Description

Technical Field

[0001] This invention relates to the field of injection molding equipment technology, specifically to a template sliding mechanism for an injection molding machine. Background Technology

[0002] An injection molding machine is a device that melts thermoplastic or thermosetting materials by heating and injects them into a mold. After cooling and solidification, the desired plastic product is obtained. Injection molding machines are widely used in the plastics processing industry and are widely applied in many fields such as packaging, electronics, automobiles, home appliances, and medical devices.

[0003] Large and medium-sized injection molding machines require hydraulic support sliding foot systems for the moving template. Generally, multiple sets of sliding feet are used for equal pressure support to minimize the bending moment of the moving template on the tie rod, ensuring that the tie rod is always in a horizontal state and improving the working performance of the mold closing components.

[0004] Since the hydraulic support force is usually set at the factory based on the average weight of the mold, when the mold weight changes significantly, the hydraulic support force needs to be manually adjusted. Most sliding foot mechanisms can only be adjusted manually by adjusting the pressure relay, rather than by inputting the pressure value through the control panel. This is very inconvenient. Moreover, when the sliding foot slides back and forth on the slide rail, the friction between the sliding foot and the slide rail will generate metal shavings. The accumulation of metal shavings on the slide rail can easily cause further wear and scratches on the sliding foot and the slide rail, leading to increased friction between the sliding foot and the slide rail. This prevents the sliding foot and the slide rail from moving smoothly, affecting the movement of the moving mold plate. Consequently, the injection molding machine cannot quickly complete the mold closing and opening operations during production, affecting the production efficiency of the injection molding machine.

[0005] Combining the above issues, we find that the existing injection molding machine template sliding mechanism on the market is difficult to avoid the problems mentioned above when in use. Even if it can be solved, it requires the use of external tools, thus failing to achieve the desired effect. Therefore, we propose an injection molding machine template sliding mechanism. Summary of the Invention

[0006] The purpose of this invention is to provide a sliding foot mechanism for injection molding machine templates to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a sliding foot mechanism for an injection molding machine template, comprising a movable template, four tie rods slidably connected to the inner wall of the movable template, four plunger cylinders fixedly installed at the bottom of the movable template, a bearing plate fixedly installed at the output end of the plunger cylinders, a sliding plate slidably connected to the surface of the bearing plate, a slide rail provided at the bottom of the movable template, the surface of the sliding plate slidably connected to the surface of the slide rail, and a cleaning and lubrication mechanism provided at the bottom of the movable template; The cleaning and lubrication mechanism includes a cleaning unit, which is used to clean metal debris generated by sliding friction on the slide rail. The cleaning and lubrication mechanism also includes a lubrication unit, which works in conjunction with the cleaning unit to lubricate the slide plate as it moves on the slide rail. A lifting mechanism is provided on one side of the movable template. The lifting mechanism is used to support the movable template, which can reduce the bending moment of the movable template on the tie rod to a minimum and ensure that the tie rod is always in a horizontal state.

[0008] Preferably, the cleaning unit includes a tension spring, one end of which is fixedly installed at the bottom of the movable template. There are two tension springs. One end of each tension spring is fixedly installed with a fixing frame. A rotating shaft is rotatably connected to the inner wall of the fixing frame. A roller is fixedly installed on the surface of the rotating shaft. The surface of the roller is slidably connected to the surface of the slide rail. A drum is fixedly installed at one end of the rotating shaft. A number of rubber strips are fixedly installed on the surface of the drum. The rubber strips are arranged in a spiral shape.

[0009] By setting rollers, when the moving template moves into and out of the mold, it drives the rollers to roll on the slide rail. When the rollers rotate, they drive the rotating shaft to rotate on the inner wall of the fixed frame, which in turn drives the roller to rotate. The roller drives the rubber strip to rotate, thereby cleaning the metal debris generated by friction on the slide rail. By setting the spirally arranged rubber strips, the cleaned metal debris can be transported to one side of the slide rail, thus avoiding a large accumulation of metal debris on the slide rail and maintaining smooth movement between the slide plate and the slide rail. The reaction force of the tension spring can increase the force of the rollers on the slide rail, thereby increasing the power output of the rollers to the roller and improving the cleaning effect of the rubber strips on the slide rail.

