Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of rubber product processing, in particular to an automatic demolding vulcanization equipment. BACKGROUND

[0002] Vulcanization is to add sulfur, carbon black, etc. in reclaimed rubber, and generate vulcanized rubber through high-pressure heating. This process is called vulcanization. Usually, vulcanized rubber is generated by using a vulcanizing machine, i.e. raw rubber is placed on the lower hot plate of the vulcanizing machine, and the raw rubber is extruded and heated at the same time by the cooperation of the upper hot plate and the lower hot plate, so as to realize vulcanization, and then the vulcanized rubber is transferred from the lower hot plate to the discharging position to realize discharging.

[0003] In the patent document with the application number 202020475955.3, a rubber joint vulcanization mold demolding device is disclosed, and specifically, the movable block movably arranged can adapt to the demolding operation of the inner core mold of different models. When the diameter of the inner core mold is large, the movable block can act outward to expand the discharging port, facilitating the falling of the inner core mold.

[0004] In the above technical solution, since the inner core mold is usually columnar, when the inner core mold extrudes the rubber product downward, the inner core mold first contacts the support assembly. At this time, since the downward pressure gradually increases, it can ensure that the rubber product can be extruded and fall. At this time, since the inner core mold contacts the support assembly as a cylindrical bottom, it is a surface contact. If the contact position of the mold and the support assembly deviates, the stress point of the rubber product will not be at the center position, which will cause the support assembly to tilt, so that the rubber product contacts the wall of the discharging plate, causing scratches on the rubber product, thereby affecting the generation quality and yield of the rubber product. Or when the mold and the support assembly contact, since the support assembly adopts a leather bowl, the leather bowl is contacted with the inner core mold. When the leather bowl tightly holds the inner core mold, the leather bowl is moved longitudinally, and the leather bowl is forced to tilt on the discharging plate. In the subsequent use process, the rubber product will contact the wall of the discharging plate and scratch the rubber product. SUMMARY

[0005] The present application provides an automatic demolding vulcanization equipment.

[0006] The technical problem solved by the present application is to solve the problem that the rubber product directly contacts the inner wall of the discharging plate, causing scratches on the rubber product.

[0007] The application can be realized by the following technical scheme: an automatic demolding vulcanization equipment comprises a lower stamping plate, a discharge groove is uniformly arranged on the lower stamping plate, a demolding tool is arranged on the discharge groove in a matched mode, the demolding tool comprises an ejection protrusion, the ejection protrusion is fixedly installed on an inclined plate, the inclined plate is in a bucket shape, a plurality of groups of stepped limiting plates are fixedly installed on the inclined plate, and the inclined plate is fixedly installed on a mounting plate.

[0008] Further technical improvements of the application are that a shielding body is installed on the inner side wall of the discharge groove, and a shielding protrusion is fixed to the side of the shielding body away from the discharge groove.

[0009] Further technical improvements of the application are that the shielding body is fixed on a rotating support base, and the rotating support base and the inner rotating shaft are rotationally connected through a torsion spring.

[0010] Further technical improvements of the application are that the inner rotating shaft is fixed on an adjusting sliding rod, and the adjusting sliding rod and the lower stamping plate are slidingly connected.

[0011] Further technical improvements of the application are that the adjusting sliding rod is fixedly installed on an adjusting sliding plate, an inner spring is fixed on the adjusting sliding plate, one end of the inner spring away from the adjusting sliding plate is fixed in an adjusting sleeve, the adjusting sleeve and the adjusting sliding plate are slidingly connected, and the adjusting sleeve is fixed on the side edge of the discharge groove.

[0012] Further technical improvements of the application are that the shielding protrusion comprises a first protrusion, a second protrusion and a third protrusion, and the sizes of the first protrusion, the second protrusion and the third protrusion gradually increase.

