The airflow is used to blow away the debris at the connection between the active cavity and the molding cavity to prevent the debris from entering the active cavity. The flowing airflow can also push the sole upward, making it easier to take the sole. BRIEF DESCRIPTION OF THE DRAWINGS

The through slot 311 is located on the side outer wall of the lower mold body 1, and the through slot 311 is communicated with the placement cavity 5. The top plate 313 is slidably arranged in the placement cavity 5, and the top of the top plate 313 is fixedly connected to the bottom end of the top rod 8. A connecting plate 312 is fixedly installed on the side outer wall of the top plate 313, and the connecting plate 312 is slidably arranged in the through slot 311. A guide rail 314 is fixedly installed on the top of the connecting plate 312. A T-slot 315 is provided on the outer wall of the guide rail 314, and the height of the T-slot 315 is greater than the height of the L-shaped rod 317. A T-block 316 is slidably arranged on the inner wall of the T-slot 315. The T-block 316 is fixedly installed on the inner wall of the T-slot 315. The outer wall of the upper mold body 16 is fixedly connected to the bottom end of the L-shaped rod 317, and the top end of the L-shaped rod 317 is fixedly installed on the side outer wall of the upper mold body 2. A T-shaped block 316, a T-shaped slot 315, and a guide rail 314 are provided to connect the connecting plate 312 and the L-shaped rod 317. The upper mold body 2 is raised to drive the L-shaped rod 317 to rise, and then drive the connecting plate 312 to rise, so that the connecting plate 312 drives the top plate 313 to rise to push the top rod 8 upward, and then push the high temperature resistant sealing plug 6 upward, so that the high temperature resistant sealing plug 6 pushes out the sole formed in the lower mold body 1, and because the T-shaped block 316 can slide relative to the guide rail 314, when the L-shaped rod 317 drives the T-shaped block 313 to push the top rod 8 upward, the high temperature resistant sealing plug 6 is pushed out. When the shoe sole is lifted up, only when the T-block 316 moves to the top of the T-slot 315 can the T-block 316 drive the guide rail 314 to rise, thereby preventing the high temperature resistant sealing plug 6 from moving up to push out the shoe sole when the lower mold body 1 and the upper mold body 2 are not completely separated. The rebound portion 32 includes a spring 321 and a pressing plate 322. The spring 321 is fixedly mounted on the top of the top plate 313.

The spring 321 is provided to push the top plate 313 downward, that is, when the upper mold body 2 gradually moves downward, the spring 321 pushes The top plate 313 moves downward so that the top plate 313 drives the top rod 8 and the high temperature resistant sealing plug 6 to move downward and reset, and the high temperature resistant sealing plug 6 is reset before the lower mold body 1 and the upper mold body 2 are not closed, to ensure that the injected glue liquid will not enter the active cavity 4 when the glue is injected into the lower mold body 1, and a pressing plate 322 is provided to press on the top of the guide rail 314 after the lower mold body 1 and the upper mold body 2 are completely closed, so that the guide rail 314 cannot move up, and then the connecting plate 312, the top plate 313, the top rod 8, and the high temperature resistant sealing plug 6 are limited, so that the high temperature resistant sealing plug 6 cannot move up, to avoid external vibration during the molding of the glue liquid causing the high temperature resistant sealing plug 6 to move up and enter the molding cavity in the lower mold body 1.

[0036] Furthermore, two through slots 311 and connecting plates 312 are provided and are symmetrically distributed about the top plate 313 , so that the top plate 313 can be driven to move up and down from both left and right ends at the same time, making the top plate 313 move up and down more smoothly.

