Abstract

A die device for a gear of a paper turning device of a printer comprises a fixed die and a moving die. The fixed die comprises a fixed clamping plate, a stripper plate and a fixed die plate, the moving die comprises a moving clamping plate, square iron, a backing plate and a moving die plate which are fixed through screws, and a moving die guide post is mounted on the movable die plate and penetrates into a guide sleeve of the fixed die plate. An ejector base plate, an ejector retainer plate and an ejector rod are mounted on the inner side of the square iron, the ejector base plate and the ejector retainer plate are fixed through screws, four fixed die inserts are fixed onto the fixed die plate, four moving die inserts are correspondingly fixed onto the moving die plate, the moving die inserts and the fixed die inserts are correspondingly mounted, and four cavities for the gear of the paper turning device of the printer are formed after die closing, a large guide post is mounted on the fixed clamping plate and penetrates into the stripper plate, the fixed die plate, the square iron, the backing plate and the moving die plate, a pull rod is mounted on the stripper plate, and a sprue bush and a positioning ring are mounted on the fixed clamping plate. The die device can be used for producing four types of gears, meshing degree and stability of the gears are greatly increased, and the defects of charring, poor filling and the like of an original die are improved by the aid of blow holes and air vents.

Description

A kind of printer Paper leaf turner gear die device

Technical field

The utility model relates to mould applications, particularly a kind of printer Paper leaf turner gear die device.

Background technology

When making printer Paper leaf turner gear, exist the stability of product not high usually at present, the formed product difficulty is big, produced original mould be prone to burn, fills bad, mesh bad, the overproof grade of the gears engaged degree of production undesirable condition.

Therefore, in reality is produced, be sought after a kind ofly can guaranteeing the formed product precision simultaneously, and be difficult for burning, fill good a kind of printer Paper leaf turner gear die device.

The utility model content

The purpose of the utility model provides a kind of printer Paper leaf turner gear die device, the situation that the product of this die device production can avoid original mould to burn, and fill in order, the gears engaged degree improves greatly.

The technical scheme that adopts is:

A kind of printer Paper leaf turner gear die device comprises fixed half and moving half.

Its technical essential is:

Cover half comprises fixed clamping plate, stripper plate and solid plate.

Dynamic model comprises moving clamping plate, square iron, backing plate and the moving platen that screw is fixing.Installing dynamic model guide pillar on the moving platen.The dynamic model guide pillar is installed in the guide pin bushing of solid plate.

At fixing end needle plate and the face needle plate of the inboard installing of square iron screw, and the installing push rod.

Fixing four cover half mold inserts on solid plate.Fixing four dynamic model mold inserts of correspondence on moving platen.The corresponding installing with the cover half mold insert of dynamic model mold insert, matched moulds forms the die cavity of four printer Paper leaf turner gears later on.

The big guide pillar of installing on the fixed clamping plate, big guide pillar is installed in stripper plate, solid plate, square iron, backing plate and the moving platen.

Install sprue puller on the stripper plate, installing sprue bush and locating ring on the fixed clamping plate.Fixing limited block on the face needle plate.

Its advantage is:

This die device can be produced four kinds of gear products simultaneously, and every kind of gear meshing degree all met or exceeded the original designing requirement of product, and the stability of product improves greatly simultaneously.The design of air discharge duct between cover half mold insert and the dynamic model mold insert reduces the moulding difficulty greatly, has improved burning of original mould, fills bad, the overproof grade of engagement degree undesirable condition.

Description of drawings:

Fig. 1 is the structural representation of the utility model.

The specific embodiment:

Cover half comprises fixed clamping plate 1, stripper plate 2 and solid plate 3.

Dynamic model comprises moving clamping plate 9, square iron 6, backing plate 5 and the moving platen 4 that screw is fixing.Installing dynamic model guide pillar 13 on the moving platen 4.Dynamic model guide pillar 13 is installed in the guide pin bushing of solid plate 3.

At the fixing end needle plate 8 and face needle plate 7 of square iron 6 inboard installing screws, and installing push rod 17.

Fixing four cover half mold inserts 10 on solid plate 3.Fixing four dynamic model mold inserts 11 of correspondence on moving platen 4.Dynamic model mold insert 11 and the 10 corresponding installings of cover half mold insert, matched moulds forms the die cavity of four printer Paper leaf turner gears later on.

The big guide pillar 12 of installing on the fixed clamping plate 1, big guide pillar 12 is installed in stripper plate 2, solid plate 3, square iron 6, backing plate 5 and the moving platen 4.

Installing sprue puller 15 on the stripper plate 2, installing sprue bush and locating ring 14 on the fixed clamping plate 1.Fixing limited block 16 on face needle plate 7.

On cover half mold insert 10 and cover half mold insert 11, offer gas hole, connect outside blowing plant, play thermolysis.On cover half mold insert 10 and cover half mold insert 11, offer air discharge duct.

The die cavity that forms behind four cover half mold inserts 10 and cover half mold insert 11 matched moulds can be the precision gear of printer Paper leaf turner for the die cavity of four identical gears or the die cavity of four different gears.

Its operation principle is:

Fixed clamping plate 1 is installed on the make-up machine through tools such as pressing plates, it realize through locating ring 14 and make-up machine between the location.Stripper plate 2 and solid plate 3 can be in big guide pillar 12 enterprising line slips,

Partly realize positioning and guiding through dynamic model guide pillar 13 and cover half.Moving clamping plate 9 is installed in the movable side of make-up machine through tools such as pressing plates, and end needle plate 8 forms liftout attachments with face needle plate 7, realizes that under the thick stick effect of the top of make-up machine ejection device moves.

During die sinking, move back in the movable rear flank of make-up machine, will expect that earlier solid plate 3 was opened with moving platen in 4 minutes then throwing off, after the movable side of make-up machine stopped, ejecting mechanism began to eject action.After product ejected, the mould matched moulds began next molding cycle.
