Description

Technical Field

[0001] This utility model relates to the field of vacuum forming technology, and more specifically, to a molding device for vacuum forming of vacuum trays. Background Technology

[0002] Vacuum forming is a plastic processing technology. Its main principle is to heat a flat, rigid plastic sheet until it softens, then use vacuum to adhere it to the surface of a mold, and finally cool it to form the desired shape. The molding device used for vacuum forming of blister trays is a key piece of equipment in the vacuum forming process, and its design and performance directly affect the quality and production efficiency of the blister trays.

[0003] Traditional molding devices for thermoforming blister trays have the following shortcomings: Cooling and setting after molding is a crucial step in the thermoforming process. However, traditional cooling methods mostly rely on natural cooling, which is time-consuming because demolding can only be performed after the product has fully set. Prolonged cooling not only extends the production cycle but also affects molding efficiency, making it difficult to achieve expected production volumes. Therefore, shortening the cooling time is an urgent problem to solve in order to improve production efficiency. Thus, improvements are needed. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a molding device for thermoforming blister trays, which has the advantage of being easy to use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a molding device for thermoforming blister trays, comprising a base, a square groove inside the base, a square plate movably installed inside the square groove, a support leg fixedly installed below the base, and sliding grooves extending into the square groove on both sides above the base. Connecting platforms extending above the sliding grooves are fixedly installed above both ends of the square plate, a connecting shaft movably installed above the connecting platform, a placement plate fixedly installed above the connecting shaft, a mold movably installed above the placement plate, a connecting rod fixedly installed above the base, a top cover fixedly installed above the connecting rod, and a fan fixedly installed inside the bottom of the top cover, the fan corresponding to the mold.

[0007] As a preferred embodiment of this utility model, a servo motor is fixedly installed below the base, and the output end of the servo motor is fixedly connected to the bottom side of the disc.

[0008] As a preferred embodiment of this utility model, the connecting platform has a vertical groove inside, a circular plate is movably installed inside the vertical groove, and the bottom end of the connecting shaft is fixedly connected to the top of the circular plate.

[0010] As a preferred embodiment of this utility model, a fixing clamp is provided at the bottom of the top cover, and a groove is fixedly installed on the outer side of the fixing clamp.

[0011] In a preferred embodiment of this invention, the distance between the fixing fixture and the fan corresponds to the diameter of the disc, and the mold corresponds to the fixing fixture.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model uses a cylinder to push the placement plate upward, which in turn moves the mold upward into the fixed fixture, thus performing vacuum forming on the mold. Then, the servo motor is started to move the mold below the fan, at which point the fan is activated to cool the mold.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 5 As shown, this utility model provides a molding device for thermoforming blister trays, including a base 1, a square groove 27 inside the base 1, a square plate 8 movably installed inside the square groove 27, a support leg 2 fixedly installed below the base 1, and sliding grooves 20 extending into the square groove 27 on both sides of the upper part of the base 1. Connecting platforms 10 extending above the sliding grooves 20 are fixedly installed above both ends of the square plate 8. A connecting shaft 13 is movably installed above the connecting platform 10. A placement plate 14 is fixedly installed above the connecting shaft 13. A mold 15 is movably installed above the placement plate 14. A connecting rod 3 is fixedly installed above the base 1. A top cover 4 is fixedly installed above the connecting rod 3. A fan 26 is fixedly installed inside the lower part of the top cover 4. The fan 26 corresponds to the mold 15.

[0023] The mold 15 is placed above the placement plate 14, and then the plastic sheet is installed inside the groove 25 and heated. After heating, the cylinder 18 is started, which pushes the placement plate 14 upward, causing the placement plate 14 to move the mold 15 upward into the fixed fixture 24, thereby performing vacuum forming on the mold 15. After vacuum forming is completed, the cylinder 18 moves the mold 15 back to its original position, and then the servo motor 5 is started, which drives the disc 6 to rotate. The disc 6 rotates and moves the mold 15 forward through the square plate 8, moving the mold 15 to the area below the fan 26. At this time, the fan 26 is started to cool the mold 15.

[0024] The cylinder 18 pushes the placement plate 14 upward, causing the placement plate 14 to move the mold 15 upward into the fixed fixture 24, thereby performing vacuum forming on the mold 15. Then, the servo motor 5 is started to move the mold 15 below the fan 26. At this time, the fan 26 is started to cool the mold 15. Compared with the traditional molding device for vacuum forming of blister trays, this molding device for vacuum forming of blister trays uses the fan 26 to cool the mold 15, thereby accelerating the cooling efficiency of the mold 15 and facilitating subsequent processing.