[0010] Preferably, the roller is made of rubber material, and the surface of the roller has a plurality of anti-slip textures.

[0011] By using rubber rollers, which have excellent anti-slip properties, the friction between the rollers and the slide rail surface can be increased. By adding several anti-slip patterns, the friction between the rollers and the slide rail surface can be further increased, preventing the rollers from slipping and ensuring the rotational power output of the rollers to the drum.

[0012] Preferably, the lubrication unit includes an oil reservoir, which is fixedly installed on one side of the slide rail. Two oil guide grooves are formed on the surface of the slide rail, with one end extending to one side of the oil reservoir. A fixing plate is fixedly installed on one side of the slide rail, and a press pump is fixedly installed on the top of the fixing plate. The output end of the press pump is fixedly connected to a connecting pipe, one end of which is fixedly connected to one side of the oil reservoir. A limiting block for use with the press pump is fixedly installed on one side of the moving template. An oil tank is fixedly installed on one side of the moving template, and an oil delivery pipe is fixedly connected to the bottom of the oil tank. A flow guide hole is formed on one side of the sliding plate, one end of which extends to the bottom of the sliding plate, and one end of the oil delivery pipe is fixedly connected to one end of the flow guide hole.

[0013] By setting up an oil storage tank, the lubricating oil in the tank can be transported to the guide holes on the inner wall of the slide plate through the oil supply pipe. The lubricating oil flows into the bottom of the slide plate through the guide holes, thus lubricating the slide plate when it slides on the slide rail. When the moving template slides to separate the mold, it can drive the limit block to move synchronously. When the moving template moves to the position of the fixed plate, the limit block can squeeze the press pump. The press pump generates negative pressure, which can transport the lubricating oil in the oil storage box to the oil storage tank through the connecting pipe, thereby replenishing the lubricating oil in the oil storage tank. By setting up a guide channel, the metal debris and lubricating oil mixture swept by the cleaning unit can be guided to the oil storage box, thereby enabling the lubricating oil to be recycled.

[0014] Preferably, the bottom of the slide plate is provided with a flow guide groove, and the number of the flow guide grooves is several. The flow guide grooves are arranged in a cross shape, and one of the flow guide grooves is fixedly connected to one end of the flow guide hole.

[0015] By setting up cross-shaped guide grooves, the lubricating oil delivered in the guide hole can be dispersed and flowed to the periphery of the slide plate, thereby enabling the lubricating oil to fully contact and lubricate the slide plate, further reducing the friction between the slide plate and the slide rail, and thus improving the lubrication effect between the slide plate and the slide rail.

[0016] Preferably, the bottom of the oil storage tank is provided with a regulating valve, which is fixedly installed on the inner wall of the oil storage tank.

[0017] By setting a regulating valve, the amount of lubricating oil delivered from the oil storage tank to the oil delivery pipe can be easily controlled, thereby facilitating the adjustment of the flow rate of lubricating oil between the slide plate and the slide rail.

[0018] Preferably, a slide rod is fixedly installed on the inner wall of the oil storage box, and a first sedimentation box and a second sedimentation box are slidably connected to the surface of the slide rod. A conduit is fixedly connected to one side of the first sedimentation box, and one end of the conduit is fixedly connected to one side of the second sedimentation box. Filter plates are fixedly installed on the inner walls of both the first sedimentation box and the second sedimentation box.

