In view of Above defective, it is necessary to design a kind of mobile phone back cover mould.

Utility model content

The technical problem to be solved by the utility model is to provide a mold for the back cover of a mobile phone to solve the problem that the current aluminum alloy needs to be manually drained after being formed by die-casting.

In order to solve the above-mentioned technical problems, the technical solution of the utility model is: a mobile phone back cover mold, including an upper mold base and a lower mold base, a first cavity mold is arranged in the upper mold base, and A feed pipe is provided, and the feed pipe runs through the first cavity mold, a second cavity mold is provided in the lower mold base, a sealing groove and a clamping groove are provided in the first cavity mold, and the clamping groove It communicates with the sealing groove, and a sealing pushing block is arranged in the locking groove, and one end of the sealing pushing block is connected with a pushing mechanism, and the pushing mechanism pushes the sealing pushing block to slide along the locking groove.

Further, the pushing mechanism is a hydraulic pushing mechanism or a cylinder pushing mechanism.

Further, a guide sleeve is provided on the upper die base, and a guide post is provided on the lower die base, and the guide post penetrates through the guide sleeve.

Further, the upper mold base is also provided with a first cooling water tank, a first water inlet hole and a first water outlet hole, and the first water inlet hole and the first water outlet hole communicate with the first cooling water tank; The lower mold base is also provided with a second cooling water tank, a second water inlet hole and a second water outlet hole, and the second water inlet hole and the second water outlet hole communicate with the second cooling water tank.

Compared with the prior art, the mobile phone back cover mould, through the clamping of the upper mold base and the lower mold base, makes the first cavity mold and the second cavity mold form a sealed space, and the molten aluminum alloy passes through the material hole Inject into the first cavity mold and the second cavity mold, and then push the sealing push block to slide in the card groove by the pushing mechanism, so that the sealing push block engages with the sealing groove, so that the sealing push block is opposite to the first cavity mold It plays a sealing role, and at the same time isolates the material tube and the first cavity mold, so as to cut off the nozzle in a liquid state, so the formed product has no nozzle, and avoids the need to manually remove the nozzle after the part is demolded, not only Reduce the workload and ensure the surface quality of the product.

Description of drawings

Fig. 2 is a cross-sectional view of the upper mold base of the mobile phone back cover mould.

The following specific embodiments will be further described in conjunction with the above-mentioned drawings.

detailed description

In the following, numerous specific details are set forth in order to provide a thorough understanding of the concepts underlying the described embodiments. It will be apparent, however, to one skilled in the art that the described embodiments may be practiced without some or all of these specific details. In other instances, well known processing steps have not been described in detail.

As shown in Figure 1-2, a mobile phone back cover mold includes an upper mold base 1 and a lower mold base 2, the upper mold base 1 is provided with a first cavity mold 3, and the upper mold base 1 is provided with There is a material pipe 4, the material pipe 4 runs through the first cavity mold 3, the second cavity mold 5 is arranged in the lower mold base 2, and the sealing groove 6 and the clamping groove 6 are arranged in the first cavity mold 3. Groove 7, the card groove 7 communicates with the sealing groove 6, the sealing push block 8 is arranged in the card groove 7, and a push mechanism 9 is connected to one end of the seal push block 8, and the push mechanism 9 pushes the seal The push block 8 slides along the slot 7 . The mobile phone back cover mould, through the upper mold base 1 and the lower mold base 2, makes the first cavity mold 3 and the second cavity mold 5 form a sealed space, and the molten aluminum alloy is injected into the second cavity mold through the material hole. In the first cavity mold 3 and the second cavity mold 5, the pushing mechanism 9 pushes the sealing push block 8 to slide in the slot 7, so that the sealing push block 8 engages with the sealing groove 6, so that the sealing push block 8 is The first cavity mold 3 acts as a seal, and at the same time isolates the material tube and the first cavity mold 3, so as to cut off the nozzle in a liquid state, so that the formed product does not have a nozzle, and prevents the part from being demolded Finally, the nozzle needs to be manually removed, which not only reduces the workload, but also ensures the surface quality of the product.

Further, the pushing mechanism 9 is a hydraulic pushing mechanism or a cylinder pushing mechanism.

Further, the upper mold base 1 is provided with a guide sleeve 101 , and the lower mold base 2 is provided with a guide post 201 , and the guide post 201 penetrates through the guide sleeve 101 . Therefore, when the mold is closed, the upper mold base 1 and the lower mold base 2 are guided by the guide post 201 and the guide sleeve 101 .

Further, the upper mold base 1 is also provided with a first cooling water tank 102, a first water inlet hole 103 and a first water outlet hole 104, and the first water inlet hole 103 and the first water outlet hole 104 are connected to the first water outlet hole 104. Cooling water tank 102 runs through; The second cooling water tank 202, the second water inlet hole 203 and the second water outlet hole 104 are also provided on the lower mold base 2, and the second water inlet hole 203 and the second water outlet hole 204 are connected with the second water outlet hole 204. The second cooling water tank 202 passes through. Therefore, the first water inlet 103 and the second water inlet 203 are connected to the water inlet pipe, and the first outlet hole 104 and the second water outlet 204 are connected to the water outlet pipe, so that the first cooling water tank 102 and the second cooling water tank 202 Add cold water in, reach and play cooling effect to the first cavity mold 3 and the second cavity mold 5.

The utility model is not limited to the above-mentioned specific implementation manners, and various transformations made by those skilled in the art starting from the above-mentioned ideas without creative work all fall within the protection scope of the utility model.
