After using the device, the mould has less abrasion even in the case of being used for a long time; in the using process of the mould, a small amount of the leaked gypsum paste can be automatically cleaned so as to realize the self-cleaning of the mould; with better sealing property of the mould, the gypsum hollow block finished product has higher surface smoothness and the defective index is reduced.

Description

Gypsum hollow block mould self-cleaning device

Technical field

The utility model relates to a kind of gypsum hollow block mould self-cleaning device.

Background technology

Gypsum hollow block is one of green structural material of wideling popularize of China recent years.For gypsum hollow block, existing certain mechanical performance requirement also has strict requirement to its size, precision and surfacing fineness simultaneously.

At present, the equipment of domestic production gypsum hollow block, be divided into two classes by the depanning mode difference of gypsum hollow block: a class is an on-mode, another kind of is the extruding ejecting type.

On-mode mainly is used in the production of manual production or simple and mechanicalization, and its labour intensity is big, production efficiency is low, poor product quality, unstable product quality, is now classified as superseded scope by the Ministry of Construction.

The extruding ejecting type now is the main flow mode of production, produce the equipment of gypsum hollow block under this mode, structure of equipped mold cleaning device is in it: the installing plate level places on the hollow support, two horizontal side plates, connect by securing member between two vertical end plates and surround a square cylinder, cylindrical shell is landed on the installing plate, N longitudinal baffle is set in the cylindrical shell its inner chamber is separated into N+1 die cavity, N is not less than 2 natural number, the lower end of each die cavity horizonal base plate that is slidingly matched, the some bars of finding time of longitudinal separation ground plug-in mounting on each base plate, the find time lower end of bar is shaped on external screw thread and connects with installing plate by securing member, the downside of each base plate is connected to two push rods that extend and run through installing plate downwards with vertically arranging, and each is found time between bar and the associated floor, all guarantee sealing between the chamber wall of each base plate and corresponding die cavity by machining accuracy.The operation principle of described equipment is: plaster of Paris (or reclaimed gypsum) is stirred into slurry, again slurry is poured in the square cylinder of vertical upper shed, after treating that the first coalescence of gypsum reaches certain intensity, by hydraulic transmission mode, drive base plate with push rod and rise, the gypsum hollow block finished product of moulding is ejected, then, by hydraulic transmission mode, drive base plate decline return again, wait for cast next time with push rod.Because each finds time between bar and the associated floor, only guarantee sealing by machining accuracy between the chamber wall of each base plate and corresponding die cavity, therefore, even mould is shorter service time, also can there be the bigger defective of wearing and tearing in it and problems such as a large amount of spillages, difficult cleaning occur, the sealing property of mould is relatively poor, this causes the gypsum sticking to mould serious, and the surface smoothness of gypsum hollow block finished product is more and more lower, percent defective rises.

The utility model content

Technical problem to be solved in the utility model provides a kind of gypsum hollow block mould self-cleaning device of producing in the gypsum hollow block equipment that is fitted in, after adopting this device, even mould is longer service time, its wearing and tearing are also less, and can in the mould use, clear up a small amount of gypsum slurry of leaking automatically, realize the self-cleaning of mould, the sealing property of mould is preferable, and this causes the surface smoothness of gypsum hollow block finished product higher, percent defective descends.

For solving the problems of the technologies described above, the utility model provides a kind of gypsum hollow block mould self-cleaning device, its structure is: the installing plate level places on the hollow support, two horizontal side plates, connect by securing member between two vertical end plates and surround a square cylinder, cylindrical shell is landed on the installing plate, N longitudinal baffle is set in the cylindrical shell its inner chamber is separated into N+1 die cavity, N is not less than 2 natural number, the lower end of each die cavity horizonal base plate that is slidingly matched, the some bars of finding time of longitudinal separation ground plug-in mounting on each base plate, the find time lower end of bar is shaped on external screw thread and connects with installing plate by securing member, the downside of each base plate is connected to two push rods that extend and run through installing plate downwards with vertically arranging, each finds time to seal by at least one O RunddichtringO between bar and the associated floor, seals by the quad seal circle between the chamber wall of each base plate and corresponding die cavity.

For can concise description for the purpose of the problem, below gypsum hollow block mould self-cleaning device described in the utility model be all abbreviated as this device.

This device is fitted in to be produced in the gypsum hollow block equipment, can use.

After adopting this device, the O RunddichtringO makes each find time to obtain excellent sealing between bar and the associated floor, the quad seal circle makes and obtains excellent sealing between the chamber wall of each base plate and corresponding die cavity, described two kinds of sealing rings all have bigger elasticity, at the backform of mould with return " to scrape " in the mold process and go to stick to respectively the small portion of residual gypsum slurry of finding time on bar and the die cavity chamber wall, therefore, even mould is longer service time, its wearing and tearing are also less, greatly reduce the possibility of spillage, and can in the mould use, clear up a small amount of gypsum slurry of leaking automatically, realize the self-cleaning of mould, the sealing property of mould is preferable, and this causes the surface smoothness of gypsum hollow block finished product higher, percent defective descends.

As optimization of the present utility model, the downside and the installing plate of described two horizontal side plates are affixed, and the downside of two vertical end plates and N longitudinal baffle all and between the installing plate leaves the gap and forms a horizontal setting chamber; The downside of arbitrary horizontal side plate is provided with N and puts in the placing chamber and position and N the corresponding one by one vertical water pipe of dividing plate difference, each water pipe is in that end sealing in the placing chamber, the other end of each water pipe gathers the back and is communicated with the water main, each water pipe axially offer some groups of water holes; Have the plasma discharge hole on the installing plate.

In the mould use automatically under the cleaning and fall into a small amount of gypsum slurry in the placing chamber, can be washed by the water in the water pipe, the mixed solution that washes away back formation is unified through the plasma discharge hole to be discharged and obtains to collect, thereby further improves the self-cleaning effect of mould.

Each water pipe axially offer one group of water hole by the mode of every interval 50mm, have in every group of water hole four along water pipe the circumferentially uniform and spray orifice of alternate an angle of 90 degrees each other.

So, will offer many groups water hole on each water pipe, like this, fall into a small amount of gypsum slurry in the placing chamber, can obtain by the water in the water pipe evenly, wash away fully up hill and dale, thereby further improve the self-cleaning effect of mould.
