Abstract
The invention discloses an intra-mould shearing device of an extruding machine. The intra-mould shearing device comprises a driving device and an ejection shaft connected with the driving device, wherein the end part of the ejection shaft is provided with a shear knife; the shear knife is mounted corresponding to a position of a mould cushion between an extruding machine mould and a front plate; in a shearing process, the shear knife penetrates through a mould base support and stretches into the mould cushion to cut off materials. Before the mould of the intra-mould shearing device of the extruding machine needs to be replaced, the shearing knife is used for cutting off the materials in the mould cushion and a residual finished product is easily taken out from an outlet of the front plate of the extruding machine, so that the mould can be easily replaced only if friction force of the mould base is overcome by thrust of a mould replacing oil cylinder, and a mould frame for fixing the mould replacing cylinder is not easy to damage and the stable and reliable operation of equipment is guaranteed; meanwhile, the size of the mould replacing cylinder can be wholly reduced and the aim of saving cost is realized.
Description
Technical field
The present invention relates to shear in a kind of extruder, more particularly to a kind of extruder mould.
Background technology
At present, in mold changing, in order to die holder is released, the thrust for changing the mold oil cylinder has to overcome material traditional extruder
The frictional force of the disruptive force and die holder that make material produced by the yield strength of material, long-term mould bases meeting in the past to fixed mold changing cylinder
Fatigue is produced, is easily damaged.
The content of the invention
It is an object of the invention to provide shear in a kind of extruder mould, which has mold changing easily quick and equipment fortune
The characteristics of row is reliable and stable, to solve the problems, such as extruder mold changing in prior art.
It is that, up to this purpose, the present invention is employed the following technical solutions：
Shear in a kind of extruder mould, its apical axis for including driving means and being connected with driving means, the apical axis
End be provided with sheaves, wherein, between sheaves correspondence extruder mold and header board, the position of die-cushion is installed, shearing
When, the sheaves are supported through die holder in stretching into die-cushion and cut off material.
Especially, the driving means are arranged in mounting seat, and the mounting seat is installed on squeezing below extruder mold
On press header board, during shearing, sheaves support through under die holder and from bottom to top material are sheared.
Especially, the driving means are oil cylinder, including cylinder body, piston, piston rod and upper and lower end cap, the piston are close
Envelope is arranged in cylinder body and connects one end of piston rod, the other end connection apical axis of the piston rod, the upper and lower end cover seal
It is installed on the two ends of cylinder body.
Especially, sensor is provided with the oil cylinder.
Beneficial effects of the present invention are that in the extruder mould, shear is needing more mold exchange compared with prior art
Before, material is cut off in die-cushion by sheaves, from before extruder, plate exit easily takes out remaining finished product, so changes the mold oil cylinder
Thrust need to only overcome the frictional force of die holder just to can reach easily mold changing so that the mould bases of fixed mold changing cylinder is hardly damaged,
The stable and reliable operation of equipment is ensure that, while overall the size for changing the mold cylinder can also be reduced, cost-effective purpose is reached.
Description of the drawings
Fig. 1 is the scheme of installation of shear in the extruder mould of the offer of the specific embodiment of the invention 1；
Fig. 2 is the structural representation of shear in the extruder mould of the offer of the specific embodiment of the invention 1.
Specific embodiment
Technical scheme is further illustrated below in conjunction with the accompanying drawings and by specific embodiment.
Refer to shown in Fig. 1 and Fig. 2, in the present embodiment, in a kind of extruder mould, shear includes driving oil cylinder 1, top
Axle 2 and sheaves 3, the driving oil cylinder 1 are arranged in mounting seat 4, and the mounting seat 4 is installed on below extruder mold 5
On extruder header board 6, the driving oil cylinder 1 includes cylinder body 7, piston 8, piston rod 9, upper end cover 10 and bottom end cover 11, the work
8 sealing of plug is arranged in cylinder body 7 and connects one end of piston rod 9, the other end connection apical axis 2 of the piston rod 9, the apical axis
2 end is provided with sheaves 3, and the upper end cover 10 and bottom end cover 11 are seal-installed on the two ends of cylinder body 7, and the bottom end cover
Sensor 12 is installed on 11.
Between the correspondence extruder mold 5 of the sheaves 3 and extruder header board 6, the position of die-cushion 13 is installed, during shearing, institute
State during sheaves 3 support 14 to stretch into die-cushion 13 through under die holder and cut off material 15 from bottom to top.
Above example simply elaborates the ultimate principle and characteristic of the present invention, and the present invention is not limited by above-mentioned example,
Without departing from the spirit and scope, the present invention also has various change and change, and these changes and change both fall within
In scope of the claimed invention.The claimed scope of the invention is by appending claims and its equivalent thereof.
