Description

Technical Field

[0001] The embodiments of the present disclosure relate to the technical field of rubber processing, and in particular, to a flat vulcanizing machine for rubber processing production. Background Art

[0002] In the rubber processing industry, the flat plate vulcanizer is a key equipment for vulcanizing and molding rubber products. After vulcanization is completed, the traditional rubber processing and production flat plate vulcanizer has a relatively simple and crude way of separating the rubber pad from the mold. It is often separated manually or by a relatively simple mechanical ejection method, which is not only inefficient, but also easily causes deformation and damage to the rubber pad, seriously affecting product quality. During the separation process, due to the lack of effective fixing measures, the rubber pad is prone to displacement when the mold is separated, resulting in difficulty in ensuring product dimensional accuracy and a high defective rate.

[0003] In addition, traditional equipment also has obvious defects in dealing with the rubber flash produced around the rubber pad after vulcanization. Usually it relies on manual trimming, which not only consumes a lot of manpower and time, but also the trimming accuracy and quality are difficult to guarantee, and cannot meet the needs of large-scale and high-efficiency production. At the same time, the manual trimming process is also prone to secondary damage to the rubber pad itself, further reducing product quality. Summary of the invention

[0004] In order to overcome the above-mentioned defects, the embodiments of the present disclosure provide a flat plate vulcanizer for rubber processing and production, which solves the technical problem in the prior art that film flash will be present around the finished rubber pad after vulcanization by the flat plate vulcanizer.

[0008] For example, at least one embodiment of the present disclosure provides a flat plate vulcanizing machine for rubber processing production, which further includes: A stripping plate, the stripping plate being slidably disposed on the cover plate, the stripping plate having a plurality of staggered holes, and a blade portion being provided on one side of the staggered holes; The rubber pad passes through the shear hole and then enters the staggered hole; After the stripping plate slides, the staggered holes overlap or stagger with the shear holes, and after staggering, the rubber pad is separated from the top surface of the ejector rod.

[0009] For example, in a flat plate vulcanizer for rubber processing and production provided by at least one embodiment of the present disclosure, the cover plate is rotatably arranged on the unloading rack, and further comprises: A material receiving frame, the material receiving frame is arranged on the unloading frame; after the rubber pads are separated from the top surface of the ejector rod, the cover plate rotates to make a plurality of the rubber pads fall into the material receiving frame; The second telescopic member is hingedly arranged on the unloading rack, the extended end of the second telescopic member is hingedly connected to the cover plate, and the second telescopic member is used to drive the cover plate to rotate after being extended.

[0010] For example, in a flat plate vulcanizer for rubber processing and production provided by at least one embodiment of the present disclosure, the cover plate has a second through hole, the stripping plate has an abutting inclined surface, and further includes: A connecting rod, wherein the connecting rod is slidably arranged in the second through hole, and the extended end of the second telescopic member is hinged to one end of the connecting rod; after the second telescopic member is extended, the other end of the connecting rod contacts the abutting inclined surface, driving the stripping plate to slide, so as to make the shear holes and the staggered holes staggered with each other.

[0011] For example, in a rubber processing and production plate vulcanizer provided by at least one embodiment of the present disclosure, the second through hole has an abutment surface, the end of the connecting rod away from the second telescopic member has an annular protrusion, and further includes: A limit plate, which is arranged on the unloading rack and is located below the cover plate; After the second telescopic member is retracted, it drives the annular protrusion to abut against the abutting surface, so that the cover plate is rotated and tightly abutted against the limiting plate.

[0012] For example, at least one embodiment of the present disclosure provides a flat plate vulcanizing machine for rubber processing production, which further includes: An elastic member, two ends of which act on the cover plate and the stripping plate respectively, for providing a force for resetting the stripping plate so that the staggered holes overlap with the shear holes.

[0013] For example, in a flat-plate vulcanizer for rubber processing and production provided in at least one embodiment of the present disclosure, the lower mold also has a plurality of air holes, and the plurality of air holes are located around the molding hole.

