Abstract
A sliding block and lifter combination demoulding mechanism for an injection mold comprises an upper plate and a lower plate of the mold, wherein the upper plate is connected with a solid plate through a cushion block, the lower plate is provided with a supporting block, the supporting block is internally provided with an ejector plate, an ejector pin is connected onto the ejector plate, the supporting block is provided with a movable plate, a shaped plastic product is positioned between the movable plate and the solid plate, a fastener is manufactured on the plastic product, a location hole is manufactured in the fastener, and an under cut is formed between the fastener and a product body. The mechanism is characterized in that one side of the movable plate is slidably provided with a sliding block, the inner side of the sliding block is connected with a location hole core which is matched with the location hole, the sliding block is internally provided with a lifter hole, a lifter pillar is connected to the lower part of the solid plate, and the lifter pillar and the lifter hole are mutually matched; a sliding seat is arranged on the ejector plate and is internally provided with a chute, the chute is connected with a lifter rod, and the head part of the lifter rod is matched with the under cut. In the scheme, the demoulding of the location hole adopts a way that the lifter pillar drives the sliding block to smoothly pull the core, the demoulding of the under cut adopts a lifter way, and the two ways are mutually combined and matched, so that the product can be demoulded and ejected successfully.
Description
Technical field
The utility model relates to a kind of injection mold slide block oblique top combination mould emptier, belongs to the mould of plastics field.
Background technology
Adopt injection mold to produce plastic product, inner chamber of car working of plastics for example, in order to make working of plastics easy for installation and firm, on working of plastics, be shaped on buckle, be shaped on locating hole in the buckle, form back-off between buckle and the working of plastics body, therefore, when product ejects, after needing respectively locating hole and back-off carried out the demoulding, product could be ejected outside the mould demoulding difficulty.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming of prior art, provides a kind of slide block smoothly to loose core tiltedly to slide with oblique top to eject combination and cooperates, makes the injection mold slide block oblique top of the smooth demoulding of product make up mould emptier.
The technical scheme of the utility model injection mold slide block oblique top combination mould emptier is: comprise upper mould plate and lower bolster, cope match-plate pattern connects solid plate through cushion block, the mould pin is installed on the lower bolster, in the mould pin top board is set, connect push rod on the top board, on the mould pin moving platen is installed, the plastic product that moulding is arranged between moving platen and the solid plate, be shaped on buckle on the plastic product, be shaped on locating hole in the buckle, form back-off between buckle and the product body, it is characterized in that described moving platen one side slip is provided with slide block, the inboard of slide block connects the locating hole fuse, the locating hole fuse matches with locating hole, be shaped on oblique guide hole in the slide block, connect Angle Pin under solid plate, Angle Pin matches with oblique guide hole; On the described top board slide is installed, is shaped on chute in the slide, connect angle ejector rod on the chute, the head of angle ejector rod matches with back-off.
Injection mold slide block oblique top combination mould emptier of the present utility model during work, at first drives moving platen and solid plate die sinking by injection machine power, and slide block outwards slides under the effect of Angle Pin, drives the locating hole fuse and looses core, locating hole demoulding success; Then, push up on the top board, drive on push rod and the angle ejector rod and push up, because angle ejector rod is to be slidingly connected in the chute of slide, therefore, angle ejector rod is done oblique slip in last top, disengage with back-off, back-off demoulding success, last angle ejector rod ejects product outside the mould with push rod, and whole secondary mold releasability is finished.The locating hole of this programme and the back-off demoulding all are to utilize the power of mold injection machine own to drive, and need not to put in addition power, save cost.The locating hole demoulding adopts Angle Pin drive slide block smoothly to loose core, and the oblique top mode is adopted in the back-off demoulding, and both make up cooperation mutually, and the smooth demoulding of product is ejected.
