Please refer to fig. 1a, fig. 1b and fig. 1c in combination. Fig. 1a, 1b and 1c show the external shape of a rubber article 100 from the top, front and left view, respectively. The following embodiments provide an outer mold of a vulcanizing device, an inner mold of a vulcanizing device, and a multi-station vulcanizing device for processing a rubber product 100 to vulcanize the rubber product 100. It should be noted that the rubber article 100 is only an example, and it is understood that the following embodiments provide an outer mold of a vulcanizing device, an inner mold of a vulcanizing device, and a multi-station vulcanizing device that can be used to process rubber articles of other shapes. When rubber products with other shapes are required to be processed, the shapes of the molding surfaces of the outer mold of the vulcanizing device and the inner mold of the vulcanizing device are only required to be correspondingly changed according to the outer shape of the rubber products.

The rubber article 100 may be used to make a guard band (which may be used in hull protection and the like scenarios). In order to improve the structural strength of the rubber product 100, a metal skeleton is provided in the rubber product 100.

Example 1:

please refer to fig. 2a and fig. 2b in combination. Fig. 2a is a schematic perspective view of an outer mold 200 of the vulcanizing device according to this embodiment. Fig. 2b is a schematic top view of the outer mold 200 of the vulcanizing device according to this embodiment. The curing device overmold 200 includes two first overmolds 210, one second overmold 220, first overmold drive means, and second overmold drive means. The curing device outer mold 200 is adapted to cooperate with the curing device inner mold to cure the rubber article 100.

The two first outer molds 210 are arranged at an opposite interval in the AB direction. The surfaces of the two first outer molds 210 that are adjacent to each other are first outer mold forming surfaces 210a. The first outer molding surface 210a is shaped to conform to the outer side 110a of the rubber article 100 (shown in fig. 1a, 1b, and 1 c) for pressing the outer side 110a of the rubber article 100 during vulcanization molding so that the outer side 110a of the rubber article 100 is formed into a predetermined shape. The first outer mold 210 is further provided with a first outer mold steam port 281 for introducing high temperature steam into the first outer mold 210 to cure the sidewall 110 of the rubber product 100 at a high temperature.

The second outer die 220 is arranged at a position near one end of the first outer die 210 in the CD direction. The surface of the second outer mold 220 facing the space between the two first outer molds 210 is a second outer mold forming surface 220a. The second outer molding surface 220a has a shape corresponding to the outer end surface 120a of the rubber product 100 (shown in fig. 1a, 1b and 1 c) for pressing the outer end surface 120a of the rubber product 100 during vulcanization molding so that the outer end surface 120a of the rubber product 100 is formed into a predetermined shape. The second outer mold 220 is further provided with a second outer mold steam port 282 for introducing high temperature steam into the second outer mold 220 to cure the end wall 120 of the rubber product 100 at a high temperature.

Further, the first outer die 210 is provided with a first outer die contact surface 210b near one end of the second outer die 220 in the CD direction. Two second outer mold contact surfaces 220b are provided on the second outer mold 220. The two second outer mold contact surfaces 220b are located on both sides of the second outer mold forming surface 220a in the AB direction and are symmetrically disposed with respect to the second outer mold forming surface 220 a. The two second outer mold contact surfaces 220b can be fitted in one-to-one correspondence with the two first outer mold contact surfaces 210b.

The first outer mold driving device is in transmission connection with the first outer mold 210, and is used for driving the two first outer molds 210 to approach or separate from each other along the direction AB. The two first outer molds 210 are brought closer to each other in the AB direction so that the first outer mold surface 210a is press-fitted on the outer side 110a of the rubber article 100. The two first outer molds 210 are moved away from each other in the direction AB so that the first outer mold surface 210a is disengaged from the outer side 110a of the rubber article 100. It will be appreciated that the first over-mold drive may be implemented in a variety of configurations, such as a hydraulic drive, a pneumatic drive, or a lead screw nut drive, among others. In this embodiment, the first overmolded drive is a hydraulic drive. The two first outer mold driving devices are respectively connected with the two first outer molds 210 in a transmission way. The first external mold driving device comprises four hydraulic cylinders, namely a hydraulic cylinder 231, a hydraulic cylinder 232, a hydraulic cylinder 233 and a hydraulic cylinder 234. Hydraulic cylinders 231, 232, 233 and 234 are provided on the side of the first outer mold 210 facing away from the first outer mold forming surface 210 a. The hydraulic cylinder 231, the hydraulic cylinder 232, the hydraulic cylinder 233, and the hydraulic cylinder 234 are arranged side by side in the CD direction. Piston rods of the hydraulic cylinders 231, 232, 233 and 234 are connected with the first outer mold 210. The cylinders of the hydraulic cylinders 231, 232, 233 and 234 are fixedly arranged. When the piston rods of the hydraulic cylinders 231, 232, 233, and 234 are extended, the two first outer molds 210 are close to each other in the AB direction, and when the piston rods of the hydraulic cylinders 231, 232, 233, and 234 are retracted, the two first outer molds 210 are far away from each other in the AB direction.

