Abstract
A kind of mold air exhaust rod, exhaust bar body be step cylindrical-shaped structure, including be placed in outside mold big stage portion, be plugged in vent bore with gas vent clearance fit to form the small stair portion of exhaust passage；The exhaust bar body is additionally provided with auxiliary exhaust passageways, and the auxiliary exhaust passageways are formed by venthole, for being connected to the lead-over groove of venthole and vent bore, and auxiliary exhaust passageways keep exhaust rapider.The utility model belongs to mold design field, is mainly used for solving the problems, such as that existing air exhaust rod exhaust is unsmooth and is frequently occluded.The utility model has the characteristics that simple in structure, dependable performance, of low cost, reduces because of loss due to spoiled work caused by die venting is unsmooth.
Description
Technical field
The utility model is related to cast to use equipment Design field, make metal casting mould especially suitable for heat.
Background technology
In foundry production, liquid alloy injection cavity postcooling, solidification are obtained into final products.To obtain
Whole casting must make liquid alloy be full of entire mold cavity, this just there are certain requirements upper parting line venting.At the top of mold cavity
Pneumatosis certainly exists, so needing that gas vent and air exhaust rod is arranged in upper mold.As shown in Figure 1, exhaust bar body is step
Shape cylindrical-shaped structure, including be placed in outside mold big stage portion 2 ', the small stair portion 3 ' for being plugged in gas vent, big step
Portion 2 ' is equipped with lifting hole 1 '.The gap formed with gas vent using small stair portion is exhausted, but since this exhaust clearance is long and narrow,
It is easy to be blocked, to lose scavenging action.
Invention content
The goal of the invention of the utility model provides a kind of structure letter to overcome existing air exhaust rod above shortcomings
List, dependable performance, convenient for disassembly and assembly, low-cost mold air exhaust rod.
The technical solution of the utility model is：Exhaust bar body is step cylindrical-shaped structure, including is placed in outside mold
Big stage portion, be plugged in vent bore with gas vent clearance fit to form the small stair portion of exhaust passage；The row
Gas bar body is additionally provided with auxiliary exhaust passageways, the auxiliary exhaust passageways by venthole, for being connected to venthole and die venting
The lead-over groove in hole forms.
There is distance in the lead-over groove end with small stair portion end.
The lead-over groove is two, and two lead-over grooves intersect vertically.
The auxiliary exhaust passageways pass through the axis of exhaust bar body.
The sum of the length of the venthole and the length of lead-over groove are less than the length of exhaust bar body.
The big stage portion is equipped with lifting hole.
The lifting hole and venthole vertically through.
The venthole is located in the middle part of exhaust bar body.
In use, small stair portion is inserted into vent bore, make big step lower plane and plane contact in upper mold, at this time
It is installed in place.Gas is arranged by the gap that gas vent and small stair are formed using lead-over groove and venthole during casting pouring
Go out, you can play scavenging action.
Compared with existing air exhaust rod, the utility model increases lead-over groove vent design, due to gas energy in exhaust process
It is enough that lead-over groove is promptly entered by cavity and is discharged by venthole, so that exhaust velocity is increased, exhaust passage is more unobstructed, avoids
Waste product is poured into a mould caused by exhaust passage is blocked.
Description of the drawings
Fig. 1 is the working state schematic representation of existing air exhaust rod.
Fig. 2 is the structural schematic diagram of the utility model.
Fig. 3 is the sectional view of Fig. 2.
Specific implementation mode
In Fig. 2, Fig. 3, air exhaust rod be step cylindrical-shaped structure, including be placed in outside mold big stage portion 2, be plugged in mould
Have in gas vent with gas vent clearance fit to form the small stair portion 3 of exhaust passage, be set to small stair portion and pass through its axis
Two holes 4 of line pass through two lead-over grooves 5 of 4 axis of hole and small stair portion axis, are set to the venthole 6 of exhaust rod axis.Two
A hole 4 is mutually perpendicular to for axis.Lead-over groove 5 is extended from hole 4 to small stair lower plane, but has certain distance apart from lower plane, with
Prevent air exhaust rod from blooming deformation.Venthole 6 at the top of big step by extending to hole 4.Big stage portion is equipped with lifting hole 1.Big step
2 bottom lower plane of portion and plane contact in upper mold 7, prevent air exhaust rod from falling into mold cavity.Lead-over groove 5 is narrow slot, by hole 4
Wire cutting is carried out downwards to be formed.
In use, small stair portion 3 is inserted into the gas vent of upper mold 7, make 2 lower plane of big stage portion and plane in upper mold 7
Contact, gas during casting pouring in mold cavity 8 will by the gap that the gas vent on mold is formed with small stair portion 3
Gas is discharged.The channel that lead-over groove 5 and venthole 6 are formed increases exhaust clearance, keeps exhaust more smooth.In the daily dimension of mold
In shield maintenance, lead-over groove 5 and small stair portion 3, venthole 6 will carry out periodic cleaning maintenance, only need to pass through lifting with extracting tool
Air exhaust rod is pulled out and is cleared up by hole 1.
