3, the rotary member 300 includes a support 310 having a first rotary hole 311 formed at one side of the lower mold 100 and vertically communicated with the center of the rotary member 300, Shaped bearing portion 320 having a second main hole 321 formed at the center of the first main hole 311 of the first main hole 311 and a second main hole 321 formed at the center of the second main hole 321, And a rotating shaft 330 extending upwardly through the first main shaft 311. The rotating shaft 330 is engaged with the first rotating shaft 311 of the supporting portion 310, The rotation shaft 330 is rotated 360 degrees by the bearing part 320 installed inside the rotation hole 311. That is, the second rotation hole 321 4 and 5, a stepped insertion groove 312 is formed in the inner periphery of the first rotary hole 311 so that the bearing portion 320 is inserted into the first rotary hole 311 The bearing portion 320 is fastened and fixed so that the first and second holes 311 and 321 are communicated with each other while the inner diameter of the first hole 311 is equal to the inner diameter of the second hole 321 I have.

The rotary shaft 330 is then inserted into the first and second holes 311 and 321 so that the rotary shaft 330 is rotated by the bearing portion 320 so that the upper and lower portions of the first and second holes 311 and 321 So that the rotating shaft 330 is moved.

3, a coupling groove 331 is formed at the upper end of the rotation shaft 330 extending to the upper portion of the support portion 310. One end of the coupling shaft 400 is connected to the coupling groove 400, So that the connecting shaft 400 is pivoted to the left and right by the hinge shaft 410.

The other end of the connection shaft 400 is fixed to the one side fixing groove 220 of the upper mold 200 so that the upper mold 200 rotates left and right with respect to the hinge shaft 410.

The upper and lower molds 200 and 100 are integrated with the rotary member 300 and the connection shaft 400 so that the upper and lower molds 200 and 200 can be independently molded and moved .

3 and 4, a rotating shaft 330 (see FIG. 3), which is inwardly inserted into the first main shaft 311 of the supporting portion 310 of the rotating member 300 and is exposed below the first main shaft 311 of the supporting portion 310, And a blocking plate 332 having a larger diameter than the diameter of the first main body 311 is fixed to the end of the shoe sole mold apparatus 10.

A stepped receiving groove 313 is formed in the inner circumferential surface of the first rotary shaft 311 on the lower surface of the support portion 310 to receive the blocking plate 332 of the rotary shaft 330 in the receiving groove 313.

7, the inner surface of the molding hole 110 of the lower mold 100 or the surfaces of the first and second molding protrusions 210a and 210b of the upper mold 200 are formed by the mold member 500, The release member 500 provides a shoe sole manufacturing apparatus comprising a silicone resin, a polyol, and a catalyst containing a polyorganosiloxane and a hydrogensiloxane as a silicone release coating composition.

That is, the mold release member 500 is coated or attached on the entire inner surface of the molding hole 110 of the lower mold 100 or on the entire surfaces of the first and second molding protrusions 210a and 210b of the upper mold 200, The molding fluid injected into the molding hole 110 of the lower mold 100 due to the detachment of the upper mold 200 is compression molded by the first and second molding protrusions 210a and 210b of the upper mold 200, The first and second molding protrusions 210a and 210b of the upper mold 200 are not bonded to the surfaces of the first and second molding protrusions 210a and 210b, (Which is a residue from which the residual molding liquid is ejected in addition to the shape of the molding pores or the first and second molding protrusions of the molded product during compression molding) by the foaming or non-foaming of the molding liquid injected into the mold release member 500 So that there is no need to remove a separate molding fin.

The silicone resin is formed by a crosslinking reaction between a polyorganosiloxane and a hydrogensiloxane. The crosslinking reaction may be crosslinked through any one reaction system selected from the group consisting of a condensation reaction system, an addition reaction system, and an ultraviolet ray or electron beam curing system.

