Description

Technical Field

[0001] The utility model relates to the technical field of aerogel thermal insulation pads, in particular to a hot pressing device for a pre-oxidized silk aerogel thermal insulation pad. Background Art

[0002] Pre-oxidized fiber, referred to as pre-oxidized yarn, is the basic material for producing carbon fiber. It has good flexibility, high temperature resistance, and does not spread flame. It is mostly used in the production of high-temperature sealing fillers, fireproof and flame-proof materials, heat-resistant fabrics and fillers. It can be added to aerogel thermal insulation pads to improve the thermal insulation effect. Before the production of aerogel thermal insulation pads, it is necessary to place aerogel, silicone frame, and PRT film on the mold frame in sequence, and then the mold frame is hot-pressed to form, and finally the thermal insulation pad is formed on the mold frame. Currently, in the automated production process of thermal insulation pads, the placement position of the mold frame and the hot-pressing position of the mold frame are in the same position. When the position where the mold frame is placed becomes very hot, the operator needs to wait for the temperature at this position to return to normal temperature before continuing the molding operation of the thermal insulation pad, which affects the production efficiency of the thermal insulation pad. Patent documents have been made to improve this.

[0003] Chinese patent CN221067159U discloses a hot pressing device for an aerogel thermal insulation pad, which includes a workbench and a mold frame. A hot pressing station and a loading station are respectively arranged on the workbench, and a clamping arm for reciprocating circular motion is arranged between the hot pressing station and the loading station. Two thermal insulation positioning blocks are respectively arranged on both sides of the mold frame, two hot pressing positioning grooves are respectively arranged on both sides of the hot pressing station, and two loading positioning grooves are respectively arranged on both sides of the loading station. The clamping arm drives the thermal insulation positioning block to reciprocate between the hot pressing positioning groove and the loading positioning groove. The utility model can avoid burns to the operator and ensure the personal safety of the operator.

[0004] Although the clamp arm in the above-mentioned patent drives the heat-insulating positioning block to move back and forth between the hot pressing positioning groove and the loading positioning groove, which can prevent the operator from being burned, the heat of the mold frame will be transferred to the heat-insulating positioning block after the mold frame is hot pressed, causing the heat-insulating positioning block to be hot and hot to pick up, thus affecting the placement and removal of the mold frame. Utility Model Content

[0010] Preferably, a sliding opening is opened on one side of the inner cavity of the limiting groove, and a sliding plate is slidably connected inside the sliding opening.

[0011] Preferably, a strip-shaped slide groove is provided on one side of the sliding plate, and the interior of the strip-shaped slide groove is slidably connected to one side of the mold frame via a sliding block.

[0012] Beneficial Effects

[0013] The utility model provides a pre-oxidized silk aerogel thermal insulation pad hot pressing device. Compared with the existing technology, it has the following beneficial effects:
