Description
Technical Field
The utility model relates to a device of moulding plastics, concretely relates to injection blow molding flow distribution plate.
Background
Injection molding is a common method for manufacturing industrial products, and generally, plastic or rubber is melted and then injected into a mold through an injection molding machine. For a plurality of products which are simultaneously injected and molded, if the melted materials are extruded into a mould from an injection molding machine, the pressure of raw materials close to the extrusion port of the injection molding machine is larger, and the pressure of raw materials far away from a plurality of outlet positions of the injection molding machine is smaller, so that the product quality close to the injection port is different from that far away from the injection port, and the product quality is influenced.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide an injection blow molding flow distribution plate can effectively solve the inhomogeneous problem of pressure in distributing the mould from the raw materials of injection molding machine extrusion opening.
In order to solve the technical problem, the utility model discloses a realize through following technical scheme: the utility model provides an injection blow molding flow distribution plate, includes the plate body, moulds plastics the import and set up the first subchannel and two second subchannels of moulding plastics in the plate body, the first subchannel of moulding plastics is followed plate body length direction sets up, the import of moulding plastics is opened on the plate body and with the first subchannel that moulds plastics communicates with each other, two the second subchannel of moulding plastics coaxial line and all with the first subchannel parallel arrangement of moulding plastics, first subchannel and every of moulding plastics all be equipped with the intercommunication way between the subchannel, every the second subchannel of moulding plastics all opens and moulds plastics the export with communicating two at least in the external world, and all the export of moulding plastics all are located the coplanar of plate body.
Furthermore, each second injection molding sub-runner is provided with three injection molding outlets communicated with the outside, one injection molding outlet is coaxial with the communication channel, and the diameter of the injection molding outlet is smaller than that of the communication channel; can connect a plurality of moulds simultaneously or accelerate the speed of moulding plastics to same mould, but can guarantee again that the export of moulding plastics of both sides is unanimous basically with the export pressure of moulding plastics in the middle of, one of them is moulded plastics the export and is said coaxially with the intercommunication, conveniently to the processing of intercommunication way, and the diameter of the export of moulding plastics is less than the diameter that the intercommunication was said, prevents directly from the export of moulding plastics of the raw materials that flows from the intercommunication way and flows, utilizes the bore difference, adjusts the second and moulds plastics the pressure in the subchannel.
Furthermore, the diameter of the injection molding outlet is 0.75-0.8 times of the diameter of the communication channel, the extrusion line efficiency of the injection molding outlet is reduced when the ratio is too small, and the pressure difference of the injection molding outlets in different positions is increased when the ratio is too large.
Furthermore, the plate body is also provided with an access hole which is communicated with the first injection molding sub-runner and is coaxial with the communication channel; can repair the intercommunication way when making the intercommunication way through the inspection hole, prevent that there is the burr to produce, but also the later stage can be maintained the intercommunication way.
Furthermore, the three injection molding outlets are arranged on a straight line, the distances from the injection molding outlets at two ends to the injection molding outlet in the middle are equal, and the injection molding outlet in the middle is coaxial with the communication channel; the three injection molding outlets are in butt joint with the mold on the same straight line, the injection molding outlets at two ends are equidistant to the injection molding outlet in the middle, and the injection molding outlet in the middle is coaxial with the communication channel, so that the extrusion pressure of the injection molding outlets at two ends is consistent.
Furthermore, the diameter of the injection molding inlet is equal to the diameter of the first injection molding sub-channel and is larger than the diameter of the communicating channel, the diameter of the injection molding inlet is equal to the diameter of the first injection molding sub-channel, so that raw materials entering the first injection molding sub-channel are dispersed into the first injection molding sub-channel as soon as possible and are larger than the diameter of the communicating channel, the raw materials entering the first injection molding sub-channel are prevented from flowing out of the communicating channel completely, certain pressure is kept in the first injection molding sub-channel, and accordingly the pressure of the raw materials flowing out of the two communicating channels can be guaranteed to be consistent.
Furthermore, the diameter of the first injection molding sub-channel is 1.2-1.3 times of the diameter of the communicating channel, the pressure in the two communicating channels cannot be balanced due to too small ratio, and the pressure in the first injection molding sub-channel is too large due to too large ratio, so that the extrusion efficiency is reduced.
Furthermore, the injection molding inlet and the injection molding outlet are respectively formed in two opposite planes of the plate body, and the injection molding inlet and the injection molding outlet are respectively formed in the opposite planes of the plate body, so that the injection molding machine and the mold have more placing spaces, and the interference is avoided.
Compared with the prior art, the utility model has the advantages that: through set up two subchannel and a plurality of export of moulding plastics on the flow distribution plate, solve at present from the injection molding machine extrusion mouth raw materials distribution to the uneven problem of pressure in the mould. Set up the first subchannel of moulding plastics and two seconds in the plate body and mould plastics the subchannel to it has two at least exports of moulding plastics all to open on every second subchannel of moulding plastics, it disperses pressure through the subchannel of moulding plastics behind the flow distribution plate to get into the raw materials, the raw materials pressure dispersion that the subchannel of moulding plastics that utilizes different positions will get into the flow distribution plate is even, thereby make every raw materials pressure of moulding plastics the export outflow differ by a little, and then the uniformity when promoting product plastic forming, ensure product quality. And two second subchannel coaxial lines of moulding plastics and all with the first subchannel parallel arrangement of moulding plastics are favorable to reducing the processing degree of difficulty, do benefit to the distance of controlling the first subchannel of moulding plastics to two second subchannel of moulding plastics simultaneously, let two second subchannel of moulding plastics can extrude the raw materials simultaneously. And all export of moulding plastics all are located the coplanar of plate body, are difficult to leave the gap when butt joint mould, realize the steady butt joint with the mould.
