Abstract
The utility model relates to a straight-ejection large inclination core pulling mechanism which comprises an inclined ejection guiding block, an inclined ejection block, an ejector rod and a T-shaped block, wherein the inclined ejection guiding block is connected with the inclined ejection block through a T-shaped leg in a sliding and matching manner; the ejector rod is fixedly connected with the T-shaped block; a T-shaped sliding chute is arranged at the lower part of the inclined ejection block; the T-shaped block is connected with the T-shaped sliding chute in a sliding and matching manner; and a clearance groove is machined on the lower side of an inclined plane of the inclined ejection guiding block in the vertical direction. The straight-ejection large inclination core pulling mechanism adopts a straight ejector rod to realize ejection in the vertical direction, so the straight ejection structure is easy to machine, occupies small space and is low in the strength requirement of the ejector rod, furthermore, the defects that the inclined ejector rod is easy to bend and fracture are prevented, the manufacturing cost of dies is reduced and the movement safety and service life of the core pulling mechanism are improved.
Description
Technical field
The utility model relates to a kind of core-pulling mechanism, particularly relates to the big gradient core-pulling mechanism in a kind of straight top.
Background technology
In die design process, can run into product structure as shown in Figure 1 usually, this class formation is with the ramp-roof structure rubber moulding usually, and is as shown in Figure 2.But tiltedly push up mechanism usually as produce following problem: (1) because the product button bit is oversize, and gradient is too big, curving push rod easy to break, wherein tiltedly push up mechanism usually with the angle of vertical direction less than 12 degree, need adopt reinforcing mechanisms when spending greater than 12; (2) since this type of tiltedly top mechanism eject by angle ejector rod is oblique, so angle ejector rod takes up space greatlyyer on mould, is unfavorable for arranging of peripheral mechanism, makes mould structure complicated, the increase die cost; (3) inclined hole processing difficulties is difficult to control position, inclined hole hole precision, and when assembling also difficulty comparatively.
Summary of the invention
The utility model technical problem to be solved provides a kind of big gradient core-pulling mechanism in straight top that can improve mechanism kinematic security and service life
The utility model solves the technical scheme that its technical problem adopted: provide a kind of straight top big gradient core-pulling mechanism, comprise oblique top guide pad, slanted kicking block, push rod and T type piece, said oblique top guide pad is joined through oblique T type pin cunning with slanted kicking block and is connected; Said push rod is fixedly connected with T type piece; Said slanted kicking block bottom is provided with T type chute; Said T type piece is joined with said T type chute cunning and is connected; Have avoiding hollow groove on guide pad inclined-plane, the said oblique top downside vertical direction.
Have avoiding hollow groove on guide pad inclined-plane, the said oblique top downside vertical direction.
Said push rod top is provided with groove; Said T type piece is fixed in the groove of push rod through screw.
Said depth of groove is 1mm.
Beneficial effect
Owing to adopted above-mentioned technical scheme, the utility model compared with prior art has following advantage and good effect: the utility model is directly to eject from vertical direction to push rod; This straight roof construction, easy to process, institute takes up space little; And it is not high to the push rod requirement of strength; Can prevent defectives such as angle ejector rod is crooked easily and fracture, can reduce die manufacturing cost, improve mechanism kinematic security and service life.

The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction the utility model scope.Should be understood that in addition those skilled in the art can do various changes or modification to the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
The embodiment of the utility model relates to the big gradient core-pulling mechanism in a kind of straight top, like Fig. 3 and shown in Figure 4, comprises oblique top guide pad 1, slanted kicking block 2, push rod 3 and T type piece 4.Said oblique top guide pad 1 is joined through oblique T type pin cunning with slanted kicking block 2 and is connected.Push rod 3 tops are provided with groove, and T type piece 4 is fixed on through screw in the groove of push rod 3, and the degree of depth of groove is 1mm, and the depth of groove that T type piece 4 is hidden in push rod 3 is the 1mm place, can prevent to rotate.Slanted kicking block 2 bottoms are provided with T type chute, and T type piece 4 is joined with this T type chute cunning and is connected.Have avoiding hollow groove on the said oblique top guide pad 1 inclined-plane downside vertical direction, be beneficial to the motion that ejects of push rod 3 and T type piece 4 assemblies.The gradient of oblique T type pin and ejection stroke utilize the trigonometric function relation to calculate by the required stripping stroke of known product.
As shown in Figure 5; Tiltedly the top guide pad is fixed on the male model benevolence of mould through screw; When the injection machine ejection system drives ejector retainner plate, so that push rod upwards pushes, because tiltedly the top guide pad is that oblique T type pin cunning is joined connection in slanted kicking block; Directly to active force under slanted kicking block along oblique T type pin oblique on move meanwhile slanted kicking block and T type piece between also relatively laterally slide (see figure 6) push rod this moment.When ejection stroke reached the S2 height, the infeed stroke of slanted kicking block was S1, promptly deviate from the product back-off fully and was in safe distance, and accomplish this mechanism action this moment, as shown in Figure 7.
Be not difficult to find that the utility model is directly to eject this straight roof construction from vertical direction to push rod; Easy to process, institute takes up space little, and not high to the push rod requirement of strength; Can prevent defectives such as angle ejector rod is crooked easily and fracture, can reduce die manufacturing cost, improve mechanism kinematic security and service life.
