Abstract
A kind of T-shaped shrinks core fixture for processing, comprises interior core, centring sleeve, contour pad and pressing plate; Centring sleeve has the flat surface that is used for carrying interior core, and this surface is convexly equipped with one for locating the locating dowel of interior core, and interior core is arranged on centring sleeve by locating dowel location; Contour pad is set on interior core, and contour pad and the parallel and interval of centring sleeve are arranged, contour pad and centring sleeve affixed so that the bottom of interior core is fixed; The T-slot corresponding position of contour pad and interior core is provided with the pressing plate shrinking core for fixing T-shaped.The mode that the utility model adopts the interior core of intending the cooperation of T-shaped contraction core to match with fixture is fixed T-shaped and is shunk core, so that carry out the processing that T-shaped shrinks core, stability maintenance and machining accuracy that T-shaped shrinks core are effectively heightened, thus effectively heightened the machining accuracy of mould matching part and the organoleptic quality of product, substantially increase the mold use life-span.
Description
Technical field
The utility model relates to a kind of T-shaped and shrinks core fixture for processing, the forming part fixture for processing of particularly a kind of radial demoulding for multi-cavity bottle cap class precise injection mould internal thread or interior buckle.
Background technology
Traditional multi-cavity bottle cap class injection mold generally adopts forced stripper mechanism mode for internal thread or the more shallow person of interior buckle radial depth, and its remarkable defect is that mould easily pulls product and forming part in knockout course, causes product quality and die life all lower.Generally adopt HALF block stripping means for internal thread or the darker person of interior buckle radial depth, mould structure is comparatively complicated, and die manufacturing cost is higher.
In recent years, a lot of Mould Enterprise is the mould structure simplifying the type product, successfully develop the mould structure that T-shaped shrinks core and elastic shrinkage core, but elastic shrinkage core is because requiring higher to the elastic performance of material, current domestic associated heat treatment technics does not break through always and makes it to reach requirement, therefore its stability in use is poor, increasing Mould Enterprise have employed the mould structure that band T-shaped shrinks core.T-shaped in this mould structure is shunk core and (is had another name called: angled-lift splits belongs to slender rod type part, the T-slot that its T-shaped band shoulders is corresponding with on interior core under mold releasability and matched moulds state coordinates, mould is in shaping position both when injection mo(u)lding, the internal thread of bottle cap series products or the shaping position design of interior buckle are on T-shaped slide block, the outer cone arc surface that outer cone arc surface must be mated the parent (namely in core) of assembling coincide consistent after coordinate sealing with band with the throw-out collar of angle taper hole simultaneously, its requirement on machining accuracy is height very as seen.Single-piece T-shaped shrink core fixture for processing independently add man-hour not only machining deformation large and in process inconvenient clamping and centering, be difficult to its machining accuracy of guarantee and reach design and use requirement.
Summary of the invention
The utility model provides a kind of T-shaped to shrink core fixture for processing.
For achieving the above object, the technical solution adopted in the utility model is: a kind of T-shaped shrinks core fixture for processing, comprises interior core, centring sleeve, contour pad and pressing plate; Described centring sleeve has the flat surface that is used for carrying described interior core, and this surface is convexly equipped with one for locating the locating dowel of described interior core, and described interior core is arranged on centring sleeve by locating dowel location; Described contour pad is set on described interior core, and described contour pad and the parallel and interval of centring sleeve are arranged, described contour pad and centring sleeve affixed so that the bottom of described interior core is fixed; The T-slot corresponding position of described contour pad and interior core is provided with the pressing plate shrinking core for fixing T-shaped.
Preferred technical scheme is: described locating dowel is cylinder, and the corresponding described cylinder in bottom of described interior core is provided with the recess of form fit.
Preferred technical scheme is: described flat surface is for circular, and described locating dowel is located at circular center.
Preferred technical scheme is: described interior core has one section of cylindrical section, and the center of described contour pad offers manhole, and this through hole coordinates with described cylindrical section.
Preferred technical scheme is: it is affixed that described contour pad and centring sleeve pass through bolt.
Because technique scheme is used, the utility model compared with prior art has following advantages:
The mode that the utility model adopts the interior core of intending the cooperation of T-shaped contraction core to match with fixture is fixed T-shaped and is shunk core, so that carry out the processing that T-shaped shrinks core, stability maintenance and machining accuracy that T-shaped shrinks core are effectively heightened, thus effectively heightened the machining accuracy of mould matching part and the organoleptic quality of product, substantially increase the mold use life-span.
