Description

Technical Field

[0001] This utility model relates to the field of heat insulation sheet production technology, specifically to a stepped hot-pressing sealing heat insulation sheet mold. Background Technology

[0002] Sealing insulation sheets are materials or components that combine sealing and heat insulation functions. They are widely used in industrial equipment, construction, aerospace, electronic devices and other fields to prevent heat transfer (heat insulation) and at the same time block gas or liquid leakage (sealing). Sealing insulation sheets require molds to be produced, and the molds can heat-press the insulation film and sheet together.

[0003] The existing sealing and heat insulation sheet molds have the following problems:

[0004] To facilitate loading and unloading, existing sealing and heat insulation sheet molds require a pushing device. The bottom mold is mounted on a mold platform, which is fixed to the drive belt of the pushing device. The rotating drive belt can push the mold platform for transportation. After running for a period of time, the drive belt may stretch, resulting in loosening. This can cause the bottom mold to misalign with the upper mold after transportation, requiring re-tensioning. However, the existing tensioning method is inconvenient and cumbersome. Utility Model Content

[0005] The purpose of this invention is to provide a stepped hot-pressed sealing and heat-insulating sheet mold to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a stepped hot-pressing sealing and heat-insulating sheet mold, including a fixed platform, a pushing device is provided on the fixed platform, a mold platform is installed on the pushing device, a bottom mold is fixed on the mold platform, a hydraulic press is installed on the fixed platform, a first heater is installed at the lower end of the hydraulic press, a second heater is provided on the hydraulic platform of the hydraulic press, an upper mold is provided on the second heater, a tightening structure is provided on the pushing device, the tightening structure includes an installation box, an installation box is installed on the pushing device, a machine box is installed in the installation box, a rotating column is connected to the machine box, a worm gear is provided on the rotating column, a worm is assembled in the machine box, a rotating frame is installed on the rotating column, a pressure roller is installed in the rotating frame, and a pushing and tightening structure is provided in the installation box.

[0007] Preferably, the push-tightening structure includes a threaded sleeve, the mounting box is provided with a threaded sleeve, a screw is connected in the threaded sleeve, a push block is connected to the end of the screw, a rotating plate is installed in the push block, a torsion spring is installed on the rotating plate, a pressure roller is installed at the end of the rotating plate, and a rotating connecting plate is installed on the push block.

[0008] Preferably, the rotating column extends through the bottom of the housing, and the lower end of the rotating column is rotatably connected to the mounting box.

[0009] Preferably, the diameter of the pressure roller is greater than the width of the rotating frame, and the rotating frame is arc-shaped.

[0010] Preferably, rotating columns are provided at both the front and rear ends of the housing, and the rotating columns at both ends have the same structure. The two rotating columns abut against the front and rear ends of the transmission belt, respectively.

[0011] Preferably, the push block is connected to a rotating connecting plate at both its upper and lower ends, and the other end of the rotating connecting plate is rotatably connected to the mounting box.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] When the belt stretches and becomes loose, requiring tension adjustment, rotating the worm gear causes the rotating column to rotate, causing the pressure roller to press against the belt surface. Under the pressure of the pressure roller, the belt will be squeezed inward and tightened, avoiding the inconvenience of belt tension adjustment. The belt tension adjustment is performed through the tightening structure, and the steps are simple.

[0014] Rotate the screw and push the push block, so that the pressure roller presses on the belt and the rotating wheel. At this time, the torsion spring deforms under force and generates elastic force, which allows the pressure roller to press better on the surface of the belt, making the belt and the rotating wheel fit more tightly, with a higher coefficient of friction, which can greatly reduce the risk of slippage.

Detailed Implementation

[0022] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0023] Please see Figure 1 and Figure 2 This utility model provides a stepped hot-press sealing and heat insulation sheet mold, including a fixed platform 1, a pushing device 2 installed on the right end of the top surface of the fixed platform 1, a mold platform 3 installed on the transmission belt of the pushing device 2, the mold platform 3 being slidably connected to the pushing device 2, a bottom mold 4 fixed on the mold platform 3, a hydraulic press 5 installed on the left end of the top surface of the fixed platform 1, a first heater 6 installed at the lower end of the hydraulic press 5, a second heater 7 provided on the hydraulic platform of the hydraulic press 5, an upper mold 8 provided on the second heater 7, and a tightening structure 9 provided on the pushing device 2.

