Abstract

The invention relates to the technical field of processing of plastic foam, in particular to a mold core for molding of the plastic foam. The mold core comprises a base and a core column fixedly connected on the upper end of the base and also comprises a heat exchanger and cylindrical tin foil paper sleeving the mold core, the top end of the tin foil paper is fixedly connected to the edge of the top end of the core column, the bottom end of the tin foil paper is fixedly connected to the upper end of the base, a condensation tube is arranged between the tin foil paper and the core column, a refrigerant is arranged in the condensation tube, a liquid inlet and a liquid outlet of the condensation tube are both located at the lower end of the base and are connected to the heat exchanger, the base is further provided with a through hole, the upper end of the through hole is located between the tin foil paper and the core column, and the through hole is provided with a valve. The mold core can solve the problem that the mold core provided in prior art is difficultly taken out from the plastic foam.

Description

technical field [0001] The invention relates to the technical field of plastic foam processing, in particular to a mold core for plastic foam molding. Background technique [0002] Plastic foam is a chemical material, its full name is polystyrene foam, it has the characteristics of light weight, firmness, shock absorption, low moisture absorption, easy molding, good water resistance, heat insulation, and low price, and is widely used in packaging , heat preservation, waterproof, heat insulation, shock absorption and other fields. When using plastic foam, it is necessary to choose according to the shape of the item, so that the item can be completely fitted with the plastic foam, so as to better protect and support it. When plastic foam is molded, it is usually a whole piece, so it needs to be cut according to its use to form a specific shape. And because the plastic foam is easily broken, it is easy to cause damage to the plastic foam during the cutting process. Therefore...
