Description

Technical Field

[0001] The utility model belongs to the technical field of injection molds, and specifically relates to a travel charger mold structure. Background Art

[0002] Injection molds are important process equipment for producing various industrial products. With the rapid development of the plastic industry and the popularization and application of plastic products in industrial sectors such as aviation, aerospace, electronics, machinery, ships, and automobiles, injection molds are widely used in various industries. Injection molding is a processing method used in mass production of some complex-shaped parts, including mold closing, injection, pressure holding, cooling, demolding, and product removal. Specifically, it means injecting the heat-melted material into the mold cavity, and after cooling and solidifying, opening the mold to take out the formed product.

[0003] In the production of material injection molding, since the mold cavity needs to maintain high pressure during the shaping process, the upper and lower molds are pressed tightly under the action of high pressure, resulting in difficult separation of the upper and lower molds. Moreover, some of the formed material may adhere to the inner wall of the mold cavity, making it difficult to quickly demold. Therefore, we propose a travel charger mold structure. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a travel charger mold structure that can overcome or at least partially solve the above problems.

[0005] To solve the above technical problems, the basic concept of the technical solution adopted by the utility model is: a travel charger mold structure, including an upper mold and a lower mold, further including: cooling components are arranged in both the upper mold and the lower mold for cooling the upper mold and the lower mold; mold cavities are symmetrically opened in the upper mold and the lower mold, and a demolding component is arranged on the lower mold for demolding the model in the mold cavity.

[0006] Preferably, the cooling component includes: a main cooling water channel and a branch cooling water channel opened inside the upper mold, a main cooling water pipe and a branch cooling water pipe arranged in symmetrically opened grooves on the lower mold, the branch cooling water pipe is fixedly connected to the main cooling water pipe, the branch cooling water pipe corresponds to the branch cooling water channel, and a top piece is fixedly connected to the end of the branch cooling water pipe.

[0007] Furthermore, a first sliding groove is symmetrically opened in the groove, a tenon is fixedly connected to the outer wall of the main cooling water pipe, and the tenon is slidably connected in the first sliding groove.

[0008] Furthermore, a second sliding groove is also opened in the groove, and the second sliding groove penetrates through the lower mold.

[0009] Preferably, the demoulding assembly includes: a connecting rod, a slider, and a demoulding block. One end of the connecting rod is fixedly connected to the main cooling water pipe. The connecting rod is slidably connected in the second chute. A slider is fixedly connected to the connecting rod. The slider is slidably connected to the second chute. A demoulding block is fixedly connected to the upper part of the slider. An embedding groove corresponding to the demoulding block is formed in the cavity of the lower mould. The demoulding block is slidably connected in the embedding groove.

[0010] Preferably, a drain port is fixedly connected to the upper mould. The drain port corresponds to the main cooling water channel.

[0011] Preferably, positioning columns are fixedly connected to the lower mould, and positioning holes are formed in the upper mould. The positioning columns correspond to the positioning holes.

[0012] Preferably, injection ports are symmetrically formed in the upper mould and the lower mould.

[0013] After adopting the above technical solutions, the present utility model has the following beneficial effects compared with the prior art: By designing a cooling assembly with a demoulding function, the separation of the upper mould and the lower mould is realized through the movement of the cooling assembly, solving the problem that the upper mould and the lower mould are pressed tightly under high pressure and are difficult to open without tools. During the process of the cooling assembly separating the upper mould and the lower mould, the cooling assembly can also drive the demoulding block to eject the formed part from the cavity to complete demoulding, greatly improving the demoulding efficiency of the part. After the production is completed, the upper mould and the lower mould can be conveniently disassembled and cleaned, avoiding the decline of the mould precision caused by the residual part of the material in the cavity and improving the service life of the mould.

The following embodiments are used to illustrate the present utility model but are not intended to limit the scope of the present utility model.

