Description

Technical Field

[0001] This invention relates to the field of electrotherapy belt processing technology, and more specifically, to a wearable electrotherapy belt and its molding process. Background Technology

[0002] An electrotherapy waist belt is an electronic device that uses electric current to stimulate the waist and abdomen to achieve physiotherapy, rehabilitation, or shaping purposes. There are many types of electrotherapy waist belts on the market. A high-frequency welding machine is a device that uses a high-frequency electric field to make the molecules of plastic materials vibrate and generate heat through friction, thereby achieving welding or fusion. It is mainly used for welding thermoplastic plastics, and is especially suitable for products that require high strength and good sealing, such as health waist belts, knee pads, cushions, and inflatable products. Therefore, electrotherapy waist belts are generally also processed and produced using this type of machine.

[0003] The molds for high-frequency welding machines need to be specially designed according to the shape, size, and material of the product to ensure welding effect and quality. Different products require different molds to achieve the best welding effect. The mold consists of two parts: a base and a top cover. After the base and top cover are combined, they use their strong electrical conductivity to heat-press the belt components held between them, causing the stacked belt components to stick together due to heat pressing. Therefore, each processing operation requires manual stacking of multiple layers of belt components that need to be heat-pressed on the base, and finally merging the top cover with the base. Together, the belt components are clamped and fixed, and then the combined mold is pushed under the hot press for hot pressing. After hot pressing, because the top cover is still hot and the connection between the top cover and the base is tight, the operator needs to use a pry bar to remove the top cover from the base. Then the hot-pressed belt is taken out and the next belt is processed. However, this process of separating the top cover is quite laborious and requires the assistance of a pry bar, which slows down the overall processing efficiency and also requires the operator's skill level, increasing the processing difficulty. Summary of the Invention

[0004] This invention provides a wearable electrotherapy belt and its molding process, solving the technical problem that the mold top cover needs to be pried open in related technologies.

[0005] This invention provides a wearable electrotherapy waist belt and its molding process, including a processing table and a first driving mechanism. The first driving mechanism is fixedly installed on the top of the processing table, and a hot press plate is fixedly connected to the output end of the first driving mechanism. The first driving mechanism is used to drive the hot press plate to move along the height direction of the processing table. A slide is provided on the top of the processing table, and a horizontal driving mechanism is installed on the processing table. The output end of the horizontal driving mechanism is connected to the slide, and the horizontal driving mechanism is used to drive the slide to move along the length direction of the processing table. A second drive mechanism is installed on both sides of the processing table, and the second drive mechanism is located on the side away from the hot press plate. A clamping guide plate is set at the top of the slide table. The clamping guide plate is connected to the output end of the second drive mechanism. The second drive mechanism is used to drive the clamping guide plate to move towards each other along the width direction of the processing table. A mold base is fixedly connected to the middle of the top of the slide table. A positioning groove is opened at the top of the mold base along the height direction of the mold base. A connecting groove is opened at the bottom of the positioning groove. A mold top cover is set on the top of the mold base. A positioning rod is fixedly connected to the bottom of the mold top cover. The mold top cover is slidably connected to the positioning groove through the positioning rod. Clamping grooves are opened on both sides of the mold base along the width direction of the processing table. The clamping grooves are opened along the width direction of the processing table and are connected to the connecting groove. A clamping rod is slidably connected inside the clamping groove. An elastic element is connected to the bottom of the connecting groove. A reset groove is opened on the mold base along the width direction of the processing table. A slider is slidably connected inside the reset groove. The slider is fixedly connected to the clamping rod. A spring is connected between the slider and the wall of the reset groove. One end of the spring is connected to the slider and the other end of the spring is connected to the wall of the reset groove.

[0006] In a preferred embodiment, the hot press plate is rectangular. When the bottom end of the mold top cover is attached to the top end of the mold base, the distance between the top end of the mold top cover and the bottom end of the hot press plate is less than the distance between the top end of the clamping guide plate and the bottom end of the hot press plate. The mold top cover and the mold base have the same shape, and the top end of the mold base is provided with a placement groove. The bottom end of the mold top cover is fixedly connected with a heat-conducting protrusion. The heat-conducting protrusion and the placement groove cooperate with each other to realize the hot pressing operation.

