In one preferred embodiment of the utility model, further comprise that the mold core is located at lower die and intermediate die boundary two
The radius of side is respectively less than the radius positioned at lower die and intermediate die boundary.
In one preferred embodiment of the utility model, further comprise that the upper mold is equipped with stock chest, in the upper mold
Die cavity be connected to stock chest.
In one preferred embodiment of the utility model, further comprise that the upper mold is equipped with the cover board that can be dismantled.
In one preferred embodiment of the utility model, further comprise that the die holder further includes bed die, the lower die setting
On bed die, the bed die is equipped with mold core location hole, and the mold core is arranged in mold core location hole.
In one preferred embodiment of the utility model, further comprise being equipped with groove and convex around die cavity in the intermediate die
Platform.
The sucker molding die of the utility model, upper mold, intermediate die and lower die are cascading from top to bottom, two-by-two mould
The die joint of tool is the horizontal plane being laterally extended so that and sucker after molding, die parting line extend along the outer circle circumferential direction of sucker,
It easily hides, does not influence the appearance of sucker.

Specific embodiment
The utility model is described in further detail in the following with reference to the drawings and specific embodiments, so that those skilled in the art
The utility model may be better understood and can be practiced, but illustrated embodiment is not as the restriction to the utility model.
Embodiment
As shown in Figs. 1-3, present embodiment discloses a kind of sucker molding die, including upper mold 2, intermediate die 4, lower die 6, bottom
Mould 14 and mold core 8, above-mentioned upper mold 2, intermediate die 4, lower die 6 and bed die 14 are cascading from top to bottom, above-mentioned upper mold 2, in
Between be equipped with die cavity in mould 4 and lower die 6, above-mentioned upper mold 2, intermediate die 4 are penetrated through successively in the die cavity axial direction of 6 three of lower die；It is above-mentioned
Bed die 14 is equipped with mold core location hole 16, and one end of above-mentioned mold core 8 is arranged on mold core location hole 16, and other end is axial successively
The die cavity of drawing-in lower die 6, intermediate die 4 and upper mold 2 is equipped with radial clearance between above-mentioned mold core 8 and each die cavity.
Above-mentioned upper mold 2 is equipped with stock chest 10, and the die cavity in the upper mold 2 is connected to stock chest 10, in above-mentioned upper mold 2
Equipped with the cover board 12 that can be dismantled.
The molding die of more than structure, assembling in use, modulus core 8 be mounted on bed die 14 mold core location hole 16 in, with
Place lower die 6, intermediate die 4 and upper mold 2 from bottom to top successively afterwards, the material after stripping and slicing be placed in stock chest 10, then on
Molding die is integrally put into vulcanizing oven by cover board 12 after assembling, and the material in stock chest 10 melts after being heated, and is melt into
The material of fluidised form flows through the radial clearance between each die cavity and mold core 8 from top to bottom, after the material cooling and demolding in radial clearance
Form sucker.During product stripping, cover board, upper mold, intermediate die and lower die are taken successively from top to bottom, when taking out lower die, after molding
Sucker and mold core connect together and be removed, finally sucker is removed from mold core.
The interface of both more than upper mold and intermediate die forms the interface of both first die joint, intermediate die and lower die
The interface formation third die joint of second die joint, lower die and bed die is formed, three die joints are what is be laterally extended
Horizontal plane, fluidised form logistics generate die parting line when flowing through each die joint, above by design upper mold, intermediate die and lower die from upper and
Under be cascading so that sucker after molding, die parting line along sucker outer circle circumferential direction extend, easily hide, do not influence
The appearance of sucker improves the molding yield of sucker.
When designing upper mold, intermediate die, the size of lower die and bed die, consider third parting Surface Design at one of sucker
Endface, second parting Surface Design is at sucker maximum outside diameter, that is, above-mentioned mold core 8 is located at lower die 6 and intermediate die 4 is demarcated
The radius for locating both sides is respectively less than the radius for being located at 4 boundary of lower die 6 and intermediate die, and the die parting line at the second die joint is hidden at this time
Among the circular arc of sucker, the die parting line at third die joint is directly the end edge line of sucker, reduces divide to the greatest extent
Influence of the loft to sucker appearance.
Theoretically, the thickness of intermediate die is identical with the thickness of product, very thin, above-mentioned in order to improve the intensity of intermediate die
In intermediate die 4 groove 18 and boss 20 are equipped with around die cavity.
Embodiment described above is only the preferred embodiment lifted to absolutely prove the utility model, the utility model
Protection domain it is without being limited thereto.The equivalent substitute or change that those skilled in the art are made on the basis of the utility model
It changes, is within the protection scope of the utility model.The scope of protection of the utility model is subject to claims.
