Description
Technical field
The present invention relates to a kind of device of plastic processing, more particularly to a kind of injection machine with external cooling device.
Background technology
Current plastic products are widely used, and the processing of plastic products typically uses injection molding, but due to plastics production
Product largely have certain plasticity, to reduce or avoiding product to be deformed after the completion of being molded, it usually needs after injection
Product is cooled down.It presently, there are and product is cooled down using cooling shaping fixture, although, but deposit on fixed effect preferably
The problem of man-hour, long efficiency was low.And be to improve cooling effectiveness to one the product release after being molded to be exclusively used in into product cold
But in bosh, but it can typically be swum in because the density of plastic products is relatively low on the water surface so that the part of plastic products
Cannot effectively cool down, if plastic products are immersed into water one by one by manual operation, can be lifted cost of labor and this
The mode of kind is relatively low in cooling effectiveness.
The content of the invention
It is an object of the invention to provide a kind of injection machine with external cooling device, it may be such that the product completed after injection is obtained
To sufficient cooling, and the artificial operation of substitution improves cooling effectiveness.

With reference to Fig. 6 and Fig. 7, vertical feed part is in the present embodiment a binder oil cylinder 252, in binder oil cylinder 252
A holding pad 253 is connected with second piston bar 2521, holding pad 253 is horizontally disposed and is metal material；In holding pad 253
Side on be provided with scraping wings 254, scraping wings 254 and holding pad 253 are orthogonal, and if being offered on scraping wings 254
Did the mouth of a river 2541.
Specific to combine Fig. 3, holding pad 253 is similarly in horizontally disposed, and the length of holding pad 253 in bosh 23
With the similar width of bosh 23, it is to avoid product is from gap when being squeezed from holding pad 253 and the inwall of bosh 23
In float up.Scraping wings 254 is positioned close to the side of water inlet 233, and with certain height.
Fig. 8, which is shown in the connection signal of the oil circuit of binder oil cylinder 252, injection machine 10, also includes ejection cylinder 11, the top
The fuel-displaced power source that blanking is molded as injecting products, including the first rod chamber 111 and the first rodless cavity 113, the first rod chamber
111 are separated with the first rodless cavity 113 by First piston bar 112.Binder oil cylinder 252 equally includes the second rod chamber 2522
With the second rodless cavity 2523, the second rod chamber 2522 is separated with the second rodless cavity 2523 by second piston bar 2521.
First rodless cavity 113 is connected with an oil-feed house steward 12, and the first rod chamber 111 is connected with an oil return house steward 13,
When hydraulic oil enters the first rodless cavity 113 by oil-feed house steward 12, First piston bar 112 can be promoted to stretch out now injection production
Product start to be stripped blanking, and the hydraulic oil being in the first rod chamber 111 is back in fuel tank from oil return house steward 13.Conversely
When hydraulic oil enters the first rod chamber 111 by oil return house steward 13, First piston bar 112 retract now enter it is next
In secondary injection cycle, and the hydraulic oil being in the first rodless cavity 113 is back in fuel tank from oil-feed house steward 12.
One is connected with second rodless cavity 2523 of binder oil cylinder 252 and enters oil inlet pipe 2524, and this enters oil inlet pipe 2524
The other end is connected on the branch road of oil return house steward 13；An oil returning branch pipe is connected with second rod chamber 2522 of binder oil cylinder 252
2525, the other end of the oil returning branch pipe 2525 is connected on the branch road of oil-feed house steward 12.
When this injection machine 10 works, moulding 30 is molded in injection mold, when completing injection, injection mold die sinking,
Ejection cylinder 11 is acted, and hydraulic oil is entered in the first rodless cavity 113 from oil-feed house steward 12 promotes First piston bar 112 to stretch out,
Moulding 30 is ejected from die cavity or core, at the same time, section hydraulic oil enters binder by oil returning branch pipe 2525
In second rod chamber 2522 of oil cylinder 252 so that the second piston bar 2521 of binder oil cylinder 252 is retracted, and drives holding pad 253
Toward the lateral movement away from bosh 23, moulding 30 is dropped in blanking channel 21 after being ejected, and smoothly dropped into
In bosh 23.
When injection mould closing, the First piston bar 112 of ejection cylinder 11 is resetted, and hydraulic oil passes through oil return house steward
13 are entered in the first rod chamber 111, and section hydraulic oil is entered in the second rodless cavity 2523 by entering oil inlet pipe 2524,
Promote the second piston bar 2521 of binder oil cylinder 252 to stretch out, and drive holding pad 253 toward the side displacement of bosh 23, binder
Plate 253 is acted on the moulding 30 dropped in bosh 23, it is totally submerged in cooling medium, whole flow process is pressed
Circulated according to above-mentioned action.
The discharging to moulding 30 is carried out after certain shot is completed to reclaim, particularly when in this discharging recovery state
When, second piston bar 2521 is in stretching state i.e. moulding 30 in the presence of holding pad 253 also in being totally submerged
In cooling medium.Now horizontal feed part 251 works, and drives binder oil cylinder 252 toward the side displacement of discharging opening 234, due to
The density of moulding 30 is relatively low to be close under the lower section of holding pad 253, and the barrier effect of scraping wings 254 being swept progressively
To the one end of discharging opening 234.Plane at other holding pad 253 is located at the lower section of the hinged place of closed plate 231, when binder oil cylinder
252 continue to be close to when 234 side of discharging opening by driving, pressure plare can progressively push up Kaifeng closing plate 231 and cause closed plate 231 around
Pin joint is rotated, and now discharging opening 234 is opened while horizontal feed part 251 is stopped as shown in figure 9, cooling down Jie
Matter is poured in splicing tank 24 under gravity, while moulding 30 is same from discharging opening under the drive of cooling medium
234 out enter collection in splicing case 29.
After the cooling medium in bosh 23 almost all comes down in torrents light, start water circulating pump 27, will be from bosh
The cooling medium received in 23 is returned in bosh 23, but because now discharging opening 234 is also in open state,
Return the cooling medium come to spray into from the side of water inlet 233, the inside of bosh 23 is washed away and is trapped in exhausted small part
Moulding 30 washes away away in bosh 23, and until all mouldings 30, out Posterior circle water pump 27 stops out of bosh 23
If machine can skip this step in bosh 23 certainly in a removal process without delay moulding 30.When completion is washed away
Horizontal feed part 251 works afterwards, and driving binder oil cylinder 252 resets, being separated with closed plate 231 progressively of holding pad 253, closes
Plate 231 is resetted in the presence of spring hinge and most discharging opening 234 is closed at last.Now water circulating pump 27 is again turned on and mended
Feed pump 28 is equally opened, and cooling medium is injected into bosh 23 is used for the cooling down operation of next time, and to bosh
In 23 during injection cooling medium, splicing case 29 can artificially be taken out from splicing tank 24, and all mouldings 30 from splicing
Pour out, splicing case 29 is put into splicing tank 24 again in case 29 after reclaiming well.
This specific embodiment is only explanation of the invention, and it is not limitation of the present invention, people in the art
Member can make the modification without creative contribution to the present embodiment as needed after this specification is read, but as long as at this
All protected in the right of invention by Patent Law.
