Abstract
The utility model discloses a positioning device used for a plastic extrusion die. A die plate at one side is provided with a positioning dowel, and the die plate at the other side is provided with a dowel positioning sleeve at a dowel hole; and a middle hole of the dowel positioning sleeve is a dowel hole. The positioning device adopts the dowel positioning sleeve to be matched with the dowel, thus having convenient primary positioning, simple operation, high positioning accuracy, convenient replacement of the dowel positioning sleeve and high efficiency of assembly operation of dies.
Description
Technical field
The utility model relates to a kind of positioner that is used for plastics extrusion die.
Background technology
Usually all adopt between adjacent two templates of plastics extrusion die and sell the nail location directly to households, promptly on the side template shop bolt is housed, have the pin hole that cooperates with shop bolt on the opposite side template, cooperate with pin hole by pin two templates are positioned.This method positioning accuracy is not high, and replaceability is bad; Particularly pin and pin hole can cause wearing and tearing in the plastics extrusion die cargo handling process, cause the decline of positioning accuracy, need process shop bolt again during replacing.
Summary of the invention
The purpose of this utility model provides a kind of positioner that is used for plastics extrusion die, not only can improve the plastics extrusion die positioning accuracy, and setting element has very high replaceability, thereby can raise the efficiency.
Technical solution adopted in the utility model is: on the side template shop bolt is housed, has the pin hole that cooperates with shop bolt on the opposite side template, template is equipped with the pin positioning sleeve at the pin hole place, and the interstitial hole of pin positioning sleeve is a pin hole.Pin positioning sleeve machining accuracy height, thereby can improve the positioning accuracy of mould, and after the wearing and tearing of the pin hole of pin or pin positioning sleeve, only need to change the pin positioning sleeve and get final product, change conveniently.
Assembling for convenience, pin nose has taper seat, and the pin hole in the pin positioning sleeve has the internal conical surface that cooperates with pin nose.Pin adopts the conical surface to contact with pin cover location, and the taper seat of front end can effectively play the effect of guiding, and operation easily realizes location just.
Change the pin positioning sleeve for convenience, a priority scheme of the present utility model is: in the template pin positioning sleeve installing hole compression spring is housed, stencil sidewalls is equipped with the locking device to pin positioning sleeve axial location.Mould is when dismounting, as long as unclamp the tightening device, spring will reset, and by ejecting in the installing hole, changes very convenient the pin positioning sleeve.
The utility model adopts the pin positioning sleeve to cooperate with pin, and just the location is convenient, and is simple to operate, the positioning accuracy height, and the pin positioning sleeve is changed convenient, mould assembly manipulation efficient height.
Description of drawings:
Fig. 1 is the utility model structural representation.
Fig. 2 is a lower bolster vertical view among Fig. 1.
Among the above-mentioned figure: 1, lower bolster; 2, pin; 3, pin positioning sleeve; 4, spring leaf; 5, lock-screw; 6, cope match-plate pattern; 7, pin installing hole; 8, installing hole; 9, pin hole; 10, internal conical surface.
The specific embodiment
As depicted in figs. 1 and 2, in the pin installing hole 7 on the cope match-plate pattern 6 shop bolt 2 is housed, pin 2 front ends have taper seat, lower bolster 1 has pin positioning sleeve installing hole 8 above pin hole 9, pin positioning sleeve 3 is contained in the installing hole 8, the interstitial hole of pin positioning sleeve 3 is the pin hole that cooperates with pin 2, and the internal conical surface 10 that cooperates with pin 2 front ends is arranged in the pin hole.In the installing hole 8 of pin positioning sleeve 3 belows spring leaf 4 is housed, lower bolster 1 sidewall is equipped with the lock-screw 5 to pin positioning sleeve 3 axial location.
During assembling, spring leaf 4 is put into the installing hole 8 of lower bolster 1, put into pin positioning sleeve 3 again, push down pin positioning sleeve 3 with finger, make on the pin positioning sleeve plane concordant or a little less than plane on the template, screw in lock-screw 5 again, screw 5 front ends are pressed on pin positioning sleeve 3 on installing hole 8 walls; The pin 2 of cope match-plate pattern 6 is put into pin positioning sleeve 3, two templates are just located, press down cope match-plate pattern 6 then, cooperate by taper seat to make two templates location eventually.During the dismounting of pin positioning sleeve, as long as unclamp lock-screw, spring leaf will discharge elastic potential energy, ejects the pin positioning sleeve, realizes changing.
The utility model is suitable equally to non-plastics extrusion die, can adopt this kind localization method to obtain by changing the form of pin and pin positioning sleeve.
