[0034] A capsule groove is arranged on one side of the moving mold 52 close to the side mold 7, a liquid capsule 54 is installed in the capsule groove, the liquid capsule 54 is placed below the butt plate 57, a pressing piece 71 is fixedly arranged on one side of the side mold 7 close to the guide column 53, the top of the pressing piece 71 is lower than the top of the inner wall of the capsule groove, and the outer part of the liquid capsule 54 is made of heat-resistant material.

[0035] When the side support mold 7 and the moving mold 52 move to the same height, at this time the guide column 53 enters the guide hole, under the pressure of the pressing piece 71, the liquid bag 54 will be squeezed into the bag groove, and part of the liquid bag 54 will be placed on the upper surface of the pressing piece 71, below the abutting position of the abutting plate 57 and the bottom of the forming groove 72, at this time the liquid bag 54 can play a role in cooling the riveted structure of the automobile part, and at the same time can seal the contact position of the abutting plate 57 and the bottom of the forming groove 72, avoiding waste of injection material.

[0036] Specifically, a plurality of groups of air cylinders 82 are fixedly connected inside the base 8, the telescopic end of the air cylinder 82 is fixedly supported by a support plate 811, a mounting hole is formed in the inside of the base 8, a top rod 88 is slidably arranged in the mounting hole, the bottom of the moving mold 52 is provided with a let -by slot 56, the top of the top rod 88 is matched with the let -by slot 56.

[0037] First, the telescopic end of the side electric control push rod 5 is controlled to be elongated, the moving mold 52 is pushed to slide along the guide rail 51, the let -by slot 56 moves synchronously in the process of moving the moving mold 52, the inner wall of the let -by slot 56 pushes the top rod 88 to move downward along the inner wall of the mounting hole, the support plate 811 is pressed downward in the process of moving the top rod 88 downward, the support plate 811 pulls the matching seat 80 downward through the support rod 89 arranged on the upper surface, so as to drive the mold core 6 and the side support mold 7 connected on both sides of the mold core 6 to move downward.

[0038] Specifically, the cooling water bag 81 is fixedly installed at the bottom of the base 8, the upper surface of the cooling water bag 81 is fixedly connected with the support plate 811, the inlet liquid bellow 83 and the outlet liquid bellow 84 are fixedly connected above the cooling water bag 81 respectively, the upper ends of the inlet liquid bellow 83 and the outlet liquid bellow 84 extend into the mold core 6, and the middle parts of the inlet liquid bellow 83 and the outlet liquid bellow 84 are connected with the one-way valve 85.

[0039] In the process of moving the support plate 811 upward, the cooling water bag 81 will be stretched, a negative pressure will be generated in the cooling water bag 81 in the process of being stretched, at this time the cooling water will be sucked into the cooling water bag 81 through the outlet liquid bellow 84, so as to achieve the effect of rapid circulation of the cooling water. Embodiment three:

[0040] The difference of this embodiment is that the mold core 6 is hollow, a plurality of groups of support rods 89 are fixedly connected to the upper surface of the support plate 811, the upper ends of the support rods 89 are fixedly connected with the matching seat 80, and the upper part of the matching seat 80 is fixedly connected with the mold core 6.

[0041] The hollow structure of the mold core 6 is beneficial to the assembly of internal components and heat dissipation during the production process. The support plate 811 moves upward under the push of the cylinder 82, and the ejector rod 88 slowly enters the gap slot 56. During the upward movement of the support plate 811, the support rod 89 pushes the matching seat 80 upward, and the matching seat 80 pushes the mold core 6 upward, which facilitates the removal of the processed automobile parts.

[0044] The inlet corrugated pipe 83 can be stretched or compressed to avoid damage during use. The inlet corrugated pipe 83 and the outlet corrugated pipe 84 are identical,

[0045] During the downward movement of the support plate 811, the cooling water in the cooling water bag 81 is squeezed out through the inlet corrugated pipe 83, and the cooling water in the inlet corrugated pipe 83 enters the pipeline connection hose 86 and the inner water bag 63 through the thin tube 87, so that the cooling water with lower temperature flows and changes before each injection molding, which can make the injection molded automobile parts cool faster and facilitate the demolding of the automobile parts.

[0046] Working principle: during the injection molding production of automobile parts, the injection material is first injected through the injection hole of the upper mold 2. After the injection is completed, the extension end of the main hydraulic cylinder 11 is shortened to drive the upper mold 2 upward. When the upper mold 2 and the lower mold 3 are completely separated, the side electric control push rod 5 placed on both sides of the lower mold 3 starts to work. The extension end of the two side electric control push rods 5 moves synchronously to pull the moving mold 52 along the guide rail 51 to move away from the mold core 6, which increases the stability of the moving mold 52 during movement and avoids damage to the automobile parts during demolding. The riveting structure forming groove 55 on one side of the moving mold 52 is separated from the riveting structure of the automobile parts. The riveting structure forming groove 55 and the butt joint plate 57 are provided with a step, which can increase the firmness of the end of the riveting structure of the automobile parts and avoid the phenomenon of breaking of the riveting structure of the parts during demolding.

[0047] When the moving die 52 moves a certain distance, the support plate 811 is upwardly moved at this time under the pushing of the air cylinder 82, and the top rod 88 slowly enters the let-out slot 56, and the cooperating seat 80 is upwardly moved by the support rod 89 during the upward movement of the support plate 811, and the cooperating seat 80 pushes the die core 6 upward, facilitating the taking down of the finished automobile part.

[0048] During the upward movement of the support plate 811, the cooling water bag 81 is stretched, and a negative pressure is generated in the cooling water bag 81 during the stretching, and the cooling water is sucked into the cooling water bag 81 through the liquid outlet corrugated pipe 84, so that the effect of rapid circulation of the cooling water is achieved.

[0049] During the automobile part injection molding, the telescopic end of the side electric control push rod 5 is first controlled to be elongated, the moving die 52 is pushed to slide along the guide rail 51, the let-out slot 56 is synchronously moved during the movement of the moving die 52, the inner wall of the let-out slot 56 pushes the top rod 88 to move downward along the inner wall of the mounting hole, the top rod 88 is pushed to move downward, the support plate 811 is pressed downward, the cooperating seat 80 is pulled downward by the support rod 89 arranged on the upper surface of the support plate 811, so as to drive the die core 6 and the side support die 7 connected on both sides of the die core 6 to move downward, when the side support die 7 and the moving die 52 move to the same height, the guide column 53 enters the guide hole at this time, the liquid bag 54 is squeezed into the bag groove under the pressing of the pressing piece 71, and a part of the liquid bag 54 is arranged on the upper surface of the pressing piece 71, below the abutting position of the butt joint plate 57 and the bottom of the forming groove 72, at this time, the liquid bag 54 can play a role in cooling the riveting structure of the automobile part, and can also seal the contact position of the butt joint plate 57 and the bottom of the forming groove 72, avoiding the waste of injection material.

[0050] During the downward movement of the support plate 811, the cooling water in the cooling water bag 81 is squeezed out through the liquid inlet corrugated pipe 83, the cooling water in the liquid inlet corrugated pipe 83 enters the pipeline connecting hose 86 and the inner water bag 63 through the thin tube 87, so that the cooling water with low temperature flows and is replaced before each injection, which can make the cooling of the injection automobile part faster, and is beneficial to the demolding of the finished automobile part.
