The lifting mechanism 2 includes a cylinder 21 fixedly installed on the upper end of the frame 1. A controller 7 is installed on the frame 1, and the controller 7 is electrically connected to the cylinder 21. A telescopic rod 22 is connected to the output end of the cylinder 21, and the free end of the telescopic rod 22 is fixedly connected to a lifting plate 23. Vertical plates 24 are symmetrically arranged on the frame 1, and the lifting plate 23 moves vertically up and down along the two vertical plates 24. The effect achieved by the above components is that the controller 7 can start the cylinder 21, and the cylinder 21 drives the lifting plate 23 to move vertically up and down through the telescopic rod 22; the two vertical plates 24 can maintain the stability of the vertical movement of the lifting plate 23.

[0030] like Figures 1-7 As shown in this embodiment: the lifting mechanism 2 is provided with an upper mold 3, and the frame 1 is equipped with a lower mold 4. The lower mold 4 is located directly below the upper mold 3. The upper mold 3 is installed on the lifting plate 23. The upper mold 3 includes a pressure plate 31 fixedly installed on the bottom surface of the lifting plate 23. The lower mold 4 has a mold cavity 41 in the center. The pressure plate 31 corresponds to and matches the mold cavity 41. An injection tube 32 is provided in the pressure plate 31 and the lifting plate 23. The injection tube 32 passes through the pressure plate 31 and the lifting plate 23. The free end of the injection tube 32 is connected to an injection connector 33. The effect achieved by the above components is that the pressure plate 31 descends vertically with the lifting plate 23 until it is inserted into the mold cavity 41. Then, material can be introduced into the injection tube 32 through the injection connector 33 and then enter the mold cavity 41 for molding.

[0031] like Figures 1-7 As shown in this embodiment: the frame 1 has two movable cavities 11 on both sides, the two movable cavities 11 are located on both sides of the lifting plate 23, and the lifting plate 23 has serrated blocks 25 located in the movable cavities 11 on both sides; the effect achieved by the above components is that the serrated blocks 25 move vertically up and down in the movable cavities 11 along with the lifting plate 23.

[0032] like Figures 1-7As shown in this embodiment: Locking mechanisms 6 are provided on both sides of the frame 1. The locking mechanism 6 includes a movable plate 63 that moves along the movable cavity 11. The two movable plates 63 have toothed grooves 64 on their sides near the sawtooth block 25. The toothed grooves 64 match the sawtooth block 25. Push rods 62 are provided on the sides of the two movable plates 63 that are far apart from each other. The push rods 62 extend out of the movable cavity 11 and are fixedly connected to the output end of the electric push rod 61. The electric push rod 61 is fixedly installed on the side of the frame 1. The frame 1 has an installation cavity 12 that is perpendicular to the two movable cavities 11. The controller 7 is electrically connected to the electric push rod 61. The effect achieved by the above components is that when the lifting plate 23 moves to the appropriate position, the controller 7 starts the electric push rod 61. The electric push rod 61 drives the movable plate 63 to move along the movable cavity 11 through the push rod 62 until the sawtooth block 25 engages with the toothed groove 64. At this time, the locking mechanism 6 can fix the position of the lifting plate 23, thereby stabilizing the upper mold 3.

[0033] like Figures 1-7 As shown in this embodiment: the lifting plate 23 is also provided with a cooling mechanism 5. The cooling mechanism 5 includes four cooling inserts 51 fixedly installed at the bottom of the lifting plate 23. The cooling inserts 51 are rectangularly distributed and closely attached to each other. The lower mold 4 is provided with slots 42 for the four cooling inserts 51 to be inserted. The bottom of the four cooling inserts 51 is provided with blades 58, which are V-shaped. The effect achieved by the above components is that when the pressure plate 31 is inserted into the mold cavity 41, the four cooling inserts 51 are inserted into the slots 42. The setting of the blades 58 facilitates the insertion of the four cooling inserts 51 into the mold cavity 41.

[0034] like Figures 1-7 As shown in this embodiment: Four cooling inserts 51 have inner tubes 52 and expansion tubes 53 on their opposite sides. Two inner tubes 52 are provided and connected to both ends of the expansion tubes 53. The other ends of the two inner tubes 52 are respectively connected to an inlet pipe 54 and an outlet pipe 56. The inlet pipe 54 and outlet pipe 56 are located on the lifting plate 23. The free end of the inlet pipe 54 is connected to an inlet connector 55, and the free end of the outlet pipe 56 is connected to an outlet connector 57. The effect achieved by the above components is that the inlet connector 55 and outlet connector 57 are respectively connected to the external cooling system. The external cooling system introduces coolant into the inlet pipe 54 through the inlet connector 55. The coolant enters the inner pipe 52 through the inlet pipe 54, and then enters the expansion pipe 53 to cool the outer wall of the lower mold 4, thereby achieving rapid cooling of the cage. Then, the coolant enters the outlet pipe 56 through another inner pipe, and finally flows back to the external cooling system through the outlet connector 57. The four cooling inserts 51 are equipped with four sets of inner pipes 52 and expansion pipes 53, so that the four outer walls of the lower mold 4 can be cooled simultaneously, thereby achieving rapid cooling of the cage.

[0035] like Figures 1-7As shown in this embodiment: the slot 42 has an expansion cavity 43 in the direction close to the mold cavity 41. The height of the expansion cavity 43 is less than that of the slot 42. The expansion tube 53 is S-shaped and its height is less than that of the cooling insert 51. The expansion cavity 43 corresponds to and matches the expansion tube 53. The effect achieved by the above components is that after the coolant enters the expansion tube 53, it can quickly expand into the expansion cavity 43, increasing the contact area between the coolant and the outer wall of the lower mold 4, and enhancing the cooling effect on the outer wall of the lower mold 4. The S-shaped distribution of the expansion tube 53 further increases the contact area with the outer wall of the lower mold 4, enhancing the cooling effect on the outer wall of the lower mold 4.

[0036] The working principle of this utility model is as follows: First, the electric push rod 61 is started by the controller 7. The electric push rod 61 drives the moving plate 63 to move along the moving cavity 11 through the push rod 62 until the serrated block 25 separates from the tooth groove 64. Then, the electric push rod 61 is turned off and the cylinder 21 is turned on. The cylinder 21 drives the lifting plate 23 to descend vertically through the telescopic rod 22. The lifting plate 23 drives the pressure plate 31 and the four cooling inserts 51 to descend vertically until the pressure plate 31 is inserted into the mold cavity 41 and the four cooling inserts 51 are inserted into the slots 42. Then, the injection connector 3... Material is introduced into injection tube 32 and then into mold cavity 41 for molding. Then, the external cooling system introduces coolant into injection pipe 54 through injection connector 55. The coolant enters inner tube 52 through injection pipe 54, then enters expansion tube 53, and quickly expands into expansion cavity 43 to cool the outer wall of lower mold 4, thereby achieving rapid cooling of the cage. Then, the coolant enters outlet pipe 56 through another inner tube, and finally flows back to external cooling system through outlet connector 57. Through the above process, rapid molding of the cage can be achieved.
