Description

Technical Field

[0001] This utility model relates to the field of heating and cooling equipment technology, and in particular to a module station with heat insulation protection. Background Technology

[0002] Existing heating and cooling equipment employs a two-station design, with one station for heating and the other for cooling. After material is placed in the mold, it enters the heating station for heating. Once heating is complete, the mold is removed from the heating station and placed in the cooling station for cooling. Finally, the mold is removed from the cooling unit, and the product is taken out of the mold. Heating and cooling equipment typically operates in an open environment, leading to heat dissipation during heating, resulting in prolonged heating time, significant heat loss, low heating efficiency, and difficulty in controlling process time, thus affecting product quality. Furthermore, the heat dissipated during heating causes the ambient temperature to rise due to airflow, impacting the cooling efficiency of the cooling station. All of these factors contribute to increased production costs.

[0003] Therefore, it is necessary to propose a mold station with heat insulation protection to reduce heat loss during mold heating, improve heating efficiency, and reduce costs. Utility Model Content

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: (1) The mold stand with heat insulation protection proposed in this application is equipped with a movable heat insulation device on one side of the heating device. While not affecting the operation of the mold moving device, it can isolate the heating device from the outside when the mold enters the frame for heating, so as to avoid heat loss when heating the mold, improve heating efficiency, and reduce the heat transfer to the cooling device through the air medium, thus avoiding the impact on the cooling efficiency of the cooling device. This solves the problem of large heat loss when heating the mold, improves heating efficiency, and reduces costs.

[0016] (2) The mold station with heat insulation protection proposed in this application is also designed with a mold opening support device to avoid the upper mold of the mold from leaning against the frame and causing wear to the frame when the mold is open.

[0020] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. 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.

[0021] refer to Figures 1 to 5The embodiments of this application propose a mold station with heat insulation protection, which includes a frame 1, a heating device 2, a mold moving device 3, a heat insulation device 4, a lifting drive device 5, a mold opening support device 6, and a cooling device 7. The heating device 2 is installed on the upper part of the frame 1, and the cooling device 7 is located below the heating device 2. The mold moving device 3 and the heat insulation device 4 are installed on one side of the frame 1, and the heat insulation device 4 is located above the mold moving device 3. The lifting drive device 5 connects to and drives the mold moving device 3 and the heat insulation device 4 to move up and down. When the mold moving device 3 is moved to a low position, the heat insulation device 4 is located on one side of the heating device 2, and the mold moving device 3 is located on one side of the cooling device 7. When the mold moving device 3 is moved to a high position, the heat insulation device 4 is located above the heating device 2, and the mold moving device 3 is located on one side of the heating device 2. This application proposes a mold station with heat insulation protection. By designing a heat insulation device 4 on the mold transfer device 3, the heating device 2 is isolated from the outside environment when the mold enters the frame 1 for heating, thus preventing heat loss, improving heating efficiency, and preventing the large amount of heat emitted by the heating device 2 from causing harm to the staff located next to the mold station, thereby improving the safety of the mold station. At the same time, it reduces the heat transfer to the cooling device 7 through the air medium, avoiding affecting the cooling efficiency of the cooling device 7. Furthermore, by installing the heat insulation device 4 on the lifting drive device 5, it rises and falls together with the mold transfer device 3. While isolating the heat from the heating device 2, it does not affect the process of the mold transfer device 3 moving the mold into or out of the frame 1, ensuring work efficiency and strong practicality.

[0022] In a specific embodiment, refer to Figure 1 and Figure 4 The heat insulation device 4 includes heat-insulating glass 41 and two heat-insulating support rods 42. The heat-insulating support rods 42 are mounted on the lifting drive device 5 and are located on the side of the mold transfer device 3 near the frame 1. The heat-insulating glass 41 is installed between the two heat-insulating support rods 42 to separate the open space above the heating device 2 and the mold transfer device 3, reducing heat loss. The mold opening support device 6 includes two mold support frames 61 and a mold support crossbar 62. The mold support frames 61 are fixedly mounted on the lifting drive device 5; the mold support crossbar 62 passes between the two mold support frames 61. In the embodiment of this application, the heat-insulating support rods 42 are fixedly mounted on the mold support frames 61. When the mold transfer device 3 is moved to the low position, the mold transfer device 3 moves the mold at the working position corresponding to the cooling device 7 out of the frame 1 and performs a mold opening operation to remove the product from the mold. When opening the mold, the upper mold can be flipped open relative to the lower mold and rest against the mold support crossbar 62, eliminating the need for manual support of the upper mold and preventing the upper mold from resting against the frame 1 and causing wear to the frame 1.

