[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This automotive parts injection molding machine, through its structure consisting of a bracket, hydraulic cylinder, upper mold, lower mold, electric push rod, connecting shell, air supply pipe, condenser, motor, gear column, cooling pipe, and sealing plate, allows the user to extract air from the condenser during operation by using an exhaust fan. This creates negative pressure inside the condenser, drawing in outside air, which is then cooled to form cold air.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-5An injection molding machine for automotive parts includes a support 1, a hydraulic cylinder 2 fixedly mounted on the top of the support 1, an upper mold 4 fixedly mounted on the output shaft of the hydraulic cylinder 2, a base 3 located below the support 1, a lower mold 6 fixedly mounted on the top of the base 3, a fixing frame 5 fixedly mounted on the top of the lower mold 6, an electric push rod 7 fixedly mounted on the top of the fixing frame 5, a sealing plate 15 fixedly mounted on the output shaft of the electric push rod 7, a motor 11 fixedly mounted on the outer wall of the upper mold 4, a gear 12 fixedly mounted on the output shaft of the motor 11, and a sealing plate 14 meshing with the outer wall of the gear 12. The top of the mold 4 is provided with a connecting shell 8. The top of the upper mold 4 is fixedly equipped with a condenser box 10. The air inlet of the condenser box 10 is fixedly equipped with an air cylinder 17. The inner wall of the air cylinder 17 is fixedly equipped with a straight rod 18. The outer wall of the straight rod 18 is sleeved with a return spring 19. The bottom end of the return spring 19 abuts against a movable ring 20. The top of the movable ring 20 is fixedly equipped with a connecting rod 21. The top end of the connecting rod 21 is fixedly equipped with a filter element 22. The outlet of the condenser box 10 is fixedly equipped with an air supply pipe 9. The inner wall of the connecting shell 8 is provided with an exhaust fan 16. The outlet of the exhaust fan 16 is fixedly equipped with a cooling pipe 13.

[0024] In the above structure, the bracket 1, hydraulic cylinder 2, base 3, upper mold 4, fixed frame 5, lower mold 6, electric push rod 7, connecting shell 8, air supply pipe 9, condenser 10, motor 11, gear column 12, cooling pipe 13, sealing plate 14, sealing plate 2 15, and exhaust fan 16 allow the user to directly inject molding material into the upper mold 4 and lower mold 6 during operation. After the injection molding process, the raw material is molded by the upper mold 4 and lower mold 6. The rotation of the gear column 12 removes the sealing plate 14, allowing the cold air inside the condenser 10 to be evenly discharged through the cooling pipe 13 and come into contact with the raw material. This improves the cooling speed of the raw material in the molding machine and increases the user's work efficiency.

[0025] See Figure 1 and Figure 3 Motor 2 is fixedly assembled on the inner wall of the connecting shell 8, and the output shaft of motor 2 is fixedly assembled on the outer wall of the exhaust fan 16.

[0026] In the above structure, the user can use the second motor to rotate the exhaust fan 16, thereby expelling the air inside the condenser box 10. This creates a negative pressure inside the condenser box 10, drawing in outside air. This allows outside air to be filtered through the filter element 22, preventing impurities in the air from affecting the production quality of the product.

[0027] See Figure 1 and Figure 2There are four electric push rods 7, which are divided into two groups, and both groups of electric push rods 7 are symmetrically distributed along the top of the lower mold 6.

[0028] In the above structure, the two sets of electric push rods 7 allow the user to move the sealing plate 14 with sufficient space during operation, ensuring that the sealing plate 14 can move in two directions. This facilitates communication between the upper mold 4 and the lower mold 6 after injection molding and molding operations, thereby improving the cooling speed of the raw materials inside the molding machine.

[0029] See Figure 2 and Figure 4 The outer wall of the lower mold 6 is provided with a mating groove, and the inner wall of the mating groove is in close contact with the outer wall of the sealing plate 15.

