Abstract
The utility model discloses a device for shearing in a die of an extruder. The device comprises a driving device and a top shaft connected with the driving device, wherein the end part of the top shaft is provided with a shear knife; the shear knife is opposite to a die cushion between the extruder die and a front plate; during shearing, the shear knife passes through a die holder support and then extends into the die cushion to shear a material. According to the device for shearing in the die of the extruder, the material is sheared in the die cushion through the shear knife before the die needs to be replaced, and a remained finished product is taken out easily from the outlet of the front plate of the extruder, so that the die can be replaced easily by overcoming the friction force of a die holder via the thrust force of a die replacing oil cylinder, a die carrier for fixing the die replacing cylinder is prevented from being damaged easily, and the running stability and reliability of equipment is ensured; meanwhile, the size of the entire die replacing cylinder can be reduced, and the aim of saving cost is fulfilled.
Description
Technical field
The utility model relates to a kind of extruder, relates in particular to shear in a kind of extruder mould.
Background technology
At present, traditional extruder is when die change, and for die holder is released, the thrust of die change oil cylinder must overcome the disruptive force that makes material that the yield strength of material produces and the frictional force of die holder, long-term to the fixing mould bases of die change cylinder, can produce fatigue, easily damage in the past.
Utility model content
The purpose of this utility model is to provide shear in a kind of extruder mould, and it has the easily quick and reliable feature of stable equipment operation of die change, to solve the problem that in prior art, extruder die change exists.
For reaching this object, the utility model by the following technical solutions:
Shear in a kind of extruder mould, it comprises drive unit and the apical axis being connected with drive unit, the end of described apical axis is provided with shear knife, wherein, between the corresponding extruder mold of described shear knife and header board, install the position of die-cushion, during shearing, described shear knife stretches into and in die-cushion, cuts off material through die holder lower support.
Especially, described drive unit is arranged on mount pad, and described mount pad is installed on the extruder header board of extruder mold below, and during shearing, shear knife is sheared material from bottom to top through die holder lower support.
Especially, described drive unit is oil cylinder, comprises cylinder body, piston, piston rod and upper and lower end cap, and described piston seal is arranged in cylinder body and connects one end of piston rod, the other end of described piston rod connects apical axis, and described upper and lower end cap is seal-installed on the two ends of cylinder body.
Especially, on described oil cylinder, be provided with sensor.
The beneficial effects of the utility model are, compared with prior art in described extruder mould shear at needs more before mold exchange, by shear knife, material is cut off in die-cushion, from extruder, plate exit easily takes out residue finished product, the frictional force that the thrust of die change oil cylinder only need overcome die holder so just can reach light die change, thereby make mould bases not fragile of fixing die change cylinder, guaranteed the stable and reliable operation of equipment, the size that simultaneously can also integral body reduces die change cylinder, reaches cost-saving object.
Accompanying drawing explanation
Fig. 1 is the scheme of installation of shear in the extruder mould that provides of the utility model specific embodiment 1;
Fig. 2 is the structural representation of shear in the extruder mould that provides of the utility model specific embodiment 1.
The specific embodiment
Below in conjunction with accompanying drawing and by the specific embodiment, further illustrate the technical solution of the utility model.
Refer to shown in Fig. 1 and Fig. 2, in the present embodiment, in a kind of extruder mould, shear comprises driving oil cylinder 1, apical axis 2 and shear knife 3, described driving oil cylinder 1 is arranged on mount pad 4, described mount pad 4 is installed on the extruder header board 6 of extruder mold 5 belows, described driving oil cylinder 1 comprises cylinder body 7, piston 8, piston rod 9, upper end cover 10 and bottom end cover 11, described piston 8 sealings are arranged in cylinder body 7 and connect one end of piston rod 9, the other end of described piston rod 9 connects apical axis 2, the end of described apical axis 2 is provided with shear knife 3, described upper end cover 10 and bottom end cover 11 are seal-installed on the two ends of cylinder body 7, and on described bottom end cover 11, sensor 12 is installed.
Between the corresponding extruder mold 5 of described shear knife 3 and extruder header board 6, install the position of die-cushion 13, and during shearing, described shear knife 3 stretches into and in die-cushion 13, cuts off material 15 from bottom to top through die holder lower support 14.
Above embodiment has just set forth basic principle of the present utility model and characteristic; the utility model is not limited by above-mentioned example; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various variations and change, and these variations and change all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