[0023] In a specific embodiment, refer to Figure 2 and Figure 3The mold-moving device 3 includes a mold-moving support frame 31, a mold frame 32, two first guide rails 33, a mold-moving drive mechanism 34, and a rotating arm 35. The mold-moving support frame 31 is connected to the lifting drive device 5 and is located on one side of the frame 1. The first guide rails 33 are mounted on the mold-moving support frame 31, and the opposite side frames of the mold frame 32 are slidably mounted on the first guide rails 33. One end of the rotating arm 35 is connected to the mold frame 32, and the other end is connected to the mold-moving drive mechanism 34. The mold-moving drive mechanism 34 drives the rotating arm 35 to rotate, thereby moving the mold frame 32 between its working position within the frame 1 and its initial mold-moving position on the mold-moving support frame 31. A heat-insulating support rod 42 is provided near the end of the first guide rail 33 closest to the frame 1. By moving the mold into or out of the frame 1 through the mold-moving device 3, the mold-moving process is automated, improving mold-moving efficiency and thus increasing the working efficiency of the mold station. Further, refer to Figure 3 It also includes a positioning concave shaft 81 and a positioning telescopic shaft 82. The positioning concave shaft 81 is installed on the mold frame 32, and the positioning telescopic shaft 82 is installed on the machine frame 1. When the mold frame 32 is in the working position, the positioning telescopic shaft 82 is locked in the positioning concave shaft 81. Through the structural design of the positioning concave shaft 81 and the positioning telescopic shaft 82, the mold can be moved accurately without manual pushing and pulling to correct the position. The mold can be quickly moved into the working position in the machine frame 1, realizing fast and accurate mold movement.

[0024] In a specific embodiment, refer to Figure 4 The mold support frame 61 is provided with several positioning holes 611 and a crossbar sleeve 621. The positioning holes 611 are arranged along the extension direction of the first guide rail 33. By setting multiple positioning holes 611, the position adjustment function of the mold support frame 61 relative to the frame 1 can be realized, thereby adapting to different mold opening and closing angles, supporting the mold in the mold opening state, reducing wear at the mold opening and closing points, and extending service life. The crossbar sleeve 621 is sleeved on the outside of the mold support crossbar 62 to increase the buffer when the upper mold of the mold flips open toward the mold support frame 61, reducing damage to the mold.

[0025] In a specific embodiment, refer to Figure 2 , Figure 3 and Figure 5 The frame 1 includes a fixed plate 11, a second guide rail 12, and a lifting assembly 13. The heating device 2 includes an upper heating plate 21, a lower heating plate 22, and a heat-locking drive mechanism 23. The lower heating plate 22 is fixedly mounted on the fixed plate 11. The heat-locking drive mechanism 23 is mounted on the top of the frame 1 and connected to the upper heating plate 21. The heat-locking drive mechanism 23 is used to drive the upper heating plate 21 to move toward or away from the lower heating plate 22. The second guide rail 12 is movably mounted on both sides of the fixed plate 11. The lifting assembly 13 is fixedly connected to the second guide rail 12 and detachably connected to the upper heating plate 21. (Refer to...) Figure 3 The lifting assembly 13 is connected to the upper heating plate 21, for reference. Figure 5 When the lifting assembly 13 is separated from the upper heating plate 21, the hot mold-locking drive mechanism 23 drives the upper heating plate 21 to move towards the lower heating plate 22 to the heating position, at which point the upper heating plate 21 separates from the lifting assembly 13. The hot mold-locking drive mechanism 23 then drives the upper heating plate 21 away from the lower heating plate 22 to the heating preparation position, and the mold-moving device 3 moves to the high position. The upper heating plate 21 connects with the lifting assembly 13, the second guide rail 12 and the lifting assembly 13 move with the upper heating plate 21, and the second guide rail 12 moves to a position where it aligns with the first guide rail 33. The mold frame 32 slides on the second guide rail 12 and the first guide rail 33. In the embodiments of this application, the structural design of the upper heating plate 21 and the lifting assembly 13 achieves the function of separating the mold and mold frame 32 from the lower heating plate 22. This prevents wear on the lower heating plate 22 during the operation of moving the mold and mold frame 32 out of the machine frame 1, thus extending the lifespan of the equipment.

