Description

Technical Field

[0001] The invention relates to the technical field of injection molding machines, in particular to a high-efficiency injection molding machine. Background Art

[0002] Injection molding machine is the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting materials. Its working principle is similar to that of a syringe used for injections. With the help of the thrust of the screw, the plasticized molten plastic is injected into the closed mold cavity, and the product is obtained after solidification and shaping.

[0003] Traditional injection molding machines demould the mold after the plastic in the mold has completely cooled and formed. At this time, the plastic inside the mold is still connected to the plastic in the injection port. When demoulding is performed, the plastic in the middle solid-liquid mixed part is pulled apart and separated. At this time, the liquid plastic will produce plastic wire drawing and fall inside the mold, forming defects on the surface of the next injection molded product, reducing product quality. At the same time, the continued filling of the mold cavity will also be affected. If the plastic wire drawing is large, it will affect the subsequent injection of plastic, resulting in consequences such as glue leakage and difficulty in demolding. Summary of the invention

[0020] Compared with the prior art, the advantages of the present invention are:

[0021] 1. In the present application, before the plastic is completely cooled and shaped, the shear force brought by the rotation is used to split the plastic, and the demolding work is performed after it is completely cooled, thereby avoiding the influence of plastic drawing. At the same time, the rotation of the driven wheel is used to separate the injection molding, cooling, and demolding steps, so that these steps are carried out simultaneously in the four groups of molds behind the turntable-shaped driven wheel, thereby maximizing the working efficiency of the injection molding machine.

[0022] 2. In the present application, by setting up a liquid cooler, a cross rotary joint, a spiral tube and heat dissipation fins, the heat in the first mold can be quickly and fully transferred to the coolant inside the spiral tube, and then transferred to the heat dissipation fins and the heat spreader, so that the heat dissipation of the first mold can be quickly achieved, so that the injection molded parts inside it can be quickly cooled.

[0023] 3. The ultrasonic waves released by the ultrasonic rod in this application can cause the liquid in the spiral tube to vibrate slightly. This vibration can prevent the bubbles in the liquid from adhering to the tube wall, reduce thermal resistance, and increase the efficiency of heat transfer from the spiral tube to the cooling fins. At the same time, it can cause the cooling fins to produce high-frequency slight vibrations. This vibration can destroy the air boundary layer on the surface of the cooling fins, significantly improve the heat exchange coefficient of the surrounding air, and further enhance the heat dissipation effect.

[0024] 4. In the present application, by setting the wave spring, when the second mold and the first mold are separated, the sheet structure of the wave spring has a larger surface area, thereby increasing the contact area with the circular plate, and playing a role in assisting the heat dissipation of the second mold. The holes on the sheet surface of the wave spring promote air circulation during the compression and relaxation process, which can further promote heat loss, accelerate the demolding process and improve injection molding efficiency.

[0025] To summarize, the present application utilizes the shear force brought by rotation to split the plastic through the setting of the above-mentioned structure, thereby avoiding the influence of plastic drawing. At the same time, it relies on the separation of injection molding, cooling, and demolding work steps to maximize the working efficiency of the injection molding machine, and can also make the injection molded parts cool quickly, accelerate the demolding process to improve the injection molding efficiency.

The housing 10 is partially hollowed out, and a driven wheel 21 is arranged on the side of the housing 10 close to the barrel 12. A motor 18 is fixedly mounted on the upper side of the inside of the equipment box 3. The output end of the motor 18 is keyed to a rotating rod 19, and the end of the rotating rod 19 away from the motor 18 is fixedly connected to a driving wheel 20. The driving wheel 20 is meshed and connected with the driven wheel 21, so that when the motor 18 is running, the driving wheel 20 can be driven to rotate by driving the rotating rod 19, thereby driving the driven wheel 21 to rotate. A plurality of obliquely arranged openings are provided at equal angles on the driven wheel 21, the left end of the opening is close to the center of the circle, and the right end is away from the center of the circle. The sharp mouth at the left end of the barrel 12 corresponds to the position of the opening and fits with it, so that the heated and melted material can enter the opening through the sharp mouth.

[0041] The output end of the liquid cooler 2 is connected to a water outlet pipe 22, which is made of hard material and has a certain supporting capacity. When it rotates and passes through the center of the driven wheel 21, it can start a certain supporting effect on the driven wheel 21. A first partition 31 is arranged on the left side of the driven wheel 21, and a plurality of spiral tubes 24 are fixedly installed at equal angles between the first partition 31 and the driven wheel 21. The number of spiral tubes 24 is the same as the number of holes on the driven wheel 21.

