Abstract
The utility model relates to a double-chamber heat-preserving furnace of a low-pressure casting machine. The double-chamber heat-preserving furnace comprises two chambers: a working pressure chamber (3) and a liquid feeding chamber (1), channels (4) are arranged at the bottoms of the two chambers and are communicated with each other, a plug (4) is arranged on the channel at the bottom of the liquid feeding chamber (1), a cylinder (2) is arranged at the upper part of the liquid feeding chamber (1), the double-chamber heat-preserving furnace is characterized in that the cylinder (2) pushes the plug (4) to plug or open a channel opening of the liquid feeding chamber, so that the working pressure chamber (3) forms a sealed space so as to realize continuous low-pressure casting. With the structure, the heat-preserving furnace can not cause the defective goods as entrapped air and entrapped oxidized films are into a riser tube when a transfer pot feeds aluminum liquid into the heat-preserving furnace. In addition, the liquid feeding can not influence the work of the working pressure chamber, and the percent of pass of products can be improved.
Description
Technical field
The utility model belongs to automobile and motorcycle wheel hub Casting Equipment, especially a kind of two chambers holding furnace for air injection machine.
Background technology
Low pressure casting is generally adopted in the now wheel hub manufacturing of automobile industry, is comprised of holding furnace, mold machine table, control system etc.Aluminium liquid is added in the holding furnace sealing thermal insulation stove by transhipment pot.Control air pressure is pressed onto the aluminium liquid in the holding furnace on the board mould by stalk during work, can obtain qualified product according to specific pressurization, process for cooling.Because when aluminium liquid is added on the holding furnace by transhipment pot, aluminium liquid can be involved in air and oxide-film in stalk, gentle the steeping oneself-meeting of oxide-film that adds in the aluminium liquid in man-hour is forced in the mould, cause bad product, and when adding aluminium liquid to holding furnace, air injection machine must quit work, thereby causes mold cools down not reach operating temperature.The output of supposing each stove is 30, causes every stove that one to two bad product is arranged at the beginning because add aluminium liquid, 6% fraction defective namely, and 1,000,000 wheel hubs just have 60,000 defective products, and this all is a massive losses to any a company.
Summary of the invention
For above problem, the purpose of this utility model is to provide the two chambers of a kind of air injection machine holding furnace, that holding furnace is told two Room, middle link to each other and block and add liquid chamber and connect an end with stopping up head, stop up with air cylinder driven and control the circulation that adds liquid chamber and operating pressure chamber aluminium liquid and realize continuous low pressure casting.
The technical solution of the utility model is achieved in the following ways: the two chambers of air injection machine holding furnace, comprise two chambers, one is the operating pressure chamber, another is for adding liquid chamber, be provided with passage in the bottom of two Room and be interconnected, the described passage that adds the liquid chamber bottom is provided with the obstruction head, and the top that adds liquid chamber is provided with cylinder, it is characterized in that: described cylinder promotion obstruction head is blocked or is opened and adds the liquid chamber passway, and the operating pressure chamber forms a seal cavity and realizes continuous low pressure casting.
Described cylinder promotion obstruction head is blocked and is added the liquid chamber passway, adds liquid chamber and stops to add aluminium liquid, operating pressure chamber low pressure casting.
Described cylinder promotes to open the obstruction head, adds the liquid chamber passway and communicates with passway, operating pressure chamber, adds liquid chamber and adds aluminium liquid, and aluminium liquid flows to the operating pressure chamber, the uninterrupted low pressure casting in operating pressure chamber.
The utility model structure, the volume gas that causes in the time of can not adding aluminium liquid to holding furnace because of transhipment pot, volume oxide-film are in stalk and cause defective products.And do not affect the work of operating pressure chamber in the time of liquid feeding, not only improved the qualification rate of product, improved operating efficiency yet.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of prior art.
The specific embodiment
Known by Fig. 1, the two chambers of air injection machine holding furnace, comprise two two chambers, one is operating pressure chamber 3, and another is for adding liquid chamber 1, is provided with passage 4 in the bottom of two Room and is interconnected, the passage that adds liquid chamber 1 bottom is provided with and stops up 5, the top that adds liquid chamber is provided with cylinder 2, and cylinder 2 promotes to stop up 5 and blocks or open and add the liquid chamber passway, and operating pressure chamber 3 forms a seal cavity and realizes continuous low pressure casting.
Can add aluminium liquid to adding liquid chamber simultaneously in the process of casting, when operating pressure chamber aluminium liquid liquid level decline certain altitude, open the obstruction head that adds liquid chamber, the aluminium liquid that adds liquid chamber can flow to the operating pressure chamber because two Room liquid levels are poor, until two liquid levels are parallel.Stop up head and again block, can work again in the operating pressure chamber, and again add aluminium for adding liquid chamber, so circulation.
Being known by Fig. 2, is the structural representation of prior art.Operating room of holding furnace originally, control air pressure is pressed onto the aluminium liquid in the holding furnace on the board mould by stalk during work, because when aluminium liquid is added on the holding furnace by transhipment pot, aluminium liquid can be involved in air and oxide-film in stalk, gentle the steeping oneself-meeting of oxide-film that adds in the aluminium liquid in man-hour is forced in the mould, causes bad product, and when adding aluminium liquid to holding furnace, air injection machine must quit work, thereby causes mold cools down not reach operating temperature.
Claims (3)
1. the two chambers of air injection machine holding furnace, comprise two chambers, one is operating pressure chamber (3), another is for adding liquid chamber (1), be provided with passage (4) in the bottom of two Room and be interconnected, the described passage that adds liquid chamber (1) bottom is provided with and stops up head (4), the top that adds liquid chamber (1) is provided with cylinder (2), it is characterized in that: described cylinder (2) promotion obstruction head (4) is blocked or is opened and adds the liquid chamber passway, makes operating pressure chamber (3) form a seal cavity and realizes continuous low pressure casting.
2. cylinder according to claim 1 (2) promotion obstruction head (4) is blocked and is added the liquid chamber passway, adds liquid chamber (1) and stops to add aluminium liquid, operating pressure chamber (3) low pressure casting.
3. described cylinder (2) promotes to open and stops up head (1), adds the liquid chamber passway and communicates with passway, operating pressure chamber, adds liquid chamber (1) and adds aluminium liquid, and aluminium liquid flows to operating pressure chamber (3), operating pressure chamber (3) uninterrupted low pressure casting.
