[0002] Plastic is a material mainly composed of high - molecular synthetic resin polymer, infiltrated with various auxiliary materials or additives. It has plasticity and fluidity at specific temperatures and pressures, can be molded into a certain shape, and can maintain its shape unchanged under certain conditions. Therefore, plastic is also used to make various shaped toys. The relatively common plastic toys on the market are integrally injection - molded by an injection molding machine. Therefore, plastic toys have good integrity, and further make the appearance of plastic toys more beautiful. When producing toys that need to be assembled, this type of toy needs to be pre - injection - molded into two shells first, and then the two shells are glued together by artificial using glue to form a complete toy, or the docking and pressing are carried out using the clamping structure on the shell itself for assembly.

[0034] The linear moving seat 21 includes a linear moving seat body 211 with a hollow interior, and a dust cover 212 covering the linear moving seat body 211;

[0035] The upper edge side of the linear moving seat 21 is fixedly installed with a slide rail 213 by screws;

[0036] One side inside the linear moving seat 21 is fixedly installed with a plurality of L-shaped frames 214 for supporting the dust cover 212 by screws, and the other side inside the linear moving seat 21 is fixedly installed with a straight rack 215 by screws.

[0037] On both sides below the support table 22, support feet 221 with sliders on the inner side are fixedly installed by bolts. Inside one of the support feet 221 on one side, an L-shaped support plate 222 is welded and installed. A partition plate 223 is fixedly installed on the L-shaped support plate 222 by bolts. A speed reducer 224 is fixedly installed on the outer side of the lower end of the partition plate 223 by bolts. A driving motor 225 is fixedly assembled with the speed reducer 224. A driving gear 226 is located on the inner side of the lower end of the partition plate 223 and is assembled with the output end of the speed reducer 224 through a pin key. Specifically, the driving gear 226 is meshed and assembled with the straight rack 215. After starting the driving motor 225, the speed is adjusted through the speed reducer 224, so that the driving gear 226 meshes and moves with the straight rack 215, thereby driving the support table 22 to move on the linear moving seat 21.

[0038] On both sides of the upper end of the mold clamping frame 3, cross beams 31 with bearing holes are welded and installed. Specifically, the bearing seats 42 on the first mold clamping mechanism 4 and the second mold clamping mechanism 5 can be sleeved in the bearing holes on the cross beams 31, and then fixedly installed by bolts, so that the first mold clamping mechanism 4 and the second mold clamping mechanism 5 can be stably installed and can stably cooperate with each other to assemble the injection molded parts into toys.

[0039] The first mold clamping mechanism 4 includes a rotating plate 41 with a hollow center part. Bearing seats 42 are fixedly installed on both sides of the rotating plate 41. A rotating motor 43 fixedly installed with the mold clamping frame 3 and whose output end passes through the bearing seat 42 and is connected to the rotating plate 41. A telescopic cylinder 44 is fixedly installed at the center of the rotating plate 41 and whose output passes through the hollow part of the rotating plate 41. A pressing plate 45 is fixedly installed with the output end of the telescopic cylinder 44 by bolts. Spring buffers 46 are fixedly installed at the four corners of the pressing plate 45. A top plate 47 assembled with the spring buffers 46 and cooperating with the pressing plate 45 to sleeve the injection molded parts. An injection molded part mold clamping 48 integrally formed on the surface of the top plate 47, and an air delivery hose 49 arranged between the pressing plate 45 and the top plate 47 and cooperating with the top plate 47.

[0040] Bearing assembly heads 411 are fixedly installed on both sides of the rotating plate 41 by screws. Specifically, the bearing seats 42 can be fixed through the bearing assembly heads 411, and it is convenient for the output end of the rotating motor 43 to pass through the bearing seat 42 and be connected to the rotating plate 41, thereby driving the first mold clamping mechanism 4 to rotate integrally and cooperate with the second mold clamping mechanism 5 to assemble the toy injection molded parts;

[0041] On the side of the central hollow part of the rotating plate 41, guide holes 412 distributed in a ring are provided.

