Description

Technical Field

[0001] The invention relates to the technical field of rubber processing, and in particular to a mold opening and heat preservation device and rubber processing equipment. Background Art

[0002] In the process of producing and processing rubber products, the rubber processing equipment needs to first perform pressure vulcanization processing on the mold in the rubber injection machine (that is, inject the rubber into the heated mold through the rubber injection machine for molding and vulcanization), and then move the mold from the rubber injection machine to the mold opening and material taking station to take the rubber product out of the mold. Since the pressure vulcanization step takes a certain amount of time, in order to improve production efficiency, some companies will use a rubber injection machine with two sets of molds. For ease of understanding, the above two sets of molds are named the first mold and the second mold respectively; when the first mold is under pressure vulcanization, the second mold is under mold opening and material taking operation; when the second mold is under pressure vulcanization, the first mold is under mold opening and material taking operation; and so on. A common mold includes a first template, a second template and a third template arranged in sequence from top to bottom, wherein the first template is used as a runner plate for the rubber material, and the second template and the third template are used to combine to form a molding cavity for the rubber product; during the mold opening and material removal process, the first template, the second template and the third template of the mold need to be separated from each other so that the operator can take out the rubber product located in the cavity area of ​​the third template.

[0003] In the prior art, the mold is opened manually; since the weight of the first template is relatively light, the operator can just flip and separate the first template manually; and the weight of the second template is relatively heavy, so the operator needs to use tools such as long steel bars to apply a force to the second template away from the third template to pry the second template apart from the third template, so that the operator can take out the rubber products in the mold cavity area. The above mold opening process is time-consuming and labor-intensive, resulting in low production efficiency of rubber products. At the same time, when one mold has finished taking the material and is waiting for another mold to be pressurized and vulcanized, since one mold is at room temperature at this time, its room temperature value is lower than the mold temperature required for pressurized vulcanization, which causes the subsequent one mold to lose temperature during pressurized vulcanization processing, resulting in unstable quality of its rubber products.

[0004] It should be noted that the above contents are only used to assist in understanding the technical solution of the present invention, and do not constitute an admission that the above contents are prior art. Summary of the invention

DETAILED DESCRIPTION

[0020] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solution in the present invention. Obviously, what is described is only a part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0021] It should be noted that if the embodiments of the present invention 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 status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0022] In addition, it should be noted that the descriptions of "first", "second", etc. in the present invention are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0023] In the prior art, the mold opening is done manually. Since the weight of the first template is relatively light, the operator can just flip and separate the first template manually. However, the weight of the second template is relatively heavy, so the operator needs to use tools such as long steel bars to apply a force to the second template away from the third template to pry the second template apart from the third template, so that the operator can take out the rubber products in the mold cavity area. The above mold opening process is time-consuming and labor-intensive, resulting in low production efficiency of rubber products. At the same time, when one mold has finished taking the material and is waiting for another mold to be pressurized and vulcanized, since one mold is at room temperature at this time, its room temperature value is lower than the mold temperature required for pressurized vulcanization, which causes the subsequent one mold to lose temperature during pressurized vulcanization, resulting in unstable quality of its rubber products.

[0024] In order to solve the above technical problems, the present invention proposes a mold opening and heat preservation device.

[0025] See also Figure 1-12 In one embodiment of the present invention, the mold opening and heat preservation device is used to open and heat the mold, and the mold includes a first template, a second template and a third template that can be separated from each other; Specifically, the mold opening and heat preservation device comprises: A frame 100, the frame 100 is used to carry a mold (not shown in the drawings); The upper hot plate assembly 400 is rotatably disposed on one side of the frame 100; the upper hot plate assembly 400 is used to heat and keep the mold warm, and the upper hot plate assembly 400 can support the first template after separation; The clamping assembly 300 is rotatably disposed on the other side of the frame 100; the clamping assembly 300 is used to clamp and move the second template so that the second template is separated from the third template; The lower hot plate assembly 500 is disposed on the frame 100 ; the lower hot plate assembly 500 is used to heat and keep the mold warm, and the lower hot plate assembly 500 can support the third template.

