Detailed Implementation

[0026] Example 1

[0027] like Figures 1-4As shown, this utility model proposes a mold for producing rubber new material shoe soles, including a base 1, a drive assembly A, a movable plate 4, a pushing assembly 7, a bracket 8, a discharge hopper 13, and a transmission assembly. The base 1 includes four workstations: a loading station, a forming station, a backup station, and a unloading station. A turntable 2 is rotatably connected to the base 1. Several sets of mold grooves 201 are arranged in a circular array around the axis on the upper surface of the turntable 2, and an annular groove 202 with its opening facing downwards and coaxial with it is also provided on the turntable 2. The drive assembly A includes, but is not limited to, a motor 3. The motor 3 is a servo motor, and its body is mounted on the base 1. The output end of the motor 3 is connected to the central axis of the turntable 2, and the motor 3 drives the turntable 2 to rotate intermittently. While rotating, the turntable 2 rotates the mold groove 201 at the loading station to the forming station, rotates the mold groove 201 at the forming station to the alternative station, rotates the mold groove 201 at the alternative station to the unloading station, and rotates the mold groove 201 at the unloading station back to the loading station. Several movable plates 4 are arranged in a circular array around the axis of the turntable 2 within the annular groove 202. The movable plates 4 slide along the axial direction of the turntable 2. Several push rods 5 are mounted on the movable plates 4, each push rod 5 inserting into the corresponding mold groove 201. A sealing block is mounted at the top of each push rod 5, and a sealing groove adapted to the sealing block is mounted on the bottom surface of the mold groove 201. When the movable plate 4 is in a low position, the upper surface of the sealing block is flush with the bottom surface of the mold groove 201; when the movable plate 4 is in a high position, the upper surface of the sealing block is not lower than the upper surface of the turntable 2. The push assembly 7 is mounted on the base 1 and includes a fixed seat 71, a rotating shaft 72, a baffle 73, and rollers 74. The fixed seat 71 is connected to the upper surface of the base 1, the rotating shaft 72 is rotatably connected to the fixed seat 71, the movable plate 4 is located above the fixed seat 71 and the rotating shaft 72, four baffles 73 are arranged in a circular array on the rotating shaft 72, and the rollers 74 are rotatably connected to the end of the baffles 73 away from the rotating shaft 72. In operation, the push assembly 7 pushes the movable plate 4, which has rotated to its upper position, upward to eject the formed shoe sole. A horizontal plate 9 is movably mounted on the support 8, a sealing plate 11 is mounted at the bottom of the horizontal plate 9, and a punch 12 adapted to the mold groove 201 directly below the sealing plate 11 is mounted at the bottom of the sealing plate 11. A drive assembly B for driving the horizontal plate 9 to rise and fall is mounted on the support 8. The drive assembly B includes, but is not limited to, a hydraulic cylinder 10. The body of the hydraulic cylinder 10 is connected to the bracket 8, and the output end of the hydraulic cylinder 10 is connected to the horizontal plate 9. Several guide rods are provided on the horizontal plate 9, and the guide rods are slidably connected to the bracket 8. The hydraulic cylinder 10 is connected to an external hydraulic pump. The discharge hopper 13 is set on the bracket 8 and has a clearance fit with the upper end face of the turntable 2. A push plate 14 is slidably set on the inner wall of the discharge hopper 13. The punch 12 is located above the forming station, the push assembly is located at the unloading station, and the discharge hopper 13 is located at the unloading station.The transmission assembly includes a connecting rod 15, the two ends of which are rotatably connected to the horizontal plate 9 and the push plate 14 respectively. The transmission assembly drives the horizontal plate 9 and the push plate 14 so that when the horizontal plate 9 is in a downward state, the push plate 14 pushes the shoe sole that is pushed into the discharge hopper 13 by the push assembly 7 to slide out of the discharge hopper 13.

[0028] In this embodiment, firstly, a measured amount of raw material is added to the mold trough 201 at the loading station, and the raw material is appropriately and evenly distributed. Then, the motor 3 drives the turntable 2 to rotate 90 degrees, and the mold trough 201 with the raw material rotates to the forming station. The hydraulic cylinder 10 pushes down the horizontal plate 9, the sealing plate 11, and the punch 12. The punch presses into the mold trough 201 below it and presses the raw material into shape, forming a shoe insole blank. The motor 3 continues to drive the turntable 2 to rotate 90 degrees, and the blank rotates to the alternative station. The next mold trough with raw material rotates to the forming station. As the motor 3 drives the turntable 2 to continue rotating 90 degrees, when the mold trough 201 at the alternative station rotates to the unloading station, the front end of the movable plate 4 at the bottom of the mold trough 201 abuts against the upward (or inclined upward) baffle 73. Since the included angle between two adjacent baffles 73 is 90 degrees, The movable plate 4 continues to rotate, and its front end pushes the currently contacted baffle 73 to rotate, thereby causing the next baffle 73 to rotate as well and lift the movable plate 4 upward. When the mold groove 201 just rotates to the unloading station, the movable plate 4 corresponding to the unloading station is lifted upward, and at the same time, the ejector rod 5 pushes the molded shoe sole in the mold cavity 201 upward until the shoe sole leaves the mold groove 201 and enters the discharge hopper 13. Then, when the punch 12 descends again, the horizontal plate 9 descends and pushes the push plate 14 to slide through the connecting rod 15. Then, the sliding push plate 14 pushes the shoe sole that has entered the discharge hopper 13 out of the outlet of the discharge hopper 13, realizing automatic unloading without manual intervention and with high safety. The punch 10 rises and resets, and then drives the push plate 14 to slide back and reset through the connecting rod 15, which facilitates the pushing of the next shoe sole.

[0029] Example 2

[0030] like Figure 2 As shown, the mold for producing rubber new material shoe soles proposed in this utility model, compared with Embodiment 1, has a spring 6 sleeved on the top rod 5, and the two ends of the spring 6 abut against the upper wall of the annular groove 202 and the upper end surface of the movable plate 4, respectively.

[0031] In this embodiment, by setting spring 6, the movable plate 4 can quickly slide down and reset after disengaging from baffle 173 and roller 174. Furthermore, by utilizing the tension of spring 6, the sealing block at the top of the push rod 5 can quickly fall back into the sealing groove and maintain a rapid fit with the sealing groove, thereby preventing the risk of raw materials getting stuck in the sealing groove during the feeding process due to delayed fall of the push rod 5.

[0032] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