[0042] A circular guide post 451 is welded in the middle of the upper surface of the pressing plate 45. Specifically, the guide post 451 passes through the guide hole 412 of the rotating plate 41 and moves in the guide hole 412, which can improve the working stability of the telescopic cylinder 44.

[0043] The pressure plate 45 has buffer installation holes 452 at four corners corresponding to the spring buffer 46.

[0044] The pressing plate 45 is provided with tube holes 412 at equal intervals.

[0045] The spring buffer 46 includes a base 461 with a screw hole, a sleeve 462 welded to the center of the base 461, a connecting column 463 with a threaded hole at the end thereof, which passes through the sleeve 462 and is welded and fixed to the base 461, a pressure relief spring 464 sleeved on the connecting column 463, and a stud 465 screwed into the connecting column 463 to fix the top plate 47. Specifically, the sleeve 462 passes through the buffer installation hole 452, the base 461 abuts against the pressure plate 45 and is fixedly installed by bolts, the pressure relief spring 464 sleeved on the connecting column 463 contacts the top plate 47, and then passes through the top plate 47 through the stud 465 and is screwed into the connecting column 463, so that the top plate 47 can move according to the length of the stud 465, is supported and fixed by the pressure relief spring 464, and is limited by the connecting column 463.

[0046] The top plate 47 is provided with stud assembly holes 441 at four corners. Specifically, the studs 465 pass through the stud assembly holes 471 and are screwed into the connecting posts 463, so that the top plate 47 and the pressure plate 45 can be matched and installed.

[0047] The upper surface of the top plate 47 corresponding to the injection mold 48 is welded with a hollow steel tube 472, and an auxiliary spring 473 is mounted on the hollow steel tube 471. The hollow steel tube 472 passes through the top plate 47 and is connected to the injection mold 48. Specifically, the hollow steel tube 472 passes through the pipe hole 412 and is connected to the air hose 49. After the toy injection molded parts are assembled, the gas transported by the air hose 49 can be ejected through the hollow steel tube 472 to blow out the objects stuck in the injection mold 48. At the same time, the auxiliary spring 473 is used to assist in opening the top plate 47 and the pressure plate 45.

[0048] In use, the structures of the first mold clamping mechanism 4 and the second mold clamping mechanism 5 are the same. During operation, the telescopic air cylinder 44 is sequentially controlled to extend, so that the injection molded part mold clamping 48 sleeves the injection molded part from the injection molded part convex template 24. Then, the telescopic air cylinder 44 is controlled to retract and rotate upward by 90°, so that the top plates 47 face each other, and thus the injection molded part mold clamping 48 faces each other. The telescopic air cylinder 44 is controlled to extend, so that the top plates 47 in the first mold clamping mechanism 4 and the second mold clamping mechanism 5 move relatively until the injection molded part mold clamping 4 with the injection molded part is closed. At this time, the injection molded parts are fixed to each other to complete the assembly. Then, the telescopic air cylinder 44 is controlled to retract and separate, and at the same time rotate downward by 90°. After the rotation is completed, the gas conveyed by the air supply hose 49 is ejected through the hollow steel pipe 472 to blow out the object stuck in the injection molded part mold clamping 48. After the process of assembling a toy with injection molded parts is completed once, the above working steps are continuously cycled according to the setting.

[0049] It should be further noted that since the structures of the first mold clamping mechanism 4 and the second mold clamping mechanism 5 are the same, but most of the injection molded parts assembled into toys are still clamped in the injection molded part mold clamping 48 of the first mold clamping mechanism 4, and the front end of the workbench 1 corresponding to the mold clamping frame 3 is hollowed out. Therefore, the hollow part of the workbench 1 is located below the first mold clamping mechanism 4, which is convenient for the assembled toys to fall and be collected by the collection box.

[0050] The above embodiments of the present invention do not limit the protection scope of the present invention. The implementation manners of the present invention are not limited to this. All kinds of modifications, substitutions or changes made to the above structure of the present invention according to the above content of the present invention, in accordance with the common technical knowledge and customary means in the art, without departing from the above basic technical idea of the present invention, shall fall within the protection scope of the present invention.
