The purpose of this utility model is to provide a kind of electric motor car gusset plate injection mold core runner symmetrical mechanism, to meet the Production requirement of the large-scale sheet plastic with symmetrical feature.
In order to address the above problem, the utility model adopts following technical scheme:
A kind of electric motor car gusset plate injection mold core runner symmetrical mechanism, described mould comprises cope match-plate pattern, lower bolster, thimble, thimble fixed head, lower roof plate, mould pin, lower compound plate, lead, runner, described cope match-plate pattern is positioned at described lower bolster top, the lower surface of described cope match-plate pattern is provided with die cavity, the lower end of described thimble is fixed on described thimble fixed head, described mould pin is connected between described lower bolster and described lower compound plate, described lower roof plate is positioned at described thimble fixed head below, described lower roof plate, thimble fixed head can be located between described lower bolster and described lower compound plate up or down, described lower bolster comprises and is located thereon surperficial core, described runner is positioned at the middle part of described core, described lead is arranged at described cope match-plate pattern, in the pilot hole in lower bolster bight, wherein, described core is that symmetrical structure is with two large-scale sheet plastics of production structure symmetry, the both sides of described runner are provided with the branch flow passage for delivery of molten plastic, to produce two large-scale sheet plastics simultaneously, the centre of described runner arranges cast gate, upper surface at described lower bolster, the position that described pilot hole is set is a boss, correspondingly, lower surface at described cope match-plate pattern, the position that described pilot hole is set is a gap, the exterior contour of described boss is identical with the in-profile of described gap, so that described boss embeds in described gap closely.
Preferably, in a kind of preferred embodiment of said mechanism, described runner comprises three sections, and described runner integral body is Y-shaped, and the both sides of a section of described runner are equipped with branch flow passage, with simultaneously to the both sides transporting molten plastics of described core; Two sections of all the other of described runner are extended along the inside edge of described core respectively, to be respectively used to form a large-scale sheet plastic.
Analyze knownly, in order to cater to the symmetrical feature of plastic, produce two plastic parts simultaneously, the core on lower bolster of the present utility model is symmetrical structure.And runner is also symmetrical structure.Excessive in order to solve mould volume, larger problem is impacted in lead location, in pilot hole position, the utility model respectively in the Position Design of cope match-plate pattern, lower bolster boss, gap structure.
Accompanying drawing explanation
Fig. 1 is the perspective view of the mould (not comprising cope match-plate pattern) with the utility model embodiment;
Fig. 2 is the plan structure schematic diagram of lower bolster with the mould of the utility model embodiment;
Fig. 3 is the perspective view with the plastic parts 1 that the mould of the utility model embodiment produces.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details.
As Figure 1-Figure 2, the mould with the utility model embodiment comprises cope match-plate pattern (not shown), lower bolster 2, thimble (not shown), thimble fixed head 5, lower roof plate 6, mould pin 3, lower compound plate 4, lead (not shown, but show the pilot hole 22 on lower bolster 2 that is positioned at that holds lead), runner 7.
Mould shown in Fig. 1-Fig. 2 is for the production of the large-scale sheet plastic 1 shown in Fig. 3, and this plastic 1 is an electric motor car gusset plate, and area is larger, and is symmetrical structure, and a pair of plastic 1 of symmetrical configuration is for being fixed on the both sides of an autobicycle.
Cope match-plate pattern is positioned at lower bolster 2 tops, and the lower surface of cope match-plate pattern is provided with die cavity, and the upper surface of lower bolster 2 is provided with core 20, and core and die cavity are in conjunction with forming plastic 1 for injection moulding.The lower end of thimble is fixed on thimble fixed head 5, and mould pin 3 is connected between lower bolster 2 and lower compound plate 4, and lower roof plate 6 is positioned at thimble fixed head 5 belows.Lower roof plate 6, thimble fixed head 5 can be located between lower bolster 2 and lower compound plate 4 up or down.Runner 7 is positioned on core 20, and lead is arranged at the pilot hole of cope match-plate pattern, in the pilot hole 22 in lower bolster 2 bights.
Core 20 is symmetrical structure, to produce two large-scale sheet plastics 1 with symmetrical configuration feature.Runner 7 is located at middle part along the length direction of core 20, and cast gate 8 is located at the centre of runner 7.In order to inject sufficient molten plastic between core 20, die cavity, the both sides of runner 7 are provided with the branch flow passage 71 for delivery of molten plastic, to produce two large-scale sheet plastics 1 simultaneously.In the upper surface bight of lower bolster 2, the position that pilot hole 22 is set is a boss 21, correspondingly, lower surface at cope match-plate pattern, the position that pilot hole is set is a gap, and the exterior contour of boss 21 is identical with the in-profile of gap, so that boss 21 embeds in gap closely.
Because plastic 1 area is larger, so the volume of cope match-plate pattern, lower bolster 2 is also larger, if only provide guiding with lead, when matched moulds, to lead, may produce larger impact, so the present embodiment has been provided with the structures such as boss 21, gap.
Because the inside edge of plastic 1 is arc, on core 20, extend to contrary both direction the inside edge of two plastics 1, this curved edge is away from runner 7, and for fear of produce the problem of molten plastic deficiency at plastic 1 end, the runner 7 of the present embodiment comprises three sections, as Fig. 2, runner 7 integral body are Y-shaped, and the both sides of a section of runner 7 are equipped with branch flow passage 71, with the both sides transporting molten plastics of while to core 20; All the other two sections of runner 7 are extended along the inside edge of core 20 respectively, to be respectively used to form a large-scale sheet plastic 1.
In sum, the utility model is in conjunction with the feature with the large-scale sheet plastic of symmetrical feature, improved flow passage structure, core structure, the guide frame of existing mold, thus can high-quality, high efficiency production has the large-scale sheet plastic of symmetrical configuration feature.
As known by the technical knowledge, the utility model can be realized by other the embodiment that does not depart from its Spirit Essence or essential feature.Therefore, above-mentioned disclosed embodiment, with regard to each side, all just illustrates, and is not only.All changes within the scope of the utility model or within being equal to scope of the present utility model are all included in the utility model.
