Description

Technical Field

[0001] The utility model relates to the technical field of rubber sealing rings, in particular to hot pressing and cutting equipment for producing rubber sealing rings. Background Art

[0002] Rubber sealing ring is a commonly used mechanical component, mainly used to prevent the leakage and penetration of liquids, gases, dust and other substances. They are usually made of rubber materials. Because rubber has excellent elasticity, wear resistance, oil resistance, acid and alkali resistance and other properties, it can adapt to different working environments and working conditions. When producing rubber sealing rings, hot pressing and cutting equipment will be used. Hot pressing and cutting is a method of processing materials using high temperature and pressure. It is mainly used for the processing of plastic films, rubber, metal foils and other materials.

[0003] When processing existing rubber sealing rings, hot pressing and cutting equipment is used. The rubber surface layer is placed between the hot pressing and cutting equipment and cut by a hot pressing and cutting knife. When processing the rubber sealing ring, it is inconvenient to clean the cut waste, resulting in manual cleaning of the waste and low processing efficiency.

[0004] Therefore, we propose a hot pressing and cutting device for rubber sealing ring production, which can clean up the waste after hot pressing and cutting of rubber sealing rings to improve the processing efficiency. Utility Model Content

[0009] Preferably, the first magnetic plate and the second magnetic plate are magnetically attracted to each other, and the third magnetic plate and the fourth magnetic plate are magnetically attracted to each other, under which the fitting state between the scraper and the top surface of the lower mold base can be controlled.

[0010] Preferably, the outer wall of the L-shaped plate is slidably arranged with respect to the inner side of the limit frame, and the first separation hook and the second separation hook are arranged with an inclined surface at one end away from the top surface of the lower mold base, so as to separate the first magnetic plate, the second magnetic plate, the third magnetic plate and the fourth magnetic plate which are magnetically attracted to each other.

[0011] Preferably, the outer wall of the extrusion block is set in an arc surface, and the outer wall of the extrusion plate is set in an arc surface. The extrusion block contacts the arc surface of the extrusion plate. Under its restriction, the reciprocating extrusion plate squeezes the extrusion block, and cooperates with the spring to make the striking plate produce a striking effect.

[0012] Preferably, one end of the spring is fixedly installed on the top surface of the fixed block, and the end of the spring away from the fixed block is fixedly installed on the end of the push rod away from the push plate. When the extrusion plate and the extrusion block are no longer extruded, the impact plate hits the bottom of the lower mold base under the action of the spring elasticity.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The hot pressing and cutting equipment for producing rubber sealing rings is composed of a cleaning component as one of its components. When the rubber sealing ring needs to be hot pressed and cut, the rubber surface layer is placed on the top surface of the lower die seat. At this time, the cylinder is started to push the upper die seat downward so that the upper die seat contacts the lower die seat for hot pressing and cutting. Since the connecting plate is hingedly connected to the bottom of the upper die seat, and the end of the connecting plate away from the upper die seat is hingedly connected to the top surface of the L-shaped plate, the upper die seat moving downward pushes the connecting plate and drives the L-shaped plate to slide on the top surface of the lower die seat. At this time, the third magnetic plate and the fourth magnetic plate are magnetically attracted to each other, so that the scraper does not contact the top surface of the lower die seat and does not scrape the laid rubber surface layer. When the upper die seat and the lower die seat have completed the hot pressing and cutting of the rubber surface layer, the third magnetic plate fixedly installed on the top surface of the scraper contacts and squeezes the second separation hook. Since the outer wall of the second separation hook is arranged in an inclined surface, the third magnetic plate is separated from the fourth magnetic plate, and under the action of gravity The scraper slides on the outer wall of the limit column, driving the second magnetic plate and the third magnetic plate to slide in the direction of the first magnetic plate, so that the second magnetic plate and the first magnetic plate are magnetically attracted to each other. At this time, the scraper is in contact with the top surface of the lower mold base, and when the upper mold base moves upward, the L-shaped plate and the scraper are driven to move in the direction of the first separation hook through the connecting plate. Due to the sliding arrangement of the outer wall of the L-shaped plate and the inner side of the limit frame, under its restriction, the L-shaped plate can always be in contact with the top surface of the lower mold base. The scraper moving in the direction of the first separation hook cleans the debris cut by hot pressing, and the contacting scraper can clean the debris attached to the top surface of the lower mold base in time to avoid its adhesion. When the second magnetic plate fixedly installed at the bottom of the scraper contacts the first separation hook, under the restriction of the first separation hook set on the inclined surface, the second magnetic plate is separated from the first magnetic plate, so that the third magnetic plate and the fourth magnetic plate are magnetically attracted to each other, so as to avoid the scraper pushing the laid rubber surface layer when the upper mold base and the lower mold base are hot pressed and cut.