[0037] Example 2

[0038] On the basis of Example 1, a preferred embodiment of a glue injection mold for sole production provided by the utility model is as follows Figures 1 to 4 As shown, the blowing part 33 includes an L-shaped plate 331, which is fixedly mounted on the side outer wall of the guide rail 314, an air bag 333 is fixedly mounted on the top inner wall of the L-shaped plate 331, and an extrusion plate 334 is fixedly mounted on the bottom of the air bag 333. A slide groove 335 is provided on the side outer wall of the L-shaped plate 331, and a slider 338 is slidably provided on the inner wall of the slide groove 335. The outer wall of the slider 338 is fixedly connected to the outer wall of the extrusion plate 334, and the slider 338 extends into the T-shaped slot 315, and the slider 338 is fixedly connected to the outer wall of the T-shaped block 316. The bottom of the airbag 333 is connected with a one-way valve 337, and the bottom of the one-way valve 337 is connected with a hose 336. The end of the hose 336 away from the one-way valve 337 passes through the outer wall of the limit ring 7 and extends to the top of the limit ring 7. The top of the airbag 333 is connected with a one-way valve 332. The one-way valve 332 can only exhaust air from one end connected to the airbag 333 and inlet air from the other end. The one-way valve 337 can only inlet air from one end connected to the airbag 333 and exhaust air from the other end. A one-way valve 336 is provided on the airbag 333. The first valve 332 and the second one-way valve 337 make the air inlet and outlet channels of the airbag 333 fixed, that is, when the airbag 333 is squeezed, the air inside it can only be discharged by opening the second one-way valve 337. A slider 338 is provided to connect the squeezing plate 334 and the T-block 316 so that the T-block 316 moves upward to drive the squeezing plate 334 to move upward to squeeze the airbag 333. After the T-block 316 contacts the inner wall of the top end of the T-slot 315, the T-block 316 drives the guide rail 314 to rise, thereby driving the L-shaped plate 331 to rise, so that The airbag 333 and the extrusion plate 334 rise synchronously, that is, the airbag 333 is no longer squeezed, and after the one-way valve 337 is opened, the gas in the airbag 333 is blown from the hose 336 to the bottom of the high temperature resistant sealing plug 6, and at this time, the high temperature resistant sealing plug 6 rises to lift the sole, and the airflow enters the molding cavity along the gap between the sole and the molding cavity in the lower mold body 1, and the airflow is used to blow away the debris at the connection between the active cavity 4 and the molding cavity, so as to prevent the debris from entering the active cavity 4, and the flowing airflow can also push the sole upward, making it easier to take the sole;

[0039] Two L-shaped plates 331 are provided and are respectively located on the outer walls of the left and right guide rails 314, for arranging two airbags 333 to increase the blowing volume. The airbags 333 are made of rubber, so that the airbags 333 can withstand a larger range of extrusion and stretching, and when there is no external force, the air in the airbags 333 can also be blown out when the main body of the airbags 333 contracts. The hose 336 passes through the T-slot 315 to prevent the hose 336 from extending into the bottom of the connecting plate 312, causing the hose 336 to be squeezed when the connecting plate 312 is reset.

[0040] When the utility model is in use, the molding cavity in the lower mold body 1 is injected with glue injection glue, and then the lower mold body 1 and the upper mold body 2 are closed to form. After the molding is completed, the upper mold body 2 is opened to make the upper mold body 2 move up, and the upper mold body 2 moves up to drive the L-shaped rod 317 to move up, and then drives the T-shaped block 316 to move up. When the T-shaped block 316 moves up to the top of the T-shaped groove 315, the T-shaped block 316 moves up to drive the guide rail 314 to move up, and then drives the connecting plate 312 and the top plate 313 to move up. The top plate 313 moves up to push the top rod 8 and the high temperature resistant sealing plug 6 to move up, so that the high temperature resistant sealing plug 6 is removed from the movable cavity 4. The upper mold body 2 extends outward to push out the sole in the molding cavity. After taking out the sole, the upper mold body 2 is opened to move the upper mold body 2 downward. The downward movement of the upper mold body 2 drives the L-shaped rod 317 to move downward, and then drives the T-shaped block 316 to move downward, so that the T-shaped block 316 no longer pushes up the guide rail 314. At this time, the spring 321 pushes the top plate 313 to move downward, and then drives the push rod 8 and the high temperature resistant sealing plug 6 to move downward, so that the high temperature resistant sealing plug 6 is reset. The high temperature resistant sealing plug 6 is reset before the lower mold body 1 and the upper mold body 2 are closed, and then the above steps can be repeated to continuously use the lower mold body 1 and the upper mold body 2 to perform injection molding on the sole.
