Description

Technical Field

[0001] This utility model relates to the field of far-infrared physiotherapy patch processing technology, and more specifically, to an injection molding device for the production of far-infrared physiotherapy patches. Background Technology

[0002] Far-infrared therapy patches are patch-type medical devices that use far-infrared technology to assist in the treatment of diseases. They are usually made of materials such as far-infrared ceramic powder, acrylic pressure-sensitive adhesive, non-woven fabric, and silicone paper. Far-infrared ceramic powder can emit far-infrared rays, which can penetrate deep into the skin and reach tissues and cells in the body, producing certain biological effects, such as stimulating mitochondria in cells, promoting cell metabolism and energy metabolism, and enhancing cell immunity and antioxidant capacity.

[0003] A search revealed that Chinese patent CN219294828U discloses an injection molding device for producing physiotherapy patches. In this invention, a cylinder drives a telescopic rod to move vertically downward, and the telescopic rod drives a pressure plate to move vertically downward. Through the arrangement of the pressure plate and the placement groove, the pressure plate can mold the ointment in the placement groove.

[0004] When the above-mentioned molding device is in use, the motor drives the placement plate to rotate, which in turn drives the ointment in the placement groove to rotate. However, it is difficult to detect the rotation angle of the placement plate. When the rotation angle of the placement plate does not reach the specified range, the pressure plate is not located directly above the placement groove, which will result in molding failure and thus affect production efficiency. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides an injection molding device for the production of far-infrared physiotherapy patches, which aims to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a far-infrared therapy patch injection molding device, comprising a base frame, a U-shaped plate, and two molds. The bottom end of the U-shaped plate is fixedly connected to the base frame, and both molds are located inside the U-shaped plate. A rotating assembly is provided on the base frame. The rotating assembly includes a placement plate, a rotating shaft, a stepper motor, an L-shaped plate, a laser emitter, and two laser receivers. The bottoms of both molds are in contact with the placement plate. The top end of the rotating shaft is fixedly connected to the placement plate, and the rotating shaft is movably connected to the top end of the base frame via a bearing. The output shaft end of the stepper motor is fixedly connected to the rotating shaft, and the stepper motor is fixedly installed at the center of the bottom end inside the base frame. The top end of the L-shaped plate is fixedly connected to the base frame. The laser emitter is fixedly installed on one side of the L-shaped plate, and both laser receivers are located on one side of the laser emitter, and both laser receivers are fixedly installed on the rotating shaft.

[0007] Furthermore, the bottom of the placement tray is fixedly connected to two limiting frames, each of which is movably provided with an insert block, and each of the insert blocks is provided with a locking bolt. The two insert blocks are fixed to the two limiting frames by two locking bolts respectively.

[0008] It can be seen that the above technical solution is designed to facilitate the disassembly and replacement of the mold.

[0009] Furthermore, a first pressure plate is movably mounted on the top of one of the molds, and a first hydraulic cylinder is fixedly connected to the top of the first pressure plate by bolts, and the top of the first hydraulic cylinder is fixedly connected to the U-shaped plate.

[0010] It can be seen that the above technical solution facilitates the disassembly and replacement of the first pressure plate.

[0011] Furthermore, another mold is movably provided with a discharge pipe at its top, and the top end of the discharge pipe is fixedly connected to a storage cylinder, which is fixedly embedded in the top end of the U-shaped plate.

[0012] Furthermore, a valve is fixedly installed on the discharge pipe.

[0013] Furthermore, the top of the storage cylinder is provided with an extrusion assembly, which includes a support plate, a second hydraulic cylinder, and a second pressure plate.

[0014] Furthermore, the bottom end of the support plate is fixedly connected to the U-shaped plate, the top end of the second hydraulic cylinder is fixedly connected to the support plate, and the top end of the second pressure plate is fixed to the second hydraulic cylinder by bolts.

[0015] As can be seen, the above technical solution facilitates the accelerated downward movement of the ointment.

[0016] The technical effects and advantages of this utility model are as follows:

[0017] 1. This utility model uses a stepper motor to drive the rotating shaft and the placement plate to rotate, thereby driving one of the molds to rotate and placing one of the molds at the bottom of the first pressure plate. At the same time, the rotating shaft drives two laser receivers to rotate, and the laser emitter works to emit lasers. When one of the laser receivers receives the laser, it indicates that one of the molds is directly below the first pressure plate. The operation is simple and convenient for detecting the rotation angle of the placement plate.

[0018] 2. This utility model releases the fixation between the mold and the placement plate by rotating the locking bolt away from the limiting frame, allowing the mold to be disassembled and replaced. Rotating the bolt away from the first pressure plate releases the fixation between the first pressure plate and the first hydraulic cylinder, allowing the first pressure plate to be disassembled and replaced. The hydraulic cylinder on the second hydraulic cylinder extends, causing the second pressure plate to move downward. The second pressure plate squeezes the ointment in the storage cylinder, accelerating the downward movement of the ointment. The structure is simple and easy to use. Attached Figure Description

[0027] Refer to the instruction manual appendix Figure 1-5 The far-infrared therapy patch production injection molding device of this embodiment includes a base frame 1, a U-shaped plate 2, and two molds 6. The bottom end of the U-shaped plate 2 is fixedly connected to the base frame 1, and both molds 6 are located inside the U-shaped plate 2. A rotating assembly 5 is provided on the base frame 1. The rotating assembly 5 includes a placement plate 501, a rotating shaft 502, a stepper motor 503, an L-shaped plate 504, a laser emitter 505, and two laser receivers 506. The bottom of both molds 6 is in contact with the placement plate 501, and the top end of the rotating shaft 502 is in contact with the placement plate. 501 is fixedly connected, and the rotating shaft 502 is movably connected to the top of the bottom frame 1 through a bearing. The output shaft end of the stepper motor 503 is fixedly connected to the rotating shaft 502, and the stepper motor 503 is fixedly installed at the center of the bottom of the bottom of the bottom frame 1. The top of the L-shaped plate 504 is fixedly connected to the bottom frame 1. The laser emitter 505 is fixedly installed on one side of the L-shaped plate 504. Two laser receivers 506 are located on one side of the laser emitter 505, and both laser receivers 506 are fixedly installed on the rotating shaft 502.

[0028] Furthermore, two limiting frames 507 are fixedly connected to the bottom of the placement tray 501. Each limiting frame 507 is movably provided with a plug 13, and each plug 13 is provided with a locking bolt 14. The two plugs 13 are fixed to the two limiting frames 507 by the two locking bolts 14 respectively. A first pressure plate 4 is movably provided on the top of one of the molds 6. The top of the first pressure plate 4 is fixedly connected to a first hydraulic cylinder 3 by bolts, and the top of the first hydraulic cylinder 3 is fixedly connected to the U-shaped plate 2.

The operation is simple and convenient for detecting the rotation angle of the placement plate 501.
