Abstract

The utility model discloses a movable thimble ceramic tile forming and exhaust mold capable of cleaning powder in exhaust holes and allowing all thimbles to move synchronously. The movable thimble ceramic tile forming and exhaust mold comprises a mold core body, wherein the exhaust holes communicated with a working face of the mold are formed in the mold core body; the anti-blocking thimbles capable of making telescopic motion are arranged in the holes; exhaust gaps are formed among the exhaust holes and the anti-blocking thimbles; outlets of the exhaust holes are blocked by the front end parts of the anti-blocking thimbles; powder blowing channels capable of blowing away the powder in the exhaust gaps are formed in side walls of the exhaust gaps; the mold core body is internally provided with a first air channel and a second air channel; the rear end parts of the anti-blocking thimbles are cap-shaped; a first air chamber is arranged on one side, facing toward the front end part, of the rear end part of each anti-blocking thimble and in the mold core body; a second air chamber is arranged on the other side, facing toward the front end part, of the rear end part of each anti-blocking thimble and in the mold core body; the first air chambers are communicated with the first air channel; and the second air chambers are communicated with the second air channel.

Description

A kind of movable top pin type Ceramic Tiles moulding vented mould

Technical field:

The utility model relates to a kind of movable top pin type Ceramic Tiles moulding vented mould.

Background technology:

The Ceramic Tiles mould is the industrial visual plant of Ceramic Tiles; Ceramic Tiles is the powder moulding; when the upper and lower mould matched moulds is beaten brick; because mould cooperates closely; inner air is difficult to timely discharge behind the matched moulds; make upper and lower mould matched moulds process produce powerful resistance; in order to address this problem; existing mould arranges a large amount of special-purpose steam vents at the core rod body, but this steam vent accumulates a large amount of powders in the process of producing because in the hole, occurs clogging easily; after causing production a period of time; usually need to shut down, the steam vent that stops up is carried out cleaning work, otherwise the Forming Quality of Ceramic Tiles and shaping speed can be subjected to great influence.

In order to solve above-mentioned blockage problem, the applicant has applied for " a kind of Ceramic Tiles mould that prevents that steam vent from stopping up " by name July 11 in 2011, the patent No. is the utility model patent of " 201120494362.2 ", utilize the stretching motion of anti-blocking thimble, the exhaust outlet that prevents steam vent stops up, but in daily use, when anti-blocking thimble ejects, can produce the slit between the tailstock barrel in itself and the steam vent, at this moment, powder can enter in the steam vent from this slit, influence the expanding-contracting action of anti-blocking thimble, in addition, the anti-blocking thimble in this patented technology is provided with a lot of bars, in the prior art, they all are difficult to realize synchronization action.

Summary of the invention:

The purpose of this utility model is in order to overcome the shortcoming of above-mentioned prior art, a kind of movable top pin type Ceramic Tiles moulding vented mould that can clear up powder in the steam vent automatically, hold concurrently all thimbles are synchronized with the movement to be provided.

For achieving the above object, the technical scheme that the utility model provides is: a kind of movable top pin type Ceramic Tiles moulding vented mould, include the core rod body, be drilled with the steam vent that is communicated with die-face in a large number on the core rod body, be provided with the anti-blocking thimble that to make expanding-contracting action in the hole, leave exhaust clearance between steam vent and the anti-blocking thimble, the leading section shutoff steam vent outlet of anti-blocking thimble, the sidewall of exhaust clearance be provided with can blow away powder in the exhaust clearance blow the powder passage, in the core rod body, be provided with first air flue and second air flue, the rearward end of anti-blocking thimble is the cap shape, in the core rod body, side towards leading section of anti-blocking thimble rearward end is provided with first air chamber, opposite side is provided with second air chamber, and first air chamber is communicated with first air flue, and second air chamber is communicated with second air flue.

After said structure improves, utilization is blown the powder passage powder in the steam vent is blown away, thereby the cleaning steam vent prevents that the existence because of powder from influencing the motion of anti-blocking thimble, in addition, by to the second air chamber air feed, all anti-blocking thimbles are ejected simultaneously, prevent that steam vent from stopping up, and to the first air chamber air feed, can make all anti-blocking thimble withdrawals, realize being synchronized with the movement of whole anti-blocking thimbles.

Description of drawings:

Fig. 1 is the structural representation of the utility model movable top pin type Ceramic Tiles moulding vented mould.

The specific embodiment:

Now elaborate the utility model by reference to the accompanying drawings:

The movable top pin type Ceramic Tiles moulding vented mould of present embodiment, include core rod body 1, be drilled with the steam vent 2 that is communicated with die-face in a large number on the core rod body 1, be provided with the anti-blocking thimble 3 that to make expanding-contracting action in the hole, leave exhaust clearance 4 between steam vent 2 and the anti-blocking thimble 3, leading section 31 shutoff steam vents 2 outlets of anti-blocking thimble 3, the sidewall of exhaust clearance 4 be provided with can blow away powder in the exhaust clearance 4 blow powder passage 5, in core rod body 1, be provided with first air flue 6 and second air flue 7, the rearward end 32 of anti-blocking thimble 3 is the cap shape, in core rod body 1, side towards leading section 31 of anti-blocking thimble rearward end 32 is provided with first air chamber 8, opposite side is provided with second air chamber 9, first air chamber 8 is communicated with first air flue 6, and second air chamber 9 is communicated with second air flue 7.

More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
