Description

Technical Field

[0001] This utility model relates to the field of vulcanization equipment technology, and in particular to a lifting mold structure for a fully automatic vacuum rubber vulcanizing machine. Background Technology

[0002] After vulcanization, rubber can significantly increase its strength and hardness, making the product more wear-resistant and durable. Vulcanization is a very common process, especially for footwear and tires.

[0003] For example, Chinese utility model patent document, announcement number CN210256882U, discloses an automatic mold lifting device for a fully automatic rubber vulcanizing machine. By adopting a mold structure that combines an upper mold, a color-separating mold, and a lower mold, it ensures that the equipment can perform two-color rubber vulcanization molding in a fully automatic manner, reducing costs and greatly improving work efficiency. Furthermore, it provides a corresponding mold lifting device, which specifically uses a corresponding structure to flip the mold and lift the color-separating mold.

[0004] The vulcanization temperature of rubber is relatively high, generally between 130 and 160 degrees Celsius, which makes the working environment for workers very hot. Using automatic devices can help reduce the labor intensity of workers. However, the existing mold lifting structures are mostly simple mold transfer or mold opening. In the production process of rubber products, after opening the mold, it is necessary to clean the mold. In some cases, residual rubber may be attached to the mold. If it is not removed, it will affect the quality of subsequent products. Utility Model Content

[0005] To overcome the technical defects of the existing technology, this utility model provides a mold lifting structure for a fully automatic vacuum rubber vulcanizing machine, which can automatically clean the mold without manual operation while reducing the leakage of hot air.

[0006] The technical solution adopted in this utility model is as follows: In existing mold lifting structures, most are lifted vertically by flipping or by telescopic components. In order to reduce space occupation, this structure adopts a flipping mold lifting method, including lifting arms that are movably engaged on both sides of the mold. The lifting arms are arranged in pairs, and each lifting arm is provided with a rotating part. A main shaft is fixed between the rotating parts. The main shaft is used to directly transmit force, so that the lifting arms on both sides of the mold rotate synchronously. A seat structure is provided on the main shaft. The seat structure is directly fixed to the lower half of the mold and serves as a flipping reference. A tail plate is fixed on the side of the rotating part away from the lifting arm. The tail plate is used to lengthen the lever arm and also to expand the range of the force-bearing components. An auxiliary plate parallel to the tail plate is fixed on the main shaft. A first force-bearing rod and a second force-bearing rod are fixed between the tail plate and the auxiliary plate. A heat insulation seat is installed through the first force-bearing rod and the second force-bearing rod. Because the rubber is in a high-temperature state for a long time during the vulcanization process, the heat insulation seat is used to isolate the temperature transfer between the components.

[0007] Preferably, in order to facilitate limiting the position of the lifting arm, the base structure includes a sleeve sleeved on the main shaft, an assembly part fixed at the bottom of the sleeve, an assembly plate fixed on the assembly part, and an assembly hole provided on the assembly plate.

[0008] Preferably, in order to expand the stress range of the component and isolate the temperature transmission, the heat insulation seat is provided with a first mounting hole that can be fitted onto the first force-bearing rod and a second mounting hole that can be fitted onto the second force-bearing rod. Both the first mounting hole and the second mounting hole are provided with a heat insulation layer. The upper surface of the heat insulation seat is fixed with a force-bearing part that is connected to the external force-applying component.

[0009] Preferably, in order to facilitate fixed connection with the mold, a snap-fit ​​groove is provided on the side wall of the lifting arm. Since the rotation center of the mold and the rotation center of the lifting arm are not the same, the length of the snap-fit ​​groove needs to be adapted according to the actual needs. A protruding slider should be provided on the mold accordingly, and a reinforcing rib is fixed between the main shaft and the rotating part.

[0010] Preferably, in order to facilitate the movement of the cleaning mechanism to a suitable position, a pair of driving components are also provided above the lifting arm. The driving components include a bearing shell, and a connecting part is fixed on the bearing shell. The connecting part is used to fix with an external telescopic component. The external telescopic component can perform basic reciprocating motion, that is, move on the mold surface, and can even drive the cleaning mechanism to approach or move away from the mold.

[0011] Preferably, in order to adapt to different mold shapes, a cleaning mechanism is provided inside the support shell on one side. The cleaning mechanism includes a tube body, which is movably engaged with the inner wall of the support shell. One end of the tube body is provided with a Y-shaped nozzle.

[0012] Preferably, in order to enable the tube body to have a certain fault tolerance and adaptability, the outer wall of the tube body is provided with a protrusion, and a return spring is connected between the protrusion and the bearing shell. The outer wall of the end of the tube body extending outside the bearing shell is also provided with the protrusion, and an exhaust fan is provided on the side wall of the bearing shell.

[0013] Preferably, in order to facilitate cleaning with a cleaning mechanism, a sealed chamber is provided inside the bearing shell on the other side via a partition, an exhaust fan is fixed on the side wall of the sealed chamber, and an outlet is provided on the bearing shell.

[0014] The beneficial effects of this utility model are: it can better accept external force through the tail plate, disperse the force range of the components, and the heat insulation seat can avoid the transfer of temperature and reduce the impact of temperature on the components while increasing the force-bearing area. The cleaning mechanism can clean the residual deposits on the mold and absorb the airflow through the bearing shell on the opposite side to discharge impurities and hot air together. If the Y-shaped nozzle is pushed by the mold, the Y-shaped nozzle can compress the return spring to avoid damaging the mold. When the bearing shells are connected, the exhaust fan can introduce external airflow, while the exhaust fan on the opposite side can smoothly discharge the airflow, thereby realizing fully automatic mold cleaning.