[0013] Further technical improvements of the application are that a connecting sleeve is fixed on the adjusting sliding rod, a limiting support base is fixed on the side edge of the connecting sleeve, a limiting groove is arranged on the limiting support base, and the limiting groove limits the rotating support base.

[0014] Further technical improvements of the application are that the demolding tool is made of rubber material, the demolding tool is fixed on an upper stamping plate, and the upper stamping plate is installed on the output end of a movable telescopic rod.

[0015] Compared with the prior art, the application has the following beneficial effects:

[0016] 1. This application first places vulcanized rubber on the feeding trough, where it is positioned on a blocking protrusion. The blocking protrusion limits the position of the vulcanized rubber. Then, a push-out protrusion moves longitudinally, initially contacting the vulcanized rubber and applying downward pressure. Under this downward pressure, the vulcanized rubber undergoes a slight positional adjustment, aligning its center with the center of the feeding trough. Continued pressure application causes a slight deformation of the vulcanized rubber, causing it to detach from the blocking protrusion and achieve automatic feeding. Because the size of the push-out protrusion is smaller than that of a traditional cylindrical rubber core, it allows for efficient feeding. The protruding part directly contacts the vulcanized rubber, avoiding direct contact between the cylindrical rubber core and the shielding protrusion. The shielding protrusion squeezes the cylindrical rubber core, and when the cylindrical rubber core is lifted upwards, it causes the shielding protrusion to tilt, resulting in direct contact between the vulcanized rubber and the inner wall of the lower plate, causing scratches. This is achieved by replacing surface contact with point contact, making the protruding part approximately point-contact with the vulcanized rubber. Because the protruding part does not contact the shielding protrusion, it will not cause the shielding protrusion to move upwards when pulled up, ensuring the stability of the shielding protrusion and thus preventing the vulcanized rubber from directly contacting the inner wall of the lower plate, ensuring the quality of the vulcanized rubber.

[0017] 2. In this application, if the vulcanized rubber has a high material hardness, resulting in a small deformation of the vulcanized rubber, it will be difficult to feed the material. Therefore, the shielding body will rotate. At this time, the torsion spring is subjected to torsional force, causing the shielding body to rotate on the internal rotating shaft. At this time, the distance between the shielding protrusions increases, which will cause the vulcanized rubber to be fed automatically. That is, the vulcanized rubber is fed through the shielding protrusions. The vulcanized rubber will not contact the inner wall of the lower plate, thus protecting the vulcanized rubber.

[0018] 3. In this application, if the hardness of the vulcanized rubber is higher and the size of the vulcanized rubber is larger, the rotation of the blocking protrusion is insufficient to realize the feeding of the vulcanized rubber. Therefore, it will push the adjusting sliding rod to move inside the adjusting sleeve. At this time, the internal spring is stressed, the distance between the blocking protrusions increases, and the blocking protrusions are pressed tightly against the vulcanized rubber to realize the feeding of the vulcanized rubber.

[0019] 4. In this application, the stepped limiting plate is used to make the stepped limiting plate and the blocking protrusion cooperate, that is, the stepped limiting plate contacts the blocking protrusion in sequence, thereby limiting the position of the demolding tool and the material discharge groove, so that the ejection protrusion can be placed in the center of the material discharge groove, ensuring the downward pressure and material discharge of the vulcanized rubber.

DETAILED DESCRIPTION

[0033] In order to further illustrate the technical means and effects adopted by the present application to achieve the predetermined inventive purpose, the specific embodiments, structures, features and effects according to the present application are described in detail below in combination with the drawings and preferred embodiments.

[0034] Referring to Figures 1-11 As shown in the drawings, an automatic demolding vulcanization equipment includes a first vulcanization mechanism 1, a second vulcanization mechanism 2 and a third vulcanization mechanism 3, wherein the first vulcanization mechanism 1, the second vulcanization mechanism 2 and the third vulcanization mechanism 3 are arranged side by side, and the first vulcanization mechanism 1, the second vulcanization mechanism 2 and the third vulcanization mechanism 3 are controlled by a control machine table 4, replacing the traditional "one-to-two" arrangement of one control machine table 4 controlling two vulcanization mechanisms, so that the above arrangement can reduce the cost, and also reduce the labor intensity of employees, so that the demolding efficiency can be improved.

