Description

Technical Field

[0001] This utility model relates to the field of tire production equipment, and in particular to a preheating device for preheating tire molds. Background Technology

[0002] In existing tire vulcanization production processes, the vulcanization process requires reaching a certain temperature before it can proceed. This means that the tire molds used to hold the raw tires must also reach a specific temperature. There are two conventional methods for preheating the tire molds: one is direct preheating on the vulcanizing equipment, and the other is preheating on a separate preheating unit, thus shortening the working time on the vulcanizing equipment and improving production efficiency. However, in existing preheating units, the handling of tire molds relies entirely on manual labor to move them from the preheating unit to a transport vehicle, and then from the transport vehicle to the vulcanizing equipment. This is inefficient, physically demanding, and poses certain safety hazards. Summary of the Invention

[0003] To solve the above-mentioned technical problems, this utility model provides a preheating device for preheating tire molds, including a base, a frame movably mounted on the base, a translation drive mechanism that can drive the frame to move, the frame moving between a first clearance position and the upper and lower positions of the mold; an upper heating component mounted on the frame, the upper heating component being movable up and down via a lifting drive mechanism, the upper heating component moving between a second clearance position and the mold heating position; and a positioning mechanism, and a mold placement tray that can be precisely positioned with the positioning mechanism, the mold placement tray being transported by a handling tool.

[0004] Preferably, the lifting drive mechanism includes a lifting drive source fixedly mounted on the frame, and a guide mechanism driven by the lifting drive source, wherein the end of the guide mechanism away from the lifting drive source is connected to the upper heating component.

[0006] Preferably, the upper heating assembly includes a heating plate, a heating element disposed on the heating plate, and a heat-conducting plate connected to one end of the heating plate near the positioning mechanism. It also includes a heat-insulating cover connected to the heating plate. The heat-insulating cover and the heat-conducting plate form a mold accommodating space for accommodating the tire mold.

[0007] Preferably, the mold placement tray includes a main support component, which has a accommodating space for supporting and transporting tools. A centering component for centering the tire mold is provided on the end of the main support component that contacts the tire mold, and a plurality of first positioning components are provided on the end of the main support component that is away from the tire mold.

[0008] Preferably, the first positioning component is a hollow structure, and the first positioning component is provided with a first guide end for guiding the positioning mechanism and a first positioning end that cooperates with the positioning mechanism.

[0009] Preferably, the first positioning element is disposed within the main support component, and the main support component is provided with a mounting hole, the mounting hole having a first mounting end for setting the first positioning element and a clearance end for accommodating the positioning mechanism.

[0010] Preferably, the mold placement tray further includes a heat insulation component, a protective layer disposed above the heat insulation component, and an adjustment component sleeved outside the centering component.

[0013] This invention primarily designs a preheating device for tire molds. It utilizes a movable frame and a movable upper heating component, along with a precise positioning mechanism and a mold placement tray. This allows for the transport and conveying of both preheated and unpreheated tire molds using handling equipment, achieving a high degree of automation.

[0024] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0025] like Figures 1 to 10 As shown, this utility model discloses a preheating device 1 for preheating tire molds, including a base 10, a frame 20 movably mounted on the base 10, and a translation drive mechanism 30 that can drive the frame 20 to move. The frame 20 can be positioned as follows: Figure 1 The first clearance position shown and as follows Figure 2 The mold shown moves between its upper and lower parts; an upper heating assembly 40 is mounted on the frame 20, and the upper heating assembly 40 can move up and down via a lifting drive mechanism 50. The upper heating assembly 40 can be positioned as follows: Figure 2 The second clearance position shown and as follows Figure 3The device moves between the heating positions of the mold shown; it also includes a positioning mechanism 60 and a mold placement tray 70 that can be precisely positioned with the positioning mechanism 60. The mold placement tray 70 transports the tire mold 2, which has been preheated by the preheating device 1, to the tire vulcanizing machine for loading, or transports the tire mold 2 from a designated location such as a warehouse to the preheating device 1 for preheating, using a semi-automatic or automatic handling tool (not shown) such as a forklift or AGV. The preheating device 1 with the above structure can more conveniently handle and preheat the tire mold 2 that needs to be preheated, as well as the preheated tire mold 2, realizing semi-automatic or automatic production of tire preheating, thereby facilitating the fully automated production process of tire vulcanization. The positioning mechanism 60 can be integrally set with the base 10 or separately set.

