Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of lubrication devices for injection punches in die casting machines, and in particular to a lubrication device for injection punches in die casting machines. Background Technology
[0002] As a key piece of equipment for metal forming in modern manufacturing, die casting machines play an indispensable role in many fields such as automotive parts manufacturing and electronic product casing production. During the die casting process, the injection punch is responsible for injecting molten metal into the mold cavity at high speed and high pressure. Due to the harsh conditions of high temperature, high pressure and scouring of molten metal during the die casting process, the injection punch needs good lubrication to reduce wear, extend service life, ensure die casting quality and improve production efficiency.
[0003] Currently, the method of using a liquid pump and nozzle to spray lubricating oil onto the punch for lubrication is widely used. However, during the lubrication process, a large amount of lubricating oil is sprayed onto the punch to ensure sufficient lubrication, but during the movement of the punch, a considerable portion of the lubricating oil becomes excess. This excess lubricating oil drips directly onto the working area around the die-casting machine, not only causing oil stains all over the work site, making cleaning difficult and costly, but also seriously affecting the cleanliness of the working environment and posing a potential threat to the safety of operators. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a lubrication device for the injection punch of a die-casting machine.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a lubrication device for a die-casting machine injection punch, comprising a base plate and a punch body, a storage tank fixedly connected to the base plate, a liquid pump fixedly connected to the storage tank, a nozzle provided at the output end of the liquid pump, a recovery structure provided on the base plate, the recovery structure mainly consisting of two uprights, both of which are fixedly connected to the base plate, a fixing ring fixedly connected to both uprights, a sponge fixedly connected to the fixing ring, the sponge being sleeved on the outer surface of the punch body, an annular groove being formed in the fixing ring, and several circular holes being formed on the inner wall of the annular groove, and a collection box fixedly connected to the base plate.
[0006] The effect achieved by the above components is as follows: when the liquid pump is started, the liquid pump pumps the lubricating oil in the storage tank to the nozzle and sprays it onto the punch body. When the punch body moves back and forth in the injection cylinder wall, the excess lubricating oil is absorbed by the sponge. If too much lubricating oil is absorbed, it will enter the annular groove and then flow through several round holes to the collection box for collection. This avoids the excess lubricating oil from dripping directly onto the working area around the die-casting machine, which not only causes oil stains all over the work site, making cleaning difficult and costly, but also seriously affects the cleanliness of the working environment and poses a potential threat to the safety of operators.
[0007] Preferably, the fixed ring has an annular groove, a slider is slidably connected in the annular groove, and an extrusion cylinder is rotatably connected to the slider via a bearing.
[0008] The effect achieved by the above components is that the slider slides along the annular groove, causing the extrusion cylinder to squeeze the sponge and squeeze the lubricating oil absorbed by the sponge into the annular groove.
[0009] Preferably, a disc gear is rotatably connected to the fixed ring via a bearing, and the disc gear is fixedly connected to the slider.
[0010] The effect achieved by the above components is that the rotating disk gear can drive the slider to slide along the annular groove.
[0011] Preferably, a fixing plate is fixedly connected to the base plate, and a spur gear is rotatably connected to the fixing plate via a bearing. The spur gear meshes with a disc gear, and a motor is fixedly connected to the fixing plate. The spur gear is driven to rotate by the motor.
[0012] The effect achieved by the above components is that the output end of the motor is connected to the spur gear through the reducer and the coupling. When the motor is started, the spur gear can be driven to rotate, which in turn drives the disc gear to rotate, making the operation more convenient.
[0013] Preferably, the storage tank is provided with an adjustment structure, which mainly consists of a mounting column. The mounting column is fixedly connected to the storage tank and is slidably connected to the connecting rod of the nozzle. A sliding groove is provided on the mounting column, and two sliding plates are slidably connected in the sliding groove. A clamping block is fixedly connected to the sliding plate, and a rubber pad is fixedly connected to the clamping block.
[0014] The effects achieved by the above components are as follows: the output end of the liquid pump is fixedly connected to the nozzle through a hose, and the distance between the nozzle and the punch body can be adjusted by sliding the connecting rod of the nozzle to adapt to different production requirements. After the nozzle position is adjusted, the two sliding plates are moved closer to each other, so that the two clamping blocks clamp and limit the connecting rod of the nozzle. The rubber pad can improve the clamping effect.