[0019] By setting up a first sedimentation box, the mixture of conveying lubricating oil and waste debris in the guide channel can be precipitated. The precipitated mixture flows into a second sedimentation box through a conduit for further sedimentation. By setting up a filter plate, the mixture can be filtered multiple times, thereby separating the lubricating oil and debris in the mixture, thus improving the purity of the lubricating oil during recycling. The sliding connection between the first and second sedimentation boxes and the slide rod allows for easy placement and removal of the first and second sedimentation boxes, and facilitates the disposal of the precipitated debris in the first and second sedimentation boxes.

[0020] Preferably, an extension arc plate is fixedly installed on one side of the slide rail, the position of the extension arc plate corresponds to the position of the guide groove, and one end of the extension arc plate extends to the top of the first sedimentation box.

[0021] By setting an extended arc plate, the lubricating oil and debris mixture on the guide channel can be further diverted into the first sedimentation box, which can prevent the mixed liquid from flowing directly into the storage box, thus enabling the mixture to be fully filtered and precipitated.

[0022] Preferably, the lifting mechanism includes a valve plate, which is fixedly installed on one side of the movable template. One side of the valve plate is fixedly connected to an overflow valve, a stacked check valve, a proportional pressure valve, and a pressure sensor. One side of the stacked check valve is fixedly connected to an electromagnetic directional valve. One side of the valve plate is fixedly connected to a pressure gauge. The top of the valve plate is fixedly connected to an inlet clamping sleeve and an overflow clamping sleeve. The bottom of the valve plate is fixedly connected to an infusion clamping sleeve. One end of the infusion clamping sleeve is fixedly connected to a first hydraulic oil pipe. A flow divider is fixedly installed on one side of the movable template. One end of the first hydraulic oil pipe is fixedly connected to the input end of the flow divider. The output end of the flow divider is fixedly connected to a second hydraulic oil pipe. The input end of the plunger cylinder is fixedly connected to one end of the second hydraulic oil pipe.

[0023] By setting a proportional pressure valve, which is electrically connected to the injection molding machine's control device, and inputting a pressure range via the injection molding machine's operation panel, the required pressure value for the hydraulic support of the bottom plunger cylinder of the moving template can be easily adjusted. Simultaneously, the injection molding machine's control device automatically tracks and sets the pressure limit value of the proportional pressure valve. When the plunger cylinder does not reach the lower limit of the pressure range, the pressure sensor sends an electrical signal, energizing the solenoid directional valve coil. The hydraulic oil circuit of the injection molding machine is connected to the inlet clamp sleeve through the pipeline. The delivered hydraulic oil is supplied to the plunger cylinder synchronously through the superimposed check valve and the solenoid directional valve. After reaching the upper limit of the set pressure range, the pressure sensor sends an electrical signal, causing the solenoid directional valve coil to de-energize and close, and stopping the supply of fluid to the plunger cylinder.

[0024] When the oil pressure in the plunger cylinder is too high, the proportional solenoid coil of the proportional pressure valve and the coil of the solenoid directional valve are simultaneously energized. The hydraulic oil overflows through the solenoid directional valve and the proportional pressure valve to the overflow sleeve. The overflow sleeve is connected to the oil tank of the injection molding machine's hydraulic circuit, allowing the overflowing hydraulic oil to flow into the oil tank. When the oil pressure in the plunger cylinder drops to an appropriate range, the solenoid directional valve coil is de-energized and closes, stopping the overflow. By setting a pressure sensor, the output of which is electrically connected to the control device of the injection molding machine, the oil pressure in the valve plate can be monitored in real time. By setting a superimposed check valve, backflow of hydraulic oil in the valve plate can be prevented. By setting a pressure gauge, the oil pressure in the valve plate can be further detected and displayed.

[0025] Preferably, a diverter is fixedly connected to the surface of the first hydraulic pipe, one end of the diverter is fixedly connected to a third hydraulic oil pipe, an accumulator is fixedly installed on one side of the movable template, and the output end of the accumulator is fixedly connected to one end of the third hydraulic oil pipe.

