Description

Technical Field

[0001] This invention relates to the field of toy manufacturing, and in particular to a plastic toy manufacturing system and method. Background Technology

[0002] Foamed plastics are a type of polymer material formed by dispersing a large number of gas micropores within solid plastic. They possess properties such as light weight, heat insulation, sound absorption, and shock absorption, and their dielectric properties are superior to those of the matrix resin, making them widely applicable. Almost all types of plastics can be made into foamed plastics, and foam molding has become an important field in plastics processing.

[0003] Foam plastic airplane toys are popular because they can be thrown and fly. When manufacturing foam plastic airplane toys, flight testing is required to ensure the quality of the toys. However, existing processing systems cannot perform flight testing on airplane toys. Summary of the Invention

[0004] The purpose of this invention is to provide a plastic toy processing system and method that can perform flight testing on airplane toys.

[0005] The objective of this invention is achieved through the following technical solution:

[0006] A plastic toy processing system includes an upper mold base with legs at each of its four corners, an injection joint mounted on the upper mold base, and a lower mold base located below the upper mold base. The lower side of the upper mold base has an upper mold cavity, and the upper side of the lower mold base has a lower mold cavity. When the upper and lower mold bases are closed, the upper and lower mold cavities form an aircraft-shaped cavity. The injection joint is connected to the upper mold cavity. The lower mold cavity has through holes at both wings, and the upper mold cavity has two corresponding mating holes. Launch plates slide within the two through holes, and the front ends of the two launch plates have mold cavity holes.

[0007] The rear ends of the two launch plates are fixed to the crossbar.

[0008] A sliding rod frame slides through the crossbar, and a square rod is vertically fixed to the rear end of the upper mold base. The rear end of the sliding rod frame is slidably connected to the square rod, and a spring I is provided between the sliding rod frame and the upper mold base.

[0009] The upper mold base is inclined with the front higher than the rear, and a fixed shaft is provided at the rear end of the upper mold base. The rear end of the lower mold base rotates on the fixed shaft. A limit plate is fixed on the fixed shaft. Arc-shaped teeth are fixed on both sides of the lower mold base. A drive shaft rotates on the upper mold base, and the drive shaft is meshed with the two arc-shaped teeth for transmission.

[0010] The rear end of the slide bar frame has a rotating roller that rolls on the limiting curved plate.

[0011] The lower mold base is provided with two hook plates on its lower side, and a spring II is provided between the slide bar frame and the cross frame.

[0012] The lower mold base is provided with an electric telescopic rod on its lower side, and the free end of the electric telescopic rod is provided with a push plate.

[0013] The limiting curved plate consists of a free section and a guide section. The upper end of the free section is fixedly connected to the fixed shaft, and the guide section is fixed to the lower end of the free section.

[0014] Each of the two launch plates has a sliding push plate that can slide into the two mold cavity holes respectively. Each of the two push plates has a fixed reset plate. A spring III is provided between the reset plate and the corresponding launch plate. Each of the two mating holes has a mating block.

[0015] The method for processing a plastic toy using the aforementioned plastic toy processing system includes the following steps:

[0016] S1. The drive shaft rotates, which in turn drives the lower mold base to rotate on the fixed shaft, thus completing the mold closing.

[0017] S2. Molten plastic is injected into the aircraft cavity through the injection molding joint and cooled to obtain a plastic airplane-shaped toy.

[0018] S3. The reverse drive shaft rotates, causing the lower mold base to rotate and separate from the upper mold base. During this process, the roller rolls on the limiting curved plate through the elastic force of spring I, which in turn causes the two launch plates to control the two wings of the aircraft through the two mold cavity holes, separating them from the lower mold base and the upper mold base respectively.

[0019] S4. As the lower mold base continues to rotate, when the cross frame rises to fit against the lower side of the lower mold base, it loses the limiting position of the two hook plates. The elastic force of spring II will push the cross frame forward and slide quickly, thereby causing the two launch plates to move the toy airplane. The cross frame stops at the front end of the two through holes. The toy airplane continues to move forward due to inertia, thus flying out between the lower mold base and the upper mold base, forming a quality test of the toy airplane.

