Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] Please see Figure 2 This invention provides a solid rubber compound injection molding mechanism 20. The solid rubber compound injection molding mechanism 20 utilizes solid flat vulcanization production technology. The solid rubber compound injection molding mechanism 20 includes a driving component 21, an upper hot press plate 22, a mold 23, an injection plate 24, a pressure plate 25, and a fixing plate 26. The driving component 21, the upper hot press plate 22, the mold 23, the injection plate 24, and the pressure plate 25 are arranged sequentially from bottom to top according to the direction shown in the figure.

[0029] The driving component 21 is driven to connect with the upper hot press plate 22, and the mold 23 is mounted on the upper hot press plate 22. The solid adhesive material 30 is placed on the mold 23, and the driving component 21 drives the upper hot press plate 22, the mold 23, and the solid adhesive material 30 to move toward the rotating injection plate 24.

[0030] It is understood that the solid rubber compound 30 is a solid relative to the liquid rubber compound. The solid rubber compound 30 is actually a gel-like substance, which is a rubber compound with viscous and semi-solid properties, such as rubber compound or silicone rubber compound.

[0031] It can also be understood that the mold 23 can be detachably mounted on the upper hot press plate 22. With detachable mounting, when different shapes of products need to be formed, the corresponding mold can be replaced. Those skilled in the art can choose existing detachable mounting structures according to actual needs; there are no specific limitations here. For example, detachable mounting could mean directly placing the mold 23 on the upper hot press plate 22, or it could mean that the mold 23 and the upper hot press plate 22 are relatively fixed in the horizontal direction through a concave-convex structure.

[0032] Please refer to the following: Figure 2 and Figure 3 ,in, Figure 3 Figure 1 shows a partially exploded view of the injection molding mechanism for solid adhesive material. The mold 23 includes a stacked template 231 and an injection plate 233. The injection plate 233 is stacked on the template 231 away from the upper hot press plate 22. The solid adhesive material 30 is placed on the injection plate 233. When the solid adhesive material 30 is under pressure, it enters the cavity 2311 of the template 231 through the injection hole 2331 of the injection plate 233, thus forming the mold. The surface of the injection plate 233 on which the solid adhesive material 30 is placed has an anti-stick coating to prevent the solid adhesive material 30 from sticking.

[0033] Please refer to the following: Figure 3 and Figure 4 , Figure 4 Figure 1 shows a cross-sectional view of the solid rubber material injection molding mechanism. The injection plate 24 is located on the side of the mold 23 away from the upper hot press plate 22, and is initially spaced at a preset distance from the mold 23. The injection plate 24 includes a first body 241, which includes a connected side wall 2411 and an undercut structure 2413. The side wall 2411 forms a hollow material groove 242, and the undercut structure 2413 extends from the side wall 2411 toward the mold 23 toward the hollow material groove 242. When the driving member 21 drives the upper hot press plate 22, the mold 23, and the solid rubber material 30 to move toward the injection plate 24, the solid rubber material 30 can be pushed into the hollow material groove 242.

[0034] It is understood that the driving component 21 is a power-providing device, which can be an existing power device, such as a cylinder, hydraulic cylinder, motor, etc., and is not specifically limited here. It is also understood that if the motor is a type of motor that converts electrical energy into rotational mechanical energy, it needs to be converted into linear mechanical energy through mechanical conversion mechanisms such as lead screws, racks, belts, and crank-slider mechanisms. In this embodiment, the driving component 21 is specifically a hydraulic cylinder.

[0035] The pressure plate 25 and the rotary injection plate 24 are movably connected and inserted into the hollow material groove 242 at the end away from the mold 23. The pressure plate 25 includes a second body 251 and a push-out protrusion 253 connected together. The second body 251 and the first body 241 are movably connected and inserted into the hollow material groove 242.

[0036] The pressure plate 25 and the rotating plate 24 can be connected by a spring 271 and a guide post 272 to achieve a relatively movable connection. Specifically, the side wall 2411 and the surface opposite to the pressure plate 25 are provided with a pair of coaxial grooves. One end of the spring 271 abuts against the bottom of the first groove 24111 of the side wall 2411, and the other end abuts against the bottom of the second groove 2511 of the second body 251. The first end of the guide post 272 passes through the through hole 24113 of the side wall 2411 and is fixed to the second body 251. The second end of the guide post 272 is provided with a limiting part 2721. The diameter of the limiting part 2721 is larger than that of the through hole 24113. With the extension and retraction of the spring 271, the limiting part 2721 intermittently abuts against the side wall 2411.

