Abstract
The invention provides a coring structure with an inverted buckle in the coring direction of a slide block, which can be used for forming a product with the inverted buckle in the coring direction of the slide block in one step and has the advantages of time and labor saving and high processing efficiency. The coring structure comprises the slide block and a locking block which is connected with the slide block, and is characterized in that the inverted buckle part of the product to be processed is provided with an oblique top insert,, the outer side of which is matched with the inverted buckle part; the inner side of the oblique top insert is communicated with a contractive bevel in the center of the product; a convex block which extends outwards is installed at the inner side of the oblique top insert; the outer side of the slide block is a bevel; a guide rail is embedded into the outer side of the slide block; and the convex block is embedded into the guide rail.
Description
Technical field
The present invention relates to the technical field of structures of loosing core of injection mold, be specially the slide block direction of loosing core and have the structure of loosing core of back-off.
Background technology
Existingly have the product of back-off in the slide block direction of loosing core, it can not take off by force, after need machining, carries out secondary operations in its back-off position again, thereby finishes the manufacturing of product, and it is wasted time and energy, and working (machining) efficiency is low.
Summary of the invention
At the problems referred to above, the invention provides the slide block direction of loosing core and have the structure of loosing core of back-off, it can make the slide block direction of loosing core have the product one-shot forming of back-off, and is time saving and energy saving, and the working (machining) efficiency height.
The slide block direction of loosing core has the structure of loosing core of back-off, its technical scheme is such: it comprises slide block, latch segment, described slide block connects described latch segment, it is characterized in that: the back-off of product corresponding to be processed partly is provided with the oblique top mold insert, the outside of described oblique top mold insert cooperates described back-off part, the inclined-plane that product center is shunk is led in the inboard of described oblique top mold insert, the installed inside of described oblique top mold insert has the projection of evagination, the described slide block outside is the inclined-plane, the outside of described slide block is embedded with guide rail, the nested described guide rail inside that is loaded on of described projection.
It is further characterized in that: a side of the close oblique top mold insert of described projection is less than a described side away from the oblique top mold insert, and described oblique top mold insert engage sleeves is loaded on described guide rail inside.
After adopting said structure of the present invention, latch segment drives slide block to moving away from the line of production, the obstruction that the oblique top mold insert keeps being subjected to product back-off part can't be followed slide block and be moved together, guide rail and projection produce relative motion, make guide rail inwardly shrink, driving the oblique top mold insert inwardly shrinks, partly finish until the outside of oblique top mold insert and back-off and to loose core, the oblique top mold insert is finished integral body together and is loosed core along with slide block afterwards, it can make the slide block direction of loosing core have the product one-shot forming of back-off, time saving and energy saving, and the working (machining) efficiency height.
Description of drawings
Fig. 1 is a vertical view structural representation of the present invention;
Fig. 2 is the partial enlarged drawing at A place;
Fig. 3 is the three-dimensional structure schematic diagram of oblique top mold insert of the present invention and slide block.
The specific embodiment
See Fig. 1, Fig. 2, Fig. 3, the present invention includes slide block 2, latch segment 3, slide block 2 connects latch segment 3,1 for having the product of back-off, the back-off part 4 of product 1 is equipped with oblique top mold insert 5, the outside of oblique top mold insert 5 cooperates back-off part 4, the inclined-plane that shrink at product 1 center is led in the inboard of oblique top mold insert 5, the installed inside of oblique top mold insert 5 has the projection 6 of evagination, slide block 2 outsides are the inclined-plane, the outside of slide block 2 is embedded with guide rail 7, and a side of projection 6 close oblique top mold inserts 5 is less than the side away from oblique top mold insert 5, and oblique top mold insert 5 engage sleeves are loaded on guide rail 7 inside.
Claims (2)
1. the slide block direction of loosing core has the structure of loosing core of back-off, it comprises slide block, latch segment, described slide block connects described latch segment, it is characterized in that: the back-off of product corresponding to be processed partly is provided with the oblique top mold insert, the outside of described oblique top mold insert cooperates described back-off part, the inclined-plane that product center is shunk is led in the inboard of described oblique top mold insert, the installed inside of described oblique top mold insert has the projection of evagination, the described slide block outside is the inclined-plane, the outside of described slide block is embedded with guide rail, the nested described guide rail inside that is loaded on of described projection.
2. the slide block according to claim 1 direction of loosing core has the structure of loosing core of back-off, it is characterized in that: less than a described side away from the oblique top mold insert, described oblique top mold insert engage sleeves is loaded on described guide rail inside to described projection near a side of oblique top mold insert.
