Description

TECHNICAL FIELD

[0001] The utility model relates to rubber processing technical field, especially a mould opening heat preservation device and rubber processing equipment. BACKGROUND

[0002] In the process of producing and processing rubber products, the mould needs to be pressurized and vulcanized in a rubber injection machine (i.e. the rubber material is injected into a heated mould through a rubber injection machine for molding vulcanization) first, and then the mould is moved from the rubber injection machine to the mould opening and material taking station to take out the rubber products from the mould. Because the pressurized vulcanization step takes a certain amount of time, in order to improve production efficiency, some enterprises will adopt a production mode of one rubber injection machine matched with two sets of moulds. In order to facilitate understanding, the above two sets of moulds are named as first mould and second mould; when the first mould is pressurized and vulcanized, the second mould is opened and the material is taken out; when the second mould is pressurized and vulcanized, the first mould is opened and the material is taken out; and the above steps are alternately performed. The common mould includes first mould plate, second mould plate and third mould plate arranged from top to bottom, wherein the first mould plate is used as the runner plate of the rubber material, and the second mould plate and the third mould plate are combined to form the molding cavity of the rubber product; in the process of opening the mould and taking out the material, the first mould plate, the second mould plate and the third mould plate of the mould need to be separated from each other, so that the operator can take out the rubber product in the cavity area of the third mould plate.

[0003] In the prior art, the mould opening is manually opened; because the first mould plate is light in weight, the operator can manually turn and separate the first mould plate; and because the second mould plate is heavy, the operator needs to use a long steel bar or other tools to apply a force to the second mould plate in a direction away from the third mould plate to pry open and separate the second mould plate from the third mould plate, so that the operator can take out the rubber product in the cavity area, the above mould opening process is time-consuming and laborious, resulting in low production efficiency of the rubber product. At the same time, when one of the moulds is finished taking out the material and waits for the other mould to be pressurized and vulcanized, because the mould is in a normal temperature environment at this time, the normal temperature value is lower than the required mould temperature during pressurized vulcanization, resulting in a temperature loss during pressurized vulcanization of the mould and unstable quality of the rubber product.

[0044] The technical solutions in the utility model will be described clearly and completely in combination with the drawings in the utility model. Obviously, only some embodiments of the utility model are described, rather than all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by those skilled in the art without creative work belong to the protection scope of the utility model.

[0045] It should be noted that if the utility model embodiments involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement condition, etc. between the components in a certain posture (as shown in the drawings). If the certain posture changes, the directional indications also change accordingly.

[0046] In addition, it should be noted that the description of "first", "second" and the like in the utility model is only for the purpose of description, and cannot be understood as indicating or implying the relative importance of the indicated technical features or implicitly indicating the number of the indicated technical features. Therefore, the features limited by "first" and "second" can explicitly or implicitly include at least one feature. In addition, the technical solutions of each embodiment can be combined with each other, but it must be based on the realization of those skilled in the art. When the combination of technical solutions appears contradictory or unachievable, it should be considered that the combination of technical solutions does not exist and is not within the protection scope required by the utility model.

[0047] In the prior art, the mold opening adopts a manual opening mode. Since the weight of the first mold plate is relatively light, the operating personnel can manually flip and separate the first mold plate. Since the weight of the second mold plate is relatively heavy, the operating personnel needs to use a long steel rod or other tools to apply a force to the second mold plate in a direction away from the third mold plate to pry and separate the second mold plate from the third mold plate, so that the operating personnel can take out the rubber product in the mold cavity area. The above mold opening process is time-consuming and labor-consuming, thereby leading to low production efficiency of the rubber product. Meanwhile, when one mold finishes taking out the product and waits for another mold to perform pressurized vulcanization, since the mold is in a normal temperature environment at this time, the normal temperature value is lower than the required mold temperature during pressurized vulcanization, thereby leading to temperature loss during subsequent pressurized vulcanization of the mold and unstable quality of the rubber product.

[0048] To solve the above technical problems, the mold opening heat preservation device is provided.

