Abstract

The invention provides a multi-cavity mold. The mold comprises an upper die, a plurality of upper mold inserts fixed in the upper die, a lower die, a plurality of lower mold inserts fixed in the lower die and a plurality of annular flow channels communicated with adjacent mold cavities, wherein each upper mold insert is aligned with each lower mold insert to form a mold cavity for casting a molded product; the upper die comprises a main flow channel; the lower die comprises a plurality of branched flow channels which correspond to the main flow channel and are communicated with each mold cavity and the main flow channel; and the annular flow channels are used for improving the fluidity of materials to be molded of the mold. The materials to be molded are injected into corresponding mold cavities through the main flow channel and each branched flow channel and then are cooled and molded to form the molded product. The plurality of annular flow channels communicated with the adjacent mold cavities are used for balancing the pressure and temperature differences of the adjacent mold cavities, so that the cooled molded product meets the requirements of dimensional tolerances.

Description

Multi-cavity mold
Technical field
The present invention relates to a kind of mould, relate in particular to a kind of multi-cavity mold.
Background technology
Ejection forming technique is meant material to be formed, is heated to molten condition, under the promotion of ejaculator screw rod or plunger, enters in the die cavity of mould the hardening by cooling moulding through the running gate system of nozzle and mould.
Yet, when utilizing multi-point mould jetting mold casting product,, thereby can not satisfy the requirement of precision because multi-cave mould internal temperature and pressure gap make the dimensional discrepancy of cooling off the aftershaping product greater than a preset value.As be applied to the camera eyeglass of digital camera, video camera, the mould of its casting usefulness generally includes sprue, the runner of 8 or 16 die cavitys and corresponding connection die cavity, material to be formed successively in sprue, runner flow into corresponding die cavity, therefore once plastic 8 or 16 eyeglasses.
Summary of the invention
In view of this, be necessary to provide a kind of multi-cavity mold, make that the moulding product cooling back dimensional discrepancy in the multi-cave mould can satisfy required precision.
This multi-cavity mold, it comprises a patrix, is fixed in a plurality of upper cores, the counterdie in the patrix and is fixed in the interior a plurality of dies down of counterdie, each upper cores and each die down align the die cavity that forms mould model product usefulness, this patrix comprises a sprue, this counterdie comprises the corresponding a plurality of runners that are communicated with each die cavity and sprue of sprue, material to be formed cooling forming after sprue, each runner are injected corresponding die cavity is the moulding product, and this mould also comprises the circulation road that is communicated with adjacent die cavity.
This mould has increased the circulation road that is communicated with adjacent die cavity, and then has increased the flowability of whole die cavity, makes that the moulding product after the moulding satisfy required required precision.

The specific embodiment
See also Fig. 1 and Fig. 2, it is respectively the stereogram and the exploded view of a better embodiment multi-cavity mold 100.This mould 100 comprises a patrix 10, the fixedly a plurality of upper cores 20 in the patrix 10, a counterdie 30 and fixing a plurality of dies 40 down in the counterdie 30, and each upper cores 20 and each die 40 down align the die cavity that formation is molded as material to be formed moulding product usefulness.In the middle of present embodiment, material to be formed is plastics or glass, and the quantity of upper cores 20 and following die 40 is 8 or 16, makes the once plastic 8 or 16 moulding product of this mould 100, and following is that example describes with plastic 8 moulding product once.
See also Fig. 3, be the explosive view of once plastic 8 moulding product moulds 100 shown in Figure 1.A sprue 11 and 8 fixing holes 12 are offered in the surface of patrix 10 relative counterdies 30.Sprue 11 is for running through the through hole of patrix 10, is used to flow through and injects material to be formed in the die cavitys of upper cores 20 and the 40 common formation of following die.The blind hole of 8 fixing holes 12 for offering around sprue 11 is with the upper cores 20 that fixes.Patrix 10 also offers the first circulation road 13, is used to be communicated with adjacent fixed hole 12, makes the material flowability to be formed of injecting die cavity increase.
Upper cores 20 is for inserting and being fixed in column in the fixing hole 12, and it exposes end face is forming surface 21, and forming surface 21 circumferential edge offer two relative breach 22, are used for being communicated with the first circulation road 13.
Counterdie 30 is roughly identical with patrix 10 shapes, offers 8 runners 33 of 31,8 fixing holes 32 in cold burden hole and corresponding connection cold burden hole 31 and each fixing hole 32 on the surface of its relative patrix 10.Cold burden hole 31 over against and to be communicated with 11,8 fixing holes 32 of sprue of patrix 10 relative with the fixing hole 12 of patrix 10.In the middle of present embodiment, the cross section of runner 33 is semicircle, and material to be formed and injecting in the corresponding die cavity is used to flow through.
The second circulation road 34 that matches is offered in the first circulation road of offering on the counterdie 30 corresponding patrixes 10 13.In the middle of present embodiment, the first circulation road 13 and the second circulation road 34 are measure-alike semicircle duct, and the therefore closed cross section that forms is circular circulation road.
Following die 40 is for inserting in the said fixing hole 12 and fixing column, it comprises a forming surface 41 and two relative circulation mouth 42 and the diffluence pass 43 that are opened in forming surface 41 circumferential edge, circulation mouth 42 is used for being communicated with adjacent following die 40 by the second circulation road 34, and diffluence pass 43 is used for being communicated with cold burden hole 31 by runner 33.
Please further consult Fig. 4, the arrow direction is injected mould 100 among liquid material to be formed such as the figure, after sprue 11 flows into cold burden hole 31, in runner 33 flows into 8 die cavitys of upper cores 20 and 40 formation of following die.The first circulation road 13 and the 34 closed circulation roads that form, the second circulation road have effectively increased the flowability of moulding material between each die cavity, have reduced to lead mutually the pressure and temperature difference of die cavity, finally make the yield of cooled moulding product rise.
