Description
Technical field
The utility model relates to a kind of injection molding machine, the knock-pin quick connection structure for injection molding machine is concretely related to.
Background technique
For falling pull-type mold, product is set to fall off by pulling force.In more mold exchange, main knock-pin inner end and top are needed
Ejecting plate, which facilitates, to be dismounted.But the disassembly and assembly structure part of existing main knock-pin and liftout plate is various, mismachining tolerance accumulation, to add
Work and installation bring biggish trouble, while more screw being needed to be fixedly connected, and increase the cost of ejection part.
Summary of the invention
Therefore, the purpose of this utility model is to provide a kind of main knock-pin and liftout plate it is convenient for disassembly and assembly be used for injection molding machine
Knock-pin quick connection structure.
What the purpose of this utility model was realized in.
A kind of knock-pin quick connection structure for injection molding machine, including ejection cylinder, piston rod, liftout plate and main knock-pin,
The piston rod inner end is mounted in ejection cylinder, and piston rod outer end is fixedly connected with ejection back, and ejection plate surface is vertical
A cylindrical body is stretched out, cylindrical body is radially equipped with pit, and pit bottom surface is located in cylindrical body body, and cylindrical body is extended in pit top surface
Side, pit is interior to be equipped with spring and positioning pin, positioning pin compressed spring in pit.
Corresponding main knock-pin inner end is along cylindrical channel is axially arranged with, and cylindrical channel inner wall surface is along main knock-pin diameter
A ball impression is formed to concaving.
When the cylindrical body insertion cylindrical channel, first positioning pin is pressed into pit, so that positioning pin top end face and circle
Column side face is concordant, after squeezing into cylindrical channel positioning pin, continues that cylindrical body is made to be inserted into cylindrical channel, positioning pin can quilt
Spring, which is squeezed into ball impression, realizes that main knock-pin is fixed with liftout plate.
The above technical solution can be further improved as follows.
The port chamfering of the cylindrical channel.
The joint face of the ball impression and cylindrical channel is inclined surface.
The utility model structure designs advantages of simple, simplifies the dismounting of main knock-pin and liftout plate, is conveniently used for pull-type
The European ejection of mold, simultaneous processing is convenient, and installation is simple.
Detailed description of the invention
Fig. 1 is embodiment decomposition texture schematic diagram.
Fig. 2 is the axial schematic cross-sectional view of main knock-pin inner end portion.
Fig. 3 is A-A cross-sectional view.
Fig. 4 is main knock-pin inner end axial sectional view.
Fig. 5 is B-B cross-sectional view.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.
Embodiment, in conjunction with attached drawing, a kind of knock-pin quick connection structure for injection molding machine, including ejection cylinder 1, piston rod 2,
Liftout plate 3 and main knock-pin 4.
2 inner end of piston rod is mounted in ejection cylinder, and 2 outer end of piston rod is fixedly connected with 3 back side of liftout plate, ejection
3 surface of plate extends perpendicularly out a cylindrical body 5, and cylindrical body 5 is radially equipped with pit 6, and 6 bottom surface of pit is located in cylindrical body body, pit
Cylindrical sides are extended in top surface, are equipped with spring 7 and positioning pin 8, positioning pin compressed spring in pit in pit 6.
Corresponding main 4 inner end of knock-pin edge is axially arranged with cylindrical channel 9, the port chamfering 10 of cylindrical channel 9, cylinder
9 inner wall surface of shape channel along main knock-pin radially-inwardly spill at a ball impression 11, the connection of ball impression 11 and cylindrical channel 9
Face is inclined surface 12.
When the cylindrical body insertion cylindrical channel, first positioning pin is pressed into pit, so that positioning pin top end face and circle
Column side face is concordant, due to the port chamfering of cylindrical channel, so that positioning pin squeezes into cylindrical channel internal ratio smoothly, continues
Cylindrical body is set to be inserted into cylindrical channel, positioning pin can be squeezed into ball impression by spring realizes that main knock-pin is fixed with liftout plate, i.e.,
Beginning positioning pin is not squeezed into ball impression in time, and main knock-pin under also only need to slightly rotating, positioning pin also enters ball impression quickly
It is interior.
When disassembly, main knock-pin only need to be rotated, makes positioning pin along pressing spring under inclined surface, makes positioning pin top end face and circle
Column side face is concordant, main knock-pin can be extracted.