[0014] For example, at least one embodiment of the present disclosure provides a flat plate vulcanizing machine for rubber processing production, which further includes: A top plate, which is vertically slidably disposed on the unloading rack and is located below the sliding plate; The top plate has a plurality of abutment protrusions.

[0024] like Figure 1 to Figure 9As shown, it shows a flat vulcanizer for rubber processing and production in one embodiment of the present disclosure, which is used for vulcanizing and molding a rubber pad 1. After the vulcanization, the rubber pad 1 has rubber flash 101 around it, including a vulcanizing body 2; a feed rack 3 is arranged on one side of the vulcanizing body 2; a lower mold 4 is horizontally slidably arranged on the vulcanizing body 2, and the lower mold 4 is close to the vulcanizing body 2 or the feed rack 3 after horizontal sliding; the lower mold 4 has a plurality of molding holes 401; there are a plurality of ejector pins 5, and the ejector pins 5 are vertically slidably arranged in the molding holes 401, and the top surfaces of the ejector pins 5 and the inner walls of the molding holes 401 form a vulcanization space 501; a cover plate 6 is arranged on the feed rack 3; after the lower mold 4 slides close to the feed rack 3, the lower mold 4 is located below the cover plate 6, and the cover plate 6 has a plurality of shear holes 601; the shear holes 601 are consistent in shape with the molding holes 401, and are used to shear the rubber flash 101 around the rubber pad 1; after the ejector pin 5 slides vertically upward, it pushes the rubber pad 1 out of the vulcanization space 501, so that the rubber pad 1 passes through the shear holes 601.

[0025] For example, Figure 1-Figure 3 As shown, in order to solve the technical problem that film flash will be present around the finished rubber pad after vulcanization by a flat vulcanizer in the prior art, a flat vulcanizer for rubber processing and production is designed. A dovetail groove guide rail structure is used between the lower mold 4 and the vulcanization body 2 to achieve horizontal sliding connection. The dovetail groove guide rail has good guiding property and stability, and can effectively prevent the lower mold 4 from deflecting or shaking during the sliding process. On the lower mold 4, a number of forming holes 401 are processed according to production requirements, and the shapes and sizes of these forming holes 401 match the specifications of the target rubber pad 1.

[0026] A vertical guide groove is provided inside the vulcanizing body 2 corresponding to the position of each forming hole 401. The push rod 5 is vertically slidably connected by cooperating with the guide groove, ensuring that the push rod 5 always remains vertical and moves smoothly during the up and down movement. The top of the push rod 5 and the inner wall of the forming hole 401 together form a vulcanizing space 501 for placing rubber raw materials.

[0027] The cover plate 6 is installed on the unloading rack 3 through a cantilever bracket, and its position is adjusted. When the lower mold 4 slides horizontally to the bottom of the unloading rack 3, the cover plate 6 is just located above the lower mold 4, and the shearing holes 601 on the cover plate 6 correspond one to one with the forming holes 401 of the lower mold 4, and the shapes of the two are exactly the same.

[0028] Specifically, first, the operator places the rubber raw material in the vulcanization space 501 formed by the molding hole 401 of the lower mold 4 and the ejector 5. Then, the vulcanization body 2 is started, and the heating and pressurizing device inside the vulcanization body 2 starts to work to vulcanize and mold the rubber raw material.

[0029] After vulcanization is completed, the lower mold 4 slides horizontally along the dovetail groove guide rail to the bottom of the unloading rack 3 under the action of an external drive (such as a motor-driven screw mechanism or a traction cylinder). At this time, the push rod 5 slides vertically upward along the forming hole 401 under the push of an external drive (such as a hydraulic telescopic device). As the push rod 5 rises, the rubber pad 1 gradually leaves the vulcanization space 501 and passes through the shear hole 601 on the cover plate 6. Since the shear hole 601 is consistent in shape with the forming hole 401, the excess rubber flash 101 around the rubber pad 1 is sheared off at the moment the rubber pad 1 passes through.

[0030] The advantage is that the design of pushing the rubber pad 1 through the shear hole 601 by the push rod 5 realizes the automatic shearing of the flash of the rubber pad 1. This process does not require manual trimming, greatly improves production efficiency, reduces labor costs and time costs, and makes the production process more efficient and smooth.

