[0038] 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.

[0039] See Figures 1 to 4 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 used on a vertical injection molding machine. The injection molding machine shooting platform mainly melts the plastic particles and pushes the plastic in a molten state into the mold. The injection molding machine shooting platform of the present application includes: a bracket 100, an injection actuator 200, an oil pump 300 and a motor 400. The bracket 100 can be understood as the support structure of the injection molding machine shooting platform. An oil cylinder is provided in the injection actuator 200, and the oil cylinder can also be understood as a hydraulic cylinder. Under the pushing action of the hydraulic oil in the hydraulic cylinder, the molten plastic in the injection actuator 200 can be pushed out.

[0040] The bracket 100 is equipped with an oil tank 110 for storing hydraulic oil. The bracket 100 is generally made of metal, and the oil tank 110 is embedded in the bracket 100. This saves space when the oil tank 110 is externally located, making the overall structure more compact. Furthermore, the oil pump 300 is closer to the oil tank 110, allowing it to quickly push hydraulic oil during operation.

[0041] The injection actuator 200 includes a cylinder 210 and a melt motor 220. The melt motor 220 is slidably mounted on the upper side of the bracket. The cylinder 210 is fixed to the upper side of the bracket and located at the front end of the melt motor 220. The melt motor 220 drives the screw to rotate. The rotation of the screw draws solid plastic from the hopper into the barrel. The plastic is gradually heated through the shearing and friction effects of the screw.

[0042] The oil pump 300 is embedded in the oil tank 110 and connected to the oil cylinder 210 of the injection actuator 200. The motor 400 is positioned corresponding to the oil pump 300 and is in driving connection with the oil pump 300. The oil pump 300 operates within the oil tank 110, generating high-pressure oil that pushes the oil cylinder 210 of the injection actuator 200 to perform the injection operation. During the injection operation, the motor 400 drives the oil pump 300, which delivers hydraulic oil to the oil cylinder 210 of the hydraulic system.

[0043] The oil pump 300 and motor 400 form a power mechanism. During injection, the power mechanism serves as the power source. The motor 400 drives the oil pump 300, which draws oil from the oil tank 110 through the oil intake 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 function.

[0044] In this embodiment, the oil pump 300 is arranged in the oil tank 110, and hydraulic oil is stored in the oil tank 110. The vibration generated by the oil pump 300 during operation will be transmitted to the hydraulic oil, and the vibration will drive the hydraulic oil to vibrate. However, in this process, the mechanical vibration will be converted into liquid vibration, consuming the energy generated by the oil pump 300 to generate vibration. In other words, the hydraulic oil can absorb the vibration generated by the oil pump 300, so that the vibration of the oil pump 300 is difficult to be transmitted to the outside, thereby reducing the vibration of the external mechanical structure and the vibration of the external air. Thereby, the generation of noise is reduced, making the injection molding machine of the present application quieter. Moreover, since the vibration of the injection molding machine itself is reduced, the vibration of the connection positions of each component is also reduced synchronously, the stability of the connection is higher, and the situation of the connection positions of the components being detached is reduced.

[0045] In addition, the motor and oil pump in this application are standard parts, and 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.

[0046] To clearly understand the injection molding principle of injection actuator 200, the following example illustrates that injection actuator 200 also includes 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, and the plastic pellets, affected by the heat, melt and deform, forming molten plastic. The hydraulic system drives the screw, and under the propulsion of the screw, the molten plastic is squeezed out of the barrel, completing the injection molding operation.

[0047] 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.

[0048] 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.

[0049] The fuel tank 110 is mounted at one end of the bracket 100, with the motor 400 facing the fuel tank 110. This direct alignment of the motor 400 with the fuel tank 110 allows it to connect to the fuel pump 300 within the tank 110. Furthermore, the motor 400 is also fixed to one end of the bracket 100, allowing it to move synchronously with the movement of the bracket 100. The other end of the bracket 100 can be hollowed out to reduce its overall weight.

[0050] In one embodiment of the present application, the injection molding machine shooting platform further includes a connector 500 and a coupling 600. The connector 500 is disposed between the oil pump 300 and the motor 400. The coupling 600 is disposed through the connector 500, with one end of the coupling 600 connected to the oil pump 300 and the other end connected to the motor 400. The coupling 600, also known as a coupling, is used to securely connect the motor 400 and the oil pump 300 so that they can operate together. In other words, the coupling 600 can drive the oil pump 300 and the motor 400 together, and when the motor 400 is in operation, the driving force can be transmitted to the oil pump 300 through the coupling 600.

[0051] Furthermore, connector 500 effectively secures motor 400, securing motor 400 to one end of bracket 100, maintaining the relative position between motor 400 and bracket 100 and enhancing the securement of motor 400 within bracket 100. When coupling 600 passes through connector 500, connector 500 provides some support for coupling 600. Connector 500 also protects the periphery of coupling 600, reducing damage to coupling 600 from external forces and thus providing a certain degree of protection for coupling 600.