[0035] Further, the first vulcanization mechanism 1, the second vulcanization mechanism 2 and the third vulcanization mechanism 3 have the same structure, and only the first vulcanization mechanism 1 is taken as an example here.

[0036] Specifically, the first vulcanization mechanism 1 includes an upper hot plate 16 and a lower hot plate 15, wherein the upper hot plate 16 is arranged at the output end of the longitudinal hydraulic cylinder, for driving the upper hot plate 16 to move longitudinally, and the upper hot plate 16 and the lower hot plate 15 are used to realize hot pressing of the rubber product, thereby realizing the vulcanization function, and after vulcanization, the rubber product on the lower hot plate 15 is transferred to the lower pressing plate 14, and the rubber product on the lower pressing plate 14 is pressed down by the longitudinally moving demolding tool 13.

[0037] Specifically, the upper pressing plate 12 is fixedly installed at the output end of the movable telescopic rod 11, and the movable telescopic rod 11 is used to realize the longitudinal movement of the upper pressing plate 12, so that the demolding tool 13 and the lower pressing plate 14 cooperate, the rubber product is squeezed off from the lower pressing plate 14 by the demolding tool 13, and the automatic discharging function of the rubber product is realized.

[0038] As the first embodiment of the present application, a plurality of groups of cylindrical rubber cores 1301 are uniformly fixed on the upper pressing plate 12, wherein the end of the cylindrical rubber core 1301 is arc-shaped, and a discharging groove 1302 is correspondingly formed on the lower pressing plate 14, wherein the position of the discharging groove 1302 cooperates with that of the cylindrical rubber core 1301, in order to realize the control of discharging the rubber product, a shielding assembly 1303 is installed inside the discharging groove 1302, wherein the shielding assembly 1303 includes a shielding body 1304, which is a leather bowl at this time, and a shielding protrusion 1305 is fixed to the shielding body 1304 in the direction facing the middle position of the discharging groove 1302, wherein the shielding body 1304 and the shielding protrusion 1305 are both soft, such as soft rubber.

[0039] That is, the vulcanized rubber is placed on the shielding protrusion 1305, the vulcanized rubber is limited by the shielding protrusion 1305, the upper stamping plate 12 drives the cylindrical rubber core 1301 to move longitudinally, the vulcanized rubber is pressed down, the shielding protrusion 1305 and the shielding body 1304 are pressed to the side, and the vulcanized rubber can be pressed and dropped from the discharge groove 1302. At this time, the shielding body 1304 is lifted with the cylindrical rubber core 1301, the position of the shielding body 1304 is moved, the rubber product cannot be protected in time, and the rubber product is at risk of being scratched.

[0040] As another embodiment of the present application, the original cylindrical rubber core 1301 is replaced by a conical rubber core 1306 in the present application. The conical rubber core 1306 includes a mounting plate 1307, which is fixed on the lower surface of the upper stamping plate 12 by bolts or welding and the like. A connecting plate 1308 is fixed to the side of the mounting plate 1307 away from the upper stamping plate 12, and an inclined plate 1309 is fixed to the connecting plate 1308. The inclined plate 1309 is in the shape of a bucket, and an ejection protrusion 1311 is fixed to the end of the inclined plate 1309. In this embodiment, the shielding body 1304 is made of hard material, and the shielding body 1304 is fixedly installed on the discharge groove 1302.