[0049] Please refer to Figures 1-12 In an embodiment of the present application, the mold opening heat preservation device is used for opening and heat preservation of the mold, and the mold comprises a first mold plate, a second mold plate and a third mold plate which can be separated from each other.

[0050] Specifically, the mold opening heat preservation device comprises:

[0051] The rack 100 is used for carrying the mold (not shown in the drawing);

[0052] The upper hot plate assembly 400 is rotatably arranged on one side of the rack 100; the upper hot plate assembly 400 is used for heating and heat preservation of the mold, and the upper hot plate assembly 400 can support the separated first mold plate;

[0053] The clamping assembly 300 is rotatably arranged on the other side of the rack 100; the clamping assembly 300 is used for clamping and moving the second mold plate, so that the second mold plate is separated from the third mold plate;

[0054] The lower hot plate assembly 500 is arranged on the rack 100; the lower hot plate assembly 500 is used for heating and heat preservation of the mold, and the lower hot plate assembly 500 can support the third mold plate.

[0055] During operation, the mold is moved from the rubber injection machine to the rack 100 located in the material taking station for carrying, and the third mold plate is supported by the lower hot plate assembly 500; then the first mold plate is manually turned and separated by the operator, and the separated first mold plate is erected and supported on the upper hot plate assembly 400; then the second mold plate is clamped and rotated by the clamping assembly 300, so that the second mold plate is separated from the third mold plate, so that the operator can take out the rubber product in the cavity area of the third mold plate; since the separation process of the second mold plate and the third mold plate adopts the clamping assembly 300 to drive the operation, the mold opening efficiency is improved, and the production efficiency of the rubber product is improved. After the rubber product is taken out, the second mold plate and the first mold plate are reset in turn, then the upper hot plate assembly 400 is rotated to be connected with the mold, and then the mold is heated and preserved by the combined action of the upper hot plate assembly 400 and the lower hot plate assembly 500, so as to avoid the temperature loss of the subsequent mold during pressure vulcanization processing, so as to ensure the quality stability of the subsequent rubber product.

[0056] As a preferred scheme of the above embodiment, the mold opening heat preservation device further comprises an ejection assembly 200 arranged on the rack 100; the ejection assembly 200 is used for releasing the connection between the second mold plate and the third mold plate;

[0057] Specifically, the ejection assembly 200 is located in the lower region of the mold; the ejection assembly 200 comprises an ejector rod 210 and a first driving mechanism 220, the third mold plate is provided with a through hole for the ejection rod 210 to pass through; the first driving mechanism 220 is used to drive the ejection rod 210 to move upward, so that the ejection rod 210 passes through the through hole of the third mold plate and drives the second mold plate to move upward, so that the connection between the second mold plate and the third mold plate is released. Understandably, when the ejection rod 210 passes through the through hole of the third mold plate, it will abut against the second mold plate, and as the first driving mechanism 220 continues to drive the ejection rod 210 to move upward, the ejection rod 210 will drive the second mold plate to move upward away from the third mold plate, so as to achieve the purpose of releasing the connection between the second mold plate and the third mold plate; in this way, considering that the second mold plate and the third mold plate are commonly connected to each other by a plurality of guide columns, the guide columns are used to ensure that the second mold plate and the third mold plate can be positioned accurately when the mold is closed. However, since the second mold plate needs to be rotated and separated in the present application, in order to avoid the guide columns from causing obstruction, the second mold plate needs to be moved upward a certain distance away from the third mold plate by using the ejection assembly 200, so as to ensure that the guide columns will not simultaneously connect the second mold plate and the third mold plate, that is, release the connection between the second mold plate and the third mold plate. In the present embodiment, the ejection rod 210 and the first driving mechanism 220 are combined to form the ejection assembly 200, so that the ejection rod 210 can move upward and pass through the through hole of the third mold plate under the driving action of the first driving mechanism 220, and then lift the second mold plate, so as to ensure the smooth implementation of the technical solution of the present application, and the structure is simple and practical. Understandably, the lifting height of the second mold plate driven by the ejection rod 210 should be greater than the height of the guide column of the mold, so as to ensure that the guide column will not simultaneously connect the second mold plate and the third mold plate, thereby ensuring that the second mold plate is not hindered by the guide column during subsequent rotation.

