Description

Technical Field

[0001] This utility model relates to the field of mold equipment technology, and in particular to a non-standard vacuum adsorption film labeling mold. Background Technology

[0002] Molds are used to cast plastic products. To add patterns to existing plastic products, printing and other methods are required, which is a relatively complicated process. Moreover, it is even more difficult to print patterns on some special-shaped plastic products. Therefore, a new type of mold is needed to solve this problem. Utility Model Content

[0003] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of this invention may be realized and obtained by means of the structures particularly pointed out in the description and other accompanying drawings.

[0004] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a non-standard vacuum adsorption membrane labeling mold.

[0005] To achieve the above objectives, the technical solution of this utility model is: an irregularly shaped vacuum adsorption film labeling mold, comprising a punch and a die, one end of the punch and the die being rotatably connected to each other, an air cavity being provided below the die cavity of the die, a plurality of air holes communicating with the air cavity being provided at the bottom of the die, an air passage being provided in the die to connect the air cavity with the outside, a control mechanism for controlling the communication state of the air passage being connected to the air passage, and a mold locking mechanism being provided between the punch and the die.

[0006] By adopting the above technical solution, air can be extracted from the air cavity below the mold cavity through a control mechanism and air passages. During molding, a patterned film is placed on top of the mold cavity, and then the air in the air cavity is extracted through the control mechanism. The air cavity is connected to the mold cavity through air holes. At this time, the air between the film and the bottom of the mold cavity is extracted, and the film will adhere to the bottom of the mold cavity, forming the same shape as the bottom of the mold cavity. Then, molten plastic is poured into the mold cavity to form a plastic product with a patterned film. This method can easily give plastic products various patterns and improve processing efficiency.

[0007] Preferably, the concave mold is rotatably connected to a pressure plate. This invention utilizes the pressure plate to fix the film, preventing it from shifting during vacuuming.

[0008] Preferably, a locking mechanism is provided between the pressing plate and the die. This invention utilizes the locking mechanism to fix the pressing plate, ensuring that the pressing plate remains fixed to the film.

[0009] Preferably, the locking mechanism includes a snap-fit ​​component and a rotating component. The snap-fit ​​component has a semi-circular groove, and the rotating component has a semi-cylinder for engaging with the semi-circular groove. The rotating component includes a rotating shaft fixed to both ends of the semi-cylinder and a handle, with the handle fixedly connected to one of the rotating shafts. This invention allows the handle to drive the rotating shaft to rotate, causing the semi-cylinder to rotate into the semi-circular groove of the snap-fit ​​component. At this point, the pressure plate or punch can be fixed on the die.

[0010] Preferably, the control mechanism includes a housing and a valve core. The housing is fixedly connected to the die and communicates with the air passage. The valve core is threadedly connected to the housing. This invention utilizes the threaded connection between the valve core and the housing, allowing the position of the valve core to be changed by rotating it, thereby controlling the opening and closing of the air passage.

[0011] Preferably, the bottom of the outer casing is provided with a first conical surface, and the end of the valve core is provided with a second conical surface with the same slope as the first conical surface. The valve core has a T-shaped channel, with the vertical portion of the T-shaped channel facing the portion of the valve core that has the second conical surface. This utility model utilizes the T-shaped channel and the first and second conical surfaces to achieve the opening and closing of the air passage. When the first and second conical surfaces are in contact with each other, the T-shaped channel is closed; when the first and second conical surfaces are separated, the T-shaped channel is open. This action is achieved through the rotation of the valve core and the threaded connection between the valve core and the outer casing.

[0012] Preferably, the valve core is fixedly connected to a handle. This invention utilizes the handle to facilitate the rotation of the valve core.

[0013] Preferably, the valve core is fixed with an air nozzle. This invention allows the valve core to connect to the air hose of an external air pump.

[0014] Preferably, a plurality of the air holes are arranged along the bottom edge of the mold cavity of the concave mold. This arrangement allows air to be uniformly extracted from all parts of the mold cavity, enabling the film to be repositioned and adhered to the bottom of the mold cavity.

[0015] Preferably, the die has a boss along the edge of the die cavity. This invention utilizes the boss to maintain tension on the film after the pressure plate presses down, resulting in a smooth film surface and ensuring a seal between the film and the die cavity.

