[0035] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this application will be thorough and complete and will fully convey the concepts of the example embodiments to those skilled in the art.
[0036] See Figure 1 and Figure 2 As shown, the present application provides an injection molding machine shooting platform, which is mainly installed on a horizontal injection molding machine, and can also be installed on a vertical injection molding machine. The injection molding machine shooting platform mainly melts plastic particles and pushes the molten plastic into the mold.
[0037] The injection molding machine shooting platform in this application includes a bracket 100, an injection actuator 200, a power mechanism, and an air tank 320. The bracket 100 can be understood as the support structure of the injection molding machine shooting platform. The injection actuator 200 is equipped with an oil cylinder, which can also be understood as a hydraulic cylinder. The hydraulic oil in the hydraulic cylinder pushes the molten plastic in the injection actuator 200 out.
[0038] An oil tank 110 is disposed within the bracket 100 to store hydraulic oil. Bracket 100 is typically made of metal, which provides excellent support strength. Furthermore, oil tank 110 can be embedded within the bracket 100, saving space when externally located, making the overall structure more compact.
[0039] The injection actuator 200 is slidably disposed on the upper side of the bracket 100 ; the injection actuator 200 slides on the upper side of the bracket 100 , so that the injection actuator 200 can reciprocate on the bracket 100 .
[0040] The power mechanism is mounted on the side of the injection actuator 200. One end of the power mechanism is connected to the oil tank 110, and the other end is connected to the oil cylinder of the injection actuator 200. The power mechanism is used to pump hydraulic oil from the oil tank 110 into the oil cylinder of the injection actuator 200, thereby driving the injection actuator 200 to perform the injection operation. During the injection operation, the injection actuator 200 can be slid toward the mold to inject molten plastic into the mold. After the injection operation is completed, the injection actuator 200 slides away from the mold.
[0041] The air tank 320 is used to store pressurized gas. It is located on the side of the injection actuator 200 and is connected to the fuel tank 110, providing pressurized gas to the fuel tank 110. The pressurized gas stored in the air tank 320 is relatively high-pressure and is typically a stable gas, such as nitrogen or an inert gas. The pressure of the pressurized gas is greater than standard atmospheric pressure. By ventilating and pressurizing the fuel tank 110 with the pressurized gas, the higher-pressure pressurized gas can propel the hydraulic oil in the fuel tank 110 to a certain extent. This, combined with the operation of the oil pump 310, can increase the flow rate of the hydraulic oil, allowing the hydraulic oil to flow to the cylinder more quickly.
[0042] In this embodiment, the oil tank 110 and air tank 320 are separately installed, with the oil tank 110 mounted on the bracket 100 and the air tank 320 mounted on the injection actuator 200. This reduces the number of oil tanks 110 installed in the power unit, resulting in a smaller overall power unit size. Furthermore, since the oil tank 110 is mounted on the bracket 100, its weight is also reduced. This reduced weight also stabilizes the power unit's center of gravity, making the power unit more stable during movement and reducing any shaking or vibration.
[0043] Furthermore, in this application, the separate arrangement of the air tank 320 and the fuel tank 110 replaces the accumulator structure of the related art. This results in a more decentralized structure, fully utilizing the structural space and reducing the volume of the power mechanism. Furthermore, the separate arrangement of the air tank 320 and the fuel tank 110 avoids the problem of excessive maintenance costs caused by excessive integration, facilitating targeted repairs of either the air tank 320 or the fuel tank 110, thereby reducing repair costs.
[0044] It should be noted that the air tank 320 is a closed box. During the injection operation, the high-pressure gas in the air tank 320 pushes the hydraulic oil in the oil tank 110 toward the oil pump 310, increasing the volume of the high-pressure gas in the air tank 320 and reducing the pressure inside the gas. After the injection operation is completed, the hydraulic oil flows back into the oil tank 110, squeezing the high-pressure gas in the opposite direction, thereby reducing the volume of the high-pressure gas and increasing the internal pressure of the high-pressure gas. It can be seen from this that the gas pressure in the air tank 320 can vary between high and low pressures. It can also be understood that when the internal gas pressure of the air tank 320 varies between high and low, the gas performs work on the outside, and the outside world performs work on the gas. The gas in the air tank 320 can release and absorb energy, thereby replacing the role of the accumulator in releasing and absorbing energy during the injection molding process of the injection molding machine.
[0045] The sides of the bracket 100 may further be provided with raised portions 101, which are symmetrically arranged on both sides of the bracket 100. The raised portions 101 can be used to fix the entire bracket 100, making it convenient to fix the entire bracket 100 on the injection molding machine.
