Description
Technical field
Core shooter frock field is the utility model is related to, particularly relates to a kind of sand seat mould of ZM bearing block bases.
Background technology
At present, China's casting industry generally manufactures sand core using hot box.Its manufacturing process approximately as：Will casting
The sand material being mixed into sand, thermosetting resin and catalyst is injected into the core box with heating unit by core shooter, heating
To 250 to 320 degrees Celsius, the sand material close to box surface is set to be heated, the binding agent in sand material can contract in a short period of time
Poly- hardening, and then form core.Foundry sand is generally injected in the cavity of hot core box mould by sand shooting mouth.
In existing machinery industry, bearing block it is widely used, in the design and production process of bearing block core mould
In, since the volume of some bearing blocks is larger, for such core box in design, the depth of cavity is also bigger, so needing corresponding
Increase the height of cast gate, and the position of running channel and penetrate that the influence that the structure of sand mouth casts the later stage is very big, and unreasonable sets
Put and easily lead to casting rejection rate increase；In the application of bearing block, the fuse being used cooperatively with bearing block is had, due to core
Minor structure is more complicated, and easily snaps off or crush after fuse coremaking.
Utility model content
The utility model is existing to solve the problems, such as, proposes a kind of sand seat mould of ZM bearing block bases.
What the technical solution of the utility model was realized in：
A kind of sand seat mould of ZM bearing block bases, core mould includes sand seat upper mold and sand seat lower die, in sand seat lower die
Downside set and there are five to penetrate Sha Kou, be both provided with air discharge duct in other three sides of sand seat lower die, shape after sand seat mold clamping
Into the cavity identical with the base shape of bearing block, the running channel of double cast gate is set in the middle part of the cavity of sand seat upper mold, and running channel is threeway
Road running channel, is provided with some location holes, in the cavity bottom of sand seat upper mold and sand seat lower die in sand seat upper mold and sand seat lower die
Equipped with centre hole, the air discharge duct of sand seat lower die is communicated with cavity, is penetrated Sha Kou front ends and is connected with sand shooting mouth, penetrates Sha Kou rear ends and cavity
Connection, penetrate sand mouth point diameter to penetrate Sha Kou rear ends it is a diameter of gradually increase, below the cavity of sand seat upper mold and sand seat lower die
One group of bottoming hole is respectively provided with, electrically heated rod is inserted at bottoming hole, is additionally provided with and penetrates in sand seat upper mold and the rear portion of sand lid lower die
Sand machine coordinates the frock hole of installation.
The beneficial effects of the utility model are：
1. the utility model can realize efficient casting, the diameter for penetrating sand mouth gradually increases, and improves the speed for penetrating sand, carries
High qualified casting, the adjustment of running channel position can accelerate the speed poured, increase yield rate；
Reduced 2. the bearing block that the utility model can make to cast out is machined, save material and artificial cost, Yi Shi
Existing automated production.
