Abstract
The utility model discloses a kind of sliding blocks to twist dental strip arc core-pulling mold, including moving template, hydraulic motor, mekydro, fuse gear, strand tooth fuse, circular arc sliding block, circular arc fuse, sliding block gear, rack gear, oil cylinder；The hydraulic motor is mounted on moving template, mekydro is fixedly attached on the output shaft of hydraulic motor, mekydro is engaged with fuse gear, fuse gear, which is fixedly attached to, twists in the middle part of tooth fuse that circular arc sliding block is swingable is mounted on moving template, the inner end of circular arc sliding block is fixed with circular arc fuse, gear ring in circular arc sliding block outer rim is engaged with sliding block gear, the engagement of sliding block wheel and rack, one end of rack gear and the output axis connection of oil cylinder.Since the hydraulic motor of the utility model twists the rotation of tooth fuse by mekydro, the driving of fuse gear, complete the core pulling of product thread, oil cylinder completes core pulling by rack gear, sliding block gear, circular arc slider-actuated circular arc fuse, and mold is more convenient in use, is safer.
Description
Technical field
The utility model relates to a kind of injection molds, twist dental strip arc core-pulling mold more particularly to a kind of sliding block.
Background technique
Plastic injection mould is the tool for producing plastic products, very widely used.In plastic products injection moulding, by
There is internal screw thread in certain plastic products, plastic part is needed after shaping with paying tooth motor, drive sprocket, chain, central spindle gear
Deviate from from the internal screw thread of plastic products Deng by the central spindle gear as type core.This debentition mode commonly used is due to central spindle gear
It can dally when entering type chamber every time, can slightly have difference into the position of type chamber, the start-stop of the internal screw thread for the plastic products being molded by
Point position cannot also be consistent, product it is second-rate.
Summary of the invention
The purpose of this utility model is to provide a kind of sliding blocks easy to use, safe to twist dental strip arc core-pulling mold.
To achieve the above object, the technical solution of the utility model is:
The utility model is that a kind of sliding block twists dental strip arc core-pulling mold, including moving template, hydraulic motor, mekydro,
Fuse gear twists tooth fuse, circular arc sliding block, circular arc fuse, sliding block gear, rack gear, oil cylinder；The hydraulic motor is mounted on dynamic
In template, mekydro is fixedly attached on the output shaft of hydraulic motor, and mekydro is engaged with fuse gear, and fuse gear is solid
Surely be socketed in twist tooth fuse in the middle part of, twist tooth fuse be rotatably mounted on moving template, twist tooth fuse inner end have screw thread and
Protrude into type chamber；The circular arc sliding block is swingable to be mounted on moving template, and the inner end of circular arc sliding block is fixed with circular arc fuse, circle
Gear ring is studded in the outer rim of arc sliding block, which engages with sliding block gear, the engagement of sliding block wheel and rack, one end of rack gear and oil
The output axis connection of cylinder.
The fuse gear, twist tooth fuse, circular arc sliding block, circular arc fuse, sliding block gear all there are two.
After adopting the above scheme, since the utility model includes moving template, hydraulic motor, mekydro, fuse gear, twists
Tooth fuse, circular arc sliding block, circular arc fuse, sliding block gear, rack gear, oil cylinder, hydraulic motor are driven by mekydro, fuse gear
The rotation of tooth fuse is twisted, tooth moves back in Jiao Ya mechanism, completes the core pulling of product thread, and oil cylinder is driven by rack gear, sliding block gear, circular arc sliding block
Dynamic circular arc fuse completes core pulling, preferably resolves problem of misalignment when twisting tooth and the molding of circular arc slipper block loose core, effectively prevents twisting
For tooth in rotation, the specified rotation of fuse is in specified angle and position, and the problem of burn failure is even scrapped, mold is using
It is more convenient in the process, is safer, and not limited by rotational angle or position.

Specific embodiment
As shown in Figure 1, Figure 2, Figure 5, the utility model is that a kind of sliding block twists dental strip arc core-pulling mold, including moving template 1,
Hydraulic motor 2, mekydro 3, fuse gear 4, twist tooth fuse 5, circular arc sliding block 6, circular arc fuse 7, sliding block gear 8, rack gear 9,
Oil cylinder 10.
The hydraulic motor 2 is mounted on moving template 1, and mekydro 3 is fixedly attached to the output shaft of hydraulic motor 2
On, mekydro 3 is engaged with fuse gear 4, and fuse gear 4, which is fixedly attached to, twists 5 middle part of tooth fuse, and it is rotatable to twist tooth fuse 5
Be mounted on moving template 1, the inner end for twisting tooth fuse 5, which has, screw thread and protrudes into type chamber；The swingable peace of the circular arc sliding block 6
On moving template 1, the inner end of circular arc sliding block 6 is fixed with circular arc fuse 7, gear ring 61 is studded in the outer rim of circular arc sliding block 6, the tooth
Circle 61 is engaged with sliding block gear 8, and sliding block gear 8 is engaged with rack gear 9, one end of rack gear 9 and the output axis connection of oil cylinder 10.
In the present embodiment, the fuse gear 4, strand tooth fuse 5, circular arc sliding block 6, circular arc fuse 7, sliding block gear 8
There are two all.Two strand tooth fuses 5 are symmetrical arranged, be socketed in the fuse gear 4 twisted on tooth fuse 5 be also symmetrical arranged and all with liquid
Knob wheel 3 engages；Two circular arc sliding blocks 6 are symmetrical arranged, and are also symmetrically set with the sliding block gear 8 that two circular arc sliding blocks 6 engage respectively
It sets and is engaged respectively with the two sides of rack gear 9.
Working principle of the utility model is:
1, it as shown in Fig. 2, when mold is opened first, is opened in solid plate and moving template 1, it is sliding under the action of inclined guide pillar
Block is detached from injecting products and is detached from product completion die sinking for the first time.
2, as shown in figure 3, hydraulic motor 2 starts turning, the rotation of mekydro 3 twists tooth fuse 5 and rotates, and twists 5 tail of tooth fuse
Portion has one, and with front end, for identical tooth away from twisting in spiral shell, mold is installing a fixture nut matched.To which upper makes strand tooth fuse 5
It retreats, completes second and be opened.
3, as shown in figure 4, oil cylinder 10 starts to act, rack gear 9 drives circular arc sliding block 6 to swing, and completes third time and is opened.Finally
Complete product ejection.
The above, only the utility model preferred embodiment, therefore the utility model implementation cannot be limited with this
Range should still belong to this reality that is, according to equivalent changes and modifications made by present utility model application the scope of the patents and description
In the range of being covered with new patent.
