Abstract
The utility model discloses a dual color co-extrusion plastic shaping material mold, which comprises a rear mold body, a flow dividing transition board, a flow dividing bracket board, a core rod bracket board, a neck mold transition board, a spreader and a core rod which together form a spruce. The other neck mold transition board and a neck mold board are added. A half-side thread is respectively processed between the two boards in vertical direction. The two boards are connected by screws into a sealed co-extrusion material feed inlet in threading connection. A neck mold transition board under the feed inlet is provided with a flow channel, a convex block and a convex edge. The co-extrusion material is extruded from the co-extrusion flow channel to the spruce and meets the main material extruded from the neck mold board. The dual color co-extrusion can be realized by adopting the structure. After the co-extrusion processing, the shaped surface is short, which is good for molding, and the sticking force is firm.
Description
The utility model relates to a kind of plastic material mould, especially for bicolor co-extrusion plastic material mould.
At present, the mould of traditional PVC section bar can only be processed the PVC section bar of solid color, because its color dullness and appearance are easily aging, market demand reduces just year by year, and the beautiful and ageing-resistant composite material of a kind of outward appearance is released in market in urgent need.
The purpose of this utility model just is to provide a kind of can partly cover the skim different colours on the section bar of traditional solid color, thickness is the coextruded plastic product moulding mould of the lucite of 0.2-0.5mm.
The technical solution of the utility model is achieved in that by back die body, shunting rebound, shunting supporting plate, plug supporting plate, mouthful mould rebound, divides flow cone and plug to form sprue jointly, add a mouth mould rebound and mouth template, on vertical direction between two plates, respectively process a half of screw thread, this two plate is connected to form the co-extrusion material charging aperture that is threaded of a sealing with screw, this charging aperture lower port mould rebound is provided with runner, projection and chimb, the co-extrusion material presses to sprue through co-extruding flow channel, merges together through mouth template with major ingredient and extrudes.
As further improvement of the utility model, the mouth mould rebound that newly adds and the gap of plug are slightly less than the gap of mouth template and plug, are provided with a thermocouple hole on mouth template.
The utility model is simple in structure, and is reasonable in design, can realize the one-shot forming of bicolor co-extrusion plastic material, increase work efficiency, and double-colored section bar is beautiful ageing-resistant than the solid color section material appearance.
Below in conjunction with accompanying drawing the utility model is described in further detail:
Fig. 1 bicolor co-extrusion plastic material mode host visual pattern
Fig. 2 is that Figure 1A-A is to cutaway view
Fig. 3 is a mouth template front view shown in Figure 2
Fig. 4 is that Fig. 3 B-B is to cutaway view
Fig. 5 is a shown in Figure 2 mouthful of mould rebound front view
Fig. 6 is that Fig. 5 C-C is to cutaway view
Fig. 7 is that Fig. 5 D-D is to cutaway view
Shown in Fig. 1-7: form sprue 24 jointly by back die body 8, shunting rebound 7, shunting supporting plate 6, plug supporting plate 5, mouthful mould rebound 4, branch flow cone 13 and plug 10, co-extruding flow channel is located between mouth template 2 and mouthful mould rebound 3, co-extrusion aftershaping face is short, help moulding, and attached subsides power is firm.This co-extruding flow channel is relatively independent, and the flowing law that meets lucite, vertical direction is opened a complete runner between mouth template 2 and mouthful mould rebound 3, processing mode adopts cuts formula processing open, guarantees precision on the technology easily, and simplifies difficulty of processing, process the back and connect together the runner that forms sealing with screw 9, charging aperture adopts and is threaded, and good airproof performance does not leak material.Screw thread also adopts the processing of the formula of cutting open, the half of screw thread 16 of processing on mouth template 2, and the other half of screw thread 17 of processing on mouth mould rebound 3 is with becoming complete charging aperture connecting thread after screw 9 connections.According to the difference of section, charging aperture is arranged on different position, upper end.
The polyvinyl chloride of sprue (PVC) material enters sprue from back die body 8, through dividing the shunting of flow cone 13, it is mobile to tend towards stability on the shunting rebound, through reaching basicly stable behind shunting supporting plate 6 and the plug supporting plate 5, through mouthful mould rebound 4 compression back inlet port mould rebound 3 basic formings, plug 10 molding cavities.In addition, the co-extrusion material also enters from charging aperture, the co-extrusion material enters runner from 18 positions, in runner 20, flow,, reach the co-extrusion material is evenly spread to purpose in the runner through stopping of projection 19, process chimb 21 stopping again, further plasticizing and evenly dispersion materials flow behind the arrival zone 22, have promptly formed a pressure stability, materials flow is the good voltage stabilizing district of plasticizing evenly, through chimb 23, promptly mouthful mould part presses to sprue 24 uniformly and stably, merges together with sprue between mouth mould rebound 3 and mouth template 2, stable moulding through mouth template 2, common extrusion neck ring mold passes through cooling and shaping again, promptly becomes double-colored section bar.
In addition, the die cavity 24 of mouthful mould rebound 3 and plug 10 barrier between the co-extrusion part is slightly less than the die cavity 15 and the gap of plug 10 in the co-extrusion part of mouth template 2, and being beneficial to the co-extrusion material can steady flow after converging with sprue.Soket head cap screw 9 links together a mouth mould rebound 3 and a mouthful mould rebound 2, form the co-extruding flow channel of sealing, and then link together by soket head cap screw 1 each plate with whole die head, form an integral body, accurately locate between each plate by straight pin 12, supply with materials flow institute calorific requirement by heating collar 11, measure temperature by thermocouple hole 14.Between mouth mould rebound 3 and mouth template 2 because of there being co-extruding flow channel to exist, so exceed other each plates, to save material.
