[0035] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of 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 more comprehensive and complete and fully convey the concept of the example embodiments to those skilled in the art.

[0036] See also 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 the present application includes: a bracket 100, an injection actuator 200, a power mechanism and an air storage box 320. The bracket 100 can be understood as a supporting structure of the injection molding machine shooting platform. The injection actuator 200 is provided with an oil cylinder, which can also be understood as a hydraulic cylinder. Under the driving action of the hydraulic oil in the hydraulic cylinder, the molten plastic in the injection actuator 200 can be pushed out.

[0038] The bracket 100 is provided with an oil tank 110 for storing hydraulic oil. The bracket 100 is generally made of metal, which can provide good support strength. Moreover, the oil tank 110 can 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.

[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 arranged 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 to the oil cylinder of the injection actuator 200, thereby driving the injection actuator 200 to perform the injection operation. When performing the 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.

[0041] The air storage tank 320 is used to store pressurized gas. The air storage tank 320 is arranged on the side of the injection actuator 200. The air storage tank 320 is connected to the oil tank 110 to provide pressurized gas to the oil tank 110. The pressurized gas stored in the air storage tank 320 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. By ventilating and pressurizing the oil tank 110 with the pressurized gas, the pressurized gas with a relatively high pressure can play a certain role in promoting the hydraulic oil in the oil tank 110. The operation of the oil pump 310 can increase the flow rate of the hydraulic oil, so that the hydraulic oil can flow to the oil cylinder faster.

[0042] In this embodiment, the oil tank 110 and the air tank 320 are separately arranged, and the oil tank 110 is arranged on the bracket 100, and the air tank 320 is arranged on the injection actuator 200, so that the structure of the oil tank 110 is reduced in the power mechanism, and the overall volume of the power mechanism is smaller. In addition, since the oil tank 110 is arranged on the bracket 100, the weight of the oil tank 110 is also reduced. The reduction in weight also makes the center of gravity of the power structure more stable, making the power unit more stable during movement, and reducing the shaking or vibration of the power unit during movement.

[0043] In addition, in the present application, the structure of the accumulator in the related art is replaced by the separate arrangement of the air tank 320 and the oil tank 110, making the structure more decentralized, making full use of the structural space, and reducing the volume of the power mechanism. Furthermore, since the air tank 320 and the oil tank 110 are separately arranged, the problem of high maintenance cost caused by high integration is avoided, and it is convenient to repair the air tank 320 or the oil tank 110 in a targeted manner, thereby reducing the repair cost.

[0044] It should be noted that the gas tank 320 is a closed box. When the injection operation is performed, the high-pressure gas in the gas tank 320 pushes the hydraulic oil in the oil tank 110 to move toward the oil pump 310, the volume of the high-pressure gas in the gas tank 320 increases, and the pressure inside the gas decreases. After the injection operation is completed, the hydraulic oil flows back into the oil tank 110, and reversely squeezes the high-pressure gas, thereby reducing the volume of the high-pressure gas and increasing the internal pressure of the high-pressure gas. It can be seen that the gas pressure of the gas tank 320 can change between high pressure and low pressure, and it can also be understood that when the internal gas pressure of the gas tank 320 changes between high and low, the gas achieves work to the outside, and the outside world does work on the gas. The gas in the gas tank 320 can release energy and absorb energy, thereby replacing the role of the accumulator in releasing energy and absorbing energy during the injection molding process of the injection molding machine.

[0045] The side of the bracket 100 may also be provided with a protrusion 101, which is symmetrically arranged on both sides of the bracket 100, and the bracket 100 can be fixed as a whole through the protrusion 101. It is convenient to fix the bracket 100 as a whole on the injection molding machine.

[0046] In the present application, the oil tank 110 is closed, and cooperates with the air storage tank 320 to form a high-pressure closed oil tank. In this way, the oil pump 310 improves the oil suction efficiency, the hydraulic oil flows faster, and the performance of the power system can be improved simultaneously.

[0047] In order to clearly explain the injection molding principle of the injection actuator 200, the following example is given: the injection actuator 200 includes a hydraulic system, a barrel, a screw, a hopper and a heater. The heater is arranged on the periphery of the barrel, the screw is arranged inside the barrel, and the hopper is generally arranged above the barrel. Plastic particles are added into the barrel through the hopper. The heater can release heat into the barrel. After the plastic particles are affected by the heat, the plastic melts and deforms to form a molten plastic. The hydraulic system pushes the screw to move. Under the pushing action of the screw, the molten plastic is squeezed out of the barrel, thereby completing the injection molding operation.

[0048] The injection actuator 200 also includes a check ring, and the working principle of the check ring is similar to that of a hydraulic check valve. When the screw rotates and plasticizes, the molten material transported from the screw groove to the screw head has a certain pressure, which pushes the check ring forward. During injection, the screw moves forward to apply pressure to the molten material at the front end, and the check ring is also moved backward by the pressure of the molten material at the front end. That is, the conical surface of the check ring fits with the cone of the screw body to form a molten backflow seal, so that the molten material at the front end of the screw head cannot flow back.