The straight edge on the left side of the hole is blade-shaped and continuously transitions to the right side to be a complete circle. A second mold 28 is slidably installed on the inner side of the first mold 27, and a molding cavity is formed between the second mold 28 and the first mold 27. A circular plate 30 is fixedly installed on the left end of the second mold 28, and a circular groove for installing the circular plate 30 is provided on the first partition plate 31.

[0043] A support 35 fixedly mounted on the operating table 4 is provided on the left side of the first partition 31, and a rotating telescopic device 34 is fixedly mounted on the support 35. The rotating telescopic device 34 is a prior art and its specific structural design is not described in detail here. The right end of the rotating telescopic device 34 is rotatably mounted with the second partition 33, and a plurality of groups of ultrasonic rods 29 are fixedly mounted on the working end of the rotating telescopic device 34. The end of the ultrasonic rod 29 away from the rotating telescopic device 34 is inserted into the inner side of the second mold 28 after rotating through the second partition 33, so that when the rotating telescopic device 34 is running, the second mold 28 can be driven to rotate by the ultrasonic rod 29, and an ejection device is installed on the right end of the ultrasonic rod 29. The ejection device is a prior art and its specific structural design is not described in detail here. Through the setting of the ejection device, during the demolding process, pressure can be applied to the injection molded part wrapped on the outside of the second mold 28, thereby facilitating its demolding.

[0044] A wave spring 32 is provided between the circular plate 30 and the second partition plate 33 and is sleeved on the outside of the ultrasonic rod 29. One end of the wave spring 32 is fixedly connected to the second partition plate 33, and the other end is rotatably connected to the circular plate 30. The sheet structure of the wave spring 32 has a large surface area, which can increase the contact area with the circular plate 30 and assist the heat dissipation of the second mold 28. At the same time, the holes on the sheet surface of the wave spring 32 promote air circulation during the compression and relaxation process, which can further promote the loss of heat, accelerate the demolding process and improve the injection molding efficiency.

[0045] The input end of the liquid cooler 2 is connected to a water inlet pipe 36. The end of the water inlet pipe 36 away from the liquid cooler 2 is connected to the cross rotary joint 23 at the output end of the spiral tube 24 after passing through the rotating telescopic device 34 and the first partition 31, so that the coolant can circulate and cool in the device, thereby achieving sufficient heat dissipation of the device.

[0046] A waste box 8 installed inside the operating table 4 is arranged below between the driven wheel 21 and the barrel 12, and a first box door 6 is rotatably installed on one side of the waste box 8. By opening the first box door 6, the waste temporarily stored in the waste box 8 can be taken out, and a finished product box 9 installed inside the operating table 4 is arranged between the first partition plate 31 and the second partition plate 33, and a second box door 7 is rotatably installed on one side of the finished product box 9.

[0047] The specific working principle of the present invention is as follows: the equipment is turned on through the control box 1, and the raw material particles are added into the barrel 12 from the injection port 11. The injection port 11 and the barrel 12 are connected by a fixed ring 13. The fixed ring 13 has a heating function to increase the initial temperature of the raw material to facilitate the melting and mixing of the raw material particles in subsequent operations. The barrel 12 is fixed on the top of the equipment box 3 through a barrel bracket 16. The outer surface of the barrel 12 is provided with a plurality of heating rings 14 arranged laterally and connected to the wire tube 15. A spiral conveying rod 17 is provided in the barrel 12, which can effectively mix the raw materials and realize stable and continuous material transportation.

[0048] The molten plastic is squeezed into the oblique opening of the driven wheel 21 from the pointed mouth at the left end of the barrel 12, and the molten plastic enters between the first mold 27 and the second mold 28 through the opening on the driven wheel 21 and the through hole on the first mold 27. The right side of the second mold 28 forms a complete and flush surface with the right side of the ultrasonic rod 29. The cavitation effect and mechanical effect generated by the ultrasonic wave in the molten plastic will reduce the entanglement between the polymer molecular chains, reduce the viscosity of the molten plastic, significantly improve the fluidity of the plastic, make the molten plastic more evenly distributed in the mold cavity, reduce welding marks and cheongsam dents, effectively improve the tensile strength, bending strength and impact strength of the injection molded parts, and also facilitate the demolding of the injection molded parts.

