Abstract
The invention discloses a heat insulation sprue bushing. The heat insulation sprue bushing comprises a sprue bushing body. A heat insulation block is embedded in one end of the sprue bushing body. A flow channel penetrating the sprue bushing body and the heat insulation block and used for molten plastic to flow through is arranged on the sprue bushing body. When injection molding work is conducted, the heat insulation block is in direct contact with a nozzle of an injection molding machine, heat from the nozzle of the injection molding machine can be prevented from being transmitted into a die through the sprue bushing, and therefore the phenomena that the temperature of a cavity of the die is increased, and temperature distribution in the cavity of the die is not uniform are avoided. By means of the die with the sprue bushing, the consistency of produced products is good, the rejection rate is low, and the production efficiency of the products can be improved.
Description
[technical field]
The present invention relates to injection mold field, especially a kind of heat insulation sprue bush.
[background technology]
The sprue bush entirety of current plastic mould adopts metal material manufacture to form conventionally, thisSprue bush has a shortcoming: in injection moulding, be easy to the heat on injection molding machine nozzle to passBe delivered to mold cavity inside, can make mold cavity temperature liter from the heat on injection molding machine nozzleHeight, thus cause that the temperature distributing disproportionation in mold cavity is even, cause homogeneity of product bad,Easily produce waste product, reduce production efficiency.
The present invention is exactly easily by the heat on injection molding machine nozzle for sprue bush in prior artBe delivered to the defect of mold cavity inside and design.
[summary of the invention]
The technical problem to be solved in the present invention is to provide a kind of heat insulation sprue bush, this heat insulation cast gateCover includes sprue bush body, and sprue bush body one end is inlaid with heat insulation, on sprue bush bodyBe provided with and run through the runner that sprue bush body and heat insulation flow through for melt plastic cement; Carrying out injection moulding workWhen industry, heat insulation directly contacts with the nozzle of injection machine, can stop from injection molding machine nozzleOn heat by sprue bush to mould inside transmission, thereby can avoid mold cavity temperature literThe even situation of temperature distributing disproportionation in height, mold cavity, adopts the mould of this sprue bush rawThe good product consistency of producing, percent defective is low, can improve the production efficiency of product.
For solving the problems of the technologies described above, the present invention includes sprue bush body, described sprue bushBody one end is inlaid with heat insulation, described sprue bush body be provided with run through sprue bush body andThe runner that heat insulation flows through for melt plastic cement.
The heat insulation sprue bush of one as above, described sprue bush body one end is provided with mold insertGroove, described heat insulation is embedded on described sprue bush body by embedding piece groove.
The heat insulation sprue bush of one as above, described heat insulation is provided with concave surface.
The heat insulation sprue bush of one as above, described concave surface is sphere.
The heat insulation sprue bush of one as above, described runner is taper and flows along melt plastic cementIt is large that moving direction becomes gradually.
The heat insulation sprue bush of one as above, described sprue bush body and heat insulation the same sideOne end be provided with recess, described recess outside is provided with shoulder.
Compared with prior art, the present invention is by sprue bush body will be with injection molding machine nozzlePosition arranges heat insulation, can stop that the heat of injection molding machine nozzle is delivered to mould type by sprue bushInside, chamber, can avoid the temperature distributing disproportionation in the rising of mold cavity temperature, mold cavity even,And then the quality of raising product, enhance productivity.
[brief description of the drawings]
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail, wherein:
Fig. 1 is top view of the present invention;
Fig. 2 is the cutaway view of Fig. 1 along A-A direction.
[detailed description of the invention]
Below in conjunction with accompanying drawing, embodiments of the present invention are elaborated.
As depicted in figs. 1 and 2, the heat insulation sprue bush in the present embodiment includes sprue bush body1, sprue bush body 1 one end is provided with embedding piece groove 4, and heat insulation 2 is embedded in by embedding piece groove 4On sprue bush body 1, sprue bush body 1 is provided with and runs through sprue bush body 1 and heat insulation 2The runner 3 flowing through for melt plastic cement, in carrying out injection molding operation, heat insulation 2 directly withThe nozzle contact of injection machine, can stop that the heat of injection molding machine nozzle is delivered to mould by sprue bushTool die cavity inside, can avoid mold cavity temperature to raise, the temperature distributing disproportionation in mold cavityEven.
Heat insulation 2 is provided with the concave surface 5 that profile is sphere, in the time of injection molding operation, can make injection machineNozzle contacts closelyr with heat insulation 2, avoids melt plastic cement from injection molding machine nozzle and heat insulationOverflow in gap between piece 2.
Runner 3 is for taper and become gradually greatly along the mobile direction of melt plastic cement, can avoid like this because ofFor sprue bush temperature is set in rapidly runner 3 than the low melt plastic cement that makes of the temperature of injection molding machine nozzleIn, block runner 3.
Sprue bush body 1 is provided with recess 6 with one end of heat insulation the same side, and establish recess 6 outsidesThere is shoulder 7, be convenient to like this sprue bush and be assemblied on mould.
Sprue bush body 1 and heat insulation 2 are all preferentially set to revolving body knot in the present embodimentStructure, is set to other shapes such as square or oval by sprue bush body 1 or heat insulation 2 certainlyShape also can reach the effect that the present invention is identical, therefore also because of within protection scope of the present invention.
