Abstract
The plunger lubricating structure comprises a plunger lubricating structure, wherein the root of a sleeve is provided with an injection plunger, the root of the sleeve is provided with a longitudinal sealing oil duct and a transverse sealing oil duct which are mutually and vertically connected, the longitudinal sealing oil duct and the transverse sealing oil duct are connected with an oil outlet, the lower end of the oil outlet is positioned on the inner side surface of the sleeve, the connection part of the rear end of the sleeve and the injection plunger is provided with an injection plunger lubricating threaded interface, and the longitudinal sealing oil duct and the transverse sealing oil duct. The punch lubricating structure of the utility model prolongs the service life of the injection punch; the service life of the sleeve is prolonged; the production efficiency caused by frequent exchange of the injection head and the sleeve is reduced; the fluctuation of the injection head during injection is reduced, and the incidence rate of low-speed change is reduced.
Description
Technical Field
The utility model relates to a die-casting equipment technical field.
Background
An injection head and a sleeve of the die casting machine are key die casting core components, belong to consumables and need to be exchanged regularly, and are short in service life; the production efficiency is low because the injection head and the sleeve are frequently exchanged; the injection head fluctuates during injection, and the occurrence rate of low-speed fluctuation is high.
Disclosure of Invention
In order to solve the above-mentioned problem that current die casting machine's injection head and sleeve exist, the utility model provides a drift lubricating structure.
The utility model discloses a realize that the technical scheme that above-mentioned purpose adopted is: the plunger lubricating structure comprises a plunger lubricating structure, wherein the root of a sleeve is provided with an injection plunger, the root of the sleeve is provided with a longitudinal sealing oil duct and a transverse sealing oil duct which are mutually and vertically connected, the longitudinal sealing oil duct and the transverse sealing oil duct are connected with an oil outlet, the lower end of the oil outlet is positioned on the inner side surface of the sleeve, the connection part of the rear end of the sleeve and the injection plunger is provided with an injection plunger lubricating threaded interface, and the longitudinal sealing oil duct and the transverse sealing oil duct.
The sleeve is fixedly installed outside the sleeve through a sleeve positioning pin and a sleeve positioning bolt.
The punch lubricating structure of the utility model prolongs the service life of the injection punch; the service life of the sleeve is prolonged; the production efficiency caused by frequent exchange of the injection head and the sleeve is reduced; the fluctuation of the injection head during injection is reduced, and the incidence rate of low-speed change is reduced.
Drawings
Fig. 1 is a front view structure diagram of the sleeve of the present invention.
Fig. 2 is a right view structure diagram of the sleeve of the present invention.
Fig. 3 is a view showing the assembled structure of the sleeve and the shot-injecting head according to the present invention.
In the figure: 1. the sleeve comprises a sleeve positioning pin, 2, a sleeve, 3, a sleeve soup injection port, 4, an injection head lubricating threaded interface, 5, an injection head and sleeve fit clearance, 6, an injection head, 7, an injection rod, 8, an injection rod water pipe, 9, an injection head connecting rod, 10, a pressure chamber, 11, a sleeve positioning bolt, 12, a transverse sealing oil passage, 13, a longitudinal sealing oil passage, 14, an oil outlet, 15 and a sleeve.
Detailed Description
The utility model discloses a drift lubricating structure is as shown in fig. 1-3, sleeve 15 is outside through sleeve locating pin 1 and sleeve cover 11 fixed mounting sleeve cover 2, the sleeve 15 rear portion outside is equipped with sleeve notes hot water mouth 3, the inside cavity of sleeve 15 is for pressing the room 10, sleeve 15 root installation injection head 6, sleeve 15 root is equipped with interconnect vertically vertical seal oil duct 13 and transverse seal oil duct 12, oil-out 14 is connected to vertical seal oil duct 13 and transverse seal oil duct 12, 14 lower extremes of oil-out are located sleeve 15 medial surface, sleeve 15 rear end is equipped with injection head lubrication nipple 4 with injection head 6 junction, injection head lubrication nipple 4 is connected to vertical seal oil duct 13 and transverse seal oil duct 12. The rear part of the injection head 6 is provided with an injection rod 7, an injection head connecting rod 9 is arranged inside the injection head 6, and an injection rod water pipe 8 is arranged inside the injection head 6 and the injection rod 7 and penetrates through the injection head connecting rod 9.
In the die casting machine working process, the injection head 6 is before the work, lubricating oil can be through injection head lubricated hickey 4 and sealed oil circuit 12, 13 give injection head 6 and lubricate under pressure, lubricating oil is by oil-out 14, give injection head and the fit clearance 5 between the sleeve under pressure, trickling whole injection head 6, realize lubricating function, this lubricating mode is that pass through screwed joint 4 by oil pipe, the mode connect, can let the even parcel lubricating oil film of whole injection head, owing to be threaded connection, high-pressure lubricating oil can not cause the lubricating oil to splash and the loss of lubricating oil, thereby stable lubrication when having ensured injection head and sleeve cooperation.