[0007] In a preferred embodiment, the clamping guide plate is rectangular, the diameter of the positioning groove is larger than the diameter of the positioning rod, and both the positioning groove and the positioning rod are cylindrical. The diameter of the connecting groove is the same as the diameter of the positioning rod, and the connecting groove is semi-circular. A semi-circular groove is provided at one end of the clamping rod near the positioning rod, and the diameter of the semi-circular groove is the same as the diameter of the connecting groove and the diameter of the positioning groove.

[0008] In a preferred embodiment, when the elastic element is in its initial state, the bottom end of the positioning rod extends out of the connecting groove. When the spring inside the reset groove is in its initial state, the end of the clamping rod near the positioning rod does not contact the positioning rod.

[0009] In a preferred embodiment, a flip-up bracket is included, which is fixedly connected to one side of the mold top cover. A connecting plate is fixedly connected to one side of the mold base near the flip-up bracket, and a groove is provided on the connecting plate along the height direction of the mold base.

[0010] In a preferred embodiment, a slide rod is fixedly connected to the flip-up card holder, and the flip-up card holder is slidably connected to the inside of the slide groove through the slide rod. A clearance groove is provided on one side of the positioning groove, and the clearance groove is connected to the adjacent positioning groove.

[0011] In a preferred embodiment, two sets of flip-up brackets and connecting plates are provided, and the two flip-up brackets and two connecting plates are symmetrical about the central axis in the width direction of the mold top cover. The length of the clearance groove is greater than the length of the positioning rod, and the width of the clearance groove is less than the diameter of the positioning groove. When the elastic element is in the initial state.

[0012] In a preferred embodiment, the bottom end of the positioning rod is positioned above the bottom end of the clearance groove, and the height of the groove is greater than the height to which the elastic element pushes the positioning rod upward.

[0013] In a preferred embodiment, a limiting top plate is also included. The limiting top plate is fixedly connected to the clamping guide plate on one side near the mold top cover. Limiting plates are fixedly connected to both sides of the mold top cover. When the bottom end of the mold top cover is in contact with the top end of the mold base, the top end of the limiting plate is below the bottom end of the limiting top plate. Both the limiting top plate and the limiting plate are rectangular. When the slide is in a position away from the hot press plate, the limiting plate will not collide with the limiting top plate when the mold top cover moves upward.

[0014] This invention provides a molding process for a wearable electrotherapy belt, comprising the following steps: S1: The belt components are manually stacked inside the placement slot of the mold base; S2: Then slide the mold top cover into the positioning groove through the positioning rod to achieve the docking of the mold top cover and the mold base; S3: Then press down the top cover of the mold and start the second drive mechanism. By reducing the inner diameter of the circular groove formed by the end of the clamping rod and the connecting groove, the positioning rod is fixed. S4: Subsequently, as the horizontal drive mechanism moves downwards towards the hot press plate, the limiting top plate will engage with the limiting plate on the mold top cover to prevent the mold top cover from opening. S5: Subsequently, the hot press plate heat-presses the waist belt component inside the mold top cover and mold base. Then, the horizontal drive mechanism drives the slide away from the hot press plate. Finally, the operator removes the second drive mechanism, flips and opens the mold top cover, takes out the formed waist belt, and puts in a new waist belt component. This cycle is repeated to achieve efficient processing.

[0015] The beneficial effects of this invention are as follows: 1. Due to the design of the elastic element, clamping rod, positioning rod and positioning groove, the present invention optimizes the docking and closing process between the mold top cover and the mold base, effectively avoids misalignment in hot pressing position, reduces the defect rate, ensures product quality stability, and the convenient process of mold docking and clamping positioning greatly improves the efficiency of hot pressing operation. The elastic reset structure enables convenient opening of the mold top cover without the need for additional tools, reduces the difficulty of operation and further improves the overall production efficiency.

[0016] 2. Due to the design of the flip-type card seat, connecting plate, slide groove and slide rod, the present invention optimizes the mold opening and positioning process, greatly shortens the docking time between the mold top cover and the base, significantly improves the overall processing efficiency, and the design of the elastic reset and flip structure makes the opening and reset of the mold top cover smoother and less labor-intensive, reducing the workload of operators.

