Abstract
A mold clamping mechanism of an extruder comprises an oil cylinder base plate, a connecting shaft (2), a clamping cylinder, a connecting shaft (9), a crank arm part and mold clamps. The crank arm part is movably connected with the clamping cylinder through the connecting shaft (9), a piston rod is arranged inside the clamping cylinder, a clamping cylinder guide sleeve is arranged between the piston rod and the clamping cylinder, the other end of the clamping cylinder is movably connected with the oil cylinder base plate through the connecting shaft (2), and the mold clamps are arranged below a connecting shaft (12) of the crank arm part. The mold clamping mechanism has the advantages that the mold clamping mechanism is applicable to a horizontal profile extruder, a mold can be clamped better by means of controlling clamping and releasing through an oil cylinder, so that extrusion operation is more reliable and loosening caused by abrasion when in process of cutting off excessive pressure; and further, a mechanical crank arm mechanism is used for clamping the mold when in profile extrusion and excessive cutting processes, and the mold can be changed after the mold clamps are released.
Description
Technical field
The utility model relates to the mould hold down gag of extruder, relates in particular to a kind of extruder mold hold-down mechanism.
Background technology
Extruder is divided into metal extrusion press and two kinds of plastic extruders are dissimilar, and is applied in different industrial circles.Existing this kind mechanism that applies to horizontal section bar extruder is the fixed mould briquetting, and better compaction mold is steady inadequately when extruding simultaneously, and regular meeting causes because of wearing and tearing shearing to press and occurs situation about becoming flexible when surplus, thereby has influenced production efficiency; In addition, also exist defectives such as installation difficult in maintenance, difficult, operation inconvenience.
The utility model content
At above defective, the purpose of this utility model provides a kind of action that helps by oil cylinder and reaches and compress and the extruder mold hold-down mechanism that unclamps, push steadily, can reduce wear, be convenient to installation and maintenance, with many deficiencies of solution prior art.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of extruder mold hold-down mechanism comprises cylinder pedestal plate, connecting axle, compresses cylinder body, connecting axle, crank arm part, clamping cap that the described part of cranking arm flexibly connects with compressing cylinder body by connecting axle, and the described cylinder interior that compresses is provided with piston rod; Described piston rod and compress and be provided with the hold-down cylinder fairlead between the cylinder body; The described cylinder body other end that compresses flexibly connects by connecting axle and cylinder pedestal plate, and described connecting axle bottom of cranking arm part is provided with clamping cap.
The beneficial effect of extruder mold hold-down mechanism described in the utility model is: can be applicable to horizontal section bar extruder, compress and unclamp by oil cylinder control, better compaction mold, more steady when making extruding, and can not cause because of wearing and tearing shear press occur when surplus loosening; In addition, machinery is cranked arm mechanism at extrudate with shear to press when surplus, is used for compaction mold, when the mould briquetting unclamps, and just mold exchange more.
Description of drawings
According to embodiment and accompanying drawing the utility model is described in further detail below.
Fig. 1 is the described extruder mold hold-down mechanism of a utility model embodiment schematic diagram;
Fig. 2 is the part schematic diagram of cranking arm of the described extruder mold hold-down mechanism of the utility model embodiment.
Among the figure:
1, cylinder pedestal plate; 2, connecting axle; 3, compress cylinder body; 4, piston rod; 5, piston head; 6, hold-down cylinder fairlead; 7, trim ring; 8, rod end and cap; 9, connecting axle; 10, the part of cranking arm; 11, connecting axle; 12, connecting axle; 13, clamping cap; 14, compress guide pin bushing.
The specific embodiment
Shown in Fig. 1-2, extruder mold hold-down mechanism described in the utility model, comprise cylinder pedestal plate 1, connecting axle 2, compress cylinder body 3, connecting axle 9, the part of cranking arm 10, clamping cap 13, the described part 10 of cranking arm is by connecting axle 9 and compress cylinder body 3 flexible connections, described cylinder body 3 inside that compress are provided with piston rod 4, and these piston rod 4 head and the tail two ends are respectively equipped with piston head 5 and rod end and cap 8; Described piston rod 4 and compress and be provided with hold-down cylinder fairlead 6 between the cylinder body 3, piston rod 4 outer ends are with trim ring 7; Described cylinder body 3 other ends that compress flexibly connect by connecting axle 2 and cylinder pedestal plate 1 position, and described part 10 bottoms of cranking arm are provided with connecting axle 11 and connecting axle 12 successively, and connecting axle 12 bottoms wherein are provided with clamping cap 13 and its both sides and accompany and compress guide pin bushing 14.
