Abstract
The utility model discloses an inwards-contracting rear mold slide structure which comprises a rear mold plate, a rear mold core and a push plate that is positioned below the rear mold plate and can perform vertical motion relative to the rear mold plate; a shovel base which can slide up and down in the rear mold plate and the rear mold core is fixedly mounted on the push plate; a matching inclined surface is arranged at the side end of the shovel base; an inwards-contracting slide passing through the rear mold plate and the rear mold core is embedded on the matching inclined surface; the bottom of the inwards-contracting slide is embedded on the rear mold plate through the sliding of a sliding block; a slide insert core embedded into a product is arranged at the top of the inwards-contracting slide. According to the structure, before the parting of a front mold core and the rear mold core, the push plate drives the shovel base to move downwards and vertically relative to the rear mold plate, so as to drive the inwards-contracting slide to move in the sliding direction of the sliding block, therefore, the slide insert core is enabled to contract automatically and get out of a button position on the product. The structure has the advantages that a high-precision inclined hole matched with an inclined top is not required to be processed in the rear mold, so the processing difficulty is reduced, the sliding of the inwards-contracting slide is more smooth, the situation that products stick on the mold is prevented, meanwhile, the intensity of the inwards-contracting slide is improved, and the service life is prolonged.
Description
Technical field
The utility model relates to mould applications, particularly a kind of internal withdraw type rear mold line position structure.
Background technology
In plastic cement products, often can run into can not vertical-parting depanning structure as button bit, side opening etc., now need the auxiliary somatotype depanning of line position mechanism of designing mould, but existing mould line position mechanism generally adopts ramp-roof structure, it mainly comprises oblique top, oblique top is positioned in the inclined hole of a fixed template, in the time of the mould vertical-parting of mould front and back, oblique top is applied to power vertically upward, oblique top is under the restriction and guide effect of inclined hole, oblique top both moved both vertically, (resultant motion is oblique movement) moves horizontally again, thereby make the oblique top that is arranged at oblique top end enter son disengaging button bit etc., because said structure is mainly by oblique top and is arranged at the inclined hole cooperation realization front and back mould somatotype in template, its requirement on machining accuracy is high, inclined hole difficulty of processing is large, easily cause oblique top motion not smooth and stuck, simultaneously because oblique top both moved both vertically product is ejected to die, move horizontally again and make oblique top enter son to deviate from button bit etc., because the angle of inclination of oblique top can not be too large, while many times having pushed up from die in product upper end, but oblique top enters son and does not also deviate from button bit, if now oblique top continues motion, easily produce product mold sticking, cause product to pull, in addition, this structure is because oblique top need to eject oblique product, oblique top length is long, oblique top intensity difference, easily cause oblique top to enter son distortion.
Utility model content
In order to overcome the deficiencies in the prior art, the internal withdraw type rear mold line position structure that the utility model provides a kind of handling ease, moves smooth and easy, product is difficult for sticking to mould.
The utility model solves the technical scheme that its technical problem adopts:
A kind of internal withdraw type rear mold line position structure, comprise rear pattern plate, be assemblied in the rear cavity of rear pattern plate upper end and be positioned under rear pattern plate can its work moves both vertically relatively push pedal, described push pedal is installed with the shovel base that can slide up and down in rear pattern plate and rear cavity, shovel base side is provided with a cooperation inclined-plane, on this cooperation inclined-plane, slide and be embedded with the line position that inside contracts through rear pattern plate and rear cavity, slided and be flush-mounted on rear pattern plate by slide block in the bottom that inside contracts line position, the line position that the top that inside contracts line position is provided with embedded product enters son, described push pedal drives shovel base to move vertically downward with respect to rear pattern plate and orders about and inside contract line position and move and deviate from product so that line position enters son along slide block glide direction.
As the improvement of technique scheme, on the cooperation inclined-plane of described shovel base, be provided with T-shaped guide rail, described in inside contract line position near coordinating the side on inclined-plane to offer the T-shaped chute being slidably matched with T-shaped guide rail.
Further, described line position enters son and to inside contract line position one-body molded, described in inside contract line position bottom and slide block be bolted to connection.
Further, described in inside contract line position and slide block is rectangular configuration, and be fixedly connected with rear formation with slide block L shaped in the bottom that inside contracts line position.
Further, described upper end of slide block is provided with to peg graft and inside contracts the slot of line position, the described side that inside contracts line position and slide block is provided with the fastener hole for being fixedly connected with, and inside contracts line position and inserts after slot, is tightened against and in fastener hole, will inside contracts line position and slide block is fixed with fastening bolt.
Further, the bottom that inside contracts line position and slide block described in all offers for the locking hole of clamping screw to prevent that fastening bolt is loosening is installed.
Further, described slide block is convex shape, offers the mounting groove of slip setting-in slide block on described rear pattern plate, and the both sides of mounting groove are provided with to be fixedly installed in and slide block are limited in to the pressing plate sliding in mounting groove on rear pattern plate.
Further, between described shovel base and push pedal, adopt bolt to be fixedly connected with.
The beneficial effects of the utility model are: the utility model is before the die somatotype of front and back, push pedal and be fixedly installed in the relative rear cavity of shovel base in push pedal, rear pattern plate moves both vertically downwards, now, the shovel internal indention of base position produces pulling force vertically downward, be flush-mounted on the cooperation inclined-plane of shovel base owing to inside contracting line position slip, slided and be flush-mounted on rear pattern plate by slide block in the bottom that simultaneously inside contracts line position, therefore, shovel base drives while moving downward vertically with respect to rear pattern plate and inside contracts line position and move along the glide direction of slide block, thereby make to be arranged at the line position that inside contracts line position top enter son can automatic retraction and depart from button bit or the side opening of product.This structure is without coordinating with oblique top at the high inclined hole of the inner machining accuracy of rear cavity, greatly reduce difficulty of processing, and the slip that inside contracts line position is more smooth and easy, prevent product sticking to mould, inside contract line position length shorter simultaneously, intensity is high, and it is not yielding that line position enters son, has extended the service life of line position structure.