[0046] In this application, the oil tank 110 is closed and forms a high-pressure closed oil tank in conjunction with the air tank 320. This improves the oil suction efficiency of the oil pump 310, increases the flow rate of the hydraulic oil, and simultaneously improves the performance of the power system.
[0047] To clearly explain the injection molding principle of injection actuator 200, the following example illustrates the following: Injection actuator 200 comprises a hydraulic system, a barrel, a screw, a hopper, and a heater. The heater is located on the outer periphery of the barrel, the screw is located inside the barrel, and the hopper is generally located above the barrel. Plastic pellets are added to the barrel through the hopper. The heater releases heat into the barrel, causing the plastic pellets to melt and deform under the influence of the heat, forming molten plastic. The hydraulic system propels the screw, which pushes the molten plastic out of the barrel, completing the injection molding operation.
[0048] Injection actuator 200 also includes a check ring, which operates similarly to a hydraulic check valve. As the screw rotates and plasticizes, the molten material fed to the screw head through the screw groove exerts a certain pressure, pushing the check ring forward. During injection, the forward movement of the screw applies pressure to the molten material at the front end, and the check ring, simultaneously influenced by the pressure of the molten material, moves backward. The conical surface of the check ring mates with the cone of the screw body, forming a leak-proof seal that prevents the molten material at the front end of the screw head from flowing back.
[0049] The check ring has two functions: First, it closes at the beginning of the injection cycle, when the thermoplastic melt is injected into the mold cavity. Second, it opens to provide a flow path for the polymer when the screw retracts and the polymer has plasticized and is ready for the next injection.
[0050] In one embodiment of the present application, the power mechanism and the air tank 320 are disposed on opposite sides of the injection actuator 200. The power mechanism and the air tank 320 each have a certain weight and can be disposed on the same side of the injection actuator 200 or on both sides. When the power mechanism and the air tank 320 are disposed on both sides of the injection actuator 200, the weight of the two sides of the injection actuator 200 is more balanced, and the center of gravity of the overall structure is closer to the center of the injection actuator 200. During the injection operation, the injection actuator 200 needs to move. Since the center of gravity of the overall structure is near the center of the injection power structure, the movement of the injection actuator 200 can be made more stable, reducing the problem of the injection actuator 200 shaking back and forth and left and right.
[0051] In one embodiment of the present application, the power mechanism includes an oil pump 310, a motor 800, and a connector 900. The connector 900 is fixed to the side of the injection actuator 200. The motor 800 and the oil pump 310 are fixed to the connector 900, and the motor 800 and the oil pump 310 are connected in a driving manner. The power mechanism serves as the power source. The motor drives the oil pump, which draws oil through the oil suction block 410 and discharges high-pressure oil from the oil outlet to the injection actuator 200. Under the control of the valve plate, the high-pressure oil drives the injection actuator 200 to perform its functions.
[0052] Furthermore, by providing the connection base 900, the motor 800 and the oil pump 310 can be fixed together, forming the motor 800 and the oil pump 310 as a whole, making the drive connection between the two more secure and reducing vibration. For example, a coupling can be provided between the motor 800 and the oil pump 310, with one end of the coupling connected to the motor 800 and the other end connected to the oil pump 310. When the motor 800 is running, the oil pump 310 can be driven by the coupling.
[0053] In one embodiment of the present application, the injection molding machine shooting platform also includes an oil suction block 410 and a valve plate 420. The oil suction block 410 is arranged on the side of the injection actuator 200 and is close to the oil suction port of the oil pump 310. The oil suction block 410 is connected to the oil suction port of the oil pump 310, and the valve plate 420 is arranged at the upper end of the injection actuator 200. The oil suction block 410 is an important component of the hydraulic system of the injection molding machine. Its working principle is closely related to the overall working principle of the injection molding machine. It mainly realizes the suction and supply of hydraulic oil through the servo pump control system. The injection molding machine controls the flow of hydraulic oil through the servo pump control system, thereby realizing the injection molding of molten plastic. The oil suction block 410 ensures that the hydraulic oil can be supplied stably and efficiently through precisely designed pipes and components, thereby driving various actions of the injection molding machine.
[0054] Specifically, the injection molding machine's oil suction block 410 uses a servo motor 800 to drive a hydraulic pump, generating pressurized oil that pushes the hydraulic cylinder, which in turn drives the screw to melt and inject the plastic. The design of the oil suction block 410 takes into account factors such as flow rate, pressure, and sealing to ensure stable operation of the hydraulic system. Furthermore, the oil suction block 410 is equipped with a filter to prevent impurities from entering the hydraulic system, ensuring long-term stable operation.
