[0002] In industrial production, various molds and tools are used to obtain the required products by injection molding, blow molding, extrusion, die casting or forging, smelting, stamping and other methods. In short, molds are tools used to make molded objects. Plastic products are an indispensable part of modern life. Most of the plastic molds used more now are thermoplastic products, which are made by injection of plastic molds and are more convenient to produce.

[0003] The process of plastic processing is generally completed by injection molding, and there are many methods of injection molding. Spray molding is a commonly used injection molding method for plastic processing, which can quickly complete plastic processing.

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Example:

[0040] See also Figure 1 , Figure 2 , Figure 7-10The present invention provides a technical solution: a cooling molding device for plastic processing, comprising a fixed frame 1, on which a spraying cylinder 2 and a movable module 4 are movably mounted, and a fixed module 3 is fixedly mounted, and a spraying cavity 24 is arranged in the fixed module 3 and the movable module 4, and the two spraying cavities 24 are symmetrically distributed with each other, and a demoulding component is arranged in the spraying cavity 24, and the plastic particles in the spraying cylinder 2 are spray-molded in the spraying cavity 24, and the demoulding component facilitates the demoulding of the plastic formed inside the spraying cavity 24;

[0041] The demoulding assembly includes a demoulding plate 28, which moves on the injection molding cavity 24 to demould the molded plastic.

[0042] In this embodiment, the demolding assembly also includes a connecting column 29 and a second fixed column 31. A piston plate 27 is fixedly installed on the top of several connecting columns 29. The top of the piston plate 27 is fixedly connected to the demolding plate 28. The connecting column 29 can move up and down to drive the demolding plate 28 to move up and down through the piston plate 27, thereby facilitating the demolding of the molded plastic in the injection molding cavity 24.

[0043] The spray-molding cylinder 2 is connected to the groove 11 through the spray-molding nozzle 6, and sprays the crushed plastic into the spray-molding cavity 24 in the fixed module 3 and the movable module 4. When the plastic particles in the spray-molding cavity 24 form molded plastic under the action of pressure, the push column 39 will be driven to move together when the spray-molding cylinder 2 moves toward the side of the fixed module 3. When the push column 39 moves, it will drive the piston plate 27 to move downward through the second fixed column 31. When the piston plate 27 moves downward, it will also drive the stripper plate 28 to move downward until the stripper plate 28 is flush with the bottom end surface of the spray-molding cavity 24, so as to prevent the stripper plate 28 from causing the spray-molding cavity 24 to be not in a closed state, and to prevent defects in the spray-molded plastic.

[0044] In this embodiment, an adjusting chamber 26 is opened in the fixing module 3, the piston plate 27 is located in the adjusting chamber 26, and the second fixing column 31 is fixedly connected to the inner wall of the adjusting chamber 26 and extends out of the adjusting chamber 26. A second extrusion spring 34 is fixedly installed under the piston plate 27, and the second extrusion spring 34 is sleeved on the outer side of the connecting column 29. The second extrusion spring 34 can drive the stripping plate 28 to extend from the adjusting chamber 26 into the injection molding chamber 24. When the piston plate 27 moves downward, it will squeeze and contract the second extrusion spring 34, thereby providing power for the stripping plate 28 to demold the molded plastic.

[0045] In this embodiment, a connecting seat 32 and a second motor 37 are fixedly installed in the fixed frame 1, and a reciprocating screw 38 is fixedly installed on the output shaft end of the second motor 37. A pushing column 39 is fixedly installed on the reciprocating screw 38. An inclined surface 40 is provided between the pushing column 39 and the second fixed column 31, and the two columns are in contact through the inclined surface 40.

[0046] In this embodiment, a rack column 30 is fixedly installed at the bottom end of the pushing column 39, and a first rotating gear 35 and a second rotating gear 36 are movably installed in the connecting seat 32. The first rotating gear 35 and the second rotating gear 36 are fixedly connected, the rack column 30 is meshedly connected with the first rotating gear 35, and the connecting column 29 is meshedly connected with the second rotating gear 36. When the rack column 30 moves, it will drive the first rotating gear 35 to rotate, and when the first rotating gear 35 rotates, it will drive the second rotating gear 36 to rotate, and when the rack column 30 moves, it will not hinder the movement of the connecting column 29.

[0047] See also Figure 1-Figure 6 The present invention provides a technical solution: in this embodiment, a fixed block 7 is fixedly installed on the fixed frame 1, and a first sliding block 14 is movably installed in the fixed block 7. The first sliding block 14 is connected to the spray-molding cylinder 2, and a storage cylinder 5 is fixedly installed on the spray-molding cylinder 2. The unloading end of the storage cylinder 5 is communicated with the inner cavity of the spray-molding cylinder 2, and the storage cylinder 5 is located at the starting end of the feeding spiral auger rod 13 in the spray-molding cylinder 2. After the plastic particles in the storage cylinder 5 enter the spray-molding cylinder 2, they move to the side of the discharge hole 15 through the feeding spiral auger rod 13, and the plastic particles are crushed to facilitate plastic processing and molding. The crushed plastic particles are more convenient to enter the spray-molding nozzle 6 through the discharge hole 15 to prevent the discharge hole 15 from being blocked.

[0048] In this embodiment, a first motor 10 is fixedly installed on the outer side of the spray-molding cylinder 2, a feed screw auger rod 13 is fixedly installed on the output shaft end of the first motor 10, a discharge hole 15 is located at the end of the feed screw auger rod 13, and a spray-molding nozzle 6 is fixedly installed on the side of the end of the spray-molding cylinder 2 close to the discharge hole 15, and the spray-molding nozzle 6 is connected to the discharge hole 15.

