Description

Technical Field

[0001] This utility model relates to the field of heating and forming equipment, and in particular to a multi-mold heating device with a guiding mechanism. Background Technology

[0002] In existing molding equipment, each mold station can be equipped with two sets of molds to process profiles. For example, Chinese Patent No. CN219132932U discloses a multi-mold vulcanizing equipment. This equipment has two molds, and the mold station includes a first lifting mechanism, a second lifting mechanism, a middle plate, an upper heating plate, and a lower heating plate. The first and second lifting mechanisms are respectively located on the upper and lower sides of the middle plate. The upper heating plates are located on the first lifting mechanism and at the lower end of the middle plate, and the lower heating plates are located on the upper part of the middle plate and on the second lifting mechanism. The two molds are respectively located on the lower heating plates. The first lifting mechanism drives the upper heating plate downwards to press against the molds; the second lifting mechanism drives the molds upwards towards the middle plate and presses them against the upper heating plate, enabling simultaneous vulcanization of multiple molds. However, each mold corresponds one-to-one with each set of upper and lower heating plates. The first and second lifting mechanisms move the upper heating plate above the middle plate and the molds below the middle plate towards the middle plate, making the equipment structure complex, energy-intensive, and significantly increasing production costs.

[0003] Therefore, it is necessary to propose a multi-mold heating device with a guiding mechanism to simplify the equipment structure and reduce energy consumption. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a multi-mold heating device with a guiding mechanism.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: A multi-mold heating device with a guiding mechanism is used to heat molds located within a mold station frame. It includes an upper heating plate, a middle heating plate, a lower heating plate, and a heating plate driving mechanism. The upper heating plate is fixedly installed on the top of the mold station frame. The middle heating plate and the lower heating plate are vertically and vertically installed below the upper heating plate. Molds are provided on both the middle heating plate and the lower heating plate. The heating plate driving mechanism is connected to the lower heating plate and is used to drive the lower heating plate to move vertically or vertically toward or away from the upper heating plate, thereby driving the molds on the lower heating plate, the middle heating plate, and the molds on the middle heating plate to move vertically or vertically.

[0006] Preferably, the system also includes a middle plate guiding mechanism, which includes a middle plate limiting block and a middle plate guiding column. The middle plate limiting block is fixedly installed on the mold station frame and located on both sides of the middle heating plate. The middle plate guiding column passes through the middle plate limiting block and is fixedly connected to the middle heating plate.

[0007] Preferably, the system also includes two lower mold fixing plates, a lifting rail, and a pulley assembly. The two lower mold fixing plates are respectively installed on the middle heating plate and the lower heating plate, and a mold is provided above the lower mold fixing plates. The lifting rail is vertically mounted within the mold station frame and is located on both sides of the middle heating plate. The pulley assembly is installed on both sides of the lower mold fixing plates. The pulley assemblies on both sides of the lower mold fixing plates on the middle heating plate are slidably connected to the lifting rail. When the heating plate drive mechanism drives the lower heating plate to move up or down toward or away from the upper heating plate, the two lower mold fixing plates, the pulley assembly, and the lifting rail move up and down with the lower heating plate.

[0008] Preferably, the system also includes a lifting track guiding mechanism, which includes a lifting track limiting block and a lifting track guiding column. The lifting track limiting block is fixedly installed on the module station frame, and the lifting track guiding column passes through the lifting track limiting block and is fixedly connected to the lifting track.

[0009] Preferably, the system also includes a lifting track positioning pin, which is set on the module station frame, and the lifting track has a lifting track positioning pin hole that matches the lifting track positioning pin.

[0010] Preferably, the system also includes mold positioning pins, which are set on the middle heating plate and the lower heating plate, and the lower mold fixing plate is provided with mold positioning pin holes that are compatible with the mold positioning pins.

[0011] Preferably, the heating plate driving mechanism includes two mold opening and closing cylinders and four pressure boosting cylinders. Both the mold opening and closing cylinders and the pressure boosting cylinders are connected to the lower heating plate, and the four pressure boosting cylinders are evenly distributed below the lower heating plate.

[0012] Preferably, the device also includes a closing sensing probe and a closing sensor. The closing sensing probe passes through the upper heating plate, and the closing sensor is installed above the upper heating plate. When the mold on the middle heating plate is in contact with the upper heating plate, the closing sensing probe and the closing sensor are in contact.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: (1) The multi-mold heating device with a guiding mechanism proposed in this application only requires one heating plate driving mechanism to clamp all molds between all heating plates, which simplifies the equipment structure, reduces equipment energy consumption, and guides the middle heating plate through the middle plate guiding mechanism so that the middle heating plate and the mold above it remain stable when moving up and down, ensuring the stable operation of the device and avoiding the problem of uneven heating caused by the relative position shift between the mold and the two adjacent heating plates. It simplifies the equipment structure, reduces energy consumption, and further ensures that each mold is heated evenly and ensures the heating and forming effect, thus solving the problem of complex structure and high energy consumption of existing equipment.

