooling and low efficiency. Furthermore, the large size of the PCM composite battery pack cover means that a single shaping fixture cannot guarantee the quality of the extruded product. Utility Model Content

[0003] The purpose of this invention is to provide a cooling and shaping device for the top cover of a PCM composite material battery pack in order to solve the above-mentioned problems.

[0004] This utility model achieves the above-mentioned objective through the following technical solution: a cooling and shaping device for a PCM composite battery pack cover, comprising an outer pressure mold, a side pressure mechanism, a platform, a cylinder, a water-cooled cooler, and an inner support mold. The outer pressure mold and the inner support mold form a cooling and shaping placement space for the workpiece to be cooled and shaped. The circulation channel structure located inside the inner support mold is connected to the water-cooled cooler. The side pressure mechanism is provided at each placement hole distributed on the platform.

[0005] The edge pressing mechanism includes an L-shaped block, a strip-shaped pressing block, and a U-shaped component. The movable connecting hole on one side of the L-shaped block is movably connected to the outer end of the piston rod on the cylinder via a rotating shaft. The movable connecting hole on the other side of the L-shaped block is rotatably connected to the inside of the U-shaped component via a rotating shaft. A strip-shaped pressing block is fixedly installed at one end of the L-shaped block. The strip-shaped pressing block moves to contact the corresponding structural part at the edge of the outer pressing mold body.

[0006] Preferably, the cylinder body end is fixedly connected to the bottom opening of the mounting hole.

[0007] Preferably, the bottom of the U-shaped component is fixedly connected to one side of the top opening of the mounting hole.

[0008] Preferably, the platform is installed on the top of the frame, and the bottom of the platform is fixedly connected to the corresponding part of the water-cooled cooler.

[0009] Preferably, a control cabinet is installed at the bottom of the frame.

[0010] Preferably, a control switch is installed at one of the corners of the top of the platform.

[0011] Compared with the prior art, the advantages of this utility model are as follows: by applying pressure to the edge parts corresponding to the outer pressure mold body through multiple distributed edge pressure mechanisms, it can not only apply force to squeeze and position the workpiece to be cooled and shaped at a high temperature between the outer pressure mold body and the inner support mold body, but also improve the fullness of contact between the structural shape of each part of the workpiece to be cooled and shaped and the mold structure. In addition, the operation of the water-cooled cooler allows circulating cold water to enter the interior of the inner support mold body to exchange and cool the high temperature on the workpiece to be cooled and shaped, thereby accelerating the cooling and shaping speed of the workpiece to be cooled and shaped, resulting in high product quality and a more uniform appearance structure.

[0020] Please see Figure 1-3 As shown, a cooling and shaping device for a PCM composite battery pack cover includes an outer pressure mold 1, a side pressure mechanism 2, a platform 3, a cylinder 4, a water-cooled cooler 5, and an inner support mold 510. The outer pressure mold 1 and the inner support mold 510 form a cooling and shaping placement space for the workpiece 9 to be cooled and shaped. The circulation channel structure located inside the inner support mold 510 is connected to the water-cooled cooler 5. The side pressure mechanism 2 is provided at each placement hole 310 distributed on the platform 3.

[0021] The edge pressing mechanism 2 includes an L-shaped block 210, a strip pressing block 220, and a U-shaped component 230. The movable connecting hole 211 on one side of the L-shaped block 210 is movably connected to the outer end of the piston rod 410 on the cylinder 4 via a rotating shaft. The movable connecting hole 211 on the other side of the L-shaped block 210 is rotatably connected to the inside of the U-shaped component 230 via a rotating shaft. The strip pressing block 220 is fixedly installed at one end of the L-shaped block 210. The strip pressing block 220 contacts the corresponding structural part at the edge of the outer pressing mold body 1 by moving.

[0022] The cylinder body end of the cylinder 4 is fixedly connected to the bottom opening of the mounting hole 310; the bottom of the U-shaped part 230 is fixedly connected to one side of the top opening of the mounting hole 310.

[0023] The platform 3 is installed on the top of the frame 8, and the bottom of the platform 3 is fixedly connected to the corresponding part of the water-cooled cooler 5. A control cabinet 6 is installed at the bottom of the frame 8, and a control switch 7 is installed at one of the corners of the top of the platform 3.

[0024] Working principle: The hot workpiece 9 to be cooled and shaped is placed on the inner support mold 510, and then the outer pressure mold 1 is placed on the outside of the workpiece 9 to be cooled and shaped. Then, the cylinder 4 extends and drives the movable L-shaped block 210 to rotate sideways with the rotating connection part at the U-shaped part 230 as the rotation point. This causes the strip pressure block 220 connected to the corresponding end of the L-shaped block 210 to press on the corresponding part of the edge of the outer pressure mold 1. The outer pressure mold 1 and the inner support mold 510 can apply force to squeeze and shape the workpiece 9 to be cooled and shaped. At the same time, the water-cooled cooler 5 runs and circulates cold water into the inner support mold 510 to exchange heat and cool the high temperature of the workpiece 9 to be cooled and shaped, thus accelerating the cooling and shaping speed of the workpiece 9 to be cooled and shaped.

[0025] Compared with existing technologies, the difference lies in the fact that multiple distributed edge pressing mechanisms 2 apply pressure to the corresponding edge parts of the outer pressing mold body 1, which can not only forcefully squeeze and position the high-temperature workpiece 9 to be cooled and shaped between the outer pressing mold body 1 and the inner supporting mold body 510, but also improve the fullness of contact between the structural shape of each part of the workpiece 9 to be cooled and shaped and the mold structure. In addition, the operation of the water-cooled cooler 5 allows circulating cold water to enter the inner supporting mold body 510 to exchange and cool the high temperature of the workpiece 9 to be cooled and shaped, thereby accelerating the cooling and shaping speed of the workpiece 9 to be cooled and shaped, resulting in high-quality finished products with more uniform appearance and structure.
