Description

Technical Field

[0001] This invention relates to the field of slush molding machines, and more particularly to a slush molding machine with high-efficiency cooling. Background Technology

[0002] A slush molding machine is a type of equipment used to produce slush molded toys. During the production process, PVC liquid is poured into the mold of the slush molding machine. The slush molding machine rotates the mold and heats it evenly, causing the PVC liquid to solidify and adhere to the edge of the mold. Nowadays, most of the hands of human-shaped mannequins are also shaped using a slush molding machine.

[0003] For example, Chinese patent CN110154338A discloses a design of a fully automatic auxiliary system for a slush molding machine, which uses automated process equipment to replace all processes other than the slush molding furnace that are currently still manually completed by operators (such as: pulling the slush molding mold out of the slush molding furnace, cooling the slush molding mold, removing the cover, taking out the slush part, slurry injection, sealing the cover, and sending the mold to be slush molded into the slush molding furnace, etc.).

[0004] The above-mentioned solution involves cooling the slush mold by air after it is pulled out of the slush furnace, which results in low cooling efficiency and needs further improvement. Summary of the Invention

[0005] To further improve cooling efficiency, this application provides a high-efficiency cooling slush molding machine.

[0006] This application provides a high-efficiency cooling slush molding machine, which adopts the following technical solution:

[0007] A high-efficiency cooling slush molding machine includes a machine body, which includes a worktable and a slush molding furnace. A frame and a water-cooling tank are arranged on one side of the machine body. A vertically arranged drive cylinder is arranged on the frame. The piston rod end of the drive cylinder is provided with a placement plate for placing slush molding molds. The drive cylinder drives the placement plate to move up and down inside the water-cooling tank. The side wall of the water-cooling tank has a double layer. A liquid storage part is provided on the bottom wall of the water-cooling tank. The liquid storage part is hollow to form a liquid storage cavity. A push rod extends from the bottom of the placement plate and extends into the liquid storage cavity. The end of the push rod is provided with a movable block that is vertically slidably connected to the liquid storage cavity. A connecting pipe communicating with the double layer is provided at the bottom of the liquid storage cavity. A cooling pipe is arranged inside the liquid storage cavity.

[0008] Optionally, the placement plate is rotatably connected to the end of the piston rod, the bottom of the movable block is provided with a linkage groove, the bottom of the liquid storage part is provided with a drive motor, the output shaft of the drive motor passes into the liquid storage cavity and the end is provided with a linkage block for circumferential linkage with the linkage groove.

[0009] Optionally, an air nozzle is provided at the top opening of the water-cooled tank, and the air nozzle is positioned facing the placement tray inside the water-cooled tank.

[0010] Optionally, the inner wall of the water-cooled tank is provided with an inner sleeve that is rotatably connected to it in the circumference. The air nozzle is connected to the inner sleeve and is evenly distributed around the circumference of the inner sleeve. A linkage structure is provided between the inner sleeve and the placement plate to link the two. The vertical movement of the placement plate links the circumferential rotation of the inner sleeve.

[0011] Optionally, the linkage structure includes a protrusion and a sloping groove. The protrusion protrudes from one side of the placement plate, and the sloping groove is disposed on the inner wall of the inner sleeve. The two ends of the sloping groove penetrate the upper and lower end faces of the inner sleeve to form an outlet.

[0012] Optionally, the placement tray includes a tray body and a connecting frame. The connecting frame is a square frame and fixed to the tray body. The connecting frame includes a top horizontal bar and a middle vertical bar. Two vertical bars are symmetrically arranged and are located on the sides of the tray body respectively. The horizontal bar is used to connect to the end of the piston rod of the drive cylinder.

[0013] Optionally, the disc body is grid-shaped and its surface has multiple drainage holes.

[0014] Optionally, the bottom of the water-cooled tank is provided with a drain hole and a drain pipe is connected thereto, and the top of the water-cooled tank is connected with a water inlet pipe. Both the water inlet pipe and the drain pipe are equipped with shut-off valves.

[0015] In summary, this application includes at least one of the following beneficial technical effects:

[0016] 1. After the slush mold is heated in the slush furnace, it is placed on the placement plate and then immersed in the water-cooling tank for direct cooling. Water cooling is faster than air cooling. Moreover, the water-cooling tank has a jacket. During the descent of the placement plate, the movable block pushes the cooling liquid in the storage chamber into the jacket, which can further cool the water-cooling tank and improve the cooling efficiency. It can also lower the water temperature in the water-cooling tank, allowing the water in the water-cooling tank to better maintain a low temperature.

