Abstract

The invention provides forming equipment of a plastic material filled with polyurethane foam in a core layer, and relates to forming equipment of plastic door and window materials. The forming equipment comprises an extruder, a machine head, a cooling shaping device, tractor and the like, wherein the machine head comprises a shunt body, a template A, a template B, a template C, a core mold and a polyurethane feeding channel; the polyurethane feeding channel is formed in the machine head, and comprises a heat insulating ring, a connecting piece, a polyurethane feeding pipe A, a heat insulating pipe A, a polyurethane feeding pipe B and a heat insulating pipe B; the connecting piece is concentrically and fixedly connected with the polyurethane feeding pipe A and the heat insulating pipe A; the heat insulating pipe A is concentrically and fixedly connected outside the polyurethane feeding pipe A; and a space between the heat insulating pipe A and the polyurethane feeding pipe A is closed or vacuumized. The plastic material produced by the equipment solves the problem of low heat insulation property caused by the cross-ventilation, and improves the heat insulation property, sound insulation effect and structural strength of plastic doors and windows.

Description

technical field [0001] The invention relates to a plastic profile forming equipment with a core layer filled with polyurethane foam, which is mainly used for manufacturing plastic door and window profiles. Background technique [0002] At present, there are many types of plastic door and window profile molding equipment at home and abroad, mainly extruding PVC profiles. When extruding profiles, single extrusion is the main one, and there are also two or three co-extrusion profiles. In the manufacture of plastic doors and windows, in order to increase the strength, the method of placing steel lining in the inner cavity of the plastic profile is adopted. The plastic profile and the steel lining are connected by screws, the strength increase is not high, and the on-site construction is troublesome. In addition, the inner cavity of the plastic profile is due to Air convection reduces the thermal insulation performance and also affects the thermal insulation effect of doors and w...
