Abstract
The utility model provides a kind of Mold pentroof structure, including the front cavity and rear cavity to contact with each other, includes an oblique top head successively on the direction from front cavity to rear cavity, is located in rear cavity, one end is contacted with front cavity；One angle ejector rod extends from the direction where rear cavity extroversion front cavity and enters in the oblique top head, and the other end of the angle ejector rod is connect with the oblique top head internal-flange bolt.Due to the use of being bolted so that angle ejector rod top surface is adjacent to inside end face and oblique top head in other words, so no longer as stress in the prior art concentrates on pin hole, but power is tiled to entire oblique top rod end surface, is reduced pin or the probability of pin hole fracture.
Description
Technical field
The utility model is related to mould applications more particularly to a kind of Mold pentroof structures.
Background technology
Die pitched roof also known as the oblique tip, oblique top are the usual theory of the Pearl River Delta area die industry based on HongKong-funded mould factory
Method is the mechanism for being used for formed product inner barb in mold design, is suitable for fairly simple barb situation.
Fig. 1 is please referred to, mold cavity 2 is between front cavity 1 and rear cavity 3 in traditional mold, after oblique top head 6 is located at
In mode 3, and upper end is contacted with cavity 2, and angle ejector rod 5 is extended into from 3 lower section of rear cavity in oblique top head 6 obliquely, is being molded
When, in product ejection process, it is upward that angle ejector rod 5 pushes up oblique top head 6, is detached from rear cavity 3, motion process together with product
In, 6 opposing product of oblique top head has horizontal direction displacement, to deviating from from product button bit, with ensure can be light after product ejection
Pine is taken out.
In the prior art, it is connected using pin between angle ejector rod 5 and oblique top head 6, this connection is often so that angle ejector rod 5 pushes up
Face can not be adjacent to inside oblique top head 6, and the two is made to generate a certain distance in 5 axial direction of angle ejector rod, upward in angle ejector rod 5 in this way
When oblique top head 6 being pushed to move, only by the independent stress of pin and upward thrust only is generated in two pin holes 4, pin hole 4 exists
Herein can be by shearing force, which makes pin hole 4 deform or be broken, to cause oblique top head 6 to be taken off from angle ejector rod 5
It falls, can smash mold leads to damp production, or even under the ignorant situation of personnel, and molding again can damage front and back mode by pressure, damage
It loses heavy.
Utility model content
The utility model provides a kind of Mold pentroof structure, for solving the above problems.
In order to achieve the above objectives, the utility model provides a kind of Mold pentroof structure, including mutually forms the preceding mould of cavity
Renhe rear cavity includes successively on the direction from front cavity to rear cavity
One oblique top head is located in rear cavity, and one end is contacted with cavity；
One angle ejector rod extends and enters in the oblique top head, the oblique top from the direction where rear cavity extroversion front cavity
The other end of bar is connect with the oblique top head internal-flange bolt.
Preferably, the axial direction of the bolt is parallel with the axial direction of the angle ejector rod.
Preferably, angle ejector rod pin also between the oblique top head connects, it is remote that the pin is located at the bolt
Side from the front cavity.
Preferably, the axial direction of the pin and the angle ejector rod is axially vertical.
Preferably, the axial direction of pin hole where the pin perpendicular to the angle ejector rod, and in the axis of the pin
Run through the angle ejector rod up to reaching the oblique top head another side from the one side of the oblique top head upwards.
Preferably, described be bolted to use grub screw to connect.
Compared with prior art, the utility model has the beneficial effects that：The utility model provides a kind of Mold pentroof structure,
Front cavity and rear cavity including mutually forming cavity include successively on the direction from front cavity to rear cavity
One oblique top head is located in rear cavity, and one end is contacted with cavity；
One angle ejector rod extends and enters in the oblique top head, the oblique top from the direction where rear cavity extroversion front cavity
The other end of bar is connect with the oblique top head internal-flange bolt.Due to the use of being bolted so that angle ejector rod top surface end face in other words
Be adjacent to inside oblique top head, so no longer as stress in the prior art concentrates on pin hole, but by power tile to it is entire tiltedly
Mandril end face reduces pin or the probability of pin hole fracture.
Description of the drawings
Fig. 1 is Mold pentroof structure schematic diagram in the prior art；
Fig. 2 is Mold pentroof structure schematic diagram provided by the utility model.
Prior art illustration：1- front cavitys, 2- cavities, 3- rear cavities, 4- pin holes, 5- angle ejector rods, 6- oblique top heads；
The utility model illustrates：100- front cavitys, 200- cavities, 300- rear cavities, 400- pin holes, 500- angle ejector rods,
600- oblique tops head, 700- grub screws.
Specific implementation mode
To keep the above objects, features, and advantages of the utility model more obvious and easy to understand, below in conjunction with the accompanying drawings to this
The specific implementation mode of utility model is described in detail.
Fig. 2 is please referred to, the utility model provides a mold ramp-roof structure, includes from top to bottom
One oblique top head 600 is located in rear cavity 300, and upper end is contacted with cavity (not shown)；
One angle ejector rod 500 is extended upwardly into from 300 lower section of rear cavity in the oblique top head 600, and the angle ejector rod 500 pushes up
Face is bolted with 600 inside use of the oblique top head.
Specifically, the top surface of angle ejector rod 500 is perpendicular to the axial direction of angle ejector rod 500, is bolted and specially uses nothing
Head screw 700 connects, and the axial direction of grub screw 700 is parallel with the axial direction of angle ejector rod 500, therefore is also perpendicular to angle ejector rod
500 top surface.
After angle ejector rod 500 and oblique top head 600 are bolted, pin hole 400, pin are machined on the oblique top head 600
Nail hole 400 is located at 700 lower section of grub screw.The pin hole 400 perpendicular to angle ejector rod 500 axial direction, perpendicular to angle ejector rod 500
In axially direction, pin hole 400 is through to opposite face on one side from oblique top head 600, and angle ejector rod 500 has been run through in centre.
The utility model is due to the use of being bolted so that is adjacent to inside 500 top surface of angle ejector rod and oblique top head 600, in this way
No longer as stress in the prior art concentrates on pin hole 400, but power is tiled to entire angle ejector rod top surface, reduces pin
Or the probability that pin hole 400 is broken.
Obviously, it is new without departing from this practicality can to carry out utility model various modification and variations by those skilled in the art
The spirit and scope of type.If these modifications and variations of the present invention belong to the claims of the present invention and its equivalent technology
Within the scope of, then the utility model is also intended to including these modification and variations.
