DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0021] Please refer to Figures 1-3 A shoe sole shaping device with anti-overflow edge for rubber sole production, which comprises a shaping table 1 convenient for operators to operate, and the shaping table 1 is fixedly connected with a lower support 2 at the bottom, and the shaping table 1 is supported to a proper height through the lower support 2, so that the user can use it more conveniently.

[0022] The upper support 3 is fixedly connected with the shaping table 1 at the top and has the functions of supporting and connecting, and the upper sliding plate 5 is slidably connected in the inner cavity of the upper support 3, and the driving device for driving the upper sliding plate 5 to move is installed at the top of the upper support 3, so that the upper sliding plate 5 can be driven to move vertically in the inner cavity of the upper support 3 by the driving device when the user starts the driving device, and the position of the upper sliding plate 5 can be adjusted.

[0023] Two annular cutters 8 are symmetrically installed on the lower surface of the upper sliding plate 5, the shaping plate 9 is fixedly connected in the annular cutters 8 through elastic structures, and the bottom height of the shaping plate 9 is lower than the bottom height of the annular cutters 8.

[0024] The lower die groove 13 opposite to the shaping plate 9 is formed in the shaping table 1 below the shaping plate 9, the cutting edge of the annular cutter 8 and the shaping table 1 on the side of the lower die groove 13 are located on the same vertical plane, and the electric heating wire 15 electrically connected with the external power supply is embedded in the side wall of the lower die groove 13. The rubber sheet in the inner cavity of the lower die groove 13 is heated through the electric heating wire 15, so that the rubber sheet is deformed by heating, then the shaping plate 9 is driven to move downward to the inner part of the lower die groove 13 by the driving device to extrude the heated rubber sheet, so that the rubber sheet is deformed, and the rubber sole can be formed after the rubber sheet is solidified.

[0025] Specifically, please refer to Figure 1The driving device comprises a screw rod 6 penetrating through the middle section of the upper slide plate 5 and being screwed with the upper slide plate 5, a motor 7 fixedly connected to the upper support 3 above the screw rod 6, and the output end of the motor 7 fixedly connected with the top end of the screw rod 6 after penetrating through the upper support 3. Since the upper slide plate 5 is screwed with the screw rod 6, when the motor 7 is started, the motor 7 drives the screw rod 6 to rotate, which can push the upper slide plate 5 to move up and down along the height direction of the screw rod 6 under the action of the screw thread, so as to move the upper slide plate 5 to the appropriate position.

[0026] Specifically, please refer to Figure 1 and Figure 2 The size of the shaping plate 9 is adapted to the size of the inner cavity of the annular cutter 8 and the lower mold groove 13, the elastic structure comprises a sliding rod 11 fixedly connected to the upper surface of the shaping plate 9 and a sliding pipe 10 fixedly connected to the inner wall of the annular cutter 8, a spring 12 is fixedly connected in the inner cavity of the sliding pipe 10, and a section of the sliding rod 11 away from the shaping plate 9 is arranged in the inner cavity of the sliding pipe 10 and fixedly connected with the spring 12. Since the bottom height of the shaping plate 9 is lower than the bottom height of the annular cutter 8, when the annular cutter 8 is driven downward by the upper slide plate 5, the shaping plate 9 first contacts the rubber sheet after heat treatment and extrudes the rubber sheet to shape the rubber sheet. After shaping, the annular cutter 8 is continuously pressed downward, the sliding rod 11 slides to the inside of the sliding pipe 10, the spring 12 is extruded and shrinks, and the annular cutter 8 is attached to the shaping table 1 on the side of the lower mold groove 13, so that the excess rubber overflowed on the shaping table 1 is cut off.

[0027] Specifically, please refer to Figure 1 The inner cavity of the lower mold groove 13 is embedded with a top plate 14, the top plate 14 is slidably connected with the inner wall of the lower mold groove 13, and a through hole 16 is formed in the bottom wall of the inner cavity of the lower mold groove 13 and communicates with the inside of the lower mold groove 13. After the rubber sole is shaped, the top plate 14 can be pushed to slide along the height direction of the lower mold groove 13 by a jacking mechanism arranged through the through hole 16, so that the rubber sole in the inside of the lower mold groove 13 is pushed out, which is convenient for workers to unload.

[0028] Specifically, please refer to Figure 1 and Figure 3 A lower slide plate 17 is sleeved with a section of the screw rod 6 below the shaping table 1, the lower slide plate 17 is screwed with the screw rod 6, and two top rods 18 corresponding to the through hole 16 are fixedly connected to the upper surface of the lower slide plate 17. When the screw rod 6 rotates to drive the upper slide plate 5 to move upward, the lower slide plate 17 can also be driven to move upward synchronously by the same principle, so that the two top rods 18 penetrate through the through hole 16 and extrude the top plate 14 upward, so that the shaped rubber sole is pushed out.

[0029] Specifically, please refer to Figure 1The limiting sliding groove 4 is arranged on the inner side wall of the upper support 3 and the lower support 2, and the two ends of the upper sliding plate 5 and the lower sliding plate 17 are slidably connected with the upper support 3 and the lower support 2 through the limiting sliding groove 4. The limiting sliding groove 4 is arranged for limiting and guiding the upper sliding plate 5 and the lower sliding plate 17, so as to avoid the problem that the upper sliding plate 5 and the lower sliding plate 17 rotate synchronously with the screw rod 6 when the screw rod 6 rotates, and the positions of the upper sliding plate 5 and the lower sliding plate 17 cannot be adjusted.

[0030] Specifically, the maximum compression length of the spring 12 is not less than the vertical distance between the bottom of the annular cutter 8 and the lower surface of the shaping plate 9. The problem that the spring 12 is excessively pressed and damaged when the annular cutter 8 cuts the excess edge of the rubber sole is avoided.

[0031] Working principle: when in use, the user places the rubber sheet into the inner cavity of the lower mold groove 13 arranged on the shaping table 1, then connects the electric heating wire 15 with the external power supply, and heats the rubber sheet through the electric heating wire 15. Meanwhile, the user starts the motor 7 to drive the screw rod 6 to rotate, and the upper sliding plate 5 is driven to move downward along the height direction of the screw rod 6 under the action of the screw thread, so as to drive the annular cutter 8 installed on the lower surface of the upper sliding plate 5 to move downward. Since the bottom of the shaping plate 9 is lower than the bottom of the annular cutter 8, the shaping plate 9 is first contacted with the rubber sheet after heat treatment during the downward movement, and the rubber sheet is pressed to shape the rubber sheet. After shaping, the annular cutter 8 is continuously pressed downward, the sliding rod 11 is slid to the inside of the sliding pipe 10, the spring 12 is contracted, and the annular cutter 8 is attached to the shaping table 1 on the side of the lower mold groove 13, so as to cut the excess rubber edge overflowing on the shaping table 1. The problem that the rubber material in the mold of the existing sole shaping device is easy to overflow during the working process, and the staff needs to trim the overflow, greatly increasing the working complexity, is avoided.

[0032] In addition, it should be noted that, in the description of the present application, unless otherwise specified and limited, the terms "mounting", "connecting", "connecting" should be understood in a broad sense, for example, it can be fixed connection, or detachable connection, or integrally connected, it can be mechanical connection, or electrical connection, it can be directly connected, or indirectly connected through an intermediate medium, or the communication between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0033] The above are the preferred embodiments of the present application, which do not limit the protection scope of the present application, therefore: any equivalent changes made on the structure, shape and principle of the present application should be covered within the protection scope of the present application.