[0055] The injection molding machine shooting platform also includes an oil return pipe 510 and a power pipe 520. One end of the oil return pipe 510 is connected to the oil suction block 410, and the other end is connected to the valve plate 420. One end of the power pipe 520 is connected to the oil pump 310, and the other end is connected to the valve plate 420.
[0056] The return oil pipe 510 and the power pipe 520 are hard pipes with a relatively hard material, generally made of metal, such as stainless steel pipes or copper pipes. The inner wall of the hard pipe is relatively smooth, which can reduce the resistance of the hydraulic oil in contact with it, increase the flow rate of the hydraulic oil, reduce the power loss of the hydraulic oil, and make the injection molding machine shooting platform respond faster during injection operations. The return oil pipe 510 is used to return the hydraulic oil, and the power pipe 520 is used for the oil pump 310 to transport the hydraulic oil. When the hydraulic oil is refluxed, the hydraulic oil passes through the valve plate 420 through the return oil pipe 510 and flows back to the oil suction block 410, and then enters the oil tank 110 through the oil suction block 410; when supplying oil, the oil pump 310 is running, the hydraulic oil flows to the oil suction block 410, and flows to the oil cylinder through the power pipe 520.
[0057] The valve plate 420 includes various valves for controlling the flow of hydraulic oil. When the hydraulic oil pressure decreases or the oil flow reverses, the spring of the check valve pushes the valve core to close, prohibiting the hydraulic oil from flowing in the opposite direction and preventing the oil from flowing back.
[0058] The injection actuator 200 generally includes two symmetrical oil cylinders. The valve plate 420 connects the two oil cylinders to control the delivery of hydraulic oil to the oil cylinders and the return of the hydraulic oil.
[0059] Various valves can be integrated into one structure in the valve plate 420. For example, electromagnetic reversing valves can also be provided in the valve plate 420. These electromagnetic reversing valves control the opening and closing of the liquid flow through electromagnetic action to achieve precise control.
[0060] A solenoid valve can also be provided in the valve plate 420. This solenoid valve is a commonly used control element in injection molding machines. It controls the opening and closing of the valve by switching the electromagnet on and off. Examples include direct-acting high-pressure solenoid valves and stainless steel body solenoid valves. These valves offer fast response and precise control.
[0061] A ball valve may also be provided in the valve plate 420 . The ball valve is mainly used to control the flow of fluid in the injection molding machine.
[0062] A throttle valve may also be provided in the valve plate 420 to regulate the flow rate and flow velocity of the fluid. For example, a one-way throttle valve, a hydraulic one-way valve, etc., play an important role in flow control in the hydraulic system of the injection molding machine to ensure stable operation of the system.
[0063] Since the valve plate 420 is integrated with multiple valves, the valve plate 420 can be set in the middle area of the top of the injection actuator 200 to avoid the center of gravity of the injection actuator 200 being deviated due to the valve plate 420 being tilted to the left or right.
[0064] In one embodiment of the present application, the injection molding machine's shooting platform further includes a first hose 610 and a second hose 620. The first hose 610 has one end connected to the air tank 320 and the other end connected to the oil tank 110. The second hose 620 has one end connected to the oil tank 110 and the other end connected to the oil suction block 410. Because the injection actuator 200 can slide back and forth on the bracket 100, the relative positions of the two components can change. This means that the positions of the air tank 320 and the oil tank 110, as well as the positions of the oil pump 310 and the oil tank 110, can change. The hose connection ensures that the air tank 320 and the oil tank 110 remain connected even when the position of the injection actuator 200 and the bracket 100 changes, preventing gas leakage. It also maintains the connection between the oil tank 110 and the oil pump 310, preventing hydraulic oil leakage. A hose can be understood as a relatively soft tube that can withstand a certain amount of stretching and deformation while maintaining connectivity. For example, the hose can be a rubber tube.
[0065] In order to reduce arbitrary deformation of the hose, the injection molding machine shooting platform of the present application includes a guide sleeve, which is arranged on the outer periphery of the hose. Through the setting of the guide sleeve, the hose can be well transitionally connected at the bending position between the air tank 320 and the oil tank 110, and the bending position of the hose can also be protected.