[0015] 2. The hot pressing and cutting equipment for producing rubber sealing rings is composed of a demoulding component as one of its components. When the upper die seat performs hot pressing and cutting on the lower die seat, the rubber sealing ring falls through the die hole on the top surface of the lower die seat to be demoulded. During the demoulding process, part of the rubber sealing ring will be stuck in the die hole and needs to be assisted in unloading. When the upper die seat moves up and down, it can drive the L-shaped plate to reciprocate on the top surface of the lower die seat. Under its restriction, the extrusion plate fixedly installed at one end of the L-shaped plate away from the first magnetic plate moves accordingly, and the outer wall of the extrusion plate slides and squeezes the extrusion block fixedly installed on the top surface of the push plate, so that the push rod fixedly installed on the top surface of the push plate slides inside the fixed block, and the spring sleeved on the outer wall of the fixed block is compressed accordingly. When the extrusion plate and the extrusion block are not extruded, under the action of the spring elasticity, the striking plate fixedly installed on the outer wall of the push plate strikes the bottom of the lower die seat, and the rubber sealing ring in the die hole of the lower die seat is shaken off, so as to achieve the purpose of auxiliary unloading.

DETAILED DESCRIPTION

[0023] In order to have a clearer understanding of the technical features, purposes and effects of the utility model, the specific implementation methods of the utility model are now described with reference to the accompanying drawings.

[0024] Example 1

[0025] The preferred embodiment of the hot pressing and cutting device for producing rubber sealing rings provided by the utility model is as follows Figures 1 to 6 As shown: A hot pressing and cutting device for producing rubber sealing rings, comprising a lower die base 1;

[0026] A support leg 2 is fixedly installed at the bottom of the lower die base 1;

[0027] A limit rod 3 is fixedly installed on the top surface of the lower die base 1;

[0028] An upper die seat 4 is slidably arranged on the outer wall of the limiting rod 3;

[0029] A cylinder 5 is fixedly mounted on the top surface of the upper die base 4;

[0030] A top plate 6 is fixedly mounted on one end of the cylinder 5 away from the upper die base 4;

[0031] And a processing component 7 is arranged below the top plate 6, the processing component 7 includes a cleaning component 71 arranged below the top plate 6, the cleaning component 71 includes a connecting plate 711 hingedly connected to the bottom surface of the upper mold base 4, the connecting plate 711 is hingedly connected to an L-shaped plate 712 at one end away from the upper mold base 4, a first magnetic plate 713 is fixedly installed on the top surface of the L-shaped plate 712, a limiting column 714 is fixedly installed on the top surface of the first magnetic plate 713, a fourth magnetic plate 721 is fixedly installed on the end of the limiting column 714 away from the first magnetic plate 713, a scraper 715 is slidably arranged on the outer wall of the limiting column 714, a second magnetic plate 716 is fixedly installed on the bottom of the scraper 715, a third magnetic plate 717 is fixedly installed on the top surface of the scraper 715, a first separation hook 718 is fixedly installed on the top surface of the lower mold base 1, a second separation hook 719 is arranged on the left side of the first separation hook 718, and a limiting frame 720 is fixedly installed on the outer wall of the lower mold base 1.

[0032] In this embodiment, when the rubber sealing ring needs to be hot-pressed and cut, the rubber surface layer is placed on the top surface of the lower die base 1. At this time, the cylinder 5 is started to push the upper die base 4 downward so that the upper die base 4 contacts the lower die base 1 to perform hot-pressing and cutting work. Since the connecting plate 711 is hingedly connected to the bottom of the upper die base 4, and the end of the connecting plate 711 away from the upper die base 4 is hingedly connected to the top surface of the L-shaped plate 712, the upper die base 4 moving downward pushes the connecting plate 711 and drives the L-shaped plate 712 to slide on the top surface of the lower die base 1. At this time, the third magnetic plate 717 and the fourth magnetic plate 717 are connected. The plates 721 are magnetically attracted to each other, so that the scraper 715 does not contact the top surface of the lower mold base 1, and does not scrape the laid rubber surface layer. When the upper mold base 4 and the lower mold base 1 have completed the hot pressing and cutting of the rubber surface layer, the third magnetic plate 717 fixedly installed on the top surface of the scraper 715 is in contact and squeezed with the second separation hook 719. Since the outer wall of the second separation hook 719 is arranged in an inclined surface, the third magnetic plate 717 is separated from the fourth magnetic plate 721. Under the action of gravity, the scraper 715 slides on the outer wall of the limiting column 714, driving the second magnetic plate 716 to separate from the third magnetic plate 717. The three magnetic plates 717 slide toward the first magnetic plate 713, so that the second magnetic plate 716 and the first magnetic plate 713 are magnetically attracted. At this time, the scraper 715 is in contact with the top surface of the lower mold base 1. When the upper mold base 4 moves upward, the L-shaped plate 712 and the scraper 715 are driven to move toward the first separation hook 718 through the connecting plate 711. Since the outer wall of the L-shaped plate 712 is slidably arranged with the inner side of the limit frame 720, under its restriction, the L-shaped plate 712 can always be in contact with the top surface of the lower mold base 1 to move toward the first separation hook 718. 715 cleans up the debris from hot pressing and cutting, and the fitted scraper 715 can clean up the debris attached to the top surface of the lower mold base 1 in time to prevent it from sticking. When the second magnetic plate 716 fixedly installed at the bottom of the scraper 715 contacts the first separation hook 718, the second magnetic plate 716 is separated from the first magnetic plate 713 under the restriction of the first separation hook 718 set on the inclined surface, so that the third magnetic plate 717 and the fourth magnetic plate 721 are magnetically attracted to each other, so as to prevent the scraper 715 from pushing the laid rubber surface layer when the upper mold base 4 and the lower mold base 1 are hot pressed and cut.

