Abstract
Description
Technical Field
[0001] The invention relates to the technical field of air-conditioning accessories, in particular to an anti-deformation injection mould for an air-conditioning panel. Background Art
[0002] In modern manufacturing, air conditioning panels are an important part of air conditioning systems, and their quality and performance directly affect the overall use effect and user satisfaction of air conditioning. However, when manufacturing air conditioning panels, traditional injection molds often face problems such as low injection molding precision, low cooling efficiency, and difficulty in opening molds and removing parts. These problems not only affect the yield and quality of the products, but also increase production costs and operational difficulties.
[0003] First of all, injection molding accuracy is the key to manufacturing air conditioner panels. Traditional injection molds are not precisely controlled, which easily leads to deviations between the upper and lower molds during the mold closing process, thus affecting the uniform distribution and cooling and solidification of the raw materials in the mold cavity, and ultimately causing deformation or inaccurate dimensions of the air conditioner panel. This not only affects the aesthetics of the product, but may also affect its functionality and service life.
[0004] Secondly, cooling efficiency is another important factor affecting the production cycle and quality of air conditioner panels. Traditional cooling methods often use natural cooling or simple water cooling, which are slow and inefficient, resulting in longer production cycles and not conducive to the stability of product quality. In addition, due to uneven cooling, stress may also be generated inside the air conditioner panel, further affecting its performance.
[0005] Finally, the mold opening and part removal process is also a problem faced by traditional injection molds. Due to the complex mold structure, it is often difficult to quickly and safely remove the product after the mold is opened, which not only increases the difficulty of operation, but may also cause damage to the product. At the same time, if the mold temperature is too high, it may also pose a safety hazard to the operator. Summary of the invention
[0006] In view of the problems existing in the above-mentioned background technology, the present invention patent aims to propose an innovative solution, namely, an anti-deformation injection mold for air-conditioning panels.
[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions: an anti-deformation injection mold for air-conditioning panels, comprising a base, a servo motor, a cooling box, a cooling pipe and a fan blade group, the top of the base is fixedly connected to two fixed plates, a connecting plate is fixedly connected between the two fixed plates, the servo motor is fixedly connected to the top of the connecting plate, the driving end of the servo motor is fixedly connected to a screw rod, the outer surface of the screw rod is threadedly connected to an injection molding device, the bottom of the injection molding device is fixedly connected to an upper mold, the upper mold is located in front of the screw rod, the top of the base is fixedly connected to a lower mold, the lower mold is located between the two fixed plates, the upper mold is fitted with the lower mold, and the bottom of the connecting plate is fixedly connected to A fixing rod, wherein the fixing rod is connected through a placement plate, the cooling box is installed on the top of the placement plate, the cooling pipe is installed on the bottom of the cooling box, the cooling pipe is composed of a connecting pipe and an annular pipe, the annular pipe sleeve of the cooling pipe is arranged on the outer surfaces of the upper mold and the lower mold, a worm is arranged on one side of the lower mold, the two ends of the worm are respectively located at the base and the connecting plate for rotation connection, the top end of the screw rod and the top end of the worm are both fixedly connected through a transmission wheel, the outer surfaces of the two transmission wheels are sleeved with a transmission belt, one of the fixing plates is rotatably connected to a rotating rod near the side wall of the worm, the end of the rotating rod near the lower mold is fixedly connected to a worm wheel, the worm is meshingly connected to the worm wheel, and the fan blade group is installed on the outer surface of the rotating rod.
[0008] Preferably, a fixing block is fixedly connected to the bottom end of the fixing rod, and the fixing block is in contact with the bottom of the placement plate.
[0009] Preferably, a limiting rod is fixedly connected between the base and the connecting plate, the screw rod is located directly in front of the limiting rod, and the limiting rod passes through the injection molding equipment.
[0010] Preferably, the placement plate is located directly above the injection molding equipment.
[0011] Preferably, the central axis of the rotating rod is located on the contact surface of the upper mold and the lower mold, and the fan blade group is located on one side of the cooling pipe.
[0012] Working principle: When an anti-deformation injection mold for air conditioner panel is used, the servo motor drives the screw, and the screw drives the injection molding equipment to move. The limit rod limits the injection molding equipment to ensure that the screw can accurately drive the injection molding equipment to drive the upper mold to move up and down. After the upper mold and the lower mold are closed, the injection molding equipment injects the hot melt raw material (such as thermoplastic) into the upper mold. The raw material is cooled and solidified in the cavity of the upper mold and the lower mold to form an air conditioner panel. The connecting pipe on the cooling pipe guides the cooling water in the cooling box into the annular pipe of the cooling pipe. The annular pipe sleeve is set on the outer surface of the upper mold and the lower mold, and the cooling water circulates in the annular pipe to cool the mold. At the same time, the transmission wheel on the worm is connected to the transmission wheel on the screw through the transmission belt. When the screw rotates, the transmission belt drives the worm to rotate. The worm meshes with the worm wheel on the rotating rod, driving the worm wheel to drive the rotating rod to rotate. The fan blade group on the rotating rod rotates accordingly, so that the flowing air passes through the surface of the circulation pipe of the cooling pipe, further reducing the temperature of the cooling pipe and the mold. When the air conditioning panel is injection molded and fully cooled, the servo motor drives the injection molding equipment to move the upper mold upward to separate the upper mold from the lower mold. At this time, the annular tube of the cooling pipe is still sleeved on the outer surface of the lower mold to prevent the operator from contacting the hot air conditioning panel too early. As the screw continues to drive the injection molding equipment upward, the injection molding equipment contacts the placement plate and drives it upward. The placement plate drives the circulation tube of the cooling pipe to move upward and detach from the lower mold, so that the operator can easily remove the air conditioning panel in the lower mold.