[0041] That is, in the process of use, the ejection protrusion 1311 directly contacts the upper surface of the vulcanized rubber. Since the size of the ejection protrusion 1311 is smaller than the size of the vulcanized rubber product, the ejection protrusion 1311 presses down the vulcanized rubber, so that the contact area between the ejection protrusion 1311 and the vulcanized rubber is small. Even if the ejection protrusion 1311 is not located at the center position of the vulcanized rubber, the position of the vulcanized rubber will be adjusted on the shielding protrusion 1305 during extrusion, until the position of the vulcanized rubber can be adjusted to the center position of the discharge groove 1302. Then, in the process of pressing down, the ejection protrusion 1311 can accurately press down the vulcanized rubber, so that the vulcanized rubber falls from the discharge groove 1302.

[0042] Further, the stepped limiting plates 1310 are uniformly fixed on the inclined plate 1309, so that the stepped limiting plates 1310 limit the extrusion of the vulcanized rubber from the discharge groove 1302. That is, when the stepped limiting plates 1310 are extruded on the shielding protrusion 1305, it can be determined that the vulcanized rubber is extruded and dropped from the discharge groove 1302, so as to avoid uneven stress caused by the position of the vulcanized rubber extruded on the shielding protrusion 1305 not being in the middle position.

[0043] When the pressure generated by the downward pressing of the tapered rubber core 1306 to the vulcanized rubber acts on the shielding protrusion 1305, if the vulcanized rubber is not in the center position of the discharge chute 1302, the pressure borne by the shielding protrusions 1305 on both sides will be unbalanced, causing the shielding assembly 1303 on one side to be pressed upward and move, causing the shielding protrusion 1305 to be pressed, thereby risking scratching the vulcanized rubber.

[0044] Therefore, a rotating support seat 1315 is fixed on the top of the shielding body 1304, wherein the rotating support seat 1315 is rotatably arranged on an internal rotating shaft 1318, wherein the internal rotating shaft 1318 is installed on the adjusting sliding rod 1314, and a torsional spring 1317 is fixed between the rotating support seat 1315 and the adjusting sliding rod 1314. That is, in use, if the force borne by the shielding protrusion 1305 is unbalanced, when the borne force is too large, the shielding body 1304 will rotate, that is, the shielding body 1304 will rotate on the internal rotating shaft 1318, at this time the torsional spring 1317 is subjected to a rotating force, which will alleviate the position of the vulcanized rubber during discharging, thereby further avoiding the scratching effect of the shielding protrusion 1305 on the vulcanized rubber.

[0045] Further, an adjusting sliding plate 1316 is fixed to the end of the adjusting sliding rod 1314 away from the internal rotating shaft 1318, wherein the adjusting sliding plate 1316 and the adjusting sleeve 1312 are slidingly connected, and an internal spring 1313 is fixed between the adjusting sliding plate 1316 and the adjusting sleeve 1312. That is, when the torsional spring 1317 bears a large force, due to the position of the vulcanized rubber not being in the middle position, at this time there will be a part of the transverse separation, moving the shielding body 1304, thereby controlling the adjusting sliding rod 1314 to slide inside the adjusting sleeve 1312, at this time the internal spring 1313 is subjected to a pressing force, further adjusting the position of the shielding protrusion 1305.

[0046] Wherein in the application, the middle groove 1319 is opened on the shielding body 1304, so that the shielding body 1304 is in the shape of "M", wherein the shielding protrusion 1305 comprises a first protrusion 1320, a second protrusion 1321 and a third protrusion 1322, so that when pressed, the position of the vulcanized rubber can be first adjusted by the first protrusion 1320, then the position of the vulcanized rubber is adjusted by the ejection protrusion 1311 when the vulcanized rubber is placed on the second protrusion 1321, and the position of the vulcanized rubber is adjusted by the third protrusion 1322 when the vulcanized rubber falls on the third protrusion 1322, so as to ensure the position stability of the vulcanized rubber in the discharge chute 1302, so in the application, the distance between the first protrusion 1320 and the center of the discharge chute 1302 is H1, the distance between the second protrusion 1321 and the center of the discharge chute 1302 is H2, and the distance between the third protrusion 1322 and the center of the discharge chute 1302 is H3, wherein H1>H2>H3, and the shielding body 1304 in the shape of "M" can make the vulcanized rubber move longitudinally when the position of the vulcanized rubber deviates and the angle deviates, so as to realize the discharge of the vulcanized rubber.