[0020] S5. Control the lower mold base to rotate, and at the same time push the push plate through the electric telescopic rod to reset the cross frame, and finally complete the mold closing, so that injection molding can be performed again. Attached Figure Description

[0037] like Figure 1-12 As shown:

[0038] A plastic toy processing system includes an upper mold base 101, an injection joint 102, an upper mold cavity 105, a mating hole 106, a lower mold base 201, a lower mold cavity 202, a through-hole 203, a launch plate 305, and a mold cavity hole 307. Support legs are provided at each of the four corners of the upper mold base 101. The injection joint 102 is disposed on the upper mold base 101. The lower mold base 201 is disposed below the upper mold base 101. The upper mold cavity 105 is disposed on the lower side of the upper mold base 101, and the lower mold cavity 202 is disposed on... On the upper side of the lower mold base 201, when the upper mold base 101 and the lower mold base 201 are closed, the upper mold cavity 105 and the lower mold cavity 202 form an aircraft cavity. The injection joint 102 is connected to the upper mold cavity 105. Two through holes 203 are respectively set at the two wings of the lower mold cavity 202. Two mating holes 106 are set at the corresponding positions of the upper mold cavity 105. Two launch plates 305 slide in the two through holes 203 respectively. The front end of each of the two launch plates 305 is provided with a mold cavity hole 307.

[0039] During processing, the injection joint 102 is connected to the plastic supply equipment in the molten state, and then the lower mold base 201 is controlled to move upward and fit against the lower side of the upper mold base 101, thereby forming the mold closing of the upper mold base 101 and the lower mold base 201. After the mold is closed, the upper mold cavity 105 and the lower mold cavity 202 form an aircraft cavity; at this time, the lower end of the launch plate 305 is located in the through hole 203, and the upper end is located in the mating hole 106. The mold cavity hole 307 is connected to the aircraft cavity to ensure the shape of the aircraft cavity. At the same time, the two mold cavity holes 307 are located at the wing positions of the two aircraft cavities respectively.

[0040] Molten plastic is injected into the aircraft mold cavity. After cooling, the upper mold base 101 and lower mold base 201 are separated. At the same time, two launch plates 305 are moved to the middle of the upper mold base 101 and lower mold base 201. Then, the two launch plates 305 control the two wings of the airplane toy through the two mold cavity holes 307, so that the airplane toy is separated from the upper mold cavity 105 and lower mold cavity 202. Then, the two launch plates 305 are pushed forward and moved quickly and stopped quickly, so that the airplane toy is launched forward by inertia, thus forming the separation of the airplane toy from the processing system. At the same time, the quality of the airplane toy can be detected according to the flight distance and flight status, thereby achieving the purpose of separating the airplane toy from the processing system while detecting the quality of the airplane toy.

[0041] Further:

[0042] The crossbar 304 is fixed to the rear end of the two launch plates 305.

[0043] By setting up the crossbar 304, the two launch plates 305 can be moved and stopped simultaneously, thereby ensuring that the forces on both wings of the aircraft are the same when the aircraft is launched, thus ensuring the detection effect of the aircraft.

[0044] Further:

[0045] The slide bar 301 slides through the crossbar 304, the square bar 204 is vertically fixed to the rear end of the upper mold base 101, the rear end of the slide bar 301 is slidably connected to the square bar 204, and the spring I 303 is disposed between the slide bar 301 and the upper mold base 101.

[0046] The square rod 204 forms a limit on the slide rod frame 301, and the slide rod frame 301 limits the cross frame 304. The elastic force of the spring I 303 pushes the slide rod frame 301 to press against the square rod 204 away from the end of the upper mold base 101. This allows the lower ends of the two launching plates 305 to be located in the through hole 203, and the two mold cavity holes 307 and the lower mold cavity 202 to be in a mating position.

