Abstract
The utility model discloses a high-precision vacuum shoe sole forming mold. Upper sealing slots are formed in the outer edge of a molded cavity of a lower mold seat and are connected end to end to form a closed ring slot; the upper sealing slots surround the molded cavity by a circle; upper sealing rings are embedded into the upper sealing slots and are partially protruded from the upper surface of an upper mold seat; a plurality of vacuumizing thin holes are formed in the edge of the bottom of the molded cavity of the lower mold seat; a vacuumizing channel is formed in the lower mold seat; all the vacuumizing thin holes are respectively communicated with the vacuumizing channel. Due to the precision design, the precision of the mold is improved, so that the mold is high in sealing property and good in vacuumizing effect; after being vacuumized, a coating film can be very tightly attached to the inner wall of the molded cavity, and the service life is long.
Description
Technical field
The utility model relates to die for shoe-sole technical field, especially relates to a kind of high-precision vacuum shoe sole mould.
Background technology
In prior art, the mould of sole comprises upper bolster and die shoe, upper bolster and die shoe offer respectively die cavity, the cavity shape that the merging of upper bolster and die shoe forms is afterwards the shape of sole, toward upper bolster and die shoe or form material, upper bolster and die shoe close and close rear and keep locked mode a period of time, by compression molding, after moulding material sizing, can mold sole.Although the development of sole forming die and technology, the application of vacuum diaphragm has improved style and the quality of sole, and it need to cover an overlay film at die shoe before moulding, then vacuumizes, but, current sole vacuum mold precision is poor, and sealing property is lower, and vacuumizing effect is bad, overlay film effect is bad, often there is defect in the sole shape forming out, affects the Forming Quality of sole, is therefore necessary to be improved.
Utility model content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of high-precision vacuum shoe sole mould, and its precision is high, good seal performance, long service life.
To achieve these goals, the technical scheme that the utility model adopts is:
A kind of high-precision vacuum shoe sole mould, comprise upper bolster and die shoe, the first end of upper bolster and die shoe is hinged, die shoe the second end is provided with clamping mechanism, the land area of upper bolster and die shoe offers respectively die cavity, overlay film is covered in the end face of die shoe, the outer rim of the die cavity of die shoe offers seal groove, upper seal groove joins end to end and forms a closed annular groove, upper seal groove encloses around die cavity one, in upper seal groove, be equipped with sealing ring, the local surface of protruding at upper bolster of upper sealing ring, the edge of the bottom of the die cavity of die shoe offers some pores that vacuumize, die shoe offers evacuation passageway, respectively vacuumize pore and be communicated with respectively evacuation passageway.
Further in technical scheme, described die shoe comprises middle plate and base plate, middle plate and base plate are screwed integral, base plate is offered evacuation passageway, the outer rim of evacuation passageway offers lower seal groove cavity, lower seal groove cavity joins end to end and forms a closed annular groove, and lower seal groove cavity encloses around evacuation passageway one, is equipped with lower seal in lower seal groove cavity.
Further, in technical scheme, the edge of the die cavity of described upper bolster is provided with ventilative gap.
Further, in technical scheme, described base plate offers and vacuumizes interface, vacuumizes interface and is communicated with evacuation passageway.
Further, in technical scheme, described evacuation passageway is flat conduit.
Further in technical scheme, described in vacuumize pore and be obliquely installed, the lower end that vacuumizes pore is connected to the inside edge of evacuation passageway.
Further, in technical scheme, the second end of described upper bolster and die shoe is fixed with respectively handle, and the end face of upper bolster offers some lightening grooves.
Adopt after said structure, the advantage that compared to the prior art the utility model had is: the utility model is by accurate design, improve the precision of mould, make it have better sealing property, vacuumizing effect is better, after vacuumizing, overlay film can be close to the inwall of die cavity, long service life very snugly.