[0026] By setting up an accumulator, which is connected to the first hydraulic oil pipe through the third hydraulic oil pipe, the accumulator can store and release the hydraulic energy in the lifting mechanism, balance the fluctuation of hydraulic oil pressure in the lifting mechanism, absorb shock and vibration, and maintain the hydraulic oil pressure in the lifting mechanism, thus benefiting the normal operation of the lifting mechanism.

[0027] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention utilizes a cleaning unit. When the moving template moves into and out of the mold, it drives the rollers to roll on the slide rail. The reaction force of the tension spring increases the force of the rollers on the slide rail, thus improving the output of the rolling power. When the rollers rotate, they drive the rotating shaft to rotate on the inner wall of the fixed frame, which in turn drives the roller to rotate. The roller drives the rubber strip to rotate, thereby cleaning the metal debris generated by friction on the slide rail. By setting the spirally arranged rubber strip, the cleaned metal debris can be transported to one side of the slide rail, thus avoiding the accumulation of a large amount of metal debris on the slide rail. This prevents the metal debris from causing further wear and scratches on the slide plate and slide rail, reduces the friction between the slide plate and the slide rail, and maintains smooth movement between the slide plate and the slide rail. This allows the moving template to move smoothly, enabling the injection molding machine to quickly complete the mold closing and opening operations during production, thus improving the production efficiency of the injection molding machine.

[0028] 2. This invention utilizes a lubrication unit. When the moving template slides to separate the mold, it can drive the limiting block to move synchronously. When the moving template moves to the position of the fixed plate, the limiting block can squeeze the pressing pump, which generates negative pressure. This pressure can then transport the lubricating oil in the oil storage box to the oil storage tank through the connecting pipe, thereby replenishing the lubricating oil in the oil storage tank. By setting a guide channel, the mixture of metal debris and lubricating oil swept by the cleaning unit can be guided. By setting an extension arc plate, the mixture of lubricating oil and debris on the guide channel can be further guided to the first sedimentation box, preventing the mixed liquid from flowing directly into the storage box. By setting the first sedimentation box, the mixture of lubricating oil and waste debris transported in the guide channel can be precipitated. The precipitated mixture flows into the second sedimentation box through a conduit for further sedimentation. By setting a filter... The plate can filter the mixture multiple times, separating the lubricant from debris, thus improving the purity of the lubricant during recycling. The filtered and settled lubricating oil flows into the oil storage box through the second sedimentation box, allowing for its recycling. The lubricating oil in the storage tank can be transported to the guide holes on the inner wall of the slide plate through the oil supply pipe. The lubricating oil flows into the bottom of the slide plate through the guide holes, thus lubricating the slide plate as it slides on the rail. By setting up cross-shaped guide grooves, the lubricating oil transported in the guide holes can be dispersed to the periphery of the slide plate, allowing the lubricating oil to fully contact and lubricate the slide plate, reducing the friction between the slide plate and the rail, thereby improving the lubrication effect between the slide plate and the rail, and further improving the smooth movement of the slide plate and the rail.

