Abstract
The utility model relates to an oblique slide block mechanism for a sand core mold, which comprises an oblique slide block (1) and an oblique slide rod (2); a through hole (1.1) is formed in the oblique slide block (1); an upper rolling shaft (3) and a lower rolling shaft (4) are arranged in the through hole (1.1); and the oblique slide block (1) is in sliding fit between the upper rolling shaft (3) and the lower rolling shaft (4). The oblique slide block mechanism for the sand core mold has the beneficial effect that the surface abrasion of the oblique slide rod can be reduced.
Description
Technical field
The utility model relates to mould, relates to or rather a kind of core mould Slanted slide block mechanism.
Background technology
Core mould Slanted slide block mechanism comprises angled-lift splits and oblique slide bar.Described angled-lift splits is provided with the inclined hole that size and dimension and described oblique slide bar match.Described oblique slide bar is connected with patrix, and described oblique slide bar is slidingly fitted in the described inclined hole, tiltedly between slide bar and the inclined hole for face contact, the motion of oblique slide bar can be with the movable slider slip.Because working environment medium sand and the dust of core mould are many, tiltedly can advance sand grains and dust unavoidably between slide bar and the inclined hole, slide back and forth, tiltedly slide bar surface and inclined hole sidewall are worn easily, time has been grown, tiltedly the spacing between slide bar and the inclined hole will be larger, thereby can affect the precision of product, causes the service life of core mould shorter.
The utility model content
The technical problems to be solved in the utility model is that a kind of core mould Slanted slide block mechanism that can reduce the wearing and tearing on oblique slide bar surface is provided.
Technical solution of the present utility model is, a kind of core mould Slanted slide block mechanism with following structure is provided, and comprises angled-lift splits and oblique slide bar; Described angled-lift splits is provided with through hole; Be provided with roller bearing and lower roller bearing in the described through hole; Described oblique slide bar is slidingly fitted between described upper roller bearing and the lower roller bearing.
After adopting above structure, core mould Slanted slide block mechanism of the present utility model compared with prior art, has the following advantages:
Owing to be provided with roller bearing and lower roller bearing in the through hole of core mould Slanted slide block mechanism of the present utility model; tiltedly slide bar is slidingly fitted between roller bearing and the lower roller bearing; tiltedly contact for line between slide bar and upper roller bearing and the lower roller bearing; even have sand grains or dust between upper roller bearing and the lower roller bearing; surface abrasion to oblique slide bar is also smaller, can prolong the service life of core mould.
As a kind of improvement of the present utility model, described upper roller bearing comprises Upper shaft sleeve and upper axis, and described upper axis is fixed in the described through hole, and described Upper shaft sleeve can be outside upper axis circumferentially be linked in described upper axis rotationally.Structure is simpler.
As another kind of improvement the of the present utility model, described lower roller bearing comprises Lower shaft sleeve and lower axis, and described lower axis is fixed in the described through hole, and described Lower shaft sleeve can be outside lower axis circumferentially be linked in described lower axis rotationally.Structure is simpler.
Also have a kind of improvement as of the present utility model, described upper axis is bolted in the described through hole, and described lower axis is bolted in the described through hole.After adopting this kind structure, be convenient for changing Upper shaft sleeve and Lower shaft sleeve.
Description of drawings
Fig. 1 is the structural representation of core mould Slanted slide block mechanism of the present utility model.
Fig. 2 is the structural representation that core mould Slanted slide block mechanism of the present utility model is not installed oblique slide bar.
Shown in the figure: 1, angled-lift splits, 1.1, through hole, 2, oblique slide bar, 3, upper roller bearing, 3.1, Upper shaft sleeve, 3.2, upper axis, 4, lower roller bearing, 4.1, Lower shaft sleeve, 4.2, lower axis.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
See also illustrated in figures 1 and 2ly, core mould Slanted slide block mechanism of the present utility model comprises angled-lift splits 1 and oblique slide bar 2.During concrete the application, described oblique slide bar 2 can be connected with patrix.Described angled-lift splits 1 is provided with through hole 1.1.Be provided with roller bearing 3 and lower roller bearing 4 in the described through hole 1.1, described oblique slide bar 2 is slidingly fitted between described upper roller bearing 3 and the lower roller bearing 4, when oblique slide bar 2 slides between upper roller bearing 3 and lower roller bearing 4 back and forth, can drive angled-lift splits 1 and slide like this.
Described upper roller bearing 3 comprises Upper shaft sleeve 3.1 and upper axis 3.2, and described upper axis 3.2 is fixed in the described through hole 1.1, and described Upper shaft sleeve 3.1 can be outside upper axis 3.2 circumferentially be linked in described upper axis 3.2 rotationally.In this specific embodiment, described upper axis 3.2 is bolted in the described through hole 1.1, an end of namely going up axis is provided with limited cap, be equipped with through hole on the two side of through hole, the limited cap of upper axis is spacing in the through hole of through hole one side, upper axis is provided with bolt hole away from an end of limited cap, and bolt screws in the bolt hole of upper axis by the through hole of through hole opposite side.
Described lower roller bearing 4 comprises Lower shaft sleeve 4.1 and lower axis 4.2, and described lower axis 4.2 is fixed in the described through hole 1.1, and described Lower shaft sleeve 4.1 can be outside lower axis 4.2 circumferentially be linked in described lower axis 4.2 rotationally.In this specific embodiment, described lower axis 4.2 is bolted in the described through hole 1.1, namely descend an end of axis to be provided with limited cap, be equipped with through hole on the two side of through hole, the limited cap of lower axis is spacing in the through hole of through hole one side, lower axis is provided with bolt hole away from an end of limited cap, and bolt screws in the bolt hole of lower axis by the through hole of through hole opposite side.
