Detailed Description

The utility model provides a dustproof protection architecture of high reliability mould.

Referring to fig. 1-2, fig. 1 is a schematic view of an overall three-dimensional structure according to an embodiment of the present invention, and fig. 2 is a schematic view of an overall front structure according to an embodiment of the present invention.

As shown in fig. 1, in the embodiment of the present invention, the dustproof protection structure of the high reliability mold includes: the fixed die mounting plate 100, the fixed die plate 200, the movable die plate 300, the support plate 400 and the movable die mounting plate 500 are sequentially arranged from top to bottom, an accommodating cavity 410 which is through up and down is arranged in the support plate 400, and an ejecting device used for ejecting a molded product is arranged in the accommodating cavity 410. The ejection device includes: an ejector seat plate 600, an ejector plate 700 provided on the ejector seat plate 600, and an ejector 710 provided on the ejector plate 700. The ejector pin base plate 600 moves up and down together with the ejector pin plate 700 in the accommodating cavity 410 to drive the ejector pins 710 to move, so that the plastic product formed in the mold forming cavity is ejected after the mold is opened.

An opening communicated with the accommodating cavity 410 is formed in one side wall of the supporting plate 400, a sunken step 411 is arranged at the opening of the opening, and a transparent dust-proof plate 800 is fixed in the step 411 through a screw.

Through setting up sunken step 411 at open-ended oral area to in passing through screw fixation step 411 with transparent dust guard 800, make transparent dust guard 800 can not exceed backup pad 400 and increase the volume of mould, simultaneously, make the whole area of transparent dust guard 800 be greater than the area of opening main part, and then make transparent dust guard 800's dustproof effect better.

Transparent dust guard 800 can effectively prevent impurity such as dust and iron fillings from entering into and holding in the chamber 410 to improved the ejecting precision of thimble board 700 and the size precision of injection moulding product, prolonged the use of mould and suffered from, the problem emergence that the ejecting device that significantly reduces bruised the mould part. The transparent dustproof plate 800 is arranged, so that the working condition of the ejection device can be observed in real time, and the operation of adding lubricating oil to the ejection device can be realized by disassembling the transparent dustproof plate 800.

Specifically, in the present embodiment, in order to prevent the interference with the inner wall of the transparent dust-proof plate 800 when the ejection device moves, a gap of 2mm is provided between the inner wall of the transparent dust-proof plate 800 and the side wall of the ejection device. In order to facilitate the assembly and disassembly of the transparent dust-proof plate 800, a gap of 0.5mm is formed between the outer peripheral side wall of the transparent dust-proof plate 800 and the inner peripheral side wall of the step 411.

Be equipped with the electronic switch who is used for detecting whether ejecting device resets completely on ejecting device, electronic switch includes: an induction adjusting block 910 and an induction switch 920 in induction cooperation with the induction adjusting block 910.

When the ejection device is reset, the induction adjusting block 910 moves downwards along with the ejection device, when the induction adjusting block 910 moves to be in induction fit with the induction switch 920, the ejection device is completely reset, the induction switch 920 sends a production signal to an external control system of the injection molding machine through a signal line, and the external control system of the injection molding machine controls the injection molding machine to close the mold and inject the glue for production. When the ejection device is blocked in the resetting process, the induction matching cannot occur due to the fact that the induction adjusting block 910 is far away from the induction switch 920, the induction switch 920 cannot send a production signal to a control system of an external injection molding machine, the control system of the external injection molding machine cannot control the injection molding machine to carry out die assembly and injection production due to the fact that the production signal cannot be received, and therefore die damage caused by forced die assembly when the ejection device is blocked is prevented.

Whether the ejection device is completely reset or not can be monitored by arranging the electronic switch on the ejection device, so that the damage to a mold caused by forced mold closing of the injection molding machine when the ejection device is blocked is prevented.

Transparent dust guard 800 is provided with U-shaped through hole 810 aligned with electronic switch, and thimble seat board 600 and thimble board 700's lateral wall are provided with the caulking groove aligned with U-shaped through hole 810, and electronic switch's response regulating block 910 sets up in the caulking groove.

Through set up U type through-hole 810 on transparent dust guard 800, can realize under the condition of not tearing open the dust guard, adjust electronic switch device, save time increases work efficiency.

The technical scheme of the utility model through setting up transparent dust guard 800 and electronic switch, realize duplicate protection, improved the reliability of the dustproof protection architecture of mould greatly.

The above only be the preferred embodiment of the utility model discloses a not consequently restriction the utility model discloses a patent range, all are in the utility model discloses a conceive, utilize the equivalent structure transform of what the content was done in the description and the attached drawing, or direct/indirect application all is included in other relevant technical field the utility model discloses a patent protection within range.
