Abstract
The utility model discloses a combined pouring flange sand core for a valve body. The combined pouring flange sand core comprises a flange sand core body, wherein two eudipleural positioning convex sand columns are arranged on one side of the flange sand core body; and a plurality of flange convex column sand cores are arranged on the other side of the flange sand core body. The combined pouring flange sand core is easily placed in a combined pouring valve body mold cavity of precoated sand and can be accurately positioned; the flange sand core body is thinner, so that the strength requirement can be met and the precoated sand can be saved; the two eudipleural positioning convex sand columns are used for fixing the flange sand core in the combined mold cavity of the precoated sand; the flange convex column sand cores are used for forming the flange bolt holes of the finished valve body; the center positioning is accurate; the distribution is uniform; the aperture size is accurate; the bolt holes are formed by pouring in one step without machining; the production efficiency and the product quality are effectively improved; and the combined pouring flange sand core is easy to realize and has a good application prospect.
Description
Technical field
The utility model relates to the valve body casting technology field, is specifically related to a kind of composite pouring flange core for valve body.
Background technology
Flange core of the prior art is thicker, and waste precoated sand raw material put into that to cover sand composite pouring valve body die cavity stationarity poor, locate not precisely, influences product quality, and the flange of casting needs secondary operations formation bolt hole, and production efficiency is low.
The utility model content
The technical problem that the utility model solves is that to overcome in the prior art flange core thicker, and stationarity is poor, locate not accurate, the problem that production efficiency is low.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of composite pouring flange core for valve body comprises flange core body, and a side of described flange core body has two protruding sand posts in symmetrical location, and the opposite side of flange core body is provided with several flange projection cores.
Aforesaid a kind of composite pouring flange core for valve body, it is characterized in that: described flange core body thickness is 10-14 mm.
Aforesaid a kind of composite pouring flange core for valve body is characterized in that: the quantity of described flange projection core is 4-8.
The beneficial effects of the utility model are: the composite pouring flange core that is used for valve body that the utility model provides, be easy to put into and cover sand composite pouring valve body die cavity and accurate positioning, flange core body is thinner, can satisfy requirement of strength, can save the precoated sand raw material again, two protruding sand posts in symmetrical location can play the effect of mounting flange core in covering sand combination die cavity, flange projection core is used to form valve body finished product flange bolt hole, centralized positioning is accurate, be evenly distributed, aperture size is accurate, and the bolt hole once-cast is shaped, need not machining, improved production efficiency and product quality effectively, realized easily, had a good application prospect.
Description of drawings
Fig. 1 is the schematic diagram of the composite pouring flange core for valve body of the present utility model.
Fig. 2 is the profile one of the composite pouring flange core for valve body of the present utility model.
Fig. 3 is the profile two of the composite pouring flange core for valve body of the present utility model.
The implication of mark is as follows in the accompanying drawing:
1: flange core body; 2: flange projection core; 3: locate protruding sand post.
The specific embodiment
Below in conjunction with Figure of description, the utility model is further described.
As Fig. 1, Fig. 2 and shown in Figure 3, a kind of composite pouring flange core for valve body, comprise flange core body 1, flange core body 1 is thinner, thickness is 10-14 mm, can satisfy requirement of strength, can save the precoated sand raw material again, a side of flange core body 1 has two protruding sand posts 3 in symmetrical location, in covering sand combination die cavity, can play the effect of mounting flange core, flange core body opposite side in 1 morning is provided with 4-8 flange projection core 2, can decide according to the difference of valve flange bolt hole, and flange projection core 2 is used to form valve body finished product flange bolt hole, centralized positioning is accurate, be evenly distributed, aperture size is accurate, and the bolt hole once-cast is shaped, need not machining, improved production efficiency and product quality effectively, realized easily, had a good application prospect.
More than show and described basic principle of the present utility model, principal character and advantage.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away 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 the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