[0015] Preferably, magnetic blocks are embedded and fixedly connected to both ends of the clamping block, and the two surfaces of the two magnetic blocks that come into contact with each other are opposite poles that attract each other.
[0016] The effect achieved by the above components is that after clamping, the two magnetic blocks attract each other under the action of magnetic force, making the clamping more stable.
[0017] Preferably, a bidirectional screw is rotatably connected to the sliding groove via a bearing, the two sections of the bidirectional screw have opposite thread directions, and the bidirectional screw is threadedly connected to two sliding plates.
[0018] The effect achieved by the above components is that rotating the bidirectional screw can drive the two slide plates to slide synchronously in opposite directions, making operation more convenient.
[0019] Preferably, a sliding block is slidably connected to one of the skateboards, and a slot is provided on the sliding block; a locking block is fixedly connected to another of the skateboards.
[0020] The effect achieved by the above components is that the sliding block allows the locking block to engage in the slot, which further limits the sliding plate and prevents the bidirectional screw from rotating during clamping.
[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this utility model, by setting up a recovery structure and starting the liquid pump, the liquid pump pumps the lubricating oil in the storage tank to the nozzle and sprays it onto the punch body. When the punch body moves back and forth in the injection cylinder wall, the excess lubricating oil is absorbed by the sponge. If too much lubricating oil is absorbed, it will enter the annular groove and then flow through several round holes to the collection box for collection. This avoids the problem of excess lubricating oil dripping directly onto the working area around the die-casting machine, which not only causes oil stains all over the work site, making cleaning difficult and costly, but also seriously affects the cleanliness of the working environment and poses a potential threat to the safety of operators.

[0028] Example 1, as Figure 1 As shown, a lubrication device for a die-casting machine injection punch includes a base plate 1 and a punch body 2. A storage tank 3 is fixedly connected to the base plate 1, and a liquid pump 4 is fixedly connected to the storage tank 3. A nozzle 5 is provided at the output end of the liquid pump 4.
[0029] Reference Figure 2 , Figure 3 and Figure 5A recycling structure 6 is provided on the base plate 1. The recycling structure 6 mainly consists of two uprights 61, both of which are fixedly connected to the base plate 1. A fixing ring 62 is fixedly connected to both uprights 61, and a sponge 63 is fixedly connected to the fixing ring 62. The sponge 63 is sleeved on the outer surface of the punch body 2. A ring groove 67 is opened in the fixing ring 62, and several round holes 68 are opened on the inner wall of the ring groove 67. A collection box 69 is fixedly connected to the base plate 1. The liquid pump 4 is started, and the liquid pump 4 pumps the lubricant in the storage tank 3. The oil pump supplies oil to nozzle 5 and sprays it onto the punch body 2. As the punch body 2 moves back and forth in the injection cylinder wall, excess lubricating oil is absorbed by the sponge 63. If too much lubricating oil is absorbed, it will enter the annular groove 67 and then flow through several round holes 68 to the collection box 69 for collection. This avoids excess lubricating oil dripping directly onto the working area around the die-casting machine, which not only causes oil stains all over the work site, making cleaning difficult and costly, but also seriously affects the cleanliness of the working environment and poses a potential threat to the safety of operators. The fixed ring 62 has an annular groove 64, in which a slider 65 is slidably connected. The slider 65 is rotatably connected to the extrusion cylinder 66 via a bearing. Sliding the slider 65 along the annular groove 64 causes the extrusion cylinder 66 to squeeze the sponge 63, squeezing the lubricating oil absorbed by the sponge 63 into the annular groove 67. The fixed ring 62 is rotatably connected to the disc gear 610 via a bearing. The disc gear 610 is fixedly connected to the slider 65. Rotating the disc gear 610 can drive the slider 65 along the annular groove 64. The groove 64 slides, and a fixed plate 612 is fixedly connected to the base plate 1. A spur gear 613 is rotatably connected to the fixed plate 612 through a bearing. The spur gear 613 meshes with the disc gear 610. A motor 611 is fixedly connected to the fixed plate 612. The spur gear 613 is driven to rotate by the motor 611. The output end of the motor 611 is connected to the spur gear 613 through a reducer and a coupling. Starting the motor 611 can drive the spur gear 613 to rotate, which in turn drives the disc gear 610 to rotate, making the operation more convenient.
