Abstract
The utility model discloses a combined gate valve body casting mould. The combined gate valve body casting mould comprises a structure mould for forming the outer shape of a gate valve body, a core box mould for forming an inner cavity of the gate valve body, and two flange sand core moulds for forming flange bolt holes, wherein the structure mould comprises an outer upper valve body shell flange sand core mould and an outer lower valve body shell flange sand core mould; the outer upper valve body shell flange sand core mould and the outer lower valve body shell flange sand core mould are clamped together to form an accommodating cavity for accommodating the core box mould and the flange sand core moulds; the core box mould is reverse T-shaped; and the flange sand core moulds are nested on the two sides of the horizontal side of the core box mould respectively. A pair of flange sand core moulds, forming protruding post structures of the flange bolt holes, are nested in the core box mould, and the produced gate valve body and the flange bolt holes are moulded at one step, so that the manufacturing precision of the flange bolt holes is improved, the production cost is saved and the manufacturing process is simplified; and the combined gate valve body casting mould is convenient to assemble and has a good application prospect.
Description
Technical field
The utility model relates to valve body placing field, is specifically related to a kind of casting mold of combined type brake valve body.
Background technology
At present, brake valve body as shown in Figures 1 and 2 adopts universal mold to pour into a mould, universal mold comprises structure mold, the secondary core box mould that forms the brake valve body inner chamber with a secondary formation brake valve body external form, the structure mold of brake valve body forms the exterior contour of valve body, and the core box mould of brake valve body becomes the inner chamber of brake valve body, yet, there is not bolt hole on the brake valve body casting finished products flange of making like this, these bolts hole need be got out, not only influence production capacity, the precision in flange bolt hole can't guarantee simultaneously.
The utility model content
Technical problem to be solved in the utility model is, at the deficiencies in the prior art, a kind of casting mold of combined type brake valve body is provided, combination by structure mold, core box mould and flange core mold, product quality and the production efficiency of brake valve body have been improved, saved production cost, simplified the manufacturing process to brake valve body, had a good application prospect.
In order to achieve the above object, the technical scheme that adopts of the utility model is:
A kind of casting mold of combined type brake valve body, it is characterized in that: comprise the structure mold that forms the brake valve body external form, form core box mould and two flange core mold that form the flange bolt hole of brake valve body inner chamber, described structure mold comprises the outer upper casing flange core mold of valve body and the outer lower casing flange core mold of valve body, the outer upper casing flange core mold of described valve body and the outer lower casing flange core mold of valve body are fastened togather and form the placed cavity of placing core box mould and flange core mold, described core box mould becomes the inverted T-shape shape, and described flange core mold is nested in the both sides on core box die horizontal limit respectively.
The casting mold of aforesaid a kind of combined type brake valve body is characterized in that: described structure mold, core box mould and flange core mold all adopt the wear-resistant aluminum alloy material to make.
The casting mold of aforesaid a kind of combined type brake valve body is characterized in that: the outer upper casing flange core mold of described valve body is in the same place by adopting bolting with the outer lower casing flange core mold of valve body.
The beneficial effects of the utility model are: the combined type valve body casting mold that the utility model provides, the embedded secondary flange core mold that forms flange bolt hole convex cylinder that is with on the core box mould, combination by structure mold, core box mould and flange core mold, the brake valve body of producing, flange bolt hole once-forming has improved the flange bolt hole accuracy of manufacture, saved production cost, simplified manufacturing process, and casting mold is easy to assembly, has a good application prospect.
