Abstract
The invention provides a propping sleeve device. The device comprises a propping sleeve, a sleeve which is arranged in the propping sleeve by a sleeving manner, and a sleeve base which is arranged below the sleeve; an oil channel is arranged in the sleeve, wherein the oil channel is characterized in that an oil inlet is arranged in the sleeve base, and oil outlets are arranged in the circumference in which the sleeve is contacted with the propping sleeve. According to the propping sleeve device, the oil outlets of the oil channel in the sleeve are positioned in the circumference in which the sleeve is contacted with the propping sleeve, oil is directly pumped to the oil channel by a lubricating oil pump through the oil inlet of the oil channel, and the lubricating oil flows out through the oil outlets of the oil channel along the oil channel until reaching the opposite circumferences of the sleeve and the propping sleeve; therefore, the oil is conveniently and quickly poured, a tool can be lubricated well and avoided damage, and as a result, the production efficiency is improved.
Description
Technical field
The present invention relates to Die-casting Machines field, especially a kind of top cover device.
Background technology
In the use procedure of top cover device, top cover is when ejecting product, relative sliding can be there is between top cover and sleeve, in order to reduce top cover and the relative friction forces of sleeve when sliding, need to inject lubricating oil between side face in opposite directions to top cover and sleeve, on market, existing top cover device is when injecting lubricating oil, lubricating oil is entered by the surface filling of product above top cover, but because the mobility of lubricating oil is poor, lubricating oil is difficult to flow into top cover and in opposite directions between side face of sleeve, lubricant effect is bad, and the lubricating oil remained in die cavity also can affect the quality of product.
Summary of the invention
The object of the invention is the defect in order to solve in prior art existing for top cover device, provide one can oiling on time, convenient and swift, make workpiece obtain good lubrication and can not damage, the top cover device of enhancing productivity.
To achieve these goals, the technical solution used in the present invention is:
A kind of top cover device, comprise top cover, be set in the sleeve in described top cover and be arranged on the sleeve base below sleeve, in described sleeve, be provided with oil duct, this oil duct is positioned at described sleeve base position and is provided with pouring orifice, and oil duct is positioned at the side face place that described sleeve and top cover contact and is provided with oil-out.
Above-mentioned a kind of top cover device, described pouring orifice place is provided with screw thread.
Above-mentioned a kind of top cover device, described oil duct is along described quill to extension.
Above-mentioned a kind of top cover device, described top cover and sleeve are all cylindrically.
Above-mentioned a kind of top cover device, the below of described top cover is provided with collar flange.
Beneficial effect of the present invention is: the oil-out of the sleeve internal oil channel of this top cover device is positioned at the side face place that sleeve and top cover contact, directly oily to oil duct pump by lubricating oil oil pump at the pouring orifice place of oil duct, lubricating oil flows out to sleeve and in opposite directions between side face of top cover along oil duct from the oil-out of oil duct, oiling is convenient and swift, make workpiece obtain good lubrication and can not damage, improve production efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention
Detailed description of the invention
Further understand for making to have architectural feature of the present invention and effect of reaching and be familiar with, coordinate detailed description in order to preferred embodiment and accompanying drawing, be described as follows:
As shown in Figure 1, a kind of top cover device, comprise top cover 1, the sleeve base 3 being set in the sleeve 2 in top cover 1 and being arranged on below sleeve 2, oil duct 4 is provided with in sleeve 2, this oil duct 4 is positioned at sleeve base 3 place and is provided with pouring orifice 5, and oil duct 4 is positioned at the side face place that sleeve 2 and top cover 1 contact and is provided with oil-out 6.
In the present invention, the bore of pouring orifice 5 is greater than the bore of oil duct 4, and at pouring orifice, place is provided with screw thread, the oiling device of outside by with being threaded of pouring orifice place, be convenient to inject lubricating oil in oil duct, oil duct 4 axially extends along sleeve 2.
In the present invention, all cylindrically, the below of top cover 1 is provided with collar flange 7, strengthens the intensity of top cover 1 for top cover 1 and sleeve 2.
Oil-out 6 due to the sleeve internal oil channel 4 of this top cover device is positioned at the side face place that sleeve 2 and top cover 1 contact, directly oily to oil duct 4 pump by lubricating oil oil pump (not shown) at pouring orifice 5 place of oil duct 4, lubricating oil flows out to sleeve 2 and in opposite directions between side face of top cover 1 along oil duct from the oil-out 6 of oil duct, oiling is convenient and swift, make workpiece obtain good lubrication and can not damage, improve production efficiency.
More than show and describe general principle of the present invention, principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; the just principle of the present invention described in above-described embodiment and description; the present invention also has various changes and modifications without departing from the spirit and scope of the present invention, and these changes and improvements all fall in claimed scope of the present invention.The protection domain of application claims is defined by appending claims and equivalent thereof.
