[0002] Blister molds are widely used in the manufacture of plastic packaging, daily necessities, product shells and other fields. They can be used to produce various plastic products such as shells, trays, blister boxes, etc.

[0003] Some plastic products have special shapes. For example, the top of the side wall of the plastic product has a stepped flange protruding from the inner side wall, and some plastic products have a through hole in the middle of the side wall. It is very difficult to use the existing vacuum forming mold to form the plastic product through one-time demoulding during the vacuum forming process. If the injection mold is used, the mold cost is not only high, but also the shape structure of the plastic product is difficult to achieve. Utility Model Content

[0004] The purpose of the utility model is to overcome the above-mentioned deficiencies in the prior art and provide a thick-sheet vacuum plastic-absorbing mold.

[0006] Two first separation slide blocks, the first separation slide blocks are arranged on the top of the mold body, and the two first separation slide blocks are arranged opposite to each other;

[0007] A first driving device, the first driving device can drive the two first separation sliders to move toward each other so that the side portions of the first separation sliders protrude from the inner wall of the mold cavity of the mold body, or to move oppositely so that the side portions of the first separation sliders do not protrude from the inner wall of the mold cavity of the mold body;

[0008] Two second separation slides, the second separation slides are arranged on the top of the mold body, the two second separation slides are arranged opposite to each other, and the side portions of the two first separation slides and the side portions of the two second separation slides can jointly enclose an opening at the top of the mold body; and

[0009] The second driving device can drive the two second separation sliders to move toward each other so that the side portions of the second separation sliders protrude from the inner wall of the mold cavity of the mold body, or to move oppositely so that the side portions of the second separation sliders do not protrude from the inner wall of the mold cavity of the mold body.

[0010] The utility model discloses a thick sheet vacuum blister mold. Before blister molding, under the driving action of a first driving device, two first separation sliders move toward each other so that the side parts of the first separation sliders protrude from the inner wall of the mold cavity of the mold body. Under the driving action of a second driving device, two second separation sliders move toward each other so that the side parts of the second separation sliders protrude from the inner wall of the mold cavity of the mold body. The side parts of the first separation sliders and the side parts of the second separation sliders protruding from the inner wall of the mold cavity of the mold body provide support for the molding of the step-shaped flanging on the plastic product. After the heated and softened thick sheet is covered on the top of the mold body, it is vacuum-adsorbed. After cooling and molding, the side parts of the first separation sliders and the side parts of the second separation sliders protruding from the inner wall of the mold cavity of the mold body are The side of the second separation slider can form a step-shaped flange on the side wall of the plastic product. When demolding is required, under the driving action of the first driving device, the two first separation sliders move in opposite directions so that the side of the first separation slider does not protrude from the inner wall of the mold cavity of the mold body. Under the driving action of the second driving device, the two second separation sliders move in opposite directions so that the side of the second separation slider does not protrude from the inner wall of the mold cavity of the mold body. At this time, the plastic product with the step-shaped flange can be smoothly separated from the mold body. The thick sheet vacuum suction mold of the utility model has a relatively simple structure and low cost. It can produce plastic products with special shapes, and the appearance structure of the plastic products can meet the production requirements.

[0011] Furthermore, the number of the first driving devices is two, and the two first driving devices respectively drive the two first separation sliders to move so that the side portions of the first separation sliders protrude from the inner wall of the mold cavity of the mold body or do not protrude from the inner wall of the mold cavity of the mold body.

[0012] The first driving device comprises a first cylinder and a first slide rail. The first slide rail is arranged on the base and located at the side of the mold body. The first cylinder drives the first separation sliding block to move along the first slide rail.

[0013] Therefore, the two first separation slide blocks are driven independently, which is convenient for assembly. The movement directions of the two first separation slide blocks are opposite. The first slide rail can ensure that the first separation slide blocks can move smoothly on the top of the mold body.

[0014] Furthermore, it also includes a first slider, the first separation slider includes a first separation part and a first mounting part that are integrally connected, the first separation part is located at the top of the mold body, the first separation part is located at the side of the mold body, the first slider is arranged at the bottom of the first mounting part, the first slider is slidably arranged on the first slide rail, and the first cylinder drives the first mounting part to move along the first slide rail so that the end of the first separation part protrudes from the inner wall of the mold cavity of the mold body or does not protrude from the inner wall of the mold cavity of the mold body.

