[0032] As Figures 7 - 9 shown;

[0033] Since the plastic toy processing device includes semi-circular flaps 101, the semi-circular flaps 101 are divided into two layers, there are two semi-circular flaps 101 on the upper side and two semi-circular flaps 101 on the lower side. A mold groove 106 is arranged on the inner side of the semi-circular flaps 101. Four semi-circular flaps 101 form an annular mold, and an annular space is arranged inside the annular mold. An injection tube 103 is arranged on one of the semi-circular flaps 101, and the injection tube 103 communicates with the annular space. There are two annular molds, and the two annular molds are connected by a chain link. Molten plastic can be injected into the annular space through the injection tube 103. After waiting for the plastic to cool, a plastic ring is formed; then the four semi-circular flaps 101 can be removed from the formed plastic ring, which is convenient for demolding. The two annular molds can be connected by a chain link, that is, the two annular molds are inserted into the inner side of another annular mold. At this time, molten plastic is injected into the two annular molds, and finally two complete plastic rings can be formed, and the two plastic rings are connected by a chain link. Both of the two complete plastic rings have no break, ensuring the strength of the two plastic rings.

[0034] On one of the semi-circular flaps 101, an injection tube 103 is specially arranged. One end of the injection tube 103 is communicated with an external plastic melting device, and the other end is accurately docked with the annular space inside the annular mold to ensure that the molten plastic can be smoothly injected into it. It is worth mentioning that the device is equipped with two such annular molds, and the two annular molds are connected by a chain link. The specific operation is that the two annular molds are inserted into the inner side of another annular mold, thus forming a special combined structure.

[0035] In the actual production process, first, the molten plastic in a high-temperature molten state is injected into the annular space through the injection tube 103. After the injection is completed, it enters the waiting stage. As time goes by, the plastic gradually cools and solidifies in a relatively low-temperature environment, and finally forms the required plastic ring shape. When the plastic is completely cooled and shaped, the staff can carefully remove the four semi-circular flaps 101 from the formed plastic ring. Since the four semi-circular flaps 101 are all convenient to separate, the entire demolding process becomes extremely convenient, greatly improving the production efficiency.

[0036] After two annular molds are connected by a chain link, molten plastic is injected into these two interconnected annular molds simultaneously. After cooling and solidification, two complete plastic rings can be successfully formed, and the two plastic rings are in a state of chain link connection. Particularly crucial is that neither of these two complete plastic rings has any breaks. This seamless connection method greatly guarantees the strength of the two plastic rings, making the produced plastic toy parts have significant advantages in terms of quality and durability, and being able to better meet the market's demand for high-quality plastic toys.

[0037] It is also possible to connect the chain links between multiple annular molds. During operation, just follow the way of connecting two annular molds pairwise, and gradually add the third, fourth, and even more annular molds to the connection system in sequence. For each additional annular mold, the number of injection pipes 103 can be increased accordingly to ensure that the molten plastic can be injected into each annular space in a timely and uniform manner. After the chain link connection of multiple annular molds, the production efficiency has achieved a qualitative leap. One injection process can produce multiple plastic rings connected by chain links.

[0038] In addition, this processing device also supports a more flexible connection method, that is, one annular mold is connected to multiple annular molds by chain links. In actual operation, first take an assembled annular mold as the starting end, and then, according to the established chain link connection rules, connect multiple annular molds to this starting annular mold one by one in sequence. A chain-like structure is formed with one starting annular mold in series with multiple subsequent annular molds.

[0039] For some specially designed plastic toys, a set of chain link plastic rings of different sizes or with a specific arrangement order may be required. By connecting one annular mold to multiple annular molds by chain links, production personnel can flexibly adjust the specifications of each annular mold, such as changing the size and shape of the mold groove 106, or selecting semi-ring petals 101 of different materials to manufacture plastic rings with different characteristics. When injecting molten plastic, the injection volume and injection speed can be accurately controlled according to the characteristics of each annular mold, so as to produce a set of chain link plastic ring combinations that meet the design requirements in terms of size, material, performance, etc. This not only greatly expands the application scope of this processing device, but also helps toy manufacturers quickly respond to the market's demand for personalized and diversified plastic toys.