[0029] 3. This invention utilizes a lifting mechanism, with a proportional pressure valve electrically connected to the injection molding machine's control device. The pressure range is input via the injection molding machine's control panel, allowing for convenient adjustment of the pressure required for the hydraulic support of the piston cylinder at the bottom of the moving template. Simultaneously, the injection molding machine's control device automatically tracks the set pressure limit value of the proportional pressure valve. When the piston cylinder fails to reach the lower limit of the pressure range, the pressure sensor sends an electrical signal, energizing the solenoid directional valve coil. The injection molding machine's hydraulic oil circuit connects to the inlet clamping sleeve via a pipeline, and the supplied hydraulic oil is simultaneously supplied to the piston cylinder through a superimposed check valve and the solenoid directional valve. Once the upper limit of the set pressure range is reached, the pressure sensor sends an electrical signal, de-energizing and closing the solenoid directional valve coil, stopping the supply of fluid to the piston cylinder. When the oil pressure inside the piston cylinder is too high, the proportional solenoid coil of the proportional pressure valve and the solenoid directional valve... When the coils are energized simultaneously, hydraulic oil overflows through the solenoid directional valve and the proportional pressure valve to the overflow clamping sleeve. The overflow clamping sleeve is connected to the oil tank of the injection molding machine's hydraulic oil circuit, allowing the overflowed hydraulic oil to flow into the oil tank. When the oil pressure in the plunger cylinder drops to an appropriate range, the solenoid directional valve coil is de-energized and closes, stopping the overflow. By setting a pressure sensor, the output of which is electrically connected to the injection molding machine's control device, the oil pressure in the valve plate can be monitored in real time. By setting a superimposed check valve, backflow of hydraulic oil in the valve plate can be prevented. By setting a pressure gauge, the oil pressure in the valve plate can be further detected and displayed. When there is a significant change in the weight of the mold on the moving template, the pressure range can be adjusted via the operation panel, allowing for quick adjustment of the piston cylinder's support force on the moving template. The pressure adjustment operation is very convenient. Attached Figure Description

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1 Please see Figure 1-11 This invention provides a technical solution: a sliding foot mechanism for an injection molding machine template. This invention addresses the technical problems mentioned in the background section by making corresponding improvements. It includes a movable template 1, with four pull rods slidably connected to the inner wall of the movable template 1. Four plunger cylinders 12 are fixedly installed at the bottom of the movable template 1. A bearing plate 13 is fixedly installed at the output end of the plunger cylinder 12. A sliding plate 14 is slidably connected to the surface of the bearing plate 13. A slide rail 15 is provided at the bottom of the movable template 1, with the surface of the sliding plate 14 slidably connected to the surface of the slide rail 15. A cleaning and lubrication mechanism 2 is provided at the bottom of the movable template 1.

[0034] As a further definition of the cleaning and lubrication mechanism 2 of the present invention, the cleaning and lubrication mechanism 2 includes a cleaning unit 21, the cleaning unit 21 includes a tension spring 2101, one end of the tension spring 2101 is fixedly installed at the bottom of the movable template 1, there are two tension springs 2101, one end of the tension spring 2101 is fixedly installed with a fixing frame 2102, the inner wall of the fixing frame 2102 is rotatably connected with a rotating shaft 2103, the surface of the rotating shaft 2103 is fixedly installed with a roller 2104, the surface of the roller 2104 is slidably connected with the surface of the slide rail 15, one end of the rotating shaft 2103 is fixedly installed with a roller 2105, the surface of the roller 2105 is fixedly installed with a rubber strip 2106, there are several rubber strips 2106, the rubber strips 2106 are arranged in a spiral shape.

[0035] The roller 2104 is made of rubber material, and the surface of the roller 2104 is provided with several anti-slip textures 2107. By using rubber material for the roller 2104, the excellent anti-slip performance of the rubber material can increase the friction between the roller 2104 and the surface of the slide rail 15. By providing several anti-slip textures 2107, the friction between the roller 2104 and the surface of the slide rail 15 can be further increased, which can prevent the roller 2104 from slipping, thereby ensuring the rotational power output of the roller 2104 to the drum 2105.

[0036] The specific implementation of this embodiment is as follows: When the movable template 1 moves into and out of the mold, it can drive the roller 2104 to roll on the slide rail 15. Through the reaction force of the tension spring 2101, the force of the roller 2104 on the slide rail 15 can be increased, which can benefit the output of the rolling power of the roller 2104. When the roller 2104 rotates, it can drive the rotating shaft 2103 to rotate on the inner wall of the fixed frame 2102, which can drive the roller 2105 to rotate. The roller 2105 can drive the rubber strip 2106 to rotate, which can generate friction on the slide rail 15. The metal debris is cleaned by setting spirally arranged rubber strips 2106, which can transport the cleaned metal debris to one side of the slide rail 15, thereby avoiding a large amount of metal debris accumulating on the slide rail 15. This prevents the metal debris from causing further wear and scratches on the slide plate 14 and the slide rail 15, reduces the friction between the slide foot and the slide rail 15, and maintains smooth movement between the slide plate 14 and the slide rail 15. This allows the moving template 1 to move smoothly, enabling the injection molding machine to quickly complete the mold closing and opening operations during the production process, thus improving the production efficiency of the injection molding machine.

