Bucket, sand flashboard and sand flashboard fixing seat, the lower end outlet of the sand hopper are connected with the upper end entrance for penetrating bucket by sand flashboard fixing seat
Logical, the bottom end side of the extending inwardly to form annular protrusion of the sand flashboard fixing seat, the upper surface of side's annular protrusion is equipped with close
Seal fixing groove, is fixed with sealing ring in the sealing ring fixing groove, the one side wall of the sand flashboard fixing seat be equipped with it is interior
The opening of chamber connection, the sand flashboard is by being pullably slidably connected to Fang Huan after being open into the inner cavity of sand flashboard fixing seat
The upper surface of shape protrusion, the top of the sand flashboard fixing seat are equipped with several apertures being connected to inner cavity, each aperture
Top is equipped with piston rod compression cylinder directed downwardly.
Further, the sand flashboard fixing seat includes fixing seat upper cover and fixing seat lower cover, the fixing seat upper cover and
Fixation is bolted between fixing seat lower cover.
Further, the upper surface of the fixing seat lower cover and square annular protrusion form first step, in the fixing seat
The lower end surface of lid is equipped with the second step opposite with first step, is formed with sand supplying between the first step and second step
The sliding guide groove of gate panel slide.
Further, the quantity of the compression cylinder is four.
Further, the sand flashboard is electric brake plate valve.
The utility model has the advantages that the utility model is provided with compression cylinder above sand flashboard, compression cylinder can be incited somebody to action when penetrating sand
The sand flashboard of closed jetting bucket compresses downwards, and sand flashboard is allowed to be close to sealing ring always in core-shooting process, to improve
The leakproofness that bucket penetrates sand is penetrated, prevents core sand from leaking out by penetrating the upper end entrance of bucket, avoids the waste of core sand and ensure that and penetrate
The quality of sand, while also avoiding the core sand being scattered and the application maintenance of equipment is impacted.
Detailed description of the invention
The utility model is described further with reference to the accompanying drawings and examples:
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the top view of the utility model；
Fig. 3 is the structural schematic diagram of sand flashboard fixing seat in the utility model embodiment.
Specific embodiment
Referring to Figures 1 and 2, the utility model is a kind of 3 pressure seal of sand flashboard, including sand hopper 1, penetrates bucket 2, Sha Zha
The lower end outlet of plate 3 and sand flashboard fixing seat 4, the sand hopper 1 is connected to the upper end entrance for penetrating bucket 2 by sand flashboard fixing seat 4,
The bottom end side of the extending inwardly to form annular protrusion 43 of the sand flashboard fixing seat 4, the upper surface of side's annular protrusion 43 are equipped with
Sealing ring fixing groove is fixed with sealing ring 5 in the sealing ring fixing groove, and the one side wall of the sand flashboard fixing seat 4 is equipped with
The opening being connected to inner cavity, the sand flashboard 3 after being open into the inner cavity of sand flashboard fixing seat 4 by being pullably slidably connected
In the upper surface of square annular protrusion 43, the top of the sand flashboard fixing seat 4 is equipped with several apertures being connected to inner cavity, each institute
It states and is equipped with the compression cylinder 6 directed downwardly of piston rod 61 above aperture, specifically, the quantity of the compression cylinder 6 is four, respectively
The compression cylinder 6 is located at the four corners at 4 top of sand flashboard fixing seat, so that each piston rod 61 is pressed downward tight sand lock
Uniform pressure can be applied to sand flashboard 3 when plate 3, guarantee the leakproofness between the sand flashboard 3 and sealing ring 5.
