Description
Technical Field
[0001] The present invention relates to the technical field of lubrication equipment, in particular to an automatic lubrication control system for a shot shot head. Background Art
[0002] At present, the injection head of the die-casting machine generally works at high temperature. Due to the unreasonable material, heat treatment process and cooling method of the injection head, severe wear or corrosion will occur after a short period of use. Frequent replacement of new injection heads in production is time-consuming and labor-intensive, which reduces production efficiency and increases production costs. The die-casting machine is a precision casting equipment that uses high pressure to quickly inject molten metal liquid into a mold and solidifies it into shape through cooling.
[0003] In the prior art, the shot head is an important component of the die-casting machine. During the injection process, the temperature will rise sharply, which will cause the overall cooling rate of the metal liquid to decrease, affecting the condensation time of the casting product, and easily leading to product quality problems such as shrinkage holes and burning. It will also reduce the service life of the shot head. Therefore, the shot head must be circulated with coolant to reduce the temperature in order to increase the service life of the shot head. In the die-casting process of the shot head, it is necessary to spray lubricant on the shot head. If lubricant is not used, the wear between the side wall of the shot head and the die-casting tube will increase, resulting in a reduction in the service life of the shot head. At the same time, the lubricant must not be repeatedly filtered or waste chips collected. Long-term use will reduce the lubrication effect and accelerate the wear on the side wall of the shot head.

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0034] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.
[0035] Example:
[0036] Reference Figures 1-8, an automatic lubrication control system for a shooting head, comprising a movable box 1 with a shooting head body 19, a guide channel 704 is opened in the working end of the shooting head body 19, and the coolant can be transported to the shooting head body 19 through the guide channel 704 for continuous cooling circulation and cooling. An oil pump 2 and a storage cylinder 4 are also installed in the box 1, and the output end of the oil pump 2 is connected to the storage cylinder 4 through an oil inlet pipe 201, and the input end of the oil pump 2 is fixedly connected to the oil tank. When the oil pump 2 is working, the lubricating oil can be transported to the storage cylinder 4 through the oil tank, and then the filter cartridge 401 is used to filter it for the first time, and then the lubricating oil is transported to the shooting head body 19. In order to facilitate the cleaning of impurities in the storage cylinder 4, the storage cylinder 4 can be unscrewed, and the filter cartridge 401 can be pulled out to the outside, and then replaced and cleaned, thereby reducing the impurities in the lubricating oil transported to the shooting head body 19 and improving the subsequent lubrication effect.
[0037] In addition, when the oil pump 2 is working, the lubricating oil may generate more heat during the process of delivering the lubricating oil. In order to facilitate the cooling of the lubricating oil, a liquid storage tank 8 is also installed in the box body 1, and the liquid storage tank 8 is filled with coolant. The output end of the negative pressure pump 7 is connected to the working box 3 through the liquid outlet pipe 701, so that the coolant can be delivered to the working box 3 to cool the delivered lubricating oil, so as to improve the lubricating effect of the subsequent lubricating oil. A connecting column 9 is also installed on the box body 1, and an oil cavity 901 is opened in the connecting column 9. An oil delivery pipe 902 is provided in the connecting column 9, wherein the oil delivery pipe 902 is respectively connected to the oil cavity 901 and the liquid outlet end of the injection head body 19. When the lubricating oil enters the injection head body 19 through the oil delivery pipe 902 When the injection molding machine is in operation, a plurality of grooves are provided on the side wall of the injection molding machine body 19 so that the lubricating oil can be sprayed on the inner wall of the die-cast tube when working, thereby reducing the wear between the side wall of the injection molding machine body 19 and the die-cast tube, and improving the service life of the injection molding machine body 19 while reducing the factory's use cost. When the injection molding machine body 19 returns to its original position, the input end of the oil pump 2 works to absorb the lubricating oil on the injection molding machine body 19 into the oil delivery pipe 902 through the groove for reflux effect. In this process, steel chips may be mixed in the lubricating oil. In order to facilitate the filtering of the lubricating oil, a filter box 10 is fixedly connected to the box body 1, and a filter screen 11 is provided in the filter box 10. A push plate 12 is slidably connected to the filter box 10, and the push plate 12 is in contact with the end face of the filter screen 11. The filter box 10 is fixedly connected with a magnet 1001, which cooperates with the filter screen 11, and the working box 3 is also fixedly connected with a booster cylinder 5, which is connected to the oil chamber 901 through a connecting pipe 503. A valve body is provided on the connecting pipe 503, which is a solenoid valve. The booster cylinder 5 passes through the working box 3 and abuts against the filter box 10. A slider 501 is slidably connected to the booster cylinder 5, and the push rod 6 is fixedly connected to the slider 501. A first spring 502 is fixedly connected to the booster cylinder 5, and the two ends of the first spring 502 are respectively fixedly connected to the slider 501 and the booster cylinder 5. A channel with the same diameter as the push rod 6 is also provided at one end of the booster cylinder 5 close to the filter box 10. When the oil delivery pipe 902 is delivered to the filter box 1 through the oil chamber 901, the oil 0, the electromagnetic valve on the connecting pipe 503 automatically closes the pipeline, and the lubricating oil is transported to the filter box 10, and the lubricating oil is filtered through the filter screen 11. When the steel chips are blocked on the filter screen 11, and multiple groups of magnets 1001 are provided on the upper end of the filter screen 11, the magnets 1001 can generate magnetic attraction for the steel chips, and the magnets 1001 maintain a relative distance from the filter screen 11, so that the steel chips can be kept floating upward while being filtered by the filter screen 11, so that the steel chips remain on the surface of the filter screen 11, thereby filtering the lubricating oil. On the one hand, it can improve the effect of cleaning steel chips during long-term use and reduce the cost of repeated replacement of lubricating oil. On the other hand, it can also reduce the wear of the injection head body 19 during use.Improve the practicality of the device.