[0017] 2. The air nozzle is designed to blow away any water adhering to the placement tray back into the water cooling tank after the tray rises, reducing water waste and avoiding the need for frequent cleaning of a large amount of water remaining on the workbench. This helps to keep the workbench cleaner. In addition, the inner sleeve can rotate synchronously during the rise of the placement tray to drive the air nozzle to adjust its position, making the air blowing area more comprehensive.

[0018] 3. When the placement tray is immersed in the water-cooling tank, the drive motor at the bottom can be used to rotate it. This allows the slush mold on the placement tray to come into more comprehensive and even contact with the water, improving the cooling effect. In addition, this can also stir the water in the water-cooling tank, promoting heat dissipation to a certain extent. Attached Figure Description

[0024] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0025] This application discloses a high-efficiency cooling slush molding machine.

[0026] like Figure 1 and Figure 2 As shown, a high-efficiency cooling slush molding machine includes a machine body 1, which includes a workbench 2 and a slush molding furnace 3. The slush molding furnace 3 has an openable door 4. A frame 5 and a water-cooling tank 6 are provided on one side of the workbench 2. The water-cooling tank 6 is placed on the frame 5, and a placement tray 7 for placing slush molding molds is provided inside the water-cooling tank 6. In this way, the slush molding molds are first placed in the slush molding furnace 3 for heating. After heating, they are moved from the workbench 2 to the placement tray 7 and then immersed in the water in the water-cooling tank 6 to achieve water cooling and achieve rapid cooling.

[0027] like Figure 2As shown, a vertical drive cylinder 8 is installed at the top of the frame 5. The piston rod end of the drive cylinder 8 is connected to the placement plate 7 to drive it to rise and fall vertically so as to immerse the slush mold placed on the placement plate 7 into water for cooling. The placement plate 7 includes a plate body 9 and a connecting frame. The plate body 9 is a circular mesh with multiple drainage holes. So that when the plate body 9 is driven to rise after cooling is completed, the water can flow directly back into the water cooling tank 6 from the drainage holes. The connecting frame includes a horizontal bar 10 at the top and a vertical bar 11 in the middle. Two vertical bars 11 are symmetrically arranged and are located at the edges of the plate body 9. The horizontal bar 10 is horizontally arranged and connected to the two vertical bars 11 at both ends. This makes the middle of the plate body 9 an open area, which is convenient for the placement and removal of the slush mold and is less likely to cause interference.

[0028] like Figure 2 As shown, a liquid storage section 12 is connected to the bottom of the water-cooled tank 6. The interior of the liquid storage section 12 is hollow, forming a liquid storage cavity 13 for storing coolant. A movable block 14 is vertically slidably connected inside the liquid storage cavity 13. A push rod 15 is connected to the movable block 14. The push rod 15 is vertically positioned, with one end extending into the water-cooled tank 6 and fixed to the center of the plate 9. At the same time, a jacket 16 is provided in both the side wall and bottom wall of the water-cooled tank 6. A connecting pipe 17 is provided at the bottom of the liquid storage cavity 13. The connecting pipe 17 is symmetrically arranged on both sides of the liquid storage section 12. One end of the connecting pipe 17 is connected to the liquid storage cavity 13, and the other end is connected to the jacket 16. In this way, when the slush mold is placed on the placement plate 7, the driving cylinder 8 drives the placement plate 7 to descend and immerse it in the water-cooled tank 6, thus synchronously driving the liquid storage section 12. The movable block 14 is moved downward, thereby pressing the cooling liquid in the storage chamber 13 into the interlayer 16 of the water-cooled tank 6, achieving further cooling of the water-cooled tank 6, improving the cooling effect and efficiency of the water-cooled tank 6, and also keeping the water in the water-cooled tank 6 at a low temperature for continuous use. Moreover, during the downward movement of the movable block 14, the coolant in the storage chamber 13 is pressed out and simultaneously provides a certain buffering effect on the movable block 14. In addition, a refrigeration pipe 30 is provided at the bottom of the storage chamber 13. When the placement plate 7 rises back to its original position, the coolant in the interlayer 16 flows back into the storage chamber 13 under its own gravity. The refrigeration pipe 30 can continuously cool the coolant, thereby keeping the coolant stably at a low temperature and in a good cooling state.

[0029] like Figure 2As shown, in this embodiment, the connecting frame is rotatably connected to the piston rod end of the driving cylinder 8 and axially linked, that is, the placement plate 7 and the connecting frame can rotate circumferentially around the piston rod. A driving motor 18 is fixedly installed at the bottom of the liquid storage section 12. The output shaft of the driving motor 18 passes into the liquid storage cavity 13 and a linkage block 19 for circumferential linkage is provided at the top. At the same time, a linkage groove 20 that is compatible with the linkage block 19 is opened at the center of the bottom wall of the movable block 14. The linkage groove 20 can be square in shape. In this way, after the placement plate 7 is lowered into place, when the entire slush mold is immersed in the cold water of the water cooling tank 6, the linkage groove 20 of the movable block 14 and the linkage block 19 cooperate to achieve circumferential linkage. The movable block 14 is disc-shaped. At this time, the driving motor 18 can be used to drive the entire placement plate 7 to rotate, so that the slush mold can be further rotated when immersed in water to improve the cooling efficiency and uniformity.