[0037] It can be understood that the number of springs 271 and groove pairs can be multiple, corresponding one-to-one. Preferably, the sidewall 2411 is square-shaped, the first grooves 24111 are distributed around the hollow material groove 242, and the number of guide posts 272 is four, which are set at the four corners of the sidewall 2411.

[0038] It is also understood that after the driving component 21 drives the mold 23 to close with the rotating injection plate 24, it continues to drive the mold 23 to move the rotating injection plate 24, which will compress the spring 271, making the gap between the second body 251 and the first body 241 smaller. The guide post 272 moves relative to the mold 23. Therefore, it is necessary to reserve displacement space for the relative displacement of the guide post 272. The guide post 272 is located outside the projection range of the mold 23 on the rotating injection plate 24.

[0039] The pressure plate 25 is fixed to the fixing plate 26. It is understood that when the fixing plate 26 fixes the pressure plate 25, the pressure plate 25 and the upper hot press plate 22 should initially maintain a preset distance in the vertical direction shown in Figure 1 so as to install the mold 23 and place the solid adhesive 30. The fixing plate 26 can be fixed above the upper hot press plate 22 shown in Figure 1 by a support structure. For example, a support frame or support plate extending from bottom to top in the direction shown in Figure 1 can be set, and the fixing plate 26 can be fixed to the support frame or support plate. Or, a shell covering the fixing plate 26 can be set, and the fixing plate 26 can be fixed to the downward-facing surface of the shell, etc. The specific method is not limited here.

[0040] In a further embodiment, to improve the stability of the driving member 21 driving the upper hot press plate 22, a fixing post 28 can be provided. Specifically, the fixing post 28 extends along the upper hot press plate 22 toward the rotating plate 24 and penetrates the upper hot press plate 22. The driving member 21 drives the upper hot press plate 22 to move along the fixing post 28, and the fixing post 28 guides the direction of movement of the upper hot press plate 22, such as... Figure 5 As shown. Simultaneously, the fixing plate 26 is fixed to the fixing post 28.

[0041] Please see Figures 6A-6C Figure 1 shows a schematic diagram of the working process of the solid rubber material transfer molding mechanism. When the solid rubber material transfer molding mechanism 20 is working, the solid rubber material 30 is placed on the injection plate 233. The controller controls the drive component 21 to drive the upper hot press plate 22 towards the transfer plate 24, causing the mold 23 and the solid rubber material 30 to move synchronously. When the mold 23 reaches the transfer plate 24, it pushes the solid rubber material 30 into the hollow material trough 242, completing the feeding process. Figure 6A As shown; the driving component 21 continues to drive the upper hot press plate 22, the mold 23 drives the injection plate 24 to move towards the pressure plate 25, the push protrusion 253 moves relative to the solid material 30 in the hollow material groove 242, applies pressure to the solid material 30, and presses the solid material 30 into the injection hole 2331 of the injection plate 233, into the cavity 2311 of the template 231, completing the pressing process, as shown. Figure 6B As shown; the driving component 21 continues to drive the upper hot press plate 22 to reset, the mold 23 separates from the injection plate 24, and the remaining solid adhesive material 30 remains in the hollow material groove 242, as shown. Figure 6C As shown.

[0042] It is understandable that the controller can be an MCU controller, CPU controller, PLC, microcontroller, etc. Specifically, it can be the DS-J160 flat vulcanizing machine controller or the DLK series flat vulcanizing machine microcomputer controller.

[0043] It should be noted that during the pressing process, the mold 23 and the rotating injection plate 24 are sealed and abutted together, and the push-up protrusion 253 and the side wall 2411 are sealed and abutted together, so as to prevent the solid adhesive 30 from overflowing from between the mold 23 and the rotating injection plate 24 and between the push-up protrusion 253 and the side wall 2411 when under force.

