Description
Present patent application be invention and created name be the patent of invention of " a kind of press stripper apparatus " point
Case application, the filing date of original application December in 2013 10 days, Application No. 2013106713455.
Technical field
The present invention relates to a kind of stripper apparatus, particularly relate to a kind of press stripper apparatus.
Background technology
Using two square bars push rod as transmission pressure during the current demoulding, one end of push rod is placed on mould
Above tool, press is pressed in the other end of push rod, thus realizes the demoulding；During work, it is necessary to by one man operation pressure
Machine, another people holds up two push rod demouldings, there is great potential safety hazard, and needs two people's operations,
Waste of manpower；Additionally, push rod cannot stretch, so that make the push rod of differing heights, cause serious
The wasting of resources.
Summary of the invention
The invention provides a kind of press stripper apparatus, it is intended to when solving the press demoulding in prior art, need
People holds up two push rods, the problem that there is bigger potential safety hazard.
In order to solve above technical problem, the present invention is achieved through the following technical solutions: a kind of press demoulding dress
Put, including being positioned at the pressure head on press top, being positioned at press bottom and for supporting workpiece and mold assemblies
Workbench, also includes at least two push rod for the demoulding, and described each push rod is all by being arranged on its underpart
Magnetic stand be arranged on the upper end of mould.
Further, described mould include urceolus, install inner core on the table, be positioned at urceolus and inner core it
Between the cope match-plate pattern of upper end, between urceolus and inner core lower end and install lower bolster on the table, described
Push rod is uniformly arranged on the upper end of urceolus, and the diameter of push rod is less than the wall thickness of urceolus；The diameter of push rod is less than outward
The wall thickness of cylinder, makes push rod will not be pressed onto cope match-plate pattern, it is simple to urceolus pressure is fallen by push rod, it is achieved the demoulding.
Further, described workbench includes the base plate being connected in press bottom, is connected in the circle of plate upper surface
Ring, in described inner core is inserted in the centre bore of annulus and be fixed on base plate, described lower bolster is fixed on annulus
Upper surface, the external diameter of described annulus is less than the external diameter of lower bolster；Inner core and lower bolster are fixed by workbench,
And the external diameter of annulus is less than the external diameter of lower bolster, makes urceolus will not encounter workbench, be conducive to urceolus is smooth
Pressure falls.
Further, the lateral wall of described push rod extends axially downward out the block suitable with urceolus lateral wall；
Block is easy to the location of push rod, prevents push rod to be pressed on cope match-plate pattern.
Further, described push rod has three and is evenly distributed on the circumference of mould；Push rod quantity very little, is held
Being stressed can be relatively big, there is the hidden danger fractureed；Push rod quantity is too many, can cause each push rod discontinuity,
Thus the deformation of mould and workpiece can be caused.
Further, described each push rod upper end is equipped with push rod screwed hole, in described each push rod screwed hole all
Switching has one section of extension bar；It is easy to, according to the different length needing to adjust push rod, save resource and cost.
Further, the upper end described each push rod being positioned at push rod screwed hole is equipped with unthreaded hole, in described unthreaded hole
Being provided with straight screw sleeve, the screwed hole of centre of described straight screw sleeve and push rod screwed hole collectively constitute and lengthen
The screwed hole that the threaded portion of bar matches, described straight screw sleeve is connected on push rod by trip bolt；Logical
Cross trip bolt fastening straight screw sleeve, can effectively prevent extension bar from taking a turn for the worse.
Compared with prior art the invention have the advantage that in the present invention, the lower end of each push rod is equipped with magnetic power meter
Seat, is easily achieved the fixing of push rod and dismounting by the switch of rotation magnetic force gauge stand, uses magnetic force by push rod
It is fixed on mould upper end, it is to avoid the huge potential safety hazard existed during artificial rotary top bar.
Accompanying drawing explanation
The invention will be further described below in conjunction with the accompanying drawings:
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the structural representation of push rod of the present invention；
Structural representation when Fig. 3 is that in the present invention, straight screw sleeve installed by push rod；
Structural representation when Fig. 4 is that in the present invention, extension bar installed by push rod.
Detailed description of the invention
Refering to Fig. 1, a kind of press stripper apparatus, including being positioned at the pressure head 11 on press 1 top, being positioned at press 1
Bottom and for supporting workpiece 9 and the workbench of mould 3 assembly, also includes that at least two is for the demoulding
Push rod 2, described each push rod 2 is all arranged on the upper end of mould 3 by being arranged on the magnetic stand 4 of its underpart；
Described mould 3 include urceolus 32, install inner core 34 on the table, be positioned at urceolus 32 and inner core 34 it
Between the cope match-plate pattern 31 of upper end, between urceolus 32 and inner core 34 lower end and install lower mold on the table
Plate 33, described push rod 2 is uniformly arranged on the upper end of urceolus 32, and the diameter of push rod 2 is less than the wall of urceolus 32
Thick；Described workbench includes the base plate 13 being connected in press 1 bottom, is connected in the annulus 12 of plate upper surface,
The centre bore that described inner core 34 is inserted in annulus 12 is interior and fixing on base 13, and described lower bolster 33 is solid
Being scheduled on the upper surface of annulus 12, the external diameter of described annulus 12 is less than the external diameter of lower bolster 33；Described push rod 2
Lateral wall extend axially downward out the block 23 suitable with urceolus 32 lateral wall；Described push rod 2 has three
Individual and be evenly distributed on the circumference of mould 3.
Refering to Fig. 2 and Fig. 4, described each push rod 2 upper end is equipped with push rod screwed hole 21, described each top
In bar screwed hole 21, all switching has one section of extension bar 5.
Refering to Fig. 2, Fig. 3 and Fig. 4, the upper end that described each push rod 2 is positioned at push rod screwed hole 21 is all provided with
There is unthreaded hole 22, in described unthreaded hole 22, be provided with straight screw sleeve 6, the screwed hole of centre of described straight screw sleeve 6
61 collectively constitute the screwed hole 7 that the threaded portion with extension bar 5 matches, described straight spiral shell with push rod screwed hole 21
Stricture of vagina sleeve 6 is connected on push rod 2 by trip bolt 8.
During use, fixed on the table by the assembly of mould 3 and workpiece 9, i.e. inner core 34 is fixed on the end
On plate 13, lower bolster 33 is fixed on annulus 12 upper end, and three push rods 2 are uniformly placed on urceolus 32
Upper end, opens the switch of magnetic stand 4 simultaneously, makes magnetic stand 4 lead to magnetic, thus three push rods 2 are consolidated
Fixed；Rotating lengthening bar 5 as required, makes extension bar have a suitable working depth, tightens trip bolt 8,
