Mould and the plastic screw thereof of implementing making plastic screw of the present utility model, have following beneficial effect: due to by screw axis along its length by its dimidiation, and on fixed half and moving half, realize respectively; Meanwhile, the fixed half and moving half due to its mould is all to process respectively corresponding head unit and double-screw bolt unit again, obtains above-mentioned dynamic model and cover half connecting together.Be equivalent to by one comparatively the Task-decomposing of load be two comparatively simple tasks, and can not reduce whole precision.So the making of its mould is comparatively simple, difficulty is little, consuming time less.
Accompanying drawing explanation
Fig. 1 is the cross-sectional view that the utility model is made dynamic model in the mould of plastic screw and plastic screw embodiment thereof or cover half;
Fig. 2 is the structural representation of injection moulding screw in described embodiment.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is described further.
As shown in Figure 1, in the mould and plastic screw embodiment thereof of making plastic screw of the present utility model, the injection mold that this makes plastic screw, comprises fixed half and moving half, in the present embodiment, in the structure relevant to the present embodiment, cover half and also little with the difference of dynamic model, is only to have difference in the details of screw thread, so, in the present embodiment, only with a kind of being described wherein.In the following description, all take cover half as object.Certainly, due to the particularity of fixed half and moving half in the present embodiment, while in fact description being below put on dynamic model, be also appropriate.In the present embodiment, on the land area of fixed half and moving half, there is respectively corresponding, identical shaped depression, the shape (comprising its profile) of half plastic screw that these depressions are cut open along its length axes direction for the plastic screw in the present embodiment; Like this, after fixed half and moving half matched moulds, the depression on its land area constitutes the die cavity identical with plastic screw shape; In general, a screw comprises that head is connected with head and its outer surface certain position arranges threaded double-screw bolt, and its head has certain shape, for example, and hexagon or circle etc.In the present embodiment; on outer surface due to double-screw bolt, be provided with along its length the screw thread that is extended to described double-screw bolt terminal (that one end not being connected with the head of screw) by screw head and described Stud connection place, so be provided with equally along its length in the dynamic model of this mould or the part of the double-screw bolt in the depression on cover half the screw thread that is extended to described double-screw bolt terminal (that one end not being connected with the head of screw) by screw head and described Stud connection place.Only the screw thread on dynamic model is different from the screw position on cover half, and this two parts screw thread is exactly the complete screw thread of this screw altogether.
In the present embodiment, (following description be take cover half as example to cover half, but dynamic model is except above-mentioned screw position, and all the other are all identical with cover half with part relevant in the present embodiment, do not repeat them here) comprise respectively the head unit 1 and the double-screw bolt unit 2 that after processing, link together; Cover half head unit 1 is identical with the concave shape of dynamic model head unit (not shown), is respectively the shape of plastic screw head half (half that axis is along its length cut open); Cover half double-screw bolt unit 2 is corresponding with the concave shape of dynamic model double-screw bolt unit (not shown), is respectively second half shape of a half-sum that described plastic screw double-screw bolt cuts open along its length.In the present embodiment, on cover half head unit 1, be provided with the depression 11 that represents screw head, and on cover half double-screw bolt unit 2, be provided with the depression 21 that represents double-screw bolt.In the present embodiment, cover half head unit 1 and double-screw bolt unit 2 are located and are welded together by the positioner (referring to 12 in Fig. 1 and 13) arranging before processing afterwards in the depression that is processed to form its design respectively.Because the depression on dynamic model and cover half is all respectively the shape of head and double-screw bolt to be processed respectively, greatly reduced difficulty of processing, make its machining accuracy higher.Meanwhile, due to by positioner by two part location and installation of dynamic model or cover half together, make this mould also not reduce the precision of its head and double-screw bolt position.So, shorter when its Mould Machining is comparatively simple and good.
As shown in Figure 1, in the present embodiment, positioner comprises a plurality of a plurality of locating holes 13 that are separately positioned on the locating dowel 12 on cover half head unit 1 and are arranged on cover half double-screw bolt unit 2.On the contact-making surface that these positioners are all arranged on two parts while installing, the position of above-mentioned locating dowel 12 and locating hole 13 is mutually adaptive, sets in advance.When connecting this two parts, above-mentioned locating dowel 12 enters after locating hole 13, can guarantee that cover half head unit 1 and double-screw bolt unit 2 accurately dock, and obtain qualified injection moulding screw.Certainly, in above-mentioned situation, be that locating dowel 12 is set on head unit 1, locating hole 13 is set on double-screw bolt unit 2, still, contrary situation arranges locating dowel on double-screw bolt unit 2, on head unit 1, locating hole is set and also sets up; Corresponding locating dowel and locating hole are set respectively on double-screw bolt unit 2 and head unit 1, and (on a unit, existing locating dowel also has locating hole, another unit is also like this, only in the corresponding place that locating dowel is set with an above-mentioned unit, locating hole is set, in the place that locating hole is set corresponding to an above-mentioned unit, locating dowel is set) be also feasible.Meanwhile, the positioner above dynamic model is also as above.
In addition, the position arranging due to injection mold feed mouth (the plastic raw materials of fusing enters the position of die cavity) is more crucial, and the product that discharging opening should be preferably has the less loft that goes out that goes out loft or do not affect outward appearance.So, in the present embodiment, the injection moulding charging aperture of this mould is arranged on cover half, be positioned at the junction of cover half head unit 1 and cover half double-screw bolt unit 2.The impact that is subject to out loft that is arranged so that product like this drops to minimum.
In the present embodiment, also relate to a kind of injection moulding screw that uses above-mentioned Mold Making, the structure of this screw refers to Fig. 2.In Fig. 2, this screw comprises head and the double-screw bolt linking together, and is provided with along its length the screw thread that is extended to double-screw bolt terminal (being the one end not being connected with screw head in the double-screw bolt of screw) by screw head and Stud connection place on the outer surface of double-screw bolt.In the present embodiment, screw head comprises head and the round platform that is connected, that its size is greater than above-mentioned with above-mentioned head that it is shaped as hexagonal, column, described round platform also with above-mentioned Stud connection, whole screw is become one.In the present embodiment, the diameter of above-mentioned double-screw bolt is 8 millimeters, and its length is 50 millimeters.
The above embodiment has only expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
