Abstract
The invention discloses a hot core box die for three-way valve body casting.The hot core box die comprises a die body, the die body is provided with a cavity matched with a to-be-manufactured die core in shape, and at least one pressing groove indented to the cavity is formed in the bottom of the die body so that at least one reinforcing rib can be formed on the die core.The hot core box die is provided with the pressing grooves, so that the reinforcing ribs are formed on the manufactured die core, the overall strength of the die core is greatly improved, the die core does not deform during pouring, size stability of products is high, and the water sealing effect of a sealing face is good.The reinforcing ribs are formed in an indented mode so that sand can be saved and cost can be reduced.Exhaust is facilitated, and the quality of cast products of a three-way valve body is guaranteed.
Description
Technical field
The present invention relates to a kind of three-way valve body mold for forming, be specially a kind of for making three-way valve body sand casting time core used hot core box mould.
Background technology
Three-way valve is widely used in the fields such as oil, chemical industry, natural gas, power station, metallurgy；Main medium has all kinds such as water, steam, oil product, gas, mud, various Korrosionsmedium, liquid metal and radioactive fluid fluidly to flow；The operating pressure of valve can supertension from 0.0013MPa to 1000MPa, operating temperature is from the ultralow temperature of-269 DEG C to the high temperature of 1430 DEG C, especially at oil, chemical field, environment owing to using is more special, the three-way valve used to have the technology requirements such as high temperature resistant, corrosion-resistant, intensity big, good airproof performance, so the manufacture of three-way valve has also just been had significantly high technology requirement.
The mode of current general sand casting makes three-way valve, and the concrete structure of three-way valve body is as shown in Figure 1.When the mode utilizing sand casting makes, valve body profile portion utilizes green sand to carry out moulding, body cavity part then needs to be placed in sand mold by core after mould assembling integrated poured obtained by molding.After current hot core box mould structure fabrication precoated sand core out puts into the cooling of die cavity moulding by casting, the inner chamber Sealing Surface size less stable of foundry goods, consistent, during fashion bad, after spool puts down from top to bottom, inspection often occurs that spool is put not in place or Sealing Surface and opened the phenomenon that grade size is bigger than normal or less than normal；Pressure testing water leakage situation often occurs, cause triple-valve body poor sealing, do not meet technology requirement, thus causing that product quality is uneven, and moulding efficiency is low, moulding labor cost high, virtually add more production cost, conforming product rate hardly results in guarantee.
Summary of the invention
In order to solve above technical problem, the present invention provides a kind of three-way valve body hot core box for casting mould, when its made core bulk strength increase, cast, core size distortion is little, cool down rear valve body inner chamber dimensionally stable, the castability of three-way valve body, improving product qualification rate can be effectively improved.
The present invention is achieved by the following technical solutions:
A kind of three-way valve body hot core box for casting mould, including die ontology, described die ontology is provided with the cavity mated with the core shape to make, and the bottom of die ontology is provided with at least one to the recessed indent of cavity so that core forms at least one reinforcement.
As preferred embodiment, the quantity of described indent is two, and two indents are arranged in parallel.
As preferred embodiment, the position of described reinforcement is corresponding with the position of three-way valve body Sealing Surface.
The invention has the beneficial effects as follows: the hot core box mould of the present invention is provided with indent so that the core made is formed with reinforcement, the bulk strength of core is greatly increased so that core will not deform when cast, and product size stability is high, and sealing surface water sealing effect is good；Reinforcement utilizes recessed mode to be formed, it is possible to economize on sand, reduces cost, and is conducive to aerofluxus, it is ensured that the cast article quality of three-way valve body.
Accompanying drawing explanation
Fig. 1 is the structure chart of three-way valve body；
Fig. 2 is the side view of the present invention；
Fig. 3 is the top view of the present invention.
Symbol description: 1-die ontology, 2-cavity, 3-indent.
Detailed description of the invention
The invention will be further described with reference to the accompanying drawings and in conjunction with the embodiments.
Precoated sand, for making core used during three-way valve body sand casting, time specifically used, is placed in hot core box mould by the hot core box mould of the present invention, core can be made fixed-type by heating.
Concrete as in figure 2 it is shown, the die ontology 1 of hot core box mould is provided with the cavity 2 mated with the core shape to make, the bottom of die ontology 1 is provided with at least one to the recessed indent 3 of cavity 2 so that core forms at least one reinforcement.In the present embodiment, the quantity of indent 3 is set to two, and two indents 3 are arranged in parallel.The position of reinforcement made on core is corresponding with the position of three-way valve body Sealing Surface.
Based on said structure, the core made by the present invention is owing to being provided with reinforcement, and therefore its intensity is greatly increased, and it will not deform when cast.The present invention, when not changing sand mold, by the setting of reinforcement, improves bulk strength, reduces cost, saved man-hour, and yardstick is more accurate, it is ensured that product quality, and conforming product rate is protected, and substantially increases production efficiency.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.All within the spirit and principles in the present invention, any amendment of making, equivalent replacement, improvement etc., should be included within protection scope of the present invention.