[0040] As Figures 7 - 9 shown;

[0041] Since a lug 102 is fixed on each of the semi-ring petals 101, and an inclined surface 105 is provided between two oppositely arranged lugs 102, an object can be inserted between the two lugs 102 during demolding;

[0042] When the injection molding of the plastic ring is completed and the demolding process begins, the staff can accurately insert a special demolding tool, such as a wedge block or a special pry bar, between the two oppositely arranged lugs 102. Due to the existence of the inclined surface 105, when the demolding tool applies external force, according to the principle of mechanics, this external force will be decomposed along the inclined surface 105. Part of the force acts vertically on the lug 102 to provide a stable point of force for the demolding tool; the other part of the force is along the circumferential direction of the semi-ring petal 101, generating a component force that causes the semi-ring petal 101 to separate from the molded plastic ring. As the external force continues to be applied, the semi-ring petal 101 gradually separates from the plastic ring, thereby achieving an efficient and lossless demolding process.

[0043] like Figures 7 - 10 As shown;

[0044] Since a convex column 104 is welded on one side of each of the semi-ring petals 101, a clamp is clamped on each annular mold, and the clamp includes a clamp rod 201, a square hole 202 and a threaded column 203. The two clamp rods 201 are arranged opposite to each other, and a threaded column 203 is inserted in both ends of the two clamp rods 201 with a clearance fit. Nuts are threadedly connected at both ends of each threaded column 203, and two square holes 202 are provided on each clamp rod 201. The two clamp rods 201 are clamped on the four semi-ring petals 101 on the annular mold, and the four convex columns 104 are respectively inserted in the four square holes 202.

[0045] For each annular mold, in order to achieve a stable clamping of its component semi-annular petals 101, a corresponding clamp is specially equipped. The clamp is exquisitely constructed, and is mainly composed of key components such as a clamping rod 201, a square hole 202 and a threaded column 203. Among them, there are two clamping rods 201, which are arranged relatively to form a embracing trend for the annular mold. The clamping rod 201 is made of high-strength alloy steel to ensure that it will not be deformed during the clamping process, so as to reliably fix the semi-annular petals 101. The length of the clamping rod 201 is customized according to the outer diameter of the annular mold, generally slightly larger than the circumference of the annular mold, to ensure that the four semi-annular petals 101 on the annular mold can be fully covered and clamped.

[0046] In the design of the clamping rod 201, holes for inserting the threaded column 203 are carefully set at both ends of each clamping rod 201, and the holes and the threaded column 203 are matched with clearance. This matching method can not only ensure that the threaded column 203 can be inserted into the hole relatively smoothly, but also ensure the accuracy of the connection to a certain extent. Both ends of each threaded column 203 are designed with standard threads, and through the threaded connection with the nut, the relative position of the two clamping rods 201 can be accurately adjusted and fixed. The nut is selected from a high-strength nut that is compatible with the threaded column 203. When tightening the nut, a suitable torque can be applied according to actual needs, so that the two clamping rods 201 are tightly clamped on the annular mold.

[0047] When the fixture is installed, the two clamping rods 201 are in a relative state and tightly clamped on the four semi-circular petals 101 of the annular mold. At this time, the four protruding posts 104 on the four semi-circular petals 101 will accurately insert into the corresponding square holes 202 on the four clamping rods 201 respectively. This design not only realizes the stable clamping of each semi-circular petal 101 of the annular mold, but also plays a positioning role through the cooperation of the protruding post 104 and the square hole 202, ensuring that the semi-circular petal 101 will not be displaced during the injection molding process, thus guaranteeing the precision and quality of the plastic ring molding.

[0048] As Figures 10 - 12 shown;

[0049] Since both ends of the right-angle rod 401 are respectively fixed on one of the two clamping rods 201 of the fixture, the right-angle rod 401 is hinged on the hinge frame 404, the hinge frame 404 is fixed on the upper part of the column 306, the column 306 is welded on the chassis 301, a separating column 307 is welded on the chassis 301, a pointed head 308 is fixed at the upper end of the separating column 307, a spring 405 is arranged between the column 306 and the right-angle rod 401, the chassis 301 and the column 306 suspend and support the hinge frame 404, the right-angle rod 401 can rotate on the hinge frame 404, and then the two fixtures can rotate following the right-angle rod 401. The right-angle rod 401 supports the two fixtures horizontally and vertically, and then supports the two annular molds horizontally and vertically, so that the two annular molds maintain a state of being connected in a chain with each other. At this time, it is convenient to carry out injection molding towards the two annular molds;

