Abstract
The invention discloses a self-recovery type anti-overflow spray nozzle. The self-recovery type anti-overflow spray nozzle is composed of main components including a spray nozzle cap, a spray nozzle body, a valve element and a spring. The self-recovery type anti-overflow spray nozzle is characterized in that in the plastic injection process, a hydraulic device pushes a threaded rod to move forward, and a high-pressure plastic injection glue melting area is formed in the spray nozzle cap which is sealed originally; high-pressure molten glue acts on the stress surface of the valve element, thrust is generated, the spring is compressed, and the valve element is made to move towards the spring; the blocking slope of the valve element retreats from a corresponding anti-overflow slope at the inner side of the spray nozzle cap at the moment, and a plastic injection channel is in an opened state; the molten glue is injected into a cavity in a die through the plastic injection channel in the spray nozzle body until plastic injection is completed; when the glue melting process starts, due to the fact that the hydraulic device drives the threaded rod to retreat, the pressure in the high-pressure glue melting area in the spray nozzle cap is relieved, under the effect of elastic force of the spring, the blocking slope of the valve element is pushed towards the corresponding anti-overflow slope again and attached to the anti-overflow slope, and the plastic injection channel is in a closed state; the plastic injection channel is blocked, so that the molten glue cannot overflow from the plastic injection channel, and it is guaranteed that the production process of products can be completed 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 self-resetting 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 self-resetting 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 self-resetting 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, at this moment the blocking inclined-plane of spool exits from the anti-overflow inclined-plane of the inner side correspondence of nozzle cap, for opening injection channel state, now melten gel is through the cavity of the injection channel injection mould of nozzle main body, until action of injection completes; When melten gel starts because hydraulic means drives screw retreats, pressure is removed in high-pressure glue melting zone in nozzle cap, the blocking post inclined-plane of spool is under the effect of the elastic force of spring, again push blocking inclined-plane to anti-overflow inclined-plane and fit, for closing injection channel state, 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 self-resetting 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, at this moment the blocking inclined-plane (3-1) of spool (3) exits from the anti-overflow inclined-plane (1-3) of the inner side correspondence of nozzle cap (1), as the duty of Fig. 2, now the injection channel (2-1) of melten gel through nozzle main body (2) and injection channel (1-2) 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 inclined-plane (3-1) of spool (3) is under the effect of the elastic force of spring (4), again will block inclined-plane (3-1) and push anti-overflow inclined-plane (1-3) to, and fit, 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.The cylinder face (3-3) of spool (3) adopts with nozzle main body (2) and is slidably matched in addition, and with positioning head (3-5) fixing spring (4), spring (4) is arranged on nozzle main body (2) inside and the blocking inclined-plane (3-1) of spool (3) adopts cone match with the anti-overflow inclined-plane (1-3) of nozzle cap (1), need not consider that cylinder face (3-3) and nozzle main body (2) in use produce wear and tear and produce to leak and expect, the service life of the anti-flash nozzle of raising self-resetting type.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 (3)
1. the anti-flash nozzle of self-resetting type comprises nozzle cap, nozzle main body, spool and spring is critical piece composition.
2. spring according to claim 1 and spool are arranged on nozzle body interior.
3. fit with anti-overflow inclined-plane and block injection channel in the blocking inclined-plane of spool according to claim 1 under the effect of the elastic force of spring, and melten gel cannot be overflowed from injection channel.