[0026] During operation, the mold is moved from the rubber injection machine to the frame 100 located at the material taking station for bearing, and the lower hot plate assembly 500 is used to support the third template; then the operator manually flips and separates the first template, and sets up and supports the separated first template on the upper hot plate assembly 400; then the clamping assembly 300 is used to clamp the second template and rotate it, so that the second template and the third template are separated from each other, so that the operator can take out the rubber product located in the mold cavity area of ​​the third template; because the above-mentioned separation process of the second template and the third template uses the clamping assembly 300 to drive the operation, the mold opening efficiency is improved, and then the production efficiency of rubber products is improved. When the rubber product is taken, the second template and the first template are reset successively, and then the upper hot plate assembly 400 is rotated to be connected with the mold, and then the mold is heated and insulated by the combined action of the upper hot plate assembly 400 and the lower hot plate assembly 500, so as to avoid the subsequent mold from losing temperature during the pressurized vulcanization process, so as to ensure the quality stability of the subsequent rubber products.

[0027] As a preferred solution of the above embodiment, the mold opening and heat preservation device further includes an ejector assembly 200, which is arranged on the frame 100; the ejector assembly 200 is used to release the connection between the second template and the third template; Specifically, the ejector assembly 200 is located in the lower area of ​​the mold; the ejector assembly 200 includes an ejector rod 210 and a first driving mechanism 220, and the third template is provided with a through hole for the ejector rod 210 to pass through; the first driving mechanism 220 is used to drive the ejector rod 210 to move upward, so that the ejector rod 210 passes through the through hole of the third template and drives the second template to move upward, so that the connection between the second template and the third template is released. It can be understood that after the ejector rod 210 passes through the through hole of the third template, it will abut against the second template. As the first driving mechanism 220 continues to drive the ejector rod 210 to move upward, the ejector rod 210 will drive the second template to move upward in a direction away from the third template, so as to achieve the purpose of releasing the connection between the second template and the third template; such a configuration is made, considering that the common second template and the third template are connected to each other through a plurality of guide pillars, and the guiding property of the guide pillars is used to ensure that the second template and the third template can be accurately positioned when the mold is closed. However, since the second template needs to be rotated and separated in this application, in order to avoid the obstruction caused by its guide column, it is necessary to first use the ejection assembly 200 to move the second template upward a certain distance away from the third template to ensure that the guide column does not simultaneously connect the second template and the third template, that is, to release the connection between the second template and the third template. In this embodiment, by combining the ejector 210 with the first drive mechanism 220 to form the ejection assembly 200, the ejector 210 can move upward and pass through the through hole of the third template under the driving action of the first drive mechanism 220 to lift the second template, so as to ensure the smooth implementation of the technical solution of this application, and the structure is simple and practical. It can be understood that the lifting height of the second template driven by the ejector 210 should be greater than the height of the guide column of the mold, so as to ensure that the guide column does not simultaneously connect the second template and the third template, thereby ensuring that the subsequent rotation of the second template is not hindered by the guide column.

[0028] There are many specific structures of the first driving mechanism 220. In this embodiment, the first driving mechanism 220 includes a first lifting driving device 230, which is fixedly connected to the frame 100; the driving end of the first lifting driving device 230 is connected to the driving plate 240, and the push 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 push rod 210 installed on the driving plate 240 to move upward, so that the push rod 210 can smoothly lift the second template. The above-mentioned lifting driving device can select a lifting cylinder, and this application does not impose specific restrictions on it.

[0029] Furthermore, the ejector assembly 200 includes at least two ejector rods 210, which are symmetrically arranged on opposite sides of the driving plate 240. In this way, by arranging at least two symmetrically arranged ejector rods 210 to simultaneously lift the second template, the forces on both sides of the second template are balanced during the lifting process, which is conducive to improving the stability of the second template during the lifting movement. In this embodiment, four ejector rods 210 are arranged, and the four ejector rods 210 are arranged in a square shape on the driving plate 240.

[0030] As a preferred embodiment of the above embodiment, the clamping assembly 300 includes a flip plate 310 and a second driving mechanism 320. The flip plate 310 is used to be interconnected with the second template, and the second driving mechanism 320 is used to drive the flip plate 310 to rotate in a direction away from the third template, so that the second template is separated from the third template, thereby exposing the mold cavity area of ​​the third template; in this way, after the first template is separated from the second template, the second driving mechanism 320 first rotates the flip plate 310 to be interconnected with the second template; then the flip plate 310 is rotated in a direction away from the third template. Since the flip plate 310 and the second template are in a state of interconnection at this time, the second template is rotated in a direction away from the third template, thereby achieving the purpose of separating the second template from the third template; the mold cavity area of ​​the third template is completely exposed, thereby facilitating the operator to perform material removal operations on the rubber products in the mold cavity area, thereby ensuring the smooth implementation of the technical solution of the present application, and the structure is simple and practical.

