Description
Technical field
The utility model relates to the two mould emptiers of a kind of injection mold lever, belongs to the mould of plastics field.
Background technology
Adopt injection mold to produce plastic product, Hollow barrel opaque product for example, the structure of traditional moulds normally adopts die cavity to be coated on the outer wall of product; Core passes product and comes moulding, and its shortcoming is: product die sinking often regular meeting stay in the die cavity, and can not guarantee that product stays core side; Can not eject through the ejection system of core side after the mould die sinking; Cause the product snap gauge to deviate from, mould breaks down, and influence is produced.
Summary of the invention
The purpose of the utility model is in order to overcome the shortcoming of prior art; A kind of mould open/close mould power that utilizes is provided; Adopt lever principle; During the demoulding product is depressed, made product break away from die cavity, the two mould emptiers of injection mold lever that eject smoothly by the ejection system of mold cores side then with core operation.
The technical scheme of the two mould emptiers of the utility model injection mold lever is: comprise compound plate and following compound plate on the mould, last compound plate connects die cavity through cushion block, and the mould pin is installed on the following compound plate; Ejector retainner plate and following ejector retainner plate are set in the mould pin, connect drive link on the last ejector retainner plate, on the mould pin gripper shoe is installed; Core fixing plate is installed on the gripper shoe, is connected core on the core fixing plate, drive link passes core fixing plate and connects stripper plate; Core passes between stripper plate and the die cavity and constitutes die cavity, and the product of moulding is arranged in the die cavity, it is characterized in that a piece on the described cavity lateral; Prop up piece and connect lever through pin, one of lever is shaped on protruding rail, is equipped with roller on the sidewall of core fixing plate; Roller matches with protruding rail, and the other end of lever is stretched in the cushion block, and connects the die cavity pressing plate; The die cavity pressing plate connects the die cavity depression bar down, and the die cavity depression bar stretches in the die cavity and contacts with product.
The utility model discloses the two mould emptiers of a kind of injection mold lever, during the demoulding, move downward by injection machine power drive core and core fixing plate; The roller that is installed on the core fixing plate sidewall is contacted with the protruding rail of one on lever, and this lever perk makes the other end of lever oppositely depress around a piece; Because the other end of lever is stretched in the cushion block, and connect the die cavity pressing plate, the die cavity pressing plate connects the die cavity depression bar down; The die cavity depression bar stretches in the die cavity and contacts with product, and just the other end of lever drive die cavity pressing plate and die cavity depression bar press down, and the die cavity depression bar presses down product; Make product stay outside the core from die cavity, to deviate from core operation downwards; Product can snap gauge, drives upper and lower ejector retainner plate by injection machine power at last, and upper and lower ejector retainner plate drives drive link; Drive link drives stripper plate product is ejected outside the mould, and the demoulding is accomplished.This programme adopts lever principle, utilizes folding mould power to drive lever and presses down, and product is stayed on the mold cores, and die cavity is snap gauge not, and product ejects smoothly.
The two mould emptiers of the injection mold lever of the utility model; Be shaped on groove on the described die cavity, be equipped with back-moving spring outside the die cavity depression bar between groove and die cavity pressing plate, during matched moulds; Back-moving spring plays the auxiliary reset effect to the die cavity depression bar, and the die cavity depression bar resets and more puts in place.The head of described die cavity depression bar is shaped on avoiding hollow groove, and avoiding hollow groove matches with the core head, avoids core and die cavity depression bar damaged in collision.
Description of drawings
Fig. 1 is the two mould emptier structural representations of the utility model injection mold lever.
The specific embodiment
The utility model relates to the two mould emptiers of a kind of injection mold lever, and is as shown in Figure 1, comprises compound plate 1 and following compound plate 2 on the mould, and last compound plate 1 connects die cavity 4 through cushion block 3; Mould pin 5 is installed on the following compound plate 2, ejector retainner plate 6 and following ejector retainner plate 7 are set in the mould pin, connect drive link 8 on the last ejector retainner plate 6; Gripper shoe 9 is installed on the mould pin 5, core fixing plate 10 is installed on the gripper shoe, connect core 11 on the core fixing plate; Drive link 8 passes core fixing plate 10 and connects stripper plate 12, and core 11 passes between stripper plate 12 and the die cavity 4 and constitutes die cavity, and the product 13 of moulding is arranged in the die cavity; It is characterized in that a piece 15 on described die cavity 4 sidewalls, a piece 15 connects lever 17 through pin 16, and one of lever 17 is shaped on protruding rail 18; Be equipped with roller 19 on the sidewall of core fixing plate 10, roller 19 matches with protruding rail 18, and the other end of lever 17 is stretched in the cushion block 3; And connect die cavity pressing plate 20, the die cavity pressing plate connects die cavity depression bar 21 20 times, and die cavity depression bar 21 stretches in the die cavity and contacts with product 13.During the demoulding, drive core 11 by injection machine power and move downward, the roller 19 that is installed on core fixing plate 10 sidewalls is contacted with the protruding rail 18 of one on lever with core fixing plate 10; This lever perk makes the other end of lever 17 oppositely depress around a piece 15, because the other end of lever 17 is stretched in the cushion block 3; And connect die cavity pressing plate 20, the die cavity pressing plate connects die cavity depression bar 21 20 times, and die cavity depression bar 21 stretches in the die cavity 4 and contacts with product 13; The die cavity of the other end of lever drive just pressing plate 20 presses down with die cavity depression bar 21; Die cavity depression bar 21 presses down product 13, makes product 13 stay that core 11 is outer to be deviate from from die cavity 4 with core operation downwards, and product can snap gauge; Drive upper and lower ejector retainner plate 6,7 by injection machine power at last; Upper and lower ejector retainner plate 6,7 drives drive link 8, and drive link 8 drives stripper plate 12 product 13 is ejected outside the mould, and the demoulding is accomplished.This programme adopts lever principle, utilizes folding mould power to drive lever and presses down, and product is stayed on the mold cores, and die cavity is snap gauge not, and product ejects smoothly.Be shaped on groove 22 on the described die cavity 4, be equipped with back-moving spring 23 outside the die cavity depression bar 21 between groove 22 and die cavity pressing plate 20, during matched moulds, back-moving spring plays the auxiliary reset effect to the die cavity depression bar, and the die cavity depression bar resets and more puts in place.The head of described die cavity depression bar 21 is shaped on avoiding hollow groove 24, and avoiding hollow groove 24 matches with core 11 heads, avoids core and die cavity depression bar damaged in collision.
