Abstract
The invention discloses a one-time injection molding process for a double-component material. A main injection platform, and an auxiliary injection platform which are vertical to each other, and two mutually vertical screws on the main injection platform and the auxiliary injection platform are adopted; when a first material begins to be subjected to injection molding, the first material is subjected to injection molding by using the main injection platform; and when the set time is reached, the screw injects a molten material into the cavity of a mould through a nozzle and an injection molding port on the mould, then a drawn core of the inner cavity of the mould is moved under the control of an oil cylinder to ensure the screw on the auxiliary injection platform begins to perform injection molding, and finally the second material molten on the screw enters the cavity of the mould through the nozzle and the other injection molding port formed in the mould, so that the injection molding process of the two kinds of materials in the cavity of the mould can be finished. The one-time injection molding process has the advantages that: the process is easy to operate, and energy is saved; 2, the adhesion force of a produced double-component product is more than or equal to 90N/20mm, and meets the technical standard requirement of the product, and the rejection rate is low; and 3, the production capacity can be doubled.
Description
Technical field:
The present invention relates to a kind of injection moulding process, particularly a kind of two-component materials single injection-molded technology and mould therefor.
Background technology:
At present two materials are injection-moulded in the plastic rubber shaping technical field and have very general application, and the complex forming technology of existing pair of material injection moulding is used inconvenient.If any a kind of compound pair of Flow of Goods and Materials Shooting Technique, it adopts two to overlap independently screw rod control system, two screw rods are arranged, its crucial technology is that a rotatable rotating disk is arranged on moving platen, double-color mold after injection moulding has been finished for the first time, rotating disk Rotate 180 °, die cavity " 1 " forwards the position of original die cavity " 2 " to, die cavity " 2 " rotates the position of original die cavity " 1 ", carries out the injection moulding second time then.This Shooting Technique is complex structure not only, and secondary pollution takes place product easily, makes that its bonding force is little to be torn easily.And this Shooting Technique can only be produced undersized product, and production capacity is restricted.
Summary of the invention:
Purpose of the present invention just is the above-mentioned the deficiencies in the prior art of customer service, and a kind of two-component materials single injection-molded technology is provided, the production capacity that this technology is simple, easy to use, can double.
Technical scheme of the present invention is: a kind of technology of two-component materials single injection-molded, it is characterized in that: utilize vertically disposed main injection platform, auxilliary injection platform and master, orthogonal two screw rods on the auxilliary injection platform, when first kind of material begins injection moulding, at first utilize the screw rod of main injection platform to carry out injection moulding, when reaching the time of setting, screw rod is expelled to the material of fusion in the die cavity of mould by an injection hole on nozzle and the mould, loosing core of dies cavity moved under the control of oil cylinder at this moment, make the screw rod on the auxilliary injection platform begin injection moulding, second kind of material of fusion also enters mold cavity by nozzle and another injection hole of opening on mould on last this root screw rod, thereby finishes the injection process of two kinds of materials in the mold cavity.
The used mould of above-mentioned single injection-molded technology, comprise the reinforced ejecting mechanism and the mould that mould are penetrated feed, it is characterized in that: the reinforced ejecting mechanism that mould is penetrated feed is made up of vertically disposed main injection platform and auxilliary injection platform, two screw rods on main injection platform and the auxilliary injection platform are 90 degree angles, make two injection ports in the reinforced ejecting mechanism of two covers also be vertical configuration; It is corresponding with these two injection ports in vertical state respectively to have two injection holes on the mould; The core that pulls and pushes by oil cylinder control is housed in the dies cavity, and this pulls and pushes the place, composition surface that core is positioned at two kinds of materials.
Advantage of the present invention is: 1, simple, the energy savings of technological operation.2, two component product bonding force 〉=90N/20mm of Sheng Chaning meet the product technology standard-required, and percent defective is low.3, mould has two injection moulding ports, and the injection of two materials is guaranteed by system's control mould inner core pulling, makes the same die cavity of mould can finish double injection, enhances productivity.But 4, the same manufacture order component product with same model equipment, the production capacity that can double.
Description of drawings:
Fig. 1 is the structural representation of mould of the present invention.
The specific embodiment:
A kind of technology of two-component materials single injection-molded, after in a kind of plastic material in the barrel enters the material pipe that generates heat on the main injection platform, the rotation of the screw rod in the material pipe, utilize the spiral hopper on the screw rod to advance plastic material to advance to screw rod the place ahead, plastic material is after the charge tube fusing, an injection hole on nozzle and mould injects in the mold cavity, arrive the time of setting this moment, loosing core of dies cavity moved under the control of oil cylinder, make the screw rod on the auxilliary injection platform begin injection moulding, second kind of material on last this root screw rod also enters in the mold cavity by nozzle and another injection hole of opening on mould, thereby finishes the double injection process in the mold cavity.Two kinds of melts in the mold cavity through pressurize, cooling, solidifying and setting after, mould under the effect of clamping, opening mold, and by liftout attachment stereotyped goods are ejected from mould and to fall.
The mould that above-mentioned injection molding process is used comprises the reinforced ejecting mechanism and the mould that mould are penetrated feed.Mould is penetrated the reinforced ejecting mechanism of feed and be made up of vertically disposed main injection platform and auxilliary injection platform, two screw rods on main injection platform and the auxilliary injection platform are 90 degree angles, make the injection port in the reinforced ejecting mechanism of two covers also be vertical configuration; It is corresponding with these two injection ports in vertical state respectively to have two injection holes on the mould; The core that pulls and pushes by oil cylinder control is housed in the dies cavity, and this pulls and pushes the place, composition surface that core is positioned at two kinds of materials.
The design is rational in infrastructure, simple to operate, energy savings.The two component product bonding force 〉=90N/20mm that produce meet the product technology standard-required, and percent defective is low.Because mould has two injection moulding ports, the injection of two materials is guaranteed by system's control mould inner core pulling, makes the same die cavity of mould can finish double injection, enhances productivity.But the same manufacture order component product with same model equipment, the production capacity that is doubled.
