Abstract
The utility model discloses a circular hole vent plug, and relates to the technical field of vent plugs. The round hole vent plug comprises a hole surface and a ring surface, wherein the hole surface is arranged at the bottom of the ring surface, the hole surface is made of one of polyformaldehyde and glass fiber, and the ring surface is made of one of polyformaldehyde and glass fiber. The round hole vent plug is made of a novel material design, so that the round hole vent plug is not easy to deform in the production and use processes due to the characteristics of high hardness, high rigidity, high wear resistance and the like; meanwhile, due to the round hole design, sand and resin are not easy to block in the production process, exhaust is smooth and clean, the quality of the sand core is more stable, the replacement frequency of the exhaust plug is greatly reduced, and the production efficiency is improved.
Description
Technical Field
The utility model relates to the technical field of vent plugs, in particular to a circular hole vent plug.
Background
In the field of casting, cold box is a common method for manufacturing sand cores. In order to fully shoot sand and blow ammonia to purify the bottom/raised side surface of the inner cavity of the core box and other parts far away from a sand shooting port. When a product is designed for developing a core box, an exhaust plug is usually arranged on the side surface of the bottom/bulge of an inner cavity of the core box or a part far away from a sand shooting port. The shape of the core box vent plug can directly relate to the difficulty degree of the core box in the production and cleaning processes, and the production efficiency is influenced. Reasonable cost can also lead the enterprises to obtain more profits and profits.
SUMMERY OF THE UTILITY MODEL
Technical problem to be solved
Aiming at the defects of the prior art, the utility model provides the round hole vent plug, which solves the problems that the traditional copper vent plug is very easy to deform in the using and cleaning processes due to the good plasticity of copper, and the core of the vent plug needs to be replaced once the vent plug deforms; meanwhile, the deformation can cause air leakage at the exhaust plug in the production process, thereby causing the problem of waste cores.
(II) technical scheme
In order to achieve the purpose, the utility model is realized by the following technical scheme: the round hole vent plug comprises a hole surface and a ring surface, wherein the hole surface is arranged at the bottom of the ring surface, the hole surface is made of one of polyformaldehyde and glass fiber, and the ring surface is made of one of polyformaldehyde and glass fiber.
Preferably, the top surface of the hole surface is provided with a cross reinforcing rib, and the cross reinforcing rib is arranged at the bottom of the ring surface.
Preferably, the tail end of the cross reinforcing rib is provided with a reinforcing rib, and the reinforcing rib is connected with the inner wall of the annular surface.
Preferably, the material of the cross reinforcing rib is one of polyformaldehyde and glass fiber.
Preferably, the material of the reinforcing rib is one of polyformaldehyde and glass fiber.
Preferably, the hole surface is provided with holes.
Preferably, the top of the inner wall of the ring surface is provided with a matching ring groove.
(III) advantageous effects
The utility model provides a round hole vent plug. The method has the following beneficial effects:
(1) the round hole exhaust plug is made of POM polyformaldehyde and GF glass fiber materials, and the cost of the round hole exhaust plug is one fourth of the price of copper. In the actual operation production process, cost reduction is the first task. The utility model can reduce the cost of the vent plug by three quarters.
(2) The round hole vent plug is made of a novel material design, so that the round hole vent plug is not easy to deform in the production and use processes due to the characteristics of high hardness, high rigidity, high wear resistance and the like; meanwhile, due to the round hole design, sand and resin are not easy to block in the production process, exhaust is smooth and clean, the quality of the sand core is more stable, the replacement frequency of the exhaust plug is greatly reduced, and the production efficiency is improved.
