Description

Technical Field

[0001] This utility model relates to the field of air conditioner outdoor unit molding mold technology, specifically an air conditioner outdoor unit molding mold that facilitates mold core replacement. Background Technology

[0002] Air conditioners are an indispensable household appliance in modern families. They can provide a cool environment in the hot summer and bring warmth in the cold winter. The injection mold of the outdoor unit of the air conditioner is the core equipment for manufacturing the shell. Its design must take into account structural strength, heat dissipation efficiency and mass production stability.

[0003] Injection molding is a common plastic molding method. It involves injecting molten plastic material into a mold, which then cools and solidifies to obtain a product with a specific shape. The mold consists of components such as an upper fixed plate, a female mold plate, a female mold core, a lower fixed plate, a male mold plate, and a male mold core. The female and male mold cores fit together to form a molding cavity. During injection molding, the mold is clamped on the injection molding machine, and the 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 by the ejection system. Finally, the mold closes again for the next injection molding cycle. The entire injection molding process is cyclical.

[0004] The original mold can only be used for the production of a fixed type of air conditioner outdoor unit. When it comes to producing different air conditioner outdoor units, it is necessary to redesign a new mold to meet the production needs of that specific unit. This is not only costly but also wastes a lot of manpower and time on mold replacement.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] An air conditioner outdoor unit molding die that facilitates core replacement, such as Figure 1-7The device includes a lower fixed plate 6, with a male template 5 fixed on its upper surface. A female template 2, which is adapted to the male template 5, is vertically raised and lowered directly above the male template 5. An upper fixed plate 1 is fixed on the upper surface of the female template 2. Mold grooves 7 are provided on the upper surface of the male template 5 and the lower surface of the female template 2. A male mold core 4 is provided in the mold groove 7 of the male template 5, and a female mold core 3 is provided in the mold groove 7 of the female template 2. The male mold core 4 and the female mold core 3 cooperate to form the molding cavity of the air conditioner outdoor unit. During injection molding, the entire device is clamped on the injection molding machine. Molten plastic is injected into the molding cavity and cooled and solidified in the molding cavity. Then, the male template 5 and the female template 2 separate, and the product is ejected from the molding cavity and removed from the male mold core 4 and the female mold core 3 by the ejection system. This is existing equipment, so it will not be described in detail here.

[0030] like Figure 1 and Figure 2 and Figure 3 The male mold plate 5 is opened through the top and left side of the mold groove 7, and the female mold plate 2 is opened through the bottom and left side of the mold groove 7. In order to facilitate the replacement of the male mold core 4 and the female mold core 3 for injection molding different models of air conditioner outdoor units, the male mold plate 5 and the male mold core 4 are detachably fixedly connected by the first connecting component 8, and the female mold plate 2 and the female mold core 3 are detachably fixedly connected by the second connecting component 9, which improves the disassembly and assembly efficiency of the male mold core 4 and the female mold core 3, and does not require redesigning a new mold.

[0031] like Figure 1 and Figure 2 and Figure 3 The first connecting component 8 includes a movable plate 801 disposed within the mold groove 7 and adapted to the male mold core 5 and the mold groove 7. The male mold core 4 is fixed on the movable plate 801. A handle 802 for controlling the movement of the movable plate 801 is fixed to the left end of the movable plate 801. By grasping the handle 802 and manually moving the handle 802, the movable plate 801 and the male mold core 4, which are integrated with the handle 802, can be driven, making it convenient to pull out and disassemble the male mold core 4 without requiring the operator to forcefully tilt the male mold core 4 out. The movable plate 801 has strip-shaped sliding grooves 803 on both the front and rear sides, and strip-shaped grooves adapted to it are slidably connected in the strip-shaped sliding grooves 803. The slider 804 extends into a strip groove 803. The portion of the slider 804 extending into the strip groove 803 is fixed to the wall of the mold groove 7. By setting the mutually cooperating strip groove 803 and slider 804, the movement of the movable plate 801 is limited and guided. This facilitates the movement of the movable plate 801 while restricting its position, without affecting the injection molding of the male mold core 4. The length of the movable plate 801 is greater than the length of the male mold core 4. When the mold is closed, the female mold core 3 is nested outside the male mold core 4 and abuts against the movable plate 801, reducing the possibility of flash and overflow during injection molding.

[0032] like Figure 1 and Figure 2 and Figure 3When assembling the male mold core 4, grasp the handle 802 and push the moving plate 801 and the male mold core 4 to move in the mold groove 7 until they abut against the right end wall of the mold groove 7. At this time, in order to improve the stability of the moving plate 801 and the male mold core 4, the male mold plate 5 is provided with a limiting component to limit and fix the male mold core 4 entering the mold groove 7, so that the male mold core 4 is fixed in a suitable position to facilitate the normal injection molding process.

