Description

Technical Field

[0001] This utility model relates to the field of plastic manufacturing technology, specifically to a plastic product thermoforming device. Background Technology

[0002] Plastic product vacuum forming equipment is a type of equipment used to manufacture vacuum-formed products. The vacuum forming process involves heating a thin sheet of plastic to soften it, then using negative pressure to adhere it to a mold, and finally allowing it to cool and form the desired shape.

[0003] Existing vacuum forming products usually require specialized molds, and the cost of making and maintaining molds is relatively high. If the production volume is not large, the mold cost may not be amortized, increasing the overall production cost. In addition, during the vacuum forming process, the plastic sheet begins to soften after being heated. If there is no proper and continuous heating, the plastic sheet will begin to cool before it is adhered to the mold, resulting in an unsatisfactory vacuum forming effect. In response to the above problems, the inventors proposed a plastic product vacuum forming device to solve the above problems. Utility Model Content

[0004] To address the issue that existing thermoforming products typically require specialized molds, and the cost of manufacturing and maintaining these molds is relatively high, potentially leading to increased overall production costs if production volumes are small, this invention aims to provide a thermoforming device for plastic products. By incorporating a thermoforming assembly, a plastic sheet can be placed between the device base and a heating plate. A motor drives a threaded ring to rotate, which in turn moves an extrusion cylinder, allowing the plastic sheet to adhere to the inner wall of a plastic mold, thus completing the thermoforming process. Furthermore, the design incorporates heating elements and an air inlet groove, allowing air to enter during the thermoforming process and be blown onto the plastic sheet for secondary heating via the heating element.

[0005] To solve the above technical problems, the present invention adopts the following technical solution: a plastic product vacuum forming device, including a device base and a heating flip plate, the heating flip plate rotating outside the device base, and a vacuum forming component fixedly installed outside the heating flip plate, the vacuum forming component including a vacuum forming mold fixing groove, a plastic mold, a vacuum forming air hole and an extrusion suction cylinder;

[0006] The vacuum forming mold fixing groove is located outside the device base, the plastic mold is movable outside the vacuum forming mold fixing groove, the device base has a vacuum forming groove outside, and the extrusion cylinder slides on the inner wall of the vacuum forming groove.

[0007] Preferably, an electric heating element is fixedly installed on the outside of the heating flap, and an air inlet groove is provided on the outside of the heating flap.

[0008] Preferably, the device base is rotatably connected to a rotating shaft, the limiting rod is movable outside the rotating shaft, and the limiting rod is rotatably connected to a rotating rod.

[0009] Preferably, a fitting fixing block is fixedly installed on the outside of the heating flap, and a No. 1 threaded rod is fixedly installed on the outside of the rotating rod. The No. 1 threaded rod is threadedly connected to the rotating shaft, and the fitting fixing block can be fitted with the limiting rod.

[0010] Preferably, a first fixing block is fixedly installed on the outside of the device base, a first motor is fixedly installed on the outside of the first fixing block, a threaded ring is rotatably connected to the outside of the first motor, and a second threaded rod is fixedly installed on the outside of the extrusion suction cylinder, the second threaded rod being threadedly connected to the threaded ring.

[0011] Preferably, a sliding rod is fixedly installed on the outside of the extrusion suction cylinder, and a limiting tube is fixedly installed on the outside of the device base, with the limiting tube slidably connected to the sliding rod.

[0012] Preferably, the vacuum forming vent is formed on the inner wall of the vacuum forming mold fixing groove, and the plastic mold is in communication with the vacuum forming vent.

[0013] Preferably, the number of vacuum forming air holes and the number of extrusion suction cylinders are both multiple sets and arranged in an array.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] In this utility model, by setting a vacuum forming component, a plastic sheet can be placed between the device base and the heating flip plate. A No. 1 motor drives a threaded ring to rotate, and the rotation of the threaded ring drives the extrusion suction cylinder to move, which can adsorb the plastic sheet onto the inner wall of the plastic mold, thus completing the vacuum forming of the plastic product. By placing the plastic sheet between the device base and the heating flip plate, it can be ensured that the plastic sheet remains in the correct position during the heating and adsorption process. This helps to avoid forming problems caused by inaccurate positioning, thereby ensuring the smooth progress of the vacuum forming process. The adsorption process ensures uniform contact of the plastic sheet, reducing the risk of surface defects or irregular forming.

[0016] In this invention, by designing an electric heating element and an air inlet groove, air can be introduced into the plastic product through the air inlet groove during the vacuum forming process. The air is then blown onto the plastic sheet by the electric heating element for secondary heating. This secondary heating ensures that the plastic sheet maintains sufficient softness and plasticity when it is adsorbed onto the inner wall of the mold. This helps the plastic sheet better adapt to the shape of the mold and avoids cracks or deformation during the vacuum forming process. Attached Figure Description

[0027] By adopting the above technical solution, the heating flap 2 has an air inlet groove 12 on its outside, which allows air to enter the plastic product through the air inlet groove 12 during the vacuum forming process, and the air is blown onto the plastic sheet by the heating element 11 for secondary heating.

[0028] The device base 1 is externally rotatably connected to a rotating shaft 6. A limiting rod 7 is movable outside the rotating shaft 6. A rotating rod 8 is externally rotatably connected to the limiting rod 7. A fitting fixing block 10 is fixedly installed externally on the heating flip plate 2. A threaded rod 9 is fixedly installed externally on the rotating rod 8. The threaded rod 9 is threadedly connected to the rotating shaft 6.

[0029] By adopting the above technical solution, the fitting and fixing block 10 and the limiting rod 7 can be fitted together, and the movement of the limiting rod 7 can drive the heating flip plate 2 to be fixed to the device base 1.

[0030] A first fixing block 13 is fixedly installed on the outside of the device base 1. A first motor 14 is fixedly installed on the outside of the first fixing block 13. A threaded ring 15 is rotatably connected to the outside of the first motor 14. A second threaded rod 16 is fixedly installed on the outside of the extrusion suction cylinder 19.

[0033] By adopting the above technical solution, the first sliding rod 18 can be slidably connected to the limiting tube 17, and the limiting tube 17 can be used to limit the first sliding rod 18.

[0034] The vacuum forming vent 5 is opened on the inner wall of the vacuum forming mold fixing groove 3, and the plastic mold 4 is connected to the vacuum forming vent 5.

[0035] By adopting the above technical solution, the plastic mold 4 and the vacuum forming air hole 5 are connected, so that the plastic sheet can be adsorbed onto the inner wall of the plastic mold 4.

At the same time, air can enter from the air inlet groove 12 while the plastic product is being vacuum-formed, and is blown onto the plastic sheet by the heating element 11 for secondary heating. This secondary heating can ensure that the plastic sheet can maintain sufficient softness and plasticity when it is adsorbed onto the inner wall of the mold.