The second outer mold driving device is in driving connection with the second outer mold 220, and is used for driving the second outer mold 220 to approach or separate from the first outer mold 210 along the CD direction. The second outer die 220 is adjacent to the first outer die 210 such that the second outer die forming surface 220a is press-fitted on the outer end surface 120a of the rubber article 100. The second outer mold 220 is away from the first outer mold 210 such that the second outer mold forming surface 220a is disengaged from the outer end surface 120a of the rubber article 100. It will be appreciated that the second outer die driving means may be realized by various structures, such as a hydraulic driving means, a pneumatic driving means, or a screw nut driving means, etc. In this embodiment, the second external mold driving device is a hydraulic driving device. The second outer die driving means includes a hydraulic cylinder 241. The hydraulic cylinder 241 is provided on the side of the second outer die 220 facing away from the second outer die forming surface 220 a. A piston rod of the hydraulic cylinder 241 is connected to the second outer die 220. The cylinder body of the hydraulic cylinder 241 is fixedly provided. The second outer die 220 approaches the first outer die 210 in the CD direction when the piston rod of the hydraulic cylinder 241 is extended, and the second outer die 220 moves away from the first outer die 210 in the CD direction when the piston rod of the hydraulic cylinder 241 is retracted.

The two first outer dies 210 are adjacent to each other in the AB direction, and the second outer die 220 is adjacent to the first outer die 210 in the C direction until the first outer die contact surface 210b and the second outer die contact surface 220b come into contact with each other. The first outer molding surface 210a and the second outer molding surface 220a form a smooth and continuous outer molding surface at this time. In this condition, the curing device outer mold 200 is in operation. The outer molding surface presses the outer surface of the rubber product 100, forms the outer surface of the rubber product 100 into a predetermined shape, and vulcanizes the rubber product 100 at a high temperature. After the rubber article 100 is vulcanized, the two first outer molds 210 are separated from each other in the AB direction, the second outer mold 220 is separated from the first outer mold 210 in the D direction, and the first outer mold contact surface 210b is separated from the second outer mold contact surface 220b. In this state, the vulcanizing device outer mold 200 is in an open state (fig. 1 and 2 each show a structure in which the vulcanizing device outer mold 200 is in an open state). At this time, the first outer molding surface 210a is separated from the outer side surface 110a of the rubber product 100, and the second outer molding surface 220a is separated from the outer side surface 120a of the rubber product 100. The first outer mold driving device and the second outer mold driving device drive the outer mold 200 of the vulcanizing device to be switched from the working state to the open state, so that the demolding of the rubber product 100 relative to the outer mold 200 of the vulcanizing device is automatically realized. Meanwhile, when the vulcanizing device outer mold 200 is in an open state, demolding of the rubber product 100 with respect to the vulcanizing device inner mold is facilitated, and mounting of the rubber product 100 to be processed onto the vulcanizing device inner mold is facilitated.

In the present embodiment, the distance between the two first outer die contact surfaces 210b is gradually increased along the direction (D direction) in which the second outer die 220 is away from the first outer die 210, and the distance between the two second outer die contact surfaces 220b is also gradually increased. In this way, the cooperation between the first outer mold contact surface 210b and the second outer mold contact surface 220b can simultaneously act as a guide when the curing device outer mold 200 is shifted from the open state to the working state, facilitating accurate movement of the first outer mold 210 and the second outer mold 220 to predetermined positions such that the first outer mold forming surface 210a and the second outer mold forming surface 220a form a smooth and continuous outer forming surface.

