[0034] Combination Figures 1-3 A vehicle body component injection molding mold for rapid cooling includes a mounting frame 1 and a fixed base 2 fixedly connected to the bottom of the mounting frame 1. A telescopic cylinder 11 is fixedly connected to one side of the mounting frame 1, and a heat sink box 12 is fixedly connected to one end of the mounting frame 1. A connecting block 111 is fixedly connected to the output end of the telescopic cylinder 11. An upper mold 112 is fixedly connected to one side of the connecting block 111. An injection port 113 is fixedly connected to the top of the upper mold 112. A lower mold 124 is slidably connected to the top of the mounting frame 1. The mounting frame 1 is provided with a transmission mechanism, which achieves the effect of rapid demolding.

[0035] The present invention will be further described below with reference to the embodiments.

[0036] Example 1:

[0037] To address the problem that existing injection molding dies often lack efficient cooling components, resulting in inadequate cooling of workpieces during injection molding of car body parts, leading to prolonged demolding times and consequently affecting equipment efficiency, the following solution is disclosed. Please refer to the following for details. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 as well as Figure 7The transmission mechanism includes a servo motor 121 fixedly connected inside the heat sink 12. A transmission screw 122 is fixedly connected to the output end of the servo motor 121. A connecting block 123 is threadedly connected to the transmission screw 122. The connecting block 123 is fixedly connected to the lower mold 124, which matches the upper mold 112. A telescopic cylinder 13 is fixedly connected to the top of the fixed base 2. Two sets of telescopic cylinders 13 are provided. A transmission block 131 is fixedly connected to the output end of the telescopic cylinder 13. A water tank 132 is fixedly connected to one side of the transmission block 131. A water injection pipe 133 is fixedly connected to one side of the water tank 132, which matches the lower mold 124. An interface pipe 15 is also fixedly connected to one side of the mounting bracket 1. One end of the interface pipe 15 is fixed... A sealing ring 151 is fixedly connected to the lower mold 124. A connecting pipe 152 is fixedly connected to one side of the lower mold 124. Both the connecting pipe 152 and the interface pipe 15 are provided in two sets. A sealing groove 1521 is opened on one side of the connecting pipe 152. The sealing groove 1521 slides with the sealing ring 151. A return pipe 153 is fixedly connected inside the lower mold 124. The return pipe 153 is connected to the connecting pipe 152. When injection molding is required, the telescopic cylinder 11 can be activated. The telescopic cylinder 11 moves the connecting block 111, thereby moving the upper mold 112. After the upper mold 112 and the lower mold 124 are in contact, the operator can inject the lower mold 124 through the injection port 113. After the injection is completed, the telescopic cylinder located on the top of the fixed base 2 can be activated. The telescopic cylinder 13 moves the transmission block 131, which in turn moves the water tank 132. Before using the water tank 132, the operator can inject water into the water tank 132 through the water injection pipe 133, which can cool the lower mold 124. Since the telescopic cylinder 13 is a waterproof cylinder, the overflowing water will not affect the telescopic cylinder 13. When the water tank 132 places the lower mold 124 inside, it can quickly cool the mold inside the lower mold 124. When the water in the water tank 132 needs to be replaced, a container can be pushed under the water tank 132, and the drain pipe 134 can be opened to drain the water in the water tank 132. New cold water can then be poured into the water tank 132 through the water injection pipe 133. The operator can also connect the mold cooling unit to the interface pipe 15 and inject cooling water into the interface pipe 15. The cooling water enters the return pipe 153 through the connecting pipe 152, and the return pipe 153 then emits cool air, which can further cool the injection molded parts inside the lower mold 124. After cooling is complete, the servo motor 121 can be started. The servo motor 121 drives the transmission screw 122 to rotate, which in turn moves the connecting block 123, allowing for the next operation on the workpiece inside the lower mold 124. At this time, due to the sealing groove 1521 and sealing ring 151 on one side of the connecting pipe 152, the interface pipe 15 can be separated from the connecting pipe 152, and there will be no water leakage during subsequent connection processes.This ensures that subsequent operating procedures are not affected, allowing for rapid cooling of the vehicle body parts by staff and improving efficiency.

[0038] Example 2:

[0039] To address the common problem that existing injection molds often lack effective ejection mechanisms, requiring workers to use additional tools to remove body parts after injection molding, the following solution is proposed. Please refer to the following for details. Figure 4 and Figure 5 The mounting bracket 1 has a placement opening 14 at its top, and an opening assembly 141 is formed inside the placement opening 14. A connecting box 142 is fixedly connected to the bottom of the mounting bracket 1. An electric push rod 143 is fixedly connected inside the connecting box 142. A transmission frame 144 is fixedly connected to the output end of the electric push rod 143. A lifting block 145 is fixedly connected to one end of the transmission frame 144. Two sets of lifting blocks 145 are provided. The lifting blocks 145 slide with the opening assembly 141. An I-shaped block 146 is slidably connected inside the opening assembly 141. The I-shaped block 146 and the lifting block 145 slide with each other. Matching 45, when the servo motor 121 is started and the lower mold 124 is moved to the placement port 14, the electric push rod 143 can be started. The electric push rod 143 drives the transmission frame 144 to move, which in turn drives the lifting block 145 to move, which in turn moves the I-shaped block 146. The I-shaped block 146 can push out the workpiece inside the lower mold 124, making it easier for the operator to take out the workpiece. This achieves the function of pushing out the workpiece inside the lower mold 124 more quickly, improving the usage effect.