[0037] Example 2 Please see Figure 1-11The present invention provides a technical solution: a sliding foot mechanism for injection molding machine templates. The present invention makes corresponding improvements to the technical problems mentioned in the background art. The cleaning and lubrication mechanism 2 also includes a lubrication unit 22, which works in conjunction with the cleaning unit 21 to lubricate the slide plate 14 when it moves on the slide rail 15.

[0038] As a further limitation of the cleaning and lubrication mechanism 2 of the present invention, the lubrication unit 22 includes an oil storage box 2201, which is fixedly installed on one side of the slide rail 15. Two oil guide grooves 2202 are formed on the surface of the slide rail 15, with one end of each groove extending to one side of the oil storage box 2201. A fixing plate 2203 is fixedly installed on one side of the slide rail 15, and a pressing pump 2204 is fixedly installed on the top of the fixing plate 2203. The output end of the pressing pump 2204 is fixedly connected to a connecting pipe. 2205, one end of the connecting pipe 2205 is fixedly connected to one side of the oil storage box 2201, a limiting block 2206 for use with the pressing pump 2204 is fixedly installed on one side of the moving template 1, an oil storage tank 2207 is fixedly installed on one side of the moving template 1, an oil delivery pipe 2208 is fixedly connected to the bottom of the oil storage tank 2207, a guide hole 2209 is opened on one side of the slide plate 14, one end of the guide hole 2209 extends to the bottom of the slide plate 14, and one end of the oil delivery pipe 2208 is fixedly connected to one end of the guide hole 2209.

[0039] The bottom of the slide plate 14 is provided with a guide groove 2210. There are several guide grooves 2210, which are arranged in a cross pattern. One of the guide grooves 2210 is fixedly connected to one end of the guide hole 2209. By setting the cross-shaped guide grooves 2210, the lubricating oil delivered in the guide hole 2209 can be dispersed and flowed to the periphery of the slide plate 14, so that the lubricating oil can fully contact and lubricate the slide plate 14, which can further reduce the friction between the slide plate 14 and the slide rail 15, thereby improving the lubrication effect between the slide plate 14 and the slide rail 15.

[0040] A regulating valve 2211 is provided at the bottom of the oil storage tank 2207. The regulating valve 2211 is fixedly installed on the inner wall of the oil storage tank 2207. By setting the regulating valve 2211, the amount of lubricating oil delivered from the oil storage tank 2207 to the oil delivery pipe 2208 can be easily controlled, thereby facilitating the adjustment of the flow rate of lubricating oil between the slide plate 14 and the slide rail 15.

[0041] A slide rod 2212 is fixedly installed on the inner wall of the oil storage box 2201. A first sedimentation box 2213 and a second sedimentation box 2214 are slidably connected to the surface of the slide rod 2212. A conduit 2215 is fixedly connected to one side of the first sedimentation box 2213, and one end of the conduit 2215 is fixedly connected to one side of the second sedimentation box 2214. Filter plates 2216 are fixedly installed on the inner walls of both the first sedimentation box 2213 and the second sedimentation box 2214. By setting the first sedimentation box 2213, the mixture of conveying lubricating oil and waste in the guide channel 2210 can be precipitated. The precipitated mixture... The liquid flows into the second sedimentation box 2214 through the conduit 2215 for further sedimentation. By setting the filter plate 2216, the mixture can be filtered multiple times, thereby separating the lubricant and debris in the mixture and improving the purity of the lubricant during recycling. The sliding connection between the first sedimentation box 2213 and the second sedimentation box 2214 and the slide rod 2212 makes it easy to pick up and put in the first sedimentation box 2213 and the second sedimentation box 2214, and makes it easy to pour out the sediment in the first sedimentation box 2213 and the second sedimentation box 2214.