[0033] like Figure 4 and Figure 5 and Figure 6 and Figure 7 The limiting component includes a first cylindrical hole 805, a second cylindrical hole 810, and a third cylindrical hole 811 located at the left ends of the front and rear sides of the upper surface of the template 5. The second cylindrical hole 810 is located directly below the first cylindrical hole 805 and is coaxially arranged with the first cylindrical hole 805. The third cylindrical hole 811 is located between the first cylindrical hole 805 and the second cylindrical hole 810 and is arranged perpendicular to the first cylindrical hole 805. The first cylindrical hole 805, the second cylindrical hole 810, and the third cylindrical hole 811 are interconnected.

[0034] like Figure 4 and Figure 5 and Figure 6 and Figure 7 A support ring 806 is fixed to the inner wall of the first cylindrical hole 805. A nut 807 is coaxially mounted on the support ring 806 and rotatably connected to it. A screw 808 adapted to the nut 807 passes through the nut 807 and the support ring 806. One end of the screw 808 that passes through the nut 807 and the support ring 806 is coaxially fixed to a connecting post 809 adapted to the second cylindrical hole 810. The connecting post 809 enters the second cylindrical hole 810 and is slidably connected to the second cylindrical hole 810 via a slide rail. A slot 812 is formed on the outer circumference of the connecting post 809. It consists of a first vertical surface 812-1 and a first inclined surface 812-2. A clamping rod 813, which is adapted to and slidably connected to the third cylindrical hole 811, is slidably connected inside the third cylindrical hole 811. A insertion hole 814, which is adapted to the connecting post 809, passes through the middle of the clamping rod 813. One side of the insertion hole 814 is a second vertical surface 814-1 adapted to the first inclined surface 812-2. The upper and lower sides of the second vertical surface 814-1 of the insertion hole 814 are provided with second inclined surfaces 814-2 adapted to the first inclined surface 812-2 to facilitate the movement of the clamping rod 813.

[0035] like Figure 4 and Figure 5 and Figure 6 and Figure 7A sleeve 815 is fixed to the inner wall of the third cylindrical hole 811. A slide rod 816 is slidably connected inside the sleeve 815. One end of the slide rod 816 extends out of the sleeve 815. The end of the slide rod 816 extending out of the sleeve 815 is fixed to the end of the clamping rod 813. The clamping rod 813 and the sleeve 815 are fixedly connected by a spring 817 sleeved on the outside of the slide rod 816.

[0036] like Figure 4 and Figure 5 and Figure 6 and Figure 7 The lower surface of the female template 2 is provided with a groove that is compatible with the screw 808, so as not to affect the contact between the bottom end of the female template 2 and the top end of the male template 5 during injection molding. The clamping rod 813 is provided with a connecting groove 818 that is compatible with the moving plate 801 on the side facing the moving plate 801. When the end of the groove wall of the connecting groove 818 contacts the moving plate 801, the clamping rod 813 moves to a suitable position. The first connecting component 8 and the second connecting component 9 have the same structure.

[0037] When in use, connect the power supply and turn on the switch. When it is necessary to disassemble and replace the male mold core 4 and the female mold core 3, after the male mold core 4 and the female mold core 3 are separated, the worker grasps the nut 807 and manually rotates the nut 807. The rotation of the nut 807 causes the screw 808, which is threadedly connected to the nut 807, to move down in the first cylindrical hole 805, which in turn causes the connecting post 809, which is coaxially fixed to the screw 808, to move down in the second cylindrical hole 810. Through the cooperation of the slot 812 and the insertion hole 814, the spring 817 rebounds, causing the slide rod 816 and the clamping rod 813, which are fixedly connected to the spring 817, to move towards the sleeve 815. When the clamping rod 813 is retracted into the third cylindrical hole 811, the worker grasps the handle 802 and pulls out the moving plate 801, which is fixedly connected to the handle 802, and then replaces the appropriate female mold core 3 and male mold core 4. It is not necessary to forcefully tilt the female mold core 3 and the male mold core 4.

[0038] After replacing the suitable female mold core 3 and male mold core 4, the worker grasps the handle 802 and pushes the moving plate 801 into the mold groove 7. The movement of the moving plate 801 is limited and guided by the strip groove 803 and strip slider 804 until the moving plate 801 moves to the right end of the mold groove 7 and touches the groove wall. Then, the worker grasps the nut 807 and manually rotates it in the opposite direction, causing the screw 808 to move upwards within the first cylindrical hole 805. The first vertical surface 812-1, the first inclined surface 812-2, and the second vertical surface 814-1 cooperate, and the clamping rod 813 moves horizontally away from the sleeve 815. The spring 817 is stretched, and the clamping rod 813 moves and abuts against the left side wall of the moving plate 801 until the groove wall with an L-shaped cross section abuts against the front or rear side wall of the moving plate 801. At this time, the clamping rod 813 cooperates with the mold groove 7 to clamp the moving plate 801, and the moving plate 801 is located in a suitable position.

[0039] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