[0052] In one embodiment of the present application, the connector 500 and the bracket 100 are arranged to form an oil tank 110, and a space 111 is formed between the oil pump 300 and the inner wall surface of the oil tank 110. The space 111 is used to fill hydraulic oil. The coupling 600 can pass through the connector 500 and be connected to the oil pump 300. It can be seen that one end of the oil pump 300 is connected to the coupling 600, and the rest of the oil pump 300 is suspended in the air. The oil pump 300 and the inner wall surface of the oil tank 110 are separated by a certain distance, that is, the space 111 is formed. Hydraulic oil is stored in the oil tank 110, and the hydraulic oil is filled in the space 111. In this way, the oil pump 300 is basically wrapped by the hydraulic oil. When the oil pump 300 vibrates during operation, the hydraulic oil can absorb the vibration energy very well.

[0053] As can be seen from the above, part of the structure of the oil tank 110 is completed simultaneously when the bracket 100 is processed, that is, when the bracket 100 is cast, part of the structure of the oil tank 110 is formed integrally.

[0054] In addition, the fuel tank 110 can also be an independent structure, which can be embedded in the bracket 100 by installation, and can also be removed from the bracket 100 as needed. In this way, the assembly of the fuel tank 110 is more flexible and easy to replace as needed.

[0055] See Figures 4 to 7 As shown, in one embodiment of the present application, the connector 500 includes a first connecting plate 510, a second connecting plate 520, and a fixing member 530. The bracket 100 forms a cavity with an open end. The first connecting plate 510 is sealed at the cavity opening of the bracket 100 to form an oil tank 110. The first connecting plate 510 is connected to the bracket 100 to form the oil tank 110. When installing the first connecting plate 510, the oil pump 300 and the coupling 600 can be installed on the first connecting plate 510 first.

[0056] Furthermore, to ensure more balanced vibration absorption by the hydraulic oil, the coupling 600 can be passed through the center of the first connecting plate 510. This allows the oil pump 300 to be positioned approximately in the center of the oil tank 110, with the distance between the oil pump 300 and the inner wall of the oil tank 110 being substantially equal. This allows the hydraulic oil to more evenly absorb vibrations from the oil pump 300. After installing the coupling 600 and the first connecting plate 510, connect the oil pump 300 to the passed coupling 600, and then dock the first connecting plate 510 with the oil pump 300 at the opening of the cavity of the bracket 100.

[0057] The second connecting plate 520 is connected to the motor 400, and the fixing member 530 is fixed between the first connecting plate 510 and the second connecting plate 520. The coupling 600 is passed through the first connecting plate 510 and the second connecting plate 520. The first connecting plate 510 and the second connecting plate 520 are spaced apart to form the working opening 501. The fixing member 530 is disposed between the first connecting plate 510 and the second connecting plate 520. It can be considered that the fixing member 530, the first connecting plate 510 and the second connecting plate 520 are integrally arranged. It can also be considered that the first connecting plate 510, the second connecting plate 520 and the fixing member 530 are relatively independent, and the first connecting plate 510 and the second connecting plate 520 are fixed together by the connection of the fixing member 530.

[0058] During installation, the motor 400 can be pre-installed at the second connecting plate 520, with the coupling 600 also passing through the second connecting plate 520. The motor 400 is then connected to the location where the coupling 600 passes through the second connecting plate 520. When docking with the bracket 100 for installation, the entire structure including the motor 400, the connector 500, and the oil pump 300 can be docked to the bracket 100 to improve installation efficiency.

[0059] In addition, the injection molding machine shooting platform also includes fasteners. When the first connecting plate 510 is docked with the bracket 100, the fasteners are inserted into the first connecting plate 510 and the bracket 100 to fix the first connecting plate 510 and the bracket 100 together. The working opening facilitates the application of force to the fastener. For example, if the fastener is a screw, the working opening 501 facilitates the application of torsional force, thereby rotating the screw so that the screw is tightly fixed to the first connecting plate 510. Generally, four fasteners are provided, with one fastener provided at each of the four corners of the first connecting plate 510. Of course, the number of fasteners can also be greater, such as five or six.

[0060] Furthermore, the injection molding machine shooting platform may further include a sealing ring, which may be made of rubber and is disposed between the first connecting plate 510 and the bracket 100. Generally, the first connecting plate 510 and the bracket 100 have relatively rigid structures, and their connection is prone to poor sealing. The provision of the sealing ring can reduce the gap between the first connecting plate 510 and the bracket 100, thereby improving the sealing effect between the first connecting plate 510 and the bracket 100.

