[0021] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0022] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0024] When in use, the lifting component 4 controls the top mold 3 to move in the vertical direction. After the top mold 3 and the bottom mold 2 are fitted on the surface, molten raw materials are injected into the cavity through the injection channel 31. During the injection molding process, the temperature of the top mold 3 and the bottom mold 2 increases. The guide component 51 and the circulating water flow component 52 cooperate with each other to control the circulation of cooling water between the lower cooling cavity 7 in the bottom mold 2 and the upper cooling cavity 6 in the top mold 3. The upper cooling cavity 6 and the lower cooling cavity 7 can effectively increase the contact area between the cooling water and the bottom mold 2 and the top mold 3, thereby accelerating the cooling and cooling speed of the bottom mold 2 and the top mold 3. While the cooling water circulates, the blowing component 81 and the driving component 82 cooperate with each other to further accelerate the flow speed of the air in the lower cooling cavity 7, thereby accelerating the evaporation of water in the lower cooling cavity 7. The cooling water evaporates and absorbs heat in the lower cooling cavity 7, which can further improve the cooling and cooling effect on the bottom mold 2, thereby accelerating the molding speed of the product in the cavity.

[0025] like Figure 1 , Figure 2As shown, as a preferred embodiment of the present invention, the lifting assembly 4 includes a plurality of groups of threaded rods 41 rotatably installed between the workbench 1 and the top plate 12, the plurality of groups of threaded rods 41 are respectively located on both sides of the top mold 3, and a positioning block 42 is fixedly installed on the side wall of the top mold 3, the positioning block 42 is threadedly connected to the threaded rod 41, a synchronous gear plate 44 is fixedly installed on the surface of the threaded rod 41, and the plurality of groups of synchronous gear plates 44 are commonly connected to a synchronous belt 45, and the top end of a group of threaded rods 41 extends to above the top plate 12 and is connected to a first motor 43.

[0026] When in use, the first motor 43 drives a group of threaded rods 41 to rotate and then drives the synchronous gear plate 44 to rotate. Multiple groups of synchronous gear plates 44 cooperate with the synchronous belt 45 to drive multiple groups of threaded rods 41 to rotate synchronously. Multiple groups of threaded rods 41 cooperate with each other during rotation, which can conveniently control the top mold 3 to move in the vertical direction, and then the height of the top mold 3 can be conveniently adjusted.

[0027] like Figure 1 , Figure 3 , Figure 5 , Figure 6 , Figure 7 As shown, as a preferred embodiment of the present invention, the guide component 51 includes a water storage chamber 511 opened inside the bottom mold 2 and located below the lower cooling chamber 71, and a plurality of groups of lower water guide channels 513 respectively connected to the water storage chamber 511 are opened downward on the surface of the bottom mold 2, and the plurality of groups of lower water guide channels 513 are respectively located on both sides of the water storage chamber 511, and the middle part of the lower water guide channel 513 is connected to the lower cooling chamber 7 through a branch pipe, and a plurality of groups of upper water guide channels 512 respectively connected to the upper cooling chamber 6 are opened upward on the bottom wall of the top mold 3, and the bottom end of the upper water guide channel 512 is relatively distributed with the top end of the lower water guide channel 513, and the side wall of the bottom mold 2 is provided with a water injection pipe 5111 connected to the water storage chamber 511.

[0028] When in use, cooling water is stored in the water storage chamber 511 through the water injection pipe 5111. After the top mold 3 moves downward and fits with the surface of the bottom mold 2, the bottom end of the upper water channel 512 fits with the top end of the lower water channel 513 to form a conductive state. When cooling the bottom mold 2 and the top mold 3, the circulating water flow component 52 pushes the cooling water to move in the water storage chamber 511. The cooling water moves to the lower water channel 513 on one side of the water storage chamber 511. The cooling water further flows in the lower water channel 513 and the upper water channel 512 and can flow to the upper cooling chamber 6 and the lower cooling chamber 7 respectively. The cooling water in the upper cooling chamber 6 and the lower cooling chamber 7 flows back to the water storage chamber 511 from the upper water channel 513 and the lower water channel 513 on the other side. This cycle is repeated, and the cooling water can be controlled to flow continuously in the upper cooling chamber 6 and the lower cooling chamber 7. The cooling water absorbs heat when flowing, and can cool down the bottom mold 2 and the top mold 3.

[0029] like Figure 1 , Figure 3 , Figure 5 , Figure 6 , Figure 7 As shown, as a preferred embodiment of the present invention, the circulating water flow component 52 includes a push plate 521 slidably installed in the water storage chamber 511, and a threaded rod 522 is rotatably installed in the water storage chamber 511. The threaded rod 522 is threadedly connected to the push plate 521, and one end of the threaded rod 522 extends to the outside of the bottom mold 2 and is connected to a second motor 523.

[0030] The cooling water is injected into the water storage chamber 511, and the second motor 523 controls the threaded rod 522 to rotate. The threaded rod 522 pushes the push plate 521 to move in the water storage chamber 511 when rotating. When the push plate 521 moves from one side of the water storage chamber 511 to the other side of the water storage chamber 511, the push plate 521 can easily push the cooling water into the lower water guide channel 513. After the cooling water flows back from the other side of the water storage chamber 511, the second motor 523 controls the threaded rod 522 to rotate in the opposite direction and then controls the push plate 521 to move in the opposite direction. The reciprocating movement of the push plate 521 can control the cooling water to flow back and forth between the upper cooling chamber 6 and the lower cooling chamber 7.