[0031] In some examples, there is a gap 602 between the cover plate 6 and the lower mold 4, and the sheared rubber flash 101 is located in the gap 602. It also includes a sliding plate 7, which is horizontally slidably set on the vulcanization body 2, and the lower mold 4 is horizontally slidably set on the vulcanization body 2 through the sliding plate 7; the lower mold 4 is also vertically slidably set relative to the sliding plate 7; after the lower mold 4 slides vertically, it approaches the cover plate 6 to reduce the gap 602; the sliding plate 7 has a plurality of first through holes 701, and the first through holes 701 coincide with the positions of the forming holes 401, and the end of the push rod 5 away from the lower mold 4 slides vertically in the first through hole 701.

[0032] For example, Figure 2-Figure 3 As shown, on the horizontal plane of the vulcanizing body 2, the sliding plate 7 cooperates with the guide rail through the dovetail slider at the bottom to achieve horizontal sliding. Vertical guide posts are arranged around the bottom of the lower mold 4, and guide sleeves are provided at corresponding positions on the sliding plate 7. The lower mold 4 achieves vertical sliding relative to the sliding plate 7 through the cooperation of the guide posts and the guide sleeves. On the sliding plate 7, a plurality of first through holes 701 are processed according to the positions of the forming holes 401 of the lower mold 4 to ensure that the first through holes 701 completely overlap with the forming holes 401.

[0033] Specifically, after the rubber pad 1 is vulcanized, the lower mold 4 together with the sliding plate 7 slides horizontally to the bottom of the unloading rack 3 under the action of the lead screw mechanism driven by the motor, and then the vertical drive device is started to drive the lower mold 4 to rise vertically relative to the sliding plate 7. After the lower mold 4 and the cover plate 6 clamp the rubber flash 101, the vertical drive is stopped. At this time, the push rod 5, driven by the hydraulic drive device, slides vertically upward along the molding hole 401, passes through the first through hole 701, pushes the rubber pad 1 out of the vulcanization space 501 and passes through the shear hole 601 on the cover plate 6, and completes the flash shearing.

[0034] The advantage is that the vertical sliding design of the lower mold 4 relative to the sliding plate 7 enables the gap 602 between the cover plate 6 and the lower mold 4 to be adjusted and clamped according to the thickness and flash conditions of different rubber pads 1, effectively improving the quality and accuracy of flash shearing and reducing the loss of the rubber pad 1. The setting of the first through hole 701 provides a stable movement channel for the ejector 5, while not affecting the vertical adjustment of the lower mold 4, facilitating the movement control of the ejector 5, and ensuring the smooth demoulding and flash shearing of the rubber pad 1.

[0035] In some examples, the lower mold 4 also has a snap-in protrusion 402, and also includes a lifting frame 8, which is vertically slidably set on the unloading frame 3, and the lifting frame 8 has a snap-in groove 801; after the sliding plate 7 slides horizontally close to the unloading frame 3, the snap-in protrusion 402 enters the snap-in groove 801; the first telescopic member 9 is set on the unloading frame 3, which is used to drive the lifting frame 8 to slide vertically, so that the lower mold 4 is close to or away from the cover plate 6.

[0036] For example, Figure 4-Figure 5 As shown, on both sides of the material discharging rack 3, the lifting rack 8 realizes vertical sliding through the first telescopic member 9 (such as a cylinder). On the side of the lifting rack 8, a clamping groove 801 matching the clamping protrusion 402 of the lower mold 4 is provided. Specifically, the clamping protrusion 402 of the lower mold 4 is aligned with the clamping groove 801 of the lifting rack 8. When the sliding plate 7 drives the lower mold 4 to slide horizontally close to the material discharging rack 3, the clamping protrusion 402 automatically falls into the clamping groove 801, realizing the vertical clamping of the lower mold 4 and the lifting rack 8. When it is necessary to raise the lower mold 4 to clamp the rubber flash 101 with the cover plate 6, the first telescopic member 9 is started to drive the lifting rack 8 and the lower mold 4 to rise vertically until the lower mold 4 and the cover plate 6 clamp the rubber flash 101.