In the present embodiment, the first outer mold 210 includes four sub-outer molds, which are a sub-outer mold 211, a sub-outer mold 212, a sub-outer mold 213, and a sub-outer mold 214, which are sequentially arranged in the CD direction. The hydraulic cylinder 231, the hydraulic cylinder 232, the hydraulic cylinder 233, and the hydraulic cylinder 234 are connected to the sub-outer die 211, the sub-outer die 212, the sub-outer die 213, and the sub-outer die 214, respectively, and control the four sub-outer dies to move in the AB direction, respectively. When the vulcanizing device outer mold 200 is switched from the operating state to the open state, the sub outer mold 211 and the sub outer mold 213 are first moved outwardly by the hydraulic cylinders 231 and 233, respectively, and then the hydraulic cylinders 232 and 234 are moved outwardly by the sub outer mold 212 and the sub outer mold 214, respectively. When the hydraulic cylinders 231 and 233 respectively carry the sub-outer mold 211 and the sub-outer mold 213 to move outward, the sub-outer mold 212 and the sub-outer mold 214 are still press-fitted on the rubber product 100, so that the rubber product 100 is more easily separated from the sub-outer mold 211 and the sub-outer mold 213. The sub-outer mold 211 and the sub-outer mold 213 can be separated from the rubber product 100 more easily after the sub-outer mold 212 and the sub-outer mold 214 are separated from the rubber product 100. In this way, the rubber product 100 can be prevented from being deformed by pulling the rubber product 100 by the first outer die 210 during the demolding process. It should be noted that the number of sub-molds and the order of movement at the time of demolding can be configured as desired, and this embodiment is merely an example.

Further, in the present embodiment, adjacent sub-outer dies in the first outer die 210 are contacted by the outer die limit surface 21a inclined with respect to the AB direction. The outer mold limit surfaces 21a are inclined relative to the direction AB and can act as guides during movement of the sub-outer molds to facilitate accurate movement of the sub-outer molds to predetermined positions, with the inner sides of each sub-outer mold forming a smooth and continuous first outer mold surface 210a.

In this embodiment, the first outer mold 210 and the second outer mold 220 are each provided with a first outer mold locking structure 250 for detachably connecting with the inner mold of the vulcanizing device in an operating state. The first outer mold locking structure 250 is connected to the inner mold of the curing apparatus when the outer mold 200 of the curing apparatus is in an operative state, thereby maintaining the size of the cavity formed by the outer mold 200 of the curing apparatus and the inner mold of the curing apparatus and continuously applying pressure to the rubber product 100. Further, in the present embodiment, four first outer mold locking structures 250 are provided at the upper end of the first outer mold 210, corresponding to the sub-outer mold 211, the sub-outer mold 212, the sub-outer mold 213 and the sub-outer mold 214, respectively, and one first outer mold locking structure 250 is provided at the upper end of the second outer mold 220. The first outer mold locking structure 250 includes a first pallet 251 extending toward the inside of the curing device outer mold 200, and a first outer mold locking cylinder 252 provided on the first pallet 251. The first plate 251 is provided with a through hole (not shown). When locking is needed, the piston rod of the first outer mold locking cylinder 252 extends out, penetrates through the first supporting plate 251 and is provided with a through hole, and extends into a hole formed in the upper end of the inner mold of the vulcanizing device. Thus, the locking between the outer mold 200 of the vulcanizing device and the inner mold of the vulcanizing device is realized.

In this embodiment, the curing device outer mold 200 further includes a base body supporting the first outer mold 210 and the second outer mold 220. The base includes a first base 261 supporting the first outer die 210 and a second base (not shown) supporting the second outer die 220. The first base 261 is provided with a first outer die rail 262 extending in the AB direction, and the first outer die 210 is slidably engaged with the first outer die rail 262. The second base is provided with a second outer mold rail 263 extending in the CD direction, and the second outer mold 220 is slidably engaged with the second outer mold rail 263. The first and second outer die rails 262 and 263 guide the first and second outer dies 210 and 220, respectively, so that the first outer die 210 can move exactly in the AB direction and the second outer die 220 can move exactly in the CD direction. Four outer die fixing columns 264 are fixedly arranged on the first base 261, and cylinder bodies of the hydraulic cylinders 231, 232, 233 and 234 are fixedly connected with the four outer die fixing columns 264 respectively. An external mold fixing column 264 is fixedly arranged on the second substrate, and the cylinder body of the hydraulic cylinder 241 is fixedly connected with the external mold fixing column.