[0031] like Figure 3 , Figure 4 As shown, as a preferred embodiment of the present invention, the blowing assembly 81 includes a plurality of groups of parallel distributed bearing rods 811 rotatably installed in the lower cooling chamber 7, and a plurality of groups of parallel distributed fan blades 812 are arranged on the surface of the bearing rods 811.

[0032] When the push plate 521 moves back and forth in the water storage chamber 511, the driving component 82 controls the load-bearing rod 811 to rotate in the lower cooling chamber 7, and the load-bearing rod 811 drives the fan blades 812 to rotate synchronously. When rotating, the fan blades 812 can accelerate the air flow speed in the lower cooling chamber 7, thereby accelerating the evaporation of water. The heat absorption of water evaporation can further accelerate the cooling effect of the bottom mold 2.

[0033] like Figure 3 , Figure 4 , Figure 7As shown, as a preferred embodiment of the present invention, the driving assembly 82 includes a sliding bar 822 slidably installed in the lower cooling chamber 7 and located below the bearing rod 811, a toothed disc 821 is fixedly installed on the surface of the bearing rod 811, and a rack 823 meshing with the toothed disc 821 is fixedly installed on the surface of the sliding bar 822 through a bracket, and pulling ropes 824 are fixedly installed on the two opposite side walls of the sliding bar 822, and a guide wheel 825 is rotatably installed in the lower water guide channel 513, and the end of the pulling rope 824 away from the sliding bar 822 passes through the lower water guide channel 513 and the guide wheel 825 and further extends into the water storage chamber 511, and the end of the pulling rope 824 located in the water storage chamber 511 is fixedly connected to the side wall of the push plate 521.

[0034] When the push plate 521 moves back and forth in the water storage chamber 511, it cooperates with the pulling ropes 824 on both sides to drive the sliding bar 822 to move back and forth synchronously in the lower cooling chamber 7. The sliding bar 822 drives the rack 823 to move synchronously. When moving, the rack 823 engages with the toothed disc 821 for transmission, which can drive the toothed disc 821 to rotate. The toothed disc 821 drives the load-bearing rod 811 and the fan blades 812 to rotate synchronously.

[0035] like Figure 3 , Figure 5 , Figure 6 As shown, as a preferred embodiment of the present invention, the surface of the bottom mold 2 is provided with an annular sealing groove 9 which is sleeved on the outer side of the lower water guide channel 513, and the bottom wall of the top mold 3 is fixedly mounted with a sealing ring 10 which cooperates with the sealing groove 9.

[0036] After the bottom wall of the top mold 3 is fitted with the surface of the bottom mold 2, the sealing ring 10 is inserted into the sealing groove 9, which can further improve the sealing effect at the joint between the lower water channel 513 and the upper water channel 512, and effectively prevent the seepage of cooling water.

[0037] The working principle of the present invention is: when in use, the first motor 43 drives a group of threaded rods 41 to rotate and then drives the synchronous gear plate 44 to rotate. The multiple groups of synchronous gear plates 44 cooperate with the synchronous belt 45 to drive the multiple groups of threaded rods 41 to rotate synchronously. The multiple groups of threaded rods 41 cooperate with each other during rotation, and can conveniently control the top mold 3 to move in the vertical direction, and then can conveniently adjust the height of the top mold 3. After the top mold 3 and the bottom mold 2 are attached to the surface, the molten raw material is injected into the cavity through the injection channel 31. During the injection molding process, the temperature of the top mold 3 and the bottom mold 2 increases, and the cooling water is stored in the water storage chamber 511 through the water injection pipe 5111. The second motor 523 controls the rotation of the threaded rod 522. The threaded rod 522 pushes the push plate 521 to move in the water storage chamber 511 when rotating. During the process of the push plate 521 moving from one side of the water storage chamber 511 to the other side of the water storage chamber 511, the push plate 521 can conveniently push the cooling water into the lower water guide channel 513. The cooling water further flows in the lower water channel 513 and the upper water channel 512 and then flows into the upper cooling chamber 6 and the lower cooling chamber 7 respectively. The cooling water in the upper cooling chamber 6 and the lower cooling chamber 7 flows back to the water storage chamber 511 from the upper water channel 513 and the lower water channel 513 on the other side. In this way, the cooling water can be controlled to continuously flow in the upper cooling chamber 6 and the lower cooling chamber 7. The cooling water absorbs heat while flowing, and can cool down the bottom mold 2 and the top mold 3.

[0038] When the push plate 521 moves back and forth in the water storage chamber 511, it cooperates with the pulling ropes 824 on both sides, and can drive the sliding bar 822 to move back and forth synchronously in the lower cooling chamber 7. The sliding bar 822 drives the rack 823 to move synchronously. When the rack 823 moves, it meshes with the toothed disc 821 to drive the toothed disc 821 to rotate. The toothed disc 821 drives the bearing rod 811 and the fan blade 812 to rotate synchronously. When the fan blade 812 rotates, it can accelerate the air flow speed in the lower cooling chamber 7, thereby accelerating the evaporation of water. The heat absorption of water evaporation can further accelerate the cooling effect of the bottom mold 2.

[0039] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.
