[0037] The technical solutions in the utility model will be clearly and completely described below in combination with the drawings in the utility model. Obviously, the described is only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by the ordinary skilled in the art without making creative efforts belong to the protection scope of the utility model.

[0039] 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", "second" can explicitly or implicitly include at least one of the features. In addition, the technical solutions of each embodiment can be combined with each other, but it must be based on the fact that the ordinary skilled in the art can realize it, 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.

[0040] In the prior art, the mold opening is in a manual opening mode, and the operator needs to apply a force away from the second mold plate to the first mold plate by means of a long steel rod or the like to separate the first mold plate and the second mold plate, so that the operator 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.

[0041] In order to solve the above technical problems, the utility model provides a mold opening structure applied to a mold opening device, the mold opening device is used for opening the mold, and the mold comprises a first mold plate and a second mold plate which can be separated from each other;

[0042] Please refer to Figure 1 In an embodiment of the utility model, the mold opening structure comprises:

[0043] The rack 100 is used for bearing the mold (not shown in the drawing);

[0044] The clamping assembly 300 is rotatably arranged on one side of the rack 100; the clamping assembly 300 is used for clamping and moving the first mold plate, so that the first mold plate is separated from the second mold plate.

[0045] During operation, the mold is moved from the rubber injection machine to the rack 100 located at the material taking station for bearing, then the first mold plate is clamped and rotated by the clamping assembly 300, so that the first mold plate and the second mold plate are separated from each other, so that the operator can take out the rubber product located in the cavity area of the second mold plate; since the separation process of the first mold plate and the second 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.

[0046] As a preferred solution of the above embodiment, reference is made to the accompanying drawings Figures 6-7 The mold opening structure further comprises an ejection assembly 200, which is arranged on the rack 100; the ejection assembly 200 is used to release the connection between the first mold plate and the second mold plate.

[0047] Specifically, the ejection assembly 200 is located below the mold; the ejection assembly 200 comprises a top rod 210 and a first driving mechanism 220, and the second mold plate is provided with a through hole for the top rod 210 to pass through; the first driving mechanism 220 is used to drive the top rod 210 to move upward, so that the top rod 210 passes through the through hole of the second mold plate and drives the first mold plate to move upward, so that the connection between the first mold plate and the second mold plate is released. It can be understood that when the top rod 210 passes through the through hole of the second mold plate, it will abut against the first mold plate, and as the first driving mechanism 220 continues to drive the top rod 210 to move upward, the top rod 210 will drive the first mold plate to move upward away from the second mold plate, so as to achieve the purpose of releasing the connection between the first mold plate and the second mold plate; in this way, considering that the first mold plate and the second mold plate are commonly connected to each other by a plurality of guide columns, the guide columns are used to ensure that the first mold plate and the second mold plate can be positioned accurately when the mold is closed. However, since the first mold plate needs to be rotated and separated in the present application, in order to avoid the guide columns from causing obstruction, the ejection assembly 200 is used to move the first mold plate away from the second mold plate by a certain distance, so as to ensure that the guide columns do not simultaneously connect the first mold plate and the second mold plate, i.e., release the connection between the first mold plate and the second mold plate. In the present embodiment, the top rod 210 and the first driving mechanism 220 are combined to form the ejection assembly 200, so that the top rod 210 can move upward and pass through the through hole of the second mold plate under the driving action of the first driving mechanism 220, and then lift the first mold plate, so as to ensure the smooth implementation of the technical solution of the present application, and the structure is simple and practical. It can be understood that the lifting height of the first mold plate driven by the top rod 210 should be greater than the height of the guide columns of the mold, so as to ensure that the guide columns do not simultaneously connect the first mold plate and the second mold plate, thereby ensuring that the first mold plate is not hindered by the guide columns during subsequent rotation.

[0048] The first driving mechanism 220 includes a lifting driving device 230 fixedly connected with the rack 100, a driving end of the lifting driving device 230 is connected with the top rod 210 through a driving plate 240, the lifting driving device 230 is arranged as a power source to drive the driving plate 240 to move upward, thereby driving the top rod 210 installed on the driving plate 240 to move upward, so that the top rod 210 can smoothly lift the first mold plate. The lifting driving device 230 can be an oil cylinder, which is not limited in the application.

[0049] Further, the first driving mechanism 220 includes a guide 250 fixedly connected with the rack 100, the guide 250 is provided with a guide hole 251 vertically penetrating through the guide hole 251, and the top rod 210 is slidingly connected in the guide hole 251. In this way, the vertically penetrating guide hole 251 is arranged to guide the movement of the top rod 210 in the vertical direction under the driving action of the lifting driving device 230, so as to avoid the inclination of the top rod 210 during lifting.