[0042] An extension arc plate 2217 is fixedly installed on one side of the slide rail 15. The position of the extension arc plate 2217 corresponds to the position of the guide channel 2210. One end of the extension arc plate 2217 extends to the top of the first sedimentation box 2213. By setting the extension arc plate 2217, the lubricating oil and debris mixture on the guide channel 2210 can be further guided into the first sedimentation box 2213, which can prevent the mixed liquid from flowing directly into the storage box, thereby enabling the mixed liquid to be fully filtered and precipitated.

[0043] The specific implementation of this embodiment is as follows: When the movable template 1 slides to separate the mold, it can drive the limiting block 2206 to move synchronously. When the movable template 1 moves to the position of the fixed plate 2203, the limiting block 2206 can squeeze the pressing pump 2204. The pressing pump 2204 generates negative pressure, which can transport the lubricating oil in the oil storage box 2201 to the oil storage tank 2207 through the connecting pipe 2205, thereby replenishing the lubricating oil in the oil storage tank 2207. By setting the guide groove 2210, it can... The metal shavings and lubricating oil mixture swept by the cleaning unit 21 is guided by an extended arc plate 2217, which further guides the lubricating oil and shavings mixture on the guide channel 2210 into the first sedimentation box 2213, preventing the mixture from flowing directly into the storage box. The first sedimentation box 2213 also allows for sedimentation of the lubricating oil and waste shavings mixture in the guide channel 2210. The settled mixture then flows through a conduit 2215 into the second sedimentation box 2214 for further sedimentation. By setting the filter plate 2216, the mixture can be filtered multiple times, thereby separating the lubricant and debris in the mixture, which can improve the purity of the lubricant when it is recycled. The filtered and settled lubricating oil flows into the oil storage box 2201 through the second sedimentation box 2214, which can be recycled. The lubricating oil in the oil storage tank 2207 can be transported to the guide hole 2209 on the inner wall of the slide plate 14 through the oil supply pipe 2208. The lubricating oil flows into the bottom of the slide plate 14 through the guide hole 2209, which can lubricate the slide plate 14 when it slides on the slide rail 15. By setting the cross-shaped guide groove 2210, the lubricating oil transported in the guide hole 2209 can be dispersed to the periphery of the slide plate 14, which can make full contact lubrication between the lubricating oil and the slide plate 14, reduce the friction between the slide plate 14 and the slide rail 15, and thus improve the lubrication effect between the slide plate 14 and the slide rail 15, which can further improve the smooth movement between the slide plate 14 and the slide rail 15.

[0044] Example 3 Please see Figure 1-11 The present invention provides a technical solution: a sliding foot mechanism for injection molding machine templates. The present invention makes corresponding improvements to the technical problems mentioned in the background art. A lifting mechanism 3 is provided on one side of the movable template 1. The lifting mechanism 3 is used to support the movable template 1, which can reduce the bending moment of the movable template 1 on the tie rod 11 to a minimum and ensure that the tie rod 11 is always in a horizontal state.