In this embodiment, the first and second outer molds 210 and 220 are each provided with a second outer mold locking structure 270 for detachably connecting with the base body in an open state, thereby maintaining the vulcanizing device outer mold 200 in an open state and preventing erroneous movement of the vulcanizing device outer mold 200. Further, in the present embodiment, four second outer mold locking structures 270 are provided at the lower end of the first outer mold 210, corresponding to the sub-outer mold 211, the sub-outer mold 212, the sub-outer mold 213 and the sub-outer mold 214, respectively, and two second outer mold locking structures 270 are provided at the lower end of the second outer mold 220. The second outer mold locking structure 270 includes a second supporting plate 271 extending to the outside of the vulcanizing device outer mold 200, and a second outer mold locking cylinder 272 provided on the second supporting plate 271. The second supporting plate 271 is provided with a through hole (not shown). When locking is required, the piston rod of the second outer mold locking cylinder 272 extends out, penetrates through the second supporting plate 271, and extends into the hole formed in the base body.

In summary, the outer mold 200 of the vulcanizing device provided in this embodiment can be automatically switched between a working state and an open state, so as to automatically realize demolding of the rubber product 100 with respect to the outer mold 200 of the vulcanizing device. Meanwhile, when the outer mold 200 of the vulcanizing device is in an open state, demolding of the rubber product 100 relative to the inner mold of the vulcanizing device is facilitated, and the rubber product 100 to be processed is conveniently mounted on the inner mold of the vulcanizing device.

Example 2:

please refer to fig. 3a, fig. 3b and fig. 3c in combination. Fig. 3a is a schematic perspective view of an inner mold 300 of a vulcanizing device according to the present embodiment. Fig. 3b is a schematic top view of the inner mold 300 of the vulcanizing device according to the present embodiment. Fig. 3c is a schematic left-view structure of the inner mold 300 of the vulcanizing device according to this embodiment. The curing apparatus inner mold 300 includes two first inner molds 310, one second inner mold 320, a first inner mold driving means, and a second inner mold driving means. The curing apparatus inner mold 300 is adapted to cooperate with an outer mold of a curing apparatus to cure the rubber article 100.

The two first inner molds 310 are arranged at an opposite interval in the AB direction. The surfaces of the two first inner molds 310 away from each other are first inner mold forming surfaces 310a. The first inner molding surface 310a has a shape corresponding to the inner side 110b of the rubber product 100 (shown in fig. 1a and 1 c) for pressing the inner side 110b of the rubber product 100 during vulcanization molding so that the inner side 110b of the rubber product 100 is formed into a predetermined shape. The first inner mold 310 is further provided with a first inner mold steam port 381 for introducing high temperature steam into the first inner mold 310, thereby vulcanizing the sidewall 110 of the rubber product 100 at a high temperature.

The second inner mold 320 is disposed between the two first inner molds 310. The second inner mold 320 includes a second inner mold forming surface 320a. The second inner molding surface 320a has a shape corresponding to the inner end surface 120b of the rubber product 100 (shown in fig. 1a and 1 c) for pressing the inner end surface 120b of the rubber product 100 during vulcanization molding so that the inner end surface 120b of the rubber product 100 is formed into a predetermined shape. A second mold steam port 382 is also provided on the second mold 320 for introducing high temperature steam into the second mold 320 to cure the end wall 120 of the rubber article 100 at an elevated temperature.

Further, one end of the first inner die 310 in the CD direction is provided with a first inner die contact surface 310b. Two second inner mold contact surfaces 320b are provided on the second inner mold 320. The two second inner mold contact surfaces 320b are located at both sides of the second inner mold forming surface 320a in the AB direction and are symmetrically disposed with respect to the second inner mold forming surface 320a. The two second inner mold contact surfaces 320b can be bonded to the two first inner mold contact surfaces 310b in a one-to-one correspondence.

