CN2302880Y - Inner mould with multiple row of holes for machine for extruding wall sheet - Google Patents

Abstract

The utility model relates to an improved extruding inner mold of a wallboard extruder. The arrangements of a material guide pipe and a material feeding threaded rod are the same to the prior art. The utility model has the improved proposal that a set of mold rods is extended out from the end surface of the material guide opening. The set of mold rods comprises six mold rods. The mold rods are divided into two rows top and bottom and are fixed to bisecting lines arranged between every two material feeding threaded rod holes. The set of mold rods can also be tight fixed to a corresponding shaft which passes through the material feeding pipe body, and thus not only the cross-section of the extruded wallboard is provided with lightening holes extracted by the material feeding threaded rod, but also the cross-section of the extruded wallboard can be provided with two rows of holes extracted by the mold rods. Thus the weight bearing capability of the wallboard can be decreased to the level which is prior to the standard value.

Description

Many rounds internal mold of wallboard extruder

The utility model relates to a kind of internal mold of extruding of the annex that contains the cement products process equipment, especially the wallboard extruder that has improved.

Chinese patent ZL95239465.0 discloses a kind of " feed system of improved Light trabs make-up machine ", notification number is CN2225508Y, the day for announcing to be on April 24th, 1996, and the main parts size passage of this feed system and one group of feeding spiro rod have constituted the internal mold of extruding of wallboard extruder.The shape that the forming cavity that is surrounded by this internal mold and limit mould, top board, place is extruded the wallboard section is that row's lightening core is arranged in the middle of the rectangle, this can obtain well to alleviate effect to the thin plate of producing below the 10mm, and it is little owing to rectangular aspect ratio for slab, the number of lightening core reduces, and the unit weight of plate is very high with making.

The purpose of this utility model is improved the internal mold that has the wallboard extruder now, makes it when extruding slab abundant lightening core can be arranged, and the unit weight of wallboard can be reduced to below the standard value.

For achieving the above object, the utility model adopts following technical scheme, the setting of passage and feeding spiro rod and cooperatively interact same as the prior art, promptly have charging aperture to be communicated with the feeding spiro rod hole that all front and back connect above the passage body, institute is improved to be to stretch out one group of tringle by the material guide port end face.

This group tringle has 6, and is divided into two rows and is fixed on two bisectors between per two feeding spiro rod holes.The structure of this group tringle also can be to be fastened on the axle of the correspondence of passing the passage body, and the axle other end is provided with the friction pulley that contacts with feeding spiro rod, and every axle is connected with passage rear end face and material guide port end face by two bearings.

By above scheme as seen, owing to set up two row's tringles, make the lightening core that not only has feeding spiro rod to extract out on the wallboard section of extruding, the hole that also has two row's tringles to extract out makes the unit weight of wallboard can drop to the level that is better than standard value.

Description of drawings:

The structural representation of Fig. 1 embodiment one;

Fig. 2 is the left view of Fig. 1;

The structural representation of Fig. 3 embodiment two;

Fig. 4 is the A-A cut-away view of Fig. 3.

The utility model is described in further detail below in conjunction with two embodiment and accompanying drawing thereof:

Embodiment one, referring to Fig. 1, Fig. 1 is the front view of internal model structure, omitted the otic placode that the passage both sides connect with frame among Fig. 1, also omitted the feeding spiro rod in four feeding spiro rod holes 2, because 6 tringles 3 are that relative passage body 1 is fixing in this example, promptly tringle 3 is welded on the passage body 1 material guide port end face, so the section of tringle 3 makes bigger trapezoidal of area.Referring to Fig. 2, receiving hopper on the charging aperture 4 of passage body 1 top, down and feeding spiro rod hole 2 UNICOMs, the length that tringle 3 stretches out should be able to be approximately and the hole-pumping tube of feeding spiro rod front end flush.

Embodiment two, referring to Fig. 3, Fig. 3 is the front view of internal model structure, omitted the otic placode that the passage both sides connect with frame among Fig. 3, also omitted the feeding spiro rod in four feeding spiro rod holes 2, because 6 tringles 3 are to rotate relative to passage body 1 in this example, promptly the section of tringle 3 is circular.Referring to Fig. 4, receiving hopper on the charging aperture 4 of passage body 1 top, down and feeding spiro rod hole 2 UNICOMs, the length that tringle 3 stretches out should be able to be approximately and the hole-pumping tube of feeding spiro rod front end flush.Axle 7 passes passage body 1 and by bearing 6 and bearing 8 supportings, its end and tringle 3 at the material guide port end face is fastening, other end dress friction pulley 5, and friction pulley 5 compresses with feeding spiro rod, rotates relative to passage body 1 thereby make tringle 3 can obtain power.

Claims (3)

1, many rounds internal mold of wallboard extruder, the top of passage body (1) have charging aperture (4) to be communicated with whole feeding spiro rods hole (2) that front and back connect, and it is characterized in that: stretch out one group of tringle (3) by the material guide port end face.

2, many rounds internal mold of wallboard extruder according to claim 1 is characterized in that: described one group of tringle (3) has 6, and is divided into two rows and is fixed on the bisector between per two feeding spiro rod holes (2).

3, according to many rounds internal mold of the described wallboard extruder of claim 1, it is characterized in that: described one group of tringle (3) is fastened on the axle (7) of the correspondence of passing passage body (1), axle (7) other end is provided with the friction pulley (5) that contacts with feeding spiro rod, and axle (7) is connected with passage rear end face and material guide port end face with bearing (8) by bearing (6).
