Claims

[Scope of Claim for Utility Model Registration] (1) In a mold for thermoforming a thermoplastic synthetic resin sheet using vacuum or compressed air, the mold is slidably provided on the side of the mold equipped with a plug, Prior to caulking the preheated sheet, one mold has a clamp member that presses the flange portion excluding the cavity opening with a flat surface through the sheet, and a plurality of molds One of the molds, which have a seed-shaped cavity cut out and are the same size and the same size, is removably inserted into the mold.
A thermoforming mold characterized by comprising a fixed mold and another mold. (2) A request for utility model registration in which the flat surface of the leading clamp member that presses the flange portion of the cavity is provided with a gap in the thickness direction of the sheet surrounding the outside of the flat surface that presses around the cavity opening. A mold for thermoforming as described in item (1) of the scope.