[0049] When the molten plastic completely fills the gap between the first mold 27 and the second mold 28, the motor 18 drives the driving wheel 20 to rotate counterclockwise by ninety degrees through the rotating rod 19, and the driven wheel 21 rotates clockwise by ninety degrees under the drive of the driving wheel 20. At this time, the part where the plastic injection is completed is located above the device for cooling. Through the rotation of the driving wheel 20, the molten plastic between the first mold 27, the second mold 28 and the barrel 12 is cut and separated, and the shear force brought by the rotation is used to divide the plastic. After it is completely cooled, the demolding work is carried out to avoid the influence of plastic drawing. At the same time, the rotation of the driven wheel 21 is used to realize the separation of the injection molding, cooling and demolding work steps, so that these steps are carried out simultaneously in the four groups of molds behind the turntable-shaped driven wheel 21, thereby maximizing the working efficiency of the injection molding machine.

[0050] At the same time, the cooling work is carried out synchronously. The water outlet pipe 22 connected to the liquid cooler 2 transports the coolant to the cross rotary joint 23 and guides it to the four groups of spiral tubes 24 respectively. The spiral tubes 24 pass through the tilted heat sink fins 26. The heat sink fins 26 are connected to the heat spreader 25, which can further increase the surface area of ​​heat dissipation and enhance the heat dissipation effect, so that the heat can be evenly and quickly transferred from the multiple spiral tubes 24 to the heat sink fins 26. The holes on the heat sink fins 26 and the rotation of the driven wheel 21 help to guide the natural convection of the air, allowing the air to flow between different levels to form a more complex and effective convection pattern, thereby continuously taking away the heat. At the same time, the ultrasonic wave released by the ultrasonic rod 29 can make the liquid in the spiral tube 24 vibrate slightly. This vibration can prevent the bubbles in the liquid from adhering to the tube wall, reduce thermal resistance, and increase the efficiency of heat transfer from the spiral tube 24 to the heat sink fins 26. At the same time, it can make the heat sink fins 26 produce high-frequency slight vibrations. This vibration can destroy the air boundary layer on the surface of the heat sink fins 26, significantly improve the heat exchange coefficient of the surrounding air, and further enhance the heat dissipation effect.

[0051] After the injection molded part above has finished cooling, the driven wheel 21 continues to rotate ninety degrees clockwise, and then the ultrasonic rod 29 is rotated by the rotating telescopic device 34. The ultrasonic rod 29 drives the circular plate 30, the second mold 28 and the first mold 27 to rotate. The hole on the right side of the first mold 27 is not a conventional cylindrical hole. The left end of the through hole on the first mold 27 is semicircular, and the right end is a complete circle. The straight edge on the left side of the hole is blade-shaped and continuously transitions to the right side to become a complete circle. When the first mold 27 rotates, the right-angled edge on the left side of the hole is used to cut the gate of the injection molded part. Since the hole in the driven wheel 21 is inclined, the plastic solidified inside it is also inclined, which plays a fixing role. During the cutting process, due to the inclination of the cutting blade, the plastic strip inside the driven wheel 21 will also be displaced outward and fall off, and fall into the waste box 8 inside the operating table 4 for collection.

[0052] After the ultrasonic rod 29 completes the rotation, the contraction of the ultrasonic rod 29 is used to drive the second mold 28 to move to the left, and the first partition plate 31 and the circular plate 30 move to the left to compress the wave spring 32, so that the second mold 28 and the first mold 27 are separated. The sheet structure of the wave spring 32 has a large surface area and can increase the contact area with the circular plate 30 at the same time, thereby assisting the second mold 28 in dissipating heat. The holes on the sheet surface of the wave spring 32 promote air circulation during the compression and relaxation process, which can further promote the loss of heat, accelerate the demolding process and improve the injection molding efficiency.

[0053] Continue to rotate the driven wheel 21 ninety degrees. At this time, the injection molded part is located below the device. At this time, the injection molded part is wrapped on the second mold 28. By installing an ejection device on the rightmost end of the ultrasonic rod 29, the injection molded part is pushed to the right and then falls into the finished product box 9 inside the operating table 4. The ejection device contracts to merge the second mold 28 with the first mold 27. If the plastic strip in the previous step has not fallen, at this time, due to the inclined hole of the driven wheel 21 facing downward, due to the gravity factor and the compression of the air between the two when the molds are closed, an air flow impulse will be generated to rush the plastic strip out and make it fall into the waste box 8.

[0054] After completing the above work, the driven wheel 21 is rotated clockwise by 90 degrees again to return to its initial state, and the next round of injection molding is started. When the plastic parts in the waste box 8 and the finished product box 9 are filled, the first box door 6 and the second box door 7 are opened to take out the materials inside the two.

[0055] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