The first internal mold driving device is in transmission connection with the first internal mold 310 and is used for driving the two first internal molds 310 to approach or separate from each other along the AB direction. The two first inner molds 310 are spaced apart from each other in the AB direction, so that the first inner mold forming surfaces 310a are press-fitted on the inner side surfaces 110b of the rubber product 100. The two first inner molds 310 are brought close to each other in the AB direction, so that the first inner mold forming surface 310a is separated from the inner side 110b of the rubber article 100. It will be appreciated that the first internal mold drive may be implemented in a variety of configurations, such as a hydraulic drive, a pneumatic drive, or a lead screw nut drive, among others. In this embodiment, the first internal mold driving device is a hydraulic driving device. The two first inner mold driving devices are respectively connected with the two first inner molds 310 in a transmission way. The first internal mold driving device comprises four hydraulic cylinders, namely a hydraulic cylinder 331, a hydraulic cylinder 332, a hydraulic cylinder 333 and a hydraulic cylinder 334. The hydraulic cylinder 331, the hydraulic cylinder 332, the hydraulic cylinder 333, and the hydraulic cylinder 334 are all disposed on the side of the first inner die 310 facing away from the first inner die forming surface 310 a. The hydraulic cylinder 331, the hydraulic cylinder 332, the hydraulic cylinder 333, and the hydraulic cylinder 334 are arranged side by side in the CD direction. The piston rods of the hydraulic cylinders 331 and 332 are connected to one of the first inner molds 310, and the piston rods of the hydraulic cylinders 333 and 334 are connected to the other of the first inner molds 310. The cylinders of the hydraulic cylinder 331, the hydraulic cylinder 332, the hydraulic cylinder 333, and the hydraulic cylinder 334 are fixedly provided. When the piston rods of the hydraulic cylinders 331, 332, 333, and 334 are extended, the two first inner molds 310 are away from each other in the AB direction, and when the piston rods of the hydraulic cylinders 331, 332, 333, and 334 are retracted, the two first inner molds 310 are close to each other in the AB direction.

The second inner mold driving device is in driving connection with the second inner mold 320, and is used for driving the second inner mold 320 to move back and forth between the two first inner molds 310 along the CD direction. The second inner mold 320 is moved in the direction D so that the second inner mold forming surface 320a is press-fitted on the inner end surface 120b of the rubber product 100. The second inner mold 320 is moved in the C direction so that the second inner mold forming surface 320a is disengaged from the inner end surface 120b of the rubber article 100. It will be appreciated that the second internal mold drive may be implemented in a variety of configurations, such as a hydraulic drive, a pneumatic drive, or a lead screw nut drive, among others. In this embodiment, the second internal mold driving device is a hydraulic driving device. The second internal mold driving means includes a hydraulic cylinder 341. The hydraulic cylinder 341 is provided on a side of the second inner die 320 facing away from the second inner die forming surface 320 a. A piston rod of the hydraulic cylinder 341 is connected to the second inner die 320. The cylinder body of the hydraulic cylinder 341 is fixedly provided. The second inner mold 320 moves in the D direction when the piston rod of the hydraulic cylinder 341 is extended, and the second inner mold 320 moves in the C direction when the piston rod of the hydraulic cylinder 341 is retracted.

The two first inner molds 310 are separated from each other in the AB direction, and the second inner mold 320 is moved in the D direction until the first inner mold contact surface 310b and the second inner mold contact surface 320b are attached to each other. At this time, the first inner mold forming surface 310a and the second inner mold forming surface 320a form a smooth and continuous inner mold forming surface. In this case, the vulcanizing device inner mold 300 is in an operating state (both fig. 3 and 4 show a structure in which the vulcanizing device inner mold 300 is in an operating state). The inner molding surface presses the inner surface of the rubber product 100 to form the inner surface of the rubber product 100 into a predetermined shape, and vulcanizes the rubber product 100 at a high temperature. After the vulcanization of the rubber product 100 is completed, the second outer mold 220 is moved in the C direction, and the first inner mold contact surface 310b is separated from the second inner mold contact surface 320b. The two first inner molds 310 then approach each other in the direction AB, in which case the curing device outer mold 200 is in a contracted state. At this time, the first inner molding surface 310a is separated from the inner side surface 110b of the rubber product 100, and the second inner molding surface 320a is separated from the inner side surface 120b of the rubber product 100. The first internal mold driving device and the second internal mold driving device drive the internal mold 300 of the vulcanizing device to be converted into the contracted state from the working state, so that the demolding of the rubber product 100 relative to the internal mold 300 of the vulcanizing device is automatically realized. Meanwhile, when the vulcanizing device inner mold 300 is in a contracted state, demolding of the rubber product 100 relative to the vulcanizing device outer mold is facilitated, and the rubber product 100 to be processed is also facilitated to be mounted on the vulcanizing device inner mold 300.

