Abstract
The utility model relates to an easy-to-cut sheet of a riser. The easy-to-cut sheet comprises an easy-to-cut sheet body which is shaped like a sheet; a liquid through hole longitudinally passing through the easy-to-cut sheet body is formed in the center of the easy-to-cut sheet body; the liquid through hole is of a frustum-shaped hole with a small upper part and a big lower part; a circle of circular rings with circular arc-shaped cross sections are molded around the liquid through hole in the upper surface of the easy-to-cut sheet body; the inner circle diameter of each circular ring is equal to the upper opening diameter of the liquid through hole; and the inner ring of each circular ring is mutually abutted with the upper opening of the liquid through hole. A circular through hole which is waisted and is communicated up and down is formed in the upper opening of the liquid through hole through the combination of the frustum-shaped liquid through hole and the circular arc-shaped circular holes, so that a casting riser can be separated from a casting body under the action of stress only by knocking the riser after the finish of the casting. Thus, the easy-to-cut sheet is very convenient; and the casting body is prevented from being damaged.
Description
technical field:
The utility model relates to casting field, particularly a kind of riser pad.
background technology:
At present, in Foundry Production, for fear of foundry goods, occur defect, generally all above foundry goods die cavity, be provided with rising head, and in order to facilitate the separated of casting pressing port and foundry goods body, rising head lower end is generally also provided with riser pad.
Granted publication number is CN102328030B, the patent of invention file that name is called " riser pad " discloses a kind of riser pad, its liquid-through hole comprise large mouthful upper upper liquid-through hole and large mouthful under lower liquid-through hole, the cross-sectional outling of upper liquid-through hole and lower liquid-through hole is four jiaos or five jiaos or hexagram, and the osculum of the osculum of upper liquid-through hole and lower liquid-through hole congruence is docking mutually also, between upper liquid-through hole and the osculum of lower liquid-through hole, be provided with the middle excessively hole of polygonal star cylindricality of the osculum congruence of section and upper and lower liquid-through hole.The minimum cross section of this patent casting pressing port has been left foundry goods body surface, be conducive to improve the problem that traditional cameron core casting pressing port easily injures foundry goods body when separated with foundry goods body, but because this riser pad is complex-shaped, in manufacture, there is certain difficulty, and the cross-sectional outling of liquid-through hole is multi-corner star-shape, while making casting pressing port separated with foundry goods body, need to find interior angle position could realize eaily separation.
utility model content:
The purpose of this utility model is exactly the deficiency for prior art, and a kind of riser pad is provided, and has well solved problems such as manufacturing easy, casting pressing port existence inconvenience separated with foundry goods body.
Technology solution of the present utility model is as follows:
Riser pad, comprise the cameron core body that is sheet shape, described cameron core body center offers the liquid-through hole of longitudinal perforation cameron core body, described liquid-through hole is up-small and down-big truncated cone-shaped hole, the liquid-through hole position of described cameron core body upper surface also forms the annulus that a circle cross section is circular arc around, the interior circular diameter of described annulus equates with the back cut diameter of liquid-through hole, and the interior ring of annulus and suitable for reading mutual docking of liquid-through hole.By the combination of the liquid-through hole of truncated cone-shaped and the annulus of circular arc; make the utility model at liquid-through hole position of upper place, form the manhole being communicated with up and down of a closing waist shape; make to have cast between rear casting pressing port and foundry goods body; only need to knock rising head just can utilize stress that casting pressing port is separated with foundry goods body; very convenient; more protected foundry goods body not impaired; and the utility model shape is very simple; only just on the cameron core body of sheet shape, the annulus that cross section is circular arc is enclosed in moulding one, manufactures very convenient.
As preferably, the thickness of annulus is consistent with cameron core body thickness.The uniformity that guarantees to connect up and down thickness, makes casting pressing port separated with foundry goods body more light.
As preferably, cameron core body is disc.
As preferably, the lower base angle of liquid-through hole is 30 °～55 °.
The beneficial effects of the utility model are:
1, the utility model is by the combination of the liquid-through hole of truncated cone-shaped and the annulus of circular arc, make the utility model at liquid-through hole position of upper place, form the manhole being communicated with up and down of a closing waist shape, make to have cast between rear casting pressing port and foundry goods body, only need to knock rising head just can utilize stress that casting pressing port is separated with foundry goods body, very convenient, more protected foundry goods body not impaired, and the utility model shape is very simple, only just on the cameron core body of sheet shape, the annulus that cross section is circular arc is enclosed in moulding one, manufacture very convenient,
2, the thickness of annulus of the present utility model is consistent with cameron core body thickness, guarantees to connect up and down the uniformity of thickness, makes casting pressing port separated with foundry goods body more light.
accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is home position longitudinal sectional view of the present utility model;
In figure: cameron core body 1; Liquid-through hole 2; Annulus 3.
the specific embodiment:
Embodiment: riser pad as shown in Figure 1 and Figure 2, comprise the cameron core body 1 that is sheet shape, cameron core body 1 center offers the liquid-through hole 2 of longitudinal perforation cameron core body, liquid-through hole 2 is up-small and down-big truncated cone-shaped hole, liquid-through hole 2 positions of cameron core body 1 upper surface also form the annulus 3 that a circle cross section is circular arc around, the interior circular diameter of annulus 3 equates with the back cut diameter of liquid-through hole 2, and the interior ring of annulus 3 and suitable for reading mutual docking of liquid-through hole 2.
The thickness of annulus 2 and cameron core body 1 consistency of thickness.
Cameron core body 1 is disc.
The lower base angle of liquid-through hole 3 is 45 °.
The foregoing is only preferred embodiment of the present utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all should belong to the scope of the utility model protection.
