Specific implementation mode
The utility model is illustrated below in conjunction with the accompanying drawings.
Fig. 1-4 is a kind of embodiment of the utility model, includes bottom plate 1, lower thimble supporting plate 2, lower top successively from bottom to up
Needle plate 3, upper thimble supporting plate 4, upper ejector retainner plate 5 and lower template 6 are fixed with vertical lower thimble 31, institute on the lower ejector retainner plate 3
It states and is fixed with vertical upper thimble 51 on ejector retainner plate 5；When original state, i.e., before injection moulding process to ejection acts, upper thimble
51 and lower thimble top pass through lower template, be located at product in（The different components on identical product are shown in figure, and it is non-multi
A different product）.
The lower thimble supporting plate 2, lower ejector retainner plate 3, upper thimble supporting plate 4 and upper ejector retainner plate 5 are set in same caging bolt 7
On, the top of the caging bolt 7 is fixed in ejector retainner plate 5, and the bottom of the caging bolt 7 is actively installed on lower thimble supporting plate
In 2；The limit spring 8 being set on caging bolt 7 is additionally provided between the lower ejector retainner plate 3 and upper thimble supporting plate 4；
The top surface of the lower thimble supporting plate 2 is fixed with the bottom surface of lower ejector retainner plate 3 and is contacted, the top surface of the upper thimble supporting plate 4
It fixes and contacts with the bottom surface of upper ejector retainner plate 5, there are distance, the upper ejector retainner plates between the lower ejector retainner plate 3 and upper thimble supporting plate 4
There are distances between 5 and lower template 6；
It is additionally provided with resetting spring 10 between the lower ejector retainner plate 3 and lower template 6.
The lower section of the lower thimble supporting plate 2 is equipped with the driving device of several mandrils and mandril（Driving device is cylinder or oil
Cylinder）, the bottom plate 1 be equipped with mandril by through-hole 11.
The lower thimble supporting plate 2, lower ejector retainner plate 3, upper thimble supporting plate 4 and upper ejector retainner plate 5 are also movably set in same limit
On column 9, the top of the limited post 9 is contacted with the bottom surface of lower template 6, and the bottom of the limited post 9 is bolted on bottom
On plate 1.7 scattering device of limited post 9 and caging bolt, it is ensured that lower thimble supporting plate 2, lower ejector retainner plate 3, upper thimble supporting plate 4 and upper top
Needle plate 5 during the motion will not moving offset, to ensure ejection action it is precise and stable.
The lower thimble supporting plate 2 is equipped with the notch cuttype through hole 21 for accommodating caging bolt 7, the bottom card of the caging bolt 7
On the ladder of notch cuttype through hole 21.When realizing that resetting spring drives lower thimble supporting plate and lower thimble sheet reset, lower jacking plate energy
It is enough to pull upper ejector retainner plate and upper thimble sheet reset（I.e. so that spacing out between upper ejector retainner plate and lower template）, so as to next time
Eject work.
The working process of the utility model is as follows：After the completion of injection molding, panel 103, water gap plate 102 and cope plate 101 are removed, is produced
Grade is in lower template 6（As shown in Figure 2）, start the driving device of mandril, make it that mandril be driven to move upwards, mandril passes through logical
Hole 11 resists lower thimble supporting plate 2, drives lower thimble supporting plate 2 and lower ejector retainner plate 3 to move upwards, limit spring 8 is compressed, the pressure
Upper thimble supporting plate 4 and upper ejector retainner plate 5 are pushed up upwards, therefore start initial, lower thimble supporting plate 2, lower ejector retainner plate 3, upper thimble in mandril
Supporting plate 4 and upper ejector retainner plate 5 almost synchronize move upwards, entire product is ejected lower template 6 by lower thimble 31 and upper thimble 51（Such as figure
Shown in 3）, when upper ejector retainner plate 5 touches lower template 6,51 stop motion of upper thimble supporting plate 4, upper ejector retainner plate 5 and upper thimble, top
Bar continues upwards to push up lower thimble supporting plate 2, lower ejector retainner plate 3 and lower thimble 31, and lower thimble 31 drives product to continue uplink so that production
Product are detached with upper thimble 51（As shown in Figure 4）, so that product falls or conveniently removes automatically；After product is removed, mandril
Driving device drives mandril downlink, and lower thimble supporting plate 2 is without the active force pushed up upwards, the compressed reset during uplink
Spring 10 and limit spring 8 lose external force, and reset condition to be restored to, during this, limit spring 8 makes 3 He of lower ejector retainner plate
Lower thimble supporting plate 4 spaces out, and resetting spring 10 drives lower thimble supporting plate 2, lower ejector retainner plate 3 and lower thimble 31 to move downward, and waits for
After limit spring 8 is in non-compressed state, continues the lower thimble supporting plate 2 moved downward and lower ejector retainner plate 31 can be to limit spring 8
Generate pulling force so that limit spring 8 pulls down upper thimble supporting plate 4 and upper ejector retainner plate 5 so that upper ejector retainner plate 5 and lower template 6 it
Between space out, until lower thimble supporting plate touches bottom plate, homing action terminates.
The utility model is simplified mould structure, is shortened the manufacturing cycle of mold, carried by the innovative design to mould structure
Rise the structural stability of the quality and mold of product.
