Method of installing circuit member in resin-molded panel
View Patent ↗A method includes a first, a second and a third step, and a circuit member is installed in a resin-molded panel simultaneously when this resin-molded panel is vacuum formed. In the first step, the circuit member to be installed is placed on an upper surface of a circuit member-installing portion formed on and projecting from a front surface of a base mold. In the second step, a heated and softened panel material is laid on the front surface of the base mold. In the third step, the air between the panel material and the base mold is drawn via notch spaces and air-drawing holes.
1. A method of installing a circuit member in a resin-molded panel, comprising the steps of:
a first step of placing the circuit member to be installed on an upper surface of a circuit member-installing portion formed on and projecting from a front surface of a base mold of a vacuum forming mold;
a second step of laying, after said first step, a heated and softened panel material on said front surface of said base mold in a manner to cover at least a first surface of said circuit member placed on said upper surface of said circuit member-installing portion; and
a third step of drawing, after said second step, the air between said panel material and said base mold via a notch space, formed by cutting upper and side surfaces of said circuit member-installing portion, and an air-drawing hole formed in said base mold and communicating with said notch space, thereby forming retaining portions which project into the notch space by drawing and fitting the heated and softened panel material around side surfaces of the circuit member and at least a portion of a second surface of the circuit member, which is opposed to the first surface;
wherein said circuit member is installed in the resin-molded panel simultaneously when said resin-molded panel is vacuum formed.
2. A method of installing a circuit member in a resin-molded panel according to claim 1 , wherein before said second step, a circuit member-holding member, which is separate from said circuit member-installing portion, is attached to said circuit member-installing portion to prevent the lifting of said circuit member.
3. A method of installing a circuit member in a resin-molded panel, comprising the steps of:
a first step of placing the circuit member to be installed on an upper surface of a circuit member-installing portion formed on and projecting from a front surface of a base mold of a vacuum forming mold;
a second step of laying, after said first step, a heated and softened panel material on said front surface of said base mold in a manner to cover at least a first surface of said circuit member placed on said upper surface of said circuit member-installing portion; and
a third step of drawing, after said second step, the air between said panel material and said base mold via a step space, formed by a step between an axial end of said circuit member-installing portion and said base mold, and an air-drawing hole formed in said base mold and communicating with said step space, thereby forming retaining portions which project into the step space by drawing and fitting the heated and softened panel material around side surfaces of the circuit member and at least a portion of a second surface of the circuit member, which is opposed to the first surface;
wherein said circuit member is installed in the resin-molded panel simultaneously when said resin-molded panel is vacuum formed.
4. A method of installing a circuit member in a resin-molded panel according to claim 3 , wherein before said second step, a circuit member-holding member, which is separate from said circuit member-installing portion, is attached to said circuit member-installing portion to prevent the lifting of said circuit member.
5. A method of installing a circuit member in a resin-molded panel, comprising the steps of:
a first step of placing the circuit member to be installed on a front surface of a base mold of a vacuum forming mold astride a recess formed in said front surface of said base mold;
a second step of laying, after said first step, a heated and softened panel material on said front surface of said base mold in a manner to cover at least a first surface of said circuit member; and
a third step of drawing, after said second step, the air between said panel material and said base mold via said recess and an air-drawing hole formed in said base mold and communicating with said recess such that a portion of the panel material is drawn into the recess so as to form retaining portions in the heated and softened panel material which are fitted in the recess space and cover at least a portion of a second surface of the circuit member, which is opposed to the first surface;
wherein said circuit member is installed in the resin-molded panel simultaneously when said resin-molded panel is vacuum formed.
6. A method of installing a circuit member in a resin-molded panel according to claim 1 , wherein said air-drawing hole is formed immediately below said notch space in said base mold.
7. A method of installing a circuit member in a resin-molded panel according to claim 1 , wherein said circuit member-installing portion projects a predetermined height and has a width substantially identical to a width of the circuit member.
8. A method of installing a circuit member in a resin-molded panel according to claim 1 , wherein said notch space is formed on opposite sides of a predetermined position of said circuit-member installing portion.
9. A method of installing a circuit member in a resin-molded panel according to claim 1 , wherein said notch space is formed so as to traverse a predetermined position of said circuit-member installing portion.
10. A method of installing a circuit member in a resin-molded panel according to claim 3 , wherein said air-drawing hole is formed immediately below said step space in said base mold.
