Description

Technical Field

[0001] This application relates to the field of washing machine mold structures, and in particular to a washing machine tub mold structure with good smoothness. Background Technology

[0002] A washing machine is a cleaning appliance that uses electrical energy to generate mechanical action to wash clothes. With the improvement of living standards, washing machines have become one of the indispensable appliances in modern families.

[0003] The washing machine tub is injection molded, and the mold cavity is formed by several sliders. During demolding, the sliders and the product need to be separated. The mold is equipped with inclined guide pillars that extend away from the product. The sliders have guide holes for the inclined guide pillars to slide. During demolding, the sliders slide along the length of the inclined guide pillars, causing them to separate from each other, and the product is demolded circumferentially. However, the sliders are heavy, and the ejection force of the ejection mechanism is large. The sliders are supported by the inclined guide pillars. When the ejector pushes the slider to the end, the inclined guide pillars need to withstand a large force, which can easily cause the mold to seize up, or the inclined guide pillars to develop burrs, affecting the use of the mold. Summary of the Invention

[0004] In order to prevent the mold from getting stuck when the slider is ejected and to ensure smooth overall mold transport, this application provides a washing machine tub mold structure with good smoothness.

[0005] This application provides a washing machine tub mold structure with good flowability, employing the following technical solution:

[0006] A smooth-flowing washing machine tub mold structure includes a lower mold base and a slider slidably disposed on the lower mold base. Several mounting blocks are arranged around the lower mold base. The slider is located between two adjacent mounting blocks. When the slider slides to abut against the lower mold base, the sliders form a molding cavity. The sides of the slider are slidably connected to the mounting blocks. The sliding direction of the slider is an extension direction from the bottom to the top of the mounting block, and the extension direction is inclined away from the molding cavity. Furthermore, when the slider slides away from the lower mold base, the outer circumferential wall of the product is demolded.

[0007] By adopting the above technical solution, when the mold needs to be demolded after injection molding, both sides of the slider are slidably set in the inclined guide groove. The slider slides along the length of the inclined guide groove for demolding. The slider has a large support area and good load-bearing capacity when it slides. At the same time, the two mounting blocks make the slider stable when it slides, so that the mold is not easy to get stuck when the slider is ejected, and the overall mold is transported smoothly.

[0008] Optionally, the mounting block has an inclined guide groove on its side wall facing the slider. The length direction of the inclined guide groove is the same as the sliding direction of the slider. The slider includes a release module and guide blocks disposed on both sides of the release module. The guide blocks are slidably disposed in the inclined guide groove.

[0009] By adopting the above technical solution, the guide block is slidably set in the inclined guide groove, and the two sides of the detachment module are slidably connected to the side of the mounting block. The guide block and the detachment module increase the sliding contact area with the mounting block, thereby improving the sliding stability of the slider.

[0010] Optionally, the guide block can be detachably mounted on both sides of the detachable module.

[0011] By adopting the above technical solution, the guide block can be detached, which facilitates the replacement of the guide block after long-term use due to wear and tear. The guide block is easy to replace and there is no need to replace the entire slider.

[0012] Optionally, when the slider forms a mold cavity, the end of the guide block near the lower mold base protrudes into an inclined guide groove.

[0013] By adopting the above technical solution, when the slider is in the state of forming the mold cavity, the guide block still has a large part of abutting against the mounting block, and the guide block has a good support effect.

[0014] Optionally, guide posts are provided at all four corners of the lower mold base, and the mounting block is sleeved on the guide posts, which allow the upper mold base to slide.

[0015] By adopting the above technical solution, the guide post facilitates the installation and positioning of the mounting block, and the mounting block is fitted onto the guide post, thereby improving the stability of the mounting block.

[0016] Optionally, the lower mold base is provided with a plurality of ejector holes, which are evenly distributed at the bottom of the slider.

[0017] By adopting the above technical solution, the rod on the injection molding machine pushes the slider out through the ejection hole, which facilitates the demolding of the slider.

[0018] In summary, this application includes at least one of the following beneficial technical effects:

[0019] 1. When the mold needs to be demolded after injection molding, the slider is slidably set on both sides of the inclined guide groove. The slider has a large support area and good load-bearing capacity when it slides. The slider is stable when it slides. The mold is not easy to get stuck when the slider is ejected. The overall mold is transported smoothly.

[0020] 2. By using guide blocks and detachable modules to increase the sliding contact area with the mounting block, the sliding stability of the slider is improved;

[0021] 3. The guide block is detachable, making it easy to replace after long-term use due to wear and tear. Attached Figure Description

[0026] The following is in conjunction with the appendix Figure 1 -Appendix Figure 3 This application will be described in further detail.

[0027] This application discloses a washing machine tub mold structure with good flowability. (Refer to...) Figure 1 , Figure 2 , Figure 3 The washing machine tub mold structure with good smoothness includes a lower mold base 1 and a slider 2 slidably disposed on the lower mold base 1. Several mounting blocks 3 are fixed around the lower mold base 1, and the slider 2 is located between two adjacent mounting blocks 3. When the slider 2 slides to abut against the lower mold base 1, the sliders 2 form a forming cavity 4. Guide posts 7 are fixed on all four corners of the lower mold base 1, and the mounting blocks 3 are sleeved on the guide posts 7, which allow the upper mold base to slide. Several ejection holes 6 are opened on the lower mold base 1, and the ejection holes 6 are evenly distributed at the bottom of the slider 2.

[0028] Reference Figure 1 , Figure 2 , Figure 3 The slider 2 is slidably connected to the mounting block 3 on both sides. The sliding direction of the slider 2 is along the bottom to the top of the mounting block 3, and the extension direction is inclined away from the molding cavity 4. When the slider 2 slides away from the lower mold base 1, the outer wall of the product is demolded.

[0029] Reference Figure 1 , Figure 2 , Figure 3 The mounting block 3 has an inclined guide groove 5 on its side wall facing the slider 2, and the length direction of the inclined guide groove 5 is the same as the sliding direction of the slider 2. The slider 2 includes a release module 21 and guide blocks 22 disposed on both sides of the release module 21. The guide blocks 22 are detachably disposed on both sides of the release module 21. The guide blocks 22 are slidably connected to the inclined guide groove 5. When the slider 2 is in the mold cavity state, the end of the guide block 22 near the lower mold base 1 protrudes from the inclined guide groove 5.

[0030] The implementation principle of a washing machine tub mold structure with good smoothness in this application embodiment is as follows: When the mold needs to be demolded after injection molding, both sides of the guide block 22 are slidably connected to the inclined guide groove 5. The rod on the injection molding machine pushes out the slider 2 through the ejection hole. The guide block 22 slides along the length direction of the inclined guide groove 5 for demolding. When the slider 2 slides, the support area with the mounting block 3 is large and the load-bearing capacity is good. At the same time, the two mounting blocks 3 make the slider 2 stable when sliding, so that the mold is not easy to get stuck when the slider 2 is ejected, and the overall mold is transported smoothly.
