Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. The components of the embodiments of the present application described and indicated in the drawings can be arranged and designed in various different configurations.

Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of the present application.

[0018] The injection moulding moulding blank for vertical air conditioner shell processing disclosed by the utility model is mainly applied to the scene that the injection moulding moulding blank for vertical air conditioner shell processing in the prior art cannot ensure that all parts are subjected to consistent force during ejection after injection moulding, thereby easily causing quality problems such as product inclination and deformation, and affecting the qualified rate and production efficiency of the product.

[0019] Reference Figure 1 And Figure 2 A kind of injection moulding moulding blank for vertical air conditioner shell processing, including top sealing plate 1, the bottom outer wall of top sealing plate 1 is equipped with casting plate 2, the bottom of casting plate 2 is equipped with upper mould plate 3, the bottom outer wall of upper mould plate 3 is attached with lower mould plate 4, lower mould plate 4 is internally provided with lower mould core, the bottom outer wall of lower mould plate 4 is equipped with support plate 5, the bottom outer wall of support plate 5 is equipped with bottom sealing plate 6, and further include: ejecting mechanism: the ejecting mechanism includes the multiple bottom needle plate 13 of bottom sealing plate 6 top outer wall, the top outer wall of multiple bottom needle plate 13 is correspondingly equipped with face needle plate 14, the top outer wall of multiple face needle plate 14 is equipped with long ejector pin 8, and the top outer wall of face needle plate 14 is equipped with short ejector pin 9;Injection mechanism: injection mechanism is set in the inside of casting plate 2.

[0020] The bottom sealing plate 6 provides a stable mounting platform for the ejection mechanism thereon. The plurality of bottom needle plates 13 are symmetrically distributed on the top outer wall of the bottom sealing plate 6, thereby ensuring uniform transmission of the ejection power. The long ejector pins 8 and the short ejector pins 9 are combined to apply uniform force to the product with different heights or depths, such as the edge and the middle part of the air conditioner shell, thereby preventing the product from tilting or deforming.

[0021] The plurality of bottom needle plates 13 are symmetrically distributed on the top outer wall of the bottom sealing plate 6, thereby enabling the ejection force to be uniformly distributed on each part of the product.

[0022] In particular, the long ejector pins 8 and the short ejector pins 9 are made of high-speed steel, which can make the surface roughness of the film blank reach a very low level, thereby reducing the marks generated when the ejector pins contact the product.

[0023] Referring to Figure 1 , Figure 3 and Figure 4 , in a preferred embodiment, the injection mechanism includes an injection pipe 12 arranged inside the casting plate 2. The upper die plate 3 is internally provided with a plurality of liquid outlets 11 on the side close to the casting plate 2. The upper die plate 3 is internally provided with an upper die core 10.

[0024] The molten plastic flows in the injection pipe 12. The balanced runner layout is adopted, thereby uniformly distributing the plastic to each liquid outlet 11, effectively avoiding the flow rate difference of the plastic during the flow process. The amount of plastic flowing out of each liquid outlet 11 is consistent, thereby uniformly filling the mold cavity with plastic and greatly improving the forming quality of the product and reducing product defects caused by uneven filling.

[0025] The injection pipe 12 is internally arranged in the casting plate 2 in a balanced runner layout. The balanced runner layout is adopted for the injection pipe 12, thereby uniformly distributing the plastic melt to each cavity and avoiding flow imbalance.

[0026] In particular, the top of the top sealing plate 1 is provided with a pouring port 15. The pouring port 15 gradually widens along the feeding direction and is distributed in a fan shape, thereby more uniformly dispersing the melt when it enters the cavity, reducing the flow speed of the melt, reducing the jet and vortex phenomenon, helping to improve the surface quality of the mold blank, and avoiding defects such as flow marks and bubbles.

[0027] Referring to Figure 1 and Figure 2 , in a preferred embodiment, the upper die plate 3 is internally provided with an upper die core 10. The two outer walls of the upper die plate 3 are respectively provided with two symmetrically distributed guide columns 7.

[0028] The guide pillar 7 provides accurate guidance for the movement of the upper mold plate 3.

[0029] Working principle: when in use, first, the plastic heated and melted into liquid state in the injection molding machine enters the mold base through the pouring port 15, wherein the pouring port 15 gradually widens along the feeding direction and is distributed in a fan shape, so that the molten material is more evenly dispersed when entering the cavity, reducing the flow speed of the molten material, reducing the jet and vortex phenomenon, which helps to improve the surface quality of the mold base. At this time, the molten plastic in the injection pipe 12 inside the pouring plate 2 is evenly discharged from the multiple liquid outlets 11 in the upper mold plate 3 due to the balanced runner layout of the injection pipe 12, at this time, the amount of plastic flowing out through each liquid outlet 11 is consistent, so that the plastic uniformly fills the mold cavity composed of the upper mold core 10 inside the upper mold plate 3 and the lower mold core inside the lower mold plate 4, reducing product defects caused by uneven filling. When the plastic gradually cools and solidifies in the cavity, the shape of the vertical air conditioner shell is formed, at this time, the guide provided by the guide pillar 7 for the opening movement of the upper mold plate 3 ensures that the upper mold plate 3 and the lower mold plate 4 are accurately separated. When it is necessary to eject the molded air conditioner shell from the mold, the face needle plate 14 is driven to move by the bottom needle plate 13, so that the long ejector pin 8 and the short ejector pin 9 eject the molded air conditioner shell from the mold. At this time, by using the combination of long ejector pin 8 and short ejector pin 9, the product is evenly stressed when being ejected, preventing the product from tilting or deforming.

[0030] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. The replacement can be a partial structure, device, method step replacement, or a complete technical solution. According to the technical solution and the utility model concept of the present application, equivalent replacement or change should be covered within the protection scope of the present application.
