Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to an apparatus for forming a heat insulating panel formed by foam-filling a heat insulating core material between a pair of face plates.

[Conventional technology]

Conventionally, when forming this type of insulation panel, as shown in FIG. After arranging the four liners e, e... that hold the body d, a heat insulating core material f such as foamed polyurethane is foam-filled between the surface plates b and b to improve the adhesiveness of the heat insulating core material f. A method has been adopted in which the surface plates b, b, the frame body d, and the heat-insulating core material f are integrally formed using the heat-insulating core material f.

[The problem that the idea aims to solve]

In this case, liner e and surface material b are connected with adhesive tape g
At the same time, a protrusion h for fixing the liner e is arranged on the outer side of the liner e, but the foaming pressure of the insulating core material f causes the liner e to collapse as shown in Fig. 4. As a result, the frame body d collapses, the surface plate b bulges and deforms, resulting in defective panels, resulting in a decrease in productivity. In addition, the jig setting position and setting man-hours are constant, resulting in a decrease in productivity.

[Means to solve the problem]

This invention was made with the intention of solving the above problem, and is a forming device for a heat insulating panel formed by foam filling a heat insulating core material between a pair of face plates, in which a pair of face plates holding the face plates is formed. a base, four liners that hold a frame formed around the four peripheries of the heat insulation panel, and a plurality of clamps that hold the outer surfaces of the liners on at least two adjacent sides, and the heat insulation panel is attached to one of the bases. A heat insulating panel forming device that provides a group of attachment holes consisting of two or more rows or two or more types of hole spacing along the vertical and horizontal directions of the panel, and allows the clamp to be selectively installed in any attachment hole. This is what we propose.

[Effect]

In the above-described structure of this invention, the number of clamps to be installed to hold the liner can be increased or decreased depending on the thickness of the insulation panel, or the installation position can be moved along the length direction to obtain the desired size of the panel. In addition, the liner is prevented from collapsing and deformation of the panel is eliminated, and the number of man-hours required for setting the jig is optimized to improve productivity.

〔Example〕

An embodiment of this invention will be described below based on FIGS. 1 and 2.

FIG. 1 shows a cross-sectional view when molding one heat insulating panel, and shows substrates 2 and 2' formed of a pair of plywood boards holding a pair of face plates 1a and 1a constituting the heat insulating panel 1. and 4 for holding each of the frames 1b, 1b... constituting the four circumferences of the heat insulating panel 1.
one liner 3, 3... and a plurality of clamps 4, 4 that hold the outer surfaces of the liners 3, 3 on two adjacent sides.
... and the fixing protrusion 8 constitute the main part of the molding device, and during actual molding, a plurality of heat insulation panels 1, 1 are stacked in multiple stages with these members stacked in multiple stages.
... are being formed at the same time.

The clamp 4 is a well-known type in which a handle 4c using a crank mechanism and a pressing piece 4d are supported between a pair of brackets 4b, 4b standing upright on a mounting board 4a. A heat insulator having a predetermined size and shape installed by fitting it into a receiving metal fitting 6 forming a plurality of mounting holes 5, 5'... provided at appropriate locations on one side of the base plate 2' on the lower side. It is designed to be compatible with Panel 1. In other words, in the base 2', there are at least two rows (two rows are shown in the drawing) in the direction along the liners 3, 3 on two adjacent sides (one vertical side and one horizontal side of the insulation panel 1). Mounting hole groups 5, 5 are drilled, and the mounting hole groups 5, 5 are drilled according to changes in the vertical and horizontal dimensions of the heat insulating panel 1.
... can be set, and the number of clamps 4 can be arbitrarily selected according to the foaming pressure of the insulating core material 1c as the thickness of the insulating panel 1 changes. As shown in FIG. 2, each clamp 4 selected in this manner has its insertion leg 4e projecting from the lower surface of the clamp 4 inserted into the mounting hole 5'. In this case, the mounting hole 5' may be circular or square, and the clamp can be stably installed by providing a key or keyway in either the mounting hole 5' or the insertion leg 4e. . The upper flange 7 of the receiving fitting 6 further forms a predetermined mounting hole 5'.
It is expected that the position of the clamp 4 will be more securely fixed if a screw hole is provided in the screw hole and the receiving metal fitting 6 is fastened to the base 2' through this screw hole.

Note that the liner 3 on the side opposite to the liner 3 held by the clamp 4 is held by a fixing protrusion 8 erected relatively high, or by a fixing protrusion 8 protruding from the upper and lower bases 2, 2'. The liner 3, which is held by the service ridges 8, 8 and also by the clamp 4, is adhered to the upper surface plate 1a with adhesive tape 9 so as not to separate from it, and is further held by the clamp 4.
A blind plug 10 is provided in the mounting hole 5' in which no mounting hole 5' is installed to prevent the upper surface of the base 2' from interfering with molding.

In the molding apparatus of this invention configured as described above, one of the surface plates 1a, 1a is placed on the lower base 2', and the other surface plate 1a is placed by assembling the frames 1b, 1b... After that, the liners 3, 3... are arranged around the four circumferences of the frames 1b, 1b..., and at this time, the liners 3, 3... on two sides are aligned with the fixed protrusions 8, 8, and the remaining two Side liner 3,
3 is fitted into the mounting hole 5' of the predetermined mounting hole group 5, and the clamps 4, 4... are fixed in position from the vertical and horizontal directions of the heat insulating panel 1, and the four circumferences are fixed. After setting each stage, insulating core material 1 is inserted from the injection port (not shown) toward between both surface plates 1a, 1a between the bases 2, 2 of each stage.
After a certain period of time, the clamp 4 is released and the bases 2, 2' and the liner 4,
4... is removed, and then the molded heat insulating panel 1 is taken out.

[Effect of idea]

As explained above, according to the molding device of this invention, the liner that holds the frame of the insulation panel is fixed in position with a clamp, so the liner collapses due to foaming pressure and the surface plate bulges and deforms. In addition, the installation position of the clamp can be selected according to the vertical and horizontal dimensions or shape of the panel, and the number of clamps can be prepared according to the foaming pressure, so the same device can be used. It is possible to form panels of various sizes using a machine, and the number of jigs set can be reduced, so excellent effects such as improved productivity can be obtained, and the value of its use is remarkable. It is.