[0017] 3. Due to the limiting top plate and the limiting plate, the present invention ensures that the mold top cover remains closed throughout the movement and hot pressing operation through a precise limiting and matching mechanism. This effectively avoids jamming caused by the misalignment of the positioning rod, ensuring continuous and smooth hot pressing operation. At the same time, it significantly reduces the frequency of component wear, greatly extends the overall service life of the equipment, and reduces the number of downtime maintenance.

[0029] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, a wearable electrotherapy belt includes a processing table 1 and a first drive mechanism 2. The first drive mechanism 2 is fixedly installed on the top of the processing table 1. A hot plate 21 is fixedly connected to the output end of the first drive mechanism 2. The first drive mechanism 2 is used to drive the hot plate 21 to move along the height direction of the processing table 1. A slide 3 is provided at the top of the processing table 1. A horizontal drive mechanism is installed on the processing table 1. The output end of the horizontal drive mechanism is connected to the slide 3. The horizontal drive mechanism is used to drive the slide 3 to move along the length direction of the processing table 1. A second drive mechanism 4 is installed on both sides of the processing table 1, and the second drive mechanism 4 is located on the side away from the hot press plate 21. A clamping guide plate 41 is provided at the top of the slide table 3. The clamping guide plate 41 is connected to the output end of the second drive mechanism 4. The second drive mechanism 4 is used to drive the clamping guide plate 41 to move towards each other along the width direction of the processing table 1. A mold base 51 is fixedly connected to the middle of the top of the slide table 3. A positioning groove 53 is opened at the top of the mold base 51 along the height direction of the mold base 51. A connecting groove 531 is opened at the bottom of the positioning groove 53. A mold top cover 5 is provided above the mold base 51. A positioning rod 54 is fixedly connected to the bottom of the mold top cover 5. The mold top cover 5 is connected to the positioning rod 54 by a positioning rod 54. Positioning rod 54 is slidably connected inside positioning groove 53. Clamping grooves 52 are provided on both sides of mold base 51 along the width direction of processing table 1. Clamping grooves 52 are provided along the width direction of processing table 1 and are connected to connecting groove 531. Clamping rod 55 is slidably connected inside clamping groove 52. Elastic element 56 is connected to the bottom end of connecting groove 531. Reset groove 57 is provided on mold base 51 along the width direction of processing table 1. Slider is slidably connected inside reset groove 57. Slider is fixedly connected to clamping rod 55. Spring is connected between slider and groove wall of reset groove 57. One end of spring is connected to slider and the other end of spring is connected to groove wall of reset groove 57.

[0031] It should be noted that the first drive mechanism 2, the horizontal drive mechanism, and the second drive mechanism 4 can all be linear drive mechanisms such as cylinders or lead screw assemblies. This is existing technology and will not be elaborated here. The hot press plate 21 is rectangular. When the bottom end of the mold top cover 5 is in contact with the top end of the mold base 51, the distance between the top end of the mold top cover 5 and the bottom end of the hot press plate 21 is less than the distance between the top end of the clamping guide plate 41 and the bottom end of the hot press plate 21. The mold top cover 5 and the mold base 51 have the same shape, and the top end of the mold base 51 has a placement groove. The bottom end of the mold top cover 5 is fixedly connected to a heat-conducting protrusion. The heat-conducting protrusion and the placement groove cooperate with each other to realize the hot pressing operation. The clamping guide plate 41 is rectangular. The diameter of the positioning groove 53 is larger than the diameter of the positioning rod 54, and both the positioning groove 53 and the positioning rod 54 are cylindrical. The diameter of 531 is the same as the diameter of the positioning rod 54, and the connecting groove 531 is semi-circular. A roller is installed on the end of the clamping rod 55 away from the positioning rod 54. A semi-circular groove is opened on the end of the clamping rod 55 near the positioning rod 54, and the diameter of the semi-circular groove is the same as the diameter of the connecting groove 531 and the diameter of the clamping rod 55. The elastic element 56 can be an elastic workpiece such as a spring or a gas spring. This is the prior art and will not be described in detail here. When the elastic element 56 is in the initial state, the bottom end of the positioning rod 54 extends out of the outside of the connecting groove 531. When the spring inside the reset groove 57 is in the initial state, the end of the clamping rod 55 near the positioning rod 54 does not contact the positioning rod 54. In this embodiment, the positioning grooves 53 are respectively distributed at the four corners of the top of the mold base 51, and the positioning rods 54 are respectively distributed at the four corners of the bottom of the mold top cover 5.