[0047] like Figure 1-12 As shown:

[0048] The upper mold base 101 is inclined with the front higher than the rear. The fixed shaft 103 is fixed to the rear end of the upper mold base 101. The rear end of the lower mold base 201 rotates on the fixed shaft 103. The limiting curved plate 104 is fixed on the fixed shaft 103. Two arc-shaped teeth 206 are respectively fixed on both sides of the lower mold base 201. The drive shaft 207 rotates on the upper mold base 101. The drive shaft 207 is meshed with the two arc-shaped teeth 206 for transmission.

[0049] A first motor is installed on the upper mold base 101. The first motor drives the drive shaft 207 to rotate, which in turn causes the drive shaft 207 to mesh with two arc-shaped teeth 206, thereby causing the lower mold base 201 to rotate on the fixed shaft 103, thus completing the opening or closing of the lower mold base 201 and the upper mold base 101.

[0050] Due to the inclined setting of the upper mold base 101, the lower mold base 201 is in a horizontal state when the mold is opened, which makes it easy for the cross frame 304 to drive the two launch plates 305 to move forward horizontally, thus ensuring the launching effect on the airplane toy.

[0051] Simultaneously, through the setting of the limiting curved plate 104, when the lower mold base 201 rotates downward during mold opening, the lower mold base 201 will drive the slide rod frame 301 to rotate synchronously through the square rod 204, so that the rear end of the slide rod frame 301 slides on the limiting curved plate 104. Through the guidance of the limiting curved plate 104, a compression is formed on the slide rod frame 301, which in turn causes the slide rod frame 301 to compress the spring I 303, causing the slide rod frame 301 to move towards the lower mold base 201. Then, through the cross frame 304, the two launch plates 305 move upward on the lower mold base 201, so that when the system opens the mold, the two launch plates 305 move between the upper mold base 101 and the lower mold base 201, which facilitates the separation of the toy airplane from the upper mold cavity 105 and the lower mold cavity 202.

[0052] Further:

[0053] The roller 302 rotates at the rear end of the slide bar frame 301 and rolls on the limiting curved plate 104.

[0054] By setting the rollers 302, the sliding contact between the slide bar frame 301 and the limiting curved plate 104 is transformed into rolling sliding, ensuring the smoothness of mold opening or closing.

[0055] like Figure 1-12 As shown:

[0056] Two hook plates 205 are fixed to the lower side of the lower mold base 201, and spring II 306 is disposed between the slide bar frame 301 and the cross frame 304.

[0057] By setting two hook plates 205, the cross frame 304 is limited, so that the elastic force of spring II 306 can push the cross frame 304 forward to press against the two hook plates 205.

[0058] During mold opening, the limiting curved plate 104 guides the roller 302, causing the slide bar 301 to move towards the lower mold base 201 against the elastic force of spring I 303. This continues until the slide bar 301 drives the crossbar 304 to adhere to the lower side of the lower mold base 201. The crossbar 304 then loses the limiting force of the two hook plates 205 and, influenced by the elastic force of spring II 306, moves rapidly forward on the slide bar 301. This, in turn, drives the two launching plates 305 to move rapidly forward until the crossbar 304 slides to the front end of the two through holes 203 and is limited by them, causing the crossbar 304 to stop sliding. This causes the airplane toy to be launched forward by inertia, thus separating the airplane toy from the processing system. Simultaneously, the quality of the airplane toy can be inspected based on its flight distance and flight status, achieving the goal of separating the airplane toy from the processing system while simultaneously inspecting its quality.

[0059] like Figure 1-12 As shown:

[0060] The electric telescopic rod 502 is provided on the lower side of the lower mold base 201, and the free end of the electric telescopic rod 502 is provided with a push plate 501.

[0061] As the crossbar 304 slides to the front end of the two through holes 203, it contacts the push plate 501 and triggers the switch, controlling the extension of the electric telescopic rod 502. This causes the push plate 501 to push the crossbar 304 back until it moves to the two hook plates 205. As the lower mold base 201 rotates during mold closing, the slide bar 301 gradually moves away from the lower mold base 201 under the force of the spring I 303, which in turn causes the crossbar 304 to move until it disengages from the push plate 501. The crossbar 304 then continues to be limited by the two hook plates 205, and the trigger switch of the push plate 501 loses its triggering function. The electric telescopic rod 502 automatically retracts back to its original position.

