As shown in fig. 1-4, a sole casting mold convenient for demolding comprises an upper mold 1, a lower mold 2 and a cooling pool 3 for cooling soles, wherein the upper mold 1 covers the lower mold 2, the upper mold 1 is driven to lift through a hydraulic oil cylinder 11, and the upper mold 1 is provided with a communication port 12 communicated with an injection molding pipe; the side of the cooling pool 3 is respectively communicated with a water inlet pipe and a water outlet pipe, the connecting end of the water outlet pipe and the cooling pool 3 is arranged close to the inner lower end face of the cooling pool 3, when in use, the connecting end is connected with a plastic solution filling end through a communicating port 12, the solution is injected into a lower die 2 through the communicating port 12, an upper die 1 is driven by a hydraulic oil cylinder 11 to press the lower die 2 downwards to form a shoe sole, the shoe sole is different from the prior art, the lower die 2 in the invention is separable, the cooling pool 3 is filled with water for cooling, the shoe sole can directly fall into the cooling pool 3 to be cooled by the water after being demoulded, so that an operator does not need to demould the shoe sole by hands, and the distinguishing technology is further introduced as follows:

in this embodiment, the lower mold 2 is composed of a first single mold 21 and a second single mold 22, the surfaces of the first single mold 21 and the second single mold 22 are respectively provided with a concave layer, the concave layer of the first single mold 21 and the concave layer of the second single mold 22 form a concave mold for forming a sole, and the communication port 12 on the upper mold 1 is communicated with the concave mold to inject a plastic solution into the concave mold, while the first single mold 21 and the second single mold 22 are separated from the central axis of the lower mold 2, and both ends of the concave mold of the lower mold 2 are not bent inward, and the formed sole can be pulled when the first single mold 21 is separated from the second single mold 22, and the sole is not affected by the blockage and the pulling of the concave mold, and it needs to be explained that, when the first single mold 21 is separated from the second single mold 22, the space width between the two is greater than the width of the sole, so that the sole can be effectively dropped into the cooling pool 3.

Further, two sides of the lower die 2 are respectively provided with a fixing plate 23, a plurality of sliding grooves 231 are respectively symmetrically arranged between adjacent surfaces of the two fixing plates 23, and two sides of the first single die 21 and the second single die 22 are respectively embedded into the sliding grooves 231 through a rotating shaft; the symmetrically arranged sliding grooves 231 are gradually far away from each other from top to bottom so as to separate the first single mode 21 and the second single mode 22 when moving from top to bottom, so that the sole is demolded, the fixing plate 23 is arranged to be used for fixing and guiding, more of the purposes are that the lower die 2 is limited, and the two ends of the first single mode 21 and the second single mode 22 are tightly abutted against the fixing plate 23, so that the female die formed by the first single mode 21 and the second single mode 22 can be spliced into a tight joint, a sheet layer on the surface of a finished sole is reduced, and leakage of a plastic solution is avoided; when first single mode 21 and second single mode 22 offset and constitute lower mould 2, the lower terminal surface of limiting plate 234 offsets with the lower mould 2 up end, thereby the setting can make first single mode 21 and second single mode 22 can directly not remove to both sides when gliding thereby striking limiting plate 234.

Furthermore, in order to control the up-down lifting and the separation combination function of the lower die 2, the front side and the rear side of the lower end of the first single die 21 and the lower end of the second single die 22 are respectively driven to lift through a cylinder 24, each cylinder 24 is rotatably connected to the inner side of the fixing plate 23 through a rotating clamping piece 241, the output shaft of each cylinder 24 is connected with the corresponding first single die 21 and the corresponding second single die 22 through a universal shaft, the cylinder 24 can also be provided with a mechanism which has an output shaft and can extend outwards, such as a hydraulic oil cylinder, an electric push rod, a telescopic rod and the like, and a waterproof layer is sprayed on the outer side of the cylinder 24, so that water cannot permeate into the cylinder 24 when the cylinder 24 is placed in water.

Furthermore, each side of the fixing plate 23 has a plurality of wedge ports 232, a reinforcing member 233 is clamped in each wedge port 232, the reinforcing member 233 is inserted into the wedge port 232 from outside to inside and abuts against the lower mold 2, so that the reinforcing member 233 can be inserted when the first single mold 21 and the second single mold 22 are gathered together to form the lower mold 2, the upper end of the lower mold 2 abuts against the limiting plate 234 to form a limit position, the lower end of the lower mold 2 is abutted against the reinforcing member 233 to limit, and the problem that the lower mold 2 displaces due to internal pressure reinforcement when plastic is injected is avoided.

In order to form continuous interference fixation on the lower die 2 through the reinforcement 233, in this embodiment, the lower end horizontal plane of the lower die 2 is located between the inner upper and lower end horizontal planes of the wedge 232, and the upper end of the reinforcement 233 is inclined downward toward one side of the lower die 2, so that the reinforcement 233 penetrates through the wedge 232 and then abuts against the lower end of the lower die 2 through the inclined surface of the reinforcement 233, and thus the reinforcement 233 can be inserted into the wedge 232 more conveniently and penetrate below the lower die 2, and meanwhile, in order to improve fixation of the lower die 2, the embedded length of the reinforcement 233 can be increased, and the inclined surface of the reinforcement 233 is used to extrude the lower end of the lower die 2 to form wedge connection.

In addition, the cross-sectional profile of the wedge 232 is matched with that of the reinforcing member 233, so that the stability of the reinforcing member 233 after being fixed can be effectively improved.

Further, two be equipped with a stripping part 235 between the adjacent face of fixed plate 23 respectively, two stripping parts 235 all are located the center between first monomode 21 and the second monomode 22, so set up and to let first monomode 21, second monomode 22 separate the back that moves down, let the fashioned sole be separated by stripping part 235 jack-up and the die surface of lower mould 2, and stripping part 235 is close to lower mould 2 setting, can let first monomode 21 and second monomode 22 move down and to let stripping part 235 insert in first monomode 21 after a distance in the time of separating gradually, let stripping part 235 butt fashioned sole gradually, until the sole is along with the separation of first monomode 21 with second monomode 22 and the butt of stripping part 235 after being peeled off the die surface, finally fall into cooling tank 3, by the water cooling in cooling tank 3, so that operating personnel picks up the sole after the cooling.

In order to enable the stripping member 235 to be more conveniently inserted between the first single mold 21 and the second single mold 22, in this embodiment, the lower end edges of the adjacent surfaces of the first single mold 21 and the second single mold 22 are respectively provided with an inclined surface, the inclined surface of the first single mold 21 and the inclined surface of the second single mold 22 form a flaring-shaped structure, one end with a larger caliber faces downwards, the two stripping members 235 are both in a tapered structure with a small top and a large bottom, and the center line of the stripping member 235 is perpendicular to the center line of the flaring-shaped structure.