[0066] In one embodiment of the present application, the first hose 610 is connected to a side wall of the fuel tank 110 and is close to the top of the fuel tank 110 , and the second hose 620 is connected to the other side wall of the fuel tank 110 and is close to the bottom of the fuel tank 110 .
[0067] The first hose 610 is connected to the upper part of the oil tank 110 to facilitate the pressurized gas to pressurize the hydraulic oil. The second hose 620 is connected to the bottom of the oil tank 110. Under the action of high-pressure gas and the gravity of the hydraulic oil, the hydraulic oil can flow quickly from top to bottom to the second hose 620.
[0068] Furthermore, the locations where the first hose 610 and the second hose 620 connect to the oil tank 110 are staggered. The first hose 610 connects to the oil tank 110 near the front end of the oil tank 110, which faces the mold, while the second hose 620 connects to the oil tank 110 near the rear end of the oil tank 110, which faces away from the mold. This allows the entire hydraulic oil in the oil tank 110 to circulate.
[0069] In one embodiment of the present application, the injection molding machine shooting platform also includes a slide rail 710 and a sliding assembly 720. The slide rail 710 is arranged at the upper end of the bracket 100. The sliding assembly 720 is connected between the slide rail 710 and the injection actuator 200. There are multiple sliding assemblies 720, and the multiple sliding assemblies 720 are arranged at intervals in the moving direction of the injection actuator 200.
[0070] For example, three sets of sliding assemblies 720 are provided, one at the front, one in the middle, and one at the rear of the injection actuator 200. This creates three connections between the injection actuator 200 and the slide rail 710, with connections at the front, middle, and rear. This provides a more stable connection and avoids the problem of unstable injection actuator 200 caused by a single connection.
[0071] The slide rail 710 can be integrally formed with the bracket 100, or it can be provided as a separate structure on the bracket, for example, by welding or rivet fixing, and the slide rail 710 can be fixed to the upper end of the bracket. The front end of the bracket can also be hollowed out to reduce the overall weight of the bracket and reduce the amount of material used.
[0072] In one embodiment of the present application, the slide rail 710 includes a first track 711 and a second track 712, which are arranged in parallel. The sliding assembly 720 includes a first sliding foot and a second sliding foot, which are arranged on opposite sides of the injection actuator 200. The first sliding foot is slidably connected to the first track 711, and the second sliding foot is slidably connected to the second track 712. By providing two tracks, the injection actuator 200 can slide on two sets of parallel tracks. In this way, both the left and right sides of the injection actuator 200 are constrained, reducing the problem of the injection actuator 200 shaking from side to side.
[0073] For the setting of the sliding foot, a fixing portion may be pre-set on the sides of the bracket 100, and the fixing portion may protrude from the side of the bracket 100. One end of the sliding foot is fixed to the fixing portion, and the other end of the sliding foot is slidably docked on the slide rail 710.
[0074] Furthermore, the connecting base 900 can be fixed to the injection actuator 200, so that the motor 800 is also fixed to the injection actuator 200 along with the connecting base 900, so that the position of the oil pump 310 and the motor 800 remains firm, thereby reducing the vibration generated by the oil pump 310 and the motor 800 during operation.
[0075] Furthermore, the motor 800 is located at the front end of the oil pump 310, that is, the motor 800 is set at the end of the oil pump 310 facing the mold. In this way, the side position of the injection actuator 200 is fully utilized to make the overall structure of the injection machine shooting platform more compact, avoiding the situation where the structure is too dispersed and the space occupied is too large.
[0076] In one embodiment of the present application, the motor 800 and the oil pump 310 are both standard parts. As standard parts, it is easy to find replacements after a failure occurs, the cost of use is low, and the quality of standard parts is more stable, reducing the failure of the injection molding machine during operation.
[0077] See Figure 3 and Figure 4 As shown, in one embodiment of the present application, a bracket 100 and a fuel tank 110 are integrally provided, with one end of the bracket 100 surrounding the fuel tank 110. The bracket 100 is generally made of metal, and the fuel tank 110 can be fabricated simultaneously with the bracket 100 casting, resulting in higher production efficiency, greater structural strength of the fuel tank 110, and a more compact overall structure formed by the bracket 100 and the fuel tank 110. In the present application, the fuel tank 110 can be divided into two interconnected chambers, each of which is open at its upper end. During subsequent assembly, a cover can be placed at the opening to form a sealed fuel tank 110.
[0078] In addition, the fuel tank 110 can also be an independent structure that can be embedded in the bracket 100 through installation. In this way, it can be installed or removed from the bracket 100 as needed, making the assembly of the fuel tank 110 more flexible and convenient for replacement as needed. The fuel tank 110 can also be installed as an independent structure at the rear end of the bracket 100.