[0062] like Figure 1-12 As shown:

[0063] The limiting curved plate 104 is composed of a free section 104a and a guide section 104b. The upper end of the free section 104a is fixedly connected to the fixed shaft 103, and the guide section 104b is fixed to the lower end of the free section 104a.

[0064] By setting the guide section 104b, a rolling guide limit is formed for the roller 302, so that the slide bar frame 301 can slide on the square bar 204. As the lower mold base 201 rotates, after the roller 302 rolls to the free section 104a, the slide bar frame 301 can remain stationary on the square bar 204; thus providing time for the electric telescopic rod 502 to control the crossbar 304 to slide back.

[0065] like Figure 1-12 As shown:

[0066] Two push plates 401 pass through two launch plates 305 respectively, and the two push plates 401 can slide into two mold cavity holes 307 respectively. Two reset plates 402 are fixed on the two push plates 401 respectively. A spring Ⅲ 403 is provided between the reset plate 402 and the corresponding launch plate 305. A mating block 107 is provided in each of the two mating holes 106.

[0067] During mold closing, the two reset plates 402 are guided and limited by the two mating blocks 107, causing the two push plates 401 to slide into the two launch plates 305. During mold opening, the two reset plates 402 lose the limitation of the two mating blocks 107, and the two springs III 403 will push the two push plates 401 into the two mold cavity holes 307, thereby pushing the aircraft wings located in the two mold cavity holes 307 forward a certain distance, thus ensuring that the aircraft can be launched and avoiding adhesion between the aircraft and the mold cavity holes 307, which would affect the launch.

[0068] like Figure 1-12 As shown:

[0069] The front end of the lower mold base 201 has a pivot shaft 601 that rotates laterally, and both ends of the pivot shaft 601 are fixed with levers 602.

[0070] After the mold is opened, the second motor, which is installed on the mold base 201, starts and drives the dial shaft 601 to rotate the two levers 602. When the crossbar 304 moves to the front end and stops, while the aircraft is still inside the two launch plates 305, the two rotating levers 602 will move the aircraft forward, thus separating the aircraft from the processing system and avoiding affecting the continued processing of the aircraft.

[0071] like Figure 13 As shown:

[0072] The method for processing a plastic toy using the aforementioned plastic toy processing system includes the following steps:

[0073] S1. The drive shaft 207 rotates, which in turn drives the lower mold base 201 to rotate on the fixed shaft 103, thus completing the mold closing.

[0074] S2. Molten plastic is injected into the aircraft cavity through injection joint 102 and allowed to cool to obtain a plastic airplane-shaped toy.

[0075] S3. The reverse drive shaft 207 rotates, causing the lower mold base 201 to rotate and separate from the upper mold base 101. During this process, the elastic force of the spring I 303 causes the roller 302 to roll on the limiting curved plate 104, thereby causing the two launch plates 305 to control the two wings of the aircraft through the two mold cavity holes 307, and separate from the lower mold base 201 and the upper mold base 101 respectively.

[0076] S4. As the lower mold base 201 continues to rotate, when the cross frame 304 rises to fit against the lower side of the lower mold base 201, it loses the limiting position of the two hook plates 205. The elastic force of the spring II 306 will push the cross frame 304 forward to slide quickly, thereby causing the two launch plates 305 to move the toy airplane. The cross frame 304 stops at the front end of the two through holes 203. The toy airplane continues to move forward due to inertia, thus flying out between the lower mold base 201 and the upper mold base 101, forming a quality test of the toy airplane.

[0077] S5. Control the lower mold base 201 to rotate, and at the same time push the push plate 501 through the electric telescopic rod 502 to reset the cross frame 304, and finally complete the mold closing, so that injection molding can be performed again.
