Mold for molding a mobile device casing

A mold for forming a mobile device casing, in particular a mold for forming a casing of a mobile device.

The current mobile devices such as handheld mobile phones and tablet PCs provide faster and faster computing power, and the relative heat generated by the internal devices of the mobile device is also higher, whether through the uniform temperature plate. Or the heat transfer potential of the heat pipe or the graphite sheet must guide the heat to the outside of the device for heat release. Some mobile device manufacturers use plastic or other non-metal materials to manufacture the casing of the handheld device for the appearance of the texture or the appearance of the mobile device.

It has been confirmed by experiments that the anti-heating of the handheld device still has a better heat dissipation effect for the metal casing, and the casing of the hand-held device for manufacturing the metal material mainly performs the cutting processing of the metal block through the CNC processing tool, thereby obtaining a thin metal. The outer casing, and the cutting or shuffling processing through the CNC processing machine, as the name implies, is to remove the unnecessary parts of the material by the material removal method, thereby obtaining the desired product, and it takes a considerable time to perform the cutting and material removal processing. In turn, the cost increase in working hours is generated, and the selection of the cutting tool and the loss of the tool during the cutting are also considerable problems in processing cost consideration.

Furthermore, the purchase of CNC processing equipment is the most important cost of production, because multi-axis CNC machining tools are much more expensive than other CNC machining tools, and the operators must write The processing program and the knowledge of operating CNC machining tools, the training operator is also another personnel cost to be considered. The multi-axis CNC machining tools are quite sophisticated and complex, and the maintenance cost is also high.

In addition, CNC machining tools must use a large amount of scraping agent to cool down during the cutting process, and some of the scraping agents can not be recycled and recycled, which will cause pollution to the environment.

Therefore, how to improve the process and thus save manufacturing costs is the goal of the person to be improved.

There are also attempts by the manufacturer to manufacture a hand-held device casing by a stamping process, but the inability to extract and return material for a relatively complicated structure such as a structural design having rounded corners or curved surfaces cannot be overcome.

At this stage, the plastic casing is still manufactured by injection molding, or the metal casing is processed by CNC processing equipment as the mainstream of the process. However, if a metal casing having both texture and better heat dissipation performance is desired, how to improve the process can greatly reduce the manufacturing cost. The primary focus of the people who want to improve.

The main object of the present invention is to provide a mold for molding a mobile device casing that can realize a metal casing for manufacturing a mobile device by molding.

A further object of the present invention is to provide a mold for molding a mobile device casing that saves manufacturing costs.

In order to achieve the above object, the present invention proposes a mold for molding a mobile device casing, comprising: a first body, a second body, a plurality of connecting sliders, a third body, a fourth body, a fifth body, a plurality of first top sliders, and a plurality of second a top slider; the first body has an upper side and a lower side, and the first body circumference has a plurality of first sliding slots; the second body is correspondingly disposed on a lower side of the first body, and the second The body of the body has a plurality of second sliding slots, and the second sliding slots are correspondingly extended to the four sides of the first body; the connecting sliders are respectively embedded in the second sliding slots, and the first sliding slot The two bodies are slidably correspondingly, and the connecting sliders have a groove portion; the third body is oppositely disposed on the right side of the first body, and is horizontally movable relative to the first body, opposite to the first body One side has a first curved recess; the fourth body is oppositely disposed on the left side of the first body, and is movable horizontally relative to the first body, and has a second curved recess on a side of the first body The fifth body is oppositely disposed on the front side of the first body, and is movable in a horizontal direction relative to the first body, and has a third arcuate recess on a side of the first body; the first abutting slider Correspondingly embedded in the groove portions And corresponding to the first and second body sliding; the second abutting sliders are respectively embedded in the first sliding slot, wherein the first and second bodies and the connecting sliders and the first And the second abutting slider jointly defines a male die, and the third, fourth, and fifth bodies collectively define a female die, and the male die and the master die are combined with each other to form a cavity.