In the present embodiment, the distance between the two first inner mold contact surfaces 310b is gradually reduced along the movement direction (D direction) in which the second inner mold 320 approaches the first inner mold contact surfaces 310b, and the distance between the two second inner mold contact surfaces 320b is also gradually reduced. In this way, when the vulcanizing device inner mold 300 is shifted from the contracted state to the working state, the cooperation between the first inner mold contact surface 310b and the second inner mold contact surface 320b can simultaneously serve as a guide, facilitating the first inner mold 310 and the second inner mold 320 to accurately move to predetermined positions, so that the first inner mold forming surface 310a and the second inner mold forming surface 320a form a smooth and continuous outer forming surface.

In the present embodiment, the first inner mold 310 includes a fixing plate 315, and four sub-outer molds, which are a sub-outer mold 311, a sub-outer mold 312, a sub-outer mold 313, and a sub-outer mold 314, which are sequentially arranged in the CD direction. The sub-outer mold 311, the sub-outer mold 312, the sub-outer mold 313, and the sub-outer mold 314 are provided on the fixing plate 315. The fixing plates 315 of the two first inner molds 310 are disposed opposite to each other. The hydraulic cylinders 331 and 332 are connected to the fixed plate 315. The first inner mold 310 forms the first inner mold forming surface 310a together by the surfaces of the four sub-outer molds, so that the manufacturing difficulty of the first inner mold 310 can be reduced. In the first inner mold 310, adjacent sub-inner molds are contacted by an inner mold limit surface 31a inclined with respect to the AB direction. The inner mold limiting surface 31a is inclined relative to the AB direction, and can play a role in guiding during the assembly process of the sub-inner molds, so that the sub-inner molds can be tightly attached to each other, and the outer sides of the sub-inner molds form a smooth and continuous first inner mold forming surface 310a.

In this embodiment, a first inner mold locking structure 350 for detachably connecting with the outer mold of the vulcanizing device in an operating state is provided on each of the first inner mold 310 and the second inner mold 320. The first inner mold locking structure 350 is connected to the outer mold of the curing apparatus when the inner mold 300 of the curing apparatus is in an operating state, thereby maintaining the size of the cavity formed by the inner mold 300 of the curing apparatus and the outer mold of the curing apparatus and continuously applying pressure to the rubber product 100. Further, in the present embodiment, four first inner mold locking structures 350 are provided at the upper end of the fixing plate 315, and one first inner mold locking structure 350 is provided at the upper end of the second inner mold 320. Four holes are formed at the upper end of the fixing plate 315 to form four first inner mold locking structures 350 on the fixing plate 315. A hole is formed at the upper end of the second inner mold 320 to form a first inner mold locking structure 350 on the second inner mold 320. In the working state, the first inner mold locking structure 350 is used to cooperate with a locking structure on an outer mold of a vulcanizing device, so as to maintain the inner mold 300 of the vulcanizing device in the working state, and achieve locking between the inner mold 300 of the vulcanizing device and the outer mold of the vulcanizing device.

In this embodiment, a second inner mold locking structure 360 is also included in connection with the first inner mold 310. In the contracted state, the two first inner molds 310 are detachably connected by the second inner mold locking structure 360. The second inner mold locking structure 360 includes two connection plates 361 and a first inner mold locking cylinder 362, and the two connection plates 361 are respectively connected to the two first inner molds 310. The two connection plates 361 are staggered up and down. The first inner mold locking cylinder 362 is fixed to one of the connecting plates 361. Both connecting plates 361 start to have through holes. In the contracted state, the through holes on the two connecting plates 361 are opposite, and the piston rods of the first inner mold locking cylinders 362 penetrate through the through holes on the two connecting plates 361, so that the two first inner molds 310 are prevented from moving along the AB direction, the inner mold 300 of the vulcanizing device is maintained in the contracted state, and the error movement of the inner mold 300 of the vulcanizing device is avoided.

