Abstract
The utility model discloses a rubber mold cold runner system, which comprises a lower mold plate, an upper runner plate, a lower runner plate and a heat insulation plate, wherein the lower mold plate is fixedly installed on a base, the lower mold plate is fixedly provided with an upper mold plate, a mold cavity is arranged between the upper mold plate and the lower mold plate, the upper mold plate is provided with an injection nozzle, the upper surface of the upper mold plate is fixedly provided with the heat insulation plate, the lower runner plate and the upper runner plate are fixedly installed on the heat insulation plate, a runner is arranged between the upper runner plate and the lower runner plate, the upper runner plate is provided with a gate sleeve, the gate sleeve is communicated with the runner, and the runner is communicated with the lower injection nozzle. The rubber mold cold runner system is higher in production efficiency, lower in cost and higher in stability of the product quality.
Description
Technical field
The present invention relates to a kind of rubber mold cold runner system.
Background technology
The thermal treatment zone of General Purpose Rubber mold runner and mould is indiscrete, and mould heats together, and the sizing material in the runner vulcanizes simultaneously, a large amount of sizing materials has just been wasted in every like this mould secondary fluid course, also will lose time the sizing material in the runner is taken out, this mould production cost is high, and efficient is low.And cold runner die to be runner and mold heated district with mould separate with heat-barrier material, rubber vulcanizes in the thermal treatment zone like this, and the low not sulfuration of the sizing material temperature in the runner can continue to use.When mold cold flow passage system traditional design, runner is the deep hole that distributes in length and breadth in a template, by plug, two logical, threeway the sizing material guiding is entered injection nozzle, and fineness is difficult to reach the requirement of runner fineness during such deep hole machining; Runner is owing to be the turnover of 90 degree, and the pressure loss is larger; Remaining sizing material cleaning difficulty is very large in the runner.Only have dirty guidance tape cooling system during traditional design, do not have the injection nozzle cooling system, because injection nozzle directly contacts with the high temperature patrix, can cause like this sizing material in the injection nozzle very easily to vulcanize, thereby cause the obstruction of injection nozzle; The flow that enters each die cavity during Design of Dies should equate that the density of each product of guarantee is identical like this; To equate by the flow channel length that guarantees each die cavity during traditional design, thereby reaching the flow that enters each die cavity equates, and in the actual production because a variety of causes, even isometric runner, enter that the flow of each die cavity neither equate, so just need to regulate the flow that enters each die cavity, and not have in the traditional design.
Summary of the invention
It is higher to the invention provides a kind of production efficiency, and cost is lower, the rubber mold cold runner system that the stability of product quality is higher.
Technical solution problem of the present invention provides following scheme:
A kind of rubber mold cold runner system, comprise lower bolster, the upper reaches guidance tape, dirty guidance tape, thermal insulation board, it is characterized in that: described lower bolster is fixedly mounted on the base, be installed with cope match-plate pattern on the described lower bolster, on described, be provided with die cavity between the lower bolster, on the described cope match-plate pattern injection nozzle is installed, the upper surface of described cope match-plate pattern is installed with thermal insulation board, be installed with dirty guidance tape and upper reaches guidance tape on the described thermal insulation board, on described, be provided with runner between the dirty guidance tape, described upper reaches guidance tape is provided with sprue bush, described sprue bush UNICOM runner, the injection nozzle of described runner UNICOM lower end.
Described dirty guidance tape is provided with two groups of cooling water channels, and one group is the cooling water channel of injection nozzle periphery design, and another group is dirty guidance tape cooling water water channel.
Described upper and lower runner plate links together by interior hexagonal holding screw, can adjust the flow that flows into each die cavity sizing material by regulating interior hexagonal holding screw.
This cold runner system is divided into 2 groups, and one group is dirty guidance tape cooling system, and another group is the injection nozzle cooling system, hexagonal holding screw in installing on the guidance tape of upper reaches.This cold runner system uniformity of temperature profile, stable, because injection nozzle adopts independent cooling system, the injection nozzle temperature is lower, easier control, it is more obvious that vulcanized rubber and rubber are distinguished.The interior hexagonal holding screw of installing on the guidance tape of upper reaches simultaneously can be regulated each die cavity sizing material injection volume of more accurate control to the flow that flows into a die cavity sizing material.Adopt the mould production efficiency of this cold runner system higher, cost is lower, and the stability of product quality is higher.
Description of drawings
Fig. 1 is structural representation of the present invention.
The specific embodiment
Referring to accompanying drawing, a kind of rubber mold cold runner system, comprise upper reaches guidance tape 1, dirty guidance tape 2, thermal insulation board 3, lower bolster 4, described lower bolster 4 is fixedly mounted on the base 5, be installed with cope match-plate pattern 6 on the described lower bolster 4, on described, lower bolster 4, be provided with die cavity 7 between 6, on the described cope match-plate pattern 6 injection nozzle 8 is installed, the upper surface of described cope match-plate pattern 6 is installed with thermal insulation board 3, be installed with dirty guidance tape 2 and upper reaches guidance tape 1 on the described thermal insulation board 3, described on, dirty guidance tape 1, be provided with runner 9 between 2, described upper reaches guidance tape 1 is provided with sprue bush 10, described sprue bush 10 UNICOM's runners 9, the injection nozzle 8 of described runner 9 UNICOM lower ends.
Described dirty guidance tape 2 is provided with two groups of cooling water channels, and one group is the injection nozzle cooling water channel 11 of injection nozzle periphery design, and another group is dirty guidance tape cooling water water channel 12.
Described upper and lower runner plate 1,2 links together by interior hexagonal holding screw 13, can adjust the flow that flows into each die cavity sizing material by regulating interior hexagonal holding screw 13.