[0037] The advantage is that the gap 602 between the lower mold 4 and the cover plate 6 can be quickly adjusted, which greatly improves the operating efficiency of the equipment and reduces the adjustment time.

[0038] In some examples, a stripping plate 10 is further included, which is slidably disposed on the cover plate 6, and has a plurality of staggered holes 1001, and a blade portion is provided on one side of the staggered holes 1001; the rubber pad 1 passes through the shear hole 601 and enters the staggered hole 1001; after the stripping plate 10 slides, the staggered hole 1001 overlaps or staggers with the shear hole 601, and after staggering, the rubber pad 1 is separated from the top surface of the top rod 5.

[0039] For example, Figure 2-Figure 3As shown, two parallel linear guide rails are installed on the surface of the cover plate 6, and the stripper plate 10 cooperates with the guide rails through the slider at the bottom to achieve horizontal sliding. A number of staggered holes 1001 are processed on the stripper plate 10, and the positions and sizes of the staggered holes 1001 correspond to the shear holes 601 on the cover plate 6, and a blade is processed on one side of the staggered holes 1001 to facilitate smooth demoulding and movement of the rubber pad 1. The driving device of the stripper plate 10 adopts a motor screw mechanism, the motor is fixed on one side of the cover plate 6, the screw is connected to the nut seat of the stripper plate 10, and the stripper plate 10 is driven to slide by the forward and reverse rotation of the motor.

[0040] Specifically, the rubber pad 1 passes through the shear hole 601 of the cover plate 6 under the push of the ejector pin 5 and enters the staggered hole 1001 of the stripping plate 10. When the rubber pad 1 needs to be separated from the top surface of the ejector pin 5 for demoulding, the stripping plate 10 is slid along the guide rail. As the stripping plate 10 slides, the staggered hole 1001 gradually intersects with the shear hole 601, and the rubber pad 1 falls off from the ejector pin 5 under the action of the stripping plate 10, completing the demoulding process.

[0041] The advantage is that the sliding design of the demoulding plate 10 realizes the automatic demoulding function of the rubber pad 1 without manual intervention, which greatly improves the production efficiency, reduces the labor intensity, and also reduces the damage to the rubber pad 1 caused by manual operation. The blade design of the staggered hole 1001 effectively avoids the problems of scratches and deformation caused by collision when the rubber pad 1 enters the staggered hole 1001, thereby ensuring the appearance quality and dimensional accuracy of the rubber pad 1.

[0042] In some examples, the cover plate 6 is rotatably arranged on the unloading rack 3, and also includes a receiving frame 11, which is arranged on the unloading rack 3; after the rubber pad 1 is separated from the top surface of the top rod 5, the cover plate 6 is rotated to make a number of rubber pads 1 fall into the receiving frame 11; the second telescopic member 12 is hingedly arranged on the unloading rack 3, and the protruding end of the second telescopic member 12 is hinged to the cover plate 6. After the second telescopic member 12 is extended, it is used to drive the cover plate 6 to rotate.

[0043] For example, Figure 6-Figure 7 As shown, the cover plate 6 is rotatably connected to the unloading rack 3 through a rotating shaft at one end, and bearings are installed at both ends of the rotating shaft to ensure the flexibility of the cover plate 6. The material receiving frame 11 is installed on the unloading rack 3 and is located at the lower position after the cover plate 6 rotates. The material receiving frame 11 can effectively collect the rubber pad 1. One end of the second telescopic member 12 (such as a hydraulic cylinder) is hinged to the unloading rack 3, and the other end is hinged to the bottom surface of the cover plate 6, and the cover plate 6 is driven to rotate through the telescopic movement of the hydraulic cylinder.

[0044] Specifically, after the rubber pad 1 is separated from the top surface of the push rod 5, the second telescopic member 12 is activated, the telescopic rod of the hydraulic cylinder is extended, and the cover plate 6 is pushed to rotate around the rotation axis. As the cover plate 6 rotates, the rubber pad 1 falls into the receiving frame 11 below under the action of gravity. When the rubber pad 1 is collected, the telescopic rod of the hydraulic cylinder is retracted, driving the cover plate 6 to rotate back to its original position, preparing for the next demoulding of the rubber pad 1.

