And if the requirement using larger thrust then to equipment is higher, being unfavorable for the generalization of production.
Utility model content
In order to solve the above problems, the utility model provides a kind of spiral plastic mold：
A kind of spiral plastic mold, including body frame, piston component, feeding device, motor, pulling force pump, the body frame
Charging aperture provided with chute with the plastic film chamber for connecting mold injection, described chute one end be provided be used for control motor with
The controlling switch of pulling force pump, the piston component includes cylinder, the rotary-piston in cylinder, the discharging positioned at barrel tip
Pipe.The cylinder side is located in the chute that body frame is provided with provided with raised block, the block, and block top is provided with and feed
The corresponding charging aperture of device, the charging aperture constitutes to be provided with first passage, cylinder with cylinder inner surface provided with discharging opening to be held
Receive the cavity of rotary-piston, the rotary-piston includes the rotary power bar and cock body interfixed, and the rotary power bar connects
Motor and pulling force pump are connect, the cock body constitutes screw thread with cylinder and coordinated, and second channel, the second channel are provided with cock body
Import it is corresponding with first passage, the outlet of second channel is communicated positioned at the upper surface of cock body with discharge nozzle.The discharge nozzle
Charging aperture with body frame is corresponding.
It is preferred that, being provided between the chute and block is used to make the elastic component that block is inwardly moved.
It is preferred that, the elastic component is spring.
Beneficial effect：Greatly reduced by way of being threadingly advanced, the propulsive force that pulling force pump needs so that before cock body
Enter to tend towards stability, and increase the pressure of plastic film intracavitary so that the die quality of injection is more preferably.
Brief description of the drawings
Accompanying drawing 1 is the view of charging flow.
Accompanying drawing 2 is the first state figure of discharging flow.
Accompanying drawing 3 is the second state diagram of discharging flow.
Embodiment
The utility model is further described with embodiment below in conjunction with the accompanying drawings.
A kind of spiral plastic mold, including body frame 1, piston component, feeding device 3,
The body frame 1 is provided with chute and the charging aperture of the plastic film chamber 6 for connecting mold injection, and described chute one end is provided with
Controlling switch 7 for controlling motor 4 and pulling force pump 5.
The piston component includes cylinder 8, the rotary-piston 9 in cylinder 8, the discharge nozzle 10 positioned at the end of cylinder 8.
The side of cylinder 8 is located in the chute that body frame 1 is provided with provided with raised block 11, the block 11, the chute and block
Being provided between 11 is used to make the elastic component 2 that block 11 is inwardly moved, and the elastic component 2 is spring, adds piston component inside
Pressure, it is to avoid cause material to overflow because pressure is excessive during charging, improve sealing.
The top of block 11 is provided with the charging aperture corresponding with feeding device 3, and the charging aperture is provided with out with the inner surface of cylinder 8
Material mouth is constituted provided with the cavity for accommodating rotary-piston 9 in first passage 12, cylinder 8, and the rotary-piston 9 includes what is interfixed
Rotary power bar 13 and cock body 14, the connection motor 4 of rotary power bar 13 and pulling force pump 5, the cock body 14 and cylinder 8
Constitute screw thread to coordinate, second channel 15 is provided with cock body 14, the import of the second channel 15 is corresponding with first passage 12, the
The outlet of two passages 15 is communicated positioned at the upper surface of cock body 14 with discharge nozzle 10.The charging aperture phase of the discharge nozzle 10 and body frame 1
Correspondence.
The direction that body frame 1 is inserted in direction for piston component is moved inward described in this patent.
Feed state (such as Fig. 1)：Start the reversion that rotary drive motor 4 controls rotary-piston 9 so that the phase of rotary-piston 9
Cylinder 8 is rotated and is displaced outwardly so that rotary-piston 9 is moved out to the bottom of cavity, the control piston component of pulling force pump 5
Move out, now first passage 12 is mutually butted with the second channel 15, material enters in cavity.
The first state (such as Fig. 2) of discharge state：When material is full of in cavity, the control piston component of pulling force pump 5 is inside
Motion, due to rotary-piston 9 and the composition screw thread cooperation of cylinder 8, during rotary-piston 9 is moved, rotary-piston 9 and cylinder
8 are relatively fixed, therefore the capacity of cavity remains constant, and after discharge nozzle 10 inserts the charging aperture of body frame 1, block 11 is pressed
In controlling switch 7.
The second state (such as Fig. 3) of discharge state：Controlling switch 7 stops pulling force pump 5, starts motor 4, so as to control
The rotating forward of rotary-piston 9, now piston relative to cylinder 8 rotation move inward, the material in compaction cavum enter body frame 1 mold
Intracavitary, completes plastic film.
Obviously, above-described embodiment of the present utility model is merely to illustrate that the utility model example, and not
Restriction to embodiment of the present utility model.For those of ordinary skill in the field, on the basis of described above
On can also make other various forms of changes or variation.There is no need and unable to give poor example to all embodiments.
And these belong to the obvious changes or variations that connotation of the present utility model amplifies out and still fall within the utility model
Protection domain.
