Specific embodiment
The present invention will be further explained with reference to the accompanying drawing.
As shown in attached drawing 2 to attached drawing 5, a kind of automatic material jacking injection forming mold of table supporting frame, including cope plate 1,
Lower template 2, top plate 3, mandril 5 and discharge component, the cope plate 1 are arranged by guide post 6 relative to lower template open mold, institute
The lower section that lower template 2 is arranged in 3 spacing of top plate is stated, and the top plate 3 is arranged relative to lower template up and down displacements, the top plate 3
On be vertically installed with several mandrils 5, the top activity of the mandril 5 passes through lower template 2 and protrudes into the type chamber 20 of lower template, closes
When mould, mandril top is no more than the bottom surface of type chamber 20, at least one described discharge component is arranged in lower template 2 and top plate 3, institute
Discharge component is stated to be promoted under opening and closing mould state or lower coping 3, in molding, mandril 5 and mandril 3 press to initial position,
It is opened after injection molding, the top plate 3 shifts up automatically and eject moulding by discharge component, which reduces people
Work participates in, and saves time, raising efficiency, while mitigating labor intensity.The mandril 5 is hollow rod body structure, when die sinking
The mandril 5 is connected to air pump 21, and the mandril 5 sprays compressed gas into the type chamber 20 of lower template 2, as shown in Fig. 6, described
The top of mandril 5 is closing setting, and the mandril 5 offers at least one venthole 51 on the circumference wall body on top, if
Do that type that stomata 51 can quickly make is intracavitary to pour in gas, the venthole 51 is connected to the inner cavity of mandril 5；The air pump connection is set
It sets and is located on the body of rod below lower template in mandril 5, in die sinking, gas, gas are passed through into the body of rod of mandril 5 by air pump
In the intracavitary formation ejecting force of type, moulding is ejected automatically and quickly.
The body of rod that the mandril 5 is located at 51 or more venthole is back taper cylindrical structure, the outlet of the venthole 51
The small end or position more than small end that port is provided with 5 bullet of mandril, it is recessed that the 2 type bottom of chamber face of lower template corresponds to mandril 5
There is a taper hole 52, the taper hole 52 and mandril top fixed position, when molding, the top of mandril is fitted tightly in taper hole 52, is opened
When mould, air pump 21 is first opened, as long as mandril moves up, venthole 51 and the generation of mandril pilot hole 50 gap, gas is from venthole
50 overflow, and enter in type chamber 20 behind the gap on taper hole 52 and mandril top, the gas of entrance type chamber with do not eject
Compressed between moulding, formed ejecting force, eject workpiece, and should during top plate and mandril auxiliary move up, can quickly and
Very labour-saving pushes moulding to move up demoulding, overflows from mandril pilot hole 50 to reduce gas, mandril 5 and mandril pilot hole
The sliding setting of 50 gaps, and sealing ring or piston 53 are arranged on mandril.
As shown in Fig. 5, the discharge component includes discharging guide rod 11 and spring return 12, and the lower template 2 is from upper
Pilot hole 10 is offered from lower perforation, the discharging guide rod 11 is threaded through in the pilot hole 10, and the discharging guide rod 11
Top is free end, and the bottom end of the discharging guide rod 11, which extends downwardly, to be arranged on top plate 3, and the spring return 12 is set in
On the discharging guide rod 11, and the bottom of lower template 2 is arranged in one end connection of the spring return 12, and the other end connects
It is arranged on top plate 3；In molding, pressing plate is moved down, and spring return is in tensional state, when die sinking, the spring return
12 changes to retracted state and promote top plate 3 and shift up from stretching, to eject moulding, when molding again, directly lead to
It crosses cope plate and covers and be located at die joint on the top of discharging guide rod 11 hereinafter, the top of mandril 5 is exited to bottom offset simultaneously
Type chamber 20, which is not required to manually be manually operated again, very convenient without manually retracting top plate 3, and when saving
Between.
The pilot hole 10 is counter sink from top to bottom, and the discharging guide rod 11 is T-type bar structure, and the discharging is led
Bar 11 includes the guiding body of rod 15 of integrally formed limit end 14 and smaller radial compared with major diameter, and the limit end 14 is located at institute
In the countersunk head for stating pilot hole 10；The countersunk head depth of pilot hole is equal to the height of limit end 14, and the limit of limit end 14 is unloaded
Material guide rod 11 moves down stroke, guarantees mandril 5 when moving down in place, mandril top is just bonded with 20 bottom surface of type chamber.
As shown in Figure 3 to Figure 5, it is recessed with the first installation groove 16 from top to bottom in the limit end 14, it is described
It is provided with the first magnet 13 in first installation groove 16, corresponding first installation groove 16 in the bottom surface of the cope plate 1 is recessed with the
Two installation grooves 17, the installation groove are shrinkage pool structure, are inside embedded with magnet, the aperture etc. of the second installation groove 17
In the first installation groove 16 or less than the countersunk head diameter of pilot hole, to guarantee to cover when cope plate 1 pushes in discharging
On the top of guide rod 11, guarantees that the stabilization of discharging guide rod moves down, the second magnet 18, institute are provided in second installation groove 17
The magnetic pole of the first magnet 13 and the second magnet 18 is stated on the contrary, the top surface of at least described first magnet, the 13 spacing lower template 2 is arranged, or
The bottom surface of second magnet, the 13 spacing cope plate 1 is arranged, and in molding, by the part pitch space, is avoided that the first magnetic
Iron and the contact of the second magnet, are the repulsive force slot milling of two magnet, as empty avoiding position；In die sinking, cope plate 1 is moved up,
When being displaced smaller, the repulsive force of the first magnet 13 and the second magnet 18 is still larger, and repulsive force is still greater than spring return 12
Rebound elastic force, then discharging guide rod 11 still remains stationary, when moving to the first magnet 13 and the second magnet 18 on cope plate continues
When repulsive force is less than the rebound elastic force of spring return 12, discharging guide rod 11 moves up under the action of spring return 12, top plate
It is moved up with mandril, the intracavitary moulding of mandril ejection type, ejection process terminates, which all automates, and can substantially subtract
Few manual operation, is saved the time, and improving production efficiency.Ejection process of the invention is later than the die sinking process of mold, to protect
Card within the time of this buffering, can be cooled down and be cooled down to moulding again, rather than be passed through immediately after mold die sinking
The ejection of discharging mandril, can guarantee that the cooling of moulding is more abundant, while also be more conducive to the demoulding of product.
The above is only a preferred embodiment of the present invention, it should be pointed out that: for the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also answered
It is considered as protection scope of the present invention.