[0045] The advantage is that the rotation of the cover plate 6 and the cooperation of the material receiving frame 11 realize the efficient collection of the rubber mat 1, reduce the scattering and loss of the rubber mat 1, and improve the cleanliness and production efficiency of the production site. The automatic collection function eliminates the link of manually collecting the rubber mat 1, greatly saves labor costs, and enables operators to devote more energy to equipment monitoring and other production links.

[0046] In some examples, the cover plate 6 has a second through hole 603, the stripping plate 10 has an abutment slope 1002, and also includes a connecting rod 13, which is slidably arranged in the second through hole 603, and the extended end of the second telescopic member 12 is hinged to one end of the connecting rod 13; after the second telescopic member 12 is extended, the other end of the connecting rod 13 contacts the abutment slope 1002, driving the stripping plate 10 to slide, so as to make the shear hole 601 and the staggered hole 1001 staggered with each other.

[0047] For example, Figure 6-Figure 7 As shown, a second through hole 603 is provided at a position corresponding to the second telescopic member 12 on the cover plate 6, and the size of the through hole is adapted to the outer diameter of the connecting rod 13. The connecting rod 13 is installed in the second through hole 603 through a guide sleeve to ensure its smooth movement. The extended end of the second telescopic member 12 is connected to one end of the connecting rod 13 in a hinged manner to ensure the stability of the connection between the two. An abutting inclined surface 1002 in contact with the other end of the connecting rod 13 is provided on the stripping plate 10, and the inclination angle of the abutting inclined surface 1002 is based on the actual operation requirements to ensure that the connecting rod 13 can effectively push the stripping plate 10 to slide.

[0048] Specifically, when the second telescopic member 12 is started and the telescopic rod of the hydraulic cylinder is extended, the connecting rod 13 is driven to slide in the second through hole 603. The other end of the connecting rod 13 contacts the abutting inclined surface 1002 of the stripping plate 10, and as the connecting rod 13 continues to move, the stripping plate 10 is pushed to slide along the linear guide rail installed on the surface of the cover plate 6. During the sliding process of the stripping plate 10, the staggered holes 1001 and the shear holes 601 on the cover plate 6 are gradually staggered, so that the demoulding operation of the rubber pad 1 from the top surface of the push rod 5 is realized. After the demoulding is completed, the second telescopic member 12 stops extending first, and the external drive first drives the push rod 5 to descend, so that one end of the push rod 5 is completely separated from the shear hole 601 on the cover plate 6, and then the second telescopic member 12 continues to extend. During the extension of the second telescopic member 12, its hinged structure with the bottom surface of the cover plate 6 will drive the cover plate 6 to rotate around the rotating shaft at one end, so that the rubber pad 1 falls into the material receiving frame 11 below.

[0049] The advantage is that, through the ingenious cooperation between the connecting rod 13 and the abutting inclined surface 1002, the sliding of the stripping plate 10 is controlled, and the degree of staggering between the staggered holes 1001 and the shearing holes 601 can be adjusted to ensure that the rubber pad 1 is smoothly demolded at the right time, thereby improving the demolding performance and stability. The second telescopic member 12 is used to simultaneously drive the cover plate 6 to rotate and the stripping plate 10 to slide, thereby reducing the number of separate driving components, simplifying the driving structure of the device, and not only reducing the manufacturing cost of the device, but also reducing the maintenance difficulty and cost, thereby improving the reliability of the device.

[0050] In some examples, the second through hole 603 has a contact surface 604, the connecting rod 13 has an annular protrusion 1301 at one end away from the second telescopic member 12, and also includes a limit plate 14, which is arranged on the unloading rack 3 and is located below the cover plate 6; after the second telescopic member 12 retracts, it drives the annular protrusion 1301 to contact the contact surface 604, so that the cover plate 6 is rotated and tightly contacted with the limit plate 14.

