JPS5928823Y2 - Inner frame for gutter block molding - Google Patents

Description

[Detailed explanation of the idea] The present invention relates to an intermediate frame for forming side gutter blocks.

In conventional gutter blocks, the upper surface of which is widened into a tapered shape makes it easy for the middle frame to escape, but in the case of blocks with substantially vertical inner walls on both sides, it is difficult to escape the middle frame. Therefore, the inner frame was divided into several parts and connected with bolts, but it took time to assemble and disassemble the inner frame.

The present invention was devised in view of the above problems, and includes a pair of upper and lower mounting pieces protruding from the opposing side plate portions of a pair of cross-sectional split frames that form the middle frame body. The mounting pieces and the lower mounting piece are rotatably connected by upper and lower link pieces parallel to each other and inclined in the vertical direction, and by pulling up the split frame on the side where the link piece is higher, the other split frame is connected. The split frame can be easily removed from the molded product by rotating inward.

Next, the configuration of an embodiment of the present invention will be explained with reference to the accompanying drawings.

1 is the middle frame main body, and the side plate part 2 is a metal plate bent into a cross-sectional shape.
A pair of divided frames 4 consisting of a bottom plate portion 3 and a bottom plate portion 3 are arranged such that the side plate portions 2, 2 face each other and stand upright, and the bottom plate portions 3, 3 abut against each other at their tips.

Furthermore, a pair of upper and lower mounting pieces 5, 6, 7, and 8 are protruded from opposite positions of the side plate parts 2, 2, respectively, and the mounting piece 5 of one side plate part 2 is larger than the mounting piece 7 of the other side plate part 2. Also, the mounting pieces 6 are arranged slightly higher than the mounting pieces 8.

The upper opposing mounting pieces 5 and 7 and the lower opposing mounting pieces 6 and 8 are rotatably connected by mutually parallel link pieces 9 and 10, respectively.

One of the upper and lower link pieces 9, 10 has a high support shaft lL12,
The other support shafts 13 and 14 are pivoted at an angle so as to be lower.

Also, the distance between the support shafts 11.12° and 13.14 is t, 1. /,
21 The distance between the support shafts IL1312.14 is 13.1. Then, 11=t2. It is t3-t4.

Furthermore, an angle member 15 is provided inside the upper end of each side plate portion 2.
is fixed, and a lifting handle 16 is attached to the angle member 15 on the side where the link pieces 9, 100 are attached higher.

Further, the ends of the bottom plate parts 3, 3 are brought into contact with each other on an inverted tapered slope with the pulled-up side facing upward, and a presser piece 17 whose ends are fixed to the upper bottom plate part 3 is brought into contact with the upper surface of the abutting part. ing.

The link mechanisms consisting of the mounting pieces 5, 6, 7, 8 and the link pieces 9, 10 are arranged near both longitudinal ends of the middle frame body 1, respectively.

Further, both ends of the middle frame main body 1 are fitted into the stepped portions 19 of the end face support frame 18 to maintain their shape.

Next, the operation of the above embodiment will be explained.

The inner frame main body 1, whose inner end is supported by the end support frame 18.degree. 18, is housed in an outer frame (not shown), and a molded product a consisting of a gutter block is formed.

Next, grasp the handle 16 and pull up one of the split frames 4.
Since one end of the link piece 9.10 is pulled up, the link piece 9
The other ends of ゜10 rotate downward, and the mounting pieces 7 and 8 connected to the other ends of link pieces 9 and 10 rotate inward together with the other divided frame 4, and the divided frames 4 and 4 is peeled off from the inner surface of molded article a.

According to the present invention, a pair of divided frames each having a side plate part and a bottom plate part formed by bending in a cross-sectional shape are arranged so that the pair of said side plates face each other and stand upright, and the tips of said pair of bottom plate parts abut each other. A pair of upper and lower mounting pieces are provided at opposite positions of the pair of side plates, respectively, and the upper and lower mounting pieces are parallel to each other. Since the upper and lower link pieces, which are large and tilted in the vertical direction, are rotatably attached to each other, after molding, by pulling up one of the split frames on which the link piece is attached high from the molded product, the other end of the link piece can be attached to the other end. It rotates inward together with the split frame, and the pair of split frames can be easily peeled off from the inner surface of the molded product.
