Abstract

The utility model provides a lateral core-pulling structure of an injection mold long-stroke slide, which is adaptable to the field of injection molds. The lateral core-pulling structure comprises a front mold plate, a rear mold plate engaged with the front mold plate and a slide arranged on the rear mold plate, wherein the front mole plate is fixedly equipped with guide slippers which are respectively arranged on two sides of the slide, each guide slipper is equipped with a guide groove inclining towards the outer side of an injection mold, and two sides of the slide are respectively fixedly equipped with a roller slidably arranged in each guide groove. As the rollers fixed on the slide move in the guide grooves of the guide slippers to further drive the slide to move towards the outer side of the mold, the lateral core-pulling structure of an injection mold long-stroke slide can complete long-stroke lateral core-pulling movement for the slide, and has the advantages of simple structure, low cost, high safety coefficient and beautiful mold mating.

Description

The side core-pulling structure of the capable position of the long stroke of injection mold

Technical field

The utility model belongs to the injection mold field, relates in particular to the side core-pulling structure of the capable position of the long stroke of a kind of injection mold.

Background technology

In existing die industry, the side core-pulling of the capable position of long stroke adopts oil cylinder, motor-driven usually or hypotenuse is strengthened and increase gradient and realizes.But adopt oil cylinder, motor can increase die space, the operation of installation mold can be many, and safety coefficient is lower, and cost also can increase; Though adopt the meeting of hypotenuse structure simpler, safety coefficient is very low, the size of hypotenuse has certain limitation, and is disconnected easily when its length is oversize, also influences attractive in appearance simultaneously.

The utility model content

Technical problem to be solved in the utility model be to provide a kind of simple in structure, with low cost, safety coefficient is high and the side core-pulling structure of the capable position of the long stroke of injection mold that the mould coupling is attractive in appearance.

The utility model is to realize like this, the side core-pulling structure of the capable position of the long stroke of a kind of injection mold, comprise that a front template, a rear pattern plate and that cooperates with described front template be located at the row position on the described rear pattern plate, be installed with a slider guide that lays respectively at both sides, described row position on the described front template, offer a guide runner that tilts to the injection mold outside on the described slider guide, both sides, described row position are installed with a roller that is slidedly arranged in the described guide runner respectively.

Below, described row position is provided with some wear plates that are fixedly arranged on the described rear pattern plate.

Be installed with on the described wear plate some can be to the guide pad of described row position guiding.

The outside of described row position also be provided with one be fixedly arranged on the described rear pattern plate can be to the limited block of the stroke limit of row position.

The side core-pulling structure of the capable position of the long stroke of the injection mold that the utility model provides, move in the guide runner of slider guide by the roller on the position of fixedly being expert at, and then drive the row position to the mould movement outside, to finish the long stroke side core-pulling motion of row position, the utlity model has advantage simple in structure, with low cost, that safety coefficient is high and the mould coupling is attractive in appearance.

The specific embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.

Consult Fig. 1～shown in Figure 4, the side core-pulling structure of the capable position of the long stroke of the injection mold that the utility model embodiment provides, comprise that a front template 1, a rear pattern plate 2 and that cooperates with described front template 1 be located at the row position 3 on the described rear pattern plate 2, be installed with a slider guide 4 that lays respectively at 3 both sides, described row position on the described front template 1, offer a guide runner 41 (as shown in Figure 3, Figure 4) that tilts to the injection mold outside on the described

slider guide

4,3 both sides, described row position are installed with a roller 5 that is slidedly arranged in the described guide runner 41 respectively.

In addition, 3 belows, described row position are provided with some wear plates 6 that are fixedly arranged on the described rear pattern plate 2, be installed with on the described wear plate 6 some can be to the guide pads 7 of described row position 3 guiding, the outside of described row position 3 also be provided with one be fixedly arranged on the rear pattern plate 2 can be to the limited block 8 of the stroke limit of row position 3.

Generally speaking, row position 3 does not need and postpones to loose core action, can be designed to the structure of guide runner 41 as shown in Figure 3, this guide runner 41 is made up of the groove of several sections inclinations, promptly when the injection mold die sinking, the side core-pulling action of row position 3 is finished also simultaneously to the mould movement outside in row position 3.

When row position 3 needs delay voltage, can be designed to structure as Fig. 4 guide runner 41, initial one section of this guide runner 41 is vertical groove, other several sections grooves for tilting, like this, when the injection mold die sinking, before front template 1 and rear pattern plate 2 were opened apart from M, row position 3 was not have demoulding action; When having only die sinking distance when front template 1 and rear pattern plate 2 greater than M, row position 3 just can along with front template 1 with the continuation die sinking of rear pattern plate 2 movement outside to mould, move with the side core-pulling of finishing row position 3.

The concrete operation principle of the side core-pulling structure of the capable position of the long stroke of injection mold that the utility model embodiment is provided is as follows: after injection moulding is finished, injection mold is from the mating surface somatotype of front template 1 with rear pattern plate 2, when front template 1 is opened with rear pattern plate 2, because slider guide 4 is fixedly arranged on the front template 1, roller 5 is fixedly arranged on the row position 3, along with the continuation of front template 1 with rear pattern plate 2 separates, roller 5 can be to the mould movement outside in the guide runner 41 of slider guide 4, and then roller 5 drives row position 3 to the mould movement outside, thereby finished the side core-pulling motion of capable position 3.

The side core-pulling structure of the capable position of the long stroke of injection mold provided by the utility model, by the 41 li motions of guide runner of the roller 5 on the position 3 of fixedly being expert at slider guide 4, and then drive row position 3 to the mould movement outside, to finish the long stroke side core-pulling motion of row position 3, has advantage simple in structure, with low cost, that safety coefficient is high and the mould coupling is attractive in appearance.

The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