[0058] Among them, there are many specific structures about the first driving mechanism 220, in the present embodiment, the first driving mechanism 220 comprises a first lifting driving device 230, the first lifting driving device 230 is fixedly connected with the rack 100; the driving end of the first lifting driving device 230 is connected with a driving plate 240, and the ejection rod 210 is installed on the side of the driving plate 240 away from the first lifting driving device 230; in this way, the first lifting driving device 230 is used as a power source to drive the driving plate 240 to move upward, thereby driving the ejection rod 210 installed on the driving plate 240 to move upward, so that the ejection rod 210 can smoothly lift the second mold plate. Among them, the lifting driving device can select a lifting oil cylinder, and the present application does not make specific limitation thereto.

[0059] Further, the ejection assembly 200 comprises at least two ejector rods 210, which are symmetrically arranged on opposite sides of the driving plate 240. In this way, the second mold plate is lifted by the simultaneous action of the at least two symmetrically arranged ejector rods 210, so that the force on both sides is balanced during the lifting of the second mold plate, which is beneficial to improve the stability of the second mold plate during the lifting movement. In this embodiment, four ejector rods 210 are arranged in a square on the driving plate 240.

[0060] As a preferred scheme of the above embodiment, the clamping assembly 300 comprises a turnover plate 310 and a second driving mechanism 320, the turnover plate 310 is used to be connected with the second mold plate, and the second driving mechanism 320 is used to drive the turnover plate 310 to rotate away from the third mold plate, so as to separate the second mold plate from the third mold plate, and thus expose the cavity region of the third mold plate. In this way, after the first mold plate is separated from the second mold plate, the second driving mechanism 320 first rotates the turnover plate 310 to be connected with the second mold plate, and then rotates the turnover plate 310 away from the third mold plate. Since the turnover plate 310 is connected with the second mold plate at this time, the second mold plate rotates away from the third mold plate, so as to separate the second mold plate from the third mold plate. The cavity region of the third mold plate is completely exposed, so as to facilitate the operator to take out the rubber product in the cavity region, and thus ensure the smooth implementation of the technical scheme, and the structure is simple and practical.

[0061] In this embodiment, the second driving mechanism 320 comprises a first telescopic driving device 330 and a first connecting rod 340, the first telescopic driving device 330 is fixedly connected with the rack 100, the first end of the first connecting rod 340 is movably connected with the turnover plate 310, the second end of the first connecting rod 340 is movably connected with the driving end of the first telescopic driving device 330, the middle part of the first connecting rod 340 is rotatably connected with the rack 100 through a first rotating shaft 341, and the side part of the turnover plate 310 is rotatably connected with the rack 100 through a second rotating shaft 311. Under the driving action of the first telescopic driving device 330, the first connecting rod 340 rotates around the first rotating shaft 341, so as to drive the turnover plate 310 to rotate around the second rotating shaft 311 to the first position or the second position. Figure 5 When the turnover plate 310 rotates to the first position (as shown in FIG. 6), the second mold plate is close to the third mold plate; when the turnover plate is located at the second position (as shown in FIG. 7), the second mold plate is separated from the third mold plate. Figure 6As shown in FIG. 6, the second template is away from the third template, so that the cavity region of the third template is exposed. In this way, the first telescopic driving device 330 is used as a power source to drive the second end of the first connecting rod 340 to displace, so that the first connecting rod 340 rotates around the first rotation axis 341 to move, thereby causing the first end of the first connecting rod 340 to displace, and further causing the turnover plate 310 to rotate around the second rotation axis 311. When the turnover plate 310 rotates to the first position, the second template is close to the third template at this time, and the cavity region of the third template is not exposed. Then, the turnover plate 310 is connected with the second template, so that the turnover plate 310 can subsequently drive the second template to rotate. When the turnover plate 310 rotates to the second position, the second template is away from the third template at this time, and the cavity region of the third template is exposed. Thus, the operator can conveniently take out the rubber product in the cavity region. In this embodiment, the first telescopic driving device 330 can be a telescopic oil cylinder, which is not limited in the present application.

