Abstract
The invention discloses an injection moulding process of acrylonitrile-butadiene-styrene copolymer (ABS) material pieces for an infusion apparatus. The injection process comprises the following steps of: S1, melting, S2, clamping a mould, S3, injecting, S4, cooling, S5, opening the mould, and S6, demoulding. The beneficial effects of the invention are as follows: as a hot runner injection moulding process is applied, and a heating device for heating a runner is contained in the hot runner mould, so that the runner is a molten state during the entire injection moulding period, further, the raw materials are saved, and the cost is reduced; the process provided by the invention is simple in process procedures, easy to achieve and short in the cycle time; and the product has better quality and the degree of automation is increased.
Description
Technical field
The present invention relates to injection molding technology field, particularly a kind of transfusion device ABS material part Shooting Technique.
Background technology
Injection moulding is a kind of method of industrial products production moulding.Product uses rubber injection mold and plastics injection moulding usually.Injection moulding can be divided into injection mo(u)lding die pressing and casting die.Injection moulding machine is the main former of plastic products thermoplastic or thermosetting plastics being made various shape by mould, and injection moulding is realized by injection machine and mould.
The puncture outfit of transfusion device and needle handle are made up of ABS material, at present, when producing puncture outfit and the needle handle of transfusion device, usual employing cold runner injection molding process, it is that runner material cools with product after moulding, and this runner material is disabled, has become waste material.The cold runner system of injection mo(u)lding from the nozzle of injection moulding machine, through sprue, runner, secondary runner, cast gate, to die cavity.The glue of molten condition is sent to die cavity from injection machine by cold runner system, if configuration or size improper, can produce shortly to penetrate, shrink mark, shrinkage cavity, current mark, weld mark, long period time etc. problem, cause product percent of pass on the low side.Except raw-material waste, the defect of cold runner technique also comprises makes whole process add step: after injection mo(u)lding, needs machine or workman that moulding and runner material are separated; According to the size of runner, the generation of waste material adds processing cost greatly.
Summary of the invention
The transfusion device ABS material part Shooting Technique the object of the invention is to the shortcoming overcoming prior art, provide a kind of and save material, processing step is simple, shortening cycle time.
Object of the present invention is achieved through the following technical solutions: transfusion device ABS material part Shooting Technique, and it comprises the following steps:
S1, colloidal sol, by nozzle heating temperatures to 220 ~ 240 DEG C of injection machine, be heated to 230 ~ 250 DEG C by barrel one section, barrel two sections be heated to 230 ~ 250 DEG C, barrel three sections is heated to 210 ~ 230 DEG C, barrel four sections is heated to 180 ~ 200 DEG C;
S2, matched moulds, burn close time is 2 ~ 4s
S3, injection, the ABS plastic of molten condition is expelled in mould by nozzle, injection process is divided into two stages: the injection speed of first stage is 80 ~ 90% maximal raties, the injection pressure of first stage is 100 ~ 110bar, the injection speed of second stage is 60 ~ 80% maximal raties, and the injection pressure of second stage is 90 ~ 100bar; The injection time is 1 ~ 3s;
S4, cooling, the time of cooling is 3 ~ 5s;
S5, die sinking, open time is 2 ~ 4s;
S6, the demoulding, demould time is 1 ~ 3s.
The present invention has the following advantages: the present invention adopts hot flow path Shooting Technique, and in hot runner mould, runner has heater, so runner material is all in molten condition in whole injection cycle, has saved raw material, has reduced cost; Present invention process step is simply convenient to realize, and shortens cycle time; Product quality is better; Improve automaticity.
