Abstract
An ejection sleeve device comprises an ejection sleeve, a sleeve body arranged in the ejection sleeve in a sleeved mode, and a sleeve body base arranged under the sleeve body. An oil way is arranged in the sleeve body, an oil injection opening is formed in the oil way and located at the sleeve body base, and an oil outlet is formed in the oil way and located at the peripheral face, in contact with the ejection sleeve, of the sleeve body. The oil outlet of the oil way in the sleeve body of the ejection sleeve device is located at the peripheral face, in contact with the ejection sleeve, of the sleeve body, so that oil is directly pumped into the oil way at the oil injection opening of the oil way through a lubricating oil pump, lubricating oil flows to the position between the opposite peripheral faces of the sleeve body and the ejection sleeve from the oil outlet of the oil way through the oil way, oil injection is convenient and quick, workpieces are well lubricated and can not be damaged, and production efficiency is improved.
Description
Technical field
The utility model 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, between top cover and sleeve, can there is relative sliding, in order to reduce top cover and the sleeve relative friction forces when sliding, need to be to top cover and sleeve between side face, inject in opposite directions lubricating oil, on market, existing top cover device is when injecting lubricating oil, lubricating oil is to annotate into by the surface of top cover top product, but because the mobility of lubricating oil is poor, lubricating oil is difficult to flow in opposite directions between side face of top cover and sleeve, lubricant effect is bad, and the lubricating oil remaining in die cavity also can affect the quality of product.
Utility model content
The purpose of this utility model is in order to solve the existing defect of top cover device in prior art, a kind of oiling to be on time provided, convenient and swift, workpiece is obtained good lubricated and can not damage the top cover device of enhancing productivity.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of top cover device, comprise top cover, the sleeve base that is set in the sleeve in described top cover and is arranged on sleeve below, is provided with oil duct in described sleeve, 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 extends axially along described sleeve.
Above-mentioned a kind of top cover device, it is cylindric that described top cover and sleeve are all.
Above-mentioned a kind of top cover device, the below of described top cover is provided with collar flange.
The beneficial effects of the utility model are: 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 in opposite directions between side face of sleeve and top cover along oil duct from the oil-out of oil duct, oiling is convenient and swift, workpiece is obtained good lubricated and can not damage, improved production efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model
The specific embodiment
For making that architectural feature of the present utility model and the effect reached are had and further understand and be familiar with, in order to preferred embodiment and accompanying drawing, coordinate detailed explanation, be described as follows:
As shown in Figure 1, a kind of top cover device, comprise top cover 1, the sleeve base 3 that is set in the sleeve 2 in top cover 1 and is arranged on sleeve 2 belows, in sleeve 2, be provided with oil duct 4, this oil duct 4 is positioned at sleeve base 3 places 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 utility model, 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 extends axially along sleeve 2.
In the utility model, top cover 1 and sleeve 2 are all cylindric, and the below of top cover 1 is provided with collar flange 7, have strengthened the intensity of top cover 1.
Because the oil-out 6 of 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 pumps by lubricating oil oil pump (not shown) at pouring orifice 5 places of oil duct 4, lubricating oil flows out in opposite directions between side face of sleeve 2 and top cover 1 along oil duct from the oil-out 6 of oil duct, oiling is convenient and swift, workpiece is obtained good lubricated and can not damage, improved production efficiency.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what in above-described embodiment and description, describe is principle of the present utility model; under the prerequisite that does not depart from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall in claimed scope of the present utility model.The protection domain that the utility model requires is defined by appending claims and equivalent thereof.
