▎ 摘　　要

NOVELTY - The bottom template clamp comprises a bottom mold clamp for clamping the foaming box body (1). The bottom of the bottom mold clamp is sequentially provided with a wearable layer (2), a heat transmission layer (3), a back elastic layer (4) and a bottom template (5). The foaming box body is set on the wearable layer and matched with the bottom mold clamp to realize die assembly foaming. The material of the wear resistant layer is one or more of viscose Teflon, polytetrafluoroethylene, polyurethane, polyurea and polycarbonate. The material of the heat transfer layer is one or more of aluminium foil, copper graphene, Teflon and polyimide-based thin film. USE - Bottom template clamp for improving refrigerator iron back foaming bubble shrinkage in a refrigerator production enterprise. ADVANTAGE - The bottom template die assembly increases the rebound layer between the bottom template and the foaming box body, the heat transfer layer and the wearable layer interference compensation mode, realizes the refrigerator backplate interference uniform preheating by controlling the anti-elastic layer, heat transmission layer and the thickness of the wear-resistant layer material, realizes interference fit gap adjustment, and realizes backplate foaming quality lifting and product back appearance quality level of refrigerator in winter, and improves the user experience. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a bottom template clamp method for improving refrigerator iron back foaming bubble shrinkage. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of the bottom template clamp for improving refrigerator iron back foaming bubble shrinkage in a refrigerator production enterprise. 1Foaming box body 2Wearable layer 3Heat transfer layer 4Back elastic layer 5Bottom template
