Abstract
The invention discloses a chip removal type anti-overflowing nozzle. The chip removal type anti-overflowing nozzle comprises the main components including a nozzle cap, a nozzle body, a valve element and a spring. The chip removal type anti-overflowing nozzle is characterized in that a screw is pushed by a hydraulic device to advance during injection molding, an injection molding high-pressure molten plastic area is formed in the nozzle cap which is originally sealed, high-pressure molten plastic acts on the stress surface of the valve element, pushing force is generated and compresses the spring so that the valve element can move towards the spring till the limiting surface of the valve element is attached to the nozzle body, a blocking column of the valve element retreats from an injection molding channel of the nozzle cap completely at the moment, the molten plastic is injected into a cavity of a mold through the injection molding channel of the nozzle body at the moment till injection is completed, then the hydraulic device drives the screw to retreat, pressure in the high-pressure molten plastic area in the nozzle cap is released, the blocking column of the valve element is inserted into the injection molding channel again under the action of the elastic force of the spring, and the injection molding channel is blocked, so that molten plastic cannot overflow from the injection molding channel. In this way, a product can be produced smoothly.
Description
Technical field
The present invention relates to a kind of injection machine part, particularly relate to the anti-flash nozzle of a kind of chip removal type.
Background technology
At present, nozzle is as the vitals of on injection head in injection machine, usually when injection moulding, after barrel heating, after plastic grain is put into barrel from import, rotated side plastic grain being delivered to screw head by the screw rod in injection head, heater makes plastic grain constantly melt, then by hydraulic means lead-screw, will be expelled in the cavity of mould in the middle of the plastic warp nozzle of melting, complete the injection moulding action of molding machine.But some plastics is in melting process, overflows voluntarily from nozzle, on meeting sticking mould, the phenomenon that brings inconvenience is produced to mould, furthermore causes product rejection and burn failure.
Summary of the invention
The object of this invention is to provide the anti-flash nozzle of a kind of chip removal type.
In order to achieve the above object, the present invention adopts following technical pattern: it is critical piece composition that the anti-flash nozzle of chip removal type comprises nozzle cap, nozzle main body, spool and spring.Its feature: hydraulic means lead-screw advances when injection moulding, injection moulding high-pressure glue melting zone is formed in original nozzle cap closed, the melten gel of high pressure acts on the stress surface of spool, producing thrust Compress Spring makes spool move to spring direction, until the confined planes of spool and nozzle main body are fitted, at this moment the blocking post of spool all exits from the injection channel of nozzle cap, now melten gel is through the cavity of the injection channel injection mould of nozzle main body, until action of injection completes, hydraulic means drives screw retreats, pressure is removed in high-pressure glue melting zone in nozzle cap, the blocking post of spool is under the effect of the elastic force of spring, reinsert in injection channel, block injection channel, melten gel cannot be overflowed from injection channel.Thus ensure that product completes production process smoothly.
The present invention compared to existing technology tool has the following advantages: some are than being easier to the material occurring flash phenomena, occurs that being difficult to control flash phenomena can use the present invention aborning; Spool of the present invention, under the effect of the elastic force of spring, blocks injection channel, and melten gel cannot be overflowed from injection channel.The present invention adopts mechanical action, reliable and stable, makes completing smoothly of product produce stable further.Effectively damage mould phenomenon occur, further increase the stability of whole mould.

Detailed description of the invention: the anti-flash nozzle of chip removal type comprises nozzle cap (1), nozzle main body (2), spool (3) and spring (4) for critical piece composition.Its feature: hydraulic means lead-screw advances when injection moulding, injection moulding high-pressure glue melting zone is formed in original nozzle cap (1) closed, the melten gel of high pressure acts on the stress surface (3-2) of spool (3), producing thrust Compress Spring (4) makes spool (3) move to spring (4) direction, until the confined planes (3-4) of spool (3) and nozzle main body (2) are fitted, at this moment the blocking post (3-1) of spool (3) all exits from the injection channel of nozzle cap (1) (1-1), as the duty of Fig. 2, now melten gel is through the injection channel (2-1) of nozzle main body (2), injection channel (1-3) and injection channel (1-1) inject the cavity of mould, until action of injection completes, hydraulic means drives screw retreats, pressure is removed in high-pressure glue melting zone in nozzle cap (1), the blocking post (3-1) of spool (3) is under the effect of the elastic force of spring (4), reinsert in injection channel (1-1), block injection channel (1-1), melten gel cannot be overflowed from injection channel (1-1), as the duty of Fig. 2.Thus ensure that product completes production process smoothly.Spring (4) installing zone (2-2) set up in the middle part of nozzle main body (2) in addition, exhaust in injection moulding process can be ensured and get rid of some to produce material bits, be convenient to the maintenance of later stage nozzle, the cylinder face (3-3) of spool (3) and nozzle main body (2) adopt sealing to be slidably matched, and with positioning head (3-5) fixing spring (4).The present invention is not limited to above-mentioned preferred forms, and anyone should learn the structure change made under enlightenment of the present invention, and every have identical or close technical scheme with the present invention, all falls within protection scope of the present invention.
Claims (4)
1. the anti-flash nozzle of chip removal type comprises nozzle cap, nozzle main body, spool and spring is critical piece composition.
2. spring fitting according to claim 1 installing zone outside injection channel.
3. the cylinder face of spool described in claim 1 and nozzle main body adopt sealing to be slidably matched, can free action under the elastic force effect of spring.
4. the blocking post of spool according to claim 1 is under the effect of the elastic force of spring, blocks injection channel, and melten gel cannot be overflowed from injection channel.