[0049] The check ring has two functions: one is to close the check ring at the beginning of the injection cycle when the thermoplastic melt is injected into the mold cavity. The other function is to open the check ring to provide a flow path for the polymer when the screw retreats and the polymer has been 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 both 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. When performing an 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 process 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 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. The motor 800 is drivingly connected to the oil pump 310. The power mechanism is a power source. The motor drives the oil pump to work. The oil pump sucks oil through the oil suction block 410 and discharges high-pressure oil from the oil outlet to the injection actuator 200. The high-pressure oil drives the injection actuator 200 to perform functional actions under the control of the valve plate.

[0052] Moreover, by setting the connection base 900, the motor 800 and the oil pump 310 can be fixed together, so that the motor 800 and the oil pump 310 form a whole, which makes the driving connection between the two more firm and reduces vibration. For example, a coupling is set between the motor 800 and the oil pump 310, one end of the coupling is connected to the motor 800, and the other end is connected to the oil pump 310. When the motor 800 is running, the oil pump 310 can be driven to run through 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 part 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, and 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 oil suction block 410 of the injection molding machine drives the hydraulic pump through the servo motor 800 to generate pressure oil, which drives the hydraulic cylinder to work, and then drives the screw to melt and inject the plastic. The design of the oil suction block 410 takes into account factors such as flow, pressure and sealing to ensure that the hydraulic system can operate stably. In addition, the oil suction block 410 is also equipped with a filtering device to prevent impurities from entering the hydraulic system and ensure the long-term stable operation of the system.

[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 oil return pipe 510 and the power pipe 520 are hard pipes with a relatively hard material, generally made of metal, such as a stainless steel pipe or a copper pipe. 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 oil return 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 flows back to the oil suction block 410 through the valve plate 420 through the oil return pipe 510, 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 left-right 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 arranged in the valve plate 420, and 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. The solenoid valve is a commonly used control element in the injection molding machine, and controls the opening and closing of the valve by turning the electromagnet on and off. For example, a direct-acting high-pressure solenoid valve, a stainless steel valve body solenoid valve, etc., these valves have the characteristics of fast response speed 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 on-off of the fluid in the injection molding machine.

[0062] A throttle valve may also be provided in the valve plate 420, and the throttle valve is used to adjust the flow rate and flow velocity of the fluid, for example, a one-way throttle valve, a hydraulic one-way valve, etc. These valves play an important role in flow control in the hydraulic system of the injection molding machine to ensure the stable operation of the system.

[0063] Since the valve plate 420 is integrated with a variety of valves, the valve plate 420 can be set in the middle area of ​​the top of the injection actuator 200 to avoid the situation where the center of gravity of the injection actuator 200 deviates due to the valve plate 420 leaning to the left or right.

[0064] In one embodiment of the present application, the injection molding machine shooting platform further includes a first hose 610 and a second hose 620; one end of the first hose 610 is connected to the air tank 320, and the other end is connected to the oil tank 110; one end of the second hose 620 is connected to the oil tank 110, and the other end is connected to the oil suction block 410. Since the injection actuator 200 can slide back and forth on the bracket 100, the relative positions of the two will change. In other words, the position between the air tank 320 and the oil tank 110, and the position between the oil pump 310 and the oil tank 110 will change. Through the connection of the hose, when the position between the injection actuator 200 and the bracket 100 changes, the air tank 320 and the oil tank 110 can still be connected to avoid gas leakage. At the same time, the connection between the oil tank 110 and the oil pump 310 can also be maintained to avoid hydraulic oil leakage. Among them, the hose can be understood as a tube with a relatively soft texture, which can withstand a certain degree of tensile deformation and remain connected. 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 the side wall of the oil tank 110 and is close to the top of the oil tank 110 , and the second hose 620 is connected to the other side wall of the oil tank 110 and is close to the bottom of the oil 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 the 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] In addition, the positions where the first hose 610 and the second hose 620 are connected to the oil tank 110 are staggered. The position where the first hose 610 is connected to the oil tank 110 is close to the front end of the oil tank 110, which is the end facing the mold, and the position where the second hose 620 is connected to the oil tank 110 is close to the rear end of the oil tank 110, which is the end facing away from the mold. In this way, the hydraulic oil in the oil tank 110 can be involved in the circulation flow as a whole.

[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 groups of sliding components 720 are provided, and the three groups of sliding components 720 are respectively provided at the front end, the middle and the rear end of the injection actuator 200. In this way, the connection positions between the injection actuator 200 and the slide rail 710 form three groups, and there are connections at the front, the middle and the rear, and the connection state is more stable, avoiding the problem of the injection actuator 200 shaking and being unstable due to the connection being concentrated at one place.

[0071] The slide rail 710 can be integrally formed and arranged on the bracket 100, or the slide rail 710 can be arranged on the bracket as a separate structure, such as by welding or rivet fixing, the slide rail 710 is fixed to the upper end of the bracket. Some hollow structures can also be made at the front end of the bracket 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 setting up two tracks, the injection actuator 200 can slide on two sets of parallel tracks, so that the left and right sides of the injection actuator 200 are constrained, reducing the problem of the injection actuator 200 shaking left and right.

