Wherein, the rewinding hole is blind hole.
Wherein, the rewinding hole is located at the center of injection punch head front end.
Wherein, the section in the rewinding hole is isosceles trapezoid.
Wherein, the rewinding hole is round table-like.
Wherein, the edge of the end face of the front end of injection punch head is equipped with concave step.
Wherein, the inner ring surface of the step is inclined-plane.
Wherein, the rear end face of injection punch head is outward extended with the mounting post for clamping installation.
Wherein, mounting hole is offered in mounting post, mounting hole extends in injection punch head.
Wherein, the periphery of mounting post sets multiple equally distributed mounting surfaces.
Beneficial effects of the present invention:
The present invention provides a kind of aluminium alloy compression casting thin-wall material cake batch cutting edge of a knife or a sword formed punch, including injection punch head, the injection punch head
Front end be equipped with rewinding hole, injection punch head stroke arrive certain position when, increased rewinding hole start generate recycling squeeze formation
Expect the material of cake, alleviate the pressure in extrusion process to molding mass cake, so that molding mass cake periphery will not squeeze out batch cutting edge of a knife or a sword and fly material.
Compared to the prior art, the configuration of the present invention is simple, the molding mass cake after saving discharging remove batch cutting edge of a knife or a sword or fly the process of material, improve
Working efficiency, while batch cutting edge of a knife or a sword will not be squeezed out and fly material, it avoids batch cutting edge of a knife or a sword and flies material scald staff, improve safety.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings, but the embodiment in attached drawing is not constituted to any limit of the invention
System, for those of ordinary skill in the art, without creative efforts, can also obtain according to the following drawings
Other attached drawings.
Fig. 1 is the structural schematic diagram of injection punch head of the invention；
Fig. 2 is the sectional view of injection punch head of the invention；
Drawing reference numeral of the Fig. 1 into Fig. 2 is as follows:
1, injection punch head；2, rewinding hole；3, concave step；4, mounting post；5, mounting hole.
Specific embodiment
The invention will be further described with the following Examples.
As depicted in figs. 1 and 2, the present invention provides a kind of aluminium alloy compression casting thin-wall material cake batch cutting edge of a knife or a sword formed punch, including injection punch head
1, the injection punch head 1 is cylindrical body, and the center of the front end of injection punch head 1, which is equipped with, can be used for recycling overstocked material cake
Rewinding hole 2.The other positions in addition to center can also be arranged in the rewinding hole 2.Be located at center, be in order to
When producing injection punch head 1, it is easy positioning production.The rewinding hole 2 is blind hole, it is also an option that not preferred injection punch head 1
For through-hole, but the injection punch head 1 needs to be sealed the through-hole filling, then selects blind hole more advantageous when installation
In the installation of injection punch head 1, more scope of applications are adapted to.The rewinding hole 2 of injection punch head 1 is round table-like hole, and rewinding hole 2 exists
Diameter on the end face of 1 front end of injection punch head is 25 millimeters, another diameter of rewinding hole 2 in injection punch head 1 is 15 millimeters.
The rewinding hole 2, cross section are isosceles trapezoid, and rewinding hole 2 can be cylindric or coniform hole.Using coniform
After the discharging of rewinding hole, there is more sharp part, be easy to stab staff.Using round table-like rewinding hole 2, due to round table-like
Rewinding hole 2 on have inclined-plane, be more advantageous to and squeezing reclaimed materials cake material, while also the same processing and manufacturing.Rewinding hole 2 can be with
Using the hole of the other shapes such as triangular prism shape or rectangular-shape.
Preferably, the end face of the front end of injection punch head 1 is equipped with the concave step 3 with inclined-plane, and the inclined-plane is bumps
The inner ring surface of step 3.The concave step 3 reduces the suffered resistance and interference during the motion of injection punch head 1.Institute
Stating concave step 3 can also be non-band inclined-plane.In 1 motion process of injection punch head, inclined-plane slows down injection punch head 1 in die casting
The resistance being subject in the process.
Preferably, the rear end face of injection punch head 1 is outward extended with the mounting post 4 for clamping installation, the circumference of mounting post 4
Face is equipped with multiple equally distributed mounting surfaces.Mounting hole 5 is offered in mounting post 4, mounting hole 5 extends in injection punch head.Institute
1 rear end of injection punch head stated is equipped with mounting hole 5 and mounting surface facilitates the clamping of injection punch head 1 and is mounted on die casting equipment.It is described
Mounting post 4 section can also be square either rectangle.
Specific works engineering: the mounting post 4 of injection punch head 1 and the clamping of mounting hole 5 are mounted on die casting equipment, injection punching
The position that first 1 injection is completed is set as 358 millimeters and fixes.Die casting equipment is opened, injection punch head 1, which starts to advance, pushes material to mould
In tool, material cake is formed, when 1 stroke of injection punch head is to 350 millimeters, the rewinding hole 2 of 1 front end of injection punch head starts to generate recycling
The material of pressing material cake alleviates material to the extruding force of material cake and mold, avoids the extruding on material cake and forms batch cutting edge of a knife or a sword or fly material,
It is advanced into 358 millimeters of completion press casting procedures.The material cake periphery of formation not will form batch cutting edge of a knife or a sword or fly material, without criticizing to material cake
Cutting edge of a knife or a sword or the treatment process for flying material, while also improving the safety of staff.
A kind of present invention aluminium alloy compression casting thin-wall material cake batch cutting edge of a knife or a sword formed punch is described in detail above, it is used herein
A specific example illustrates the principle and implementation of the invention.The above embodiments are only used to help understand originally
The core concept of invention；At the same time, for those skilled in the art, according to the thought of the present invention, in specific embodiment
And there will be changes in application range, in conclusion the contents of this specification are not to be construed as limiting the invention.