[0026] In a specific embodiment, refer to Figure 3 The cooling device 7 includes an upper cooling plate 71, a lower cooling plate 72, a cold mold clamping drive mechanism 73, and a third guide rail 74. The upper cooling plate 71 is fixedly installed at the bottom of the fixed plate 11. The cold mold clamping drive mechanism 73 is installed at the bottom of the frame 1 and connected to the lower cooling plate 72. The cold mold clamping drive mechanism 73 is used to drive the lower cooling plate 72 to move toward or away from the upper cooling plate 71. The third guide rail 74 is fixedly installed on the frame 1. When the mold moving device 3 moves to the low position, the third guide rail 74 is connected to the first guide rail 33.

[0027] In a specific embodiment, refer to Figure 2 and Figure 3 The lifting drive device 5 includes two sprockets 51, a chain 52, a lifting seat 53, a lifting guide column 54, and a lifting drive motor 55. The two sprockets 51 are respectively located at both ends of the lifting guide column 54. The chain 52 is wound around the two sprockets 51. The lifting seat 53 is fixedly connected to the chain 52, the mold moving support frame 31, and the mold template frame 61, and is movably mounted on the lifting guide column 54. The lifting drive motor 55 is connected to one of the sprockets 51 for transmission.

[0028] In the embodiments of this application, mold moving devices 3 can be respectively provided on opposite sides of the frame 1. The two mold moving devices 3 can move the mold frame 32 in the heating working position and the mold frame 32 in the cooling working position at the same time to further improve production efficiency.

[0029] The working principle of this heat-insulated mold station will be explained below, taking as an example a process in which a mold is completed in the mold station with mold moving devices 3 on opposite sides of the frame 1.

[0030] During the mold-feeding process at the heating station, the first guide rail 33 of the mold-moving device 3 located on the first side of the frame 1 connects with the second guide rail 12 inside the frame 1. The mold frame 32 carries the mold on the first guide rail 33. The mold-moving drive mechanism 34 drives the rotating arm 35 to rotate, thereby moving the mold frame 32 from the initial mold-moving position to the working position for heating inside the frame 1. The mold frame 32 is positioned by the positioning concave shaft 81 and the positioning telescopic shaft 82, and the mold is located on the lower heating plate 22. Then, the lifting drive device 5 operates, driving the mold-moving support frame 31 to move downward, causing the rotating arm 35 to separate from the mold frame 32. After the rotating arm 35 separates from the mold frame 32, the lifting drive device 5 continues to drive the mold-moving support frame 31 to move downward, while the mold-moving drive mechanism 34 drives the rotating arm 35 to rotate, so that the entire rotating arm 35 is completely located inside the mold-moving support frame 31, in order to avoid the rotating arm 35 colliding with other mechanisms inside the frame 1 during the downward movement of following the mold-moving support frame 31, thus affecting the operation of the equipment. After the lifting drive device 5 continues to drive the mold moving support frame 31 to the low position, it stops working. At this time, the heat insulation device 4 is located on one side of the heating device 2 to achieve the heat insulation protection function, and the mold moving device 3 is located on one side of the cooling device 7.