[0030] In the above structure, the connecting groove and sealing plate 15 are designed to accommodate the sealing plate 15, thereby preventing the sealing plate 14 from shifting position and improving the stability of the sealing plate 15. This also ensures the pressing and forming effect of the upper mold 4 and the lower mold 6 on the raw material. After the sealing plate 15 is removed, the sealing plate 14 can be moved to the outside of the lower mold 6, thus ensuring that the cold air inside the condensation box 10 can contact the raw material and improve the cooling rate of the raw material.

[0031] See Figure 2 and Figure 4 The upper mold 4 has a movable groove on the outer wall of one end near the condenser box 10, and the inner wall of the movable groove is slidably connected to the outer wall of the sealing plate 14.

[0032] In the above structure, the movable groove and sealing plate 14 structure, after the sealing plate 15 is removed and the movable space provided by the movable groove, can ensure that the sealing plate 14 is moved out smoothly to the outside of the lower mold 6, so that cold air can come into contact with the raw material to assist the raw material to cool down quickly, thereby ensuring the normal operation of the molding machine.

[0033] See Figure 2 and Figure 4 The end of the gas supply pipe 9 is fixedly assembled with the air inlet of the connecting shell 8, and the interior of the upper mold 4 is connected to the interior of the condenser box 10 through the connecting shell 8 and the gas supply pipe 9.

[0034] In the above structure, the connecting shell 8 and the air supply pipe 9 enable the device to draw in outside air by using the exhaust fan 16 to create negative pressure inside the condenser box 10 during operation. This allows the air filtered by the filter element 22 to be cooled by condensation in the condenser box 10, thus allowing the cold air to be discharged between the upper mold 4 and the lower mold 6. This makes it convenient for the user to directly discharge the cold air to contact the raw materials, thereby improving the practicality of the device.

[0035] See Figure 4 and Figure 5 The outer wall of the movable ring 20 is slidably connected to the inner wall of the air cylinder 17. The outer wall of the movable ring 20 has a sliding hole, and the inner wall of the sliding hole is slidably connected to the outer wall of the straight rod 18.

[0036] In the above structure, through the set movable ring 20 and straight rod 18 structure, after the user completes the production operation, he can directly pull the filter element 22 to compress the reset spring 19, so that the filter element 22 can be moved out of the air cylinder 17, which makes it convenient for the user to clean the dust and impurities on the filter element 22, thereby improving the user's maintenance efficiency of the molding machine.

[0037] See Figure 4 The number of cooling pipes 13 is several, and the several cooling pipes 13 are evenly distributed along the inner wall of the upper mold 4.

[0038] In the above structure, by setting several cooling pipes 13, when the connecting shell 8 discharges cold air, the cooling pipes 13 can make the cold air contact the raw material evenly, avoiding the situation where heat accumulates in some areas and cannot be dissipated in time, thereby ensuring the heat dissipation effect of the cold air on the raw material and further improving the practicality of the molding machine.

[0039] Working Principle: After assembling the molding machine, the user can directly inject the raw material into the upper mold 4 and lower mold 6 through injection molding. The upper mold 4 then descends to mold the raw material, thus producing products of specific shapes. After injection molding, the user can rotate the gear column 12 by operating the motor 11. This, combined with the retraction of the output shaft of the electric push rod 7, causes the sealing plate 15 to rise, ensuring that the sealing plate 14 can be moved outside the upper mold 4. This allows the air drawn by the exhaust fan 16 to come into contact with the raw material, thereby accelerating the cooling speed of the raw material. During operation, the exhaust fan 16 rotates, causing the air inside the condenser 10 to be discharged, creating negative pressure to automatically draw in outside air. The filter element 22 filters the drawn air, preventing impurities and dust in the air from affecting the quality of the product. It also makes it easy for the user to remove the filter element 22 for cleaning or replacement, thus improving the user's maintenance efficiency of the molding machine.
