See Fig. 5, the lower surface of the upper substrate 51 of blanket 5 is leaned against on the elastomeric element 4 of counterdie 2 towards the lower left, and each rear and front end 50mm apart from counterdie 2 of the rear and front end of blanket 5; Because the supporting role of elastomeric element 4; The lower surface of the upper substrate 51 of blanket 5 contacts with the right lower quadrant on the 3rd plane 22 of counterdie 2; The angle on the 3rd plane 22 of the lower surface of upper substrate 51 and counterdie 2 is 15 °, thereby the acute angle ψ of the angle of the lower surface of upper substrate 51 and horizontal plane is 45 °.The lower body 52 of blanket 5 is positioned at the upper right side of the head portion breach 21 of counterdie 2.The upright plane 51-3-1 of the extension 51-3 of upper substrate 51 contacts with the top of second side 23 of counterdie 2, and the last plane of the upper substrate 51 of blanket 5 is towards the upper right side.
The head 71 of positions composition stair bar sheet material substrate 7 of the lower body 52 of above-mentioned blanket 5 and its top upper substrate 51 correspondences; The right end portion of the main part 51-2 of upper substrate 51 becomes the main part 72 of substrate 7; The extension 51-3 of upper substrate 51 becomes the extension 73 of substrate 7, during actual the use, and as required can also be shown in figure 10; On extension 73, offer tenon or groove, to adapt to and being used of other floors.
Present embodiment also can be with being the above-mentioned blanket 5 that forms with the two boards adhesion of integrated blanket replacement; But the integral type blanket is to obtain through on an integral plate, cutting away a cuboid piece; This mode material loss in actual use is bigger, and cost is higher.
2. see Fig. 6, placing gum dipped paper 61a and abrasion-proof paper 62a successively on the plane on the upper substrate 51 of blanket 5, and make the lower end abutment of gum dipped paper 61a and abrasion-proof paper 62a on the plane up and right side wall that stop breach 24 of counterdie 2; Wherein gum dipped paper 61a and abrasion-proof paper 62a's is big or small identical; Gum dipped paper 61a and abrasion-proof paper 62a are referred to as veneer paper 6a; The gum dipped paper 61a that adopts in the present embodiment is the facing paper through the resin dipping, and various patterns can be printed in the facing paper surface, and said resin is a melmac; Abrasion-proof paper 62a forms through the melmac dipping for the surperficial or inner wear-resisting body paper of having the cloth alundum (Al.Used gum dipped paper 61a is that the article number that bold and unconstrained ornament materials Co., Ltd produces in the Changzhou is the woodgrained paper of H68168 in the present embodiment, and used abrasion-proof paper 62a is that every weight per square meter that bold and unconstrained ornament materials Co., Ltd produces in the Changzhou is the abrasion-proof paper of 33g.
Abrasion-proof paper 62a covers on the gum dipped paper 61a, and the bond length of gum dipped paper 61a equals or be slightly larger than the bond length sum of lower surface of arc length and extension 52-2 of the 52-1 of round end portion of arc length and lower body 52 of bond length, the 51-1 of round end portion on last plane of arc length, main part 51-2 of corner subsidence part 51-4 of the upper substrate 51 of blanket 5.
Above-mentioned gum dipped paper 61a and these two pieces of paper of abrasion-proof paper 62a also can be replaced by a spray drawing; Said spray drawing has also played wear-resisting effect when playing decoration function, thus present embodiment also can use bold and unconstrained ornament materials Co., Ltd produces in the Changzhou article number as the spray drawing of H2232 as veneer paper 6a.
3. start press, make counterdie 2 upwards liftings, matched moulds is hot-forming then.Blanket 5, gum dipped paper 61a and abrasion-proof paper 62a form behind the idiosome in the right side area of the section of overlaying 32 that is introduced into spring clip mould 3 in company with the rising of counterdie 2, and this moment, position, the left side pressurized of gum dipped paper 61a and abrasion-proof paper 62a pasted sections 32 active force and to the round end bending of the blanket that is positioned at the right side 5.Along with the further rising of blanket 5, the cavity surface of the section of the overlaying 32 contact counterdies 2 of spring clip mould 3; Counterdie 2 continues to rise, and idiosome gets in the die cavity of patrix 1, and the section of overlaying 32 is also moved to the lower surface of the lower body 52 of blanket 5 along the semi-cylinder surface of the round end of blanket 5.
See Fig. 7; When patrix 1 and counterdie 2 matched moulds put in place; The part of blanket 5 fits tightly through the die cavity section 31 of veneer paper 6a and spring clip mould 3 and the section of overlaying 32 that has fitted tightly on counterdie 2, the remainder of the outer surface of blanket 4 directly and the 3rd plane 22 of counterdie 2 and second side 23 of counterdie 2 fit tightly; Wherein: also fit tightly each other in the first arc lamellar body 31-1 that the extension 52-2 of round end and lower body 52 that has the blanket 5 of veneer paper 6a is in spring clip mould 3 and the section of the overlaying 32 formed claddings; The last plane of the main part 51-2 of upper substrate 51 has the appropriate section of veneer paper 6a and the side plane section 31-2 of spring clip mould 3 fits tightly each other; The corner subsidence part 51-4 of blanket 5 has the appropriate section of veneer paper 6a and the second arc lamellar body 31-3 of spring clip mould 3 fits tightly each other; Not not fitted tightly each other of the upper substrate 51 of blanket 5 by the 3rd plane 22 of the part of lower body 52 coverings with counterdie 2; Second side 23 of the upright plane 51-3-1 of the extension 51-3 of the upper substrate 51 of blanket 5 and counterdie 2 fits tightly each other.
Though the die cavity that above-mentioned patrix 1 is formed during with counterdie 2 matched moulds is identical with blanket 4, and formally add the size that spring clip mould 3 setting in man-hour has reduced die cavity, make the profile of blanket 4 in theory greater than the size of die cavity; But because the blanket of handling 4 has slight plasticity by density board machine-shaping, and spring clip mould 3 0.5 millimeters thick only; Almost can ignore; When therefore counterdie 2 made progress the lifting matched moulds, under external force, negligible slight compression took place in blanket 4; Still can in the mold cavity that comprises spring clip mould 3, hot pressing overlay, overlay effect and reach instructions for use fully.
