Abstract
The utility model discloses a core-pulling structure for a first reset mechanism of a sliding block ejector pin. The core-pulling structure consists of an inclined guide post (1), a sliding block locking block (2), a sliding block (3), a sliding blocking insert pin (4), a spring (5) and a sliding block insert pin limiting block (6), wherein the sliding block insert pin (4), the spring (5) and the sliding block insert pin limiting block (6) are arranged in the sliding block (3); the core-pulling structure is characterized in that the sliding block insert pin (4) is sleeved with the spring (5) and is limited in the sliding block (3) through the sliding block insert pin limiting block (6); the tail surface of the sliding block insert pin (4) is higher than the surface of the sliding block insert pin limiting block (6). The core-pulling structure is simple; the sliding block cannot be damaged by a mold core insert when mold closing is performed, and a product cannot be adhered to the sliding block when the mold opening is performed, so that the mold is stripped easily.
Description
Technical field
The utility model relates to injection mold structure, particularly relates to the structure that the first resetting-mechanism of a kind of slide block thimble is loosed core.
Background technology
Automobile lamp is one of main accessory of automobile, and along with the development of automotive engineering, people have proposed more and more higher requirement to the Design and manufacture of automobile lamp.As automobile front fog lamp, mainly by lamp housing, reverberation bowl, lens and bulb, formed.The present product structure for envelope inner wall patterned wall through hole, normally adopt slide block directly to loose core, the pulled core structure being formed by Angle Pin, shovel chicken and three parts of slide block, although this structure handling ease, but the post core when matched moulds on slide block is easily wounded by die mold insert, and product is easily wrapped on slide block post core during die sinking, product be easily out of shape and break, drawing crack etc.
Summary of the invention
For above-mentioned defect, the purpose of this utility model is to provide a kind of slide block thimble structure that first resetting-mechanism is loosed core, and by Angle Pin, makes slide block separated with shovel chicken or merge, and is provided with slide block pin, spring and slide block pin limited block in slide block; When slide block merges with shovel chicken, shovel chicken jacking sliding piece pin ejects slide block pin under the effect of spring; When slide block is with shovel chicken when separated, has resetted under the effect of the spring work of loosing core in hole of slide block pin, while both having guaranteed matched moulds, slide block can not wounded by die mold insert, and while having guaranteed die sinking again, product can not be bonded on slide block, the easy demoulding.
The technical solution adopted in the utility model is: the structure that the first resetting-mechanism of a kind of slide block thimble is loosed core, by Angle Pin, shovel chicken, slide block, slide block pin, spring, slide block pin limited block, formed, in described slide block, be provided with slide block pin, spring and slide block pin limited block, it is characterized in that: on described described slide block pin, cover has spring and is limited in slide block by slide block pin limited block, and slide block pin afterbody face exceeds slide block pin limited block face.
Described slide block matched moulds, slide block drives with shovel chicken and merges at Angle Pin, and shovel chicken jacking sliding piece pin ejects slide block pin under the effect of spring.
Described slide block die sinking, slide block is separated with shovel chicken under Angle Pin drives, slide block pin the loosing core of hole that resetted under the effect of spring, slide block continues to retreat under Angle Pin driving, completes all and looses core.
The utility model, simple in structure, while both having guaranteed matched moulds, slide block can not wounded by die mold insert, and while having guaranteed die sinking again, product can not be bonded on slide block, the easily demoulding.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model when die sinking.
Fig. 2 is the structural representation of the utility model when matched moulds.
Fig. 3 is the respective outer side edges schematic diagram of the utility model and die mold insert.
In figure: 1 is that Angle Pin, 2 is for shovel chicken, 3 is for slide block, 4 is for slide block pin, 5 is for spring, 6 is for slide block pin limited block, 7 is for die mold insert, 8 is for lamp housing plastic.
The specific embodiment
By Fig. 1, Fig. 2, Fig. 3, known, the structure that the first resetting-mechanism of a kind of slide block thimble is loosed core, by Angle Pin 1, shovel chicken 2, slide block 3, slide block pin 4, spring 5, slide block pin limited block 6, formed, the interior installation slide block of slide block 3 pin 4 and spring 5, on shovel chicken 2, slide block pin limited block 6 is installed, after when matched moulds, slide block 3 merges with shovel chicken 2 under Angle Pin 1 drives, shovel chicken 2 jacking sliding piece pin 4 afterbodys, eject with die mold insert 7 slide block pin 4 top under the effect of spring 5 and coordinate; During die sinking, slide block 3 is separated with shovel chicken 2 under Angle Pin 1 drives, resetted under the effect of spring 5 work of loosing core in hole of slide block pin 4, slide block 3 continues to retreat under Angle Pin 1 drives until complete all and loose core, so far complete the production of one-period, while both having guaranteed matched moulds, slide block 3 can not wounded by die mold insert 7, while having guaranteed die sinking again, lamp housing plastic 8 can not be bonded on slide block 3, the easily demoulding.
