Energy-saving auxiliary frame mould

Abstract

The invention discloses an energy-saving auxiliary frame mould comprising a mould head used for extrusion molding, and a stock mould and a water cooling box which are in butt joint with the mould head. The mould head is provided with a machine neck of which the tail end is provided with a shunt support plate, a mandril support plate, a compressing plate, a performing plate and a forming plate by lock screws in sequence, and the middle part of the machine neck is provided with a shunt cone, an internal flow passage and a main core; and the front end side of the main core is provided with another smaller core which extends into the stock mould. The stock mould is internally provided with a setting cavity of which the shape is the same as the shape of a workpiece, and the inner wall of the setting cavity is provided with a vacuum gas groove which communicates with the setting cavity; and the side of the vacuum gas groove is provided with a plurality of cooling water channels. An output port, relative to the stock mould, of the water cooling box is provided with an input port of which the shape is the same as the shape of the workpiece. Energy-saving auxiliary frame profiles produced with the mould disclosed by the invention have the advantages of high static bending intensity, low rate of change in size after heating, energy saving, environmental protection, etc., and the problemsof obvious thermal expansion and contraction and easy deformation of a previous mould are solved.

Description

【Technical field】 [0001] The invention relates to the technical field of plastic profile production equipment, in particular to an energy-saving framed mold. 【Background technique】 [0002] The traditional door and window installation method belongs to wet installation. After the door and window openings of the building are completed, the door and window construction personnel directly install the main frame, and finally install the door and window glass and seal it with glue in the later stage of decoration. However, there is a long period of time between the completion of the installation of the main frame of doors and windows and the later stage of decoration. The main frame of doors and windows is exposed to the construction site for a long time, and it will inevitably be affected by other constructions, resulting in damage, deformation, and surface corrosion of the frame. and pollution issues. 【Content of invention】 [0003] In view of this, in order to overcome the ...
