Interior last carving is divided into two, is easy to the stable lifting of movable part.
Movable part includes a part for foot palm part and leg；Fixed part includes another part of heel portion and leg.Activity
Portion is the side in heel brace portion, and fixed part is that the side of heel portion on heel portion side, interior last carving is comparatively gentle, on movable part
It is easy to drive shoe body together to rise when rising.
The guide groove and sliding block being combined together between fixed part and movable part provided with gap, guide groove is along the bottom of perpendicular to
The direction of seat is set.By setting guide groove and sliding block, it is ensured that the stability of position when movable part is acted, and ordinary circumstance
Under, guide groove and sliding block are swallowtail shape.
Lifter plate is provided with base, movable part is fixed on lifter plate.By setting lifter plate convenient to movable part
It is fixed, it is easy to implement the driving coupling of movable part and elevating mechanism.
The recess for being used for accommodating lifter plate is provided with base, the size of recess is consistent with the size of lifter plate.Lifter plate
It can be fully accommodated in after decline in recess so that compact overall structure is good.
Described elevating mechanism is cylinder, and cylinder is fixed on lifter plate, and the outer end of piston rod passes through lifting in cylinder
Plate and with base phase top pressure.Using cylinder as elevating mechanism, can by way of travel switch or position sensor are set come
Gas circuit to cylinder is controlled, and last carving structure can be arranged on loop wire in this, and can be realized automation and be started cylinder.
The elevating mechanism is the ripping bar being hinged on base, and inner end and the movable part of ripping bar are actively coupled.Pry type
Elevating mechanism be usually to be operated by artificial, movable part is prized by ripping bar and is risen.
Ripping bar includes outer bar, interior bar and switch block, and outer bar is located at the outside of switch block, and interior bar is located at the inner side of switch block, interior bar
Inner end is actively coupled with movable part；Switch block is hinged on base, and gag lever post is threaded with switch block, and gag lever post, which runs through, to be turned
Block, the inner end of gag lever post stretches to pin joint of the switch block on base, for being defined to rotation of the switch block on base.This
Kind ripping bar is simple in construction, compactedness is good, and job stability can be guaranteed.
Compared with prior art, the beneficial effects of the utility model are：Interior last carving is arranged to split-type structural, by fixing
Portion and movable part two parts are constituted, and under the drive of elevating mechanism, movable part can be risen or fallen with the vertical direction.Entering
During row injection shoemaking delasting, can only have movable part and rise and drive shoe body to rise together, shoe body foot is in the top of fixed part
Can be hollow, the shoe body after shaping can be disengaged from interior last carving easily by pulling shoe body from middle vacancy.The application of last carving structure in this, can
To effectively improve the operating efficiency of shoemaking, the cost of shoemaking is reduced.
Brief description of the drawings
Fig. 1 is a kind of structure chart of embodiment of last carving structure in this footwear mould.
Fig. 2 is the structure chart of last carving structure another embodiment in this footwear mould.
Fig. 3 is the structure chart of ripping bar.
Embodiment
See in figure, last carving structure is used in use in this footwear mould and dynamic model is used cooperatively, and dynamic model is interior last carving
The inside is wrapped in, and die cavity is formed between dynamic model inner surface and interior last carving outer surface.Last carving structure is typically provided in loop wire in this
On, under the drive of loop wire, interior last carving is moved between different stations, and realizes injection, solidification and delasting process.
Last carving structure includes base 9 in this, and interior last carving is arranged on base 9, and interior last carving has leg and the pin above leg
Portion, foot has foot palm part 6 and heel portion 5.Interior last carving sheet is as split-type structural, mainly by fixed part 4 and the structure of movable part 7
Into, fixed part 4 and the section that the face that movable part 7 fits is interior last carving, the section simultaneously separates the foot of interior last carving and leg.
It is that the foot of interior last carving is separated, leg is also separated simultaneously.Generally, the face that movable part 7 fits with fixed part 4 is