[0022] Embodiment: Refer to Figures 1-4 , a travel charger mold structure, including an upper mold 1 and a lower mold 2, further including: cooling components are arranged in both the upper mold 1 and the lower mold 2 for cooling the upper mold 1 and the lower mold 2; mold cavities 25 are symmetrically opened in the upper mold 1 and the lower mold 2, and a demolding component is arranged on the lower mold 2 for demolding the parts formed in the mold cavity 25; the cooling components include: a main cooling water channel 32 and a cooling water branch channel 33 opened inside the upper mold 1, a main cooling water pipe 3 and cooling water branch pipes 31 arranged in the symmetrically opened grooves 22 on the lower mold 2, the cooling water branch pipes 31 are fixedly connected to the main cooling water pipe 3, the cooling water branch pipes 31 correspond to the cooling water branch channels 33, the ends of the cooling water branch pipes 31 are fixedly connected with top pieces 34; first chutes 23 are symmetrically opened in the grooves 22, tenons 35 are fixedly connected to the outer wall of the main cooling water pipe 3, and the tenons 35 are slidably connected in the first chutes 23; a second chute 24 is also opened in the grooves 22, and the second chute 24 penetrates through the lower mold 2; the demolding component includes: a connecting rod 4, a slide block 41, and a demolding block 42, one end of the connecting rod 4 is fixedly connected to the main cooling water pipe 3, the connecting rod 4 is slidably connected in the second chute 24, a slide block 41 is fixedly connected to the connecting rod 4, the slide block 41 is slidably connected to the second chute 24, a demolding block 42 is fixedly connected to the upper part of the slide block 41, an embedding groove corresponding to the demolding block 42 is opened on the mold cavity 25 of the lower mold 2, and the demolding block 42 is slidably connected in the embedding groove; a drainage port 12 is fixedly connected to the upper mold 1, and the drainage port 12 corresponds to the main cooling water channel 32; positioning posts 21 are fixedly connected to the lower mold 2, positioning holes 11 are opened on the upper mold 1, and the positioning posts 21 correspond to the positioning holes 11; injection ports 26 are symmetrically opened on the upper mold 1 and the lower mold 2;

[0023] The positioning holes 11 opened on the upper mold 1 are aligned with the positioning columns 21 fixedly connected to the lower mold 2 to install the upper mold 1 on the lower mold 2, and the lower part of the upper mold 1 is fitted with the upper part of the lower mold 2. At this time, the mold cavities 25 symmetrically opened on the upper mold 1 and the lower mold 2 form a complete cavity, and the cooling water branch pipe 31 and the corresponding cooling water branch channel 33 form a complete cooling assembly. The melted material is injected into the mold cavity 25 through the injection port 26, and cooling water is introduced through the cooling water main pipe 3. The cooling water enters the cooling water branch pipe 31 from the cooling water main pipe 3, and then enters the cooling water branch channel 33, and is finally discharged from the drain port 12 corresponding to the cooling water main channel 32, so as to cool the upper mold 1 and the lower mold 2 at the same time.

After the production is completed, the upper mold 1 and the lower mold 2 can be easily disassembled for cleaning to avoid the precision of the mold being reduced due to the residual material in the mold cavity 25, thereby improving the service life of the mold.

[0024] The utility model designs a cooling component with a demolding function, and realizes the separation of the upper mold 1 and the lower mold 2 through the movement of the cooling component, thereby solving the problem that the upper mold 1 and the lower mold 2 are tightly pressed under high pressure and are difficult to open without the aid of tools. In the process of separating the upper mold 1 and the lower mold 2 by the cooling component, the cooling component can also drive the demolding module 42 to eject the formed parts from the mold cavity 25 to complete the demolding, thereby greatly improving the efficiency of part demolding. After production is completed, the upper mold 1 and the lower mold 2 can be conveniently disassembled and cleaned, thereby avoiding the reduction of the mold precision caused by some residual materials in the mold cavity 25, thereby improving the service life of the mold.
