Abstract
The utility model discloses a mould guide column for manufacturing a plastic upper cover of a display. The mould guide column comprises a column body arranged in an upper mould and a lower mould of a mould in a communicated way, wherein the column body is a cylinder; inclined annular oil tanks for filling lubricating oil are arranged on the circumferential side surface of the cylinder; the inclined angles of the inclined annular oil tanks can be 5-30 degrees; and further, the five inclined annular oil tanks with the inclined angles of 20 degrees are arranged on the circumferential side of the cylinder in a way that the inclined annular oil tanks are parallel to each other and have the same spacing distance. According to the mould guide column, the original horizontal annular oil tanks are changed, the problems that the guide column cannot move up and down, easily generates heat and is easy to wear due to the limited lubricating area of the lubricating oil filled in the guide column and also easily causes stress concentration at the horizontal planes of the oil tanks at the same time are flexibly, simply and effectively solved, the lubricating area is increased, the lubricating performance is improved, and the problem of stress concentration is solved at the same time.
Description
Technical field
The utility model relates to a kind of mold parts, especially for the guide-post of die-set of making the display upper plastic cover.
Background technology
At present, the guide pillar that adopts in the mould of making the display upper plastic cover is the guide pillar with horizontal endless oil groove, the oil lubrication area is limited, can't run up and down, and easily heating wearing and tearing, also easily produce the problem that stress is concentrated at the horizontal plane place that is offering oil groove simultaneously, the intensity of guide pillar is had larger impact.
Therefore, need exploitation badly and a kind ofly can overcome defects, can in guide pillar, run up and down to realize lubricating oil, improve its lubricated area and greasy property, overcome simultaneously the guide-post of die-set for the manufacture of the display upper plastic cover of problem of stress concentration.
The utility model content
The purpose of this utility model proposes a kind ofly can overcome defects exactly, satisfies and improves its lubricated area and greasy property, overcomes simultaneously the guide-post of die-set for the manufacture of the display upper plastic cover of problem of stress concentration.
The utility model is to solve the problems of the technologies described above a kind of guide-post of die-set for the manufacture of the display upper plastic cover of the technical scheme that adopts, comprise that conducting is arranged on the cylinder in the upper die and lower die of mould, described cylinder is cylinder, and described cylindrical circumference side is provided with the oblique endless oil groove for charging-up lubricant oil.
Better, described oblique endless oil groove angle of inclination is 5-30 °.
Better, the circumference of described cylinder is parallel to each other, neighbor distance equates is provided with the oblique endless oil groove that 5 angles of inclination are 20 °.
In sum, as seen the utility model has changed original horizontally disposed annular oil groove, and flexible, simple and effective to have overcome the lubricated area of guide pillar charging-up lubricant oil limited, can't run up and down, and easily heating wearing and tearing also easily produce the problem that stress is concentrated at the horizontal plane place that offers oil groove simultaneously.The endless oil groove that is in tilted layout has realized that the lubricating oil in the endless oil groove also can run up and down, and lubricity is good; Evenly be arranged in parallel and realized further that then integrated stress is evenly distributed, lower greatly and offer oil groove to the intensity effect of guide pillar; The utility model by above technological improvement after so that make the location and precision also relative raising of the mould of display upper plastic cover, increased the life-span of mould.
Description of drawings
Fig. 1 is the structural representation of a specific embodiment of the present utility model.
Fig. 2 is the application schematic diagram of this specific embodiment.
The specific embodiment
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
As depicted in figs. 1 and 2, a kind of guide-post of die-set for the manufacture of the display upper plastic cover of the present embodiment, comprise that conducting is arranged on the patrix 1 of mould and the cylinder 3 in the counterdie 2, cylinder 3 is cylinder, and described cylindrical circumference side is provided with the oblique endless oil groove 4 for charging-up lubricant oil.
Further embodiment as the present embodiment, the circumference of cylinder 3 is parallel to each other, neighbor distance equates is provided with the oblique endless oil groove 4 that 5 tilt angle alpha are 20 °, certainly, in other embodiments tiltedly endless oil groove 4 tilt angle alpha can also be other angles such as 5 ° or 8 ° or 30 °; Tiltedly the quantity of endless oil groove also can be adaptive according to length or the mould needs of cylinder.
The above only is preferred embodiment of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