[0031] Among them, there are many kinds of specific structures about the second driving mechanism 320. In the present embodiment, the second driving mechanism 320 includes a first telescopic driving device 330 and a first connecting rod 340. The first telescopic driving device 330 is fixedly connected to the frame 100; the first end of the first connecting rod 340 is movably connected to the flip plate 310, and the second end of the first connecting rod 340 is movably connected to the driving end of the first telescopic driving device 330; the middle part of the first connecting rod 340 is rotatably connected to the frame 100 through the first rotating shaft 341; the side part of the flip plate 310 is rotatably connected to the frame 100 through the 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 to drive the flip plate 310 to rotate around the second rotating shaft 311 to the first position or the second position; when the flip plate 310 rotates to the first position (as shown in the attached Figure 5 As shown in the figure, the second template is close to the third template; when the flip plate is in the second position (as shown in the figure), ... Figure 6As shown), the second template is away from the third template, so that the mold cavity area of ​​the third template is exposed. In this way, the first telescopic drive 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, thereby causing the first end of the first connecting rod 340 to displace, and then the flip plate 310 rotates around the second rotation axis 311; when the flip plate 310 rotates to the first position, the second template is close to the third template, and the mold cavity area of ​​the third template is not exposed; then the flip plate 310 is connected to the second template, so that the flip plate 310 can subsequently drive the second template to rotate; when the flip plate 310 rotates to the second position, the second template is away from the third template, and the mold cavity area of ​​the third template is exposed; thereby facilitating the operator to take the rubber product in the mold cavity area. In this embodiment, the first telescopic drive device 330 can be selected as a telescopic oil cylinder, and this application does not impose specific restrictions on it.

[0032] In the embodiment, the rotation amplitude α of the flip plate 310 around the second rotation axis 311 is 110° to 130°. In this way, by limiting the rotation amplitude α of the flip plate 310, when the flip plate 310 is in the second position, the second template is located outside the area directly above the third template (α is greater than 90°), thereby ensuring that the mold cavity area of ​​the third template is completely exposed.

[0033] Furthermore, a first linear sliding mechanism 350 is provided at the connection between the first link member 340 and the flip plate 310. Figure 5-6 When the flip plate 310 rotates around the second rotation axis 311, the connection between the first end of the first link 340 and the flip plate 310 also moves accordingly; to ensure that the first link 340 does not cause any obstruction to the flip plate 310 when it can smoothly rotate around the second rotation axis 311, a linear sliding structure is required to be provided at the connection between the first link 340 and the flip plate 310 to achieve adaptive adjustment of the connection position between the first link 340 and the flip plate 310.

[0034] Specifically, the first linear sliding mechanism 350 includes a first slider 351 and a first slide rail 352. The first slider 351 is rotatably connected to the first end of the first connecting rod 340, and the first slide rail 352 is fixedly connected to the flip plate 310; the first slider 351 is slidably connected to the first slide rail 352; in this way, through the sliding connection between the first slider 351 and the first slide rail 352, when the flip plate 310 rotates around the second rotation axis 311, the connection between the first end of the connecting rod and the flip plate 310 can be displaced along the track direction of the second slide rail 452 to ensure that the technical solution of the present application can be effectively implemented.

[0035] Furthermore, first limit blocks 353 are respectively provided at opposite ends of the first slide rail 352, and the first limit blocks 353 are used to abut against the first slider 351. In this way, the first limit blocks 353 can limit the displacement of the first slider 351 and prevent it from being separated from the first slide rail 352. At the same time, since the sliding limit position of the first slider 351 can only slide to abut against the first limit blocks 353 on both sides, the rotation range of the flip plate 310 around the second rotation axis 311 can be adjusted by adjusting the position of the first limit blocks 353 on the first slide rail 352.