[0032] In actual use, the operator stacks the belt components that need to be heat-pressed and fused inside the placement slots on the mold base 51. After stacking, the operator places the mold top cover 5 on top of the mold base 51. During this process, the operator needs to slide several positioning rods 54 into their corresponding positioning slots 53. The sliding connection between the positioning rods 54 and the positioning slots 53 ensures that after the mold top cover 5 and the mold base 51 are fully fitted, the placement slots and the heat-conducting protrusions will not be misaligned, thus ensuring the uniformity of the heat-pressing and fusion position on the belt and preventing misalignment that could lead to defective products. It also provides guidance for the fitting of the mold top cover 5 and the mold base 51. The docking of the positioning rods 54 and the positioning slots 53 also ensures the proper connection between the mold top cover 5 and the mold base 51. The process becomes faster and more precise, thereby improving the efficiency of hot pressing. After the mold top cover 5 and the mold base 51 are connected, there is a gap between the bottom of the mold top cover 5 and the top of the mold base 51 because the bottom of the connecting groove 531 is connected to the elastic element 56. Therefore, the operator must press down on the mold top cover 5 to make the opposite ends of the mold top cover 5 and the mold base 51 close together. After the fit is completed, the operator pushes the clamping guide plate 41 to move towards each other through the second drive mechanism 4, thereby pushing the clamping rod 55 to move. At that time, the clamping rod 55 will slide inside the clamping groove 52 until the end of the clamping rod 55 near the positioning rod 54 forms a circular groove with the connecting groove 531 to fix the positioning rod 54 and prevent the elastic element 56 from pushing the positioning rod 54 out of the positioning groove 53 after the operator leaves the mold top cover 5.After the positioning rod 54 is clamped, the operator drives the slide table 3 to move along its length at the top of the processing table 1 using the horizontal drive mechanism. During this process, the end of the clamping rod 55 away from the positioning rod 54 will slide along one side of the clamping guide plate 41. Since a roller is installed on the end of the clamping rod 55 near the clamping guide plate 41, the end of the clamping rod 55 will not come into contact with the clamping guide plate 41 during the sliding process, until the mold top cover 5 and the mold base 51 move to below the hot press plate 21. Then, the operator moves the hot press plate 21 downwards using the first drive mechanism 2 until the bottom end of the hot press plate 21 is in contact with the top end of the mold top cover 5, and conducts heat to the placement groove and the heat-conducting protrusion, so that the position where the waist belt component is pressed by the heat-conducting protrusion is welded, and the multi-layer waist belt components can be bonded together. After the hot pressing is completed, the hot press plate 21 is... Reset the slide 3 and move it to a position away from the hot press plate 21. Then, reset the second drive mechanism 4. At this time, the clamping rod 55 will be pushed by the spring inside the reset groove 57 and move away from the mold base 51. The diameter of the circular groove formed by the clamping rod 55 and the connecting groove 531 will increase, so that the positioning rod 54 loses its clamping limit and is pushed upward by the elastic element 56. This will also drive the mold top cover 5, which is fixedly connected to the positioning rod 54, to move upward. At this time, the operator only needs to move the mold top cover 5 away from the mold base 51. This eliminates the need to pry up the mold top cover 5 with a pry bar after hot pressing is completed. The mold top cover 5 can be opened directly, improving the overall efficiency of the hot pressing operation and reducing the overall difficulty of the hot pressing operation.

[0033] In the above embodiment, by setting an elastic element 56 at the bottom of the positioning groove 53, the positioning rod 54 is pushed out of the positioning groove 53 using the elastic element 56, making the opening of the mold top cover 5 faster. This avoids the need for a pry bar to assist in opening the mold in the traditional way. However, after the mold top cover 5 is opened, the operator still needs to move the mold top cover 5 to another location. After the belt component inside the placement groove is placed, the mold top cover 5 also needs to be moved back and reconnected to the mold base 51. This makes the mold material changing process lengthy and complicated. To solve the above problems, in another embodiment of the present invention, a flip-down bracket 571 is included. The flip-down bracket 571 is fixedly connected to one side of the mold top cover 5. A connecting plate 572 is fixedly connected to one side of the mold base 51 near the flip-down bracket 571. A sliding groove 573 is provided on the connecting plate 572 along the height direction of the mold base 51. A sliding rod 574 is fixedly connected to the flip-down bracket 571. The flip-down bracket 571 is slidably connected to the inside of the sliding groove 573 through the sliding rod 574. A clearance groove 576 is provided on one side of the positioning groove 53. The clearance groove 576 is connected to the adjacent positioning groove 53.

