Specific embodiment
The utility model is further described 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 combined plastic table supporting frame, packet
Cope plate 1, lower template 2, top plate 3, mandril 5 and discharge component are included, the cope plate 1 is opened by guide post 6 relative to lower template
Molding setting, the lower section of lower template 2 is arranged in 3 spacing of top plate, and the top plate 3 is set relative to lower template up and down displacements
It sets, several mandrils 5 is vertically installed on the top plate 3, the top activity of the mandril 5 passes through lower template 2 and protrudes into lower template
Type chamber 20 in, when molding, 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 on, the discharge component is promoted under opening and closing mould state or lower coping 3, in molding, under mandril 5 and mandril 3
It is depressed into initial position, is opened after injection molding, the top plate 3 shifts up automatically by discharge component and ejects injection molding
Part, the process reduce artificial participation, save time, raising efficiency, while mitigating labor intensity.
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.The ejection process of the utility model is later than the die sinking process of mold,
To guarantee, after mold die sinking, within the time of this buffering, can moulding be cooled down and be cooled down again, rather than immediately
It is ejected by discharging mandril, can guarantee that the cooling of moulding is more abundant, while being also more conducive to the demoulding of product.
The above is only the preferred embodiment of the utility model, it should be pointed out that: for the common skill of the art
For art personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these improve and
Retouching also should be regarded as the protection scope of the utility model.
