Description
Technical field
The utility model is related to extrusion die field, more particularly to one kind prevents wide cut section bar extrusion die cavity
The molding machine of deformation.
Background technology
With increase of the market to wide plate demand type, the increasing of product width, the die head designed by usual method
Shape is also widened and is increased therewith, cavity is otherwise caused to deform under extrusion pressure effect because cavity draw ratio is excessive, so as to nothing
Method squeezes out qualified products.But material cost and processing cost that die head size not only increases mold manufacturing producer are increased, simultaneously
Increase section bar manufacturer carry, the difficulty of installation mold, there is no the producer of lifting appliance more especially, mold installation is difficult
Degree greatly improves.For this purpose, market can reduce while not deforming in extrusion there is an urgent need to a kind of guarantee mold
Die boundary dimensions can reduce the molding machine for preventing wide cut section bar extrusion die mold cavity deformation of mold weight again.
Utility model content
The purpose of this utility model be to provide it is a kind of it is simple in structure, cheap, do not deform in extrusion
It can reduce die boundary dimensions simultaneously but also reduce the device of mold weight.
A kind of molding machine for preventing wide cut section bar extrusion die mold cavity deformation of the utility model, including the first die plate and
Second die plate, wherein, several limiting slots, the first die plate and the second mould are respectively equipped on the length direction of the first die plate
The corresponding position of head plate is equipped with the positive stop key mounting groove that is adapted with limiting slot, positive stop key be equipped with positive stop key fixing threaded hole and
Threaded hole is ejected, positive stop key is fixed in positive stop key mounting groove by one end of trip bolt through positive stop key fixing threaded hole, fastens spiral shell
The other end of nail is connect with the second die plate.
As further improvement of the utility model, the height of positive stop key is more than the height of limiting slot.
As further improvement of the utility model, the section of limiting slot is arbitrary in rectangle, circle or ellipse
It is a kind of.
In conclusion the beneficial effects of the utility model are：Width is prevented using one kind described in the utility model
The molding machine of width section bar extrusion die head mold cavity deformation, the first die plate and the second die plate two-by-two in mating surface
Limiting slot or positive stop key mounting groove are set, and make the positive stop key for meeting matching requirements, positive stop key is used with limiting slot, die plate
Trip bolt is fixed, simple in structure, cheap using above-mentioned designing scheme, both ensure that mold was mounted in process of production
Positive stop key in keyway will not fall off, meanwhile, positive stop key again limits the first die plate and the second mould in die head extrusion
The deformation in head plate cavity direction.
Description of the drawings
Fig. 1 is the structure diagram of the utility model；
In figure：1 first die plate, 2 second die plates, 3 limiting slots, 4 positive stop key mounting grooves, 5 positive stop keys, 6 positive stop keys are consolidated
Determine screw hole, 7 trip bolts, 8 ejection threaded holes.
Specific embodiment
The utility model is described further With reference to embodiment：
Embodiment 1
As shown in Figure 1, a kind of molding machine for preventing wide cut section bar extrusion die mold cavity deformation described in the utility model,
Including the first die plate 1 and the second die plate 2, wherein, it is respectively equipped with several limiting slots on the length direction of the first die plate 1
3, the section of limiting slot 3 is rectangle；The corresponding position of first die plate 1 and the second die plate 2 is equipped with and is fitted with 3 phase of limiting slot
The positive stop key mounting groove 4 matched, positive stop key 5 are equipped with positive stop key fixing threaded hole 6 and the ejection threaded hole 8 of itself dismounting, limiting
The height of key 5 is more than the height of limiting slot 3, and positive stop key 5 is fixed on limit by one end of trip bolt 7 through positive stop key fixing threaded hole 6
In position key mounting groove 4, the other end of trip bolt 7 is connect with the second die plate 2.
In conclusion using limiting slot or positive stop key peace is respectively provided in the first die plate and the second die plate two-by-two mating surface
Tankage, and the positive stop key for meeting matching requirements is made, positive stop key is fixed with limiting slot, die plate using trip bolt, in use
It states that designing scheme is simple in structure, cheap, both ensure that the positive stop key that mold is mounted in keyway in process of production will not
It comes off, meanwhile, positive stop key again limits the deformation in the first die plate and the second die plate cavity direction in die head extrusion.
