Abstract
The utility model relates to a mould venting thimble structure and technically aims to provide the mould venting thimble structure with smooth venting function and an unblocked venting tube. The mould venting thimble structure comprises a main thimble body, a venting cavity is reserved in the main thimble body, a strip shaped hole is reserved at the upper end of the main thimble body, the venting cavity is communicated with the external of the thimble through the strip shaped hole, a venting through hole is arranged on the lower portion of the main thimble body, and the venting cavity is communicated with the venting through hole. By the aid of the mould venting thimble structure, exhaust air in a mould cavity of a mould can be vented, the venting strip shaped hole is not prone to be blocked and does not need time to clean, and production efficiency is improved. The mould venting thimble structure is applicable to the moulds.
Description
Technical field
The utility model relates to a kind of mould thimble, in particular, relates to a kind of exhaust thimble structure that is applied in the mould.
Background technology
In the prior art; Die casting in process of production can process gas; Gas existence in its mould has influence on product quality, and this just requires in thimble, to be provided with exhaust structure, to accomplish mould the exhaust technique problem in the production process is arranged; Current mould when the exhaust thimble is set steam vent to be set as the major technique means; But the problem that these structures exist is in use, steam vent easy blocking and then influence normal exhaust, and this is further the quality of production that has influence on product just.The technological deficiency that the exhaust thimble structure of mould exists in the prior art becomes those skilled in the art's technical problem anxious to be solved.
Summary of the invention
The technical purpose of the utility model is to overcome in the prior art, and the mould thimble exists in exhaust and is prone to stop up and the not smooth technical problem of exhaust; Provide that a kind of exhaust is unimpeded, the nonclogging die venting thimble structure of blast pipe.
For realizing above technical purpose, the technical scheme of the utility model is:
The die venting thimble structure is characterized in that: include the thimble main body, be provided with exhaust cavity in the said thimble main body, in the upper end of said thimble main body, be provided with the exhaust bar hole, it is outside that said exhaust cavity is communicated with thimble through the exhaust bar hole; Said thimble main body below is provided with ventilative through hole, and exhaust cavity is communicated with ventilative through hole.
Further, said exhaust cavity is a cylindrical structure.
Further, said ventilative through hole is circular.
In the application of the utility model, said exhaust bar hole is communicated with the die cavity of mould, and exhaust cavity is communicated with ventilative through hole, and the gas in the die cavity gets into the exhaust cavity in the thimble main body through the exhaust bar hole, from ventilative through hole, discharges.
The useful technique effect of the utility model is: through said structure; The die cavity waste gas of the discharge mould that the utility model ability is unimpeded; The exhaust bar hole is difficult for stopping up, and does not need cleaning consuming time during use, has improved production efficiency; Also improved product quality, the utility model is simple in structure, with low cost, easy to implement.
Description of drawings
Fig. 1 is the structural representation of an embodiment of the utility model.
The specific embodiment
In conjunction with Fig. 1, specify the specific embodiment of the utility model, but claim is not done any qualification.
In Fig. 1, the die venting thimble structure includes thimble main body 100, is provided with exhaust cavity in the said thimble main body 100, and said exhaust cavity is a cylindrical structure.In the upper end of said thimble main body 100, be provided with exhaust bar hole 101, it is outside that said exhaust cavity is communicated with thimble through exhaust bar hole 101; Said thimble main body below is provided with ventilative through hole 102, and exhaust cavity is communicated with ventilative through hole 102.Said ventilative through hole 102 is circular.In application, said exhaust bar hole 101 is communicated with the die cavity of mould, and the exhaust cavity that the gas in the die cavity gets in the thimble main body through exhaust bar hole 101 is discharged from ventilative through hole 102.
The utility model exhaust bar hole be difficult for to stop up, and does not need cleaning consuming time during use, has improved production efficiency, is the not only practical but also novel technological improvement of one of this area.
