Description

Can regulate the polystyrene extruded plastic foam pipe mould of mould outlet gap size

Technical field

What the present invention can regulate that the polystyrene extruded plastic foam pipe mould of mould outlet gap size relates to is a kind of polystyrene extruded plastic foam pipe mould, belong to the polystyrol foam material production field, be mainly used in the production of different model polystyrene extruded plastic foam pipe.

Background technology

The mould outlet gap size of polystyrene extruded plastic foam pipe mould in the market is the size at the beginning of the design, can't according to the actual conditions of producing regulate and processing production process in the impurity that the high temperature difficulty is melted in extruder barrel that occurs, therefore can appear at the impurity that the high temperature difficulty is melted in the extruder barrel in the production process and stop up the mould extrusion, the impurity that cleaning high temperature difficulty is melted need be changed the expense plenty of time, can influence production and normally carry out.

Summary of the invention

Purpose of the present invention be exactly at the gap size of in the market polystyrene extruded plastic foam pipe mould can't according to the actual conditions of producing regulate and can't processing production process in the situation of the impurity that the high temperature difficulty is melted in extruder barrel that occurs, a kind of polystyrene extruded plastic foam pipe mould that can regulate the mould outlet gap size is provided, solve and remove the impurity that the high temperature difficulty is melted in extruder barrel in the production process, and regulate the mould outlet gap size according to the situation that goes out pipe and control load.

Can regulate the polystyrene extruded plastic foam pipe mould of mould outlet gap size takes following scheme to realize: the polystyrene extruded plastic foam pipe mould that can regulate the mould outlet gap size has handpiece body, guide pad is housed in the handpiece body, four long locating shafts are housed on the rear end face of handpiece body, die head is pushed down hold-down ring and is connected on the handpiece body by screw, (opposite of die head being housed) in handpiece body is fixed on sealing ring I in the handpiece body by sealing ring gland I, II is fixed on sealing ring II on the core by the sealing ring gland, the core dress is inserted in the handpiece body, the core end face flushes with die face, by friction top core is positioned on the handpiece body simultaneously.Four short locating shafts are connected an end of core by fixed plate I, snap ring and snap ring compacting ring.The other end at four short locating shafts is equipped with guide plate, screw mandrel is fixed on the guide plate by thrust ball bearing, bearing holder (housing, cover) and bearing holder (housing, cover) gland, guide plate is sleeved on four long locating shafts on the handpiece body, the other end of four long locating shafts is equipped with fixed plates II, and screw mandrel passes fixed plates II.

Operation principle: the handpiece body that can regulate the polystyrene extruded plastic foam pipe mould of mould outlet gap size is connected on the flange of extruder by screw, the charging aperture of handpiece body is communicated with the discharging opening of extruder, when the difficult impurity that melts appears in the mould outlet place, use the spanner rotary screw rod, screw mandrel drives core integral body and moves along long locating shaft, thereby magnify mould outlet, emit difficulty and melt impurity.

The polystyrene extruded plastic foam pipe mould that can regulate the mould outlet gap size is reasonable in design, compact conformation, it is the production equipment of polystyrene extruded plastic tubing, regulate mouthful size in die slot crack by moving forward and backward of core, solved the polystyrene extruded plastic foam pipe mould outlet in the market described in the background technology gap size can't according to the actual conditions of producing regulate and can't processing production process in the situation of the impurity that the high temperature difficulty is melted in extruder barrel that occurs, it is very convenient to remove the impurity that the high temperature difficulty is melted in the extruder barrel, the change expense is few in a large number, can guarantee to produce and normally carry out; And can regulate the mould outlet gap size according to the situation that goes out pipe and control load.
