Abstract
A kind of nozzle arrangements of rubber injection moulding machine, it is characterized in that: nozzle body is made up of mouth, neck and connecting portion order, location shoulder is provided with between mouth and neck, connecting portion is provided with external screw thread, nozzle body neck outer wall is provided with the coolant jacket that can hold liquid communication, described coolant jacket adopts Welding Structure to combine by inner sleeve and overcoat, described coolant jacket be provided with side by side influent stream mouth for being communicated with cooling line and go out head piece, described influent stream mouth and going out to be provided with between head piece for control flow check to dividing plate.The utility model structure is simple, convenient, and its cooling performance meets injection characteristic completely, metering sizing material can be injected to die cavity completely, thus reduce goods percent defective, reach the manufacture requirements of high accuracy goods.
Description
Technical field
The utility model relates to a kind of injection moulding machinery technical field, particularly relates to a kind of improvement of nozzle arrangements of rubber injection moulding machine.
Background technology
The injection characteristic of rubber injection moulding machine determines that its injection pressure is higher, and the shear heat of generation is higher more to last injection.Therefore, need nozzle now to cool fast, to control sizing material temperature, prevent sizing material scorching, like this metering sizing material is injected to die cavity completely, reduce goods percent defective, reach the manufacture requirements of high accuracy goods.And the very difficult control of the rubber injection moulding machine nozzle temperature of prior art, because nozzle bore is little, shear heating seriously during injection, the temperature difference before and after sizing material when causing injecting, and internal-external temperature difference is comparatively greatly, percent defective is very high, can not meet the requirement of high accuracy goods.
Summary of the invention
Main purpose of the present utility model is: overcome rubber injection moulding machine when injecting, the problem that the shearing heating temp of nozzle affects product quality, thus make improvements nozzle for injection molding machine, and develop a kind of nozzle being provided with coolant jacket.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of nozzle arrangements of rubber injection moulding machine, the nozzle body that there is nozzle body and be communicated with nozzle body, it is characterized in that: described nozzle body is made up of mouth, neck and connecting portion order, location shoulder is provided with between mouth and neck, connecting portion is provided with external screw thread, and the internal thread that described external screw thread and nozzle body are arranged is adaptive; Be provided with the coolant jacket that can hold liquid communication along nozzle body outer wall, described coolant jacket be provided with side by side influent stream mouth for being communicated with cooling line and go out head piece, described influent stream mouth and going out to be provided with between head piece for control flow check to dividing plate.
The technical solution of the utility model can also be perfect further:
As preferably, described coolant jacket is arranged at the neck of nozzle body; Coolant jacket lower end is takeed on location and is abutted, and upper end is close to connecting portion male ends.
As preferably, described coolant jacket adopts Welding Structure to combine by inner sleeve and overcoat, and the neck outer wall of its inner sleeve and nozzle body closely cooperates.
As preferably, with influent stream mouth with go out cooling line that head piece is connected along nozzle body axially-aligned, but not contact with nozzle body with hot plate, described influent stream mouth and go out the both sides that head piece is divided in dividing plate.
The utility model beneficial effect is:
1) apparatus structure is simple, convenient.Because nozzle and nozzle body will stretch in the locating hole of hot plate, must be simple and convenient.The utility model coordinates with external cooling system, and its cooling performance is reliable; When nozzle body needs can unscrew screw thread when exchanging, nozzle is separated with nozzle body, exchanges a whole set of nozzle (comprise nozzle body and be connected to the coolant jacket above nozzle body); Also coolant jacket can be unloaded down from nozzle body, only exchange nozzle body, very convenient.
2) determine that its injection pressure is higher, and the shear heat of generation is higher more to last injection by injection characteristic, need nozzle now to cool fast, to control sizing material temperature, prevent sizing material scorching.The utility model meets above-mentioned injection characteristic completely, metering sizing material can be injected to die cavity completely, thus reduce goods percent defective, reach the manufacture requirements of high accuracy goods.

Detailed description of the invention
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1:
The nozzle arrangements of rubber injection moulding machine as shown in the figure, nozzle body 1 is threaded with nozzle body b, nozzle body is divided into mouth 13, neck 12 and connecting portion 11, the cylindrical cover of neck 12 has cooling inner sleeve 2(lower end to abut with location shoulder 14) described cooling inner sleeve 2 and neck outer wall close contact, the outer surface cover of described cooling inner sleeve 2 has cooling jacket 3, have the cavity being suitable for liquid flow between cooling inner sleeve and cooling jacket, and inner sleeve is welded with the two ends of overcoat are all-round; Cooling jacket 3 is set side by side with influent stream mouth 5 and goes out head piece 6, cavity internal fixtion between Liang Kou has dividing plate 4, to guide flow direction, described influent stream mouth 5 with go out head piece 6 and be connected with the cooling line 7 along nozzle body b axially-aligned, but not contact with nozzle body with hot plate.
During use, when injection pressure strengthens, sizing material is to hemostasis, sizing material produces increasing shear heat when nozzle, and now cooling line 7 is intake to influent stream mouth 5, and enters cooling inner sleeve 2 and cooling jacket 3 inner ring, because there is dividing plate 4 centre, by going out head piece 6 water outlet after cooling water circulation, take away the heat of nozzle, reduce nozzle temperature, to control sizing material temperature, prevent sizing material scorching, like this metering sizing material is injected to die cavity completely, reduce goods percent defective, reach the manufacture requirements of high accuracy goods.
Embodiment 2
The difference part of the present embodiment and the present embodiment 1 is, cooling jacket is directly socketed and is fixed on outside nozzle body 1 neck 12 does not establish inner sleeve, and its benefit is that cooling effectiveness is high, and structure is simple.But when nozzle changed by needs, cooling segment also needs to change thereupon.Other are identical with embodiment 1.