[0034] It should be added that, such as Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, two sets of flip-down card holders 571 and connecting plates 572 are provided, and the two flip-down card holders 571 and the two connecting plates 572 are symmetrical about the central axis of the width direction of the mold top cover 5. The length of the clearance groove 576 is greater than the length of the positioning rod 54, and the width of the clearance groove 576 is less than the diameter of the positioning groove 53. When the elastic member 56 is in the initial state, the bottom end of the positioning rod 54 is above the bottom end of the clearance groove 576. In this embodiment, the bottom end of the positioning rod 54 is arc-shaped, and the height of the slide groove 573 is greater than the height to which the elastic member 56 pushes the positioning rod 54 to rise.

[0035] In actual use, after hot pressing is completed and the second drive mechanism 4 resets, as the clamping rod 55 moves away from the connecting groove 531, the inner diameter of the circular groove expands, thus losing its clamping limit on the positioning rod 54. At this time, the elastic element 56 pushes the positioning rod 54 upward, creating a gap between the mold top cover 5 and the mold base 51. Simultaneously, the sliding rod 574 slides inside the sliding groove 573. At this time, the operator can flip the mold top cover 5 upward. During this process, the mold top cover 5 will flip around the sliding rod 574 as the center. During this process, the bottom end of the positioning rod 54 will sweep across the relief groove 576 until the positioning rod 54 is completely disengaged from the relief groove 576. During this process, the positioning rod 54 will not be affected by the flipping and will not be separated from the positioning groove 531. The contact between the 3 groove walls makes the mold top cover 5 rotate more smoothly. At the same time, the rotating bracket 571 and the connecting plate 572 can ensure that there is a connection between the mold top cover 5 and the mold base 51. After the bottom of the mold top cover 5 is separated from the top of the mold base 51, the mold top cover 5 is on one side of the mold base 51. By rotating the mold top cover 5, it can be closed with the mold base 51 again, making the closing process between the mold top cover 5 and the mold base 51 more convenient and faster. The docking process between the mold top cover 5 and the mold base 51 is directly achieved by rotating, which simplifies the docking process between the mold top cover 5 and the mold base 51, improves the overall processing efficiency, and also makes the processing more labor-saving.

[0036] In the above embodiment, by setting the flip-type card holder 571 and connecting plate 572, the separation between the mold top cover 5 and the mold base 51 can be achieved by flipping. This makes the closing process between the mold top cover 5 and the mold base 51 simpler and faster. However, in the above process, the positioning rod 54 is fixed by the circular groove formed by the end of the clamping rod 55 and the connecting groove 531. Since the minimum inner diameter of the circular groove is fixed, it is impossible to increase the clamping force of the circular groove by continuously pushing the clamping rod 55. Therefore, during the movement of the slide table 3, with the slight shaking of the slide table 3, the positioning rod 54 may disengage from the circular groove. As a result, when the mold top cover 5 is below the hot press plate 21, it is in a state of being pushed up by the elastic member 56. Since the diameter of the positioning groove 53 is larger than that of the positioning rod 54 after the positioning rod 54 disengages from the positioning groove 53, under the drive of the horizontal drive mechanism... The mold top cover 5 will shake slightly, so the positioning rod 54, which is disengaged from the positioning groove 53, will move horizontally inside the positioning groove 53. This may cause the positioning rod 54 to be misaligned with the groove opening of the connecting groove 531. During the subsequent pressing of the hot press plate 21, the positioning rod 54 may not be able to enter the connecting groove 531 due to the misalignment between the end of the positioning rod 54 and the groove opening of the connecting groove 531, resulting in jamming. In severe cases, the positioning rod 54 may even break. Therefore, in order to solve the above problems, in another embodiment of the present invention, a limiting top plate 42 is also included. The limiting top plate 42 is fixedly connected to one side of the clamping guide plate 41 near the mold top cover 5. Limiting plates 575 are fixedly connected to both sides of the mold top cover 5. When the bottom end of the mold top cover 5 is in contact with the top end of the mold base 51, the top end of the limiting plate 575 is below the bottom end of the limiting top plate 42.

