[0055] Specifically, as shown in the figure, Figure 8 The turnover driving part 420 includes a turnover cylinder 421 and a wedge block 422 arranged at the output end of the turnover cylinder 421; the turnover support frame 410 is rotatably arranged on the base 100 through a torsion spring, and the turnover cylinder 421 drives the turnover support frame 410 to rotate through the wedge block 422.

[0056] Next, the working principle of the injection molding part water gap cutting device 30 described above will be described:

[0057] The injection molding machine (not shown in the figure) completes the injection molding to obtain the injection molding semi-finished product 10, and the manipulator (not shown in the figure) takes out the injection molding semi-finished product 10 from the injection molding machine and puts it into the semi-finished product blanking cylinder 300;

[0058] As shown in the figure, Figure 4 At this time, the semi-finished product accommodating groove 520 is just located at the blanking opening directly below the semi-finished product blanking cylinder 300, so that the injection molding semi-finished product 10 falls into the semi-finished product accommodating groove 520 under the guidance of the semi-finished product blanking cylinder 300, and the injection molding semi-finished product 10 falls into the groove body from the blanking opening 521, and the semi-finished product supporting surface 523 supports the injection molding semi-finished product 10; it should be noted that in the present application, the structure of the semi-finished product accommodating groove 520 is obtained according to the injection molding semi-finished product 10, and the semi-finished product accommodating groove 520 is of an open structure and can accommodate half of the injection molding semi-finished product 10;

[0059] Then, the conveying frame driving part 530 drives the semi-finished product conveying frame 510 to move to one side of the semi-finished product stacking device 400, and stacks the injection molding semi-finished product 10 in the semi-finished product accommodating groove 520 on the conical stacking column 430;

[0060] After the stacking is completed, the conveying frame driving part 530 drives the semi-finished product conveying frame 510 to move to the side of the semi-finished product falling cylinder 300 for resetting; it should be pointed out that when the semi-finished product 10 is stacked on the tapered stacking column 430, the semi-finished product stacking extrusion surface 524 will exert an extrusion force on the semi-finished product 10, causing the semi-finished product 10 to expand slightly, so that the inner wall of the semi-finished product 10 and the tapered stacking column 430 generate a friction force, so that when the semi-finished product conveying frame 510 resets, the semi-finished product 10 can smoothly separate from the stripping opening 522 and rest on the tapered stacking column 430;

[0061] When the semi-finished product containing groove 520 reaches directly below the semi-finished product falling cylinder 300 again, the mechanical arm takes out the semi-finished product 10 from the injection molding machine and puts it into the semi-finished product falling cylinder 300, and the semi-finished product 10 falls into the semi-finished product containing groove 520 under the guidance of the semi-finished product falling cylinder 300, and the conveying frame driving part 530 drives the semi-finished product conveying frame 510 to move to the side of the semi-finished product stacking device 400 again, and stacks the semi-finished product 10 in the semi-finished product containing groove 520 on the tapered stacking column 430, so that a plurality of semi-finished products 10 can be stacked on the tapered stacking column 430;

[0062] After a certain number of semi-finished products 10 are stacked, the conveying frame driving part 530 drives the semi-finished product conveying frame 510 to move to the side of the semi-finished product stacking device 400, and the semi-finished product support surface 523 of the semi-finished product containing groove 520 supports the semi-finished product 10, and the semi-finished product extrusion surface 524 of the semi-finished product containing groove 520 extrudes the semi-finished product 10; as Figure 5 shown, this step is very necessary, and the semi-finished product containing groove 520 supports and extrudes a plurality of semi-finished products 10, which prepares for the subsequent stable cutting of the water gap material by the water gap cutting device 200;