[0022] The present invention will be further described below with reference to the accompanying drawings:

[0023] like Figures 1-6 As shown, this embodiment provides a lifting mold structure for a fully automatic vacuum rubber vulcanizing machine, including lifting arms 1 that are movably latched onto both sides of the mold. The lifting arms 1 are arranged in pairs, and each lifting arm 1 has a rotating part. A main shaft 2 is fixed between the rotating parts. The main shaft 2 is used to directly transmit force, causing the lifting arms 1 located on both sides of the mold to rotate synchronously. A seat structure 3 is provided on the main shaft 2. The seat structure 3 is directly fixed to the lower half of the mold and serves as a flipping reference. A tail plate 4 is fixed on the side of the rotating part away from the lifting arm 1. The tail plate 4 is used to extend the lever arm and also expand the range of the force-bearing part 604. An auxiliary plate 5 parallel to the tail plate 4 is fixed on the main shaft 2. A first force-bearing rod and a second force-bearing rod are fixed between the tail plate 4 and the auxiliary plate 5. Through the first force-bearing rod and The second force-bearing rod is equipped with a heat insulation seat 6. Because the rubber is in a high-temperature state for a long time during the vulcanization process, the heat insulation seat 6 is used to isolate the temperature transfer between the components. A snap-fit ​​groove 101 is opened on the side wall of the lifting arm 1. Because the rotation center of the mold and the rotation center of the lifting arm 1 are not the same, the length of the snap-fit ​​groove 101 needs to be adapted according to the actual needs. A protruding slider should be provided on the mold. A reinforcing rib is fixed between the main shaft 2 and the rotating part, which can facilitate the fixed connection with the mold. When the mold needs to be lifted, the external force-applying component presses down on the heat insulation component, and then the main shaft 2 is rotated through the tail plate 4. Then the upper part of the mold is flipped up through the lifting arm 1. The better force range can prevent the components from being damaged and improve the service life of the components.

[0024] The base structure 3 includes a sleeve 301 sleeved on the main shaft 2. An assembly part 302 is fixed at the bottom of the sleeve 301. An assembly plate 303 is fixed on the assembly part 302. An assembly hole is provided on the assembly plate 303, which can facilitate the restriction of the position of the lifting arm 1. During assembly, the equipment plate needs to be fixed to the lower plate of the mold by fixing bolts.

[0025] The heat insulation base 6 has a first mounting hole 601 that can be fitted onto the first force-bearing rod and a second mounting hole 602 that can be fitted onto the second force-bearing rod. Both the first mounting hole 601 and the second mounting hole 602 are provided with heat insulation layers 603. The upper surface of the heat insulation base 6 is fixed with a force-bearing part 604 that is connected to an external force-applying component. This can expand the force-bearing range of the component and isolate the transmission of temperature.

[0026] It also includes a pair of drive assemblies 7 located above the lifting arm 1. The drive assembly 7 includes a bearing shell 701, on which a connecting part 702 is fixed. The connecting part 702 is used to fix with an external telescopic component. The external telescopic component can perform basic reciprocating motion, that is, move on the mold surface, and can even drive the cleaning mechanism 8 to move closer to or away from the mold. This makes it easier to drive the cleaning mechanism 8 to move to a suitable position. A cleaning mechanism 8 is provided inside one side of the bearing shell 701. The cleaning mechanism 8 includes a tube body 801, which is movably engaged with the inner wall of the bearing shell 701. One end of the tube body 801 is provided with a Y-shaped nozzle 802, which can adapt to different mold shapes. The outer wall of the tube body 801 is provided with a protrusion, and a return spring 803 is connected between the protrusion and the bearing shell 701. The outer wall of the end of the tube body 801 extending outside the bearing shell 701 is also provided with a protrusion. An exhaust fan 9 is provided on the side wall of the bearing shell 701, which allows the tube body 801 to have a certain degree of fault tolerance. The other side of the support shell 701 has a sealed chamber provided by a partition. The side wall of the sealed chamber is fixed with an exhaust fan 10. The support shell 701 has an exhaust port. This can be used in conjunction with the cleaning mechanism 8 for cleaning. After the mold is lifted, the support shell 701 can be moved to the forming groove of the mold. In use, it is preferable to connect the two support shells 701 together. This is more conducive to the discharge of impurities and can reduce the escape of hot air. High-pressure clean gas is preferably introduced into the pipe body 801. In use, if the Y-type nozzle 802 is pushed by the mold, the Y-type nozzle 802 can compress the return spring 803 to avoid damaging the mold. When the support shells 701 are connected, the exhaust fan 9 can introduce external airflow, and the exhaust fan 10 on the opposite side can smoothly discharge the airflow, thereby realizing fully automatic mold cleaning. Similarly, when it is necessary to clean the lower part of the mold, a drive component 7 and a cleaning structure can be added, or a self-rotating external telescopic component can be used.

[0027] This structure can better accept external forces through the tail plate 4, disperse the force range of the components, and the heat insulation seat 6 can avoid the transfer of temperature and reduce the impact of temperature on the components while increasing the force-bearing area. The cleaning mechanism 8 can clean the residual deposits on the mold and absorb the airflow through the bearing shell 701 on the opposite side to discharge impurities and hot air together.

Those skilled in the art should understand that this invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this invention. Various changes and modifications may be made to this invention without departing from its spirit and scope.
