Fig. 1-6 show the side direction loose core mould with accurate locking mechanism of a preferred embodiment of the utility model, including cover half 1 and 2 of loosing core, loose core 2 can remove along the horizontal direction for cover half 1 to the closing cap cover half 1 or open cover half 1.

The fixed mold 1 is fixed with a female seat 11, and the female seat 11 has a first front and rear thrust surface 111, a first upper and lower thrust surface 112, and a first left and right thrust surface 113.

The core back 2 is fixed to a male seat 21, and the male seat 21 has a second front and rear thrust surface 211, a second upper and lower thrust surface 212, and a second left and right thrust surface 213.

The first front and rear thrust surfaces 111 are adapted to abut the second front and rear thrust surfaces 211.

The first upper and lower thrust surfaces 112 are adapted to abut the second upper and lower thrust surfaces 212.

The first left and right thrust surfaces 113 are adapted to abut the second left and right thrust surfaces 213.

All the spatial degrees of freedom (i.e. 6 spatial degrees of freedom including movement and rotation, i.e. fully defined) can be mutually defined by the female seat 11 and the male seat 21 by means of mutual abutment and interference of two of the six thrust surfaces.

When the mould closing mechanism works, the core pulling 2 can still be driven by the oil cylinder (or other conventional driving mechanisms) to move close to or away from the fixed mould 1, so that mould closing or mould opening is realized. As for how to drive the loose core 2 to move and how to guide the loose core 2, since the prior art is mature, this is only for example, but not repeated. For example: the driving mode can be through hydro-cylinder, motor and lead screw combination, gear and rack combination etc.. The guiding mode can be realized by simple matching of the guide rail and the sliding block, matching of the roller and the guide rail, matching of the guide column and the guide hole and the like.

Set up like this, when pushing away through the hydro-cylinder and loosing core 2 and fixed mould 1 cooperation, though the thrust of source can not aim the focus of loosing core 2 accurately, probably still make 2 of loosing core produce various offsets in the translation process that is close to fixed mould 1. But through the matching of the male seat 21 and the female seat 11, the connection part of the loose core 2 and the fixed mold 1 can be accurately matched, so that errors caused by a series of previous processes can be thoroughly corrected, the connection part of the fixed mold 1 and the loose core 2 can be accurately matched, the flash degree of a product is reduced, the continuous work of the mold is ensured, and the product quality and the production efficiency are greatly improved. That is, no matter how many errors are accumulated in the process of pushing the core pulling 2 by the oil cylinder, and no matter how high the temperature of the core pulling 2 increases the errors, after the male seat 21 is matched with the female seat 11, all the errors are equalized to be zero (or close to zero), so that the problems that the product has serious flash and the mold cannot work continuously in the prior art can be thoroughly solved.

The first front and rear thrust surface 111, the first upper and lower thrust surfaces 112, and the first left and right thrust surfaces 113 may be perpendicular or nearly perpendicular to each other, as long as they can fully define the three XYZ directions. However, obviously, for the convenience of positioning and separation, the included angle a between the first front and rear thrust surfaces 111 and the first upper and lower thrust surfaces 112 should be greater than 90 °; and the included angle B between the first front and rear thrust surfaces 111 and the first left and right thrust surfaces 113 should be greater than 90 DEG

Similarly, the second front and rear thrust surfaces 211, the second upper and lower thrust surfaces 212, and the second left and right thrust surfaces 213 may be perpendicular or close to perpendicular to each other, as long as the complete definition of the three XYZ directions can be achieved. However, it is obvious that the angle C between the second front and rear thrust surfaces 211 and the second upper and lower thrust surfaces 212 should be greater than 90 ° for easy positioning and separation; the included angle D between the second front and rear thrust surfaces 211 and the second left and right thrust surfaces 213 should be greater than 90 °.

Obviously, the rectangular hole facilitates reliable and convenient XYZ direction definition. That is, other polygonal hole locations are sufficient to accomplish the fixed relationship.

Further, the male seat 21 is provided with a second mounting hole on the second front and rear thrust surfaces 211 along a direction perpendicular to the second front and rear thrust surfaces 211, a second fastening member 25 is inserted into the second mounting hole, and the second fastening member 25 is used for fixing the male seat 21 on the fixed die 1. Obviously, the second fastener 25 may be a conventional screw, bolt, jackscrew, or the like.

Furthermore, one of the fixed mold 1 and the loose core 2 is provided with a limiting hole 26, the part of the male seat 21, which is abutted against the female seat 11, is located in the limiting hole 26, and the limiting hole 26 limits the male seat 21 or the female seat 11. Set up like this for when hydro-cylinder (or other conventional actuating mechanism) promoted 2 contacts cover half 1 of loosing core, through the surrounding and spacing of spacing hole 26, can make public seat 21 closely laminate with female seat 11, thereby guarantee the locking effect, thereby further improve the processingquality of product, and guarantee the work continuity of mould.