[0031] During the heating process, when the mold frame 32, carrying the mold, is positioned above the lower heating plate 22, and the mold is not in contact with the lower heating plate 22, and the upper heating plate 21 is in the heating preparation position, the thermal locking drive mechanism 23 drives the upper heating plate 21 to move towards the lower heating plate 22, and causes the lifting assembly 13 to descend. The second guide rail 12 connected to the lifting assembly 13, the mold frame 32 located on the second guide rail 12, and the mold located within the mold frame 32 descend accordingly until the lifting assembly 13 separates from the upper heating plate 21, and the mold contacts the lower heating plate 22. The thermal locking drive mechanism 23 continues to drive the upper heating plate 21 to move towards the lower heating plate 22 until the upper heating plate 21 presses against the mold, and the upper heating plate 21 is in the heating position. The mold is heated simultaneously by the upper heating plate 21 and the lower heating plate 22.

[0032] During the demolding process at the heating station, after the heating process is completed, the thermal locking drive mechanism 23 drives the upper heating plate 21 to move upward away from the lower heating plate 22. After the upper heating plate 21 moves to the position connected with the lifting assembly 13, it continues to move upward, driving the second guide rail 12 connected to the lifting assembly 13, the mold frame 32 on the second guide rail 12, and the mold inside the mold frame 32 to move upward, separating the mold from the lower heating plate 22. The upper heating plate 21 then stops moving at the heating preparation position. Simultaneously, the lifting drive device 5 drives the mold moving device 3 located on the second side of the frame 1 to rise, where the first side and the second side of the frame 1 are opposite sides. Before the first guide rail 33 of the mold moving device 3 aligns with the second guide rail 12 inside the frame 1, the mold moving drive mechanism 34 drives the rotating arm 35 to rotate so that one end of the rotating arm 35 is below the mold frame 32. The lifting drive device 5 drives the mold moving device 3 to rise until one end of the rotating arm 35 connects with the mold frame 32. The mold transfer drive mechanism 34 drives the rotating arm 35 to rotate, thereby moving the mold frame 32 from the heating working position inside the frame 1 to the initial mold transfer position on the mold transfer device 3.

[0033] During the mold-entry process at the cooling station, the lifting drive device 5 operates, driving the mold-moving device 3, located on the second side of the frame 1 during the mold-removal process at the heating station, to move to a low position. The first guide rail 33 of the mold-moving device 3 aligns with the third guide rail 74 of the cooling device 7. The mold-moving drive mechanism 34 drives the rotating arm 35 to rotate, moving the mold frame 32 from its initial position to a cooling working position within the frame 1. Then, the lifting drive device 5 operates, driving the mold-moving support frame 31 downwards to separate the rotating arm 35 from the mold frame 32. After the rotating arm 35 separates from the mold frame 32, the lifting drive device 5 continues to drive the mold-moving support frame 31 downwards, while the mold-moving drive mechanism 34 drives the rotating arm 35 to rotate, ensuring the entire rotating arm 35 is completely within the mold-moving support frame 31.

[0034] During the cooling process, the cold clamping drive mechanism 73 drives the lower cooling plate 72 to move toward the upper cooling plate 71 until the lower cooling plate 72 presses against the mold, and the mold is cooled by the upper cooling plate 71 and the lower cooling plate 72 at the same time.

[0035] During the mold removal process at the cooling station, the mold transfer device 3, located on the first side of the frame 1, is in a low position during the mold insertion process at the heating station. This mold transfer device 3 is used to perform the mold removal process at the cooling station. After cooling is completed, the lifting drive device 5 operates, first driving the mold transfer device 3 located on the first side of the frame 1 to move downwards, and then driving the rotating arm 35 to rotate via the mold transfer drive mechanism 34 so that one end of the rotating arm 35 is below the mold frame 32. Then, the lifting drive device 5 drives the mold transfer device 3 to rise, so that one end of the rotating arm 35 is connected to the mold frame 32. The mold transfer drive mechanism 34 drives the rotating arm 35 to rotate, thereby moving the mold frame 32 from the cooling working position within the frame 1 to the initial mold transfer position on the mold transfer device 3.

[0036] During the mold opening and closing process, the upper mold is flipped open relative to the lower mold and rests against the mold support crossbar 62 to remove the product from the mold; then new material is placed into the mold and the mold is closed. The lifting drive device 5 operates to drive the mold moving device 3 located on the first side of the frame 1 to rise, and to align its first guide rail 33 with the second guide rail 12 inside the frame 1 to perform the heating station mold entry process.

[0037] 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.
