Abstract
The invention provides a short-period mold for a thin-wall high-temperature material. The short-period mold comprises a front mold and a rear mold, wherein the front mold comprises a front mold soleplate and a front mold plate, a plurality of front mold cores which are arranged adjacently are fixed on the front mold plate by virtue of screws, the surface of each front mold core is provided with an embedded front mold insert, each front mold core is also provided with a plurality of guide column holes, the rear mold comprises a rear mold soleplate and a rear mold plate, a plurality of rear mold cores corresponding to the front mold cores are fixed on the rear mold plate by virtue of screws, the surface of each rear mold core is provided with an embedded rear mold insert, each rear mold core is fixedly provided with a plurality of guide columns which are matched with the guide column holes, the front mold inserts are matched with the rear mold inserts to form mold cavities for injection molding, and after the guide columns stretch into the guide column holes to be positioned in a matching manner, a 0.01mm adjusting gap is formed between the outer wall of each guide column stretching into the corresponding guide column hole and the inner wall of the corresponding guide column hole. The short-period mold can be automatically adjusted and positioned after being expanded when being heated, so that a thin-wall product can be prevented from deforming and has no burrs.
Description
Technical field
The present invention relates to injection molding apparatus field, particularly relate to a kind of thin-walled high temperature material short period mould.
Background technology
Automobile uses as vehicles trip by increasing people.Except automobile steel frame body, other a big chunk parts are plastic items of injection mo(u)lding.As motor insulating trip, especially the motor insulating trip that nylon injection-molding is shaping, because its wall thickness is thin, use in prior art mold injection process, after nylon injection-molding, high temperature makes die swell, may cause front mould and rear mold mutual dislocation, thus makes the motor insulating trip after cooling forming produce the situation of distortion, overlap.Therefore, develop the motor insulation sheet mould that a expanded by heating can adjust location automatically and become problem demanding prompt solution.
Summary of the invention
The present invention seeks to solve the problems of the technologies described above, and after a kind of smart structural design, expanded by heating are provided, automatically can adjust the car thin-wall high temperature material short period mould of location.In order to achieve the above object, technical solution of the present invention is as follows:
A kind of thin-walled high temperature material short period mould, comprise front mould and rear mold, described front mould comprises front baffle plate and front template, described front template is fixed on front baffle plate, front template is screwed a plurality of front mould cores of arranged adjacent, each described front mould whose surfaces is equiped with embedded front cavity, the surface of described front cavity protrudes from the surface of described front template, each front mould core also offers several guide pillar hole, described rear mold comprises rear baffle plate and rear pattern plate, described rear pattern plate is fixed on rear baffle plate, rear pattern plate is screwed a plurality of with rear mold core that the is corresponding setting of described front mould core, each described rear mold whose surfaces is equiped with embedded rear cavity, the surface of described rear cavity protrudes from the surface of described rear pattern plate, each rear mold core is fixedly installed the guide pillar matched in several and described guide pillar hole, described front cavity matches with described rear cavity the die cavity formed for injection mo(u)lding, described guide pillar stretch into guide pillar hole match location after, stretch into the adjusting play forming 0.01mm between the guide pillar outer wall in guide pillar hole and guide pillar hole inwall.
The present invention further, described front mould core offers the water channel around described front cavity.
Further, the water channel on each adjacent front mould core is mutually through in the present invention.
The present invention further, described front template offers locating hole, the setting corresponding with the alignment pin be fixedly installed on rear pattern plate of described locating hole.
Beneficial effect of the present invention is embodied in: automatically can adjust location after mould expanded by heating of the present invention, avoids obtained thin-wall product distortion, produces overlap.
Accompanying drawing explanation
Fig. 1 is apparatus of the present invention front mould structural representation;
Fig. 2 is apparatus of the present invention rear mold structural representation.
Detailed description of the invention
Carry out clear, complete description below in conjunction with accompanying drawing by the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.
As depicted in figs. 1 and 2, thin-walled high temperature material short period mould of the present invention, comprise front mould 1 and rear mold 2, described front mould 1 comprises front baffle plate 11 and front template 12, described front template 12 is fixed on front baffle plate 11, front template 12 is fixed with by screw 3 a plurality of front mould cores 13 of arranged adjacent, each described front mould core 13 surface is equiped with embedded front cavity 14, each front mould core 13 also offers several guide pillar hole 15, described rear mold 2 comprises rear baffle plate 21 and rear pattern plate 22, described rear pattern plate 22 is fixed on rear baffle plate 21, rear pattern plate 22 is fixed with a plurality of with rear mold core 23 that the is corresponding setting of described front mould core 13 by screw 3, each described rear mold core 23 surface is equiped with embedded rear cavity 24, each rear mold core 23 is fixedly installed the guide pillar 25 matched in several and described guide pillar hole 15, described front cavity 14 matches with described rear cavity 24 die cavity formed for injection mo(u)lding, described guide pillar 25 stretch into guide pillar hole 15 match location after, stretch into the adjusting play forming 0.01mm between guide pillar 25 outer wall in guide pillar hole 15 and guide pillar hole 15 inwall.
Particularly, described front mould core, offers the water channel 16 around described front cavity 14 on 13.Water channel 16 on each adjacent front mould core 13 is mutually through.Described front template 12 offers locating hole 17, described locating hole 17 and the corresponding setting of alignment pin 27 be fixedly installed on rear pattern plate 22.
When apparatus of the present invention use, by the guiding matched moulds of alignment pin 27 and locating hole 17, then by injecting glue, cooling, shaping, motor insulating trip product can be obtained after die sinking.Apparatus of the present invention are for the thin cycle product design of high temperature short material wall, front and back film adopts and independently exposes die, namely do not arrange spacing framed, automatically location can be adjusted by the 0.01mm adjusting play formed between guide pillar 25 outer wall and guide pillar hole 15 inwall after mould expanded by heating, thus ensure the precision of mold cavity, avoid obtained deformation of products, produce overlap.
