Abstract
The utility model provides a full sand core casting mold for preventing the defect that sand holes can be formed in a casting cast by the conventional full sand core casting mold. The full sand core casting mold is easy to realize in operation and is characterized in that an entire exhaust passage is designed to be curvilinear, that is, a segment at one end close to a core cavity and a segment at one end close to an exterior cavity are staggered, so that not only the venting effect in the core cavity during the casting is guaranteed, but also fallen exterior sands can be prevented from falling into the core cavity through the exhaust passage and are cast together with a casting so as to cause sand holes in the casting.
Description
Technical field
The utility model belongs to casting field, relates to a kind of foundry goods that prevents that full core casting mold casting from forming and produces the full core casting mold of a kind of exhaust passage of staggering of sand holes defective.
Background technology
For guaranteeing the exhaust effect of full core casting mold when casting, all can be designed to straight line to the exhaust passage generally speaking, be that the exhaust passage is over against outer die cavity, the method for designing of this exhaust passage is easy to cause outer molding sand directly to fall in the core chamber along the exhaust passage, promptly produce foundry goods sand holes defective after the casting, the lighter's foundry goods is done soldering and is handled, and weight person causes foundry goods directly to scrap.
Summary of the invention
The purpose of this utility model is to provide a kind of foundry goods sand holes defect problem under the straight line exhaust air technique that solves full core casting mold that is, and don't influence the exhaust effect of casting mold, former straight line method for exhausting is improved, change the curve exhaust mode into by the straight line exhaust mode.
The technical solution of the utility model is as follows: comprise core chamber, exhaust passage, feature is: between the exhaust passage of core chamber end and the external form end exhaust passage auxiliary exhaust passageways is arranged.
Near the exhaust passage of core chamber end and near being crooked exhaust passage between the exhaust passage of external form end, there have auxiliary exhaust passageways to connect to be logical.
Advantage of the present utility model is as follows:
1, both solves foundry goods sand holes problem, do not influenced exhaust effect again.
2, the design of curve exhaust passage and easy to manufacture can not increase the cost input.
Description of drawings
Full core casting mold sectional plan view when Fig. 1 is the bending of the utility model exhaust passage.
In the accompanying drawing, core chamber (1), exhaust passage (2), auxiliary exhaust passageways (3), exhaust passage (4).
The specific embodiment
Most preferred embodiment of the present utility model is such, and with reference to accompanying drawing, because the exhaust passage of casting sand core all is straight line before, easy like this have an outer molding sand that drops, and easily causes foundry goods to produce the defective of sand holes.For this reason, we have designed and a kind ofly the exhaust passage have been made crooked, promptly have auxiliary exhaust passageways (3) to be connected near between one section exhaust passage (2) of interior core chamber (1) end and the close exhaust passage (4) of outer die cavity end, form forniciform exhaust passage.With the gas exhaust channels designs in core chamber (1) is three sections, every adjacent two sections exhaust passages are UNICOMs, and auxiliary exhaust passageways (3) UNICOM that links by another and the exhaust passage (4) of close external form end near one section exhaust passage (2) of core chamber (1) end together.One section close core chamber, the exhaust passage on core end still is designed to direct UNICOM core chamber, one section remaining exhaust passage is by another that section exhaust passage auxiliary exhaust passageways UNICOM at angle with close core chamber end, and stagger fully near that section exhaust passage of core chamber end, the gas that produces in the core chamber when so casting will discharge along curved channel, and the molding sand that external form drops can not fall into yet and form the sand holes defective in the core chamber.
Claims (2)
1. the full core casting mold of the exhaust passage of staggering comprises core chamber, exhaust passage, it is characterized in that, between exhaust passage (2) of core chamber (1) end and the external form end exhaust passage (4) auxiliary exhaust passageways (3) is arranged.
2. according to the full core casting mold of the described a kind of exhaust passage of staggering of claim 1, it is characterized in that there have auxiliary exhaust passageways (3) to connect to be logical near the exhaust passage (2) of core chamber (1) end and near being crooked exhaust passage between the exhaust passage (4) of external form end.