[0030] like Figure 2 As shown, an inner sleeve 21 is provided on the inner wall of the opening of the water-cooled tank 6 and is rotatably connected to it. An air nozzle 22 is provided on the top of the inner sleeve 21. The air nozzle 22 is connected to a high-pressure air source and is evenly distributed around the inner sleeve 21. The air blowing direction of the air nozzle 22 is towards the slush mold on the placement plate 7. After the slush mold is placed in the water-cooled tank 6 and cooled, the drive cylinder 8 drives the placement plate 7 to move upward, so that the slush mold is removed from the cooling water of the water-cooled tank 6. The slush mold on the placement plate 7 is at the opening of the water-cooled tank 6. The air nozzle 22 blows air towards the slush mold, so that the water adhering to the slush mold is blown off and flows back into the water-cooled tank 6. This avoids the situation where a large amount of water remains on the slush mold and wets the workbench 2, and also achieves the purpose of saving water resources.

[0031] like Figure 2 and Figure 3As shown, a linkage structure is provided between the inner sleeve 21 and the placement tray 7, which includes a protrusion 23 and a slanted groove 24. The protrusion 23 is located on one side of the tray 9 and is slidably connected in the slanted groove 24. The slanted groove 24 is formed in the inner wall of the inner sleeve 21, and its two ends penetrate the top and bottom walls of the inner sleeve 21 to form an outlet. The outlet has a flared part to facilitate the entry of the protrusion 23. A guide rod 26 is provided on the side wall of the push rod 15 located inside the water-cooled tank 6, and a guide bar 27 is provided on the inner wall of the water-cooled tank 6. The end of the guide rod 26 is vertically slidably connected to the guide bar 27, and the guide rod 26 can slide from the top of the guide bar 27. The lower two ends slide out, so that during the descent of the placement tray 7, the protrusion 23 slides from the outlet into the inclined groove 24 and moves along the inclined groove 24. At this time, the guide rod 26 and the guide bar 27 cooperate to restrict the rotation of the placement tray 7, thereby driving the inner sleeve 21 to rotate well, so that the air nozzle 22 can blow away the moisture on the slush mold more comprehensively from multiple directions. When the protrusion 23 slides out of the inclined groove 24, the guide rod 26 and the guide bar 27 disengage. At this time, the circumferential rotation of the placement tray 7 is not restricted and can be driven to rotate by the drive motor 18. In this embodiment, the protrusion 23 and the guide bar 27 are staggered to avoid vertical interference.

[0032] like Figure 1 and Figure 2 As shown, a drain pipe 28 is provided on the bottom wall of the water-cooled tank 6, and the drain pipe 28 is connected to the inside of the water-cooled tank 6. At the same time, a water inlet pipe 29 is provided above the opening of the water-cooled tank 6. Both the water inlet pipe 29 and the drain pipe 28 are equipped with shut-off valves. When it is necessary to drain and replace the water in the water-cooled tank 6, the water can be drained through the drain pipe 28, and then new cooling water can be introduced through the water inlet pipe 29. The water inlet pipe 29 can also be used to replenish water to the water-cooled tank 6 under normal circumstances.

[0033] The working principle of this embodiment is as follows: First, the raw material is injected into the slush mold and then placed in the slush furnace 3 for heating and molding. After heating, the slush mold is placed on the placement plate 7. The drive cylinder 8 drives the placement plate 7 to descend, immersing the slush mold in the water-cooling tank 6. During this process, the movable block 14 presses down, causing the cooling liquid in the liquid storage chamber 13 to flow into the interlayer 16. Subsequently, the movable block 14 is linked with the drive motor 18 in a circumferential manner, and the drive motor 18 drives the placement plate 7 to rotate to achieve a better cooling effect. After cooling is completed, the drive cylinder 8 drives the placement platform to rise back to its original position, and the cooling liquid in the interlayer 16 flows back into the cooling chamber and is cooled by the cooling pipe 30. During the rise of the placement plate 7, the inner sleeve 21 rotates, causing the air nozzle 22 to rotate. The air nozzle 22 blows off the moisture on the slush mold. Then, the slush mold is moved to the worktable 2 and the molded product can be taken out.

[0034] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
