Abstract
The invention discloses a rotating angle pin mechanism, which is applied to a die. The rotating angle pin mechanism comprises angle pin seats and angle pins, wherein an arc clamping groove is formed in each angle pin seat; one end of each angle pin is arranged in each arc clamping groove in a rotating way, and the other end of each angle pin is matched with a product into an arc to form a reversed hook on the product. According to the rotating angle pin mechanism, the reversed hooks are upwards ejected through the angle pins when the reversed hooks in the annular product are formed, and at the same time, one end of each angle pin moves along each arc clamping groove in each angle pin seat, and the other end of each angle pin moves along the arc trajectory of the product until each reversed hook of the product is withdrawn, so that the problem that the reversed hooks in the annular product cannot be withdrawn through ordinary angle pins is solved.
Description
【Technical field】
The present invention relates to a kind of Slanting pin mechanism is and in particular to a kind of Slanting pin mechanism that can rotate.
【Background technology】
The plastic parts of product can carry out molding, for example, plastic parts such as shell of electronic product using plastic mould.Due to
The popularization of electronic product, the improvement for plastic mould also becomes widely studied problem.
When producing plastic cement products, it is frequently encountered the situation that overhead kick is existed on product, overhead kick part needs to use taper pin sometimes
Exit.Refer to shown in Fig. 1, the product in Fig. 1 is cyclic product 10, when having overhead kick 11 in the middle of cyclic product 10, adopts one
As taper pin cannot exit this overhead kick 11, cause the overhead kick 11 on this cyclic product 10 cannot molding.
In view of this, it is necessary in fact to develop a kind of new rotation Slanting pin mechanism, this rotation Slanting pin mechanism can exit
State the overhead kick in cyclic product.
【Content of the invention】
Therefore, it is an object of the invention to provide a kind of rotate Slanting pin mechanism, this rotation Slanting pin mechanism can exit ring-type and produce
Overhead kick in product.
In order to achieve the above object, the rotation Slanting pin mechanism of the present invention, is applied in mould, this rotation Slanting pin mechanism bag
Include：
Oblique pin base, this oblique pin base offers arc-shaped slot；
Taper pin, rotatably in described arc-shaped slot, the other end coordinates curved molding with product for this taper pin one end
Overhead kick on product.
It is preferred that the section of the arc-shaped slot opening up on described oblique pin base is in cross.
It is preferred that in the cross arc-shaped slot of molding, first milling out T-shaped arcuate groove with T-shaped knife, then by T-shaped arc
Groove milling becomes cross arc-shaped slot.
It is preferred that described taper pin one end in arc-shaped slot has circular hole, in this circular hole, it is equipped with round pin, this round pin
Slide in described arc-shaped slot in two ends so that one end of taper pin is rotatably in described arc-shaped slot.
Compared to prior art, the rotation Slanting pin mechanism of the present invention, during overhead kick in molding annular products, taper pin is upwards
While ejection, move along the arc-shaped slot in oblique pin base in this taper pin also one end, and makes the other end along the curved track of product
Mark moves, until exiting the overhead kick of product, solves the problems, such as that common taper pin cannot exit the overhead kick in cyclic product.
【Brief description】
Fig. 1 illustrates the structural representation of product.
Fig. 2 illustrates the structural representation that the present invention rotates Slanting pin mechanism.
Fig. 3 illustrates the schematic diagram of one angle when the present invention rotates Slanting pin mechanism shaped article.
Fig. 4 illustrates the schematic diagram of another angle when the present invention rotates Slanting pin mechanism shaped article.
【Specific embodiment】
Refer to shown in Fig. 2, Fig. 3 and Fig. 4, it depicts the present invention respectively and rotates the structural representation of Slanting pin mechanism, basis
Another angle when the schematic diagram of one angle and the present invention rotate Slanting pin mechanism shaped article during invention rotation Slanting pin mechanism shaped article
The schematic diagram of degree.
The rotation Slanting pin mechanism of the present invention, is applied in mould, and in the present embodiment, cyclic product 10 is provided with and falls at two
Hook 11, therefore, be provided with two sets of rotation Slanting pin mechanisms in molding overhead kick 11, this rotation Slanting pin mechanism includes：
Oblique pin base 100, this oblique pin base 100, on the liftout plate of described mould, this oblique pin base 100 offers arc card
Groove 110, the section of this arc-shaped slot 110 is in cross, in molding during this cross arc-shaped slot 110, is first milled out with T-shaped knife
Then T-shaped arcuate groove milling is become cross arc-shaped slot 110 by T-shaped arcuate groove；
Taper pin 200, this taper pin 200 one end has circular hole, is equipped with round pin 210 in this circular hole, slides in this round pin 210 two ends
In described arc-shaped slot 110, so that one end of this taper pin 200 is rotatably in described arc-shaped slot 110, should
Taper pin 200 other end and annular products 10 coordinate curved thus molding overhead kick 11.
Refer to shown in Fig. 3 and Fig. 4, after annular products 10 molding, described mould is molded, liftout plate drives taper pin
Seat 100 ejects upwards, and taper pin 200 tilts to exit under the ejection effect of oblique pin base 100, and that is, this taper pin 200 ejects annular upwards
While product 10, one end of this taper pin 200 is transported along arc-shaped slot 110 rotation in oblique pin base 100 also by round pin 210
Dynamic, and so that the other end of taper pin 200 is moved along the arching trajectory of annular products 10, until taper pin 200 exits annular products 10
Overhead kick 11.
The rotation Slanting pin mechanism of the present invention, during overhead kick in molding annular products, solving common taper pin cannot exit
Overhead kick problem in cyclic product.
