Abstract

The utility model discloses a simple cross core-pulling mechanism for an injection mould. The simple cross core-pulling mechanism for the injection mould comprises an oblique guide pillar fixing seat, an oblique guide pillar, a slide seat, a horizontal slide insert, a cross slide insert, a T-shaped driving block, a spring and a limit screw component, the cross slide insert penetrates through the horizontal slide insert, reversely breaks away and resets under the action of the T-shaped driving block, penetrates through the T-shaped driving block and extends to the bottom of a rear mould core, the T-shaped driving block is fixedly connected with a slider seat through a screw, and the oblique guide pillar is mounted on the side surface of a front mould core and is fixedly mounted on the oblique guide pillar fixing seat. By the aid of the simple cross core-pulling mechanism, the structure of the mould is simplified, reliability of production operation is improved, late maintenance is simple and rapid, and manufacture and maintenance costs are greatly reduced.

Description

The injection mold staggered form simple mechanism of loosing core

Technical field

The staggered form that the utility model the relates to a kind of injection mold field simple mechanism of loosing core.

Background technology

In the injection mold field, square lifter takes off back-off and the interior line position twice parting mode of loosing core is used quite extensive, reliability is relatively poor at the volley for the former inclined-ejecting inverted buckle demoulding version, easily cause sticking oblique top to pull product, and eject and have some setbacks and stuck, the phenomenons such as burn oblique top and endoporus, the processing maintenance is also inconvenient, cost is high, waste time and energy, line position twice parting core-pulling die structure is complicated in the latter, and need to increase template and serial auxiliary control unit and could realize that twice parting breaks away from the purpose of back-off, this version has improved cost of manufacture greatly, and this version was produced in early stage, assembling and later period maintenance aspect are all very inconvenient, thereby directly have influence on productivity effect.

The utility model content

The technical problems to be solved in the utility model is to provide a kind of simple in structure, processing, installation, easy to maintenance, and mechanism kinematic is the injection mold staggered form simple mechanism of loosing core smoothly.

For solving the problems of the technologies described above, the utility model is realized by following scheme: the injection mold staggered form simple mechanism of loosing core is comprised of Angle Pin holder, Angle Pin, line position seat, horizontal line position mold insert, staggered form line position mold insert and T shape drive block, spring, limited screw parts.

Further, described staggered form line position mold insert passes horizontal line position mold insert, staggered form line position mold insert carries out back-off and breaks away from and reseting movement under the effect of T shape drive block, and pass T shape drive block, extend to the bottom of rear cavity, this T shape drive block is connected with take-up housing and is screwed, and Angle Pin is installed in the front cavity side, and Angle Pin is fixedly mounted on the oblique guide bracket holder.

The utility model is convenient for installation and maintenance, mechanism kinematic is smooth and easy, the characteristics such as take up room little, manufacture craft is simple, and is not fragile, avoided the existing defective of inclined-ejecting inverted buckle demoulding, also avoided simultaneously the increase of the numerous and diverse and cost of interior line position twice parting pulled core structure processing and maintenance, this utility model has been simplified mould structure, has improved the reliability of producing the running row, simple and fast aspect the safeguarding of later stage greatly reduces and makes and maintenance cost.

The specific embodiment

As shown in Figure 1, this injection mold staggered form is loosed core simple mechanism by Angle Pin holder 1, Angle Pin 2, line position seat 3, horizontal line position mold insert 4, staggered form line position mold insert 5 and T shape drive block 6, spring 7, limited screw 8 parts form, described staggered form line position mold insert 5 passes horizontal line position mold insert 4, staggered form line position mold insert 5 carries out back-off and breaks away from and reseting movement under the effect of T shape drive block 6, and pass T shape drive block 6, extend to the bottom of rear cavity 9, this T shape drive block 6 is connected with take-up housing and is screwed, Angle Pin 2 is installed in front cavity 10 sides, Angle Pin 2 is fixedly mounted on the oblique guide bracket holder 1, the injection mold staggered form simple mechanism of loosing core, will be hardly attainable structure by simple conversion with pass through and step down, it is come true, all linked with one another each other, and simple, reliable; Such as Fig. 1, Fig. 3, Fig. 4, Fig. 5, shown in Figure 6: staggered form line position mold insert 5 is front-installed from front cavity 10, pass through horizontal line position mold insert 4, be slidingly matched by T-slot and T shape drive block 6, the concave station that is provided with hanging platform and internal mold on the mold insert assembles spacing, with convenient smoothly assembling, T shape drive block 6 and horizontal line position mold insert 4 are bumped into respectively location in the line position seat, be screwed behind from line position, horizontal line position mold insert 4 middle part boreholes can therefrom pass the staggered form mold insert smoothly, as shown in Figure 2, during die sinking, line position seat 3 is backward motion under the drive of Angle Pin 2, thereby the horizontal line position mold insert 4 of drive and staggered form line position mold insert 5 break away from direction along back-off to move, after back-off breaks away from and reaches certain safe distance, the line position assembly is finished the action of loosing core in the effect of limited screw 8 and spring 7, and product is release will be finished by common pushing method.