[0030] Reference Figure 4The storage tank 3 is equipped with an adjustment structure 7, which mainly consists of a mounting column 71. The mounting column 71 is fixedly connected to the storage tank 3 and is slidably connected to the connecting rod of the nozzle 5. The mounting column 71 has a sliding groove 72, in which two sliding plates 73 are slidably connected. A clamping block 74 is fixedly connected to the sliding plate 73, and a rubber pad is fixedly connected to the clamping block 74. The output end of the liquid pump 4 is fixedly connected to the nozzle 5 through a hose. The distance between the nozzle 5 and the punch body 2 can be adjusted by sliding the connecting rod of the nozzle 5 to adapt to different production requirements. After the position of the nozzle 5 is adjusted, the two sliding plates 73 are slid closer to each other, so that the two clamping blocks 74 clamp and limit the connecting rod of the nozzle 5. The rubber pad can improve the clamping effect. Two magnetic blocks 75 are fixedly embedded at both ends. The two surfaces of the two magnetic blocks 75 that come into contact with each other are opposite poles and attract each other. After clamping, the two magnetic blocks 75 are attracted together by magnetic force, making the clamping more stable. A bidirectional screw 76 is rotatably connected to the sliding groove 72 through a bearing. The two sections of the bidirectional screw 76 have opposite threads and are threaded to the two slide plates 73. Rotating the bidirectional screw 76 can drive the two slide plates 73 to slide synchronously in opposite directions, making the operation more convenient. A sliding block 77 is slidably connected to one slide plate 73. The sliding block 77 has a slot 78. A locking block 79 is fixedly connected to one slide plate 73. Sliding the sliding block 77 causes the locking block 79 to engage in the slot 78, which can further limit the slide plate 73 and prevent the bidirectional screw 76 from rotating during the clamping process.
[0031] Working principle: The hydraulic pump 4 is started, pumping lubricating oil from the storage tank 3 to the nozzle 5 and spraying it onto the punch body 2. As the punch body 2 moves back and forth in the injection cylinder wall, excess lubricating oil is absorbed by the sponge 63. Excess lubricating oil absorbed will enter the annular groove 67 and then flow through several round holes 68 to the collection box 69 for collection. This avoids excess lubricating oil dripping directly onto the work area around the die-casting machine, which not only causes oil stains everywhere, making cleaning difficult and costly, but also seriously affects the cleanliness of the work environment and poses a potential threat to the safety of operators. The slider 65 slides along the annular groove 64, causing the extrusion cylinder 66 to squeeze the sponge 63, squeezing the lubricating oil absorbed in the sponge 63 into the annular groove 67. The rotating disc gear 610 drives the slider 65 to slide along the annular groove 64. The output end of the motor 611 is connected to a reducer and a connecting... The shaft is connected to the spur gear 613. Starting the motor 611 can drive the spur gear 613 to rotate, which in turn drives the disc gear 610 to rotate, making operation more convenient. The output end of the liquid pump 4 is fixedly connected to the nozzle 5 through a hose. The distance between the nozzle 5 and the punch body 2 can be adjusted by sliding the connecting rod of the nozzle 5 to adapt to different production requirements. After the position of the nozzle 5 is adjusted, the two sliding plates 73 are slid closer to each other, so that the two clamping blocks 74 clamp and limit the connecting rod of the nozzle 5. The rubber pad can improve the clamping effect. After clamping, the two magnetic blocks 75 are attracted together under the action of magnetic force, making the clamping more stable. Rotating the bidirectional screw 76 can drive the two sliding plates 73 to slide synchronously in opposite directions, making operation more convenient. Sliding the sliding block 77 can make the locking block 79 lock into the locking slot 78, which can further limit the sliding plate 73 and prevent the bidirectional screw 76 from rotating during the clamping process.