[0049] In this embodiment, the spray nozzle 6 is penetrated by a spray hole 16, a fixed frame 18 is fixedly installed in the spray nozzle 6, and a blocking ball 17 is movably installed inside the spray nozzle 6, the blocking ball 17 is adjacent to the spray hole 16, a first fixed column 19 is fixedly installed in the fixed frame 18, a first extrusion spring 20 is sleeved on the outer side of the first fixed column 19, a second sliding block 21 is movably installed on the outer side of the first fixed column 19, and a connecting rod 22 is fixedly connected to the bottom end of the second sliding block 21, and the connecting rod 22 is fixedly connected to the blocking ball 17. When the blocking ball 17 is stretched open by the shift rod 23, the blocking ball 17 will move away from the spray hole 16 to facilitate the passage of plastic particles in the spray cylinder 2. After the spraying is completed, the blocking ball 17 will return to its original position under the action of the first extrusion spring 20, and block the spray hole 16 again to prevent the plastic particles in the spray cylinder 2 from leaking.

[0050] The telescopic cylinder 12 on the fixed frame 1 is connected to the movable module 4, which can not only enable the movable module 4 to be removed from the fixed module 3 for easy operation and maintenance, but also prevent the formation of a gap between the fixed module 3 and the movable module 4, thereby avoiding leakage of the crushed plastic particles in the injection molding cavity 24, and ensuring the stability and reliability of the production process.

[0051] In this embodiment, a connecting groove 11 matching the spray nozzle 6 is provided in the fixed module 3 and the movable module 4, a shift rod 23 is fixedly installed in the connecting groove 11, and a feed through hole 33 is provided between the shift rod 23 and the inner wall of the connecting groove 11. When the spray tube 2 moves toward the fixed module 3 and the movable module 4, the shift rod 23 will open the material blocking ball 17 in the spray nozzle 6, and the plastic particles in the spray tube 2 can be sprayed into the spray cavity 24 through the spray nozzle 6.

[0052] The transmission structure composed of the second motor 37, the reciprocating screw 38, the pushing column 39, the rack column 30, the first rotating gear 35 and the second rotating gear 36 is used to achieve the precise movement of the spray barrel 2 and the coordinated work of the demoulding components. The structure is compact and the transmission is efficient, which ensures the stable operation of the entire device and the orderly coordination between the various components, and optimizes the process flow of plastic processing cooling molding.

[0053] The design of the storage barrel 5 and the feeding spiral auger rod 13 allows the plastic particles to be crushed after entering the spray barrel 2, and the crushed particles are more convenient to enter the spray nozzle 6 through the discharge hole 15, preventing the discharge hole 15 from being blocked, which is beneficial to plastic processing and molding, and improves molding quality and production continuity.

[0054] In this embodiment, the reciprocating screw 38 is threadedly connected with a connecting block 8, and the side of the connecting block 8 is fixedly connected to the pushing column 39. The connecting block 8 is respectively fixedly connected to the pushing column 39 and the spray-molding cylinder 2, and a sliding through hole 9 matching the connecting block 8 is opened through the fixed frame 1. A cooling channel 25 is opened in the fixed module 3, and water inlet and outlet are set at both ends of the cooling channel 25 to realize the flow of water inside the cooling channel 25, which is convenient for the rapid cooling of the molded plastic in the spray-molding cavity 24 and the demolding of the molded plastic with the stripping plate 28. A telescopic cylinder 12 is also fixedly installed on the fixed frame 1, and the telescopic cylinder 12 is fixedly connected to the movable module 4. The telescopic cylinder 12 can remove the movable module 4 from the fixed module 3. At the same time, the telescopic cylinder 12 can prevent the fixed module 3 and the movable module 4 from having a gap, thereby preventing the leakage of plastic particles after being crushed in the spray-molding cavity 24.

[0055] When the second motor 37 is in operation, the reciprocating screw 38 is driven to rotate. When the reciprocating screw 38 rotates, the pushing column 39 and the connecting block 8 are driven to move simultaneously. When the connecting block 8 moves, the spray-molding cylinder 2 is driven to move toward one side of the fixing module 3. When the pushing column 39 moves, the second fixing column 31 is driven downward through the inclined surface 40. At the same time, the second fixing column 31 drives the piston plate 27 to move downward in the adjusting chamber 26. At the same time, when the piston plate 27 moves downward, it drives the stripping plate 28 to move downward and be flush with the bottom end surface of the spray-molding chamber 24. At this time, the spray-molding nozzle 6 enters the connecting groove 11, and the gear lever 23 opens the blocking ball 17 in the spray-molding nozzle 6. The plastic particles in the spray-molding cylinder 2 can pass through the spray-molding nozzle 6 into the spray-molding chamber 24. The blocking ball 17 will be away from the spray-molding hole 16, which is convenient for the plastic particles in the spray-molding cylinder 2 to pass through. After the spray-molding is completed, the blocking ball 17 will be heavy under the action of the first extrusion spring 20. After the plastic is sprayed, the second motor 37 stops working, and the plastic spraying nozzle 6 is prevented from being blocked by the discharge hole 15. When the plastic is sprayed, the second motor 37 starts to reverse, and the push column 39 and the spraying cylinder 2 are moved in the opposite direction. Under the cooling of the active water flow in the cooling channel 25 and the action of the second extrusion spring 34, the stripping plate 28 will return to the spraying chamber 24, and the telescopic cylinder 12 drives the active module 4 and the fixed module 3 to separate from each other, so that the molded plastic in the spraying chamber 24 can be demoulded, which is convenient for demoulding the molded plastic in the spraying chamber 24.

[0056] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
