Technical Field
[0001] This utility model relates to the field of air conditioner housing injection molding technology, specifically to a mold adjustment device for air conditioner housing injection molding. Background Technology
[0002] In today's society, with the rapid development of science and technology and the continuous improvement of people's living standards, home appliances have become an indispensable part of our daily lives. Among them, air conditioners, as important equipment for regulating indoor temperature and improving living comfort, are increasingly attracting consumers' attention in terms of appearance design and performance quality. As an important component of air conditioning products, the air conditioner casing not only plays a role in protecting the internal structure, but is also the key to showcasing the product's aesthetics.
[0003] As a crucial component of air conditioners, the air conditioner casing requires a sophisticated injection molding process. Injection molding involves injecting molten plastic material into a mold, which then cools and solidifies to create a product with a specific shape. The mold consists of components such as an upper fixed plate, a moving mold, a lower fixed plate, and a stationary mold. The moving and stationary molds work together to form a molding cavity. During injection molding, the mold is clamped on an injection molding machine, and molten plastic is injected into the molding cavity, where it cools and solidifies. Then, the upper and lower molds separate, and the product is ejected from the mold cavity via an ejection system. Finally, the mold closes again for the next injection molding cycle. The entire injection molding process is cyclical, offering advantages such as high production efficiency, stable product quality, and the ability to mass-produce.
[0004] However, in existing air conditioner casing injection molds, the lower fixed plate and stationary mold are fixed on the injection molding machine, while the upper fixed plate and moving mold are raised and lowered directly above the lower fixed plate and stationary mold. The height of the lower fixed plate and stationary mold is fixed. During the low-pressure mold closing stage, if the height error of the stationary mold exceeds 0.1mm, it will cause impact damage to the mold, such as slider displacement or ejector pin breakage, affecting the quality of the injection molded product.

[0018] A mold adjustment device for injection molding an air conditioner casing, such as Figure 1-5 The mold body 1 consists of an upper fixed plate 101, a moving mold 102, a lower fixed plate 104, and a stationary mold 103. The mold body 1 is fixed on the injection molding machine. The upper fixed plate 101 and the moving mold 102 are fixedly connected, and the lower fixed plate 104 and the stationary mold 103 are fixedly connected. The upper fixed plate 101 and the moving mold 102 are raised and lowered and positioned directly above the lower fixed plate 104 and the stationary mold 103. This is prior art, so it will not be described in detail here.
[0019] like Figure 1 and Figure 2 and Figure 3 and Figure 4 The lower surface of the lower fixed plate 104 is provided with an upper support plate 2 and a lower support plate 3 from top to bottom. The upper support plate 2 and the lower fixed plate 104 are detachably fixedly connected by several evenly arranged support rods 4. The upper support plate 2 and the lower support plate 3 are connected by an adjustment component 5 for adjusting the height of the lower fixed plate 104. The adjustment component 5 provides power so that the integrated structure of the upper support plate 2, support rods 4, lower fixed plate 104 and stationary mold 103 can move in the vertical direction, so as to adjust the height of the stationary mold 103 and match the stroke of the mold clamping mechanism, thereby improving the quality of the injection molded product.
[0020] like Figure 1 and Figure 2 and Figure 3 and Figure 4 The adjusting component 5 includes several lugs 501 evenly fixed on the lower surface of the upper support plate 2. Each lug 501 is rotatably connected to a roller 502. Several connecting plates 503 are fixed on the lower support plate 3. Each connecting plate 503 has a push block 504 corresponding to a roller 502 fixed on the side opposite to the lower support plate 3. The upper surface of the push block 504 is an inclined surface adapted to the roller 502. A cylinder 505 is fixed on the injection molding machine to drive the lower support plate 3 to move horizontally. Power is provided by the cylinder 505 to drive the lower support plate 3, which is fixed to the extended end of the cylinder 505, to move horizontally. The movement of the lower support plate 3 will drive the connecting plate 503 and the push block 504, which are integrated with the lower support plate 3, to move. The movement of the push block 504 cooperates with the roller 502 to drive the upper support plate 2 to move vertically.