[0026] The first clearance position, as described in this invention, refers to the position where the frame 20 avoids interference when placing the mold placement tray 70 containing the unheated tire mold 2 onto the positioning mechanism 60, or when removing the mold placement tray 70 containing the preheated tire mold 2 from the positioning mechanism 60. The "mold vertical position" refers to the position where the upper heating component 40 can move vertically to heat the tire mold 2 or not. The second clearance position refers to the position where the upper heating component 40 is not heating the tire mold 2. The "mold heating position" refers to the position where the upper heating component 40 heats the tire mold 2.

[0027] like Figure 3 As shown, the lifting drive mechanism 50 of this utility model includes a lifting drive source 51 fixedly mounted on the frame 20, and a guide mechanism 52 driven by the lifting drive source 51. One end of the guide mechanism 52 away from the lifting drive source 51 is connected to the upper heating assembly 40. The guide mechanism 52 includes a hollow bearing element 521 fixedly mounted on the frame 20 and a guide rod 522 passing through the bearing element 521. One end of the guide rod 522 is connected to the lifting drive source 51, and the other end of the guide rod is connected to the upper heating assembly 40.

[0028] The translation drive mechanism 30 of this utility model includes a translation drive source 31 fixedly mounted on the base 10, and a transmission mechanism 32 driven by the translation drive source 31. The other end of the transmission mechanism 32 is mounted on the frame 20. The transmission mechanism 32 is a sprocket and chain structure, a gear and rack mechanism, or a synchronous belt and synchronous pulley mechanism.

[0029] like Figure 4As shown, the upper heating assembly 40 of this utility model includes a heating plate 41, on which a heating element (not shown) is disposed, and a heat-conducting plate 42 connected to one end of the heating plate 41 near the positioning mechanism 60. It also includes a heat-insulating cover 43 connected to the heating plate 41. The heat-insulating cover 43 and the heat-conducting plate 42 form a mold accommodating space for accommodating a tire mold. Preferably, the heating element is an electric heating wire or an electromagnetic heating wire.

[0030] like Figures 5 to 9 As shown, the mold placement tray 70 of this utility model includes a supporting main component 71. The supporting main component 71 is provided with a accommodating space 711 for placing or supporting AGVs or other handling tools. The handling tools can contact the mold placement tray 70 through the accommodating space 711 to pick up and put down the mold placement tray 70. A centering component 72 for centering the tire mold 2 is provided on the end of the supporting main component 71 that contacts the tire mold 2. A plurality of first positioning components 73 are also provided on the end of the supporting main component 71 away from the contact with the tire mold 2. The first positioning components 73 are used to cooperate with the positioning mechanism 60 so that when the mold placement tray 70 is placed in the preheating device 1 to heat the tire mold, the position of the mold placement tray 70 is fixed. The first positioning components 73 are arranged opposite to the positioning mechanism 60, and the number of the first positioning components 73 can be one or more.

[0031] The centering component 72 has a centering surface 721 that mates with the bottom of the tire mold. Preferably, the centering component 72 can be cylindrical or a hollow annular structure. When the centering component 72 is a hollow annular structure, it can effectively reduce the total weight of the entire mold placement tray 70. The centering surface is circular, which better mates with the circular bottom of the tire mold, so that when the tire mold is placed on the mold placement tray 70, the tire mold is fixed and will not move. It should be noted that when the centering surface mates with the bottom of the tire mold, the tire mold 2 will not move left or right, but the tire mold 2 can easily move upward, that is, the tire mold 2 can easily separate from the centering component.

[0032] Preferably, the first positioning member 73 is a hollow structure, and a first guide end 731 for guiding the positioning mechanism 60 and a first positioning end 732 that cooperates with the positioning mechanism 60 are provided inside the first positioning member 73. When the mold placement tray 70 is placed on the positioning mechanism 60 from top to bottom, the positioning mechanism 60 enters the first positioning member 73 through the guidance of the first guide end 731, so that the first positioning end 732 makes good contact with the positioning mechanism 60 for positioning.

[0033] Preferably, for a more rational layout, the first positioning element 73 is disposed within the supporting main component 71. The supporting main component 71 has a mounting hole 712, which has a first mounting end 7121 for mounting the first positioning element 73 and a clearance end 7122 for accommodating the positioning mechanism 60. When the mold placement tray 70 is placed on the positioning mechanism 60, the positioning mechanism 60 is guided by the first guide end 731 and positioned within the first mounting end 7121 of the first positioning element and the clearance end 7122 of the mounting hole. The first positioning element 73 can be integrally disposed with the supporting main component 71 or separately disposed.

