DETAILED DESCRIPTION

[0024] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. The same parts are represented by the same reference numerals. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the accompanying drawings, and the words "bottom surface" and "top surface", "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0025] Reference Figures 1 to 6As shown, an automatic lasting machine of the present embodiment comprises a rotating body 1 and a plurality of shoe mold fixing assemblies 2 arranged on the side of the rotating body 1, wherein the shoe mold fixing assemblies 2 are arranged in a circular array with the center of the rotating body 1 as the axis, a support base 11 for supporting the rotating body 1 is arranged below the rotating body 1, a mold changing assembly 4, a driving assembly 5 and an injection molding device 6 which are opposite to the shoe mold fixing assembly 2 are arranged on the supporting base 11, the driving assembly 5 is linked with the shoe mold fixing assembly 2, and the driving assembly 5 is used to drive the shoe mold fixing assembly 2 to rotate, and the shoe mold fixing assembly 2 comprises a mounting plate 21, a shoe mold 22 and a retaining plate 23, a A pulling mechanism 3 is connected to the shoe mold fixing assembly 2, and a fixing bracket 211 is arranged on the mounting plate 21. One end of the fixing bracket 211 is connected to the rotating body 1, and the other end is fixedly connected to the mounting plate 21. The shoe mold 22 is fixed on the mounting plate 21, and a toe cap 221 is arranged inside the shoe mold 22. The retaining plate 23 is fixed to one end of the toe cap 221 away from the shoe mold 22, and an injection port 222 is arranged on the toe cap 221. The pulling mechanism 3 includes a pulling member 31 and a driver 32. The driver 32 is linked to the pulling member 31. When the driver 32 is turned on, the pulling member 31 can pull out the waste material in the injection port 222.

[0026] The above-mentioned improvements are specifically as follows: the injection molding machine injects the raw materials for making the soles into the interior of the shoe mold 22, and transmits them to the position corresponding to the pulling mechanism 3 through the turntable. The pulling mechanism 3 includes a pulling piece 31 and a driver 32. Through the action of the driver 32, the pulling piece 31 can be effectively driven to pull out the waste material outside the shoe mold 22. After the waste material is pulled out, the shoe mold fixing component 2 rotates to the mold changing position corresponding to the mold changing component 4 to change the mold (replace the completed injection molded one, and then replace the main injection molded shoe last) to start a new cycle.

[0027] On the basis of the above embodiment, the pulling member 31 includes a left pressure nozzle 311 and a right pressure nozzle 312, the left pressure nozzle 311 and the right pressure nozzle 312 can be separated, the left pressure nozzle 311 is provided with a left protrusion 313, the right pressure nozzle 312 is provided with a right protrusion 314, the left protrusion 313 and the right protrusion 314 are surrounded to form a fixed block 315 for inserting into the injection port 222, the left pressure nozzle 311 and the right pressure nozzle 312 are provided with a guide rail 316, the driver 32 is a cylinder, the The guide rail 316 is connected to the cylinder, and a connecting rod 317 is provided on the left pressure nozzle 311 and the right pressure nozzle 312. Both ends of the connecting rod 317 are connected to the guide rail 316. The guide rail 316 can move outward. The length of the left pressure nozzle 311 is shorter than that of the right pressure nozzle 312. A stripping stop frame 33 is fixed to the lower side of the mounting plate 21, and a stripping stop rod 34 is provided on the stripping stop frame 33. When the right pressure nozzle 312 conflicts with the stripping stop rod 34, the left pressure nozzle 311 can be separated from the right pressure nozzle 312.

[0028] The above-mentioned improvement is specifically as follows: when the pulling piece 31 is not subjected to external force, the fixed block 315 formed by the left protrusion 313 and the right protrusion 314 conflicts with the injection port 222. After the injection molding in the shoe mold 22 is completed, the cylinder drives the guide rail 316 to move outward. At this time, the fixed block 315 formed by the left protrusion 313 and the right protrusion 314 will bring out the waste in the injection port 222. At this time, the left pressure nozzle 311 and the right pressure nozzle 312 can be separated. The waste originally clamped by the left pressure nozzle 311 and the right pressure nozzle 312 will fall directly after being brought out (a connecting spring is arranged between the left pressure nozzle 311 and the right pressure nozzle 312. Therefore, after the left pressure nozzle 311 and the right pressure nozzle 312 are separated, due to the elastic potential energy of the spring, they can return to their original position). The entire working process can achieve the effect of direct falling of the waste in the injection port 222 during operation.