[0045] As a further definition of the lifting mechanism 3 of the present invention, the lifting mechanism 3 includes a valve plate 31, which is fixedly installed on one side of the movable template 1. One side of the valve plate 31 is fixedly connected to an overflow valve 32, a stacked check valve 33, a proportional pressure valve 34, and a pressure sensor 35. One side of the stacked check valve 33 is fixedly connected to an electromagnetic directional valve 36. One side of the valve plate 31 is fixedly connected to a pressure gauge 37. The top of the valve plate 31 is fixedly connected to an inlet clamping sleeve 38 and an overflow clamping sleeve 39. The bottom of the valve plate 31 is fixedly connected to an infusion clamping sleeve 310. One end of the infusion clamping sleeve 310 is fixedly connected to a first hydraulic oil pipe 311. One side of the movable template 1 is fixedly installed with a flow divider 312. One end of the first hydraulic oil pipe 311 is fixedly connected to the input end of the flow divider 312. The output end of the flow divider 312 is fixedly connected to a second hydraulic oil pipe 313. The input end of the plunger cylinder 12 is fixedly connected to one end of the second hydraulic oil pipe 313.

[0046] A diverter 314 is fixedly connected to the surface of the first hydraulic pipe. One end of the diverter 314 is fixedly connected to the third hydraulic oil pipe 315. An accumulator 316 is fixedly installed on one side of the movable template 1. The output end of the accumulator 316 is fixedly connected to one end of the third hydraulic oil pipe 315. By setting the accumulator 316, the accumulator 316 is connected to the first hydraulic oil pipe 311 through the third hydraulic oil pipe 315. The accumulator 316 can store and release the hydraulic energy in the lifting mechanism 3, balance the fluctuation of the hydraulic oil pressure in the lifting mechanism 3, absorb shock and vibration, and maintain the pressure of the hydraulic oil in the lifting mechanism 3, thereby benefiting the normal operation of the lifting mechanism 3.

[0047] The specific implementation of this embodiment is as follows: The proportional pressure valve 34 is electrically connected to the control device of the injection molding machine. The pressure value range is input through the operation panel of the injection molding machine, which can easily adjust the pressure value required for the hydraulic support of the bottom plunger cylinder 12 of the moving template 1. At the same time, the control device of the injection molding machine automatically tracks the set pressure limit value of the proportional pressure valve 34. When the plunger cylinder 12 does not reach the lower limit value of the pressure value range, the pressure sensor 35 sends an electrical signal, the coil of the solenoid directional valve 36 is energized, and the hydraulic oil circuit of the injection molding machine is connected to the inlet clamping sleeve through the pipeline. 38 is connected, and the hydraulic oil being supplied is simultaneously supplied to the piston cylinder 12 through the superimposed check valve 33 and the solenoid directional valve 36. Once the upper limit of the set pressure range is reached, the pressure sensor 35 sends an electrical signal, de-energizing the coil of the solenoid directional valve 36 and stopping the supply of fluid to the piston cylinder 12. When the oil pressure inside the piston cylinder 12 is too high, the proportional solenoid coil of the proportional pressure valve 34 and the coil of the solenoid directional valve 36 are simultaneously energized, and the hydraulic oil overflows through the solenoid directional valve 36 and the proportional pressure valve 34 to the overflow sleeve 39. The overflow clamp 39 is connected to the oil tank of the injection molding machine's hydraulic oil circuit, allowing the overflowing hydraulic oil to flow back into the tank. When the oil pressure in the plunger cylinder 12 drops to an appropriate range, the coil of the solenoid directional valve 36 is de-energized and closes, stopping the overflow. A pressure sensor 35, whose output is electrically connected to the injection molding machine's control device, allows for real-time monitoring of the oil pressure in the valve plate 31. A superimposed check valve 33 prevents backflow of hydraulic oil from the valve plate 31. The pressure gauge 37 can further detect and display the oil pressure in the valve plate 31. When the weight of the mold on the moving template 1 changes significantly, the pressure range can be adjusted by the operation panel of the injection molding machine. The support force of the piston cylinder on the moving template 1 can be quickly adjusted. The pressure adjustment operation is very convenient. The four piston cylinders 12 can provide equal pressure support for the moving template 1, so that the bending moment of the moving template 1 on the tie rod 11 is reduced to a minimum, ensuring that the tie rod 11 is always in a horizontal state, and improving the working performance of the mold closing components on the moving template 1.
