るものである。Conventionally, extrusion molding equipment for extruding self-hardening inorganic raw materials such as cement and gypsum together with reinforcing metal wires, etc. has been disclosed in Japanese Patent Publication No. 63-22082 and Japanese Patent Publication No. 56-360.
It is known as No. 44 etc. However, the above-mentioned special public service
The extrusion molding apparatus described in Publication No. 082 uses two extruders, a Y-shaped discharge pressure pipe, and a die, so it has drawbacks such as a large area occupied by the equipment and a high cost of the equipment. Not only that, but the viscosity and plasticity of the raw materials supplied to the two extruders mentioned above, as well as the balance of the extrusion eaves of the extruders, etc., must be exactly the same! This has the disadvantage that a homogeneous extrusion molded product cannot be obtained, and it has been difficult to use it industrially. Furthermore, the above-mentioned special public service
- In Publication No. 36044: c! i! The extrusion molding equipment developed in this way does not have enough consideration given to the guide body disposed in the discharge tube and the shape of the ejection tube itself, making it extremely difficult to produce homogeneous extruded products in large quantities industrially. The present invention was devised in view of the above-mentioned drawbacks of the conventional technology.
A detailed explanation will be given below according to examples. The extrusion molding apparatus M 14a according to the present invention is shown in FIG.
1 is attached with a curved bamboo-shaped discharge pipe 3 for displacing the extrusion direction of the extruder 2, and a mouthpiece 4 is attached to the tip 31 of the discharge pipe 3, which is the same as the conventional extrusion molding apparatus. Or, the discharge pipe 3 is a plane formed by two center lines a-b, a center line a parallel to the extrusion direction of the extruder 2 and a center line s parallel to the discharge direction of the discharge pipe 3. Up and down (first
The kite body 5 or the rear end 51 of the guide body 5 is fixed to the discharge pipe 3 by being clamped to the discharge pipe 3. As shown in FIG.
6 etc., and is further clamped and fixed via a holding plate 7,
One inner wall 32 of the discharge pipe 3 (lower or left inner wall in FIG. 33 toward the tip 31 that is approximately parallel to the discharge direction of the discharge pipe 3 (
The inner wall 34 facing the inner wall 32 (the inner wall on the upper or right side in FIG. 1) is formed into a large circular arc and is once bent from the vicinity of the rear end 33 parallel to the extrusion direction. After being bent over 90 degrees, the small arc touching the large arc finally bends the inner wall 34 by about 90', and the inner wall 34 is formed by combining two arcs, so that the extrusion direction of the extruder 2 A protruding cavity 8 is formed at a position crossing the inner wall 34, and a contact point 35 of the inner wall 34 is formed at the contact point 35 of the inner wall 34.
By making the small arc with the same radius as the arc of the inner wall 32, at least the inner walls 32 and 34 near the distal end 31 of the discharge pipe 3 are aligned with respect to the center line parallel to the discharge direction of the discharge pipe 3. Furthermore, at least the vicinity of the tip 52 of the kite body 5 has an outer shape symmetrical with respect to the center line parallel to the discharge direction of the discharge pipe 3, and is formed symmetrically as A. The tip of the guide body 5! The vicinity of Iti 52 is located on the tip 31 side of the contact 35 on the inner wall 34 of the discharge pipe 3.

The inner walls 36 and 37 of the discharge pipe 3 are at least close to the front fir 2 in the vertical direction with respect to the plane formed by the center line.
It is symmetrical from the contact point 35 to the tip 31 side, and the outer shape of the ζ body 5 near the tip 52 is also symmetrical. Take (
=1 is cut and the core 9 is attached (pull) as necessary.

成形品11は有するものとなる。When molding an inorganic raw material using the extrusion molding apparatus 1 as described above, the raw material is inputted from the input port (not shown) of the extruder 2, extruded by the extruder 2 into the discharge pipe 3, and The raw material is suddenly buried from the rear end 33 side, and the raw material that reaches the protruding space 8 so as to wrap around the kite body 5 fixed to the discharge pipe 3 is cured in a large arc of the inner wall 34 and extruded. The inner walls 32, 34, 36 of the discharge pipe 3 are displaced approximately 90' from the direction toward the discharge direction and proceed toward the distal end 31 of the discharge pipe 3.
37, the metal wire 10 supplied from the kite body 5 is further discharged from the tip 31 of the discharge tube 3 to the base 4, and from the tip 41 of the base 4, for example, The molded product 11 having the desired shape as shown in FIG. 3 is discharged with the metal wire 10 encased inside it, and if it has the core 9 as shown in FIGS. The molded product 11 has a cavity 12 that matches the shape of the core 9.

となく均質なものか得られるものである。The extrusion molding apparatus 1 of the present invention extrudes the molded product 11 using one extruder 2, so that it is possible to easily extrude the molded product 11 without requiring any skill such as finely adjusting the balance between the two extruders. Not only is the homogeneous molded product 11 removed, but after the inner wall 34 of the discharge tube 3 is once set to protrude in the extrusion direction of the extruder 2 to form the protruding cavity 8, the inner wall 32 immediately on the tip 31 side of the discharge tube 3 is
34, 36, 37 and the outer shape of the vicinity of the tip 52 of the guide body 5 facing the vicinity of the tip 31 of the discharge pipe 3 is vertically and horizontally symmetrical with respect to the center line parallel to the discharge direction of the discharge pipe 3 By forming the extruder 2 into a shape that
A part of the raw material extruded from the inner wall 3 of the discharge pipe 3
2 and extruded from the extruder 2 side of the kite body 5, while other raw materials are extruded from the protruding cavity 8 formed by the large arc of the opposing inner wall 34 along the inner wall 34. The raw material is extruded from the opposite side of the extrusion 1 and 2 of No.
Since the tip 31 side of the contact point 35 between the large circular arc and the small circular arc is formed completely symmetrically with respect to the center line 1) parallel to the discharge direction, including the outer shape of the kite body 5, the raw material is completely discharged. It is attached to the tip 31 of the discharge pipe 3 only by a force that is consistent with the discharge direction of the pipe 3 (it is extruded from the pulled mouthpiece 4, and the molded product 11 is deformed; it is homogeneous without slipping). This is what you can get.

Because they are clamped, if the metal wire 1'0 etc. coming out of the kite body 5 slips from the designed position due to the pressure of the raw material in the discharge pipe 3, or furthermore, if the kite body 5 itself shifts. etc., the position of the metal wire 10 can be easily adjusted by adjusting the bolts 6.

A groove 54 to which zero is supplied may be provided, and covers 55 may be fixed to cover the groove 54. Furthermore,
The outer shape of the kite body 5 is formed by extrusion.It is not preferable to form a surface perpendicular to the extrusion direction of the machine 2, as this will impede the flow of the raw material, and the side surface should be formed into a medium-thin side. or recommended.

Did I mention that the inner walls 32 and 34 on the side of the tip 31 from the contact point 31) of the discharge pipe 3 are formed of circular arcs with the same radius?
Each of 34 may be a straight line that touches the arc on the extruder 2 side from the contact point 35, in short, the tip 31 side from the contact point 35 is symmetrical with respect to a medium line parallel to the discharge direction of the discharge pipe 3. Something that is essential.