[0033] Furthermore, the first magnetic plate 713 and the second magnetic plate 716 are magnetically attracted to each other, and the third magnetic plate 717 and the fourth magnetic plate 721 are magnetically attracted to each other. Under their restriction, the fitting state between the scraper plate 715 and the top surface of the lower mold base 1 can be controlled.

[0034] Furthermore, the outer wall of the L-shaped plate 712 is slidably arranged with respect to the inner side of the limit frame 720, and the first separation hook 718 and the second separation hook 719 are arranged at an inclined surface at one end away from the top surface of the lower mold base 1, so as to separate the first magnetic plate 713, the second magnetic plate 716, the third magnetic plate 717 and the fourth magnetic plate 721 which are magnetically attracted to each other.

[0035] Example 2

[0036] Based on Example 1, a preferred embodiment of a hot pressing and cutting device for producing a rubber sealing ring provided by the utility model is as follows: Figures 1 to 6 As shown: the demolding assembly 73 includes an extrusion plate 736 fixedly installed on the end of the L-shaped plate 712 away from the first magnetic plate 713, a fixed block 731 is fixedly installed on the outer wall of the lower mold base 1, a push rod 732 is slidably arranged inside the fixed block 731, a spring 733 is sleeved on the outer wall of the push rod 732, a push plate 734 is fixedly installed on the end of the push rod 732, an extrusion block 735 is fixedly installed on the top surface of the push plate 734, and a striking plate 737 is fixedly installed on the outer wall of the push plate 734.

[0037] In this embodiment, when the upper die base 4 is hot-pressing and cutting the lower die base 1, the rubber sealing ring falls through the die hole on the top surface of the lower die base 1 to be demolded. During the demolding process, part of the rubber sealing ring will be stuck inside the die hole, and it is necessary to assist in unloading. When the upper die base 4 moves up and down, it can drive the L-shaped plate 712 to reciprocate on the top surface of the lower die base 1. Under its restriction, the extrusion plate 736 fixedly installed at one end of the L-shaped plate 712 away from the first magnetic plate 713 moves accordingly, and the outer wall of the extrusion plate 736 is aligned with the push plate 73 The extrusion block 735 fixedly mounted on the top surface slides and squeezes, so that the push rod 732 fixedly mounted on the top surface of the push plate 734 slides inside the fixed block 731, and the spring 733 sleeved on the outer wall of the fixed block 731 is compressed accordingly. When the extrusion plate 736 and the extrusion block 735 are not extruded, the striking plate 737 fixedly mounted on the outer wall of the push plate 734 strikes the bottom of the lower die base 1 under the elastic action of the spring 733, so that the rubber sealing ring in the die hole of the lower die base 1 is shaken off, so as to achieve the purpose of auxiliary discharge.

[0038] Furthermore, the outer wall of the extrusion block 735 is arranged in an arc surface, and the outer wall of the extrusion plate 736 is arranged in an arc surface. The extrusion block 735 contacts the arc surface of the extrusion plate 736. Under the restriction, the reciprocating extrusion plate 736 squeezes the extrusion block 735, and cooperates with the spring 733 to make the striking plate 737 produce a striking effect.

[0039] In addition, one end of the spring 733 is fixedly installed on the top surface of the fixed block 731, and the end of the spring 733 away from the fixed block 731 is fixedly installed on the end of the push rod 732 away from the push plate 734. When the extrusion plate 736 and the extrusion block 735 are no longer extruded, the impact plate 737 impacts the bottom of the lower mold base 1 under the elastic action of the spring 733.

[0040] The above is only an illustrative specific implementation method of the utility model, and is not intended to limit the scope of the utility model. Any equivalent changes and modifications made by any technician in this field without departing from the concept and principle of the utility model should fall within the scope of protection of the utility model. It should also be noted that the various components of the utility model are not limited to the above-mentioned overall application. The various technical features described in the specification of the utility model can be selected one by one or multiple ones can be selected and used in combination according to actual needs. Therefore, the utility model should naturally cover other combinations and specific applications related to the utility model points of this case.