[0062] In the embodiment, the rotation amplitude a of the turnover plate 310 around the second rotation axis 311 is 110°-130°. In this way, by limiting the rotation amplitude a of the turnover plate 310, when the turnover plate 310 is in the second position, the second template is located outside the region directly above the third template (a>90°), so that the cavity region of the third template is completely exposed.

[0063] Further, the first connecting rod 340 is provided with a first linear sliding mechanism 350 at the connection with the turnover plate 310. In this way, referring to FIG. 5, the first linear sliding mechanism 350 is arranged on the first connecting rod 340, and the first linear sliding mechanism 350 is arranged on the turnover plate 310. Figures 5-6 When the turnover plate 310 rotates around the second rotation axis 311, the connection between the first end of the first connecting rod 340 and the turnover plate 310 also displaces. In order to ensure that the first connecting rod 340 does not hinder the rotation of the turnover plate 310 around the second rotation axis 311, a linear sliding structure is arranged at the connection between the first connecting rod 340 and the turnover plate 310 to adaptively adjust the position of the connection between the first connecting rod 340 and the turnover plate 310.

[0064] Specifically, the first linear sliding mechanism 350 includes a first sliding block 351 and a first sliding rail 352. The first sliding block 351 is rotationally connected with the first end of the first connecting rod 340, and the first sliding rail 352 is fixedly connected with the turnover plate 310. The first sliding block 351 is slidably connected with the first sliding rail 352. In this way, by the sliding connection between the first sliding block 351 and the first sliding rail 352, when the turnover plate 310 rotates around the second rotation axis 311, the connection between the first end of the first connecting rod 340 and the turnover plate 310 can displace along the second sliding rail 452, so as to ensure that the technical scheme of the present application can be effectively implemented.

[0065] Further, the first sliding rail 352 is provided with first limiting blocks 353 at opposite ends thereof, and the first limiting blocks 353 are used to abut against the first sliding block 351. In this way, the first limiting blocks 353 can limit the first sliding block 351 from moving too far away from the first sliding rail 352, and the sliding limit of the first sliding block 351 can only be abutted against the first limiting blocks 353 at both sides. Therefore, the rotation range of the turnover plate 310 around the second rotation shaft 311 can be adjusted by adjusting the positions of the first limiting blocks 353 on the first sliding rail 352.

[0066] Further, the second driving mechanism 320 comprises a first limiting frame 360, and the first limiting frame 360 is provided with a first contact sensor 361, which is electrically connected with the first telescopic driving device 330. When the turnover plate 310 rotates to the second position, the turnover plate 310 abuts against the first limiting frame 360, and the turnover plate 310 contacts the first contact sensor 361. In this way, in order to ensure that the turnover plate 310 can rotate to the second position accurately, the first limiting frame 360 is arranged at the second position of the turnover plate 310. When the turnover plate 310 abuts against the first limiting frame 360, it means that the turnover plate 310 has rotated to the second position, and the abutting of the first limiting frame 360 can limit the continuous rotation of the turnover plate 310. Meanwhile, the first contact sensor 361 is arranged on the first limiting frame 360, and when the turnover plate 310 contacts the first contact sensor 361, the first contact sensor 361 sends an electric signal to the first telescopic driving device 330 to stop the operation of the first telescopic driving device 330, so as to stop the continuous rotation of the turnover plate 310.

[0067] The turnover plate 310 is provided with a clamping mechanism 370 and a position adjusting mechanism 380. The clamping mechanism 370 is used for clamping operation on the handle part of the second template, so that the turnover plate 310 and the second template are connected with each other. The driving end of the position adjusting mechanism 380 is connected with the clamping mechanism 370. The position adjusting mechanism 380 is used for adjusting the position of the clamping mechanism 370. In this way, on the one hand, the position adjusting mechanism 380 drives the clamping mechanism 370 to move to the position of the handle part of the second template, so that the clamping mechanism 370 can smoothly clamp the handle part. On the other hand, considering that the rotation axis of the second template does not coincide with the rotation axis of the turnover plate 310, therefore, in the process of rotating the second template driven by the turnover plate 310, because the rotation radius of the second template is different from the rotation radius of the turnover plate 310, the connection between the turnover plate 310 and the second template is displaced with rotation. Therefore, the position adjusting mechanism 380 is used to adjust the position of the clamping mechanism 370 in real time, so as to ensure that the second template can rotate with the turnover plate 310 on the basis of keeping the connection between the turnover plate 310 and the second template.