[0044] It is understood that a sealing contact can be achieved by providing a sealing ring between the mold 23 and the injection plate 24, and between the push-out protrusion 253 and the side wall 2411. For example, a sealing ring is provided on the surface of the injection plate 24 facing the mold 23, and a sealing ring is provided on the outer sleeve of the push-out protrusion 253.

[0045] It should also be noted that during the pressing process, the pusher protrusion 253 applies pressure to the solid material 30, causing the solid material 30 to deform. After pressing is completed, the drive component 21 resets. When the rotating injection plate 24 separates from the mold 23, the remaining solid material 30 after pressing is caught by the inverted structure 2413 of the rotating injection plate 24 and returns to its original shape with the spring 271. The rotating injection plate 24 resets, generating suction on the remaining solid material 30. At the same time, due to the viscous nature of the solid material 30, the remaining solid material 30 will follow the pusher protrusion 253 and remain in the hollow material groove 242. At this time, the mold 23 can be replaced to press the material again.

[0046] It is understandable that, based on the amount of the solid adhesive 30, multiple molds 23 can be pressed together with a single feeding.

[0047] It should be noted that the solid adhesive material transfer molding mechanism 20 also includes a vacuum pump 29, which is connected to the hollow material tank 242 and evacuates the hollow material tank 242 during the pressing process.

[0048] Specifically, an air passage can be provided on the pressure plate 25, or a connecting air passage can be provided on the fixed plate 26 and the pressure plate 25, and the vacuum pump 29 can be connected to the hollow material tank 242 through the air passage.

[0049] It should also be noted that the structure of the upper hot press plate 22 can adopt the existing hot press plate structure of a flat vulcanizing machine. Specifically, it can be equipped with a heating device, a pressure sensor and a temperature sensor. The heating device can be an electric heating rod, which is embedded in the upper hot press plate 22 to provide a temperature environment for the vulcanization process of the solid rubber compound.

[0050] It is understood that those skilled in the art can determine whether the pressing is complete by detecting pressure and temperature, thereby controlling the drive component 21 to stop driving. The pressure sensor and temperature sensor are set on the upper hot platen 22. When the pressure value and temperature value reach the preset threshold, it indicates that the solid adhesive 30 has filled the cavity 2311, the pressing is complete, the drive component 21 is controlled to stop driving and increase, and the heating device stops heating.

[0051] It should be noted that you should refer to [the website / platform] again. Figure 4 The injection plate 233 is made of heat-insulating material, and the injection plate 24 further includes a water inlet, a water channel 243, and a water outlet. The water channel 243 is located on the side wall 2411. The heat insulation performance of the injection plate 233 reduces the heat transferred from the upper hot platen 22 to the injection plate 24. Simultaneously, the water channel 243 provides cooling, ensuring that the solid adhesive 30 in the hollow material tank 242 does not prematurely solidify, thus preventing it from being pressed into the mold 23.

[0052] Specifically, the inlet can be connected to an inlet pipe, and the outlet can be connected to an outlet pipe. Cold water is introduced into the water channel 243 through the inlet pipe to cool the rotating plate 24.

[0053] Compared with the prior art, the solid rubber material transfer molding mechanism 20 provided in this embodiment of the utility model is equipped with a transfer plate 24. When pressing material, the solid rubber material 30 is contained in the hollow material groove 242 for pressing, which eliminates the need for precise cutting and weighing based on the capacity of each mold cavity, thus reducing the difficulty of operation.

[0054] The hollow material groove 242 of the injection plate 24 covers all the injection holes 2331 of the injection plate 233 for pressing material, eliminating the need to place material according to the mold cavity position and saving manpower.

[0055] After the solid adhesive material 30 is fed and pressed, the remaining solid adhesive material 30 remains in the hollow material trough 242, and the mold 23 can be directly replaced for continuous pressing, thereby improving production efficiency.

[0056] Please see Figure 7This is a schematic diagram of a solid flat vulcanizing machine provided by this utility model. The solid flat vulcanizing machine 100 includes a transfer molding mechanism 20 for the above-mentioned solid rubber material and a controller 40. The controller 40 is electrically connected to the upper hot press plate 22, and specifically electrically connected to the drive component 21, the vacuum pump 29, the heating device, the temperature sensor, and the pressure sensor.

[0057] The above description is only a part of the embodiments of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the contents of the utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
