Detailed Description
In order to better understand the technical solutions, the technical solutions will be described in detail with reference to the description and the specific embodiments.
Example 1
A rubber substrate die is composed of an upper die plate and a lower die plate. Referring to fig. 1, the upper plate has an upper rubber substrate area 21, an upper burr area 22, and a first groove area 23, and the upper rubber substrate area 21 is connected to the upper burr area 22 through the first groove area 23. Referring to fig. 2 and 3, the lower mold plate has a lower rubber substrate area 11, a lower burr area 12 and a second groove area 13, the angle of the groove at the bottom of the second groove area 13 is 60 degrees, the edge of the lower rubber substrate area 11 is connected with the second groove area 13, and one side of the second groove area 13 departing from the lower rubber substrate area 11 is connected with the lower burr area 12.
When the upper template and the lower template are in sealing connection, the upper rubber substrate area 21 coincides with the lower rubber substrate area 11, the upper burr area 22 coincides with the lower burr area 12, and referring to fig. 4, the first groove area 23 is located above the second groove area 13 when viewed in the vertical direction (y direction); viewed in the horizontal direction (x direction), the position of the sharp corner at the bottom of the second recessed area 13 (the angle of the sharp corner is 30 to 60 degrees) coincides with the position of the edge of the first recessed area 23 or the position of the sharp corner at the bottom of the second recessed area 13 is 0 to 0.3mm from the edge of the first recessed area 23.
The lower rubber substrate area 11 comprises a first lower rubber substrate area 111, a second lower rubber substrate area 112 and a third lower rubber substrate area; the first lower rubber sole area 111 corresponds to the front sole position, the second lower rubber sole area 112 corresponds to the rear heel position, and the third lower rubber sole area corresponds to the arch position. The first lower rubber substrate area 111, the second lower rubber substrate area 112 and the third lower rubber substrate area are not connected with each other, but are connected with the second groove.
In the process of actually using the sole, because the stress and friction conditions of different positions of the sole are different, correspondingly, the thicknesses and the shapes of different areas in the rubber sole are different. Also, for faster burr removal, the thickness of the second recessed area 13 should be less than the thickness of the lower rubber backsheet area 11 and the lower burr area 12.
When producing the rubber film, in order to raise the efficiency, can place preceding sole, heel, the corresponding rubber film district of arch of foot in a mould production, however when specifically using, the rubber film district is not whole to paste on the big end, but according to the difference of sole position, selects suitable rubber film laminating, consequently, still need get rid of the deckle edge after the preparation and just can use. The specific preparation process comprises the following steps:
debugging equipment, preparing a formula required for producing the rubber bottom sheet, injecting the formula into a sole mould or preparing the rubber bottom sheet through a mould pressing process, taking out the formula and removing burrs.
Referring to fig. 5, since the upper and lower burr regions 12 of the rubber bottom sheet are connected to each other, when the burrs are removed, the whole burr region can be removed by simply selecting any burr region position of the rubber bottom sheet to tear. Referring to FIG. 6, it can be seen that the edges of the rubber backsheet after the burr and groove areas have been removed are very smooth.
The above description is only an embodiment utilizing the technical content of the present disclosure, and any modification and variation made by those skilled in the art can be covered by the claims of the present disclosure, and not limited to the embodiments disclosed.