[0051] For example, Figure 7 As shown, on the inner wall of the second through hole 603, a matching abutment surface 604 is provided according to the size and position of the annular protrusion 1301 of the connecting rod 13. An annular protrusion 1301 with an outer diameter slightly larger than the inner diameter of the second through hole 603 is processed at one end of the connecting rod 13 away from the second telescopic member 12. The limiting plate 14 is installed on the unloading rack 3 and is located below the cover plate 6 to ensure that it is closely fitted with the lower surface of the cover plate 6 after rotation, thereby limiting the position of the cover plate 6 after rotation.

[0052] Specifically, when the second telescopic member 12 retracts, the connecting rod 13 is driven to retract together. During the retraction process, the annular protrusion 1301 on the connecting rod 13 abuts against the abutment surface 604 in the second through hole 603, driving the cover plate 6 to rotate back to its original position. When the cover plate 6 rotates back to its original position, its lower surface is tightly abutted against the limiting plate 14, effectively preventing the cover plate 6 from shaking and displacement in a non-working state, thereby ensuring the stability of the device.

[0053] The advantage is that the position of the cover plate 6 after rotation is effectively stabilized, ensuring that the cover plate 6 can be reset after each rotation, providing a stable and reliable basis for the next demoulding and processing of the rubber pad 1.

[0054] In some examples, an elastic member 15 is further included, and two ends of the elastic member 15 act on the cover plate 6 and the stripping plate 10 respectively to provide a force for restoring the stripping plate 10 so that the staggered hole 1001 coincides with the shear hole 601 .

[0055] For example, Figure 7 As shown, an elastic member 15, such as a spring, is installed between the cover plate 6 and the stripper plate 10. One end of the elastic member 15 is fixed to the cover plate 6 through a connecting member, and the other end is also fixed to the stripper plate 10. The elastic member 15 can provide sufficient restoring force for the stripper plate 10, so that the stripper plate 10 can automatically return to the initial position when no external force is applied, ensuring that the staggered holes 1001 overlap with the shear holes 601.

[0056] Specifically, after the rubber pad 1 is demoulded and blanked, the stripper plate 10 and the cover plate 6 rotate in opposite directions under the drive of the second telescopic member 12, so that the cover plate 6 contacts the limit plate 14. At this time, the elastic potential energy stored in the elastic member 15 is released, pushing the stripper plate 10 to slide along the guide rail and return to the initial position, so that the staggered hole 1001 and the shear hole 601 overlap again, preparing for the next processing of the rubber pad 1.

[0057] The advantage is that the provision of the elastic member 15 realizes the automatic resetting of the stripping plate 10, simplifies the operation process of the equipment, and reduces the manual operation steps.

[0058] The elastic member 15 acts as a buffer during the resetting process of the stripper plate 10, effectively reducing the impact force between the stripper plate 10 and the guide rail, reducing the wear of equipment components, extending the service life of related components such as the guide rail and the stripper plate 10, and reducing the maintenance cost of the equipment and the frequency of replacing components.

[0059] In some examples, the lower mold 4 further has a plurality of air holes 403 , and the plurality of air holes 403 are located around the molding hole 401 .

[0060] For example, Figure 3As shown, around the forming hole 401 of the lower mold 4, a number of air holes 403 are evenly distributed according to the size of the rubber pad 1, the requirements of the vulcanization process and the principle of uniform gas distribution. These air holes 403 are connected to the external vacuum equipment pressure blowing equipment. An electromagnetic control valve with a high-precision adjustment function is installed on the pipeline. The valve can quickly and accurately switch the gas flow direction and flow rate under the command of the equipment control system. In addition, a gas buffer device is set at the connection between the pipeline and the air hole 403 to ensure that the gas pressure entering the air hole 403 is stable and evenly distributed.

[0061] Specifically, when the rubber pad 1 is vulcanized, the control system switches the control valve to the air extraction mode, and extracts the air between the upper and lower molds through the air hole 403. The vulcanized rubber pad 1 is attached to the lower mold 4, which effectively avoids damage to the rubber pad 1 when the molds are separated, ensures the shape and size accuracy of the rubber pad 1, and improves the stability of product quality.