[0036] Furthermore, the second driving mechanism 320 includes a first limiting frame 360, and the first limiting frame 360 ​​is provided with a first contact sensor 361, and the first contact sensor 361 is electrically connected to the first telescopic driving device 330; when the flip plate 310 rotates to the second position, the flip plate 310 and the first limiting frame 360 ​​abut against each other, and the flip plate 310 and the first contact sensor 361 contact each other. In this way, in order to ensure that the flip plate 310 can accurately rotate to the second position, the first limiting frame 360 ​​is provided at the second position of the present embodiment. When the flip plate 310 rotates to abut against the first limiting frame 360, it means that the flip plate 310 has rotated to the second position. At this time, the abutment of the first limiting frame 360 ​​limits the continued rotation of the flip plate 310. At the same time, a first contact sensor 361 is set on the first limit frame 360. When the flip plate 310 and the first contact sensor 361 contact each other, the first contact sensor 361 sends an electrical signal to the first telescopic driving device 330 to stop the operation of the first telescopic driving device 330, thereby stopping the continued rotation of the flip plate 310.

[0037] The above-mentioned flip plate 310 is provided with a clamping mechanism 370 and a position adjustment mechanism 380. The clamping mechanism 370 is used to clamp the handle of the second template so that the flip plate 310 and the second template are connected to each other; the driving end of the position adjustment mechanism 380 is connected to the clamping mechanism 370, and the position adjustment mechanism 380 is used to adjust the position of the clamping mechanism 370; in this way, on the one hand, the position adjustment mechanism 380 is used to drive the clamping mechanism 370 to move to the position of the handle of the second template, so that the clamping mechanism 370 can smoothly clamp the handle. On the other hand, considering that the rotation axis of the second template does not coincide with the rotation axis of the flip plate 310, during the process of the flip plate 310 driving the second template to rotate, due to the difference in the rotation radius of the second template and the rotation radius of the flip plate 310, the connection between the flip plate 310 and the second template is displaced as the flip plate 310 rotates; therefore, it is necessary to use the position adjustment mechanism 380 to adjust the position of the clamping mechanism 370 in real time to ensure that the flip plate 310 and the second template can rotate as the flip plate 310 rotates while maintaining the connection state.

[0038] Specifically, the clamping mechanism 370 includes a clamping drive device 371 and two clamping blocks 372 arranged opposite to each other. The clamping drive device 371 is used to drive the two clamping blocks 372 to move closer to each other so that the two clamping blocks 372 are combined with each other to clamp the handle of the second template. In this way, the clamping drive device 371 is used as a power source to drive the two clamping blocks 372 to move closer to each other so as to clamp and fix the handle, thereby realizing a fixed connection between the flip plate 310 and the second template. The structure is simple and practical. In this embodiment, the clamping drive device 371 can select a clamping cylinder, and this application does not make any specific restrictions on it.

[0039] Specifically, the position adjustment mechanism 380 includes a displacement drive device 381, a third slider 382 and a third slide rail 383; the displacement drive device 381 is used to drive the third slider 382 to slide along the third slide rail 383; wherein the third slider 382 is fixedly connected to the clamping mechanism 370; and the third slide rail 383 is fixedly connected to the flip plate 310. With such arrangement, on the one hand, in the process of the clamping mechanism 370 clamping the handle part, the displacement driving device 381 is used as a power source to drive the third slider 382 to displace along the track direction of the third slide rail 383, thereby adjusting the position of the clamping mechanism 370 installed on the third slider 382, ​​so as to achieve the purpose of moving 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, in the process of the flip plate 310 driving the second template to rotate, the displacement driving device 381 is set to a non-working state, at which time the third slider 382 and the third slide rail 383 are in an automatic sliding state, so that the position of the clamping mechanism 370 can be adaptively adjusted along the track direction of the third slide rail 383, thereby achieving the purpose of real-time adjustment of the position of the clamping mechanism 370.

[0040] In this embodiment, the displacement driving device 381 can be a telescopic cylinder, which is not specifically limited in this application. The telescopic cylinder is controlled by a three-position five-way center-drain solenoid valve. When the displacement driving device 381 needs to be set to a non-working state, the solenoid valve of the telescopic cylinder is switched to a center-drain state, so that the third slider 382 is in a floating state, so that it can be adaptively adjusted along the third slide rail 383 to ensure the smooth implementation of this embodiment.

[0041] As a preferred solution of the above embodiment, the upper hot plate assembly 400 includes an upper hot plate 410 and a third driving mechanism 420, wherein the third driving mechanism 420 is used to drive the upper hot plate 410 to rotate until it is in contact with the top side of the mold, so that the upper hot plate 410 heats and heats the mold; in this way, the upper hot plate 410 is moved to be in contact with the top side of the mold by the third driving mechanism 420, so that the upper hot plate 410 can heat and heat the mold, wherein a heating device, such as a heating wire, is provided inside the upper hot plate 410, and the upper hot plate 410 is heated by the heating device, and then the mold in contact with the upper hot plate 410 is also heated accordingly, so as to ensure the smooth implementation of the technical solution of the present application, and the structure is simple and practical.

