Abstract
The invention discloses a kind of sand shooting mouth for improving precoated sand mo ld void, is made up of upper die and lower die, the upper mould edge is provided with 4 splines, and center connects a guide post, and the guide post lower end is provided with a termination；Disk and targeting part with gradient of the lower mould by gyroscope type are constituted, and the Xia Mo centers are provided with cavity, and the guide post is located in the cavity, is provided with gap between the spline and lower modular belt gradient targeting part；Two ring annular grooves are provided with below disk, the sealing ring of silica gel material in cannelure, is studded with.During sand ejection board molding of the present invention, mould guide post head movement in drive can be taken back a part of hot sticky molding sand, increased sand mold shatter value, improve the breathability of sand mold；When compressed air stops, in sand shooting mouth, because Open Side Down, sand does not produce flowing to mould, and precoated sand stop motion, sand will not spill, and sand shooting mouth does not work.
Description
Technical field
The present invention relates to machinery manufacturing technology field, more particularly to a kind of sand shooting mouth for improving precoated sand mo ld void.
Background technology
It is related to iron mould casting technical field of mold, specifically refers to a kind of one kind of swage precoated sand moulding mould manufacture and penetrate
Sand mouth.Common sand shooting mouth, when not working, sand shooting mouth can produce Lou sand phenomenon, cause to waste sand, while die surface is difficult clearly
Reason.
The content of the invention
To solve above-mentioned technical problem present in prior art and reality, present invention offer is a kind of to improve precoated sand sand mold
The sand shooting mouth of breathability, is made up of upper die and lower die, and the upper mould edge is provided with 4 splines, and center connects a guide post,
The guide post lower end is provided with a termination；Disk and targeting part with gradient of the lower mould by gyroscope type are constituted, the lower mould
Center is provided with cavity, and the guide post is located in the cavity, is provided between the spline and lower modular belt gradient targeting part
Gap.
Preferably, two ring annular grooves are provided with below disk, in cannelure, stud with the sealing ring of silica gel material.
Preferably, the sand shooting mouth uses 45#Structural steel makes.
Preferably, the tip diameter is 12 mm.
The present invention has following technique effect：
1st, in sand shooting mouth, mould is oriented to club head and carries a termination, and sand ejection board can be taken back a part of sand when returning, become sand mold
Obtain loosely, increased the breathability of sand mold.
2nd, lower mould adds the targeting part with gradient to constitute by the disk of gyroscope type.Two ring annular grooves are provided with disk, annular
Sealing strip is studded with groove, prevents sand from revealing, sealing is good.
3rd, sand shooting mouth is installed according to the quantity of sand mold, sand ejection board is moved under cylinder action in slideway, by penetrating
Sand shooting mouth on sand plate accurately totally completes sand casting.
4th, sand shooting mouth sealing is good, has prevented sand waste, while improve the workload of cleaning quicksand, improves life
Produce efficiency.
Description of the drawings
Fig. 1 is the front view of the sand shooting mouth of the raising precoated sand mo ld void of the embodiment of the present invention.
Fig. 2 is that the sand of the sand shooting mouth of the raising precoated sand mo ld void of the embodiment of the present invention flows to schematic diagram.
Specific embodiment
Technical solution of the present invention is discussed in detail below in conjunction with the accompanying drawings.
As shown in Figure 1 and Figure 2, the sand shooting mouth for improving precoated sand mo ld void uses 45#Structural steel makes, by 1 He of upper mould
Lower mould 2 is constituted, and 1 edge of upper mould is provided with 4 splines 3, and center connects a guide post 4, and 4 head of guide post has a cap.Under
Mould is made up of the disk 5 of gyroscope type and the targeting part 6 with gradient.Two ring annular grooves 7 are provided with disk, are studded with cannelure 7
The sealing ring of silica gel material, the effect of sealing ring are to prevent sand from spilling from sand shooting mouth frock edge, affect the surface matter of sand mold
Amount.
The operation principle of the present invention is that in sand shooting mouth, the raised pawl of four splines of mould is welded in sand ejection board, lower mould
It is scheduled in sand ejection board by interference fit state, sand ejection board thickness 20mm.A lower bands funnel is placed with during work on 4 meters of high workload platforms
Square sandbox（Sandbox specification 1000mm × 1000mm）, the mobility of sand causes sand to pass through funnel stream under gravity
Cylinder on the high support stands of 3m（Lower bands funnel）One-level sand bucket, sand flow into trapezoidal sandbox by two grades of sand buckets again,
Trapezoidal sandbox bottom studs with sand ejection board, and sand shooting mouth upper die and lower die are each attached in the thick sand ejection boards of 20mm, are designed according to sand shooting mouth
Principle, after sand shooting mouth is installed, upper mould spline leaves 5mm gaps, the sand in trapezoidal sandbox with lower modular belt gradient targeting part
Under the additional compression air effect being passed through, sand is made to produce motion, sand is by 4 splines of upper mould with lower die guiding to part
Middle 5mm gaps, penetrate sand along guide post quickly through sand shooting mouth, full of sandbox die cavity, complete modeling process.Sand ejection board molding
When, mould guide post head movement in drive can be taken back a part of hot sticky molding sand, increased sand mold shatter value, improve sand mold
Breathability；When compressed air stops, in sand shooting mouth, because Open Side Down, sand does not produce flowing, precoated sand stop motion, sand to mould
Son will not spill, and sand shooting mouth does not work.The present invention improves the onsite application that the sand shooting mouth of precoated sand mo ld void passes through 2 years
Effect is fine.
Finally it should be noted that：The preferred embodiments of the present invention are the foregoing is only, the present invention is not limited to,
Although being described in detail to the present invention with reference to the foregoing embodiments, for a person skilled in the art, which still may be used
To modify to the technical scheme described in foregoing embodiments, or equivalent is carried out to which part technical characteristic.
All any modification, equivalent substitution and improvements within the spirit and principles in the present invention, made etc., should be included in the present invention's
Within protection domain.