[0068] Specifically, the clamping mechanism 370 includes a clamping driving device 371 and two clamping blocks 372 arranged opposite to each other. The clamping driving device 371 is used for driving the two clamping blocks 372 to move close to each other, so that the two clamping blocks 372 are combined with each other to clamp the handle part of the second template. In this way, the clamping driving device 371 is used as a power source to drive the two clamping blocks 372 to move close to each other, so as to clamp and fix the handle part, thereby realizing the fixed connection between the turnover plate 310 and the second template. The structure is simple and practical. In this embodiment, the clamping driving device 371 can be a clamping cylinder, and the present application does not make specific limitation thereto.

[0069] Specifically, the position adjusting mechanism 380 comprises a displacement driving device 381, a third sliding block 382 and a third sliding rail 383; the displacement driving device 381 is configured to drive the third sliding block 382 to slide along the third sliding rail 383; the third sliding block 382 is fixedly connected with the clamping mechanism 370; and the third sliding rail 383 is fixedly connected with the turnover plate 310. In this way, on the one hand, during the clamping operation of the clamping mechanism 370 on the handle part, the displacement driving device 381 is taken as a power source to drive the third sliding block 382 to displace along the third sliding rail 383, so as to adjust the position of the clamping mechanism 370 installed on the third sliding block 382, so as to move the clamping mechanism 370 to the position of the handle part, so that the clamping mechanism 370 can clamp the handle part; on the other hand, during the rotation of the second mold plate driven by the turnover plate 310, the displacement driving device 381 is set to be in a non-working state, at this time, the third sliding block 382 and the third sliding rail 383 are in an automatic sliding state, so that the position of the clamping mechanism 370 can be adaptively adjusted along the third sliding rail 383, so as to achieve the purpose of real-time adjustment of the position of the clamping mechanism 370.

[0070] In the embodiment, the displacement driving device 381 can be a telescopic cylinder, which is not limited in the application. The telescopic cylinder is controlled by a three-position five-way spool valve, when the displacement driving device 381 needs to be set to a non-working state, the electromagnetic valve of the telescopic cylinder is switched to the middle position to vent, so that the third sliding block 382 is in a floating state, so that it can be adaptively adjusted along the third sliding rail 383, to ensure the smooth implementation of the embodiment.

[0071] As a preferred scheme of the above embodiment, the upper heating plate assembly 400 comprises an upper heating plate 410 and a third driving mechanism 420, the third driving mechanism 420 is configured to drive the upper heating plate 410 to rotate to be mutually attached to the top side of the mold, so that the upper heating plate 410 heats and warms the mold; in this way, the upper heating plate 410 is moved to be mutually attached to the top side of the mold by the third driving mechanism 420, so that the upper heating plate 410 can heat and warm the mold, wherein the inside of the upper heating plate 410 is provided with a heating device, such as a heating wire, etc., the upper heating plate 410 is warmed by the heating device, and then the mold mutually attached to the upper heating plate 410 is also warmed, to ensure the smooth implementation of the technical scheme of the application, and the structure is simple and practical.