[0050] Further, the ejection assembly 200 includes at least two top rods 210, and the at least two top rods 210 are symmetrically arranged on opposite sides of the driving plate 240. In this way, the first mold plate is lifted by the action of the at least two symmetrically arranged top rods 210, so that the force balance on both sides of the first mold plate during lifting is beneficial to improve the stability of the first mold plate during lifting. In the embodiment, four top rods 210 are arranged in a square on the driving plate 240.

[0051] As a preferred scheme of the above embodiment, reference is made to the accompanying drawings Figures 3-4 The clamping assembly 300 includes a turnover plate 310 and a second driving mechanism 320, the turnover plate 310 is used to be connected with the first mold plate, and the second driving mechanism 320 is used to drive the turnover plate 310 to rotate away from the second mold plate, so as to separate the first mold plate from the second mold plate. In this way, the second driving mechanism 320 first rotates the turnover plate 310 to be connected with the first mold plate, and then rotates the turnover plate 310 away from the second mold plate. Since the turnover plate 310 is connected with the first mold plate at this time, the first mold plate is rotated away from the second mold plate, so as to separate the first mold plate from the second mold plate. The cavity region of the second mold plate is completely exposed, so as to facilitate the operator to take out the rubber product in the cavity region, thereby ensuring the smooth implementation of the application, and the structure is simple and practical.

[0052] The second driving mechanism 320 includes a lifting driving device 330 fixedly connected with the rack 100, a driving end of the lifting driving device 330 is connected with the turnover plate 310 through a driving plate 340, the lifting driving device 330 is arranged as a power source to drive the driving plate 340 to rotate, thereby driving the turnover plate 310 to rotate.Figures 3-4 The second drive mechanism 320 includes a telescopic drive device 330 and a connecting rod 340. The telescopic drive device 330 is fixedly connected to the frame 100. The first end of the connecting rod 340 is movably connected to the tilting plate 310, and the second end of the connecting rod 340 is movably connected to the drive end of the telescopic drive device 330. The middle part of the connecting rod 340 is rotatably connected to the frame 100 via a first rotating shaft 341. The side of the tilting plate 310 is rotatably connected to the frame 100 via a second rotating shaft 311. Under the driving action of the telescopic drive device 330, the connecting rod 340 rotates around the first rotating shaft 341, thereby driving the tilting plate 310 to rotate around the second rotating shaft 311 to a first position or a second position. When the tilting plate 310 rotates to the first position (as shown in the attached diagram), Figure 3 As shown), the first template is close to the second template; when the flip plate 310 rotates to the second position (as shown in the attached diagram), Figure 4 As shown, the first template is moved away from the second template so that the mold cavity area of ​​the second template is exposed. With this configuration, the first telescopic drive device 330 acts as a power source to displace the second end of the first connecting rod 340, causing the first connecting rod 340 to rotate around the first rotation axis 341. This displacement of the first end of the first connecting rod 340, in turn, causes the flipping plate 310 to rotate around the second rotation axis 311. When the flipping plate 310 rotates to the first position, the first template is close to the second template, and the mold cavity area of ​​the second template is not exposed. Then, the flipping plate 310 is connected to the first template so that it can subsequently drive the first template to rotate. When the flipping plate 310 rotates to the second position, the first template is moved away from the second template, and the mold cavity area of ​​the second template is exposed. This facilitates the operator's handling of the rubber products in the mold cavity area. In this embodiment, the telescopic drive device 330 can be a telescopic hydraulic cylinder; this application does not impose specific limitations on it.

[0053] In this embodiment, the rotation range θ of the flip plate 310 around the second rotation axis 311 is 110°~130°. By limiting the rotation range θ of the flip plate 310, when the flip plate 310 is in the second position, the first template is located outside the area directly above the second template, thereby ensuring that the mold cavity area of ​​the second template is completely exposed.

[0054] Further, see Appendix Figures 2-5 A linear sliding mechanism 350 is provided at the connection between the connecting rod 340 and the tilting plate 310; for this configuration, please refer to the attached document. Figures 3-4When the turnover plate 310 rotates around the second rotation shaft 311, the connection between the first end of the connecting rod 340 and the turnover plate 310 also moves; in order to ensure that the turnover plate 310 can smoothly rotate around the second rotation shaft 311, the connecting rod 340 cannot hinder it, a linear sliding mechanism 350 needs to be arranged at the connection between the connecting rod 340 and the turnover plate 310 to realize the adaptive adjustment of the position of the connection between the connecting rod 340 and the turnover plate 310.

[0055] Specifically, the linear sliding mechanism 350 includes a first sliding block 351 and a first sliding rail 352 that are slidably connected to each other, wherein the first sliding block 351 is rotatably connected to the first end of the connecting rod 340, and the first sliding rail 352 is fixedly connected to the turnover plate 310; in this way, through 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 shaft 311, the connection between the first end of the connecting rod 340 and the turnover plate 310 can move along the second sliding rail 383 to ensure that the technical solution of the present application can be effectively implemented.