[0014] (2) The multi-mold heating device with a guiding mechanism proposed in this application adopts a lifting rail guiding mechanism to guide the lifting rail, and a lifting rail positioning pin is provided. When the lifting rail descends, the lifting rail positioning pin is located in the lifting rail positioning pin hole. Through the structural design of the lifting rail guiding mechanism and the lifting rail positioning pin, the lifting rail is prevented from deviating during the lifting and moving process, so as to ensure that the lifting rail is connected with the first mold moving rail on one side of the mold station frame, which facilitates the lower mold fixing plate and the mold after heating and forming to be moved out of the mold station frame through the pulley assembly.

[0015] (3) The multi-mold heating device with a guiding mechanism proposed in this application sets mold positioning pins on the lower heating plate and the middle heating plate, which cooperate with the mold positioning pin holes of the lower mold fixing plate to fix the relative positions of the lower heating plate and one of the lower mold fixing plates, and the middle heating plate and the other lower mold fixing plate, so as to avoid the position of the mold shifting during the lifting process. Moreover, by applying pressure through the pressure boosting cylinders evenly set below the lower heating plate, it is ensured that each heating plate is subjected to uniform pressure when clamping the mold, thereby ensuring uniform pressure and heating at each position on the mold and ensuring stable material forming quality in the mold.

The accompanying drawings are merely illustrative to facilitate understanding of the present invention, and their specific proportions can be adjusted according to design requirements. The vertical relationships of relative elements and the definitions of front / back in the graphics described herein should be understood by those skilled in the art to refer to the relative positions of the components; therefore, they can all be flipped to present the same component, and all of this should fall within the scope disclosed in this specification.

[0019] refer to Figures 1 to 5 This application proposes a multi-mold heating device with a guiding mechanism for heating molds 7 located within a mold station frame 11. The device includes an upper heating plate 2, a middle heating plate 3, a lower heating plate 4, a heating plate driving mechanism 5, and a middle plate guiding mechanism. The upper heating plate 2 is fixedly mounted on the top of the mold station frame 11. The middle heating plate 3 and the lower heating plate 4 are vertically and vertically mounted below the upper heating plate 2. Molds 7 are mounted on both the middle heating plate 3 and the lower heating plate 4. The heating plate driving mechanism 5 is connected to the lower heating plate 4 and drives the lower heating plate 4 to move vertically or vertically toward or away from the upper heating plate 2, thereby causing the molds 7 on the lower heating plate 4, the middle heating plate 3, and the molds 7 on the middle heating plate 3 to move vertically or vertically. The middle plate guiding mechanism is installed on both sides of the middle heating plate 3 and guides the middle heating plate 3 during vertical movement. Specifically, the middle plate guiding mechanism includes a middle plate limiting block 61 and a middle plate guiding post 62. The middle plate limiting block 61 is fixedly installed on the mold station frame 11 and located on both sides of the middle heating plate 3. The middle plate guiding post 62 is movably inserted through the middle plate limiting block 61 and fixedly connected to the middle heating plate 3, guiding the middle heating plate 3 when it moves up and down. The multi-mold heating device with a guiding mechanism proposed in this application only requires one heating plate driving mechanism 5 to clamp all molds 7 between all heating plates, simplifying the equipment structure. Furthermore, a middle plate guiding mechanism is installed on the middle heating plate 3. The middle plate guiding mechanism guides the middle heating plate 3, and the heating plate driving mechanism 5 drives the lower heating plate 4 to rise, ensuring that the lower heating plate 4, the molds 7 on the lower heating plate 4, the middle heating plate 3, and the molds 7 on the middle heating plate 3 remain stable when moving up and down, avoiding the relative positional displacement between the molds 7 and the two adjacent heating plates, and preventing uneven heating caused by the displacement of the molds 7 between the heating plates during heating and molding.