[0061] In one embodiment of the present application, the injection molding machine shooting platform also includes an air tank 710, which is used to store pressurized gas. The air tank 710 is arranged on the bracket 100 or the injection actuator 200, and the air tank 710 is connected to the oil tank 110. The pressurized gas stored in the air tank 710 has a relatively high pressure and is a high-pressure gas. The pressurized gas is generally a gas with stable performance, such as nitrogen or an inert gas. The pressure of the pressurized gas is greater than the standard atmospheric pressure. The oil tank 110 is ventilated by the pressurized gas. The high-pressure pressurized gas can play a certain role in promoting the hydraulic oil in the oil tank 110. In conjunction with the action of the oil pump 300, the flow rate of the hydraulic oil can be increased, so that the hydraulic oil can flow to the oil cylinder 210 faster. In addition, it can be seen that the air tank 710 can be arranged on the bracket 100 or on the injection actuator 200.

[0062] In the related art, the provision of the accumulator results in a large volume, high weight, high integration, and inconvenient maintenance for the entire injection molding structure. Furthermore, it leads to inconvenient installation, excessive volume, unstable center of gravity, loose fixation, and the entire power unit being prone to shaking or vibrating. In the present application, the accumulator structure in the related art is replaced by the provision of an air tank 710 and an oil tank 110. This makes the structure more dispersed, fully utilizes the structural space, and reduces the volume of the injection molding power unit. Separating the air tank 710 and the oil tank 110 reduces the weight of the power unit, thereby reducing shaking. Furthermore, separate provision also avoids excessive integration, facilitates targeted repairs, and reduces repair costs.

[0063] The fuel tank is connected to the air tank and built into the bracket to form a high-pressure closed fuel tank. This improves the oil pump's oil suction efficiency and also improves the performance of the power system.

[0064] In one embodiment of the present application, an air tank 710 is mounted on a bracket 100, and the injection molding machine's shooting platform further includes a hose 720. The air tank 710 has a first connection hole, and a second connection hole is provided on a sidewall of the bracket 100. The second connection hole corresponds to and communicates with the fuel tank 110. One end of the hose 720 is connected to the first connection hole, and the other end is connected to the second connection hole. Through the connection of the hose 720, pressurized gas can be delivered to the fuel tank 110.

[0065] The arrangement of the hose 720 facilitates connection and installation. The hose 720 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 720 can be a rubber tube.

[0066] To reduce any deformation of the hose 720, the injection molding machine's shooting platform includes a guide sleeve 730. The guide sleeve 730 is positioned around the outer periphery of the hose 720, extending parallel to the direction of movement of the melt motor 220. Furthermore, the guide sleeve 730 is positioned between the oil tank 110 and the air tank 710. The provision of the guide sleeve 730 allows the hose 720 to smoothly extend between the air tank 710 and the oil tank 110, reducing any twisting or snaking of the hose 720.

[0067] Of course, in this application, a hard pipe can also be used to connect between the air storage tank 710 and the oil tank 110.

[0068] In one embodiment of the present application, the injection molding machine shooting platform further includes a valve plate 800, which is disposed on the injection actuator 200; the injection molding machine shooting platform further includes a power pipe 810 and an oil return pipe 820. One end of the power pipe 810 passes through the side wall of the bracket 100 and is connected to the oil pump 300, and the other end is connected to the valve plate 800. One end of the oil return pipe 820 is connected to the oil tank 110, and the other end is connected to the valve plate 800. The hydraulic oil pumped by the oil pump 300 is output to the valve plate 800 through the power pipe 810. When returning the oil, the hydraulic oil flows back from the valve plate 800 to the oil tank 110 through the oil return pipe 820.

[0069] Both the power pipe 810 and the oil return pipe 820 are rigid pipes made of a relatively hard metal, such as stainless steel or copper. The relatively smooth inner wall of the rigid pipe reduces the resistance of the hydraulic oil to the pipe, increasing the flow rate of the hydraulic oil and reducing power loss. This allows the injection molding machine's shooting platform to respond more quickly during injection operations.

[0070] In one embodiment of the present application, the valve plate 800 and the air tank 710 are arranged on opposite sides of the injection actuator 200. Various valves are installed on the valve plate 800, and precise control of the hydraulic oil is achieved through the valves. The material of the air tank 710 is generally metal, but it can also be a composite material with higher strength to ensure that the air tank 710 can withstand a certain gas pressure. The valve plate 800 and the air tank 710 both have a certain weight. By setting the valve plate 800 and the air tank 710 separately, the left and right weights of the injection molding machine shooting platform can be balanced, making the center of gravity of the injection molding machine shooting platform more stable. Moreover, setting the valve plate 800 and the air tank 710 separately on both sides can also make the overall structure more concise.

[0071] The valve plate 800 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.

[0072] The injection actuator 200 generally includes two left-right symmetrical oil cylinders 210 . The valve plate 800 connects the two oil cylinders 210 to control the delivery of hydraulic oil to the oil cylinders 210 and to control the return flow of the hydraulic oil.

