Abstract

The utility model discloses a frame rack-mounted pneumatic microvibration multi-contact high-pressure forming pouring cup, which comprises a main body. The outer surface of the main body consists of a large upper end surface, a small lower end surface and an annular surface connected between the two end surfaces. The center of the main body is provided with a cone gate stick hole. Particularly, one side of the outer surface is a conical surface, while the other side thereof is an arc surface; and the two sides are connected at continuous curvature in a natural transition mode, wherein the upper end surface is provided with four threaded holes and the arc surface can be of an inverted paraboloid shape. The utility model aims to provide the frame rack-mounted pneumatic microvibration multi-contact high-pressure forming pouring cup, which is convenient for pouring operation, improves the production efficiency and improves yield of castings.

Description

The pneumatic microseism multiple contact of a kind of frame type rack high pressure moulding cup
Technical field
The utility model relates to a kind of equipment of Foundry Production, refers to the pneumatic microseism multiple contact of a kind of frame type rack high pressure moulding cup particularly.
Technical background
The pneumatic microseism multiple-contact high-pressure molding machine of frame type rack generally by jarring and system for compacting, multiple contact, quantitatively sand hopper and template more critical piece such as converting mechanism form.The pneumatic microseism multiple contact of its center type rack high pressure moulding cup (BMD mo(u)lding line cup) is to belong to a multiple-contact vitals.Multiple-contact effect is with the sand mold compacting, and the effect of the utility model cup is to be used for forming the sand mold cup, as the inlet of pouring molten iron.
Before the utility model proposes, the outer surface of producing the BMD mo(u)lding line cup of usefulness now is a conically shaped body.Because linear wall of cup steeper, the sand mold cup of moulding formation is when cast like this, and molten iron waters wall of cup along parabolic path, and the impulsive force of generation is bigger, forms turbulent flow easily, causes sand surfing.Turbulent flow has been involved in a large amount of air simultaneously, and the speed that makes molten iron enter gate stick reduces.Sand mold cup molten iron flows into die cavity and is obstructed, and causes " blocking up " phenomenon easily, at this moment the casting mold molten iron also poured short will overflow from the cup rim of a cup, cause the waste of molten iron.And, cause foundry goods to be prone to defectives such as misrun, cold shut like this because the operation of cutout back teeming takes place " blocking up " phenomenon easily.
Summary of the invention
The purpose of this utility model is that existing BMD mo(u)lding line cup is improved, and a kind of pouring practice that makes things convenient for is provided, and enhances productivity and improves the BMD mo(u)lding line cup of casting qualified rate.
The technical solution of the utility model realizes in the following manner, it has comprised body, the outer surface of body is made up of bigger upper surface, less lower surface and the ring surface that connects between the both ends of the surface, be provided with taper gate stick hole in body center, concrete, outer surface one side is a taper surface, and the another side is an arcwall face, and two continuous natural transition of side curvature are formed by connecting.
Four screwed holes are arranged on the upper surface of utility model mentioned above.
The cambered surface of utility model mentioned above is parabolic for falling.
Advantage of the present utility model is: because a side of the present utility model is an arc, the sand mold cast gate wall of cup that moulding forms is also more slow, and it is also less that molten iron waters the impulsive force that produces when hitting.Be not easy like this to form turbulent flow, reduced the possibility of sand washing.Simultaneously, the utility model has obviously improved the speed that molten iron enters gate stick, has shortened the duration of pouring, has strengthened the stamp ability, has improved operating efficiency.And the utility model helps controlling the molten iron flow velocity, realizes at the uniform velocity filling type, makes molten iron be difficult for overflowing, and has reduced the molten iron waste, has made things convenient for pouring practice.And, when cast, allow molten iron be full of cup about 2/3 and pour into a mould, can help the slag come-up, minimizing is involved in pore, has guaranteed the quality of foundry goods, has improved casting qualified rate.

The specific embodiment
Below in conjunction with the drawings and specific embodiments equipment of the present utility model is described in further detail:
Earlier according to the wooden model of drawing making the utility model.Begin to make body (5) at first, require arcwall face (4) and taper surface (2) to form the continuous natural transition of curvature.Taper gate stick hole (1) self-hardening sand core in the middle of making then stays 3mm allowance.Then this wooden model casting is become blank, material is HT200.Blank carries out polishing to arcwall face (4) after cooperating outer surface, gate stick bellmouth (1) and bore four M 12 screwed holes (3) through machining.
Shown in Fig. 2,4, the sand mold cup that has used the utility model moulding to form can obviously slow down the impulsive force that molten iron is poured into wall of cup, therefore is not easy to form turbulent flow, has reduced the possibility of sand washing.Simultaneously, obviously improve the speed that molten iron enters gate stick, shortened the duration of pouring, strengthened the stamp ability.And, made things convenient for pouring operation, help controlling the molten iron flow velocity, realize at the uniform velocity filling type, make molten iron be difficult for overflowing, reduced the molten iron waste.And, when cast, allow molten iron be full of cup about 2/3 and pour into a mould, can help the slag come-up, minimizing is involved in pore, has guaranteed the quality of foundry goods.
