Figure 4 for Figure 1 The schematic diagram of the upper mold shown includes a mold for manufacturing automotive parts, including mold structure 1, and a balancing pressure structure 2 is provided on the outside of mold structure 1.

[0026] Mold structure 1 includes an upper mold 101 and a lower mold 102;

[0027] The balancing pressure structure 2 includes a connecting plate 201 disposed on the top of the upper mold 101. Four telescopic rods 202 are evenly connected to the top periphery of the connecting plate 201 via hinges. An electric cylinder 203 is inserted into the top of each of the four telescopic rods 202. The tops of the four electric cylinders 203 are all connected to the same fixed plate 204 via hinges. The balancing pressure structure 2 also includes a connecting plate 205 disposed on the bottom of the lower mold 102. Four telescopic rods 206 are evenly connected to the bottom periphery of the connecting plate 205 via hinges. An electric cylinder 207 is inserted into the bottom of each of the four telescopic rods 206. The bottoms of the four electric cylinders 207 are all connected to the same fixed plate 208 via hinges.

[0028] It should be noted that: when the injection molding solution is added inside the lower mold 102, four electric cylinders 203 control the corresponding four telescopic rods 202 to extend downwards, so that the upper mold 101 approaches and connects with the lower mold 102, thereby applying pressure evenly on all four sides and preventing solution leakage. In addition, the four electric cylinders 203 can also extend and retract the four telescopic rods 202 to any length, and the four electric cylinders 207 control the four telescopic rods 206 to follow the corresponding telescopic rods 202 to extend and retract synchronously and in opposite directions, shaking the upper mold 101 and the lower mold 102 to remove air bubbles contained in the internal solution.

[0029] In the specific implementation process, refer to Figure 3 and Figure 4 As shown, the upper mold 101 is a convex mold, and the lower mold 102 is a concave mold.

[0030] In the specific implementation process, refer to Figure 3 and Figure 4 As shown, a sealing structure 3 is provided between the upper mold 101 and the lower mold 102. The sealing structure 3 includes a sealing ring 301 provided at the bottom of the upper mold 101 and a sealing groove 302 provided at the top of the lower mold 102. The sealing ring 301 is tightly inserted into the sealing groove 302.

[0031] It should be noted that the sealing ring 301 is tightly inserted into the sealing groove 302 to achieve a tight connection between the upper mold 101 and the lower mold 102, thus preventing leakage of the solution inside the upper mold 101 and the lower mold 102.

[0032] In the specific implementation process, refer to Figure 1 and Figure 2As shown, a positioning structure 4 is provided between the connecting plate 1 201 and the connecting plate 205. The positioning structure 4 includes positioning rods 401 located at the four corners of the bottom of the connecting plate 1 201. The bottom ends of the four positioning rods 401 are inserted into the corresponding positioning cylinders 405 located at the top of the connecting plate 205. The bottom ends of the four positioning rods 401 are inserted into buffer rods 402. The outside of the four buffer rods 402 is provided with buffer springs 403. The bottom ends of the four buffer rods 402 are provided with contact plates 404.

[0033] It should be noted that when the upper mold 101 and the lower mold 102 are close together, the four positioning rods 401 are inserted into the corresponding positioning cylinders 405 to perform alignment, so as to avoid the problem of misalignment between the upper mold 101 and the lower mold 102. At the same time, the four buffer springs 403, along with the buffer rods 402, retract into the corresponding positioning rods 401 to reduce the impact force when the upper mold 101 and the lower mold 102 are connected.

[0034] The working principle of the mold for manufacturing automotive parts provided by this utility model is as follows:

[0035] During use, the injection molding solution is added into the lower mold 102. Four electric cylinders 203 control the corresponding four telescopic rods 202 to extend downwards. The four positioning rods 401 on the upper mold 101 are inserted into the positioning cylinders 405 on the lower mold 102, so that the upper mold 101 approaches and aligns with the lower mold 102, achieving uniform pressure on all four sides and preventing solution leakage. In addition, the four electric cylinders 203 can also extend and retract the four telescopic rods 202 to any length. The four electric cylinders 207 control the four telescopic rods 206 to follow the corresponding telescopic rods 202 in a synchronous and opposite manner, shaking the upper mold 101 and the lower mold 102 to expel air bubbles contained in the internal solution. After the solution solidifies, the four electric cylinders 203, along with the four telescopic rods 202, pull up the upper mold 101 and separate it from the lower mold 102, facilitating the disassembly of automotive parts.
