Specific embodiment
The demoulding of T3 features use circular arc slipper block loose core+Angle Pin slider-actuated mechanism, mechanism assembly include part 21~
36, as shown in F-F section views in Fig. 1；Mechanism can be divided into two parts, and Part I is T3 feature demoulding core pulling executive modules, bag
Include part 21~28；Part II is drive mechanism component, including part 29~36.With reference to shown in figure below Fig. 2, executive module
Structural principle is：T3 circular arcs sliding block shaping mold insert 25 is the shaping mold insert of T3 features, and it passes through screw and is fastened on T3 circular arcs
On sliding block 26, and T3 circular arcs sliding block 26 is fastened on T3 circular arc sliding blocks base 24 also through screw, T3 circular arc sliding block bases
24 is fan-shaped moving block, and its center of rotation is the O points shown in Fig. 2, the i.e. center line of rotary middle spindle 23, is rubbed to reduce rotation
Wipe, T3 circular arc sliding blocks base 24 is provided with plane bearing 22 on O point mandrels, and by bearing backing plate 21 and T3 circular arc sliding block bases
Top board 28 is mounted；The demoulding of T3 features needs T3 circular arc sliding blocks base 24 to drive T3 circular arcs sliding block 26 around O points along circular arc
Stripping direction rotates 75 ° of complete demouldings of ability.Part II is that drive mechanism is that universal Angle Pin drives slide block movement mechanism,
When molding, sliding block Angle Pin 31 is driven to drive T3 to drive sliding block 32 to do K1 side in Fig. 2 by the T3 that is installed on impression bolster 5
To shown linear motion, T3 drives sliding block 32 to drive T3 circular arc sliding blocks base 24 to do direction shown in R1 around O points by pull bar 29
Circular-rotation, installation of the pull bar 29 on two slide bodies uses cottered joint mode, there is certain rotational freedom.
T4 features core-pulling mechanism uses slide body floating+Angle Pin flip-over type frame mode, and two effects are played by mechanism, its
One is the demoulding for realizing T4 features, secondly assisting product ejecting mechanism push rod that product is ejected completely from die cavity mold insert 4 jointly
The demoulding.T4 mechanism assemblies include 37~47.T4 sliding block pushers mold insert 37 is installed on T4 sliding blocks seat board 43 by screw, T4 sliding blocks
39 are installed on T4 sliding blocks seat board 43 by T4 slider layerings 42, and T4 sliding blocks seat board 43 is arranged at set by core fixing plate 7
It is connectionless with core fixing plate 7 in groove, can be moved up and down along die sinking direction, but T4 sliding blocks seat board 43 passes through base push rod 47
It is connected with thimble panel 12, thimble panel 12 can be moved up and down by the driving T4 sliding blocks of base push rod 47 seat board 43, and base is pushed away
Bar 47 is oriented to by the push rod guide pin bushing 45 being installed on core fixing plate 7, and T4 sliding blocks Angle Pin 44 is pressed by guide pillar pressing plate 46
Tight upside-down mounting is on core fixing plate 7.
During real work, its motion operation principle is as follows：
When product is ejected, thimble panel 12 promotes thimble 65 and base push rod 47, and direction ejects upwards shown in K2 along Fig. 2, base
Push rod 47 is ejected upwards by promoting T4 sliding blocks seat board 43, and in ejection process, T4 sliding blocks Angle Pin 44 drives T4 sliding blocks 39 along Fig. 2
Middle K3 directions are moved out, and product is then blocked by T4 sliding block pushers mold insert 37, it is impossible to motion is followed, so as to can guarantee that T4 sliding blocks
First 38 extract out from product, realize the demoulding of T4 features.So, the function of T4 feature core-pulling mechanisms has accomplished that thimble can be cooperateed with
65 eject product from die cavity mold insert 4, and the demoulding of T4 features can be completed again.
Instant invention overcomes the design difficulty of some shape certain modulis tool, for being all with reference to product for automatic core-pulling mechanism
The special demoulding of product needs and designs, and the driving of mould emptier need to borrow the function elements such as extra oil cylinder to perform, and be unfavorable for
The reduction of die structure size and the reduction of cost of manufacture, thus, preferable mode is that the mould opening force by mould in itself comes real
Now the function of each side core-pulling mechanism, quasi-step matrix gun-simulation gun stock injection moulding special construction demoulding needs, devise product note
Mould by mould machine mould opening force just can the fully automated demoulding mechanism, join for the design of comparable product provides design
Examine, as a means of discussion.
Specific embodiment described herein is only the technology neck belonging to the present invention to the present invention spiritual explanation for example
The technical staff in domain can be made various modifications or supplement to described specific embodiment or be replaced using similar mode
Generation, but without departing from spirit of the invention or surmount scope defined in appended claims.