[0079] This application also provides an injection molding machine, also known as an injection molding machine or injection machine. An injection molding machine is the primary molding equipment used to convert thermoplastics or thermosetting plastics into plastic products of various shapes using plastic molding molds. Injection molding machines are available in vertical, horizontal, and all-electric models. They heat plastic and apply high pressure to the molten plastic, causing it to be ejected and fill the mold cavity.
[0080] In this application, the injection molding machine includes a shooting platform. The shooting platform comprises a bracket 100, an injection actuator 200, a power mechanism, and an air tank 320. The bracket 100 serves as the support structure for the shooting platform. The injection actuator 200 is equipped with a hydraulic cylinder. The hydraulic oil in the hydraulic cylinder pushes the molten plastic out of the injection actuator 200.
[0081] An oil tank 110 is provided in the bracket 100 and is used to store hydraulic oil. The oil tank 110 may be embedded in the bracket 100 , which saves the space occupied by the oil tank 110 when it is external, making the overall structure more compact.
[0082] The injection actuator 200 is slidably arranged on the upper side of the bracket 100; the injection actuator 200 slides on the upper side of the bracket 100, so that the injection actuator 200 can move back and forth on the bracket 100. When performing an injection operation, the injection actuator 200 can be slid close to the mold to inject molten plastic into the mold, and after the injection operation is completed, the injection actuator 200 slides away from the mold.
[0083] The power mechanism is located on the side of the injection actuator 200. One end of the power mechanism is connected to the oil tank 110, and the other end is connected to the oil cylinder of the injection actuator 200. The power mechanism is used to pump the hydraulic oil in the oil tank 110 into the oil cylinder of the injection actuator. The power mechanism includes an oil pump 310, a motor 800, and a connecting seat 900. The connecting seat 900 is fixed to the side of the injection actuator 200. The motor 800 and the oil pump 310 are fixed to the connecting seat 900, and the motor 800 and the oil pump 310 are connected in a driving manner. The power mechanism is the power source. The operation of the motor drives the oil pump 310, which draws oil through the oil suction block 410 and discharges high-pressure oil from the oil outlet to the injection actuator 200. Under the control of the valve plate, the high-pressure oil drives the injection actuator 200 to perform its functional actions.
[0084] The air tank 320 is used to store pressurized gas. It is located on the side of the injection actuator 200 and is connected to the fuel tank 110, providing pressurized gas to the fuel tank 110. The pressurized gas stored in the air tank 320 is relatively high-pressure and is typically a stable gas, such as nitrogen or an inert gas. The pressure of the pressurized gas is greater than standard atmospheric pressure. By ventilating and pressurizing the fuel tank 110 with the pressurized gas, the higher-pressure pressurized gas can propel the hydraulic oil in the fuel tank 110 to a certain extent. This, combined with the operation of the oil pump 310, can increase the flow rate of the hydraulic oil, allowing the hydraulic oil to flow to the cylinder more quickly.
[0085] The injection molding machine of this embodiment utilizes separate installations of the oil tank 110 and the air tank 320. The oil tank 110 is mounted on the bracket 100, while the air tank 320 is mounted on the injection actuator 200. This eliminates the need for the oil tank 110 in the power unit, reducing the overall size of the power unit. Furthermore, the placement of the oil tank 110 on the bracket 100 also reduces its weight. This reduced weight also stabilizes the power unit's center of gravity, making it more stable during movement and reducing any shaking or vibration.
[0086] The working process of the injection molding machine can be carried out in cycles. Each cycle mainly includes: quantitative feeding, melting and plasticizing, pressure injection, mold filling and cooling, and mold opening and removing the plastic parts. After removing the plastic parts, the mold is closed again and the next cycle begins.
[0087] The working principle of an injection molding machine can be further explained as follows: the injection molding machine heats plastic pellets to melt them, and then injects the molten plastic into the mold through a screw or plunger. The mold is heated and cooled in the injection molding machine, and the plastic solidifies and forms in the mold, ultimately forming the desired plastic product.
[0088] Dosing involves adding plastic pellets into the injection molding machine's hopper. Melt plasticization involves melting and plasticizing the plastic pellets in the machine's heating system. Pressure injection involves injecting the molten plastic into the mold under the thrust of a screw or plunger. Mold filling and cooling involves cooling and solidifying the plastic in the mold. Mold removal involves opening the mold after cooling and removing the molded plastic product.
