Description

Router shell and quick refrigerated forming die thereof

Technical Field

The invention relates to the technical field of router equipment, in particular to a router shell and a forming die for rapidly cooling the router shell.

Background

The router is a hardware device connecting two or more networks, functions as a gateway between the networks, is a special intelligent network device which reads an address in each data packet and then determines how to transmit, performs network layer relay and layer three relay tasks in OSI/RM, and performs storage and packet forwarding processing on the data packets between different networks, which mainly separates the networks in different logics.

The existing router is inevitably limited by the position of the existing socket when in use, and has to be placed on the ground, and the traditional router is provided with a plurality of openings, so that moisture is easily absorbed when placed on the ground, internal electronic devices are corroded, and the service life of the router is greatly shortened. Meanwhile, the existing router shell needs to spend a long time for shaping after being injected by a mold, so that the production efficiency is reduced. Therefore, the router shell and the forming die for rapidly cooling the router shell are provided.

Disclosure of Invention

The present invention is directed to a router housing and a mold for rapid cooling thereof, so as to solve the problems mentioned above in the background art.

In order to achieve the purpose, the invention provides the following technical scheme:

a router shell comprises a shell body, wherein the shell body comprises an upper shell and a lower shell, clamping grooves are uniformly preset in the positions of the front side, the rear side, the left side and the right side of the upper shell, a convex block is integrally connected with the corresponding position of the lower shell, the convex block extends into the clamping grooves to form clamping connection fixation of the upper shell and the lower shell, and through holes communicated with the clamping grooves are preset in the positions, corresponding to the clamping grooves, of the top of the upper shell.

Mutual joint is sealed between epitheca and the inferior valve, whole casing does not leave vent and other openings, because router itself calorific capacity is lower, under the prerequisite that does not set up the vent, the condition that inside temperature accumulation heaied up to the degree that the image router normally worked can not appear takes place, sealed design makes when placing the router on ground or easily receiving the tide place, router inside can maximize keeps dry, the corruption of humidity to inner wall electron device has been avoided, cause the condition that router life reduces by a wide margin to take place.

As a further scheme of the invention: the lug is the trapezium structure setting with the draw-in groove, when carrying out the casing and unpack apart with the joint, can be convenient unpack apart with the joint, avoid causing the destruction to drop to the lug.

As a further scheme of the invention: the upper shell is made of thin steel, the lower shell is made of plastic, the heat conductivity of the steel is larger than that of the plastic, and the thin steel increases the heat exchange rate between the interior and the exterior space of the router, so that the heat dissipation control of the interior temperature of the router is effectively carried out.

The quick cooling forming die of the router shell comprises a module consisting of a left die and a right die, wherein a main hydraulic rod is fixed at the middle positions of the upper back surfaces of the left die and the right die respectively, positioning rods are fixed on the upper back surfaces of the left die and the right die respectively near four corners, ball motors are fixed on the left die and the right die outside the main hydraulic rod respectively, a lead screw is connected to each ball motor in a transmission manner, extends to the left die and the right die and is close to one side, and a clamping block is welded at the end part of the lead screw, close to one side, of the left die and the right die.

Left side mould and right mould are close to the appearance that makes up into the casing under main hydraulic stem promotes down when moulding plastics, then start the injection molding machine mould plastics can, it directly waters the cooling water from the module after the completion to mould plastics, carry out rapid cooling and make the casing tentatively stereotype, main hydraulic stem work separates left side mould and right mould after tentatively stereotypeing the completion, ball motor work keeps lead screw rigidity, it supports to the casing formation to make lead screw and clamp splice, it can to water the cooling water on the casing once more, the design and the final shaping cooling required time of casing are shorter after moulding plastics, production efficiency has effectively been promoted.

As a further scheme of the invention: the clamp splice is located the interval intracavity that the corresponding position was predetermine on left mould and the right mould, and the ring channel has been predetermine to the clamp splice periphery near tip position, has placed sealed steel ring group in the ring channel, and sealed steel ring group supports to the spring looks butt of placing in interval chamber offside one end and the ring channel with one end, realizes sealedly, avoids plastics to flow into the interval intracavity.

As a further scheme of the invention: the electric heating piece is arranged on the second fixing frame corresponding to the right mold in a sticking mode and heats the edge position of the top opening of the lower shell, so that the flash of the left mold and the right mold in the sticking mode is softened, and the attractiveness is prevented from being influenced.

As a further scheme of the invention: and the outer sides of the front side, the rear side, the left side, the right side and the left side of the left die and the right die are respectively fixed with a second fixing frame and a first fixing frame through bolts, and the positioning rods are fixed with secondary hydraulic rods through fixing frames, and the secondary hydraulic rods are respectively and fixedly connected with the corresponding first fixing frame and the second fixing frame.