[0024] Specifically, the first layer of film is placed on the bottom mold 4, a silicone strip is placed on the mold surface, then the sheet is placed, and then the mold is placed on the sheet. Then the pushing device 2 drives the mold table 3 through the transmission belt, thereby sending the bottom mold 4 into the hydraulic press 5 and aligning it with the upper mold 8. The hydraulic press 5 presses the upper mold 8 onto the surface of the bottom mold 4. The first heater 6 and the second heater 7 will heat the heat insulation sheet to perform heat pressing.

[0025] Please see Figure 2 , Figure 3 , Figure 4 and Figure 5 This utility model provides a stepped hot-press sealing and heat insulation sheet mold. The tightening structure 9 includes an installation box 91. The installation box 91 is installed on the pushing device 2. The rotating wheel of the pushing device 2 is located in the installation box 91, so that the transmission belt is located inside the installation box 91.

[0026] The mounting box 91 is fitted with a housing 92 at its top. The front and rear ends of the housing 92 are rotatably connected to rotating columns 93. The rotating columns 93 pass through the bottom surface of the housing 92. The lower end of the rotating columns 93 is rotatably connected to the bottom of the mounting box 91. A worm gear 94 is provided on the rotating columns 93. The worm gear 94 is located inside the housing 92. A worm 95 is rotatably connected in the housing 92. The worm 95 is meshed with the worm gear 94.

[0027] The rotating column 93 is equipped with a rotating frame 96, and a pressure roller 97 is rotatably connected in the rotating frame 96. The diameter of the pressure roller 97 is larger than the width of the rotating frame 96. The rotating frame 96 is arc-shaped to avoid friction caused by the rotating frame 96 contacting the rotating wheel after rotation. The mounting box 91 is equipped with a push-tightening structure 10.

[0028] The housing 92 has rotating columns 93 at both the front and rear ends. The rotating columns 93 at both ends have the same structure. The two rotating columns 93 abut against the front and rear ends of the transmission belt respectively to avoid belt misalignment when pressing the belt.

[0029] Specifically, when the belt stretches and becomes loose, requiring tension adjustment, the worm 95 is rotated. Since the worm wheel 94 is meshed with the worm 95, the rotation of the worm 95 will drive the worm wheel 94 to rotate, thereby driving the rotating column 93 to rotate. The rotating column 93 will drive the rotating frame 96, causing the pressure roller 97 to press against the belt surface. Under the pressure of the pressure roller 97, the belt will be squeezed inward and tightened, avoiding the problem of inconvenient belt tension adjustment. The belt tension adjustment is performed through the tightening structure 9, and the steps are simple.

[0030] Please see Figure 4 and Figure 6 This utility model provides a stepped hot-press sealing and heat insulation sheet mold. The push-tightening structure 10 includes a threaded sleeve 101. The threaded sleeve 101 is installed on the right side of the mounting box 91. A screw 102 is threadedly connected to the threaded sleeve 101. A push block 103 is rotatably connected to the end of the screw 102. A rotating plate 104 is rotatably connected to the push block 103. A torsion spring 105 is installed on the rotating plate 104. One end of the torsion spring 105 is connected to the rotating plate 104, and the other end of the torsion spring 105 is connected to the push block 103. A pressure roller 106 is rotatably connected to the end of the rotating plate 104. A rotating connecting plate 107 is installed on the push block 103.

[0031] The push block 103 is rotatably connected to both its upper and lower ends by rotating connecting plates 107. The other end of the rotating connecting plate 107 is rotatably connected to the mounting box 91. The two rotating connecting plates 107 can ensure the stability of the translation of the push block 103 and provide a more stable limit for the push block 103.

[0032] Specifically, when the screw 102 is rotated, since the screw 102 is threadedly connected to the threaded sleeve 101 and the push block 103 is limited by the rotating connecting plate 107, the push block 103 can be pushed when the screw 102 rotates, so that the pressure roller 106 presses on the belt and the rotating wheel. At this time, the torsion spring 105 is deformed by the force and generates elastic force, so that the pressure roller 106 can press better on the surface of the belt, making the belt and the rotating wheel fit more tightly, the friction coefficient is higher, and the risk of slippage can be greatly reduced.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