[0042] Among them, there are many specific structures of the above-mentioned third driving mechanism 420. In the present embodiment, the third driving mechanism 420 includes a second telescopic driving device 430 and a second connecting rod 440. The second telescopic driving device 430 is fixedly connected to the frame 100; the first end of the second connecting rod 440 is movably connected to the upper hot plate 410, and the second end of the second connecting rod 440 is movably connected to the driving end of the second telescopic driving device 430; the middle part of the second connecting rod 440 is rotatably connected to the frame 100 through a third rotating shaft 441; the side part of the upper hot plate 410 is rotatably connected to the frame 100 through a fourth rotating shaft 411; under the driving action of the second telescopic driving device 430, the second connecting rod 440 rotates around the third rotating shaft 441 to drive the upper hot plate 410 to rotate around the fourth rotating shaft 411 to the third position or the fourth position; when the upper hot plate 410 rotates to the third position (as shown in the attached Fig. 9 As shown in FIG. 1 ), the upper hot plate 410 is in contact with the top side of the mold; when the upper hot plate 410 is rotated to the fourth position (as shown in FIG. Fig.10 As shown), the upper hot plate 410 is released from being mutually fitted with the top side of the mold. In this way, the second telescopic drive device 430 is used as a power source to drive the second end of the second connecting rod 440 to displace, so that the second connecting rod 440 rotates around the third rotation axis 441, thereby displacing the first end of the second connecting rod 440, and then rotating the upper hot plate 410 around the fourth rotation axis 411. When the upper hot plate 410 rotates to the third position, the upper hot plate 410 and the top side of the mold are mutually fitted, so that the upper hot plate 410 can heat and increase the temperature of the top side of the mold to ensure that the technical solution of the present application can be effectively implemented. Among them, the above-mentioned telescopic drive device can select a telescopic cylinder, and the present application does not impose specific restrictions on it.

[0043] In the embodiment, the rotation amplitude β of the upper heating plate 410 around the fourth rotation axis 411 is 120°~150°. In this way, by setting a limit on the rotation amplitude β of the upper heating plate 410, it is ensured that when the upper heating plate 410 is in the third position, it can smoothly fit with the mold, and when the upper heating plate 410 is in the fourth position, the angle between the upper heating plate 410 and the mold is set to be an obtuse angle, so that the upper heating plate can smoothly support the separated first template to prevent the first template from rotating and falling again under its own gravity to fit with the second template.

[0044] Further, a second linear sliding mechanism 450 is provided at the connection between the second connecting rod 440 and the upper heating plate 410. Figure 9-10When the upper heating plate 410 rotates around the fourth rotation axis 411, the connection between the first end of the second connecting rod 440 and the upper heating plate 410 also moves accordingly; to ensure that when the upper heating plate 410 can rotate around the fourth rotation axis 411 smoothly, the connecting rod will not cause any obstruction to it, a linear sliding mechanism needs to be provided at the connection between the second connecting rod 440 and the upper heating plate 410 to achieve adaptive adjustment of the connection position between the second connecting rod 440 and the upper heating plate 410.

[0045] Specifically, the second linear sliding mechanism 450 includes a second slider 451 and a second slide rail 452. The second slider 451 is rotatably connected to the first end of the second connecting rod 440, and the second slide rail 452 is fixedly connected to the upper hot plate 410; the second slider 451 is slidably connected to the second slide rail 452; in this way, through the sliding connection between the second slider 451 and the second slide 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 be displaced along the track direction of the second slide rail 452 to ensure that the technical solution of the present application can be effectively implemented.

[0046] Furthermore, second limit blocks 453 are respectively provided at opposite ends of the second slide rail 452, and the second limit blocks 453 are used to abut against the second slider 451. In this way, the second slider 451 is ensured not to be excessively displaced and separated from the second slide rail 452 by the limiting effect of the second limit blocks 453. At the same time, since the sliding limit position of the second slider 451 can only slide to abut against the second limit blocks 453, the rotation range of the upper heating plate 410 around the fourth rotation axis 411 can be adjusted by adjusting the position of the second limit blocks 453 on the second slide rail 452.

