Abstract
The invention relates to the field of die manufacturing, in particular to a vent design method for a casting die. The method comprises the following steps: (1) machining a pit b with the depth of 5mmin the position enclosed by an enclosure type or semi-enclosure type die cavity a, wherein the distance between the edge of the pit b and the edge of the die cavity a is 10mm; (2) machining a vent hole c in the position in which the vent hole can not interfere with other members of the die within the range of the pit b; and (3) in the die setting process, machining a vent trough d with the depth of 0.15mm in the position in which gas is retained in the die cavity, wherein both ends of the vent trough d are respectively communicated with the die cavity a and the pit b. By using the method of the invention, residual gas in the die cavity can be effectively eliminated, thereby ensuring that the integrity of the die product and shortening the development cycle of the die. The method is convenient and concise.
Description
Technical field
The present invention relates to mould manufacturing field, relate in particular to a kind of vent design method of casting mould.
Background technology
Along with the fast development of China's casting industry, casting mould has obtained extensive use, and the design of casting mould and manufacture level are also improving constantly.Traditional casting mould exhaust mode, employing pore and the air discharge duct exhaust when carrying out coremaking that begins to rehearse, but be limited to hydromechanical complexity, gas flow situation when when mould designs, being difficult to accurately prediction exhaust, add steam vent in the process of often wanting the pattern tool to use, and this steam vent of adding out easily and other member such as heating tube cause interference, even cause exhaust not smooth, residual gas in the mold cavity, the product defectiveness that causes Mould Machining to be come out, especially surround the die cavity of formula or semi-surrounding formula, difficult more when adding steam vent, defective is just more serious.
Summary of the invention
The objective of the invention is provides a kind of vent design method of casting mould at top described problem, can be good at solving the problem of exhaust problem.
The present invention is achieved by the following technical programs.
A kind of vent design method of casting mould may further comprise the steps successively.
(1) processes the dark pit of 2 ~ 5mm, the edge 7 ~ 10mm of the Edge Distance die cavity of pit at the position that encirclement formula or semi-surrounding formula die cavity are surrounded.
(2) position that does not interfere with other member of mould in the pit scope processes steam vent.
(3) during the die trial tool, gas delay place processes an air discharge duct that 0.1 ~ 0.15mm is dark in die cavity, and described air discharge duct two ends are communicated with die cavity and pit respectively.
The invention has the beneficial effects as follows: the present invention's employing processes a pit in the zone that die cavity is surrounded, and in pit, seek and process suitable steam vent, then when the die trial tool, the method of processing air discharge duct, can eliminate the die cavity residual gas effectively, thereby guaranteed that mould product is complete, convenient succinct, shortened mold developing cycle.
Description of drawings
Fig. 1 is the casting mould structural representation that the present invention relates to.
Fig. 2 is an A-A cutaway view among Fig. 1.
Among the figure, die cavity a, pit b, steam vent c, air discharge duct d.

(2) position that does not interfere with other member of mould in pit b scope processes steam vent c.
(3) during the die trial tool, gas delay place processes an air discharge duct d that 0.1mm is dark in die cavity a, and described air discharge duct d two ends are communicated with die cavity a and pit b respectively.
Embodiment two.
A kind of vent design method of casting mould may further comprise the steps successively.
(1) processes the dark pit b of 3mm, the edge 9mm of the Edge Distance die cavity a of pit b at the position that encirclement formula or semi-surrounding formula die cavity a are surrounded.
(2) position that does not interfere with other member of mould in pit b scope processes steam vent c.
(3) during the die trial tool, gas delay place processes an air discharge duct d that 0.13mm is dark in die cavity a, and described air discharge duct d two ends are communicated with die cavity a and pit b respectively.
Embodiment three.
A kind of vent design method of casting mould may further comprise the steps successively.
(1) processes the dark pit b of 5mm, the edge 10mm of the Edge Distance die cavity a of pit b at the position that encirclement formula or semi-surrounding formula die cavity a are surrounded.
(2) position that does not interfere with other member of mould in pit b scope processes steam vent c.
(3) during the die trial tool, gas delay place processes an air discharge duct d that 0.15mm is dark in die cavity a, and described air discharge duct d two ends are communicated with die cavity a and pit b respectively.
Claims (1)