[0034] It should be noted that since the tire mold has a certain temperature after preheating, to prevent damage to automated guided vehicles (AGVs) due to the temperature of the tire mold, and to prevent the tire mold from cooling down during transportation, the mold placement tray 70 of this invention also includes a heat insulation component 74. The heat insulation component 74 is disposed on the main support component 71 near the end of the tire mold. The heat insulation component 74 is made of heat-insulating material, thereby preventing the temperature of the tire mold from being transferred downwards to the AGV or transport vehicle. During loading and transportation, it effectively prevents the tire mold from cooling down due to energy transfer.

[0035] Because the mold is heavy and the material is hard, in order to prevent the heat insulation material from being crushed or scratched by the mold, the mold placement tray 70 of this utility model is also provided with a protective layer 75 with a certain hardness. The protective layer 75 is disposed above the heat insulation component 74 and is used to contact the tire mold.

[0036] Since the specifications of molds produced by different tire mold manufacturers are not exactly the same, that is, the inner diameter of the circular bottom of the tire mold will vary, in order to make the mold placement plate 70 have a wider range of applications, the mold placement plate 70 of this utility model also includes an adjusting member 76 sleeved outside the centering member 72. Preferably, the adjusting member 76 is a ring structure. When the inner diameter of the circular bottom of the tire mold changes, by replacing the adjusting member 76 with one of different sizes, the adjusting member 76 can better fit with the bottom of the tire mold to achieve position centering.

[0037] like Figure 9 and 10 As shown, preferably, the positioning mechanism 60 of this utility model includes a positioning mechanism body 61 and a plurality of second positioning members 62 disposed on the positioning mechanism body 61. The second positioning member 62 includes a second mounting end 621, a second positioning end 622 that cooperates with the mold placement plate 70, and a second guide end 623. Preferably, the second positioning end 622 is cylindrical, and the second guide end 623 is conical.

[0038] The working principle of the preheating device described in this utility model is as follows: Figure 1 As shown, the frame 20 is located in the first clearance position. The transport tool transports the mold placement tray 70, which contains the tire mold 2, from the designated position to the preheating device 1. Precise positioning is achieved through the first positioning element 73 of the mold placement tray 70 and the second positioning element 62 on the positioning mechanism. Figure 2 and 3 As shown, after the mold placement tray 70 and the positioning mechanism 60 are positioned, the frame 20 moves from the first clearance position to the upper and lower mold position, and the upper heating component 40 moves from the second clearance position to the mold heating position. The tire mold is placed in the mold accommodating space of the upper heating component 40, so that the heat conduction plate 42 in the upper heating component 40 contacts the tire mold 2 on the mold placement tray to preheat the tire mold. After preheating is completed, the upper heating component 40 moves from the mold heating position to the second clearance position, and the frame 20 moves from the upper and lower mold position to the first clearance position. The transport tool transports the mold placement tray 70 loaded with the preheated tire mold to the tire vulcanizing machine for automatic mold loading of the tire mold.

[0039] The preheating device 1 of this utility model, through a movable frame 20 and a movable upper heating component 40, in conjunction with a positioning mechanism 60 and a mold placement tray 70 capable of precise positioning, enables the handling and conveying of unheated and preheated tire molds using transport tools, achieving a high degree of automation. When used with automated guided vehicles (AGVs), it can achieve automated production of preheating and transfer, better realizing the full-process automation of tire vulcanization. The movable frame 20 is achieved through a translation drive mechanism 30, and the movable upper heating component 40 is achieved through a lifting drive mechanism 50. The upper heating component 40, composed of a heating plate 41, a heat-conducting plate 42, a heating element, and a heat insulation cover 43, can better heat and insulate the tire mold. The mold placement tray 70, equipped with a centering component 72 and a first positioning component 73, achieves precise positioning with the tire mold and the positioning mechanism 60, respectively.

Any equivalent changes or alternative technical solutions that can be easily conceived by those skilled in the art under the guidance of the technical content of this application should be included within the protection scope of this application. Therefore, the protection scope of this application should be determined by the protection scope of the claims.
