Abstract
The invention provides a vacuum positioning mold for injection molding of a large-size insert. The mold comprises a mold core, wherein a spring positioning structure is arranged on the mold core and is used for clamping a positioning insert which is embedded into the metal insert. According to the vacuum positioning mold for injection molding of the large-size insert, a positioning hole is formed in the metal insert, a threaded positioning insert corresponding to the positioning hole is designed on the mold, the insert can be conveniently inserted and ejected into the mold due to the inclined surface design of the insert, and in addition, due to the design of a ball groove surface on the insert, a ball insert column is ejected into the groove by the compressed spring to position the insert inserted into the mold so as to ensure that the insert is positioned in the mold in a vacuum manner; the insert can be accurately put into the mold and fixed in vacuum, and does not deform and move in the injection molding process, so that the surface of the insert can be uniformly wrapped, and the surface quality of the insert is improved.
Description
Technical field
The present invention relates to plastics injection mould, be specifically related to a kind of insert injection moulding vacuum jig.
Background technology
Along with the raising of people's living standard, plastic products application is in daily life more and more extensive.Major part plastics resistance to corrosion is strong, light weight, insulation, durable, and low cost of manufacture.Therefore, insert injection moulding technology also extensive use thereupon.
Insert-molding is resin by injection after the different material inserts loading preparation in mould in advance, and the material of melting and inserts engagement cure, make the forming method of integration product.During the coating plastic of inserts border, need inserts vacuum to be placed in a mold in advance, thus, the vacuum localization method of inserts becomes the key issue of insert injection molding.
Summary of the invention
For prior art Problems existing with not enough, technical problem to be solved by this invention is, a kind of large-scale insert injection moulding vacuum jig is provided, inserts is accurately placed in mould, and can vacuum fix, ensure that in injection moulding process, inserts can not be out of shape and be shifted, thus guarantee that surface uniform is plastic, improve product surface quality.
For solving the problems of the technologies described above, the present invention takes following technical scheme, and a kind of large-scale insert injection moulding vacuum jig, it comprises core, and core arranges spring locating features, and spring locating features blocks the location mold insert be embedded in metal insert.
Above-mentioned large-scale insert injection moulding vacuum jig, spring locating features comprises the edge post mold insert be arranged on core, arranges spring driven bulb edge post in edge post mold insert, and bulb edge post blocks location mold insert.
Above-mentioned large-scale insert injection moulding vacuum jig, mold insert upper end, location is embedded in metal insert, and mold insert lower end, location arranges bulb groove, and it is interior and fixing that bulb edge post is stuck in bulb groove.
Above-mentioned large-scale insert injection moulding vacuum jig, mold insert upper end, location embeds in the locating hole in metal insert.
Above-mentioned large-scale insert injection moulding vacuum jig, mold insert upper end, location is threaded with the locating hole threaded engagement in metal insert.
Above-mentioned large-scale insert injection moulding vacuum jig, location mold insert lower end side shape is wedge shape.
Above-mentioned large-scale insert injection moulding vacuum jig, core is also arranged the positioning table of fixing metal inserts.
Above-mentioned large-scale insert injection moulding vacuum jig, core is also arranged the thimble releasing metal insert.
Tool of the present invention has the following advantages and Advantageous Effects:
1, inserts is accurately placed in mould by the present invention, and can vacuum fix.In addition, provide a kind of inserts jig structural design reliably, ensure that in injection moulding process, inserts can not be out of shape and be shifted, thus guarantee that surface uniform is plastic, improve product surface quality.
2, the present invention arranges locating hole at metal insert, corresponding mould designs screw thread location mold insert, inclined design on mold insert conveniently can be ground into mould and be ejected depanning, in addition, on mold insert the design of bulb groove surface can make mold insert grind mould rear spring compression bulb edge capital enter in groove to locate inserts, can ensure inserts in a mold vacuum location.Large-scale insert injection molding method provided by the invention designs many places positioning table and locating dowel in a mold, can prevent from causing inserts to be out of shape or displacement in injection moulding process because injection pressure increases, thus guarantees that plastic uniform is coated.

Detailed description of the invention
As shown in the figure, the one large-scale insert injection moulding vacuum jig of the present embodiment, it comprises core 9, and core 9 arranges spring locating features, and spring locating features blocks the location mold insert 4 be embedded in metal insert 1; Spring locating features comprises the edge post mold insert 8 be arranged on core 9, and arrange the bulb edge post 6 that spring 7 drives in edge post mold insert 8, spring 7 cover has protecting sheathing, and bulb edge post 6 blocks location mold insert 4; Mold insert 4 upper end, location is embedded in metal insert 1, and mold insert 4 lower end, location arranges bulb groove 5, and it is interior and fixing that bulb edge post 6 is stuck in bulb groove 5; Mold insert 4 upper end, location embeds in the locating hole 3 in metal insert 1; Mold insert 4 upper end, location is threaded with locating hole 3 threaded engagement in metal insert 1; Location mold insert 4 lower end side shape is wedge shape; Core 9 is also arranged the positioning table 11 of fixing metal inserts 1; Core 9 is also arranged the thimble 10 releasing metal insert 1.
The concrete processing use procedure of the present embodiment is as follows:
Symmetrical machining locating hole 3 on metal insert 2, corresponding location mold insert 4 is also designed with screw thread locating dowel nose shape, the two sides of location mold insert is designed with bulb groove 5, in edge post mold insert 8, design bulb edge post 6 in mould head into location mold insert bulb groove 5 by the compression of spring 7, metal insert 1 is located, ensures vacuum location under mold closed condition; Location mold insert 4 is designed to 5 ° of inclined-planes in two sides in addition, that is: locating mold insert 4 lower end side shape is wedge shape, conveniently can grind in core 9 and eject depanning, in injection molding process, metal insert 1 is positioned by positioning table 11, causes metal insert 1 be out of shape or be shifted in order to prevent because injection pressure increases; After injection mo(u)lding terminates, die sinking obtains plastic plastic 2, drives thimble 10 to be ejected by plastic plastic 2, ejected in the lump by location mold insert 4 simultaneously by injection molding machine.
Specifically, in the medium-and-large-sized insert injection molding procedure of the present embodiment, location mold insert 4 head threads locating dowel screws in band large-scale metal inserts 1, assembly is loaded in core 9, when locating mold insert loading and putting in place, bulb is inlayed post 6 and is ejected by spring 7, heads in location mold insert bulb groove 5 and is located by inserts, thus ensures that metal insert 1 can vacuum be located in a mold; Reserved certain interval between positioning table 11 and metal insert 1 in mould, prevent metal insert 1 because of heat expansion mold damage, the effect simultaneously playing fixing metal inserts 1 prevents because injection pressure increases and causes metal insert 1 be out of shape or be shifted, thus guarantees that plastic uniform is coated; After injection mo(u)lding terminates, obtain coated plastic 2, injection molding machine drives thimble 10 to be ejected by coated plastic 2, and now, bulb edge post 6 retreats, and spring 7 compresses, and location mold insert 4 is with the depanning of coated plastic 2; After obtaining product, location mold insert 4 is loaded in next metal insert 1 and enters next molding cycle.