[0062] After the upper and lower molds 4 are completely separated, the control valve quickly switches to the blowing mode. The gas is blown into the molding hole 401 through the air hole 403. On the one hand, it pushes the rubber pad 1 and the rubber flash 101 upward to achieve preliminary demolding; on the other hand, the high-speed flowing gas can take away the heat of the rubber pad 1 and the mold surface, playing a cooling role; it not only improves the demolding efficiency and reduces manual intervention, but also can quickly reduce the temperature of the rubber pad 1 and improve production efficiency. At the same time, the cooled rubber pad 1 is not easy to deform or stick due to excessive temperature during the subsequent flash shearing process, which ensures the quality of the flash shearing.

[0063] After the operation of cutting the flash is completed, the control valve is switched back to the exhaust mode. At this time, the air hole 403 extracts air to prevent the rubber flash 101 from adhering to the lower surface of the cover plate 6 due to electrostatic adsorption or other reasons when the lower mold 4 and the cover plate 6 are separated, so as to keep the equipment clean, reduce equipment failures caused by the residual rubber flash 101, and ensure the normal operation of the equipment and the smooth progress of the next vulcanization process.

[0064] In some examples, a top plate 16 is also included, which is vertically slidably arranged on the unloading rack 3 and is located below the sliding plate 7; the top plate 16 has a plurality of abutment protrusions 1601, and after the top plate 16 slides vertically upward, the abutment protrusions 1601 enter the first through hole 701 and abut against the end of the top rod 5 away from the lower mold 4, pushing the top rod 5 to slide vertically upward in the forming hole 401.

[0065] For example, Figure 3As shown, a linear guide rail is installed in the vertical direction inside the unloading rack 3, and the top plate 16 is connected to the guide rail through a slider. On the top plate 16, a plurality of abutting protrusions 1601 are provided according to the position of the first through hole 701 on the sliding plate 7, and the height and shape of the abutting protrusions 1601 need to ensure that they can abut against the bottom of the top rod 5. The driving device of the top plate 16 adopts a hydraulic push rod, which is fixed to the bottom of the unloading rack 3, and its telescopic rod is connected to the bottom of the top plate 16.

[0066] The complete working process of the equipment is: After the vulcanization of the vulcanization body 2 is completed, the control valve of the rubber pad 1 is switched to the exhaust mode to extract the air between the upper and lower molds, so that the rubber pad 1 is closely attached to the lower mold 4 to avoid displacement and deformation during separation.

[0067] After waiting for the sliding plate 7 to drive the lower mold 4 to move onto the unloading rack 3, the first telescopic member 9 drives the lifting rack 8 to cooperate with the clamping groove 801 and the clamping protrusion 402, driving the lower mold 4 to approach the cover plate 6 and clamp the rubber flash 101 with the cover plate 6. At this time, the hydraulic push rod at the bottom of the unloading rack 3 is started to push the top plate 16 to rise along the guide rail. The abutting protrusion 1601 on the top plate 16 enters the first through hole 701 and abuts against the push rod 5, so that the rubber pad 1 located in the vulcanization space 501 is separated from the vulcanization space 501 and passes through the shearing hole 601 to shear the rubber flash 101. After the shearing is completed, the second telescopic member 12 is activated to push the connecting rod 13 to slide in the second through hole 603, so that the other end of the connecting rod 13 abuts against the abutting inclined surface 1002, thereby pushing the stripping plate 10 to slide and demoulding the rubber pad 1; At this time, the top plate 16 descends, so that the top rod 5 exits the shear hole 601, and then the second telescopic member 12 continues to extend, driving the cover plate 6 and the demoulding plate 10 to rotate, so that the demoulded rubber pad 1 enters the receiving frame 11; Afterwards, the second telescopic member 12 retracts, and the cover plate 6 and the stripper plate 10 rotate in opposite directions until the cover plate 6 contacts the limit plate 14 , and the stripper plate 10 is reset under the action of the elastic member 15 , and is ready to complete the next operation.
