Description

Technical Field

[0001] This application relates to the field of molds, and more particularly to a mold for injection molding a washing machine bottom filter screen with a mesh fabric. Background Technology

[0002] Molds are various molds and tools used in industrial production to obtain desired products through methods such as injection molding, blow molding, extrusion, die casting, forging, smelting, and stamping.

[0003] The washing machine filter (also known as a lint filter) is the core filtration component inside the washing machine. It is mainly used to intercept impurities such as fibers, hair, and lint that fall off clothes during the washing process, ensuring washing effect and preventing drainage system blockage.

[0004] See Figure 1 The washing machine filter 1 includes a fixing plate 11 and a filter part 12. After the existing mold forms the fixing plate 11, additional equipment or manual labor is required to connect and install the filter part 12 and the fixing plate 11. This results in low production efficiency and inconvenience, and needs to be improved. Utility Model Content

[0005] To improve the production efficiency of washing machine filters, this application provides a mold for injection molding a washing machine bottom filter with a mesh fabric.

[0006] This application provides a washing machine bottom filter mold with mesh fabric injection molding, which adopts the following technical solution:

[0007] A washing machine bottom filter mold with mesh fabric injection molding includes an upper mold and a lower mold. The lower mold is provided with a first forming groove, which is located on the side of the lower mold close to the upper mold. The upper mold is provided with a second forming groove, which is located on the side of the upper mold close to the lower mold. The first forming groove and the second forming groove form a forming cavity, which is used to fix the plate forming.

[0008] By adopting the above technical solution, the fixing plate and the filter screen are integrally formed, which improves the stability of the structure. Moreover, the automatic molding process improves production efficiency compared to manual assembly or additional machine assembly.

[0009] Optionally, the upper mold is provided with a fixing member, which is located on the side of the upper mold closer to the lower mold, and the fixing member restricts the positional displacement of the filter part.

[0010] By adopting the above technical solution and setting a fixing component, the filter screen part is limited and fixed by the fixing component, reducing the positional displacement of the filter screen part and making the mold forming more stable.

[0011] Optionally, the upper mold is provided with a fixing groove, and the fixing member includes a fixing pin, which extends out of the fixing groove and abuts against the filter screen.

[0012] By adopting the above technical solution, a fixing pin is set to press against the filter screen part to limit and fix the filter screen part, thereby reducing the positional displacement of the filter screen part.

[0013] Optionally, the lower mold is provided with a guide rod, which is located on the side of the lower mold closer to the upper mold, and the upper mold is provided with a guide groove for the guide rod to be inserted.

[0014] By adopting the above technical solution and setting guide rods, the upper mold moves towards the lower mold, making the forming of the fixed plate more stable.

[0015] Optionally, the guide rod has a tapered surface, which is located on the side of the guide rod closer to the upper mold, and the tapered surface is tapered in the direction closer to the upper mold.

[0016] By adopting the above technical solution, a tapered surface is set, which is located on the side of the guide rod near the upper mold. This facilitates the guide rod to be embedded in the guide groove during mold debugging, thereby improving the convenience of debugging.

[0017] In summary, this application includes at least one of the following beneficial technical effects:

[0018] 1. By setting up molding groove one and molding groove two, the fixing plate and the filter screen are integrally formed, which improves the stability of the structure. Moreover, the automatic forming by the mold improves the production efficiency compared with manual assembly or additional machine assembly.

[0019] 2. A fixing pin is provided. The fixing pin is used to press against the filter screen to limit and fix the filter screen, thereby reducing the positional displacement of the filter screen.

[0020] 3. A tapered surface is provided, located on the side of the guide rod near the upper mold. This facilitates the guide rod's insertion into the guide groove during mold adjustment, thus improving the ease of adjustment. Attached Figure Description

[0026] The present application will be further described in detail below with reference to the accompanying drawings.

[0027] This application discloses a mold for injection molding a washing machine bottom filter screen with a mesh fabric. (Refer to...) Figures 2 to 4 The system includes an upper mold 2 and a lower mold 3. The lower mold 3 has a first forming groove 10 located on the side of the lower mold 3 closest to the upper mold 2. The upper mold 2 has a second forming groove 13 located on the side of the upper mold 2 closest to the lower mold 3. The first forming groove 10 and the second forming groove 13 form a forming cavity 4, which is used to fix the plate 11 during forming. During forming, the filter screen 12 is located inside the forming cavity 4. When the internal temperature of the upper mold 2 rises, the filter screen 12 maintains its straightness due to the temperature and does not wrinkle.

[0028] The lower mold 3 is equipped with guide rods 5, which are located on the side of the lower mold 3 closest to the upper mold 2. The guide rods 5 have tapered surfaces 6, which are also located on the side of the guide rods 5 closest to the upper mold 2 and taper in the direction closest to the upper mold 2. The upper mold 2 is equipped with guide grooves 14 for the guide rods 5 to be inserted. In actual use, four guide rods 5 are provided, distributed along the four vertices of a rectangle.

[0029] The upper mold 2 is provided with a fixing member 7, which is located on the side of the upper mold 2 near the lower mold 3. The fixing member 7 restricts the positional displacement of the filter part 12. The upper mold 2 is provided with a fixing groove 9 for the fixing member 7 to be installed. In this application, the fixing member 7 is a fixing pin 8, which extends out of the fixing groove 9 and abuts against the filter part 12.

[0030] The implementation principle of the washing machine bottom filter mold with mesh fabric injection molding in this application embodiment is as follows: In actual use, this application directly connects the fixed plate 11 with the filter part 12 inside the mold during molding, thereby improving the stability of the connection and improving the processing efficiency.