[0021] like Figure 1 and Figure 2 and Figure 3 and Figure 4 Several slide rails 506 are fixed on the injection molding machine along the moving direction of the lower support plate 3. Each slide rail 506 is slidably connected to a slider 507. The side of the slider 507 away from the slide rail 506 is fixed to the lower support plate 3. Through the cooperation of the slide rail 506 and the slider 507, the movement of the lower support plate 3 in the horizontal direction is guided and limited.
[0022] like Figure 1 and Figure 2 and Figure 3 and Figure 4 and Figure 5Vertical guide rods 6 are fixed at the four corners of the lower surface of the upper support plate 2. Guide sleeves 7 are slidably connected to the guide rods 6. The bottom end of the guide sleeves 7 is fixed to the injection molding machine. The injection molding machine also has a guide groove located directly below the guide sleeves 7 and communicating with the inner cavity of the guide sleeves 7. The guide rods 6 pass through the bottom end of the guide sleeves 7 and enter the guide groove and are slidably connected to the guide groove. Through the cooperation of the guide sleeves 7, the guide groove and the guide rods 6, the movement of the upper support plate 2 in the vertical direction is guided and limited.
[0023] like Figure 1 and Figure 2 and Figure 3 and Figure 4 and Figure 5 A balancing assembly 8 is provided on the sides of two adjacent guide sleeves 7 to balance the movement of the left and right guide rods 6. The balancing assembly 8 includes a strip-shaped hole on the outer circumference of the guide rod 6, and a rack 801 is fixed to the inner wall of the strip-shaped hole. An arc-shaped hole 802 communicating with the inner cavity of the guide sleeve 7 is provided on the outer wall of the guide sleeve 7. Several ear plates 803 are fixed on the injection molding machine. A drive shaft 804 rotatably connected to the ear plates 803 passes through the ear plates 803. A coaxial device is nested on the drive shaft 804. A fixed gear 805 extends into the inner cavity of the guide sleeve 7 through an arc-shaped hole 802. The part of the gear 805 extending into the inner cavity of the guide sleeve 7 meshes with the rack 801. When the upper support plate 2 moves in the vertical direction, it will drive the guide rod 6, which is integrated with the upper support plate 2, to move in the vertical direction. The rack 801 is fixed in the strip-shaped hole, which does not affect the sliding connection between the guide rod 6 and the guide sleeve 7. The movement of the rack 801 will drive the gear 805 meshing with the rack 801 to rotate, so as to achieve the balance effect of the guide rods 6 on both sides.
[0024] When in use, connect the power supply and turn on the switch. When it is necessary to adjust the height of the stationary mold 103 according to the stroke of the mold clamping mechanism, the operator opens the cylinder 505. The cylinder 505 provides power to drive the lower support plate 3, which is fixedly connected to the extended end of the cylinder 505, to move in the horizontal direction. Through the cooperation of the slide rail 506 and the slider 507, the movement of the lower support plate 3 in the horizontal direction is guided and limited. The movement of the lower support plate 3 will drive the connecting plate 503 and the push block 504, which are integrated with the lower support plate 3, to move. The movement of the push block 504 cooperates with the roller 502 to drive the upper support plate 2 to move in the vertical direction. The movement of the upper support plate 2 will drive the support rod 4, the lower fixed plate 104 and the stationary mold 103, which are integrated with the upper support plate 2, to move in the vertical direction. The push block 504 is provided with a sliding groove, and the roller 502 moves in the sliding groove to reduce the possibility of the roller 502 falling off the push block 504. Simultaneously, the movement of the lower support plate 3 will cause the guide rod 6, which is fixed to the lower support plate 3, to move within the guide sleeve 7 and the guide groove. The movement of the guide rod 6 will cause the rack 801, which is fixed to the guide rod 6, to move. The movement of the rack 801 will cause the gear 805 meshing with the rack 801 to rotate. The two gears 805 are coaxially fixed through the transmission shaft 804, realizing the synchronous movement of the left and right sides of the upper support plate 2 and improving the stability of the movement of the stationary mold 103.
