Detailed description of the invention
Refer to Fig. 1 to Fig. 4, the cast gate automatic cut-off device of the present embodiment, it is used for excising runner cast gate, including being located at
State the excision mechanism at runner gate location, for driving described excision mechanism action when die sinking so that described excision mechanism cuts
Drive mechanism except described runner cast gate.Described excision mechanism includes a slide block 20, is located on described slide block 20 corresponding to described
Excising parts and being used for the line position guide holder 22 that described slide block 20 is guided at runner gate location.When die sinking, described
Drive mechanism drives described slide block 20 to move to the direction away from runner cast gate while moving with die sinking direction, so that institute
State excision parts cut away runner cast gate；When the die is closed, described drive mechanism drives described slide block with matched moulds direction while moving
20 reset, so that described excision parts are positioned at described runner cast gate at matched moulds recurrence of disease at the same time next year.The cast gate of the present embodiment excises automatically
Device also includes one for the stroke positioning mechanism positioning the stroke of slide block 20.Specifically:
Described line position guide holder 22 has a U-shaped guide chute 221, and one end of described U-shaped guide chute 221 is positioned at institute
State first side (in this example, this first side is right side) of runner cast gate, under the guide effect of U-shaped guide chute 221, described cunning
Block 20 can move back and forth along the axial direction being perpendicular to runner cast gate.Described slide block 20 near one end of described runner cast gate to
The direction of described runner cast gate extends one thin piece 201, and described excision parts water corresponding to runner for being located on described thin piece 201
The perforation 202 of the position of mouth, the hole wall of described perforation 202 is can excise described runner cast gate sharp, this perforation 202
With described runner cast gate concentric, the aperture of this perforation 202 is slightly larger than the bore of runner cast gate.In this programme, when die sinking, institute
State drive mechanism drive described slide block 20 towards away from the direction (the present embodiment be towards move left) of described runner cast gate mobile time, institute
State perforation 202 to move with described slide block 20, so that described sharp is cut off described runner cast gate；When the die is closed, described cunning
Block 20 resets so that described perforation 202 is reset to home position.In this programme, slide block 20 extends described thin piece 201,
Make incisory perforation 202 be located on this thin piece 201, its benefit be can reduce perforation 202 offer difficulty, save former material
Material.In other examples, described cutting part can also is that other structure, such as, be similar to arc cutting tulwar, sickle
Knife-like etc., as long as making their sharp face be positioned at the second side relative with described first side at runner cast gate, so that
Proper slide block 20 under the drive of driver part away from cast gate time, drive described excision parts sharp towards described first side
Direction moves to excise described runner cast gate.
In the present embodiment, described drive mechanism is a shovel base 30 being inserted on described slide block 20, the length of described shovel base 30
Degree direction is perpendicular with the glide direction of described slide block 20.Described slide block 20 offers a confession described shovel base 30 be inserted in
Slot therein, described slot is the moving direction to described slide block 20 and downward-sloping tipper 203, described tipper
The angle of inclination of 203 is 25～30 degree.Described shovel base 30 have the fixed block 301 on a front mould being fixed on mould and
It is located at the drive part 303 matched with described tipper 203 bottom described fixed block 301, the inclination angle of described shovel base 30
Degree is 25～30 degree that the angle of inclination with described tipper 203 matches.
When die sinking, described shovel base 30 moves straight up, owing to the drive part 303 of shovel base 30 is downwards and to Right deviation
Tiltedly, therefore when shoveling base 30 and moving straight up along die sinking direction, stir described slide block 20 and move right, so that described perforation
202 are moved to the left and cut off described runner cast gate；When matched moulds, described shovel base 30 returns to incline with the direction of matched moulds straight down
In skewed slot 203, stir described slide block 20 in this process and be moved to the left reset, so that described excision member reset.
Described stroke positioning mechanism is for positioning the shift motion of slide block 20, and anti-limited slip block 20 continues because of inertia
To the right or be moved to the left, it is ensured that the drive part 303 shoveling base 30 when matched moulds can be accurately aimed at tipper 203, thus ensures
The good of whole automatic cut-off device runs and auto-reset function.Specifically, described stroke positioning mechanism includes being located at described U
The stroke locating clip 40 with vertical elastic force on the diapire of shape guide chute 221, in the bottom of described slide block 20 along described cunning
Block 20 moving direction is arranged at intervals with the locating slot 41 of two and described stroke locating clip 40 location fit；Said two locating slot
The stroke that the distance of 41 departs from described tipper 203 with described shovel base 30 matches, and under matched moulds state, described stroke positions
Away from locating slot 41 location fit of described runner cast gate in the top of folder 40 and two locating slots 41, in die opening state
Under, the top of described stroke locating slot 41 and said two locating slot 41 are joined near locating slot 41 location of runner cast gate
Close.
Described stroke locating clip 40 includes the vertical self-recoverage spring being fixed on the diapire of described U-shaped guide chute 221
401 and be located at the locating clip body 402 on described self-recoverage spring 401 top, described locating clip body 402 has one upwards
Tip；Described locating slot 41 is the cone tank matched with this tip.
As the preferred scheme of one, described stroke locating clip 40 also includes enclosing outside described self-recoverage spring 401
Guide chamber 403, one end towards the diapire of described U-shaped guide chute 221 of described guide chamber 403 is fixedly arranged on described diapire.
This utility model embodiment, during mould die sinking, slide block 20 will make runner water by the guiding movement of shovel base 30 automatically
Mouth cuts off, and slide block 20 is positioned at shovel base 30 just off the position (drive of shovel base 30 during slide block 20 by stroke positioning mechanism
When the lower end of part 303 is placed exactly in the upper end of tipper 203, the position at slide block 20 place), to ensure to shovel base 30 when matched moulds
Can be returned in tipper 203, when matched moulds, shovel base 30 band movable slider 20 resets, and excises for cast gate next time and performs standard
Standby.Cast gate automatic cut-off device of the present utility model is stable, without artificial secondary operations again at Jiao Kou, it is achieved that the most certainly
Dynamic production, improves production efficiency and reduces production cost.
These are only embodiment of the present utility model, not thereby limit the scope of the claims of the present utility model, every profit
The equivalent structure made by this utility model description and accompanying drawing content or equivalence flow process conversion, or directly or indirectly it is used in it
The technical field that he is correlated with, is the most in like manner included in scope of patent protection of the present utility model.
