Abstract
The utility model discloses a liquid-lifting pipe joint position structure of a low-pressure casting liquid-lifting system, comprising a liquid-lifting tank, a liquid-lifting pipe pressing plate, a liquid-lifting pipe and a liquid-lifting pipe seat plate, wherein the liquid-lifting pipe pressing plate is arranged below a liquid-lifting port of the liquid-lifting tank; and the liquid-lifting pipe and the liquid-lifting pipe seat plate are arranged below the liquid-lifting pipe pressing plate in parallel. The liquid-lifting pipe joint position structure is characterized in that the liquid-lifting port of the liquid-lifting tank is provided with a ring-shaped and downward-extending part; the end surface of the extending part is directly contacted with the upper end surface of the liquid-lifting pipe; and the liquid-lifting pipe pressing plate is sheathed on the outer ring of the extending part. Compared with the prior art, as the liquid-lifting port of the liquid-lifting tank is provided with the ring-shaped and downward-extending part, and the liquid-lifting pipe pressing plate is sheathed on the outer ring of the extending part, the liquid-lifting pipe joint position structure avoids that the metal liquid-lifting pipe pressing plate is directly contacted with aluminium liquid, thus avoiding the blockage caused by oxidation reactants generated by the reaction between the liquid-lifting pipe pressing plate and the aluminium liquid, and guaranteeing smoothness of a liquid-lifting channel. After the technical scheme is adopted, the clearing time of the liquid-lifting channel only needs 10-20 minutes, so the production efficiency is greatly improved.
Description
Technical field
The utility model relates to a kind of low pressure casting and rises liquid systems, and particularly a kind of low pressure casting rises liquid systems stalk joint structure.
Background technology
Low pressure casting is a kind of new Special Processes of Metal Castings technology, rises liquid systems and be the important component part in the low pressure casting system, and it all plays a part decision to the rise shape of the speed of (filling type) and stream strand of molten metal.
Existing a kind of low pressure casting rises in the liquid systems, its stalk and the structure that rises the liquid pool junction are as shown in Figure 1, comprise rise liquid pool 1 ', be arranged at the stalk pressing plate 2 that rises liquid pool 1 ' rise liquid mouth below ', the parallel stalk 3 that is arranged at stalk pressing plate 2 ' below ' and stalk seat board 4 ', wherein, rising liquid pool 2 ' rise liquid mouth inner ring, stalk pressing plate 2 ' inner ring and stalk 3 ' inner ring is to link to each other successively to be provided with.This existing structure, when casting aluminium liquid is through the stalk joint in the course of work, aluminium liquid can directly contact with metallic stalk pressing plate, and then producing reaction, the oxide of generation usually is deposited in the pressing plate inner ring, has influenced to rise the unobstructed of liquid passage, even result in blockage, this tamper is also cumbersome in when cleaning, and generally clearance time needs 30-50 just can make to rise the liquid routing restoration unimpeded, has so just caused the low defective of production efficiency.
The utility model content
Technical problem to be solved in the utility model is, in order to overcome above-mentioned the deficiencies in the prior art, ensure that to rise the liquid passage unimpeded and provide a kind of, the low pressure casting that reduces its clearance time rises liquid systems stalk joint structure, makes low pressure casting rise liquid systems production efficiency and is improved.
In order to solve the problems of the technologies described above, adopted following technical scheme in the utility model:
A kind of low pressure casting rises liquid systems stalk joint structure, comprise and rise liquid pool, be arranged at the stalk pressing plate that rises liquid pool and rise liquid mouth below, parallel stalk and the stalk seat board that is arranged at stalk pressing plate below, its characteristics are, the described liquid pool that rises rises liquid mouth place and has an extension that annular is downward, described extension end face directly contacts with the stalk upper surface, and described stalk pressing plate is set on the extension outer ring.
Compare with prior art, creatively will rise liquid pool in the utility model rises liquid mouth place a downward annular extension is set, the extension end face is directly contacted with the stalk upper surface, the stalk pressing plate then is set on the extension outer ring, so promptly under the situation that does not influence stalk pressing plate function, avoided metallic stalk pressing plate directly to contact, resulted in blockage, guaranteed to rise the unimpeded of liquid passage thereby avoided stalk pressing plate and aluminium liquid to produce reaction generation oxidation reactant with aluminium liquid.After adopting the technical program, cleaning rises the liquid channel time only needs the 10-20 branch, has improved production efficiency greatly.
Description of drawings
Fig. 1 is the structural representation that existing low pressure casting rises liquid systems stalk joint structure.
Fig. 2 is a structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
During concrete enforcement, as shown in Figure 2, a kind of low pressure casting rises liquid systems stalk joint structure, comprise and rise liquid pool 1, be arranged at the stalk pressing plate 2 that rises 1 liter of liquid mouth below of liquid pool, parallel stalk 3 and the stalk seat board 4 that is arranged at stalk pressing plate 2 belows, wherein, the described liquid pool that rises rises liquid mouth place and has an extension 5 that annular is downward, described extension 5 end faces directly contact with stalk 3 upper surfaces, described stalk pressing plate 2 fixed covers are located on extension 5 outer rings, stalk pressing plate 2 upper surfaces with rise liquid pool 1 and contact, stalk pressing plate 2 lower surfaces contact with stalk seat board 4 upper surfaces with stalk 3 upper surfaces respectively and adopt screw to be fixed on the stalk seat board 4, during concrete enforcement, the described liquid pool inside that rises also is provided with and fills out fire-resistant mud layer 6.
Claims (1)
1. a low pressure casting rises liquid systems stalk joint structure, comprise and rise liquid pool, be arranged at the stalk pressing plate that rises liquid pool and rise liquid mouth below, parallel stalk and the stalk seat board that is arranged at stalk pressing plate below, it is characterized in that, the described liquid pool that rises rises liquid mouth place and has an extension that annular is downward, described extension end face directly contacts with the stalk upper surface, and described stalk pressing plate is set on the extension outer ring.
