Description

Technical Field

[0001] This utility model belongs to the technical field of vacuum forming equipment, specifically relating to a high-efficiency vacuum forming machine. Background Technology

[0002] Vacuum forming machines, also known as thermoforming machines, are used to vacuum-form heated and plasticized thermoplastic sheets such as PVC, PE, PP, PET, and HIPS into various shapes of high-end packaging boxes, frames, and other products. Utilizing the vacuum suction generated by a vacuum pump, heated and softened thermoplastic sheets such as PVC and PET are vacuum-formed into various shapes of vacuum covers, blister trays, and other products through molds. Currently, there is no pre-positioning structure for vacuum forming materials, resulting in lower finished product quality. Therefore, it is crucial to develop a high-efficiency vacuum forming machine that overcomes these shortcomings. Utility Model Content

[0004] The vacuum forming material clamping structure includes a base, on which a recess is provided, and the vacuum forming mold structure is installed in the recess.

[0005] The thermoforming material heating structure includes a bracket and a heating block fixed on the bracket. The thermoforming material clamping structure also includes a clamping block connected to the bracket by a spring, which pre-compresses the thermoforming material when the heating block is pressed down.

[0006] The heating block has an upward-facing groove, the sidewall of the groove is inclined, and a plurality of vent holes are provided on the inner wall of the recess. The inner wall of the heating block has a channel connecting the vent holes.

[0007] The vacuum forming mold structure includes a mold block, on which vacuum forming holes and blow forming holes are provided. A heating wire is wound around the outside of the mold, and a cooling water channel is provided inside the mold.

[0008] As a preferred embodiment, an air compressor connected to the blow molding hole and a vacuum pump connected to the suction molding hole are installed in the recess. The blow molding hole is connected to the air compressor via a connecting hose, and the suction molding hole is connected to the vacuum pump via a connecting hose.

[0009] As a preferred embodiment, hot air is introduced into the channel.

[0010] As a preferred embodiment, the system further includes a first electric lifting rod, the end of which is fixedly connected to a bracket to control the vertical movement of the bracket. It also includes a second electric lifting rod fixed to the recess, the end of which is fixed to a vacuum forming mold structure.

[0011] Compared with the prior art, the advantages of this utility model are as follows: This utility model has a simple structure. It can position the vacuum forming material during preheating, then lower the heating block, and after heating, the heating block rises without releasing the positioning of the vacuum forming material. Then the mold block rises, and the heating wire of the mold block works to provide heat to ensure the plasticity of the vacuum forming material. Then the vacuum forming hole is formed. After completion, cooling water can be introduced to achieve shaping. Then air is blown through the blow forming hole to achieve demolding, and at this time the mold block falls. This utility model can reduce misalignment, increase the yield, and increase the efficiency of the vacuum forming machine through the pre-positioning operation. Attached Figure Description

The thermoforming material clamping structure also includes a clamping block 23 connected to the bracket 21 by a spring 24. When the heating block 22 presses down, it pre-compresses the thermoforming material.

[0027] The heating block 22 has an upward groove 25, the sidewall of the groove 25 is inclined, the inner wall of the recess 11 is provided with a plurality of vent holes 26, and the inner wall of the heating block 22 is provided with a channel 27 communicating with the vent holes 26.

[0028] The vacuum forming mold structure includes a mold block 31, on which vacuum forming holes 32 and blow forming holes 33 are provided. A heating wire is wound around the outside of the mold, and a cooling water channel is provided inside the mold. The mold is an existing structure with heating wire and cooling water channel, so it is not shown in the figure.

[0029] As a preferred embodiment, an air compressor 35 communicating with the blow molding hole 33 and a vacuum pump 34 communicating with the suction molding hole 32 are installed in the recess 11.

[0032] Compared with the prior art, the advantages of this utility model are: the utility model has a simple structure, and it can position the thermoforming material during preheating, such as... Figure 2 As shown; then the heating block 22 is lowered, as... Figure 3 As shown, and after heating is complete; as Figure 4 As shown, the heating block 22 rises, but it does not release the positioning of the thermoforming material; as Figure 5 As shown, the mold block 31 then rises, at which point the heating wire of the mold block 31 operates, providing heat to ensure the plasticity of the vacuum forming material. Then, the vacuum forming hole 32 forms the material. After completion, cooling water can be introduced to achieve shaping. Subsequently, air is blown through the blow forming hole 33 to achieve demolding, and at this time, the mold block 31 descends. This invention, through pre-positioning operation, can reduce misalignment, increase the yield rate, and increase the efficiency of the vacuum forming machine.

[0033] After completing the above steps, the first electric lifting rod 41 continues to rise, so that the clamping block 23 can release the restriction on the blister material and take out the formed blister material.
