[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Reference Figure 1 and Figure 2 The utility model provides an embodiment: a batch injection molding device for automobile parts, including a first mold 1 and a second mold 2, the first mold 1 and the second mold 2 are both provided with a mold groove 5, the first mold 1 and the second mold 2 are both provided with a filling groove 6, a positioning component is provided on one side of the first mold 1, and a positioning groove 4 is provided inside the second mold 2, both sides of the first mold 1 are fixedly connected with a fixing block 7, the fixing block 7 is fixedly connected with a limiting column 10, and the outer wall of the limiting column 10 is symmetrically provided with a sliding connection limiting plate 11, A connecting rod 12 is rotatably connected to one side of the limit plate 11, a block 13 is rotatably connected to one end of the connecting rod 12, a support rod 14 is rotatably connected to one side of the block 13, a spring 15 is sleeved on the outer wall of the limit column 10, both ends of the spring 15 are fixedly connected between the limit plates 11, a connecting block 8 is fixedly connected to both sides of the second mold 2, a slot 9 is provided inside the connecting block 8, and the outer wall of the block 13 is embedded in the slot 9, and the positioning assembly includes a positioning pin 3, one end of the positioning pin 3 is fixedly connected to one side of the first mold 1, and the outer wall of the positioning pin 3 is slidably connected to the inside of the positioning slot 4;

[0030] Specifically, the first mold 1 and the second mold 2 are interlocked. The positioning pin 3 on one side of the first mold 1 slides into the positioning groove 4 for precise positioning. This step ensures the fit between the molds and ensures that the size of the product produced is accurate. Next, the first mold 1 will be embedded in the connecting blocks 8 on both sides of the second mold 2 through the card block 13 inside the fixing block 7. This process allows the card block 13 to fit with the card groove 9, thereby achieving stable fixation of the mold. This design ensures that the mold will not be displaced due to slight vibration or temperature changes during the production process, thereby ensuring the quality of the product. At the bottom of the mold, the card block 13 is connected to the limit plate 11 through the connecting rod 12. The limit plate 11 bracket can be self-supported by the tension of the spring 15. This design makes the mold more stable during closing and opening, avoiding product quality problems caused by unstable pressure. The other side of the connecting rod 12 is supported by the support rod 14, which further enhances the stability of the mold. During the use of the mold, the plastic is injected into the mold groove 5 through the filling groove 6. It is worth mentioning that there are multiple mold grooves 5 in the first mold 1 and the second mold 2. Such a design enables batch injection molding in the production process, greatly improving production efficiency. Injecting multiple molds at one time not only saves time, but also reduces production costs and improves the economic benefits of the enterprise.

[0031] Reference Figure 1 and Figure 3 A box body 16 is provided on one side of the second mold 2, a top cover 17 is provided on the top of the box body 16, a semiconductor refrigeration sheet 18 is fixedly connected to one side of the box body 16, a heat dissipation column 19 is fixedly connected to one side of the semiconductor refrigeration sheet 18, a heat dissipation fan 20 is fixedly connected to one side of the semiconductor refrigeration sheet 18, the heat dissipation column 19 is fixedly connected to one side of the semiconductor refrigeration sheet 18 in a rectangular array, a water pump 21 is fixedly connected to one side of the box body 16, an input end of the water pump 21 is fixedly connected to the inside of the box body 16, an output end of the water pump 21 is fixedly connected to a coil 22, one end of the coil 22 is fixedly connected to the inside of the box body 16, and an outer wall of the coil 22 is embedded in the second mold 2;

[0032] Specifically, when the second mold 2 dissipates heat, the semiconductor refrigeration sheet 18 plays a vital role. When the cooling process begins, the cooling surface of the semiconductor refrigeration sheet 18 will begin to perform cooling operations. This process is to achieve heat transfer and cooling by electronic migration of semiconductor materials. The low temperature generated by the cooling surface will gradually be transmitted to the box 16, causing the temperature inside the box 16 to drop. This process is similar to the semiconductor refrigeration sheet 18 being a cold source, and the cooling water in the box 16 will be affected by this cold source, and the temperature of the water will also drop accordingly. After the cooling process of the cooling water is completed, the water pump 21 will start to extract the cooled cooling water from the inside of the box 16. The water pump 21 transports the cooling water to the next link-the coil 22. In this process, the cooling water flows inside the coil 22 and takes away the heat from the second mold 2. After the heat is taken away, the cooling water will return to the inside of the box 16. This process is cyclical to ensure that the temperature inside the box 16 is always kept within a suitable range. At the same time, the heating surface of the semiconductor refrigeration sheet 18 will dissipate heat through the heat dissipation column 19. The heat dissipation column 19 is designed to increase the heat dissipation area of ​​the semiconductor cooling sheet 18, thereby improving the heat dissipation efficiency. The surface of the heat dissipation column 19 will blow the external air generated by the heat dissipation fan 20, so that the heat generated by the semiconductor material can be smoothly dissipated through the air flow.

[0033] Working principle: When using the batch injection molding device for automobile parts, first, the first mold 1 and the second mold 2 are buckled together, and the positioning pin 3 on one side of the first mold 1 slides into the positioning groove 4 for positioning. Then, the first mold 1 is embedded in the connecting blocks 8 on both sides of the second mold 2 through the clamping block 13 inside the fixing block 7, so that the clamping block 13 is embedded in the clamping groove 9 for fixing. The bottom of the clamping block 13 is connected to the limit plate 11 through the connecting rod 12. The limit plate 11 bracket can be supported by the tension of the spring 15. The other side of the connecting rod 12 is supported by the support rod 14. Then, the plastic is injected into the mold groove 5 through the filling groove 6. The mold groove 5 is provided with multiple , thereby achieving the effect of injecting multiple molds at one time, and then during cooling, the cooling surface of the semiconductor refrigeration plate 18 is cooled, and then the low temperature generated by the semiconductor refrigeration plate 18 is conducted to the box body 16, and the cooling water inside the box body 16 is cooled, and then the cooling water inside the box body 16 is pumped out by the input end of the water pump 21, and pumped out into the coil 22 through the output end of the water pump 21. When the cooling water flows inside the coil 22, it takes away the heat on the second mold 2, and then the cooling water returns to the box body 16 through the other end of the coil 22, and the heating surface of the semiconductor refrigeration plate 18 conducts heat through the heat dissipation column 19, and the external air is blown through the surface of the heat dissipation column 19 by the heat dissipation fan 20 to dissipate heat.
