Description
Technical field
The invention belongs to injection machine field, and in particular to a kind of secondary slide block mechanism for the demoulding.
Background technology
In injection mold, inclined zigzag product is most difficult to injection, because dynamic model and cover half are during matched moulds,
The part for always having product is embedded in cover half, relies solely on the pulling force of unidirectional dynamic model, it is impossible to complete Z-shaped injecting products
The demoulding, if forced stripper mechanism, it is more likely that can damage die cavity, or deform upon product.
Even if inclined zigzag product is firmly forced pull-out in addition, other devices are subsequently also carried out, to sprue
Waste material sheared, the technique of multiple steps is sufficiently complex.
The content of the invention
For deficiency of the prior art, the present invention provides a kind of existing to solve for the secondary slide block mechanism of the demoulding
Injection machine cannot complete the demoulding of inclined zigzag product, stripping result is poor, the complicated problem of subsequent technique.
The present invention is achieved through the following technical solutions.

Block, described mould emptier includes mounting seat, and cam is provided with described mounting seat, and the two ends of described cam are fixed with
Nut, is additionally provided with described dynamic model and cover half and borrows mechanism, and the described mechanism that borrows is made up of sliding block and slideway two parts,
Push pedal is additionally provided with described dynamic model, described push pedal is driven by independent control system, and use is provided with described push pedal
In the ejector pin mechanism that sprue waste material is discharged, described ejector pin mechanism is made up of push rod, expansion link and thimble.For special
Zigzag moulding, devises mould emptier and borrows mechanism, forms secondary slide block mechanism, completes Internal mold release and shear action,
Production efficiency is greatly improved, cam turns around after the completion demoulding, automatically restores to original position.
Preferably, the center line of the rake of the center line of the cam of described mould emptier and moulding is with always
On line.Facilitate force on the same line, being capable of the smoothly demoulding.
Preferably, the described sliding block for borrowing mechanism is slided in slideway.The sliding block of script is close to moulding side,
Die cavity is formed, when the demoulding is needed, the sliding block of mechanism is borrowed to two Slideslips, facilitates moulding to rotate.
Preferably, being provided with cushion on the protuberance of described cam.Cushion has certain protective effect, prevents
Stop loss bad moulding.
Preferably, described control system includes guide rail, driving dolly, described driving are provided with described guide rail
Dolly is fixedly connected with push pedal.Forward backway can be controlled at any time.
Preferably, being additionally provided with push rod in described push pedal.Push rod is to prevent some postrotational zigzags to be molded
During part drops, because the angle that drops is cunning, it is stuck, push rod can smoothly allow it to drop.
Preferably, described dynamic model is driven by hydraulic stem.
Preferably, the diameter with diameter greater than thimble of described expansion link, less than the diameter on the left of sprue waste material.Stretch
Contracting bar can automatic telescopic, material can be taken off so that the sprue waste material on thimble drops originally.
Compared with prior art：To inclined zigzag moulding, mould emptier cooperates with mechanism is borrowed, and completes de-
The process of mould and shearing waste material, greatly improves efficiency and product quality.

Specific embodiment
Below in conjunction with the accompanying drawings with specific embodiment, the present invention is described further.
A kind of secondary slide block mechanism for the demoulding, including body 8, cover half 2 and dynamic model 5 are provided with described body 8,
Inclined zigzag die cavity is formed after described cover half 2 and the matched moulds of dynamic model 5, zigzag die cavity is injection molded with by injecting head 1
It is provided with mould emptier 9 in plastic 3 and sprue waste material 31, described cover half 2 and dynamic model 5, the front end of described mould emptier 9
Slidable block is provided with, described mould emptier 9 includes mounting seat 91, cam 92 is provided with described mounting seat 91,
The two ends of described cam 92 are fixed with nut 93, are additionally provided with described dynamic model 5 and cover half 2 and borrow mechanism 51, described
Borrow mechanism 51 to be made up of sliding block and slideway two parts, push pedal 6 is additionally provided with described dynamic model 5, described push pedal 6 is by independence
Control system 4 drive, the ejector pin mechanism for sprue waste material 31 to be discharged, described top are provided with described push pedal 6
Pin mechanism is made up of push rod 11, expansion link 111 and thimble 112, the center line and moulding of the cam 92 of described mould emptier 9
On the same line, the described sliding block for borrowing mechanism 51 is slided the center line of 3 rake in slideway, described cam 92
Protuberance on be provided with cushion 94, described control system 4 includes guide rail, and driving dolly is provided with described guide rail,
Described driving dolly is fixedly connected with push pedal 6, and push rod 10 is additionally provided with described push pedal 6, and described dynamic model 5 is by hydraulic stem
7 drive, the diameter with diameter greater than thimble 112 of described expansion link 111, less than the diameter in the left side of sprue waste material 31.
In use, injecting head 1 is filled with the liquid plastic of molten condition, liquid to the cover half 2 and dynamic model 5 after matched moulds
Plastics form moulding 3 and sprue waste material 31 in cooling procedure.
After completing injection cooling, the block movement of the front end of mould emptier 9 drives dynamic to the headspace of cam 92, hydraulic stem 7
Mould 5 is moved rearwards by, and is separated with cover half 2, and in fallback procedures, moulding 3 is close to cover half 2 trend together drawn back, now fixed
Start simultaneously with the mould emptier 9 in dynamic model 5 in mould 2, the inside of cam 92 in mould emptier 9 is equipped with wheel hub motor, can be certainly
Row is rotated, after the cushion 94 on the protuberance of cam 92 is contacted with the rake of moulding 3, to the rake of moulding 3
Produce the effect of power.
The sliding block for borrowing mechanism 51 blocks the formation die cavity of moulding 3 originally, now due to needing to complete shearing, borrows
The sliding block of mechanism 51 vacates position to two Slideslips, accommodates the moulding 3 in rotary course.
Moulding 3 revolves counterclockwise in the presence of the power of the cam 92 at two ends along the left side end points of sprue waste material 31
Turn, in the presence of rotational shear, sprue waste material 31 and the cut-out of moulding 3 are separated.
As dynamic model 2 continues to draw back, the blanking of moulding 3 of cut-out is fallen in the blanking basket for setting originally, this time control
System processed 4 drives push pedal 6 to move ahead forward, the position alignment sprue waste material 31 of push rod 11, during moving ahead, the material of thimble 112
It is diamond, it is very hard, the left side end points of sprue waste material 31 is inserted into, after insertion, push rod 11 is retreated backward, runner waste material
31 are extracted, and suitable clear position is backed to together, and expansion link 111 extends, because expansion link 111 is with diameter greater than thimble
112 diameter, less than the diameter in the left side of sprue waste material 31, therefore can utilize thrust runner waste material 31 from thimble 112
Release, drop in blanking basket.
Control system 4 in the present embodiment, using guide rail and driving dolly, drives dolly to be fixedly connected with push pedal 6, drives
When dynamic dolly is moved on guide rail, drive push pedal 6 to advance or retreat, but be not limited to this kind of mode, can individually connect gas
Cylinder or hydraulic cylinder.
Protection scope of the present invention includes but is not limited to embodiment of above, and protection scope of the present invention is with claims
Be defined, any replacement being readily apparent that to those skilled in the art that this technology is made, deformation, improvement each fall within it is of the invention
Protection domain.