Further, in the present embodiment, the inner mold 300 of the vulcanizing device further includes a support base 370, and a first inner mold rail 371 and a second inner mold rail 372 are disposed on the support base 370. The first inner mold rail 371 extends in the AB direction, and the first inner mold 310 is slidably engaged with the first inner mold rail 371. The second inner mold rail 372 extends in the CD direction, and the second inner mold 320 slidably engages the second inner mold rail 372. The first and second inner mold rails 371 and 372 guide the first and second inner molds 310 and 320, respectively, so that the first inner mold 310 can accurately move in the AB direction and the second inner mold 320 can accurately move in the CD direction. Five internal mold fixing columns 373 are further arranged on the supporting seat 370, and the cylinder bodies of the hydraulic cylinder 331, the hydraulic cylinder 332, the hydraulic cylinder 333, the hydraulic cylinder 334 and the hydraulic cylinder 341 are fixedly connected with the five internal mold fixing columns 373 respectively.

In summary, the inner mold 300 of the vulcanizing device provided in this embodiment can be automatically switched between the working state and the shrinking state, so as to automatically realize the demolding of the rubber product 100 with respect to the inner mold 300 of the vulcanizing device. Meanwhile, when the inner mold 300 of the vulcanizing device is in a contracted and opened state, demolding of the rubber product 100 relative to the outer mold of the vulcanizing device is facilitated, and the rubber product 100 to be processed is conveniently mounted on the inner mold 300 of the vulcanizing device.

Example 3:

referring to fig. 4, fig. 4 is a schematic perspective view of a vulcanizing device 010 according to the present embodiment. The vulcanizing device 010 includes the vulcanizing device outer mold 200 described in example 1 and the vulcanizing device inner mold 300 described in example 2. The curing device inner mold 300 is located between the two first outer molds 210, and the first outer mold 210 is opposite to the first inner mold 310; the second outer mold 220 is opposite to the second inner mold 320. Thereby, a cavity 011 for accommodating the rubber product 100 (shown in fig. 1a, 1b and 1 c) is formed between the vulcanizing device outer mold 200 and the vulcanizing device inner mold 300. In fig. 4, the outer mold 200 of the vulcanizing device is in an open state, and the inner mold 300 of the vulcanizing device is in an operating state.

The vulcanizing device 010 operates as follows. First, the curing apparatus outer mold 200 is switched to the open state, and the curing apparatus inner mold 300 is switched to the contracted state, at which time the volume of the cavity 011 is maximized. In this way, the rubber product 100 can be easily put into the cavity 011 and the rubber product 100 is put on the vulcanizing device inner mold 300. Then, the vulcanizing device inner mold 300 is shifted to the working state. Then, the outer mold 200 of the vulcanizing device is switched to the working state, and the outer molding surface of the outer mold 200 of the vulcanizing device presses the outer surface of the rubber product 100, and the inner molding surface of the inner mold 300 of the vulcanizing device presses the inner surface of the rubber product 100. High temperature steam is fed into the curing apparatus outer mold 200 and the curing apparatus inner mold 300 through the first outer mold steam port 281, the second outer mold steam port 282, the first inner mold steam port 381, and the second inner mold steam port 382, thereby shaping and curing the rubber product 100. After the completion of vulcanization, the vulcanizing device outer mold 200 is switched to the open state, the vulcanizing device inner mold 300 is switched to the contracted state, and the automatic demolding of the rubber product 100 is completed, and since the volume of the cavity 011 is at this time maximum, the rubber product 100 can be easily taken out from the molding cavity 011.

In this embodiment, when the curing device outer mold 200 and the curing device inner mold 300 are in operation, the first outer mold locking cylinders 252 are inserted into the corresponding first inner mold locking structures 350 (holes) to maintain the size of the cavity 011 and apply a continuous pressure to the rubber article 100.

It should be noted that, the specific working process of the outer mold 200 and the inner mold 300 of the vulcanizing device may refer to the descriptions of embodiment 1 and embodiment 2, and this embodiment is not repeated.