[0037] It should be added that, such as Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, both the limiting top plate 42 and the limiting plate 575 are rectangular, and when the slide table 3 is in a position away from the hot press plate 21, the limiting plate 575 will not collide with the limiting top plate 42 when the mold top cover 5 moves upward.

[0038] In actual use, after the mold top cover 5 and the mold base 51 are closed, when the horizontal drive mechanism drives the slide 3 to move towards the hot press plate 21, at the beginning of the movement, the limiting plate 575 will be below the limiting top plate 42. That is, once the slide 3 moves towards the hot press plate 21, the mold top cover 5 cannot be lifted by the elastic element 56. During the sliding, the limiting top plate 42 will form an abutting fit with the limiting plate 575, thereby ensuring the closing stability between the mold top cover 5 and the mold base 51, until the mold top cover 5 is in the hot press plate 21. Below the pressure plate 21, the hot pressing operation can be carried out as the hot pressure plate 21 is pressed down. This design ensures that the mold top cover 5 will not be pushed up by the elastic element 56 during the movement of the mold top cover 5, or even after the mold top cover 5 has moved below the hot pressure plate 21. This avoids the situation where the positioning rod 54 is ejected from the positioning groove 53 and misaligned, and the hot pressure plate 21 presses down because the positioning rod 54 cannot enter the connecting groove 531, causing jamming. This also avoids the situation where the positioning rod 54 jams or breaks when it enters the positioning groove 53.

[0039] Another embodiment of the present invention discloses a molding process for a wearable electrotherapy belt, comprising the following steps: S1: The belt components are manually stacked inside the placement slot of the mold base 51; S2: Then the mold top cover 5 is slid into the positioning groove 53 through the positioning rod 54 to achieve the docking of the mold top cover 5 and the mold base 51; S3: Then press down the mold top cover 5 and start the second drive mechanism 4. By reducing the inner diameter of the circular groove formed by the end of the clamping rod 55 and the connecting groove 531, the positioning rod 54 is fixed. S4: Subsequently, as the horizontal drive mechanism moves downward toward the hot press plate 21, the limiting top plate 42 will engage with the limiting plate 575 on the mold top cover 5 to prevent the mold top cover 5 from opening. S5: Subsequently, the hot press plate 21 hot presses the waist belt component inside the mold top cover 5 and mold base 51. Then, the horizontal drive mechanism drives the slide table 3 away from the hot press plate 21. Finally, the operator removes the second drive mechanism 4, flips and opens the mold top cover 5, takes out the formed waist belt, and puts in a new waist belt component. This cycle is repeated to achieve efficient processing.

[0040] It should be further explained that the mold base 51 is fixed to the top of the slide table 3, and positioning grooves 53 are opened at the four corners of its top. Elastic elements 56 are provided inside. The bottom of the mold top cover 5 is provided with a positioning rod 54, which can be inserted into the positioning groove 53 to achieve precise docking. The second drive mechanism 4 is installed on both sides of the processing table 1. The output end is connected to the clamping guide plate 41, which can push the clamping rod 55 to clamp and fix the positioning rod 54, preventing the mold top cover 5 from being pushed up by the elastic element 56 during the movement. The flipping bracket 571 cooperates with the connecting plate 572 to realize the flipping opening and closing of the mold top cover 5. The limiting plate 42 cooperates with the limiting plate 575 to ensure that the mold top cover 5 remains closed during the movement, avoiding the positioning rod 54 from being misaligned, causing jamming or breakage. During processing, the operator first places the belt component in the placement slot of the mold base 51, then connects the mold top cover 5 with the positioning slot 53 via the positioning rod 54, presses them together, and then drives the clamping guide plate 41 to fix the positioning rod 54 via the second drive mechanism 4. Subsequently, the horizontal drive mechanism drives the slide table 3 to move below the hot press plate 21, and the first drive mechanism 2 drives the hot press plate 21 to press down to complete the hot pressing operation. After the hot pressing is completed, the slide table 3 is reset, the second drive mechanism 4 releases the clamping rod 55, and the elastic element 56 pushes the positioning rod 54 to separate the mold top cover 5 from the base. The operator can flip the mold top cover 5 through the flip card 571 to remove the finished product. The whole process achieves precise positioning, stable clamping and efficient operation.