[0047] Furthermore, the third driving mechanism 420 includes a second limit frame 460, and the second limit frame 460 is provided with a second contact sensor 461, and the second contact sensor 461 is electrically connected to 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 limit frame 460 abut against each other, and the upper hot plate 410 and the second contact sensor 461 contact each other. In this way, in order to ensure that the upper hot plate 410 can accurately rotate to the second position, the second limit frame 460 is provided at the second position of the present embodiment. When the upper hot plate 410 rotates to abut against the second limit frame 460, it means that the upper hot plate 410 has rotated to the second position. At this time, the upper hot plate 410 is restricted from continuing to rotate due to the abutment of the second limit frame 460. At the same time, a second contact sensor 461 is set on the second limit frame 460. When the upper heating plate 410 and the second contact sensor 461 contact each other, the second contact sensor 461 sends an electrical signal to the second telescopic driving device 430 to stop the operation of the second telescopic driving device 430, thereby stopping the continued rotation of the upper heating plate 410.

[0048] Furthermore, a plurality of hollow holes 442 are provided in the middle of the second connecting rod member 440; by providing the hollow holes 442 to reduce the overall weight of the second connecting rod member 440, the second telescopic driving device 430 can drive the second connecting rod member 440 to rotate with a smaller driving power, which helps to save energy and labor.

[0049] As a preferred solution 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 includes a lower hot plate 510 and a fourth driving mechanism 520, and the fourth driving mechanism 520 is used to drive the lower hot plate 510 to move to be in contact with the bottom side of the mold, so that the lower hot plate 510 heats and heats the mold; with this arrangement, the lower hot plate 510 is moved to be in contact with the bottom side of the mold by the fourth driving mechanism 520, so that the lower hot plate 510 can heat and heat the mold, wherein a heating device, such as a heating wire, is provided inside the lower hot plate 510, and the lower hot plate 510 is heated by the heating device, and then the mold in contact with the lower hot plate 510 is also heated accordingly, so as to ensure the smooth implementation of the technical solution of the present application, and the structure is simple and practical.

[0050] There are many specific structures of the fourth driving mechanism 520. In this embodiment, the fourth driving mechanism 520 includes a second lifting driving device 530, which is fixedly connected to the frame 100; the driving end of the second lifting driving device 530 is fixedly connected to the lower hot plate 510; in this way, the second lifting driving device 530 is used as a power source to drive the lower hot plate 510 to move upward to fit with the bottom side of the mold, so that the lower hot plate 510 can heat the bottom side of the mold to ensure that the technical solution of this application can be effectively implemented. The lifting driving device can be a lifting cylinder, and this application does not impose specific restrictions on it.

[0051] Furthermore, the fourth driving mechanism 520 includes at least two second lifting driving devices 530, and the at least two lifting driving devices are symmetrically arranged on opposite sides of the bottom of the lower hot plate 510. Such an arrangement makes the left and right forces of the lower hot plate 510 balanced when the lower hot plate 510 performs lifting movement, which is conducive to improving the stability of the lower hot plate 510 when performing lifting movement. In the embodiment, the number of the lifting driving devices is two.

[0052] It should be noted that the reference Fig.12 Since the lower hot plate assembly 500 and the ejector assembly 200 are also arranged at the lower position of the mold, in order to avoid the movement of the lower hot plate 510 and the ejector 210 interfering with each other, the lower hot plate 510 needs to be provided with a vertically penetrating air-avoiding hole 511, which is used for the ejector 210 to pass through, so that the lower hot plate 510 and the ejector 210 can slide against each other through the air-avoiding hole 511, so as to ensure that the movement of the lower hot plate 510 and the ejector 210 does not interfere with each other. At the same time, the first lifting drive device 230 and the second lifting drive device 530 also adopt a staggered distribution arrangement structure.

[0053] In other embodiments, the inner wall of the air avoidance hole 511 and the outer wall of the top rod 210 can be arranged to be in close contact with each other, so that there is a mutual limiting and guiding effect between the air avoidance hole 511 and the top rod 210; in this way, on the one hand, the lower hot plate 510 is used to limit the freedom of movement of the top rod 210, ensuring that the top rod 210 can only be lifted and lowered in the vertical direction under the driving action of the first lifting drive device 230; on the other hand, the top rod 210 is used to limit the freedom of movement of the lower hot plate 510, ensuring that the lower hot plate 510 can only be lifted and lowered in the vertical direction under the driving action of the second lifting drive device 530.
