Abstract
The utility model discloses a key cap forming die, the stamping die comprises an upper template and a lower template, become the die cavity between cope match -plate pattern and the lower bolster, be provided with flow channel hole on the cope match -plate pattern, flow channel hole includes the hole body and the lower hole body, the cross section of going up the hole body from top to bottom reduces gradually, the cross section of the lower hole body is from top to bottom crescent, goes up the lower extreme of the hole body and the upper end intercommunication of the lower hole body, and the lower extreme and the one -tenth die cavity of the lower hole body feed through. The key cap forming die of this structure has and walks to glue smoothly, can not appear jam and the little advantage of loss of pressure.
Description
Technical field
This utility model relates to a kind of keycap mould.
Background technology
Injection mold is the important process equipment producing various industrial products, along with plastic mould design industry develop rapidly and plasthetics in aviation, boat too, the popularization and application of the industrial department such as electronics, machinery, boats and ships and automobile, product is more and more higher to the requirement of mould, and traditional plastic mould method for designing cannot adapt to model change and propose high-quality requirement.Computer aided engineering technology become these weak links in plastic cement products exploitation, Design of Dies and Product processing maximally effective by way of.
In existing keycap mould, walk glue when existing into glue and have some setbacks blocking, defect that the pressure loss is big even occur, cause that product lacks material, product fraction defective regularly higher.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of keycap mould so that it is has that glue is smooth and easy, have blocking and advantage that the pressure loss is little.
This utility model solves the problems referred to above by techniques below means: a kind of keycap mould, including cope match-plate pattern and lower bolster, forming cavity between described cope match-plate pattern and lower bolster, cope match-plate pattern is provided with runner hole, described runner hole includes hole body and lower hole body, and the cross section of described upper hole body is from top to bottom gradually reduced, and the cross section of described lower hole body is from top to bottom gradually increased, the lower end of upper hole body connects with the upper end of lower hole body, and the lower end of lower hole body connects with forming cavity.
Further, the degree of depth of described upper hole body is 8-15 times of the lower hole body degree of depth.
Further, described runner hole and cope match-plate pattern removably connect.
Further, described upper hole body is provided with transition cambered surface with the junction of lower hole body.
Further, it is provided with heat radiation material layer between described runner hole and cope match-plate pattern.
Further, described upper hole body wall being vertically set side by side with polylith drainage piece diagonally downward, described drainage piece upper end is hinged with upper hole body wall, is provided with spring between drainage piece and upper hole body wall.
The beneficial effects of the utility model: keycap mould of the present utility model, including cope match-plate pattern and lower bolster, forming cavity between described cope match-plate pattern and lower bolster, cope match-plate pattern is provided with runner hole, described runner hole includes hole body and lower hole body, and the cross section of described upper hole body is from top to bottom gradually reduced, and the cross section of described lower hole body is from top to bottom gradually increased, the lower end of upper hole body connects with the upper end of lower hole body, and the lower end of lower hole body connects with forming cavity.The keycap mould of this structure, has that glue is smooth and easy, does not have blocking and advantage that the pressure loss is little.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, this utility model is further described.
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below with reference to accompanying drawing, this utility model is described in detail, as shown in Figure 1: a kind of keycap mould, including cope match-plate pattern 1 and lower bolster 2, forming cavity 3 between described cope match-plate pattern and lower bolster, cope match-plate pattern is provided with runner hole, described runner hole includes hole body 41 and lower hole body 42, the degree of depth of described upper hole body is 8-15 times of the lower hole body degree of depth, the cross section of described upper hole body is from top to bottom gradually reduced, the cross section of described lower hole body is from top to bottom gradually increased, the lower end of upper hole body connects with the upper end of lower hole body, and the lower end of lower hole body connects with forming cavity.The keycap mould of this structure, on the one hand, in glue (injection raw material referred to molten condition) entrance during hole body, the cross section of upper hole body is from top to bottom gradually reduced, can be gradually reduced into glue laminated power, shortening forming time, it is unlikely to the pressure loss excessive, meanwhile, flows through in the process of hole body, pressure is gradually increased, glue can be made more smooth and easy when passing through, and when glue flows into lower hole body section, the cross section of lower hole body is gradually increased, can further such that to walk glue smooth and easy, it is to avoid blocking occurs.
As the further improvement of technique scheme, described runner hole and cope match-plate pattern removably connect, and are provided with heat radiation material layer 5 between described runner hole and cope match-plate pattern.In injection moulding process, runner hole directly contacts with injection raw material, has occurred abrasion or thermal deformation etc. to damage, when runner hole is damaged, take off the runner hole more renewed, whole set of die need not be changed, be conducive to saving cost, in addition, it is provided with heat radiation material layer between runner hole and cope match-plate pattern, can be dispelled the heat in runner hole, the thermal deformation in runner hole can be slowed down, further increase service life.
As the further improvement of technique scheme, the junction of described upper hole body and lower hole body is provided with transition cambered surface.Transition cambered surface can make injection raw material more smooth and easy when flowing through hole body with the junction of lower hole body.
As the further improvement of technique scheme, described upper hole body wall being vertically set side by side with polylith drainage piece 6 diagonally downward, described drainage piece upper end is hinged with upper hole body wall, is provided with spring 7 between drainage piece and upper hole body wall.When injection raw material flows through hole body, deviate from spring one side to contact with drainage piece, drainage piece plays drainage on the one hand, make away glue more smooth and easy, on the other hand, when upper hole body inwall bondd glue or glue circulation excessive easy occur blocking time, glue can extrude drainage piece compression spring, thus increasing the sectional area of glue circulation passage, to guarantee that glue flows through smoothly, further avoid blocking, when glue circulation is moderate, drainage piece is in normal condition, and spring does not deform upon, in order to guarantee pressure when glue circulates.
What finally illustrate is, above example is only in order to illustrate the technical solution of the utility model and unrestricted, although this utility model being described in detail with reference to preferred embodiment, it will be understood by those within the art that, the technical solution of the utility model can be modified or equivalent replacement, without deviating from objective and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