[0015] Therefore, the first separation slider can move smoothly along the first slide rail through the first slider. The design of the first separation part and the first mounting part can enable the first separation slider to reasonably utilize the space on the side of the mold body, so that the thickness of the first separation part will not be too thick and is adapted to the style of the stepped flange on the plastic product.

[0016] Furthermore, it also includes an oblique mold and a first driving block, the end of the first driving block is arranged on the first mounting portion, the side of the first driving block is provided with an oblique groove, one end of the oblique mold is provided with an oblique buckle adapted to the oblique groove, the oblique buckle is slidably arranged in the oblique groove, and the first driving block can drive the oblique mold to move so that the other end of the oblique mold extends from the inner wall of the mold cavity of the mold body or retracts into the inner wall of the mold cavity of the mold body.

[0017] Therefore, before vacuum forming, under the driving action of the first driving device, the first mounting portion drives the first driving block to move, and the first driving block can drive the oblique mold to move obliquely so that the other end of the oblique mold extends from the inner wall of the mold cavity of the mold body, and the end of the oblique mold protruding from the inner wall of the mold cavity of the mold body provides avoidance for the forming of the through hole on the inner wall of the plastic product. When demolding is required, under the driving action of the first driving device, the first mounting portion drives the first driving block to move in the opposite direction, and the first driving block can drive the oblique mold to move obliquely so that the other end of the oblique mold retracts from the inner wall of the mold cavity of the mold body.

[0020] Furthermore, a partition protrusion protruding from the end surface of the first separation portion is provided at the end of the first separation portion, and the two partition protrusions on the two first separation sliding blocks are arranged opposite to each other.

[0021] Therefore, plastic product A and plastic product B can be formed by vacuum forming in the mold body at the same time. The mold cavity for making plastic product A is located on one side of the line connecting the two partition protrusions, and the mold cavity for making plastic product B is located on the other side of the line connecting the two partition protrusions.

[0022] Furthermore, the number of the second driving devices is two, and the two second driving devices respectively drive the two second separation sliders to move so that the side portions of the second separation sliders protrude from the inner wall of the mold cavity of the mold body or do not protrude from the inner wall of the mold cavity of the mold body.

[0023] The second driving device includes a second cylinder, a second driving block, a connecting block and a second slide rail.

The second cylinder can drive the second driving block to move up and down, the second driving block can drive the connecting block to move horizontally, and the connecting block can drive the second separation slider to move along the second slide rail.

[0024] Therefore, when the second cylinder drives the second driving block to move up and down, since the second driving block and the connecting block are connected by the structure of the inclined clamping block and the inclined buckle groove, the second driving block can drive the connecting block to move horizontally, and the connecting block drives the second separation slider to move along the second slide rail. The second cylinder can be installed below the side of the mold body, effectively reducing the space occupied by the second cylinder on the side of the mold body, thereby effectively reducing the occupied area of ​​the blister mold. Through the cooperation of the second driving block and the connecting block, the up and down movement of the piston rod of the second cylinder can be converted into horizontal movement of the second separation slider. In addition, the two second separation sliders are driven independently for easy assembly, and the movement directions of the two second separation sliders are opposite. The second slide rail can ensure that the second separation slider can move smoothly on the top of the mold body.

[0025] Furthermore, it also includes a second slider, the second separation slider includes a second separation part and a second mounting part that are integrally connected, the second separation part is located at the top of the mold body, the second mounting part is located at the side of the mold body, the second slider is arranged at the bottom of the second mounting part, the second slider is slidably arranged on the second slide rail, and the second cylinder drives the second mounting part to move along the second slide rail so that the end of the second separation part protrudes from the inner wall of the mold cavity of the mold body or does not protrude from the inner wall of the mold cavity of the mold body.

[0026] Therefore, the second separation slider can move smoothly along the second slide rail through the second slider. The design of the second separation part and the second mounting part can enable the second separation slider to reasonably utilize the space on the side of the mold body, so that the thickness of the second separation part will not be too thick and it can adapt to the style of the stepped flange on the plastic product.

[0027] Furthermore, the second driving block is provided with a second slot with a T-shaped longitudinal section, the end of the piston rod of the second cylinder is provided with a second clamping column, and the end of the piston rod of the second cylinder and the second clamping column are clamped in the second slot.

[0028] Therefore, when assembling the second cylinder and the second driving block, the two can be completely assembled by simply inserting the end of the piston rod of the second cylinder and the second clamping column from the end of the second slot into the second slot, and both assembly and disassembly are very simple.
