Description

A kind of injection mold with cover half oblique top mechanism
Technical field
The present invention relates to a kind of injection mold, refer in particular to a kind of injection mold with cover half oblique top mechanism.
Background technology
In injection mold, the appearance surfaces of goods generally is located at cover half, and the thimble impression that demoulding thimble is produced goods when the back mould takes off material is positioned at invisible position.If appearance surfaces has back-off structure or surfaces externally and internally that back-off structure is all arranged, then cover half be provided with oblique top take off back-off or core-pulling mechanism will be inevitable.The existing mold structure is at cover half cover half ejector retainner plate assembly to be set, and between top clamping plate and cover half die cavity, hot flow path is set, between cover half push pedal and top clamping plate spring is set, dynamic model overcomes spring force by the ejector retainner plate release link when the mold closing cover half push pedal is killed on top clamping plate.When die sinking was finished in injection moulding, the cover half push pedal drove the action of loosing core of angle ejector rod or slide block guiding oblique top mold insert under spring force promotes, and the dynamic mould core band workpiece and left the cover half die cavity and finish the die sinking action simultaneously, continues following routine and takes off the material operation.Big when the angle ejector rod inclination angle, oblique top quantity is many, during oblique top dropout distance, the quantity of spring and height will increase very big, cause the thickness of cover half to increase greatly, and the maintenance probability of mould damage increases greatly, influence production operation efficiency.
Summary of the invention
The objective of the invention is to solve above-mentioned prior art problems, the injection mold with cover half oblique top mechanism that a kind of dependable performance, mold thickness are little, can effectively reduce die manufacturing cost is provided.The present invention is achieved in that
A kind of injection mold with cover half oblique top mechanism, comprise top clamping plate, cover half oblique top mechanism and dynamic mould core, described cover half oblique top mechanism comprises cover half ejector retainner plate, cover half angle ejector rod, cover half ejector retainner plate pull bar, pull bar dropout guide block and spring, pull bar dropout guide block is fixed on the top clamping plate, described cover half ejector retainner plate pull bar is provided with square groove, pull bar release pin and spring, cover half ejector retainner plate pull bar one end is hingedly fixed on the dynamic mould core, and the pull bar release pin is slidingly connected with the pull bar dropout guide block that is provided with crowning.
Described cover half ejector retainner plate pull bar is by square groove and cover half ejector retainner plate clasp joint.
Described spring passes cover half ejector retainner plate pull bar by screw rod and is installed on the dynamic mould core.
Described cover half ejector retainner plate pull bar is hingedly fixed on the dynamic mould core by the pull bar free bearing.
Described cover half ejector retainner plate is fixed with release link.
Described cover half ejector retainner plate is provided with groove.
The present invention adopts the cover half ejector retainner plate pull bar that is hingedly mounted on the dynamic model, driving the cover half ejector retainner plate in the die sinking process moves, promoting the cover half angle ejector rod ejects workpiece from the cover half die cavity, the oblique top of realization cover half is taken off back-off, to the effect of lifting of pull bar release pin cover half ejector retainner plate pull bar and cover half ejector retainner plate are thrown off by pull bar dropout guide block then, the demoulding work from the dynamic mould core of the goods of proceeding routine again.Compare with the mould of the front mould ejector retainner plate that adopts spring thrust, do to effectively reduce the thickness and the weight of mould, and can reduce the maintenance of mould, improved production efficiency, have tangible economic benefit.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the right view of Fig. 1.
The specific embodiment
For being illustrated more clearly in technical scheme of the present invention, the present invention is further described below in conjunction with embodiment.
As Fig. 1, shown in Figure 2, a kind of injection mold with cover half oblique top mechanism, comprise top clamping plate 1, cover half oblique top mechanism 2 and dynamic mould core 5, described cover half oblique top mechanism 2 comprises cover half ejector retainner plate 202, cover half angle ejector rod 204, cover half ejector retainner plate pull bar 205, pull bar dropout guide block 201 and spring 207, pull bar dropout guide block 201 is fixed on the top clamping plate 1, described cover half ejector retainner plate pull bar 205 is provided with square groove 211, pull bar release pin 210 and spring 207, cover half ejector retainner plate pull bar 205 1 ends are hingedly fixed on the dynamic mould core 5, and pull bar release pin 210 is slidingly connected with the pull bar dropout guide block 201 that is provided with crowning 203.
As shown in Figure 1 and Figure 2, described cover half ejector retainner plate pull bar 205 is by square groove 211 and cover half ejector retainner plate 202 clasp joints.
As shown in Figure 1 and Figure 2, described spring passes cover half ejector retainner plate pull bar 205 by screw rod and is installed on the dynamic mould core.
As shown in Figure 1 and Figure 2, described cover half ejector retainner plate pull bar 205 is hingedly fixed on the dynamic mould core 5 by pull bar free bearing 209.
As shown in Figure 1 and Figure 2, described cover half ejector retainner plate 202 is fixed with release link 206.
As shown in Figure 2, described cover half ejector retainner plate 202 is provided with groove 212.
As shown in Figure 1 and Figure 2, when mould is finished the injection moulding die sinking, cover half ejector retainner plate pull bar 205 hooks cover half ejector retainner plate 202 promotion cover half angle ejector rods 204 by square groove 211 workpiece 4 is ejected from cover half die cavity 3 under the effect of spring 207, realize that the oblique top of cover half is taken off back-off; Pull bar release pin 210 edge along pull bar dropout guide block 201 under spring 207 pressure slides in this process.After cover half takes off back-off, pull bar release pin 210 is just in time lifted by the bossing 203 at pull bar dropout guide block 201 edges, the square groove 211 of cover half ejector retainner plate pull bar is broken away from cover half ejector retainner plate 202,202 stop motions of cover half ejector retainner plate prepare to carry out the demoulding work of conventional workpiece 4 from the dynamic mould core 5.Workpiece 4 is finished when taking off material, mould matched moulds, the dynamic mould core face promotes cover half ejector retainner plate 202 by release link 206 and gets back to original position, cover half ejector retainner plate pull bar 205 square groove 211 under spring 207 active forces hooks cover half ejector retainner plate 202 once more, prepares to carry out the work in next cycle.
The foregoing description is to further specify of the present invention, is not to concrete qualification of the present invention, therefore does the variation that is equal to according to the present patent application claim, is the scope that contains in the present invention.
