Description

Technical Field

[0001] This utility model relates to the field of aerogel insulation sheet technology, specifically to an aerogel insulation sheet extrusion molding device that facilitates positioning. Background Technology

[0002] Aerogel insulation sheets are a type of high-efficiency thermal insulation material with extremely low thermal conductivity, excellent high-temperature resistance, thin and light design, outstanding hydrophobicity, dimensional stability and reliability, lightweight design, and suitable flexibility.

[0003] Aerogel insulation sheets are mainly formed by vacuum hot pressing, and the specific steps are as follows:

[0004] Assembly stage: Stack the pre-treated materials in sequence, usually in the order of lower encapsulation film - heat insulation core material - upper encapsulation film. During assembly, ensure that each layer is aligned to avoid misalignment.

[0005] Vacuum hot pressing stage: The assembled semi-finished products are placed into the hot pressing platform of the vacuum hot press machine. The equipment is first evacuated to a high vacuum state of -100MPA to remove the air between the layers. Then the heating system is started, and the temperature is set according to the material characteristics. At the same time, pressure is applied so that the materials of each layer are tightly bonded under the combined action of heat and force.

[0006] While a hot press can hot-press aerogel insulation sheets, it inevitably has shortcomings in practical use. One such shortcoming is the lack of an auxiliary positioning mechanism, which makes it difficult to accurately place the semi-finished products. To address this issue, a convenient positioning aerogel insulation sheet extrusion molding device is proposed to solve the existing problems. Utility Model Content

[0007] To address the shortcomings of existing technologies, this invention provides an aerogel insulation sheet extrusion molding device that facilitates positioning, solving the problem of inaccurate placement of semi-finished products due to the lack of an auxiliary positioning mechanism in the device.

[0008] To achieve the above objectives, this utility model provides the following technical solution: an aerogel insulation sheet extrusion molding device for easy positioning, comprising a base and a sealing frame. The sealing frame is fixedly mounted on the top of the base by a bracket. A hot pressing mechanism is provided inside the sealing frame. A first electric telescopic rod is fixedly connected to the top of the base, and a bearing plate is fixedly connected to the top of the extension end of the first electric telescopic rod. A lower hot pressing plate is installed on the top of the bearing plate. A heat-conducting plate is bolted to the top of the bearing plate and on the surface of the lower hot pressing plate. A positioning mechanism is provided on the top of the heat-conducting plate.

[0009] Preferably, the positioning mechanism includes a slide groove, and a plurality of slide grooves are provided, all of which are opened on the top of the heat-conducting plate. A slide frame is slidably arranged inside the slide groove, and a positioning plate is slidably connected inside the slide frame. A high-temperature resistant spring is fixedly connected between the positioning plate and the slide frame. A threaded sleeve is fixedly connected inside the slide groove, and a threaded rod is threadedly connected inside the threaded sleeve. The end of the threaded rod is rotatably connected to the surface of the slide frame. The top of the positioning plate has an inclined surface.

[0010] Preferably, a sealing groove is provided on the top of the bearing plate, and a sealing gasket is fixedly provided on the bottom of the sealing frame.

[0013] Beneficial effects

[0014] This invention provides an aerogel insulation sheet extrusion molding device for convenient positioning. Compared with existing technologies, it has the following advantages: This invention provides a sliding frame at the end of the threaded rod, and a positioning plate inside the sliding frame, so that several positioning plates can be adjusted in position to facilitate precise pre-positioning of the semi-finished product.

A lower hot pressing plate 6 is installed on the top of the bearing plate 5. A sealing groove 9 is opened on the top of the bearing plate 5. A sealing gasket 10 is fixedly set at the bottom of the sealing frame 2. The hot pressing mechanism 3 includes a second electric telescopic rod 31, which is installed inside the sealing frame 2. An upper hot pressing plate 32 is installed at the bottom of the extension end of the second electric telescopic rod 31. Limiting cylinders 12 are fixedly connected to both sides of the top of the base 1. Limiting sliding columns 13 that slide and adapt to the limiting cylinders 12 are fixedly connected to both sides of the bottom of the bearing plate 5. The upper hot pressing plate 32 and the lower hot pressing plate 6 are both electrically heated. A vacuum tube port is connected to one side of the sealing frame 2.

[0022] For ease of assembly and disassembly, a heat-conducting plate 7 is bolted to the top of the bearing plate 5 and to the surface of the lower hot press plate 6.

[0023] Furthermore, to facilitate frequent placement of products of the same specifications and provide precise positioning guidance, a positioning mechanism 8 is provided on the top of the heat-conducting plate 7. The positioning mechanism 8 includes a slide groove 801, and several slide grooves 801 are provided, all of which are located on the top of the heat-conducting plate 7. A slide frame 802 is slidably arranged inside the slide groove 801. A positioning plate 803 is slidably connected inside the slide frame 802.
