Abstract
The utility model discloses a thermal -insulated runner cover, including runner cover body, runner cover body one end is inlayed and is had the heat insulation, is equipped with the runner that runs through runner cover body and heat insulation confession melting plastic and flow through on the runner cover body, in the operation of moulding plastics, the direct nozzle with the injection molding machine of heat insulation contacts, can block that the heat that comes from on the injection molding machine nozzle passes through the runner cover to mould inside transmission to can avoid the temperature nonuniform distribution's that the mould cavity temperature rose, mould cavity the is interior condition, adopt the product uniformity of the mould production of this kind of runner cover good, the rejection rate is low, can improve the production efficiency of product.
Description
[technical field]
This utility model relates to injection mold field, a kind of heat insulation sprue bush.
[background technology]
The sprue bush of current plastic mould is overall generally uses metal material to be fabricated by, this sprue bush has a disadvantage that injection when, it is easy to be delivered to inside mold cavity by the heat on injection molding machine nozzle, mold cavity temperature can be made to raise from the heat on injection molding machine nozzle, thus temperature distributing disproportionation in causing mold cavity is even, cause homogeneity of product bad, easily produce waste product, reduce production efficiency.
This utility model is aiming at sprue bush in prior art and easily the heat on injection molding machine nozzle is delivered to the defect within mold cavity and designs.
[utility model content]
The technical problems to be solved in the utility model is to provide a kind of heat insulation sprue bush, this heat insulation sprue bush includes sprue bush body, sprue bush body one end is inlaid with heat insulation, and sprue bush body is provided with and runs through the runner that sprue bush body and heat insulation flow through for melt plastic cement；Carrying out injection molding operation when, heat insulation directly contacts with the nozzle of injection machine, can stop from the heat on injection molding machine nozzle and be transmitted to mould inside by sprue bush, it is thus possible to avoid mold cavity temperature to raise, situation that temperature distributing disproportionation in mold cavity is even, use the good product consistency that the mould of this sprue bush produces, percent defective is low, can improve the production efficiency of product.
For solving above-mentioned technical problem, this utility model includes sprue bush body, and described sprue bush body one end is inlaid with heat insulation, and described sprue bush body is provided with and runs through the runner that sprue bush body and heat insulation flow through for melt plastic cement.
A kind of heat insulation sprue bush as above, described sprue bush body one end is provided with embedding piece groove, and described heat insulation is embedded on described sprue bush body by embedding piece groove.
A kind of heat insulation sprue bush as above, described heat insulation is provided with concave surface.
A kind of heat insulation sprue bush as above, described concave surface is sphere.
A kind of heat insulation sprue bush as above, described runner is taper and becomes larger along the direction that melt plastic cement flows.
A kind of heat insulation sprue bush as above, described sprue bush body is provided with recess with one end of heat insulation the same side, is provided with shoulder outside described recess.
Compared with prior art, this utility model is by arrange heat insulation with the position of injection molding machine nozzle on sprue bush body, can stop that the heat of injection molding machine nozzle is delivered to inside mold cavity by sprue bush, the temperature distributing disproportionation in the rising of mold cavity temperature, mold cavity can be avoided even, and then the quality of raising product, improve production efficiency.
[accompanying drawing explanation]
Below in conjunction with the accompanying drawings detailed description of the invention of the present utility model is described in detail, wherein:
Fig. 1 is top view of the present utility model；
Fig. 2 is the Fig. 1 sectional view along A-A direction.
[detailed description of the invention]
Below in conjunction with the accompanying drawings embodiment of the present utility model is elaborated.
As depicted in figs. 1 and 2, heat insulation sprue bush in the present embodiment includes sprue bush body 1, sprue bush body 1 one end is provided with embedding piece groove 4, heat insulation 2 is embedded on sprue bush body 1 by embedding piece groove 4, sprue bush body 1 is provided with and runs through the runner 3 that sprue bush body 1 and heat insulation 2 flow through for melt plastic cement, carrying out injection molding operation when, heat insulation 2 directly contacts with the nozzle of injection machine, can stop that the heat of injection molding machine nozzle is delivered to inside mold cavity by sprue bush, being avoided that mold cavity temperature raises, the temperature distributing disproportionation in mold cavity is even.
Heat insulation 2 is provided with the concave surface 5 that profile is sphere, and injection molding machine nozzle can be made to contact tightr with heat insulation 2 when injection molding operation, it is to avoid melt plastic cement is overflowed from the gap between injection molding machine nozzle and heat insulation 2.
Runner 3 is taper and becomes larger along the direction that melt plastic cement flows, and is so avoided that and makes melt plastic cement quick solidification in runner 3 because sprue bush temperature is lower than the temperature of injection molding machine nozzle, blocks runner 3.
Sprue bush body 1 is provided with recess 6 with one end of heat insulation the same side, and recess 6 is outside is provided with shoulder 7, is so easy to sprue bush and is assemblied on mould.
Sprue bush body 1 and heat insulation 2 are the most preferentially set to rotary structure in the present embodiment; certainly sprue bush body 1 or heat insulation 2 are set to other shapes such as square or oval and also can reach the effect that this utility model is identical, therefore also because of within protection domain of the present utility model.
