Description

Technical Field

[0001] The utility model relates to the field of blister molding, in particular to an adjusting device for positive and negative pressure blister molding and negative pressure blister molding. Background Art

[0002] Blister forming is a production process widely used in industries such as packaging, electronics, automotive, and medical. This process involves heating a plastic sheet to soften it, then applying vacuum or positive pressure to form it onto a mold. Depending on the production requirements, the blister forming process can be categorized as either positive pressure or negative pressure.

[0003] In positive-pressure blister molding, air is forced through channels beneath the mold, pushing the heated plastic sheet toward the mold and forming it. This method is suitable for products with complex shapes and can effectively improve production efficiency. In contrast, negative-pressure blister molding creates negative pressure within the mold, allowing the external air pressure to draw the plastic sheet into the mold. This method is generally suitable for simpler shapes and can achieve higher molding precision.

[0004] However, in actual use, due to the diversity of processed products, the mold needs to be replaced frequently. However, traditional molds are generally installed and fixed with bolts. Tools are required for disassembly and installation, and the threaded holes need to be aligned during installation.

[0037] Reference Figure 1 、 Figure 3 、 Figure 4 The support assembly also includes a positioning plate 63, and an electric telescopic rod 62 is provided on the lower surface of the positioning plate 63. The electric telescopic rod 62 is a prior art and can be implemented by technicians in this field. Since it is a prior art, it will not be described in detail in this case. The lower surface of the positioning plate 63 is fixedly connected to the upper surface of the slide bar 64, and the bottom end of the electric telescopic rod 62 is fixedly connected to the upper surface of the support ring 61.

[0038] Reference Figure 4 、 Figure 5 、 Figure 6When the locking cam 75 is in the closed position, the locking cam 78 is in the closed position, and the block 71 is fixed on the lower surface of the sliding rod 64, and the block 71 is inserted into the inner wall of the slot 701. When the block 71 is inserted, the lower surface of the block 71 squeezes the upper surface of the limit block 74. The rear end of the upper surface of the limit block 74 is set as an inclined surface. When the inclined surface is squeezed, the limit block 74 moves forward, and the limit block 74 is inserted into the inner wall of the limit groove 702, which can limit the block 71 so that the block 71 and the mold 9 are connected together. The limit block 74 passes through and is slidably connected to the rear surface of the connecting block 72. One end of the limit spring 73 is fixedly connected to the front surface of the limit block 74, and the other end of the limit spring 73 The end is fixedly connected to the inner wall of the front side of the connecting block 72. When the limit block 74 moves forward, it will squeeze the limit spring 73 to generate a reaction force. The other end of the compression spring 82 is fixedly connected to the inner wall of the bottom end of the mold 9. The circular plate 81 is slidably connected to the inner wall of the mold 9. When the circular plate 81 moves downward, it will squeeze the compression spring 82 to generate a reaction force. The shift block 83 passes through and is slidably connected to the lower surface of the mold 9. The moving rod 85 is slidably connected to the inner wall of the slide groove 801. The slide groove 801 is opened in an inclined shape. When the guide plate 84 moves longitudinally, it will drive the slide groove 801 to squeeze the moving rod 85, thereby driving the connecting block 72 to move.

[0039] Working principle: When using this device, first install the mold 9 on the device. During installation, align the slot 701 with the block 71 and move the mold 9 upward. When the mold 9 moves upward, the block 71 will be plugged into the slot 701, and the block 71 will squeeze the inclined surface of the limit block 74, so that the limit block 74 moves forward to release the blockage. The limit block 74 moving forward will squeeze the limit spring 73 to generate a reaction force. When the block 71 and the slot 701 are plugged in, the limit block 74 will be aligned with the limit slot 702, and the limit block 74 will not be blocked. At this time, the limit block 74 will be plugged into the limit slot 702 under the push of the reaction force of the limit spring 73 to limit the block 71. At this time, the installation of the mold 9 is completed.

[0040] Then start the electric telescopic rod 62 to change the distance between the positioning plate 63 and the support ring 61. Since the position of the support ring 61 is fixed, the positioning plate 63 will move longitudinally, thereby driving the slide rod 64, the block 71 and the mold 9 to move longitudinally, so that the mold 9 is in a centered state, which is convenient for the subsequent positive and negative pressure blister system 2 to blister mold the workpiece on the mold 9.

[0041] During use, if the mold 9 needs to be disassembled, replaced or cleaned, the shift block 83 is pressed downward to drive the return plate 81 to move downward. The downward moving return plate 81 will squeeze the compression spring 82 to generate a reaction force, and will drive the guide plate 84 to move downward. The downward moving guide plate 84 will drive the slide groove 801 to move, and the slide groove 801 will squeeze the moving rod 85 and then drive the connecting block 72 to move. The moving connecting block 72 will drive the limit spring 73 and the limit block 74 to move, and the limit block 74 will disengage from the limit groove 702 to release the limit on the card block 71. At this time, the mold 9 can be moved downward to disengage from the card block 71 to complete the disassembly, and then the shift block 83 is released. The reaction force of the compression spring 82 will push the return plate 81, the shift block 83, and the guide plate 84 to recover, and then the new mold 9 can be installed.

[0042] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
