Abstract
The utility model relates to a core-pulling structure which is frequently used on a mould, in particular to a mould counter core-pulling structure. The mould counter core-pulling structure comprises a pulling core and a counter pulling core. The mould counter core-pulling structure is characterized in that a groove structure is formed in the front end of the pulling core, and a protrusion structure matched with the groove structure is correspondingly arranged at the front end of the counter pulling core. Accordingly, the mould counter core-pulling structure is reasonable in design, practical and convenient to use.
Description
(1) technical field
The utility model relates on a kind of mould core-pulling mechanism commonly used, particularly a kind of mould to pulled core structure.
(2) background technology
At present, the range of application of cast member is more and more extensive, and is along with complexity, the measure of precision of cast member are more and more higher, therefore also more and more stricter to designing requirement, the processing request of mould.Thereby the mould of pulled core structure uses also more and more general in Design of Dies, the product of original many deep-hole structures also gradually by rear machining, adjust to the mould core pulling depanning, yet there is drawback in existing structure, the one, if adopt the one direction pulled core structure, the machining accuracy of loosing core is difficult to reach, and affected by the die cavity fluid challenge, size is more difficult stable, the 2nd, if adopt independently, to pulled core structure, be easy to produce wrong chamber, two kinds of modes all greatly reduce the precision of product fit dimension.
(3) summary of the invention
The utility model is in order to make up the deficiencies in the prior art, provides mould a kind of reasonable in design, simple in structure to pulled core structure.
The utility model is achieved by the following technical solution:
A kind of mould to pulled core structure, comprise loose core, to loosing core, it is characterized in that: the described front end of loosing core is provided with groove structure, accordingly the front end of loosing core is provided with to the bulge-structure suitable with groove structure.
Described groove structure is topmost cylindric, and middle part is the cone-shaped that external diameter diminishes gradually, and low side is the spherical crown shape; Described the bulge-structure of loosing core is pushed up as spherical crown shape, middle part are that external diameter becomes large cone-shaped gradually most, tail end is cylindric.
The utility model has changed the product that in the past needs long pulled core structure, adopt one direction to loose core or adopt the independent drawback that pulled core structure is existed, solve the product fit dimension precision that traditional structure causes and do not reached the shortcoming of requirement, reasonably utilize taking out structure, make to loose core and no longer work alone to loosing core, but be used in conjunction with, greatly improved the precision of the portion structure of loosing core.
The utility model is simple in structure, behavior is reliable, and process is simple, be suitable for need to longer pulled core structure product, can greatly improve the precision at the position of loosing core, effectively guarantee product quality, be suitable for wide popularization and application.
(4) accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
Accompanying drawing 1 is structural representation of the present utility model;
In figure, 1 looses core, loose core for 2 pairs, and 3 groove structures, 4 bulge-structures.
(5) specific embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.This embodiment comprise loose core 1, to loosing core 2, it is characterized in that: described 1 front end of loosing core is provided with groove structure 3, accordingly 2 front ends of loosing core is provided with to the bulge-structure 4 suitable with groove structure 3; Described groove structure 3 is topmost cylindric, and middle part is the cone-shaped that external diameter diminishes gradually, and low side is the spherical crown shape; Described 2 bulge-structures of loosing core are pushed up as spherical crown shape, middle part are that external diameter becomes large cone-shaped gradually most, tail end is cylindric.
Described loosing core on 1 is designed with groove structure 3, groove structure 3 bottoms be R type groove (being spherical crown shape part), middle part for angled climbing structure (being the cone-shaped part), topmost be designed with >=linear structure (being cylindric part) of 3mm.
Described correspondence to loosing core on 2, be designed with bulge-structure 4, bulge-structure 4 outermost end be R type structure (being spherical crown shape part), middle part for angled climbing structure (being the cone-shaped part), topmost be designed with >=linear structure (being cylindric part) of 3mm, and size is consistent with 1 cooperation of loosing core.
adopt mould of the present utility model to pulled core structure, loose core in mould matched moulds process 1 groove structure 3 and corresponding 2 bulge-structures 4 of loosing core are coordinated, at first be that the 2 protruding R type structures of loosing core are entered to 1 groove structure 3 inside of loosing core, be designed to R type structure and be the shortcoming that meat or horn structure are are very easily worn and torn that collapses while avoiding right-angle structure to cause micro-wrong chamber, then be the routing motion process to loose core 2 middle part climbing structures and the 1 middle part climbing structure of loosing core, make two pairs of being combined slowly of loosing core, played guide effect, it is finally the routing motion process to linear structure with the linear structure of the 1 >=3mm of loosing core of the 2 >=3mm of loosing core, last this process makes pulled core structure coordinate fully closely, this structure has also played firmly, the effect of location.Although simple in structure, this structure has been divided into syllogic by whole matched moulds process, rational in infrastructure, behavior is reliable, can greatly improve the precision at the position of loosing core, and effectively guarantees product quality.
Claims (3)
1. a mould to pulled core structure, comprise loose core (1), to loose core (2), it is characterized in that: described loosing core (1) front end is provided with groove structure (3), accordingly (2) front end of loosing core is provided with to the bulge-structure (4) suitable with groove structure (3).
Mould according to claim 1 to pulled core structure, it is characterized in that: described groove structure (3) is topmost for cylindric, and middle part is the cone-shaped that external diameter diminishes gradually, and low side is the spherical crown shape.