[0072] The third drive mechanism 420 can have various specific structures. In this embodiment, the third drive mechanism 420 includes a second telescopic drive device 430 and a second connecting rod 440. The second telescopic drive device 430 is fixedly connected to the frame 100. The first end of the second connecting rod 440 is movably connected to the upper heating plate 410, and the second end of the second connecting rod 440 is movably connected to the drive end of the second telescopic drive device 430. The middle part of the second connecting rod 440 is rotatably connected to the frame 100 via a third rotating shaft 441. The side of the upper heating plate 410 is rotatably connected to the frame 100 via a fourth rotating shaft 411. Under the driving action of the second telescopic drive device 430, the second connecting rod 440 rotates around the third rotating shaft 441, thereby driving the upper heating plate 410 to rotate around the fourth rotating shaft 411 to a third or fourth position. When the upper heating plate 410 rotates to the third position (as shown in the attached diagram), Figure 9 As shown), the upper heating plate 410 is in contact with the top side of the mold; when the upper heating plate 410 rotates to the fourth position (as shown in the attached figure), Figure 10 As shown, the upper heating plate 410 is released from contact with the top side of the mold. With this configuration, the second telescopic drive device 430 acts as a power source, driving the second end of the second connecting rod 440 to rotate around the third rotating axis 441. This causes the first end of the second connecting rod 440 to move, which in turn causes the upper heating plate 410 to rotate around the fourth rotating axis 411. When the upper heating plate 410 rotates to the third position, it contacts the top side of the mold, allowing it to heat the top side of the mold and ensure the effective implementation of the technical solution of this application. The telescopic drive device can be a telescopic hydraulic cylinder; this application does not impose specific limitations on it.

[0073] In this embodiment, the rotation range β of the upper heating plate 410 around the fourth rotation axis 411 is 120°~150°. This setting, by limiting the rotation range β of the upper heating plate 410, ensures that when the upper heating plate 410 is in the third position, it can smoothly fit against the mold. Furthermore, when the upper heating plate 410 is in the fourth position, the angle between the upper heating plate 410 and the mold is obtuse, allowing the upper heating plate to effectively support the separated first template, preventing the first template from rotating and falling back to fit against the second template under its own gravity.

[0074] Furthermore, a second linear sliding mechanism 450 is provided at the connection between the second connecting rod 440 and the upper heating plate 410, as shown in the attached diagram. Figures 9-10When the upper hot plate 410 rotates around the fourth rotation axis 411, the connection between the first end of the second connecting rod 440 and the upper hot plate 410 also displaces; in order to ensure that the upper hot plate 410 can smoothly rotate around the fourth rotation axis 411, and the connecting rod does not hinder it, a linear sliding mechanism needs to be arranged at the connection between the second connecting rod 440 and the upper hot plate 410, to realize adaptive adjustment of the position of the connection between the second connecting rod 440 and the upper hot plate 410.

[0075] Specifically, the second linear sliding mechanism 450 includes a second sliding block 451 and a second sliding rail 452, the second sliding block 451 is rotationally connected with the first end of the second connecting rod 440, and the second sliding rail 452 is fixedly connected with the upper hot plate 410; the second sliding block 451 is slidingly connected with the second sliding rail 452; in this way, through the sliding connection between the second sliding block 451 and the second sliding rail 452, when the upper hot plate 410 rotates around the fourth rotation axis 411, the connection between the first end of the second connecting rod 440 and the upper hot plate 410 can displace along the rail of the second sliding rail 452, to ensure that the technical scheme of the application can be effectively implemented.

[0076] Further, the rail of the second sliding rail 452 is provided with a second limiting block 453 at opposite ends, and the second limiting block 453 is used for abutting against the second sliding block 451. In this way, through the limiting action of the second limiting block 453, it is ensured that the second sliding block 451 does not displace excessively and is separated from the second sliding rail 452, and since the sliding limit position of the second sliding block 451 can only slide to abut against the second limiting block 453, the rotation range of the upper hot plate 410 around the fourth rotation axis 411 can also be adjusted by adjusting the position of the second limiting block 453 on the second sliding rail 452.

[0077] Further, the third driving mechanism 420 comprises a second limiting frame 460, the second limiting frame 460 is provided with a second contact sensor 461, the second contact sensor 461 is electrically connected with the second telescopic driving device 430; when the upper hot plate 410 rotates to the fourth position, the upper hot plate 410 and the second limiting frame 460 abut each other, and the upper hot plate 410 and the second contact sensor 461 contact each other. By such arrangement, in order to ensure that the upper hot plate 410 can be accurately rotated to the second position, the second limiting frame 460 is arranged at the second position of the embodiment, when the upper hot plate 410 rotates to abut the second limiting frame 460, it means that the upper hot plate 410 has been rotated to the second position, at this time, the abutting action of the second limiting frame 460 limits the continuous rotation of the upper hot plate 410. At the same time, the second contact sensor 461 is arranged at the second limiting frame 460, when the upper hot plate 410 and the second contact sensor 461 contact each other, the second contact sensor 461 sends an electric signal to the second telescopic driving device 430 to stop the operation of the second telescopic driving device 430, and further stop the continuous rotation of the upper hot plate 410.