[0020] In a specific embodiment, the system further includes two lower mold fixing plates 12, a lifting rail 13, a lifting rail guide mechanism, and a pulley assembly 14. The two lower mold fixing plates 12 are respectively installed on the middle heating plate 3 and the lower heating plate 4, and a mold 7 is provided above the lower mold fixing plates 12. The lifting rail 13 is vertically and vertically mounted within the mold station frame 11 and is located on both sides of the middle heating plate 3. The pulley assembly 14 is installed on both sides of the lower mold fixing plates 12. The pulley assemblies 14 on both sides of the lower mold fixing plates 12 on the middle heating plate 3 are slidably connected to the lifting rail 13. Specifically, the pulley assembly 14 includes a pulley and a pulley seat. The pulley is installed in the pulley seat and is slidably connected to the lifting rail 13. When the heating plate driving mechanism 5 drives the lower heating plate 4 to move up or down toward or away from the upper heating plate 2, the two lower mold fixing plates 12, the pulley assembly 14, and the lifting rail 13 follow the lower heating plate 4 in moving up and down. In the embodiments of this application, refer to Figure 3 The mold station frame 11 is also equipped with a fixed track. A first mold-moving track 91 and a second mold-moving track 92 are respectively located on both sides of the mold station frame 11. The height of the first mold-moving track 91 relative to the ground is greater than the height of the second mold-moving track 92 relative to the ground. The first mold-moving track 91 is connected to the lifting track 13. The pulley assemblies 14 on both sides of the lower mold fixing plate 12 located on the middle heating plate 3 can slide between the first mold-moving track 91 and the lifting track 13. The second mold-moving track 92 is connected to the fixed track. The pulley assemblies 14 on both sides of the lower mold fixing plate 12 located on the lower heating plate 4 can slide between the second mold-moving track 92 and the fixed track. Through the structural design of the first mold-moving track 91, the lifting track 13, and the pulley assemblies 14, the lower mold fixing plate 12 and the mold 7 can move on one side and within the mold station frame 11.

[0021] Specifically, the lifting track guiding mechanism includes a lifting track limiting block 81 and a lifting track guide column 82. The lifting track limiting block 81 is fixedly installed on the mold station frame 11, and the lifting track guide column 82 passes through the lifting track limiting block 81 and is fixedly connected to the lifting track 13 to guide the lifting track 13, preventing the lifting track 13 from deviating during lifting and moving, and facilitating the docking of the lifting track 13 with the first mold moving track 91 on one side of the mold station frame 11 when the lifting track 13 descends. (See reference for more details.) Figure 4 The mold station frame 11 is provided with a lifting rail positioning pin 15, and the lifting rail 13 is provided with a lifting rail positioning pin hole that matches the lifting rail positioning pin 15. When the lifting rail 13 stops descending, the lifting rail positioning pin 15 is located in the lifting rail positioning pin hole to ensure that the lifting rail 13 is connected with the first mold moving rail 91 on one side of the mold station frame 11, so as to facilitate the lower mold fixing plate 12 and the heated mold 7 to be moved out of the mold station frame 11 through the pulley assembly 14.

[0022] For details, please refer to Figure 1 and Figure 2 The middle heating plate 3 and the lower heating plate 4 are provided with mold positioning pins 16, and the lower mold fixing plate 12 is provided with mold positioning pin holes that are adapted to the mold positioning pins 16. When the heating plate driving mechanism 5 drives the lower heating plate 4 to move the middle heating plate 3 up and down, the mold positioning pins 16 are located in the mold positioning pin holes to fix the relative positions of the lower heating plate 4 and the lower mold fixing plate 12 and the middle heating plate 3 and the lower mold fixing plate 12. The middle heating plate 3 is guided in the direction of lifting and moving by the middle plate limiting block 61 and the middle plate guide post 62, so that the middle heating plate 3 and the lower mold fixing plate 12 on the middle heating plate 3 are stable when they are lifted and moved up and down.

[0023] In the embodiments of this application, the lower heating plate 4, the middle heating plate 3, the two lower mold fixing plates 12, the two molds 7, the pulley assembly 14, and the lifting rail 13 move upward. The middle plate guiding mechanism and the lifting rail guiding mechanism guide the middle heating plate 3 and the lifting rail 13 respectively, avoiding the instability of material quality at different positions in the mold 7 during subsequent heating and forming processes due to the offset of the middle heating plate 3 and the lifting rail 13. Moreover, during the rising process, the mold positioning pins 16 on the lower heating plate 4 and the middle heating plate 3 are located in the mold positioning pin holes of the lower mold fixing plate 12 to fix the relative positions of the lower heating plate 4 with one of the lower mold fixing plates 12 and the middle heating plate 3 with the other lower mold fixing plate 12. After descending, the lifting rail positioning pins 15 are located in the pin holes of the lifting rail 13 to ensure that the lifting rail 13 is connected with the first mold moving rail 91 on one side of the mold station frame 11, so as to facilitate the lower mold fixing plate 12 and the heated mold 7 to be moved out of the mold station frame 11 through the pulley assembly 14.