[0073] Various valves can be integrated into one structure in the valve plate 800. For example, electromagnetic reversing valves can be provided in the valve plate 800, and these electromagnetic reversing valves control the opening and closing of the liquid flow through electromagnetic action to achieve precise control.

[0074] A solenoid valve can also be installed in the valve plate 800. Solenoid valves are commonly used control components in injection molding machines. They control the opening and closing of the valve by turning the electromagnet on and off. For example, direct-acting high-pressure solenoid valves and stainless steel body solenoid valves are available. These valves have the characteristics of fast response and precise control.

[0075] A ball valve may also be provided in the valve plate 800 . The ball valve is mainly used to control the flow of fluid in the injection molding machine.

[0076] A throttle valve may also be provided in the valve plate 800 to regulate the flow rate and velocity of the fluid. For example, a one-way throttle valve or a hydraulic one-way valve may be provided. These valves play an important role in flow control in the hydraulic system of the injection molding machine, ensuring stable operation of the system.

[0077] In one embodiment of the present application, the injection molding machine shooting platform further includes a slide 900 and a first slide rail 910; the bracket 100 is disposed above the first slide rail 910, and at least four slides 900 are provided, with the four slides 900 being disposed around the bracket 100 and slidably connected to the first slide rail 910; the slides 900 can be fixed around the bracket 100, and the connection between the slides 900 and the first slide rail 910 enables the bracket 100 to slide on the first slide rail 910. The provision of four slides 900 makes the contact position between the bracket 100 and the first slide rail 910 more balanced, reducing the problem of the bracket 100 shaking left and right.

[0078] The sliding foot 900 can be provided with fixing portions 120 pre-installed on the four sides of the bracket 100. The four fixing portions 120 are symmetrically arranged and protrude from the four sides of the bracket 100. One end of the sliding foot 900 is fixed to the fixing portion 120, and the other end of the sliding foot 900 is slidably docked on the first slide rail 910.

[0079] The injection molding machine's shooting platform also includes a second slide rail 920, which is disposed on the upper side of the bracket 100. The melt motor 220 is disposed on the second slide rail 920. Multiple sliding connection points can be provided between the melt motor 220 and the second slide rail 920, and the positions of the sliding connection points can also be evenly distributed to ensure stable sliding of the melt motor 220 relative to the second slide rail 920.

[0080] 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.

[0081] In this application, an injection molding machine includes an injection molding machine station. The operating process of an injection molding machine can be carried out in cycles. Each cycle mainly includes: quantitative feeding, melt plasticization, pressure injection, mold filling and cooling, and mold opening and part removal. After removing the plastic part, the mold is closed again to start the next cycle.

[0082] 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.

[0083] 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.

[0084] The injection molding machine's shooting platform is primarily installed on a horizontal injection molding machine. The injection molding machine's shooting platform comprises a bracket 100, an injection actuator 200, an oil pump 300, and a motor 400. The bracket 100 serves as the support structure for the injection molding machine's shooting platform. The injection actuator 200 comprises an oil cylinder 210 and a melt motor 220. The melt motor 220 is slidably mounted on the upper side of the bracket. The oil cylinder 210 is fixed to the upper side of the bracket and located at the front end of the melt motor 220. The oil cylinder 210 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. An oil tank 110 is located within the bracket 100 to store the hydraulic oil. The bracket 100 is generally made of metal, and the oil tank 110 is essentially embedded within the bracket 100. This saves space when the oil tank 110 is externally mounted, making the overall structure more compact.

[0085] The melt motor 220 is slidably mounted on the upper side of the bracket 100, enabling movement. The oil pump 300 is embedded within the oil tank 110 and connected to the oil cylinder 210 of the injection actuator 200. The motor 400 is positioned corresponding to the oil pump 300 and is in driving connection with the oil pump 300. The oil pump 300 operates within the oil tank 110, pushing the oil cylinder 210 of the injection actuator 200 to perform the injection operation. During the injection operation, the motor 400 drives the oil pump 300, which delivers hydraulic oil to the oil cylinder 210 of the hydraulic system.

[0086] In the injection molding machine of this embodiment, the oil pump 300 is disposed in the oil tank 110, and the oil tank 110 stores hydraulic oil. The vibration generated by the oil pump 300 during operation will be transmitted to the hydraulic oil, and the vibration will drive the hydraulic oil to vibrate. However, in this process, the mechanical vibration will be converted into liquid vibration, consuming the energy generated by the vibration of the oil pump 300. In other words, the hydraulic oil can absorb the vibration generated by the oil pump 300, making it difficult for the vibration of the oil pump 300 to be transmitted to the outside, thereby reducing the vibration of the external mechanical structure and the vibration of the external air, thereby reducing the generation of noise.