[0050] The spring 405 continuously provides upward or downward elastic force to the right-angle rod 401. Under the action of the elastic force, the right-angle rod 401 can jitter up and down regularly through the spring 405. Since the right-angle rod 401 is closely connected with the two fixtures, this kind of jitter will be quickly transmitted to the two fixtures and the two annular molds placed on the fixtures, so that the two annular molds can jitter up and down. During the jittering process of the annular mold, the plastic being injection molded inside the mold is affected by the vibration and can flow more evenly and fill the entire internal space of the annular mold. This design effectively avoids the situation of local accumulation or insufficient filling of the plastic in the mold, greatly improves the molding quality of the plastic ring, makes the produced plastic ring more uniform in density, thickness, etc., and significantly improves the product quality.

[0051] As Figures 11 - 12 shown;

[0052] Since a convex rod 402 is fixed to the upper side of the right-angle rod 401, and a triangular head 403 is fixed to the upper part of the convex rod 402, a second telescopic rod 305 is fixed to the column 306, and a cylinder 309 is fixed to the end of the second telescopic rod 305. The cylinder 309 presses on the convex rod 402. When the second telescopic rod 305 expands and contracts, it drives the cylinder 309 to move back and forth to push the right-angle rod 401, thereby driving the right-angle rod 401 to vibrate up and down;

[0053] When the device is running, the second telescopic rod 305 starts to expand and contract according to the set program or the instructions issued by the operator. When the second telescopic rod 305 extends forward, it drives the connected cylinder 309 to move forward synchronously. Since the cylinder 309 presses on the convex rod 402, as the cylinder 309 moves forward, a frictional force is generated between it and the convex rod 402. At the same time, the front end face of the cylinder 309 exerts a squeezing force on the convex rod 402 in the forward and downward direction. This squeezing force will be decomposed into a horizontal component force and a vertical downward component force. The horizontal component force causes the convex rod 402 and the connected right-angle rod 401 to have a tendency to rotate clockwise around the hinge point of the hinge frame 404, while the vertical downward component force increases the downward pressure of the right-angle rod 401 to a certain extent. The expansion and contraction action of the second telescopic rod 305 is successfully converted into the up and down vibration of the right-angle rod 401, thereby driving the two clamps and the two annular molds connected to the right-angle rod 401 to vibrate up and down, so that the plastic inside the two annular molds can fill the entire mold space more evenly during the injection molding process, significantly improving the molding quality and production efficiency of plastic toys.

[0054] As Figures 11 - 12 shown;

[0055] Since the upper end of the vertical column 306 is fixed with a first telescopic rod 304, the end of the first telescopic rod 304 is fixed with a pressing strip 303, and a triangular groove 302 is arranged on the lower side of the pressing strip 303. The triangular groove 302 can press on the triangular head 403. When it is necessary to fix the right-angle rod 401, the operator issues an instruction through the control system of the device to drive the first telescopic rod 304 to start working. After the motor inside the first telescopic rod 304 receives the instruction, it starts the screw drive mechanism, causing the first telescopic rod 304 to gradually shorten. As the first telescopic rod 304 shortens, the connected pressing strip 303 moves downward synchronously. During the downward movement of the pressing strip 303, the triangular groove 302 gradually approaches and aligns with the triangular head 403. When the triangular groove 302 contacts the triangular head 403, as the pressing strip 303 continues to move downward, the inner wall of the triangular groove 302 begins to exert pressure on the side surface of the triangular head 403. Due to the special shape design of the triangular groove 302 and the triangular head 403, this pressure will generate component forces in the horizontal and vertical directions. The horizontal component force restricts the triangular head 403 in the horizontal direction and prevents it from undergoing lateral displacement; the vertical component force further increases the pressure at the connection between the triangular head 403 and the convex rod 402, firmly fixing the convex rod 402 as well. Finally, the triangular groove 302 of the pressing strip 303 tightly presses on the triangular head 403, successfully fixing the triangular head 403 and the connected convex rod 402, thereby realizing the stable fixation of the right-angle rod 401, meeting the requirement for fixing the position of the right-angle rod 401 in a specific working state of the device, and ensuring the smooth progress of the entire plastic toy processing process.
