The invention discloses a movable ejector pin type venting mold, which comprises a mold core body, a plurality of vent holes, movable ejector pins, a dust-removing plate and a return plate, the return plate, the dust-removing plate and the mold core body are tightly mounted sequentially from the top down, the mold core body is provided with the vent holes, which run through the mold core body, the dust-removing plate is provided with a dust-blowing and suction passage which communicates with the vent holes, the movable ejector pins which can extend and retract are arranged in the vent holes, and run through the return plate, the dust-removing plate and the mold core body, the dust-removing plate is also provided with a blowing and suction hole, one end of the blowing and suction hole communicates with a suction machine, and the other end of the blowing and suction hole communicates with the dust-blowing and suction passage. The structure of the movable ejector pin type venting mold is simple and reliable, and the cost is low; when the mold is closed, the air in a mold cavity can be rapidly exhausted out, and thereby the problem of how to exhaust the air when the mold is closed to produce a brick is solved.
Description
technical field [0001] The invention relates to the field of ceramic machinery, in particular to a movable thimble type exhaust mold. Background technique [0002] The ceramic brick forming mold is an important equipment for the production of ceramic bricks. The current ceramic bricks are formed by powder materials. The presence of trapped air in the fired ceramic tiles leads to the formation of serious defects in the ceramic product, which are usually only detected at a later stage of production, thus leading to the total rejection of the product with significant economic losses . In order to solve this problem, the existing ceramic tile forming molds are provided with a large number of special vent holes on the mold core body, but this kind of vent holes are used for natural exhaust during the production process, so the speed of exhaust gas is too high. Slow, affecting work efficiency; and a large amount of powder accumulated in the hole, prone to clogging, resulting in ...