[0013] The present invention provides an anti-deformation injection mold for air conditioner panels. It has the following beneficial effects: 1. Efficient and accurate injection molding: The servo motor drives the screw rod to achieve precise control of the injection molding equipment, ensuring that the upper and lower molds can be accurately closed, thereby ensuring the stability and accuracy of the injection molding process. The hot-melt raw materials (such as thermoplastics) are evenly distributed in the mold cavity and cooled and solidified, effectively avoiding the deformation of the air conditioner panel and improving the yield and quality of the product.
[0014] 2. Fast and effective cooling system: The annular tube sleeve on the cooling tube is set on the outer surface of the upper mold and the lower mold. The cooling water circulates in the annular tube, which can quickly take away the heat of the mold and accelerate the cooling process of the air conditioning panel. The transmission mechanism composed of the worm, transmission belt, worm wheel and rotating rod drives the fan blade group to rotate, so that the flowing air passes through the circulation tube surface of the cooling tube, further enhancing the cooling effect and shortening the production cycle.
[0015] 3. Safe and convenient mold opening and part removal: When the air conditioning panel is completed and fully cooled, the servo motor drives the injection molding equipment to move the upper mold upward to separate the upper mold from the lower mold. The operation process is simple and safe. The annular tube of the cooling pipe is still sleeved on the outer surface of the lower mold in the initial stage, which effectively prevents the operator from contacting the hot air conditioning panel too early and avoids safety hazards such as burns. As the screw continues to drive the injection molding equipment to move upward, the placement plate drives the circulation tube of the cooling pipe to move upward and detach from the lower mold, providing the operator with sufficient operating space to easily remove the air conditioning panel.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example
[0019] like Figure 1-2As shown, an embodiment of the present invention provides an anti-deformation injection mold for an air-conditioning panel, comprising a base 1, a servo motor 4, a cooling box 12, a cooling pipe 13 and a fan blade group 16. Two fixed plates 2 are fixedly connected to the top of the base 1, a connecting plate 3 is fixedly connected between the two fixed plates 2, the servo motor 4 is fixedly connected to the top of the connecting plate 3, a screw rod 5 is fixedly connected to the driving end of the servo motor 4, an injection molding device 6 is threadedly connected to the outer surface of the screw rod 5, an upper mold 7 is fixedly connected to the bottom of the injection molding device 6, the upper mold 7 is located in front of the screw rod 5, a lower mold 8 is fixedly connected to the top of the base 1, the lower mold 8 is located between the two fixed plates 2, the upper mold 7 is fitted with the lower mold 8, a fixing rod 9 is fixedly connected to the bottom of the connecting plate 3, and the fixing rod 9 penetrates and is connected with A placing plate 10 and a cooling box 12 are installed on the top of the placing plate 10, and a cooling pipe 13 is installed at the bottom of the cooling box 12. The cooling pipe 13 is composed of a connecting pipe and an annular pipe. The annular pipe sleeve of the cooling pipe 13 is arranged on the outer surfaces of the upper mold 7 and the lower mold 8. A worm 14 is arranged on one side of the lower mold 8. The two ends of the worm 14 are respectively located at the base 1 and the connecting plate 3 for rotation connection. The top of the screw 5 and the top of the worm 14 are both penetrated and fixedly connected with a transmission wheel 17. The outer surfaces of the two transmission wheels 17 are sleeved with a transmission belt 18. One of the fixed plates 2 is rotatably connected to a rotating rod 15 near the side wall of the worm 14. The end of the rotating rod 15 near the lower mold 8 is fixedly connected to a worm wheel. The worm 14 is meshed with the worm wheel, and the fan blade group 16 is installed on the outer surface of the rotating rod 15.
[0020] The bottom end of the fixing rod 9 is fixedly connected with a fixing block 11, which contacts the bottom of the placing plate 10. The cooling box 12 on the placing plate 10 is supported by the fixing block 11, so that the placing plate 10 maintains a distance from the injection molding equipment 6, so that the injection molding equipment 6 can drive the cooling box 12 only after moving upward a certain distance, and then the cooling tube 13 can be separated from the lower mold 8.
[0021] The limit rod is fixedly connected between the base 1 and the connecting plate 3, which can effectively limit the moving range of the injection molding device 6 and ensure that the screw rod 5 can move smoothly along the predetermined track when driving the injection molding device 6.

Such a layout not only enhances the guiding property of the mold, but also improves the durability and safety of the mold.
[0022] The placement plate 10 is located directly above the injection molding device 6. This design allows the injection molding device 6 to easily drive the placement plate 10 and the cooling tube 13 assembly thereon to move upward after the injection molding is completed, thereby smoothly realizing the mold opening and part removal operations. At the same time, the placement plate 10 also plays a role in supporting and fixing the cooling tube 13, ensuring the smooth progress of the cooling process.
[0023] The central axis of the rotating rod 15 is located on the contact surface of the upper mold 7 and the lower mold 8. This design ensures that the fan blade group 16 can evenly dissipate heat from the cooling pipe 13 when rotating. The fan blade group 16 is located on one side of the cooling pipe 13. The rotation of the fan blades generates airflow, which accelerates the heat dissipation on the surface of the cooling pipe 13, thereby improving the cooling efficiency. This layout not only optimizes the heat dissipation effect, but also reduces energy consumption.