[0078] Further, the middle part of the second connecting rod 440 is provided with a plurality of hollow holes 442; by such arrangement, the hollow holes 442 are arranged to reduce the overall weight of the second connecting rod 440, so that the second telescopic driving device 430 can drive the second connecting rod 440 to rotate with smaller driving power, which helps to save energy and labor.

[0079] As a preferred scheme of the above embodiment, the lower hot plate assembly 500 is located in the lower area of the mold; the lower hot plate assembly 500 comprises a lower hot plate 510 and a fourth driving mechanism 520, the fourth driving mechanism 520 is used to drive the lower hot plate 510 to move to abut the bottom side of the mold, so that the lower hot plate 510 heats and warms the mold; by such arrangement, the fourth driving mechanism 520 moves the lower hot plate 510 to abut the bottom side of the mold, so that the lower hot plate 510 can heat and warm the mold, wherein the inside of the lower hot plate 510 is provided with a heating device, such as a heating wire, etc., the heating device is used to warm the lower hot plate 510, and then the mold abutting the lower hot plate 510 is also warmed, so as to ensure the smooth implementation of the technical scheme of the application, and the structure is simple and practical.

[0080] The fourth driving mechanism 520 has many specific structures, and in the embodiment, the fourth driving mechanism 520 comprises a second lifting driving device 530 fixedly connected with the rack 100; the driving end of the second lifting driving device 530 is fixedly connected with the lower heat plate 510; in this way, the second lifting driving device 530 is used as a power source to drive the lower heat plate 510 to move upward to be in close contact with the bottom side of the mold, so that the lower heat plate 510 can heat and warm the bottom side of the mold, to ensure that the technical scheme can be effectively implemented. The lifting driving device can be a lifting oil cylinder, and the application does not make specific limitations.

[0081] Further, the fourth driving mechanism 520 comprises at least two second lifting driving devices 530, and the at least two lifting driving devices are symmetrically arranged on the opposite sides of the bottom of the lower heat plate 510. In this way, when the lower heat plate 510 moves up and down, the left and right forces are balanced, which is beneficial to improve the stability of the lower heat plate 510 when moving up and down. In the embodiment, the number of lifting driving devices is two.

[0082] It should be noted that, with reference to the accompanying drawings Figure 12 Since the lower heat plate assembly 500 and the ejection assembly 200 are also arranged at the lower position of the mold, to avoid the mutual interference of the movement of the lower heat plate 510 and the ejector rod 210, the lower heat plate 510 needs to be provided with a vertically penetrating avoidance hole 511 for the ejector rod 210 to pass through, so that the lower heat plate 510 and the ejector rod 210 can move relative to each other through the avoidance hole 511, to ensure that the movement of the lower heat plate 510 and the ejector rod 210 does not interfere with each other. At the same time, the first lifting driving device 230 and the second lifting driving device 530 are also arranged in a staggered distribution structure.

[0083] In other embodiments, the inner side wall of the avoidance hole 511 and the outer side wall of the ejector rod 210 are arranged in close contact with each other, so that the avoidance hole 511 and the ejector rod 210 have a mutual limiting and guiding effect; in this way, on the one hand, the movement freedom of the ejector rod 210 is limited by the lower heat plate 510, to ensure that the ejector rod 210 can only move up and down in the vertical direction under the driving action of the first lifting driving device 230; on the other hand, the movement freedom of the lower heat plate 510 is limited by the ejector rod 210, to ensure that the lower heat plate 510 can only move up and down in the vertical direction under the driving action of the second lifting driving device 530.