[0038] Reference Figures 1-6 It should be explained that, in order to facilitate the scraping and collection of steel chips on the filter screen 11, when the oil pump 2 is circulating and working, the lubricating oil is delivered to the storage cylinder 4 through the oil inlet pipe 201, and the lubricating oil will push the slider 501 to move under the action of high pressure, and at the same time drive the push rod 6 to move into the filter box 10. During this process, the first spring 502 is stretched outward, and at the same time the electric telescopic rod 14 drives the baffle 1401 to rise, and the push rod 6 pushes the push plate 12 in the filter box 10 to move, thereby pressing the filter screen. The steel chips on the surface of the filter box 11 are scraped off and pushed to the through hole on one side of the filter box 10. A shield is fixedly connected to the side wall of the filter box 10. In order to facilitate the cleaning of the steel chips on the push plate 12, a scraper 16 that can fit with the end face of the push plate 12 is installed in the shield. In order to facilitate the driving of the scraper 16, a working disk 15 is also fixedly connected in the box body 1, and a rotating shaft 1501 is rotatably connected to the working disk 15. One end of the rotating shaft 1501 is fixedly connected to a turbine blade 1502, and then the scraper 16 is fixedly connected to the work disk 15. The other end of the rotating shaft 1501 is connected, and one side of the working disk 15 is connected to the return pipe 705. A negative pressure pump 7 is also installed in the box body 1, and the output end of the negative pressure pump 7 is connected to the working box 3 through the liquid outlet pipe 701. The working box 3 is connected to the input end of the guide channel 704 through the guide pipe 703, so that the coolant is transported to the guide channel 704 to circulate and cool the heat generated therein. Then, the coolant with heat is transported to one side of the working disk 15 through the return pipe 705. In the process of the coolant flowing, the coolant is cooled. During the process, the turbine blade 1502 will be driven to rotate, thereby driving the scraper 16 to rotate and centrifugally scrape the end face of the push plate 12, and then the second spring 13 fixedly connected to the push plate 12 is reset to keep the filter box 10 sealed. On the one hand, the scraper 16 can automatically and continuously scrape off the steel chips adsorbed on the push plate 12 to ensure the subsequent filtering and cleaning of impurities in the lubricating oil. On the other hand, the shield can also be used to collect the cleaned steel chips to reduce the cleaning burden of subsequent staff.
[0039] Reference Figure 2 、 Figure 5 and Figure 6In order to improve the heat dissipation effect of the coolant, a heat dissipation box 17 is fixedly connected to the box body 1, and a dust interception net is provided at the air outlet of the heat dissipation box 17 to prevent external impurities from affecting the heat dissipation. A "U"-shaped tube 18 is also fixedly connected to the heat dissipation box 17, and the input end of the "U"-shaped tube 18 is fixedly connected to the other side of the working disk 15 through a pipeline. The output end of the "U"-shaped tube 18 is connected to the liquid storage tank 8, and the input end of the negative pressure pump 7 is connected to the liquid storage tank 8 through the liquid inlet pipe 702. A motor is fixedly connected to the top, and the output end of the motor extends to the heat dissipation box 17 and is rotatably connected to the fan blades. The fan blades cooperate with the "U"-shaped tube 18. Increasing the "U"-shaped tube 18 can slow down the circulation speed of the coolant, thereby accelerating the real-time heat dissipation of the coolant flowing in the "U"-shaped tube 18, and then flowing into the liquid storage tank 8, so as to achieve the effect of repeated circulation heat dissipation, and a thermometer is fixedly connected to the liquid storage tank 8, and the temperature of the coolant can be monitored and alarmed in real time through the thermometer to ensure the stability of the subsequent temperature.
