DETAILED DESCRIPTION

[0023] The utility model is now further described in conjunction with the accompanying drawings and specific implementation methods.

[0024] refer to Figures 1 to 6 This embodiment provides a shearing device for shearing multiple nozzles at one time, comprising a support platform 1, a positioning station 2 provided on the support platform 1 and used for positioning the injection molded part, a fixing station 3 used for fixing the injection molded part, and a shearing machine 4 used for shearing multiple nozzles of the injection molded part.

[0025] The shearing machine 4 includes a displacement block 401 that is slidably disposed in the middle of the support platform 1, a first driving device 402 for driving the displacement block 401 to move horizontally, a displacement plate 403 that is slidably disposed on the displacement block 401, a second driving device 404 for driving the displacement plate 403 to move longitudinally, and a plurality of shearing mechanisms 405 disposed on the displacement plate 403. The first driving device 402 and the second driving device 404 can be electric push cylinders or pneumatic push cylinders. The first driving device 402 has a built-in push rod that is connected to the displacement block 401, thereby pushing the displacement block 401 to move horizontally. The second driving device 404 has a built-in push rod that is connected to the displacement plate 403. The push rod moves to push the displacement plate 403 moves longitudinally, the first drive device 402 and the second drive device 404 can also be replaced by an electric screw or other platforms that achieve the same functions, which are all prior arts and will not be described in detail here; the shearing mechanism mentioned in the present application has been disclosed in the authorized and disclosed utility model case "Pneumatic Scissors" CN101947794A, and the structural principle of the pneumatic scissors has been disclosed. It is a product that can be purchased on the market, and the structure is well known. The corresponding model can be purchased according to production needs, so this application will not repeat it; the first drive device 402 is arranged on the support platform 1, and the second drive device 404 is rotatably arranged between the displacement plate 403 and the support platform 1.

[0026] The shearing device is set up to place the injection molded part on the positioning station. After completion, the first driving device is started. The displacement block is laterally moved and adjusted in position by the first driving device. During the transverse movement of the displacement block, the displacement plate and the shearing mechanism are driven to move laterally, so that the shearing mechanism is aligned with the injection molded part water outlet position. Then the second driving device drives the displacement plate to move upward. During the upward movement of the displacement plate, the shearing mechanism moves to the injection molded part water outlet position. Then the shearing mechanism shears the injection molded part water outlet position. After cutting off the excess water outlet residue, the second driving device drives the displacement plate to move downward and move it to the support platform. The new injection molded part is manually replaced. The shearing device does not require manual shearing of the injection molded part water outlet, and multiple shearing mechanisms can be set on the displacement plate, so that multiple injection molded parts can be sheared at the same time.

[0027] The shearing machine is provided with more than two groups, reference Figure 1 and Figure 5 One group of shearing machines is set at the front end of the support platform, and the other group is set at the rear end of the support platform. The shearing mechanisms in the two groups of shearing machines are staggered at intervals in front and back. When the injection molded parts are densely arranged in horizontal rows as shown in the attached figure, the shearing mechanisms occupy a certain width and cannot shear two adjacent water outlet positions at the same time. The two groups of front and back distribution settings can shear the water outlet positions of the densely arranged injection molded parts.

[0028] The positioning station 2 includes vertical plates 2a disposed on the top surface of the support platform 1 and arranged at intervals. The residual material position of the injection molded part can be inserted into the vertical plates, thereby initially positioning the injection molded part.

[0029] The spacing between the vertical plates 2a gradually narrows from top to bottom, making it easier for injection molded parts to be placed in the vertical plates.

[0030] The fixed station 3 includes a positioning plate 301 slidably arranged on the top surface of the supporting platform 1, a groove 302 arranged on the top surface of the supporting platform 1 and used to block the rear end of the injection molded part, and a third driving device 303 for driving the positioning plate 301 to move forward and backward. The fixed station is set up, when the injection molded part is placed in the vertical plate of the positioning station, the rear end of the injection molded part fits in the groove, the third driving device drives the positioning plate to move backward, and the injection molded part is stuck between the positioning plate and the groove to prevent the injection molded part from being displaced during use.

[0031] The positioning plate 301 is in the shape of a hook. The residual material of the injection molding nozzle is mostly tubular or square. The positioning plate in the shape of a hook is convenient for fixing the residual material of the injection molding nozzle.

[0032] A removal station 5 for removing the injection molded parts after shearing is provided above the support platform 1, and an inclined rod 6 for guiding the injection molded parts to slide out is provided above the support platform 1. The removal station 5 includes a support frame 501, a rotating shaft 502 rotatably arranged on the top of the support frame 501, a rotating rod 503 arranged on one side of the rotating shaft 502, a clamping device 504 arranged on the side of the rotating rod 503 away from the support frame 501 and used for clamping the injection molded parts, and a fourth driving device for driving the rotating rod 503 to rotate.

[0033] The setting of the moving workstation is that when the shearing machine completes shearing of the residual material at the sprue of the injection molded part, the fixed workstation releases the injection molded part, the fourth driving device drives the rotating shaft to rotate, the rotating shaft drives the rotating rod to rotate downward, and the clamping device under the rotating rod will clamp the residual material at the sprue of the injection molded part. Since the shearing machine has sheared and separated the injection molded part from the excess residual material at the sprue, the fourth driving device drives the residual material at the sprue of the injection molded part to rotate upward. When it rotates to the position of the inclined rod, the clamping device releases the excess residual material at the sprue, and the residual material at the sprue will be discharged through the guiding movement of the inclined rod.

[0034] The rotating shaft 502 is provided with connecting plates 505 on both sides thereof, and a pressure rod 506 is provided on the side of the connecting plate 505 away from the rotating shaft 502. When the rotating shaft rotates, the pressure rod will also press down the sheared part of the injection molded part. When the clamping device rotates upward, the pressure rod will also rotate simultaneously to prevent the injection molded part from shifting to the residual material position of the water outlet.

[0035] The fourth driving device includes a gear 507 disposed outside the rotating shaft 502 , a rack 508 slidably disposed on the support frame 501 , and a driving cylinder 509 for driving the rack 508 to move longitudinally. The rack 508 is meshed with the gear 507 .

[0036] The fourth driving device is set up, in which the driving cylinder drives the rack to move upward, the upward movement of the rack drives the gear to rotate, and the rotation of the gear drives the rotating shaft to rotate. After the driving cylinder reaches the lower stroke limit distance, the rotating rod and the clamping device will rotate to the inclined rod position. After the driving cylinder reaches the upper stroke limit distance, the rotating rod reaches the support platform position, and the clamping device will clamp the residual material at the injection molded part gate.