The degree of polymerization of the silicone resin is preferably 50 to 200,000, more preferably 100 to 50,000. When the degree of polymerization is less than 50, the molecular weight of the resin is too low to cause wettability failure that does not cover the entire surface of the substrate during coating. When the molecular weight exceeds 200,000, the molecular weight of the resin is too high, The coating thickness non-uniformity is undesirably caused.

And, the polyorganosiloxane has a low polarity, thereby imparting an antistatic property to the release member, thereby preventing the foreign matter from being mixed and securing the optical safety and peeling uniformity. The polyorganosiloxane preferably has an alkenyl group as a functional group, and the alkenyl functional group may be a vinyl group, a hexenyl group, an acrylic group or a mixed functional group thereof.

The polyorganosiloxane preferably has a weight average molecular weight (Mw) of 10,000 to 1,000,000, more preferably 13,000 to 700,000, and most preferably 15,000 to 600,000. If the weight average molecular weight is less than 10,000, there may arise a problem of coating properties such as poor leveling property to the substrate during coating, and if it exceeds 1,000,000, the viscosity of the coating liquid may increase suddenly at a certain level, The problem of flatness of the coating layer is caused and a difference in the peeling force of the release member is generated.

The hydrogensiloxane serving as a crosslinking agent is a straight-chain poly (methylhydrogen) siloxane having at least two silicon-bonded hydrogen atoms in a molecule and having, for example, a terminal group of trimethylsilyl or hydrogendimethylsilyl; A straight chain type copolymer comprising methylhydrogensiloxane having a terminal group of trimethylsilyl or hydrogendimethylsilyl as a repeating unit; And dimethylsiloxane having a terminal group of trimethylsilyl or hydrogendimethylsilyl as a repeating unit.

The hydrogensiloxane preferably has a weight average molecular weight (Mw) of 800 to 20,000, more preferably 900 to 17,000, and most preferably 1,000 to 15,000. When the weight average molecular weight is less than 800, the crosslinking reaction force is lowered and the mold releasing member 500 is formed on the inner surface of the molding hole 110 of the lower mold 100 or on the surfaces of the first and second molding protrusions 210a and 210b of the upper mold 200, If it exceeds 20,000, the coating layer will remain after the curing reaction, which will affect the deterioration of the peeling force with time.

The hydrogensiloxane may be used in an amount of 0.1 to 10 parts by weight, preferably 0.5 to 7 parts by weight, based on 100 parts by weight of the polyorganosiloxane (based on the solids content). If the content is less than 0.1 part by weight, it is difficult to form a coating layer of the first and second molding protrusions because the Si-H group bridging with the alkenyl group of the polyorganosiloxane is insufficient and the reaction can not be performed. When the content is more than 10 parts by weight, The residual amount of the excess amount of the catalyst becomes low, and the stability of the peeling force with time is lowered, so that the peeling force of the releasing member may be increased.

The polyol improves the cohesive force between the polyorganosiloxane and the hydrogensiloxane, which is a crosslinking agent, to maintain the adhesive force even in a harsh state, and to improve adhesion with a substrate. When the polyol has two or more hydroxyl groups in one molecule, It does not.

As the polyol, for example, at least one selected from the group consisting of a polyacryl polyol, a polyether polyol, a polyester polyol, a polycarbonate polyol and a polycaprolactone polyol can be used.

As the polyacrylic polyol, an acrylic copolymer in which (meth) acrylic acid ester alone or a copolymerized monomer having a (meth) acrylic acid ester and a hydroxyl group is copolymerized can be used. Examples of the copolymerizable monomer having a hydroxyl group include? -Hydroxyethyl acrylate,? -Hydroxypropyl acrylate, 3-hydroxypropyl acrylate,? -Hydroxybutyl acrylate, 4-hydroxybutyl acrylate and? -Hydroxypentyl acrylate Hydroxyalkyl esters of acrylic acid or methacrylic acid and the like; A polyol such as a monoester of acrylic acid or a methacrylic acid monoester of polyhydric alcohol, N-methylol acrylamide, N-methylol methacrylamide, or a copolymer thereof of polyhydric alcohol such as glycerin and trimethylolpropane may be used.