[0063] as Figure 5As shown, the support frame driving part 220 drives the movement of the moving support frame 210 to the side of the semi-finished product stacking device 400, while the rotating driving part 230 drives the rotation of the nozzle cutting pipe drill 240, the nozzle material is cut off by the nozzle cutting ring cutter 242, the cut-off nozzle material is recycled by the nozzle receiving cavity 241, and the burrs left by the nozzle material are polished by the nozzle polishing ring surface 243, thereby obtaining a plurality of stacked injection molded part products 20; in the present application, the nozzle cutting ring cutter 242 cuts off the nozzle material by rotating, and the cut-off nozzle material will enter the nozzle receiving cavity 241 along with the continuous advancement of the nozzle cutting pipe drill 240, realizing the recycling of waste materials, while not affecting the smooth progress of the cutting work; further, after the nozzle material is cut off by the nozzle cutting ring cutter 242, part connected with the nozzle material will leave burrs, and the nozzle polishing ring surface 243 will polish the burrs along with the rotation of the nozzle cutting pipe drill 240;

[0064] After the cutting is completed, the nozzle cutting device 200 is reset, the turnover driving part 420 drives the turnover of the turnover support frame 410, so that the plurality of stacked injection molded part products 20 are turned from the horizontal state to the vertical state (as shown in Figure 6 The worker takes away the plurality of stacked injection molded part products 20, and each device is reset to repeat the previous steps.

[0065] In the present application, the semi-finished product accommodating groove 520 plays a very important bridge role:

[0066] When the semi-finished product accommodating groove 520 is directly below the semi-finished product blanking cylinder 300, it can cooperate with the semi-finished product blanking cylinder 300 to receive the injection molded part semi-finished product 10;

[0067] The semi-finished product accommodating groove 520 can be driven by the driving part to transport the injection molded part semi-finished product 10 to the semi-finished product stacking device 400, the semi-finished product stacking extrusion surface 524 cooperates with the conical stacking column 430 to generate friction force between the inner wall of the injection molded part semi-finished product 10 and the conical stacking column 430, and cooperates with the stripping opening 522 to make the injection molded part semi-finished product 10 stay on the conical stacking column 430;

[0068] After a certain number of injection molded part semi-finished products 10 are stacked, the semi-finished product supporting surface 523 of the semi-finished product accommodating groove 520 supports the injection molded part semi-finished product 10, and the semi-finished product stacking extrusion surface 524 of the semi-finished product accommodating groove 520 extrudes the injection molded part semi-finished product 10, so that the plurality of injection molded part semi-finished products 10 can be stably supported and extruded, so that the nozzle cutting device 200 can stably cut off the nozzle material;

[0069] When the turnover driving part 420 drives the turnover support frame 410 to turn over, since the semi-finished product accommodating groove 520 is of an open structure, the turnover of the injection molded part semi-finished product 10 is not hindered.

[0070] The application further discloses an injection molded part production process, which is realized by the injection molded part sprue cutting device 30 and comprises the following steps.

[0071] Step one, an injection molding machine completes injection molding to obtain an injection molded part semi-finished product, a manipulator takes out the injection molded part semi-finished product from the injection molding machine and puts it into a semi-finished product falling cylinder.

[0072] Step two, the injection molded part semi-finished product slides into the semi-finished product accommodating groove under the guidance of the semi-finished product falling cylinder.

[0073] Step three, a conveying frame driving part drives the semi-finished product conveying frame to move to one side of the semi-finished product stacking device, and the injection molded part semi-finished product in the semi-finished product accommodating groove is stacked on the conical material stacking column.

[0074] Step four, the conveying frame driving part drives the semi-finished product conveying frame to move to one side of the semi-finished product falling cylinder.

[0075] Step five, steps one, two, three and four are repeated, so that the conical material stacking column is stacked with a plurality of injection molded part semi-finished products.

[0076] Step six, the conveying frame driving part drives the semi-finished product conveying frame to move to one side of the semi-finished product stacking device, the semi-finished product semi-finished product is supported by the semi-finished product supporting surface of the semi-finished product accommodating groove, and the semi-finished product semi-finished product is extruded by the semi-finished product extrusion surface of the semi-finished product accommodating groove.

