Abstract

A mold for molding a case of a mobile device includes a first, second, third, fourth and fifth main body, connection slide blocks, and first and second abutment slide blocks. The connection slide blocks and the second abutment slide blocks are inlaid in first and second slide channels of the first and second main bodies. The first abutment slide blocks are inlaid in channels of the connection slide blocks. The third, fourth and fifth main bodies are horizontally movable relative to the first and second main bodies. The first and second main bodies, the connection slide blocks and the first and second abutment slide blocks together define a male mold section and the third, fourth and fifth main bodies together define a female mold section. A metal thin sheet is placed on the male mold section and pressurized and molded by the female mold section to form the case.

First claim

What is claimed is:

1. A mold for molding a case of a mobile device, comprising:
a first main body having an upper side and a lower side, a periphery of the first main body having multiple first slide channels;
a second main body correspondingly disposed under the lower side of the first main body, multiple second slide channels being formed on four corners of the second main body and correspondingly extending to four corners of the first main body;
multiple connection slide blocks respectively correspondingly inlaid in the second slide channels and slidable relative to the first and second main bodies, each connection slide block having a channel;
a third main body correspondingly disposed on a right side of the first main body and horizontally movable relative to the first main body, the third main body having a first arched recess on one side adjacent to the first main body;
a fourth main body correspondingly disposed on a left side of the first main body and horizontally movable relative to the first main body, the fourth main body having a second arched recess on one side adjacent to the first main body;
a fifth main body correspondingly disposed on a front side of the first main body and horizontally movable relative to the first main body, the fifth main body having a third arched recess on one side adjacent to the first main body;
multiple first abutment slide blocks respectively correspondingly inlaid in the channels of the multiple connection slide blocks and slidable relative to the first and second main bodies;
multiple second abutment slide blocks respectively correspondingly inlaid in the first slide channels, the first and second main bodies and the connection slide blocks and the first and second abutment slide blocks together defining a male mold section, the third, fourth and fifth main bodies together defining a female mold section, the male and female mold sections being connectable with each other to form a mold cavity.

2. The mold for molding a case of a mobile device as claimed in claim 1 , wherein the first and second main bodies further have multiple through holes and multiple push pins, the through holes being positioned in alignment with each other, the push pins being respectively correspondingly fitted in the through holes of the first and second main bodies.

3. The mold for molding a case of a mobile device as claimed in claim 1 , wherein each connection slide block has the form of a rectangular triangular hexahedron body.

4. The mold for molding a case of a mobile device as claimed in claim 1 , wherein the first main body is a trapezoid hexahedron body.

5. The mold for molding a case of a mobile device as claimed in claim 1 , wherein each first abutment slide block has an abutment section and an insertion section respectively disposed on outer edge and inner edge of the first abutment slide block, the insertion section having a restriction protrusion block near a bottom side of the first abutment slide block, the abutment section on an outer edge of the first abutment slide block having the form of a convex face, the second abutment slide blocks being respectively correspondingly inlaid in the first slide channels of the first main body, each second abutment slide block having an abutment section and an insertion slide section respectively disposed on outer edge and inner edge of the second abutment slide block, the insertion slide section having a restriction protrusion section near a bottom side of the second abutment slide block, the abutment section on an outer edge of the second abutment slide block having the form of a convex face, the abutment sections of the first and second abutment slide blocks corresponding to the first, second and third arched recesses of the third, fourth and fifth main bodies.
