Abstract
The utility model discloses a composite co-extrusion tubular plastic lampshade extrusion die which comprises an orifice template, a conflux plate, a transition plate and a die body, and is characterized by further comprising a location pin, a core bar, a small screw and a plurality of long screws, wherein a main runner which goes through from left to right is formed among the orifice template, the conflux plate, the transition plate and the die body; an outer screw thread is formed on an outer circular surface on the right part of the die body; a main material inlet is formed in the right end of a die body inner hole; a bypass material inlet and a bypass runner are formed on the conflux plate; a round hole and an end face runner are formed on the orifice template; the end face runner comprises two symmetrically arranged branched runners; two symmetrical grooves are formed in the core bar; one end of the end face runner is communicated with a round hole of the orifice template and the other end of the end face runner is communicated with the bypass runner. According to the extrusion die disclosed by the utility model, one half part of a machined tubular plastic lampshade is excellent in light transmittance while the other half part is light tight, and the lampshade is beautiful in appearance and low in cost.
Description
Technical field
The utility model relates to mould, particularly a kind of composite co-extruding circular tube shaped plastic lamp shade extrusion die.
Background technology
Existing circular tube shaped lampshade adopts glass or single transparent plastics to make mostly, glass lamp shade is frangible, although the lampshade that single transparent plastics are made is easy to processing, but comparatively dull, for the occasion with special-effect, as one of: lampshade semi-transparent good, second half of lampshade is light tight, if adopt the mould of plastics of existing single charging aperture cannot process.
Utility model content
The purpose of this utility model be just to provide a kind of circular tube shaped plastic lamp shade one processing semi-transparent good, second half is light tight, good looking appearance, composite co-extruding circular tube shaped plastic lamp shade extrusion die that cost is low.
For achieving the above object, the utility model comprises mouth template, cylinder manifold, rebound and die body, also comprise alignment pin, plug, Screw and several long spiro nails, at described mouth template, cylinder manifold, between rebound and die body, be provided with the sprue connecting from left to right, the outer round surface of described die body right part is provided with external screw thread, the right-hand member of described die body endoporus is provided with main charging aperture, described cylinder manifold is provided with other charging aperture and by-pass flow road, described mouth template is provided with circular hole and end face runner, described end face runner comprises two symmetrically arranged branch flow passages, described plug is provided with two symmetrical grooves, one end of described end face runner is communicated with the circular hole of mouth template, the other end of described end face runner is communicated with by-pass flow road, the left part of described alignment pin is loaded in the hole of plug, the right part of described alignment pin is loaded in the hole of cylinder manifold, described plug is threaded onto in the circular hole of mouth template and adopts Screw to be loaded on cylinder manifold, described long spiro nail is successively by mouth template, cylinder manifold, rebound is connected with die body.
The utility model is owing to being provided with circular hole on mouth template, plug is threaded onto in the circular hole of mouth template, between circular hole on plug and mouth template, form one and extrude die cavity, be provided with main charging aperture at the right-hand member of die body endoporus, and at mouth template, cylinder manifold, between rebound and die body, be provided with the sprue connecting from left to right, transparent plastic fluid just can enter from main charging aperture, process the upper transparent in circular tube shaped plastic lamp shade through sprue inlet port template, again owing to being provided with other charging aperture and by-pass flow road on cylinder manifold, on mouth template, be provided with end face runner, one end of end face runner is communicated with the circular hole of mouth template, the other end of end face runner is communicated with by-pass flow road, opaque plastic liquid just can enter from other charging aperture, through by-pass flow road, end face runner inlet port template composite co-extruding processes opaque lower one side of something in circular tube shaped plastic lamp shade, in addition, the end face runner being made up of two symmetrically arranged branch flow passages, can improve mobility and the uniformity of plastic liquid, extrudes quality thereby improve.The circular tube shaped plastic lamp shade one that the utility model processes is semi-transparent good, and second half is light tight, good looking appearance, and cost is low.
