Abstract
The invention discloses a slide block demolding mechanism, and belongs to the field of demolding apparatuses in mold processing. The slide block demolding mechanism comprises an upper template, a lower template, a slide block, a slide block seat, a shovel base, a positioning seat, a hexagonal socket head cap screw, springs, two horizontal guiding briquettes, pins and two inclined guiding briquettes, the slide block, the slide block seat and the positioning seat are arranged between the cavity of the upper template and the cavity of the lower template, the slide block seat is provided with an inclined T-shaped chute, the slide block is correspondingly provided with an inclined slide projection, the slide block seat is movably connected with the slide block through the cooperation of the inclined T-shaped chute and the inclined slide projection, the two horizontal guiding briquettes and the two inclined guiding briquettes are symmetrically arranged at two sides of the slide block and the slide block seat and are fixed on the lower template through the pins, and the shovel base is arranged in the slot of the slide block seat. The shovel base releases locking force on the slide block under the action of a mold opening machine of an injection machine in order to make the slide block and the slide block seat rapidly slide away from a product under the driving of the reset force of the springs in order to make the product nondestructively demolded.
Description
Technical field
The present invention relates to the demoulding device field in Mould Machining, particularly a kind of slide block demolding mechanism.
Background technology
In the process of injection mold, a lot of products have back-off in cover half direction, the normally demoulding and ejecting product, need to make in addition the demoulding of angled-lift splits ability, in the time that the rib of product is darker, product easily and slide block cling, cause the product can not die sinking, even pull product, stripping result is undesirable.In prior art, also there is the stripper apparatus that adopts angled-lift splits, if the patent No. is " fastener lifter mechanism of automobile steering lamp mold " of " 201020262071.6 ", but in knockout course, adopt injection machine power to drive push rod, jacking block, oblique slide bar, angled-lift splits, make angled-lift splits and buckle throw off the demoulding, structure is more complicated, and processing cost is higher.
Summary of the invention
Main purpose of the present invention is to provide a kind of slide block demolding mechanism that utilizes the reset stress of spring to realize depanning, simple in structure, cuts down finished cost.
The present invention includes cope match-plate pattern, lower bolster, slide block, take-up housing, shovel base, positioning seat, hexagonal socket head cap screw, spring, two horizontally-guided briquettings, pin, two oblique guiding briquettings, described slide block, take-up housing, positioning seat is placed between cope match-plate pattern and the die cavity of lower bolster, described take-up housing is provided with oblique T chute, on described slide block, be correspondingly provided with oblique sliding projection, described take-up housing is flexibly connected with the cooperation of tiltedly sliding projection by oblique T chute with slide block, described two horizontally-guided briquettings, two oblique guiding briquettings are listed in symmetrically described slide block and take-up housing both sides and are fixed by a pin on lower bolster, shovel base one end is fixed on cope match-plate pattern, the other end is placed in the hole slot of take-up housing.
Preferably, described positioning seat is provided with screw, described positioning seat is fixedly connected with take-up housing by a cup screw, a described cup screw suit spring and is sunk to and be arranged in described screw, described spring before die sinking in confined state, described spring one end is being tight against the nut of hexagonal socket head cap screw, and the other end is being tight against the bottom surface of screw.
Described slide block is rhomboid, and afterbody has the oblique T groove of guiding.
Lower bolster relevant position, middle part and described take-up housing are separated by a distance, form and make slide block slide to smoothly the empty avoiding chamber of lowest order.
Beneficial effect of the present invention is: in the time that shovel base is removed the sealed power to take-up housing under injection moulding machine mould open mechanism, slide block and the take-up housing product that slips away rapidly under the reset force of spring drives, can not pull product, makes the light and not damaged demoulding of product; Horizontally-guided briquetting and the guide effect of briquetting to slide block of tiltedly leading, more smooth, steady when it is slided; The oblique T groove of guiding of slider tail is conducive to slide block and departs from product.
Accompanying drawing explanation
Fig. 1 is the three-dimensional structure diagram of slide block demolding mechanism of the present invention;
Fig. 2 is the sectional structure chart of slide block demolding mechanism of the present invention;
The object of the invention realization, functional characteristics and advantage, in connection with embodiment, are described further with reference to accompanying drawing.
The specific embodiment
Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
With reference to Fig. 1, Fig. 2, one embodiment of the invention is proposed, the present embodiment comprises cope match-plate pattern A, lower bolster B, slide block 1, take-up housing 2, shovel base 3, positioning seat 4, hexagonal socket head cap screw 5, spring 6, two horizontally-guided briquettings 7, pin 8, two oblique guiding briquettings 9, described slide block 1, take-up housing 2, positioning seat 4 is placed between cope match-plate pattern A and the die cavity of lower bolster B, described take-up housing 2 is provided with oblique T chute, on described slide block 1, be correspondingly provided with oblique sliding projection, described take-up housing 2 is flexibly connected with the cooperation of tiltedly sliding projection by described oblique T chute with slide block 1, described two horizontally-guided briquettings 7, two oblique guiding briquettings 9 are listed in symmetrically described slide block 1 and take-up housing 2 both sides and are fixed on lower bolster B by pin 8, shovel base 3 one end are fixed on cope match-plate pattern A, the other end is placed in the hole slot of take-up housing 2.
Preferably, described positioning seat 4 is provided with screw 11, described positioning seat 4 is fixedly connected with take-up housing 2 by a cup screw 5, described hexagonal socket head cap screw 5 is being set with spring 6 and is sinking to and be arranged in described screw 11, described spring 6 before die sinking in confined state, described spring 6 one end are being tight against the nut 12 of hexagonal socket head cap screw 5, and the other end is being tight against the bottom surface of screw 11.
Described slide block 1 is rhomboid, and afterbody has the oblique T groove 13 of guiding.
Relevant position, described lower bolster B middle part is separated by a distance from described take-up housing 2, forms and makes slide block 1 slide to smoothly the empty avoiding chamber of lowest order.
When die sinking, the cope match-plate pattern A of injection machine lifts, the shovel base 3 being fixed on cope match-plate pattern A lifts disengaging hole slot thereupon, thereby remove the sealed power to take-up housing 2, under the reset screen resilience effect of spring, spring stretches to nut 12 directions of a cup screw, and being fixed on injection machine, positioning seat keeps motionless with it, hexagonal socket head cap screw 5 moves to nut 12 directions under the drive of spring, thereby drive take-up housing 2, and then the direction of the oblique T chute in oblique guiding briquetting 9 and take-up housing 2 is sunk toward lower bolster B with movable slider 1, then together move toward nut 12 directions along horizontally-guided briquetting 7 with take-up housing 2, the oblique T groove 13 of guiding of 10 of the products of moulding from slide block 1 afterbody, depart from, thereby complete the demoulding.
The foregoing is only the preferred embodiments of the present invention; not thereby limit the scope of the claims of the present invention; every equivalent structure transformation that utilizes description of the present invention and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