[0056] Further, referring to the accompanying drawings Figures 2-5 The opposite ends of the first sliding rail 352 are respectively provided with limit blocks 353, and the limit blocks 353 are used to abut against the first sliding block 351. In this way, through the limiting effect of the limit blocks 353, it is ensured that the first sliding block 351 cannot displace excessively and be separated from the first sliding rail 352, and at the same time, since the sliding limit position of the first sliding block 351 can only slide to abut against the limit blocks 353 on both sides, the rotation amplitude range of the turnover plate 310 around the second rotation shaft 311 can also be adjusted by adjusting the position of the limit blocks 353 on the first sliding rail 352.

[0057] Further, referring to the accompanying drawings Figure 5, the second driving mechanism 320 comprises a limiting frame 360, the limiting frame 360 is provided with a contact sensor 361, the contact sensor 361 is electrically connected with the telescopic driving device 330; when the turnover plate 310 rotates to the second position, the turnover plate 310 and the limiting frame 360 abut against each other, and the turnover plate 310 and the contact sensor 361 contact each other. By so arranging, in order to ensure that the turnover plate 310 can accurately rotate to the second position, a limiting frame 360 is arranged at the second position of the embodiment, when the turnover plate 310 rotates to abut against the limiting frame 360, it means that the turnover plate 310 has rotated to the second position, at this time, the abutting action of the limiting frame 360 limits the continuous rotation of the turnover plate 310. Meanwhile, the contact sensor 361 is arranged on the limiting frame 360, when the turnover plate 310 and the contact sensor 361 contact each other, the contact sensor 361 sends an electric signal to the telescopic driving device 330 to stop the operation of the telescopic driving device 330, and further stop the continuous rotation of the turnover plate 310.

[0058] Further, with reference to the accompanying drawings Figure 2 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 first mold plate, so that the turnover plate 310 and the first mold plate are connected with each other; the driving end of the position adjusting mechanism 380 is connected with the clamping mechanism 370, and the position adjusting mechanism 380 adjusts the position of the clamping mechanism 370. By so arranging, on the one hand, the position adjusting mechanism 380 is used to drive the clamping mechanism 370 to move to the position of the handle part of the first mold plate, so that the clamping mechanism 370 can smoothly clamp the handle part; on the other hand, considering that the rotation axis of the first mold plate does not coincide with the rotation axis of the turnover plate 310, therefore, in the process of rotating the first mold plate driven by the turnover plate 310, because the rotation radius of the first mold plate is different from the rotation radius of the turnover plate 310, the connection between the turnover plate 310 and the first mold plate will displace with rotation; therefore, the position of the clamping mechanism 370 needs to be adjusted in real time by the position adjusting mechanism 380, so as to ensure that the second mold plate can rotate with the rotation of the turnover plate 310 on the basis of keeping the connection between the turnover plate 310 and the second mold plate.

[0059] Specifically, the clamping mechanism 370 comprises a clamping driving device 371 and two clamping blocks 372 arranged oppositely, the clamping driving device 371 is used to drive the two clamping blocks 372 to move close to each other, so that the two clamping blocks 372 combine with each other to clamp the handle part; by so arranging, 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 first mold plate, which is simple in structure and high in practicability. In the embodiment, the clamping driving device 371 can be selected as a clamping cylinder, which is not limited in the application.

[0060] Specifically, the position adjusting mechanism 380 comprises a displacement driving device 381, a second sliding block 382 and a second sliding rail 383; the displacement driving device 381 is used to drive the second sliding block 382 to slide along the second sliding rail 383; the second sliding block 382 is fixedly connected with the clamping mechanism 370; and the second 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 used as a power source to drive the second sliding block 382 to displace along the track of the second sliding rail 383, so as to adjust the position of the clamping mechanism 370 installed on the second sliding block 382 until the clamping mechanism 370 moves to the position of the handle part, so that the clamping mechanism 370 can subsequently clamp the handle part; on the other hand, during the rotation of the first 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 second sliding block 382 and the second sliding rail 383 are in an automatic sliding state, so that the position of the clamping mechanism 370 can be adaptively adjusted along the track of the second sliding rail 383, thereby achieving the purpose of real-time adjustment of the position of the clamping mechanism 370.

[0061] In the embodiment, the displacement driving device 381 can be a telescopic cylinder, and the application does not make specific limitations thereto. The telescopic cylinder is controlled by a three-position five-way spool valve, when the displacement driving device 381 needs to be set to be in a non-working state, the electromagnetic valve of the telescopic cylinder is switched to the middle position to vent, so that the second sliding block 382 is in a floating state, thereby enabling the second sliding block 382 to be adaptively adjusted along the track of the second sliding rail 383, so as to ensure the smooth implementation of the embodiment.