[0077] Step seven, a support frame driving part drives the movable support frame to move to one side of the semi-finished product stacking device, a rotating driving part drives the sprue cutting pipe to rotate, a sprue cutting ring cutter cuts the sprue material, a sprue accommodating cavity recycles the cut sprue material, and a sprue polishing ring surface polishes the burrs left by the sprue material, so that a plurality of stacked injection molded part products are obtained.

[0078] Step eight, the sprue cutting device is reset, and a turnover driving part drives the turnover support frame to turn over, so that the plurality of stacked injection molded part products are turned from a horizontal state to a vertical state.

[0079] As known from the above, the injection molded part sprue cutting device is used for stacking a plurality of injection molded part semi-finished products 10 at the semi-finished product stacking device 400, and then cutting the sprue material of the plurality of injection molded part semi-finished products 10 by using the sprue cutting device 200, so that the efficiency of cutting the sprue material is improved, and the consistency of the injection molded part products is ensured.

[0080] Further, the injection molding part water gap cutting device of the present application, each device is ingeniously matched, so that the overall function of the device can be realized, for example:

[0081] When the injection molding part semi-finished product 10 is stacked on the conical stacking column 430, the semi-finished product stacking extrusion surface 524 can exert an extrusion force on the injection molding part semi-finished product 10, so that the injection molding part semi-finished product 10 is slightly expanded and deformed, thereby generating a friction force between the inner wall of the injection molding part semi-finished product 10 and the conical stacking column 430. Thus, when the semi-finished product conveying frame 510 is reset, the injection molding part semi-finished product 10 can smoothly separate from the stripping opening 522 and rest on the conical stacking column 430;

[0082] After a certain number of injection molding part semi-finished products 10 are stacked, the conveying frame driving part 530 drives the semi-finished product conveying frame 510 to move to the semi-finished product stacking device 400 side, and the semi-finished product support surface 523 of the semi-finished product containing groove 520 supports the injection molding part semi-finished product 10, and the semi-finished product stacking extrusion surface 524 of the semi-finished product containing groove 520 extrudes the injection molding part semi-finished product 10;

[0083] The water gap cutting ring cutter 242 cuts off the water gap material by rotating, and just as the water gap cutting pipe drill 240 continuously advances, the cut-off water gap material enters the water gap storage cavity 241, realizing the recycling of waste materials, and at the same time, it does not affect the smooth cutting-off work; after the water gap material is cut off by the water gap cutting ring cutter 242, the part connected with the water gap material will leave a burr, and with the rotation of the water gap cutting pipe drill 240, the water gap polishing ring surface 243 can polish the burr flat;

[0084] When the semi-finished product containing groove 520 is directly below the semi-finished product material dropping cylinder 300, it can cooperate with the semi-finished product material dropping cylinder 300 to receive the injection molding part semi-finished product 10; the semi-finished product containing groove 520 can convey the injection molding part semi-finished product 10 to the semi-finished product stacking device 400 under the driving of the driving part, the semi-finished product stacking extrusion surface 524 cooperates with the conical stacking column 430 to generate a friction force between the inner wall of the injection molding part semi-finished product 10 and the conical stacking column 430, and cooperates with the stripping opening 522 to make the injection molding part semi-finished product 10 rest on the conical stacking column 430; after a certain number of injection molding part semi-finished products 10 are stacked, the semi-finished product support surface 523 of the semi-finished product containing groove 520 supports the injection molding part semi-finished product 10, and the semi-finished product stacking extrusion surface 524 of the semi-finished product containing groove 520 extrudes the injection molding part semi-finished product 10, so that the injection molding part semi-finished product 10 can be stably supported and extruded, so that the water gap cutting device 200 can stably cut off the water gap material; when the turnover driving part 420 drives the turnover support frame 410 to turn over, since the semi-finished product containing groove 520 is an open structure, it will not hinder the turnover of the injection molding part semi-finished product 10.

[0085] The above embodiments only express several implementation manners of the present application, which are described in a more specific and detailed manner, but cannot be understood as a limitation on the patent scope of the present application. It should be noted that, for ordinary skilled persons in the art, several modifications and improvements can be made without departing from the concept of the present application, which all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
