Power pull bar 4 and opening-closing controller 5.Wherein, angled-lift splits constitutes mould product by bindiny mechanism and stroke shifting block gap slide fit
Moulding section, its making material and processing fit precision require very high, and making material is needed to meet plastic rubber shaping needs, and processing is matched somebody with somebody
Closing precision needs to meet gap slide fit.
And stroke shifting block, power lever and opening-closing controller constitute power transfer part, the stroke shifting block is led with guiding
Rail component movement targeting part；The stroke shifting block is provided with the one end for installing shutter in guiding rail, and guiding is led
Rail coordinates for gap stroke shifting block mating surface, plays a part of positioning and vertically-guided to stroke shifting block.Wherein shutter
Frictional force will can meet the pulling force needs of pull bar.Wherein each part has relative motion, wherein angled-lift splits and row each other
Moved between journey shifting block for gap slide fit, be gap slide fit within movement clearance 0.01~0.02, between stroke shifting block and guide rail
Motion, movement clearance 0.01~0.02 is interference fitted, movement clearance minus 0.02 between power lever and shutter for fricting movement
~minus 0.05.
Wherein, angled-lift splits is the part that plastic cement products shape is molded, mainly device inside die and stroke shifting block group
It is combined and uses.By dovetail groove precision-fit and guiding between them, the Steel material that it makes is according to different moulding plasticses
To determine, mainly there are the die steels such as S136, SKD61 and NAK80, its rake angle typically does 5~10 °, and the angle of dovetail groove is done
25 ° of thickness 3mm.
Stroke shifting block is the part of forming plastic cement shape of product and control angled-lift splits action, and mainly device is inside die
It is used in combination with through solid plate, and angled-lift splits, guide rail, opening-closing controller.Mainly pass through dovetail groove with angled-lift splits
Precision-fit and guiding, its Steel material made determine mainly there is S136, SKD61 and NAK80 etc. according to different moulding plasticses
Die steel, its rake angle typically does 5~10 °, and the angle of dovetail groove is 25 ° of thickness 3mm；Want and guide rail in 4 faces of its four side
Coordinate and slide, machining accuracy needs to reach negative 0.005mm；Top surface needs to process M6 metric system thread and the locating slot of shutter；
Need design to protrude 3.5mm in this side for having dovetail groove and do spacing positioning action in this mechanism kinematic.
Guiding rail is the guide effect in slide fit motion of stroke shifting block, and its making material bronze or graphite brass are multiple
Condensation material, the machining tolerance in intermediate tie hole needs to accomplish zero~just 0.01mm, and 4 outsides are also required to accurate processing, tolerance control
Make positive and negative 0.01mm.
Power lever is pulling force drive disk assembly, and main and stroke shifting block, shutter are used in combination, and utilize injection machine
The power produced during die sinking matched moulds is delivered on stroke shifting block by shutter linking, and it is arranged on mold fixed plate, relatively
It is fixed part, making material 718HH for mould.
Opening-closing controller is linking pull bar and the part of stroke shifting block, plays a part of transmission pulling force and switch, its is main
The special nylon of the making material of workpiece, a diameter of 13mm of size, it is produced mainly by being rubbed between pulling force pull bar
Frictional force, can within 150 °C at a high temperature of use, single shutter can bear below 65k g pulling force.
Case study on implementation part of the present invention is as shown in figure 1, be product of the injection molding with the interior button demoulding.
It can show on the inside of product there is 4 depanning back-offs in figure, back-off core pulling goes out in cover half.And can be for design
The space of mould structure is very narrow and small, and space is too small for common fixed mould lifter structure, and bad to design and produce, intensity compares
Weak, performance is unstable.And the small-sized inner core pulling slide block mechanism that similar feature can be provided using the present embodiment is light
Solve.
Case study on implementation part of the present invention is as shown in Fig. 2 be arranged on the position situation of product for mechanism of the present invention.
Four small-sized inner core pulling tripping mechanisms install and use situation on injecting products, and each is independently installed makes
With it can be seen that the space of mechanism of the present invention occupancy is very small from picture, use is very rationally exquisite.We are current for this mechanism
More than 20 sets are used on mould.
Case study on implementation part of the present invention is as shown in figure 3, be mechanism working condition of the present invention
3 prevailing operating state rightmosts of mechanism are the working conditions that mould closes this mechanism；Centre is that mould was molded
The working condition of this mechanism of journey；The left side is the working condition of this mechanism after mould is opened completely.
Case study on implementation part of the present invention is as shown in figure 4, be the small-sized detailed operating principle of inner core pulling slide block mechanism
First, mould pull bar and shutter in firm die sinking is locked together, and pulls shifting block to move upwards, shifting block passes through oblique dovetail groove
Mechanism drives angled-lift splits to left movement, so as to depart from shaping back-off.
Secondly, blocked when the confined planes of shifting block encounter guide rail by guide rail with regard to stop motion, shaping back-off is also complete
Depart from；Then mould continues to die sinking, and now shutter is opened, and pull bar and shifting block separation, shifting block and angled-lift splits keep coordinating
This core-pulling mechanism repeats identical action continuation production after the completion of stop motion under situation, a cycle.
In addition to the implementation, the present invention can also have other embodiment.All use equivalent substitution or equivalent transformation shape
Into technical scheme, all fall within the protection domain of application claims.