[0047] The connecting sleeve 1323 is fixed on the adjusting sliding rod 1314, the limiting support seat 1324 is fixed on the connecting sleeve 1323, and the limiting groove 1325 is opened in the limiting support seat 1324.

[0048] In use, the rubber product is placed on the lower hot plate 15, then the upper hot plate 16 is moved longitudinally, the upper hot plate 16 is pressed on the lower hot plate 15, the rubber product is heat-pressed to realize vulcanization, thereby generating vulcanized rubber, the generated vulcanized rubber is transferred to the lower pressing plate 14, the moving telescopic rod 11 is actuated to drive the upper pressing plate 12 to move longitudinally, and the demolding tool 13 is used for demolding the rubber product.

[0049] Specifically, the vulcanized rubber is located above the discharge chute 1302, that is, the vulcanized rubber is located on the shielding protrusion 1305, the vulcanized rubber is limited by the shielding protrusion 1305, the rubber core is moved longitudinally, that is, the rubber core is used for applying pressure to the vulcanized rubber downward, so that the edge position of the vulcanized rubber slides off the shielding protrusion 1305, thereby achieving automatic discharge of the vulcanized rubber from the discharge chute 1302.

[0050] That is, first, the ejection protrusion 1311 contacts the vulcanized rubber, and then downward pressure is applied using the ejection protrusion 1311, at which time the vulcanized rubber located on the shielding protrusion 1305 is adjusted in position so that the vulcanized rubber is located on the shielding protrusion 1305 and is placed more horizontally, and under the action of continuous downward pressure, the vulcanized rubber is pressed onto the second protrusion 1321, at which time the stepped limiting plate 1310 is located on the side of the first protrusion 1320 to preliminarily limit, so as to avoid the edge of the vulcanized rubber being folded, and then passes through the third protrusion 1322, and finally drops to achieve automatic dropping of the vulcanized rubber, in this process, by using the ejection protrusion 1311 to contact the vulcanized protrusion, the contact surface is small, which can ensure that the vulcanized rubber can reduce the risk of demolding, and at the same time, it can also reduce the force of the shielding assembly holding the core when the shielding assembly holding the core, thereby reducing the influence of the accumulated error;

[0051] At this time, if the hardness of the vulcanized rubber is large, the vulcanized rubber will push the shielding body 1304 to rotate, at which time the torsional spring 1317 is subjected to torsional force, enters the horizontal movement using the adjusting sliding rod 1314, so that the adjusting sliding plate 1316 moves inside the adjusting sleeve 1312, so that the internal spring 1313 is subjected to extrusion force, so as to adjust the position of the shielding protrusion 1305, facilitating the discharging of the vulcanized rubber;

[0052] If the hardness of the vulcanized rubber is small, only by the existence of the shielding protrusion 1305, the vulcanized rubber is pressed down from the shielding protrusion 1305, and because the size of the vulcanized rubber is larger than the size of the discharging groove 1302, after discharging, if the tapered rubber core 1306 is moved upward to return to the initial position, the vulcanized rubber adhered to the bottom of the tapered rubber core 1306 will be blocked by the shielding protrusion 1305, to realize automatic discharging.

[0053] The above is only a preferred embodiment of the present application, and does not limit the present application in any form, although the present application has been disclosed as above with a preferred embodiment, however, it is not intended to limit the present application, any person skilled in the art, without departing from the technical solution of the present application, can make some changes or modifications to the above disclosed technical content to make equivalent embodiments with equivalent changes, but as long as it does not deviate from the technical solution of the present application, any simple modification, equivalent change and modification of the above embodiments according to the technical essence of the present application, all still belong to the scope of the technical solution of the present application.
