When the mold is replaced, the cooling pipe needs to be reinstalled and disassembled, resulting in low production efficiency. Therefore, an injection molding machine for producing bean paste boxes is proposed to solve the above problems. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the utility model provides an injection molding machine for producing bean paste boxes, which has the advantage of easy replacement of specifications and solves the problem of needing to reinstall and disassemble the cooling pipe when replacing the mold.

[0006] To achieve the above-mentioned object, the utility model provides the following technical solution: an injection molding machine for producing bean paste boxes, comprising a support table, two support rods are fixed on the top of the support table, a support plate is fixed between the two support rods, a driving assembly is provided on the top of the support plate, a push plate slidably connected to the support rods is fixed on the bottom of the driving assembly, an upper mold is fixed on the bottom of the push plate, and an upper molding block is fixed inside the upper mold;

[0010] Furthermore, the driving assembly includes a driving motor fixed to the support plate, the output shaft of the driving motor is fixed with a driving rod penetrating to the bottom of the support plate, and the bottom of the driving rod is threadedly connected with a push rod.

[0019] Furthermore, the cooling assembly includes a radiator, a cold water pipe, a hot water pipe and an annular cooling pipe. The right side of the support platform is fixed to the radiator, and the top of the radiator is fixed to the cold water pipe and the hot water pipe respectively. The cold water pipe and the hot water pipe are fixed to the annular cooling pipe that penetrates into the lower mold.

[0020] By adopting this technical solution, a water pump is fixed at the bottom of the cold water pipe, and the water pump is fixed to the heat dissipation radiator. After starting the water pump, the cooling water will enter the interior of the annular cooling pipe through the cold water pipe to cool the lower mold, and the cooling water after the temperature rises will flow back to the heat dissipation radiator through the hot water pipe for heat dissipation.

[0021] Furthermore, sliding blocks are fixed inside the upper mold and the lower mold, and a sliding groove is provided inside the extension block to be slidably connected to the sliding block.

[0022] By adopting this technical solution and arranging the sliding block and the sliding groove, the movement of the extension block is made more stable.

[0036] In general, the cooling efficiency of the molded parts can be improved by setting the cooling assembly, and the molded parts can be easily ejected by setting the ejection assembly, thereby effectively improving the overall processing efficiency and making the overall process more practical.

[0037] See also Figures 3 to 4The fixing assembly 16 in this embodiment includes an extension rod 1601, an extension block 1602, a positioning plate 1603, a stabilizing spring 1604 and a toggle block 1605. The interior of the upper mold 8 and the lower mold 10 is fixed to the extension rod 1601, and the outer surface of the extension rod 1601 is slidably connected to the extension block 1602.

[0038] In general, by pushing the toggle block 1605 so that the extension block 1602 loses connection with the lower forming block 11 and the upper forming block 9, the lower forming block 11 and the upper forming block 9 can be removed from the interior of the lower mold 10 and the upper mold 8 without the need to disassemble the lower mold 10 and the upper mold 8, thereby effectively improving the overall practicality.

[0039] The electrical components appearing in the text are all electrically connected to the controller and the power supply. The control method of the present invention is controlled by the controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field. In addition, the present invention is mainly used to protect mechanical devices, so the control method and circuit connection are no longer explained in detail in the present invention.

[0040] The working principle of the above embodiment is:

[0041] By starting the drive motor 4, the drive rod 5 can be rotated, so that the push rod 6, which is restricted from rotating by the push plate 7, moves due to the extrusion of the thread, so that the push plate 7 pushes the upper mold 8 to move downward and close the mold with the lower mold 10. At this time, the injection molding tank body 12 is started, and the raw material can be injected into the upper molding block 9 and the lower molding block 11 under high pressure. Driven by the water pump, the cooling water will circulate inside the cooling assembly, which can cool the lower molding block 11. After the molding is completed, the drive motor 4 is reversed to reset the upper mold 8, and the cylinder 13 is started to move the ejection block 14 and the ejector pin 15 upward to eject the molded part. When the specification needs to be changed, by pushing the toggle block 1605 to move, the extension block 1602 can be moved together, so that the extension block 1602 loses the connection with the lower molding block 11 and the upper molding block 9. At this time, the lower molding block 11 and the upper molding block 9 can be taken out without disassembling the lower mold 10 and the upper mold 8, thereby effectively improving the processing efficiency and making the overall more practical.
