Abstract
The utility model relates to a die head hoisting structure, comprising an extrusion die head and a die head lifting frame, wherein the extrusion die head comprises an upper die head body and a lower die head body, the lower part of the die head lifting frame is provided with a left guide rail and a right guide rail, the upper die head body and the lower die head body are respectively hung below the left guide rail and the right guide rail by virtue of two pulley gears, each pulley gear comprises a pulley and a pulley base, the pulley base is of a 'U' shape and is sheathed on the guide rails, wheel axles at the two ends of the pulley are hinged with an opening at the upper end of the pulley base and are arranged at the upper part of each guide rail in a connecting manner, and the upper die head body and the lower die head body are respectively connected with the lower part of the pulley base by screw threads by virtue of an adjustment screw. The utility model has the advantages that: the die head hoisting structure has simple structure and is convenient to operate and use, a die head moves forward and backward on the lifting frame, the upper die head body and the lower die head body can be beneficially dismounted, so as to be convenient to clean or maintain, thus a roller arranged below the die head can be prevented from being damaged when the die head is dismounted; and relative positions of the die head, a screw connector and a screw can be adjusted by virtue of the adjustment screw.
Description
Technical field
The utility model relates to a kind of mould suspension bracket, particularly a kind of die head hoisting structure.
Background technology
Eva film extrusion die is the core of production line, and its state of the art is directly connected to the stability of extruding production, the quality of extruded product, the production efficiency of extruding production line, and the service life of mould itself.Mould is after use after a while, and is different with resistance because of the wall pressure that different position, material cross section in extrusion die receives, and produces uneven wearing and tearing, causes mass defects such as material bias current, product molding dimension overproof, wall unevenness, bending.Simultaneously, mould in use, and is improper because of loading and unloading, clearing up or maintain, and also causes the extrusion die working face and decomposes face corrosion, fineness decline, generation dead angle, runner joint portion, and it is coarse consequently to extrude EVA film outward appearance, or material lagging and thickener phenomenon take place.Particularly production line stops to produce or mould damages when needing maintenance and repair, must clear up or maintenance and repair extrusion die, and clear up or during maintenance and repair; Need dismantle in pre-installed position this extrusion die; Maintenance for clearance is assembled after accomplishing again, and its weak point is: whole dismounting or assembling process are loaded down with trivial details; And cause easily between the mould or indirectly and damage, cleaning or maintenance and repair time are long.
Summary of the invention
The purpose of the utility model is exactly the weak point in the background technology, and a kind of die head hoisting structure is provided.
For achieving the above object, the utility model adopts following technical scheme: the die head boom hoisting comprises extrusion die; This extrusion die comprises die head body and lower die head body; It also comprises the die head suspension bracket, two guide rails about this die head suspension bracket bottom is provided with, last die head body and lower die head body respectively through about two groups of pulley gears be suspended on about two guide rails below; Said pulley gear comprises pulley, pulley base; This pulley base is " U " shape and is set on the above-mentioned guide rail, and pulley is hinged with pulley base open upper end place and be connected and be positioned at guide rail top, and the said die head body of going up is connected with the pulley base lower thread through the adjusting screw mandrel respectively with the lower die head body.
For a kind of optimization of the utility model, said pulley base bottom is provided with threaded mounting hole, and the threaded mounting hole upper and lower side is respectively equipped with nut, regulates the screw mandrel upper end and is connected with threaded mounting hole through nut respectively.
The utility model is compared with background technology, have simple in structure, the operation and easy to use; Can realize moving before and after die head is on suspension bracket; Help last die head body and the lower die head body dismounting of die head,, thereby prevent that die head from damaging the roller below it when dismounting so that clean or maintenance and repair; Can adjust through the adjustment screw mandrel get to know, the relative position of screw rod connector and screw rod.