Example 4:

please refer to fig. 5a and fig. 5b. Fig. 5a is a schematic perspective view of a multi-station vulcanizing device 020 according to the present embodiment. Fig. 5b is a left side view of the multi-station vulcanizing device 020 according to the present embodiment.

The multi-station vulcanizing device 020 includes one vulcanizing device outer mold 200 described in example 1, two vulcanizing device inner molds 300 described in example 2, one second outer mold 220 described in example 1, and a movable carrier 500. The movable supporting platform 500 is disposed between the two first exterior molds 210, and the movable supporting platform 500 is driven by a power device (not shown) to move back and forth in the CD direction. The two vulcanizing device inner molds 300 and the two second outer molds 220 are alternately arranged on the moving carrier 500 at intervals in the CD direction; the second inner mold 320 of the curing device inner mold 300 is opposite to the adjacent second outer mold 220. The multi-station vulcanizing device 020 thus formed has two stations.

When the moving carrier 500 drives one of the inner molds 300 of the vulcanizing device to move between the two first outer molds 210, the second outer mold 220 adjacent to the inner mold 300 of the vulcanizing device forms the outer mold 200 of the vulcanizing device together with the two first outer molds 210, and the outer mold 200 of the vulcanizing device forms the vulcanizing device 010 described in embodiment 3 together with the inner mold 300 of the vulcanizing device. The vulcanizing device 010 may mold the rubber product 100 by vulcanization and may simultaneously sheath the unprocessed rubber product 100 on the other vulcanizing device inner mold 300. After the vulcanization molding of the rubber product 100 is completed by the vulcanization device 010, the moving bearing platform 500 drives the vulcanization device inner mold 300 between the two first outer molds 210 to move outside the two first outer molds 210, the vulcanized and molded rubber product 100 can be removed from the vulcanization device inner mold 300, and a new rubber product 100 is sleeved on the vulcanization device inner mold 300. At the same time, the other vulcanizing device inner mold 300 is brought between the two first outer molds 210 by the moving carrying platform 500, thereby vulcanizing and molding the raw rubber article 100 fitted thereon. In this way, the mounting and dismounting of the rubber product 100 and the vulcanization molding of the rubber product 100 can be simultaneously performed, and the working efficiency is greatly improved.

It should be noted that one vulcanizing device outer mold 200, two vulcanizing device inner molds 300, and one second outer mold 220 are included in the present embodiment. In other embodiments, the multi-station curing apparatus 020 may comprise one curing apparatus outer mold 200, N curing apparatus inner molds 300, and N-1 second outer molds 220, N being a positive integer of 2 or more.

In this embodiment, the multi-station vulcanizing device 020 further includes a lifting support 600 and a platform support 700. The sectional shape of the landing support 600 is U-shaped, and the landing support 600 extends in the CD direction and is located between the two second outer molds 220. The moving carrier 500 is brought into contact with the upper surfaces of both ends of the landing support 600 in the width direction by the rollers 510, thereby moving back and forth in the CD direction. The platform support 700 penetrates the bottom of the landing support 600. The landing support 600 is configured to move up and down along the platform support 700 under the driving of a power device (not shown). When the landing support 600 moves upward along the platform support 700, the upper surfaces of both ends of the landing support 600 in the width direction contact the rollers 510 of the movable carrier 500 and support the movable carrier 500 such that the movable carrier 500 is separated from the platform support 700. At this time, the mobile carrier platform 500 may be moved back and forth in the CD direction, switching between the two stations. When the landing support 600 moves downward along the platform support 700, the movable loading platform 500 falls on the platform support 700, and the upper surfaces of both ends of the landing support 600 in the width direction are separated from the rollers 510 of the movable loading platform 500. At this time, the movable supporting platform 500 cannot move back and forth in the CD direction, and the relative positions of the outer mold 200 and the inner mold 300 are not changed, so that the mounting and dismounting of the rubber product 100 and the vulcanization molding of the rubber product 100 can be performed, and the working stability is improved.

Further, in the present embodiment, a guide frame 400 extending in the CD direction is further included, and a lifting mechanism 800 for moving back and forth in the CD direction is provided on the guide frame 400. The lifting mechanism 800 is used for mounting and dismounting the rubber product 100, and improves the automation degree of the multi-station vulcanizing device 020.
