Specific implementation mode
Referring to Fig. 1-Fig. 7, the present invention provides a kind of vacuum foams to seal material device, including the upper cover 2 fastened up and down is under
Lid 4 offers material hole 21 in the upper cover 2, offers lower material hole 41 on the lower cover 4, the upper material hole 21 with
41 consistency from top to bottom of lower material hole, the upper cover 2 fastened up and down and forms control flume between lower cover 4, in the control flume
Equipped with sliding block 3, the sliding block 3 can be slided along the control flume, the upper plane of the sliding block 3 and the lower plane 25 of the upper cover
Cooperation, the lower plane of the sliding block 3 and the upper plane of the lower cover 4 coordinate, the glide direction of the sliding block 3 and the upper material feeding
The axis perpendicular in hole 21 offers connecting hole 31 on the sliding block 3, and the connecting hole 31 is connected to the upper plane of the sliding block 3
By the selective connection of the connecting hole 31 or the upper note is closed with the sliding block 3 of the lower plane of the sliding block 3, sliding
Expect hole 21 and the lower material hole 41.
Expect that device is assembled on the sprue of foaming mould in practical application, needing first to seal vacuum foam, when needs pair
Inside foaming mould when injection expanding foam solution, material feeding rifle is inserted into upper material hole 21, mobile sliding block 3 makes the company on sliding block 3
The lower section that hole 31 is moved to material hole 21 is connect, the upper end of connecting hole 31 is connect with the lower end of upper material hole 21 at this time, and is connected
The lower end in hole 31 is connect with the upper end of lower material hole 41, to realize the connection between upper material hole 21 and lower material hole 41,
And lower material hole 41 is connected to sprue, thus material feeding rifle is directly connected to foaming mould inside at this time, material feeding rifle foam-injection
Liquid, thus expanding foam solution will be directly injected into foaming mould, after expanding foam solution injects, need to send out in material feeding rifle and vacuum
When bubble envelope material device separation, then pass through mobile sliding block 3 so that the connecting hole 31 on sliding block 3 and upper material hole 21 and lower material hole
Dislocation (upper material hole 21 is not connected to connecting hole 31, while connecting hole 31 is not connected to lower material hole 41) is generated between 41, from
And realize the purpose of closing sprue, and then material feeding rifle is sealed from foaming on material device remove again.
Relative to existing by the way of manually blocking sprue, embodiment of above is more convenient, can also prevent
Sprue closes the appearance of incomplete situation.
It is slided in control flume in order to facilitate sliding block 3, the present invention also sets up cylinder 5, and cylinder 5 connect with the sliding block 3, passes through
Cylinder 5 is moved with movable slider 3, and realization automatically controls closing sprue, and (connecting hole 31 and upper material hole 21 and lower material hole 41 are not
Connection) and connection sprue (connecting hole 31 is connected to upper material hole 21 and lower material hole 41).
The upside of the sliding block 3 is further opened with sliding block inclined-plane 32, the upper plane of the sliding block inclined-plane 32 and the sliding block 3 it
Between angle=sliding block 3 glide direction and the sliding block inclined-plane 32 between angle, the lower plane 25 of the upper cover to
Under be extended with 32 matched upper cover inclined-plane 26 of the sliding block inclined-plane, on the sliding block inclined-plane 32 and 26 phase of upper cover inclined-plane
When fitting, the connecting hole 31 is detached with projection of the upper material hole 21 on 3 lower plane of the sliding block.
The setting on sliding block inclined-plane 32 and upper cover inclined-plane 26, when closing sprue, cylinder 5 pushes sliding block 3 to move so that sliding
Block 3 is moved to side, and connecting hole 31 will be detached with upper material hole 21 and lower material hole 41, and sliding block 3 continues to move to, sliding block inclined-plane
The distance between 32 and upper cover inclined-plane 26 become smaller, until sliding block inclined-plane 32 is contacted with upper cover inclined-plane 26, and cylinder 5 is still to sliding block
3 exert forces are applied to by sliding block inclined-plane 32 on upper cover inclined-plane 26, and since sliding block 3 can not continue to move to, thus sliding block 3 is just
Can by from the reaction force on upper cover inclined-plane 26, the reaction force perpendicular to upper cover inclined-plane 26 and downwards, thus sliding block 3 by
One downward strength, therefore it is bonded more tight between the lower plane of sliding block 3 and the upper plane of lower cover 4, thus cunning can be enhanced
Block 3 closes the effect of sprue.
The quantity on the sliding block inclined-plane 32 is 2, and 2 sliding block inclined-planes 32 are in the same plane, and 2 cunnings
Block inclined-plane 32 is located at the both sides of the connecting hole 31.
The fixing groove 22 for fixed electromagnet 23 is offered in the upper plane of the upper cover 2, is set in the fixing groove 22
It is equipped with electromagnet 23.
In order to reinforce the leakproofness being connect between material feeding rifle and upper material hole 21, by the way that electromagnet 23 is arranged, note certainly
Also corresponding fixed iron piece on spray gun, when material feeding rifle and upper material hole 21 coordinate, electromagnet 23, which is powered, to be generated magnetic field and adsorbs iron
Piece, to ensure the leakproofness between material feeding rifle and vacuum foam envelope material device.
The setting of inductive switch 24, can automatically detect whether material feeding rifle coordinates with upper material hole 21, realize automatic control
Electromagnet 23 processed, which is powered, generates magnetic field, and realization automatically controls.
Certainly, it is contemplated that whole aesthetics can set layer protective layer 1 in the upper plane upper cover 2 of upper cover 2.
The oil seal groove 42 of annular, the axis of the oil seal groove 42 and the bet are offered in the upper plane of the lower cover 4
The axis in hole 41 is expected on same straight line, and the oil seal groove 42 is located at the outside of the lower material hole 41.
Under normal circumstances, oil seal groove 42 is connected to oil can, and first, in the process that sliding block 3 slides, increase sliding block 3
Lubricity between lower plane and the upper plane of lower cover 4；The second, enhance the sealing on 3 lower plane of sliding block and lower cover 4 between plane
