Abstract
A novel sealed exothermic riser support pillar comprises a riser inner support pillar, a spring rod, a spring, a seal ring and a stop screw, wherein the riser inner support pillar is formed by a support pillar body and a seal ring press cover, the inner upper end of the support pillar body is provided with a center circular hole and a seal ring seam allowance, the lower end of the support pillar body is provided with a center screw hole so as to be connected with a mould body, and the side wall of the support pillar body is provided with a stop screw hole; and the spring rod is a round bar, the top end of the spring rod is a semi-spherical body and supports the top of an inner cavity of the riser, the middle of the spring rod is provided with a position limited slot, the lower part of the spring rod is a reducing round bar and is provided with the spring, and the stop screw is screwed into the position limited slot of the round bar through the stop screw hole so as to be in sliding fit with the spring rod to control the stroke of the spring rod. The novel sealed exothermic riser support pillar has the advantages that the exothermic riser support pillar has a simple structure, and is convenient to manufacture and install, the seal ring of the inner support pillar of the riser is tightly contacted with the spring rod, thus playing a good seal role, and preventing moulding sands from entering into the cavity and the spring rod so as not to be blocked in the cavity of the inner support pillar of the riser, reducing maintenance and replacement times of the exothermic riser support pillar, and lowering cost and the cast reject ratio.
Description
(1) technical field
The utility model relates to the casting and molding technology, particularly a kind of novel seal exothermic riser fore-set.
(2) background technology
At present casting industry is more and more extensive for the utilization that increases the exothermic riser technology in modeling process, and the exothermic riser fore-set is a key component of the exothermic riser that uses in the modeling process.The exothermic riser fore-set that generally uses now is the monoblock type fore-set without sealing device, this exothermic riser fore-set leaks moulding sand easily in the use procedure of moulding, it is also stuck to cause exothermic riser fore-set internal friction power to increase rapidly, reduce the service life of fore-set, also increased the fraction defective of casting simultaneously.
(3) utility model content
The purpose of this utility model is for above-mentioned existing problems, and a kind of simple in structure, easy to make and novel seal exothermic riser fore-set that sand leakage avoiding is respond well is provided.
The technical solution of the utility model:
A kind of novel seal exothermic riser fore-set, comprise fore-set, spring lever, spring, sealing ring and stop screw in the rising head, fore-set is made of fore-set body and sealing ring gland in the rising head, the fore-set body is Elliptic Cylinder, the upper end is provided with center hole and sealing ring seam in the fore-set body, and the lower end is provided with center screw and is connected with die ontology, and sidewall is provided with the stop screw hole, sealing ring places in the sealing ring seam, and the fore-set body is connected two bolt seal and connects with the sealing ring gland; Spring lever is round bar, the round bar top is the hemisphere face body and is supported in the rising head inner cavity top, the round bar middle part is provided with stopper slot, the bottom is the undergauge round bar, spring is arranged at undergauge round bar part, center hole in spring lever and the fore-set body forms and is slidingly matched, and spring lever and sealing ring form slipper seal, and stop screw is slidingly matched with the stroke of control spring bar by stopper slot and the spring lever formation that the stop screw hole screws in round bar.
The utility model advantage: this exothermic riser fore-set is simple in structure, fabrication and installation convenient; Sealing ring and the spring lever close contact of fore-set in the rising head, can play good sealing function, guaranteed the fit clearance of base intracavity, prevent that moulding sand from entering inner chamber, prevent that spring lever is stuck in the fore-set inner chamber in rising head, the maintenance that reduces the exothermic riser fore-set with change number of times, reduced cost, decrease the casting fraction defective.