[0073] For the setting of the sliding foot, a fixing part may be pre-set on the sides of the bracket 100, and the fixing part may protrude from the side of the bracket 100. One end of the sliding foot is fixed to the fixing part, and the other end of the sliding foot is slidably docked on the slide rail 710.

[0074] Furthermore, the connection base 900 can also be fixed on the injection actuator 200, so that the motor 800 is also fixed on the injection actuator 200 together with the connection 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, which reduces the failure of the injection molding machine during operation.

[0077] See also Figure 3 and Figure 4 As shown, in one embodiment of the present application, the bracket 100 and the oil tank 110 are integrally arranged, and one end of the bracket 100 is surrounded to form the oil tank 110. The bracket 100 is generally made of metal. When the bracket 100 is cast, the oil tank 110 can be manufactured simultaneously, which is more efficient, the structural strength of the oil tank 110 is also higher, and the overall structure formed by the bracket 100 and the oil tank 110 is more compact. In the present application, the oil tank 110 can be divided into two connected chambers, the upper end of the chamber is open, and a cover can be set at the opening position during subsequent assembly to form a sealed oil tank 110.

[0078] In addition, the fuel tank 110 can also be an independent structure, which can be embedded in the bracket 100 by installation, so that 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] The present application also provides an injection molding machine, which is also called an injection molding machine or an injection machine. The injection molding machine is the main molding equipment that uses a plastic molding mold to make plastic products of various shapes from thermoplastic plastics or thermosetting plastics. The injection molding machine is divided into vertical, horizontal, and all-electric types. The injection molding machine can heat the plastic, apply high pressure to the molten plastic, and make it ejected and fill the mold cavity.

[0080] In the present application, the injection molding machine includes an injection molding machine shooting platform. The injection molding machine shooting platform includes: a bracket 100, an injection actuator 200, a power mechanism and an air storage box 320. The bracket 100 is a supporting structure of the injection molding machine shooting platform. The injection actuator 200 is provided with an oil cylinder, which is a hydraulic cylinder. Under the driving action of the hydraulic oil in the hydraulic cylinder, the molten plastic in the injection actuator 200 can be pushed out.

[0081] An oil tank 110 is disposed inside 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 externally placed, and makes the overall structure more compact.

[0082] 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. When performing an injection operation, the injection actuator 200 can slide close to the mold to inject molten plastic into the mold, and after completing the injection operation, the injection actuator 200 slides away from the mold.

[0083] The power mechanism is arranged 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 to 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. The motor 800 is connected to the oil pump 310 in a driving manner. The power mechanism is a power source. The operation of the motor drives the oil pump 310 to work. The oil pump 310 sucks oil through the oil suction block 410 and discharges high-pressure oil from the oil outlet to the injection actuator 200. The high-pressure oil drives the injection actuator 200 to perform functional actions under the control of the valve plate.

[0084] The air storage tank 320 is used to store pressurized gas. The air storage tank 320 is arranged on the side of the injection actuator 200. The air storage tank 320 is connected to the oil tank 110 to provide pressurized gas to the oil tank 110. The pressurized gas stored in the air storage tank 320 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. By ventilating and pressurizing the oil tank 110 with the pressurized gas, the pressurized gas with a relatively high pressure can play a certain role in promoting the hydraulic oil in the oil tank 110. The operation of the oil pump 310 can increase the flow rate of the hydraulic oil, so that the hydraulic oil can flow to the oil cylinder faster.

[0085] The injection molding machine of this embodiment has the oil tank 110 and the air tank 320 separately arranged, and the oil tank 110 is arranged on the bracket 100, and the air tank 320 is arranged on the injection actuator 200, so that the structure of the oil tank 110 is reduced in the power mechanism, making the overall volume of the power mechanism smaller. In addition, since the oil tank 110 is arranged on the bracket 100, the weight of the oil tank 110 is also reduced. The reduction in weight also makes the center of gravity of the power structure more stable, making the power unit more stable during movement, and reducing the shaking or vibration of the power unit during movement.

[0086] The working process of the injection molding machine can be carried out in cycles. Each cycle mainly includes: quantitative feeding, melting and plasticization, pressure injection, mold filling and cooling, and mold opening and taking out the plastic parts. After taking out the plastic parts, the mold is closed again to carry out the next cycle.

[0087] The working principle of the injection molding machine can be further explained as follows: the injection molding machine heats the plastic particles 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, eventually forming the desired plastic product.

[0088] Among them, quantitative feeding is to add plastic particles into the hopper of the injection molding machine. Melt plasticization is to melt and plasticize plastic particles in the heating system of the injection molding machine. Pressure injection is to inject molten plastic into the mold under the thrust of the screw or plunger. Mold filling and cooling is to cool and solidify the plastic in the mold. Mold opening and taking out is to open the mold after cooling and take out the molded plastic product.