The polyether polyol may be a copolymer of polyethylene glycol, 1,2-polypropylene glycol, polytetramethylene glycol, 1,2-polybutylene glycol, or the like with each polyol; Examples of the polyester polyol include ethylene glycol, polyethylene glycol, propylene glycol, polypropylene glycol, polytetramethylene glycol, 1,3-butanediol, 1,4-butanediol, 1,5-pentanediol, 1,6- Isophthalic acid, terephthalic acid, maleic acid, fumaric acid, adipic acid, sebacic acid, sebacic acid, isophthalic acid, isophthalic acid, A polyester polyol in the form of an acid such as azelic acid or a copolymer thereof may be used. As the polycarbonate polyol, 1,6-hexane polycarbonate can be used. As the polycaprolactone polyol,? -Caprolactone and ethylene glycol, polyethylene glycol, propylene glycol, polypropylene glycol, 1,3-butanediol, 4-butanediol, polytetramethylene glycol, 1,2-polybutylene glycol, 1,6-hexanediol, neopentyl glycol and 1,4-cyclohexanedimethanol may be used.

The polyol preferably has a weight average molecular weight (Mw) of 200 to 4000. If the weight average molecular weight is less than 200, the rigidity is high and the rigidity and physical properties may be weak. When the weight average molecular weight is more than 4000, the rigidity is low and the physical properties such as strength as the fixing material are low.

The polyol may be appropriately mixed with additives such as polypropylene glycol (PPG), bisphenol-based diol (BP, BPE) or a mixture thereof in order to maintain proper physical properties for adhesion to the substrate. At this time,

0.1 to 10 parts by weight based on 100 parts by weight of the total weight of the composition.

The amount of the polyol is preferably 0.1 to 10 parts by weight, more preferably 0.5 to 5 parts by weight based on 100 parts by weight of the silicone resin. If the amount is less than 0.1 part by weight, there is a problem that adhesion with a base material is lowered. If the amount is more than 10 parts by weight, excessive OH groups may remain, resulting in deterioration in stability over time and a problem that the releasing force of the releasing member is increased.

The catalyst may be a platinum compound as a crosslinking accelerator for accelerating a crosslinking reaction between a polyorganosiloxane and a hydrogensiloxane.

As the platinum-based compound, for example, platinum in the form of fine particles, platinum in the form of fine particles adsorbed on a carbon powder carrier, chloroplatinic acid, alcohol-modified chloroplatinic acid, olefin complex of chloroplatinic acid, palladium and rhodium can be used.

The catalyst is preferably contained in an amount of 0.01 to 0.1 part by weight, more preferably 0.02 to 0.08 part by weight based on 100 parts by weight of the silicone resin. If the content is less than 0.01 part by weight, the silicone release agent tends to be contaminated with the pressure-sensitive adhesive due to uncured cured product, resulting in deterioration of adhesion. If the content exceeds 0.1 parts by weight,

The silicone release coating liquid is prepared so that the concentration of the total solid content is 0.5 to 10% by weight. If the concentration is less than 0.5% by weight, coating failure resulting in insufficient presence of silicone resin on the surface of the substrate after coating drying occurs. If the concentration is more than 10% by weight, the viscosity of the coating solution increases sharply, .

The silicone release coating liquid is applied in an amount of 0.05 to 2.0 g / m 2, more preferably 0.07 to 1.5 g / m 2, and the thickness of the coating layer is adjusted to 5 to 150 nm after drying.

A release film is adhered to the inner surface of the lower mold 100 molding hole 110 or the surfaces of the first and second molding protrusions 210a and 210b of the upper mold 200 to separate the release member 500 And a release film is prepared using the silicone release coating liquid composition. Specifically, the release film may be formed by applying the silicone release coating composition on one surface of a base film, heating, drying and curing the release film to form a release film on the inner surface of the molding hole 110 of the lower mold 100, 1, 2 forming protrusions 210a, 210b.

The base film may be a film excellent in transparency, mechanical strength, thermal stability, moisture barrier properties, isotropy, and the like.
