Description
Technical field
The invention relates to technical field of mold, relates in particular to a kind of hot runner mould.
Background technology
For the injection mold of hot runner structure form, there is molding cycle length, poor product quality and waste raw-material defect in cold runner structure; In order to overcome the existing defect of traditional cold runner structure, hot runner structure is little by little applied, the injection mold generally adopting at Injection Industry is at present hot runner mould, its generally comprise hot runner manifold, with the fixing hot mouth of hot runner manifold, raw material enters hot runner manifold by injection machine and enters Re Zui again, enters in the mold cavity of product by hot mouth.Hot runner mould has and economizes in raw materials with respect to traditional cold runner die, improves product quality, can enhance productivity, and improves product quality, simplifies the plurality of advantages such as product subsequent handling.
Although hot runner mould has plurality of advantages, also there is certain deficiency in it.In actual production, during mould die sinking, template and hot mouth usually have friction, in long-term use procedure, can damage hot mouth, affect the service life of hot mouth; And hot mouth heat loss when die sinking is very fast, easily affects its speed of production and product quality; And, because hot mouth is not well fixed in mould, be difficult to guarantee the stability of hot mouth.
Summary of the invention
The object of the invention is to avoid above-mentioned weak point of the prior art and a kind of hot runner mould is provided, and can prevent hot mouth wearing and tearing, guarantees that hot mouth is durable, guarantees hot mouth injection moulding quality, improves heat able to keep a secret qualitative.
The object of the invention is achieved through the following technical solutions:
A kind of hot runner mould is provided, comprise hot mouth, flow distribution plate and hot runner manifold, hot mouth comprises the hot gonys seat connecting successively, hot mouth body and hot mouth, described hot runner manifold is provided with the hot mouth installing hole of perforation, described hot mouth is installed on described hot mouth installing hole, one end face of described hot gonys seat fits tightly in flow distribution plate, described hot mouth also comprises and is sheathed on described hot mouth, the hot mouth sheath of hot mouth body and hot mouth base exterior, hot mouth sheath comprises sheath mount, sheath body and sheath mouth, the outer wall of the inwall of sheath mount and hot gonys seat fits tightly, between the outer wall of the inwall of sheath body and hot mouth body, leave gap, the inwall of sheath mouth and the outer wall of hot mouth fit tightly.
Wherein, described hot mouth sheath is fixedly installed in described hot runner manifold by described sheath mount.
Wherein, described hot mouth sheath is fixedly installed in described flow distribution plate by described sheath mount.
Wherein, described hot mouth sheath and described hot mouth are fixed as one.
Wherein, described hot runner manifold is provided with the groove matching with described sheath mount, and described sheath mount is flush-mounted in described groove.
Wherein, the inwall of described sheath is provided with card convex, and the outer wall of described hot mouth is provided with screens, and described card convex and clamping matching are pressed in described flow distribution plate by described hot mouth.
Wherein, the gap between sheath body and hot mouth body is 0.1mm～5mm.
Wherein, described hot mouth sheath is the hot mouth sheath of steel.
The beneficial effect of the invention:
A kind of hot runner mould of the invention, by the sheathed hot mouth sheath of the outer surface at hot mouth, for the protection of hot mouth, while avoiding mould die sinking, template and hot mouth friction and damage hot mouth, guaranteed the service life of hot mouth.Between sheath body and hot mouth body, leave gap, prevent that the logical heat transfer of heat of hot mouth scatters and disappears fast, preserve the heat of hot mouth, thereby guarantee the quality of fluency and the injecting products of production process.The inwall of the inwall of sheath mount and sheath mouth fits tightly with the outer wall of hot gonys seat and the outer wall of hot mouth respectively, guarantees the stability of hot mouth.
