Abstract
The utility model discloses a kind of sprue bushings with refrigerating function, include base part in a circular table shape, cylindrical runner hub sections, the runner hub sections grafting is in the lower section of the base part；The centre of the runner hub sections is equipped with the runner for extending base part, and the runner hub sections are equipped with cooling water channel around its described runner, and the lower section of the base part is equipped with the water inlet and water outlet that are connected with the cooling water channel.The utility model adds cooling water channel on the basis of original sprue bushing, reduces mold temperature, ensure that mold temperature balances, the deformation for reducing mold, effectively shortens mold cooling time, deform material head will not, and be easy to break, wire drawing is short, improves mold production efficiency.
Description
Technical field
The utility model relates to a kind of molds to use accessory, in particular to a kind of sprue bushing with refrigerating function.
Background technique
In the production process of plastic products, the plastic material of melting is injected into mould inside, mould from the nozzle of injection molding machine
Cry the metal fittings of " sprue bushing " as intermediate connection by one kind between tool and injection molding machine.During generation, the temperature of mold
It can slowly increase.Sprue bushing common at present not can guarantee the equalized temperature of mould inside, is easy to deform mold, influences mould
The service life of tool, and reduce production efficiency.Sprue bushing common at present can not effectively reduce the cooling time of material head, lead to material head
It is easy to appear deformations.In addition, being also easy to that material head is caused to be not easy to break, there is the case where long wire drawing, influence the quality of production.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of sprue bushing with refrigerating function.
To achieve the above object, the utility model adopts the following technical solutions: a kind of sprue bushing with refrigerating function, packet
Base part in a circular table shape, cylindrical runner hub sections are included, the runner hub sections grafting is in the pedestal
Partial lower section；The centre of the runner hub sections is equipped with the runner for extending base part, and the runner hub sections are enclosed
Be equipped with cooling water channel around runner described in its, the lower section of the base part be equipped with the water inlet being connected with the cooling water channel and
Water outlet.
It is further described, the cooling water channel includes the L-shaped return portion for entering water section, being C-shaped, water outlet
Part, it is described enter water section upper end be connected to the water inlet, lower end is connected to return portion；Centre is that several segments return portion is first
Tail connects, and forms semi-surrounding distribution along the runner；Final stage return portion is connected to the water part, the water part
It is connected to the water outlet.
Be further described, the top of the base part is equipped with half bowl-shape nozzle connecting pin, the nozzle connecting pin with
The runner is connected.
It is further described, the water inlet and water outlet are symmetric in the x-direction.
It is further described, is set above the base part there are two the counter sink for being used for connecting mold, the counter sink is along y
Direction is symmetric.
The utility model has the beneficial effects that: the utility model adds cooling water channel on the basis of original sprue bushing, drop
Low mold temperature ensure that mold temperature balances, reduce the deformation of mold.Additionally it is possible to which it is cold effectively to shorten mold
But the time deform material head will not, and material head is easy to break, and wire drawing is short, improve mold production efficiency.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the cross-sectional view of the utility model.
Drawing reference numeral: 1, base part；11, counter sink；12, nozzle connecting pin；13, water inlet；14, water outlet；2, it flows

Specific embodiment
It is practical new to this below in conjunction with attached drawing to keep the purpose of this utility model, technical solution and advantage clearer
Type is described in further detail.
As shown, a kind of sprue bushing with refrigerating function, includes base part 1 in a circular table shape, cylindrical
Runner hub sections 2, runner hub sections 2 are grafted in the lower section of base part 1；The centre of runner hub sections 2, which is equipped with, to be extended
The runner 24 of base part 1 out, runner hub sections 2 are equipped with cooling water channel around its runner 24, and the lower section of base part 1 is equipped with
The water inlet 13 and water outlet 14 being connected with cooling water channel.
Cooling water channel include it is L-shaped enter water section 21, the return portion being C-shaped 22, water part 23, enter water
The upper end of part 21 is connected to water inlet 13, and lower end is connected to return portion 22；Centre is that several segments return portion 22 is end to end, edge
Runner 24 forms semi-surrounding distribution；Final stage return portion 22 is connected to water part 23, and water part 23 is connected to water outlet 14.
Coolant liquid is flowed into from water inlet 13, is cooled down through cooling water channel to runner, then is flowed out from water outlet 14.
The top of base part 1 is equipped with half bowl-shape nozzle connecting pin 12, and nozzle connecting pin 12 is connected with runner 24.Stream
Road 24 is cone, and range of taper is 2 ° to 6 °.Water inlet 13 and water outlet 14 are symmetric in the x-direction.Base part 1
Top is set there are two the counter sink 11 for being used for connecting mold, and counter sink 11 is symmetric in the y-direction.
The above is not limit the technical scope of the present invention, all real according to the utility model technology
Matter still falls within the technical solution of the utility model to any modification, equivalent variations and modification made by above embodiment
In range.