[0025] The square groove 27 has a disc 6 rotatably mounted inside it. A round block 7 is fixedly mounted above the front end of the disc 6. A rectangular groove 9 is opened below the square plate 8. The round block 7 is located inside the rectangular groove 9. Limiting grooves 21 are opened on both sides of the square groove 27. Mounting plates 22 located inside the limiting grooves 21 are fixedly mounted on both sides of the square plate 8. Rollers 23 are rotatably mounted between the inner sides of the mounting plates 22.

[0026] Start the servo motor 5, which drives the disc 6 to rotate. The disc 6 drives the block 7 to move in a circular motion around the outside of the disc 6. The block 7 moves left and right inside the rectangular groove 9, which drives the square plate 8 to move back and forth. This causes the roller 23 to roll inside the limiting groove 21 to limit the square plate 8. The square plate 8 drives the connecting table 10 to move inside the slide 20, thereby transporting the mold 15 from the fixed fixture 24 to below the fan 26.

[0027] By activating the servo motor 5, the servo motor 5 drives the disc 6 to rotate, thereby causing the roller 23 to roll inside the limiting groove 21 to limit the square plate 8. The square plate 8 then drives the connecting table 10 to move inside the slide 20, thereby transporting the mold 15 from the fixed clamp 24 to below the fan 26. Compared with the traditional molding device for thermoforming blister trays, this molding device for thermoforming blister trays uses the rotation of the disc 6 to drive the mold 15 to move back and forth between the fixed clamp 24 and the fan 26, thus facilitating the thermoforming operation of the mold 15.

[0028] A servo motor 5 is fixedly installed below the base 1, and the output end of the servo motor 5 is fixedly connected to the bottom side of the disc 6.

[0029] Start the servo motor 5, which drives the disc 6 to rotate. The disc 6 drives the block 7 to move in a circle around the outside of the disc 6, so that the block 7 moves left and right inside the rectangular groove 9, which in turn drives the square plate 8 to move back and forth.

[0030] The connecting platform 10 has a vertical groove 11 inside, and a circular plate 12 is movably installed inside the vertical groove 11. The bottom end of the connecting shaft 13 is fixedly connected to the top of the circular plate 12.

[0031] The cylinder 18 pushes the placement plate 14 upward, and the placement plate 14 drives the connecting shaft 13 upward, which in turn drives the circular plate 12 upward, thus limiting the placement plate 14.

[0032] A connecting block 16 is fixedly installed on the inner side of the connecting platform 10, a long plate 17 is fixedly installed above the connecting block 16, a cylinder 18 is fixedly installed below the long plate 17, a telescopic rod 19 is fixedly installed above the cylinder 18, and the telescopic rod 19 is fixedly connected to the lower part of the placement plate 14.

[0033] Start cylinder 18 to move the placement plate 14 upward, and the placement plate 14 will move the mold 15 upward into the fixed fixture 24 for vacuum forming.

[0034] The bottom of the top cover 4 is provided with a fixing clamp 24, and a groove 25 is fixedly installed on the outside of the fixing clamp 24.

[0035] The plastic sheet is installed inside the groove 25, and the groove 25 heats and fixes the plastic sheet, thereby performing the thermoforming operation.

[0036] The distance between the fixing fixture 24 and the fan 26 corresponds to the diameter of the disc 6, and the mold 15 corresponds to the fixing fixture 24.

[0037] The rotating disc 6 drives the mold 15 to move back and forth under the fixed clamp 24 and the fan 26, thus facilitating the vacuum forming operation of the mold 15.

[0038] Working principle and usage process of this utility model:

[0039] The mold 15 is placed above the placement plate 14, and then the plastic sheet is installed inside the groove 25 and heated. After heating, the cylinder 18 is started, which pushes the placement plate 14 upward, causing the placement plate 14 to move the mold 15 upward into the fixed fixture 24, thereby performing vacuum forming on the mold 15. After vacuum forming is completed, the cylinder 18 moves the mold 15 back to its original position, and then the servo motor 5 is started, which drives the disc 6 to rotate. The disc 6 rotates and moves the mold 15 forward through the square plate 8, moving the mold 15 to the area below the fan 26. At this time, the fan 26 is started to cool the mold 15.

[0040] Start the servo motor 5, which drives the disc 6 to rotate. The disc 6 drives the block 7 to move in a circular motion around the outside of the disc 6. The block 7 moves left and right inside the rectangular groove 9, which drives the square plate 8 to move back and forth. This causes the roller 23 to roll inside the limiting groove 21 to limit the square plate 8. The square plate 8 drives the connecting table 10 to move inside the slide 20, thereby transporting the mold 15 from the fixed fixture 24 to below the fan 26.
