Abstract
This utility model one mould red needle fixture, relates to mould Hardware fitting field, including clamp body, backing pin, adjusting rod and tooth plate；The axial direction of described clamp body offers the installing hole for installation mold red needle；Described tooth plate is placed in described installing hole；Described clamp body is additionally provided with backing pin hole；Described backing pin hole is higher than described tooth plate；Described backing pin hole leads to described installing hole from the rotary surface of clamp body；Regulation chamber it is additionally provided with in described clamp body；Described regulation intracavity is provided with regulation gear；Described regulation gear is reversed by adjusting rod；Described regulation gear engages with described tooth plate and makes described tooth plate move up and down.This mould red needle is reasonable with clamp structure, coordinates closely, it is possible to solve the problem that the red needle of fracture cannot be taken out, it is therefore prevented that structural failure, effectively raise the service life of equipment.
Description
Technical field
This utility model relates to mould Hardware fitting field, particularly relates to a kind of mould red needle fixture.
Background technology
Requisite accessory when that red needle being diel work, belong to removable mould consumptive material, it is mounted in diel and carries out continuous stamping punching press and thrust operation, make machined material occur to separate or plastic deformation, thus the finished product required for obtaining or semi-finished product.Red needle retaining mechanism is mainly used in hard disc magnetic head industry Fine Boring punching operation, uses circular hole line positioning principle to reach the purpose of fixing red needle plus screw lock.Use line positioning principle it cannot be guaranteed that the axiality of red needle, use screw lock can not control dynamics, cause red needle clamping concordance poor.
Utility model content
This utility model is mainly solving the technical problems that provide a kind of mould red needle fixture, and it is reasonable in design, simple in construction, and the red needle solving fracture remains in the problem being difficult in clamp body take out.
For solving above-mentioned technical problem, the technical scheme that this utility model uses is to provide a kind of mould red needle fixture, including clamp body, backing pin, adjusting rod and tooth plate；The axial direction of described clamp body offers the installing hole for installation mold red needle；Described tooth plate is placed in described installing hole；Described clamp body is additionally provided with backing pin hole；Described backing pin hole is higher than described tooth plate；Described backing pin hole leads to described installing hole from the rotary surface of clamp body；Regulation chamber it is additionally provided with in described clamp body；Described regulation intracavity is provided with regulation gear；Described regulation gear is reversed by adjusting rod；Described regulation gear engages with described tooth plate and makes described tooth plate move up and down.
Preferably, the bottom of described clamp body is additionally provided with the radial direction slewing limit portion for installing clamping.
Preferably, the front end of described clamp body is processed as the rotary structure of taper, is also combined with described backing pin in described backing pin hole.
The beneficial effects of the utility model are: providing a kind of mould red needle fixture, it is rational in infrastructure, coordinate closely, it is possible to solve the problem that the red needle of fracture cannot be taken out, it is therefore prevented that structural failure, effectively raise the service life of equipment.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model a kind of mould red needle fixture；
Fig. 2 is the central cross-sectional view of mould red needle fixture；
In accompanying drawing, the labelling of each parts is as follows: 1, clamp body；2, backing pin；3, adjusting rod；4, tooth plate；5, installing hole；6, backing pin hole；7, regulation chamber；8, regulation gear；9, radially slewing limit portion.
Detailed description of the invention
Below in conjunction with the accompanying drawings preferred embodiment of the present utility model is described in detail, so that advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus protection domain of the present utility model is made apparent clear and definite defining.
Referring to attached Fig. 1 and 2, this utility model embodiment includes:
A kind of mould red needle fixture, including clamp body 1, backing pin 2, adjusting rod 3 and tooth plate 4；The axial direction of described clamp body 1 offers the installing hole 5 for installation mold red needle；Described tooth plate 4 is placed in described installing hole 5；Described clamp body 1 is additionally provided with backing pin hole 6；Also being combined with described backing pin 2 in described backing pin hole 6, red needle can be carried out spacing in installing hole by backing pin 2.Described backing pin hole 6 is higher than described tooth plate 4；Described backing pin hole 6 leads to described installing hole 5 from the rotary surface of clamp body；Regulation chamber 7 it is additionally provided with in described clamp body 1；Regulation gear 8 it is provided with in described regulation chamber 7；Described regulation gear 8 is reversed by adjusting rod 3；Described regulation gear 8 engages with described tooth plate 4 and makes described tooth plate 4 move up and down.The bottom of described clamp body 1 is additionally provided with the radial direction slewing limit portion 9 for installing clamping.The front end of described clamp body 1 is processed as the rotary structure of taper.Owing to red needle works at elevated pressures, the problem that fracture often can occur, the red needle of half fracture is difficult to take out in then remaining in fixture.In this structure, by reversing adjusting rod, adjusting rod then can drive regulation pinion rotation, and on the premise of regulation gear is tooth plate engagement, tooth plate moves up along installing hole, and the fracture red needle remained in installing hole will be ejected by tooth plate.This mould red needle is reasonable with clamp structure, coordinates closely, it is possible to solve the problem that the red needle of fracture cannot be taken out, it is therefore prevented that structural failure, effectively raise the service life of equipment.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every equivalent structure utilizing this utility model description to be made or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical fields, the most in like manner it is included in scope of patent protection of the present utility model.