[0016] In summary, the beneficial effects of this utility model are:

[0017] 1. During molding, a patterned film is placed over the die. Then, air is extracted from the air chamber through a control mechanism. The air chamber is connected to the die cavity through air holes. At this time, the air between the film and the bottom of the die cavity is extracted, and the film will adhere to the bottom of the die cavity, forming the same shape as the bottom of the die cavity. Then, molten plastic is poured into the die cavity to form a plastic product with a patterned film. This method can easily create various patterns on the surface of plastic products and improve processing efficiency.

[0018] 2. The boss can continue to tension the film after the pressure plate is pressed down, so that the film surface is flat and the sealing between the film and the mold cavity is guaranteed.

[0034] like Figure 1-4 As shown, an irregularly shaped vacuum adsorption film labeling mold includes a punch 1 and a die 2. One end of the punch 1 and the die 2 are rotatably connected to each other. An air cavity 3 is provided below the mold cavity of the die 2. Several air holes 4 connected to the air cavity 3 are provided at the bottom of the die 2. An air passage 5 is provided in the die 2 to connect the air cavity 3 with the outside. The air passage 5 is connected to a control mechanism 6 for controlling the connection state of the air passage 5. A mold locking mechanism is provided between the punch 1 and the die 2.

[0035] By adopting the above technical solution, air can be extracted from the air cavity 3 below the mold cavity 2 through the control mechanism 6 and the air channel 5. During molding, a patterned film is covered above the mold cavity 2, and then the air in the air cavity 3 is extracted through the control mechanism 6. The air cavity 3 is connected to the mold cavity 2 through the air hole 4. At this time, the air between the film and the bottom of the mold cavity is extracted, and the film will be adsorbed on the bottom of the mold cavity, forming the same shape as the bottom of the mold cavity. Then, molten plastic is poured into the mold cavity to form a plastic product with a patterned film. In this way, it is convenient to make plastic products have various patterns and improve processing efficiency.

[0036] The die 2 is rotatably connected to the pressure plate 7. The pressure plate 7 can fix the film, so that the film will not shift during the vacuuming process.

[0037] A clamping mechanism is provided between the pressing plate 7 and the die 2. The clamping mechanism can fix the pressing plate 7, so that the pressing plate 7 keeps the film fixed.

[0038] The mold-locking mechanism includes a snap-fit ​​component 8 and a rotating component 9. The snap-fit ​​component 8 has a semi-circular groove 12, and the rotating component 9 has a semi-cylinder 10 for engaging with the semi-circular groove 12. The rotating component 9 includes a rotating shaft 11 fixed to both ends of the semi-cylinder 10 and a handle, with the handle fixedly connected to one of the rotating shafts 11. The handle can drive the rotating shaft 11 to rotate, causing the semi-cylinder 10 to rotate into the semi-circular groove 12 of the snap-fit ​​component 8. At this time, the pressure plate 7 or the punch 1 can be fixed on the die 2.

[0039] The control mechanism 6 includes a housing 13 and a valve core 14. The housing 13 is fixedly connected to the die 2 and is connected to the air passage 5. The valve core 14 is threadedly connected to the housing 13. By rotating the valve core 14, the position of the valve core 14 can be changed, thereby controlling the opening and closing of the air passage 5.

[0040] The bottom of the outer casing 13 is provided with a conical surface one, and the end of the valve core 14 is provided with a conical surface two with the same slope as the conical surface one. The valve core 14 has a T-shaped channel 15, with the vertical part of the T-shaped channel 15 facing the part of the valve core 14 with the conical surface two. The opening and closing of the air passage 5 is achieved by using the T-shaped channel 15 and the conical surfaces one and two. When the conical surfaces one and two are in contact with each other, the T-shaped channel 15 is closed. When the conical surfaces one and two are separated, the T-shaped channel 15 is open. This action is achieved by the rotation of the valve core 14 and the threaded connection between the valve core 14 and the outer casing 13.

[0041] The valve core 14 is fixedly connected to a handle 16. The handle 16 facilitates the rotation of the valve core 14.

[0042] The valve core 14 is fixed with an air nozzle 17. This allows the valve core 14 to connect to the air hose on an external air pump.

[0043] Several air holes 4 are provided along the bottom edge of the mold cavity 2. This arrangement allows air to be drawn out evenly throughout the mold cavity, enabling the film to be alternately adhered to the bottom of the mold cavity.

[0044] The die 2 has a boss 18 along the edge of the die cavity. The boss 18 can continue to tension the film after the pressure plate 7 is pressed down, so that the film surface is flat and the sealing between the film and the die cavity is guaranteed.

[0045] It should be noted that many specific details have been set forth in the above description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.
