Detailed description of the invention:
Fig. 1 is top view of the invention；
Fig. 2 is partial enlarged view of the Fig. 1 about A；
Fig. 3 is cross-sectional view of the Fig. 2 along B-B.
Specific embodiment:
Embodiment is shown in as shown in Figure 1 to Figure 3, a kind of novel ejection device of miniature injection machine, the main body including injection molding machine
11, fixed form 12, more cross bars 13 and collapsible form 14, fixed form 12 are fixed on the right side of main body 11 by cross bar 13,
Collapsible form 14 is slidably connected on cross bar 12 and between main body 11 and fixed form 12；It is fixed on the fixed form 12
There is fixing mould 21, be fixed with flexible mould 22 on collapsible form 14, the left side of fixing mould 21 and the right side of flexible mould 22
End face is formed and the consistent type chamber 201 of product profile, forms the cast gate 211 communicated with type chamber 201 in the fixing mould 21,
Multiple centre holes 221 communicated with type chamber 201 are formed on flexible mould 22, the cross section of the centre hole 221 is in " work " word
Type, a thimble 23 is socketed in each centre hole 221, and the thimble 23 includes the top 231 being arranged from right to left, extension bar
232, boss 233 and mandril 234 are socketed with spring 24 on extension bar 232, and the both ends of spring 24 press up against the right side of boss 233
On the left side step surface of end face and centre hole 221, the driving chamber 141 and connect that left side is open are formed on the collapsible form 14
The through-hole 142 of logical driving chamber 141 and centre hole 221, the driving chamber 141 is interior to be equipped with several cylindrical bodies 25 and pushing block 26, cylinder
Body 25 is located at the mandril 234 of pushing block 26 and thimble 23 across the end of through-hole 142, and multiple cylindrical bodies 25 are put in pyramid
It sets, the mandril 234 of each thimble 23 is correspondingly arranged on a cylindrical body 25, and the front-end and back-end of the cylindrical body 25 are pressed against respectively
On the inner wall of driving chamber 141；The rib 142 for stopping sliding block 26 is formed on the outside inner wall of the driving chamber 141,
In slidably connect support frame 27 between two cross bars 13, support frame 27 is fixed by screws on cross bar 13, the bearing support
Top pillar 28 is fixed on 27 right side wall, the end of top pillar 28 is fixed with jacking block 29,29 face pushing block 26 of jacking block.
Further, the outer wall of the top 231 is matched with the inner wall in the right end hole of centre hole 221, top 231
Left side be pressed against on the right side step surface of centre hole 221, the right end for coming directly towards 231 flushes setting with the left side wall of type chamber 201.
Further, it is installed with guide rod 31 in the fixing mould 21, forms and be oriented on flexible mould 22