[0024] In a specific embodiment, refer to Figure 1 and Figure 5 The heating plate driving mechanism 5 includes two mold opening and closing cylinders 51 and four pressure boosting cylinders 52. The mold opening and closing cylinders 51 and the pressure boosting cylinders 52 are all connected to the lower heating plate 4, and the four pressure boosting cylinders 52 are evenly distributed below the lower heating plate 4.

[0025] refer to Figure 2 and Figure 3 The multi-mold heating device with a guiding mechanism proposed in the embodiments of this application further includes a closing sensing probe 17 and a closing sensor 18. The closing sensing probe 17 passes through the upper heating plate 2, and the closing sensor 18 is installed above the upper heating plate 2. When the mold 7 on the middle heating plate 3 is in contact with the upper heating plate 2, the closing sensing probe 17 and the closing sensor 18 are in contact. At this time, the lower heating plate 4, the mold 7 on the lower heating plate 4, the middle heating plate 3, and the mold 7 on the middle heating plate 3 are closed with the upper heating plate 2.

[0026] The working process of a multi-mold heating device with a guiding mechanism proposed in this application is described below.

[0027] During the heating process, when the lower mold fixing plate 12 carries the mold 7 and moves to the lower heating plate 4 and the middle heating plate 3 through the pulley assembly 14, the heating plate drive mechanism 5 works, activating the mold opening and closing cylinder 51. The mold opening and closing cylinder 51 drives the lower heating plate 4 to move upward toward the upper heating plate 2, and drives the middle heating plate 3, the two lower mold fixing plates 12, the two molds 7, the pulley assembly 14 and the lifting rail 13 to move upward until the mold 7 on the middle heating plate 3 abuts against the upper heating plate 2. At this time, the lower heating plate 4, the mold 7 on the lower heating plate 4, the middle heating plate 3, and the mold 7 on the middle heating plate 3 close with the upper heating plate 2. The closing sensing probe 17 is pushed upward by the mold 7 on the middle heating plate 3 and abuts against the closing sensor 18. After the closing sensor 18 detects the closing sensor probe 17, the mold opening and closing cylinder 51 stops working and the booster cylinder 52 is activated. The booster cylinder 52 applies pressure to the lower heating plate 4 towards the upper heating plate 2 so that the lower heating plate 4, the middle heating plate 3 and the upper heating plate 2 clamp the mold 7 located between the heating plates. The lower heating plate 4, the middle heating plate 3 and the upper heating plate 2 heat the mold 7. Furthermore, since the booster cylinder 52 is evenly distributed at the bottom of the lower heating plate 4, the pressure applied towards the upper heating plate 2 is evenly distributed to ensure the stable molding quality of the material inside the mold 7.

[0028] After heating is complete, the booster cylinder 52 stops working and the mold opening and closing cylinder 51 is activated. The mold opening and closing cylinder 51 drives the lower heating plate 4 to move downward away from the upper heating plate 2, and drives the middle heating plate 3, the two lower mold fixing plates 12, the two molds 7, the pulley assembly 14 and the lifting rail 13 to move downward. During this process, the middle heating plate 3 and the lifting rail 13 move downward smoothly under the guidance of the middle plate guide mechanism and the lifting rail guide mechanism, until the middle heating plate 3 and the lifting rail 13 can no longer descend due to the middle plate limit block 61 and the lifting rail limit block 81, and the lifting rail positioning pin 15 is set in the lifting rail positioning pin hole of the lifting rail 13, so that the lifting rail 13 is connected with the first mold moving rail 91 on one side of the mold station frame 11, so that the lower mold fixing plate 12 and the heated mold 7 can be moved out of the mold station frame 11 through the pulley assembly 14. Then, the opening and closing cylinder 51 continues to drive the lower heating plate 4 and the lower mold fixing plate 12 and mold 7 above it to continue to move downward until the lower heating plate 4 drives the lower mold fixing plate 12 and the pulley assembly 14 on both sides of the lower mold fixing plate 12 back to the fixed track. The lower mold fixing plate 12 above the lower heating plate 4 is slidably connected to the fixed track through the pulley assembly 14 so that the lower mold fixing plate 12 above the lower heating plate 4 can move between the mold station frame 11 and one side of the mold station frame 11 through the pulley assembly 14.

[0029] The above embodiments are only used to further illustrate the technical solution of this utility model, but this utility model is not limited to the embodiments. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall fall within the protection scope of the technical solution of this utility model.
