Description

Technical Field

[0001] The invention relates to the technical field of air conditioner shell molds, and more specifically to an air conditioner shell injection molding mold. Background Art

[0002] The injection molding mold for air conditioner shell is a special mold used to manufacture air conditioner shells; injection molding is a molding method in which thermoplastic plastics or thermosetting plastics are melted by heating, injected into the mold cavity under high pressure, and then cooled and solidified to obtain plastic products; and the injection molding mold for air conditioner shell is a specific mold designed for molding air conditioner shells.

[0003] In the existing injection molding mold of the air conditioner shell, the electric heating element installed inside the mold is usually used to generate heat to heat the entire mold, so that the plastic melt can have good fluidity in the mold cavity. After the plastic melt fills the cavity, the electric heating element is turned off, and then the mold is cooled by the cooling system to cool the plastic melt in the cavity. However, although the electric heating element is turned off, its own residual heat still has a thermal effect on the mold, which makes the cooling time longer and the cooling efficiency lower during the cooling operation, further lengthening the entire production cycle and reducing production efficiency. For the production of air conditioner shells that need to be quickly molded, the switching time may become a production bottleneck, affecting the production capacity and market competitiveness of the enterprise. In view of this, we propose an injection molding mold for air conditioner shells. Summary of the invention

[0015] A method for using an injection molding mold for an air conditioner housing comprises the following steps:

[0016] S1, heating operation, connecting the terminal block through the external heating system, heating the heating wire, the heating wire heats the heating plate, the heating plate heats the central mold, the central mold transfers heat to the first side mold and the second side mold, so that the movable mold assembly can maintain a heated state;

[0017] S2, injection molding operation, injecting plastic melt into the injection molding tube through external injection molding equipment, and the plastic melt enters the air conditioner outer shell cavity through the injection molding tube. The continuously heated movable mold component can ensure the molten state of the plastic melt in the air conditioner outer shell cavity, thereby maintaining fluidity, so that the plastic melt fills the entire air conditioner outer shell cavity;

[0018] S3, cooling and molding operation, the heating operation of the heating wire is turned off through the external heating system, and then the motor 2 is operated to drive the rotating rod to rotate, the rotating rod drives the screw to rotate through the meshing bevel gear 1 and bevel gear 2, the screw drives the lifting cylinder to rise, the lifting cylinder drives the heating component to rise through the structural plate and the connecting rod, so that the heating component stops rising after leaving the inner cavity of the central mold, and the inner cavity of the central mold forms a cooling channel, and the external cold air equipment inputs cold air into the cooling pipe, the cold air enters the blowing channel through the cooling pipe, and further enters multiple branch channels through the output end of the blowing channel, and enters the cooling channel from the output end of the branch channel. The cold air is blown upward along the bottom surface of the cooling channel and enters the external environment, continuously taking away the heat on the central mold, and further taking away the heat in the cavity of the air conditioner shell body, so that the plastic melt is cooled and molded;

[0019] S4, demoulding operation, after the plastic melt is cooled and formed, the motor 2 continues to work to drive the screw to rotate, so that the lifting cylinder continues to rise, and the heating component continues to rise. During the rising process of the heating component, the slide plate moves upward relative to the slider through the sliding groove until the bottom surface of the sliding groove of the slide plate contacts the bottom surface of the slider. The slide plate drives the slider to rise through the sliding groove, and the slider drives the center mold to rise until the center mold is separated from the first side mold and the second side mold. The motor 1 works to drive the rotating column to rotate, and the rotating column drives the moving block 1 and the moving block 2 to move toward each other through the two reverse external threads on its circumferential outer wall, further driving the first side mold The first side mold and the second side mold move toward each other to form a combined state. During the movement of the first side mold and the second side mold, the air-conditioning shell formed by cooling in the air-conditioning shell cavity is separated laterally to avoid damaging the structure of the inner wall of the air-conditioning shell. Then, the lifting cylinder continues to rise, driving the L-shaped structure at the bottom of the hook plate to hook the bottom surface of the support plate, driving the support plate to rise, and further driving the first side mold and the second side mold in the combined state to rise, and then the hydraulic cylinder works to push the ejection mold to slide upward from the square groove of the fixed mold. The ejection mold pushes the air-conditioning shell to leave the inner cavity of the fixed mold and enter above the fixed mold. The demoulding operation is completed, and the air-conditioning shell can be removed.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The lifting assembly in the present invention can make the heating assembly and the central mold of the movable mold assembly form a merged state or a separated state through the linkage assembly. In the merged state, the heating assembly is in full contact with the inner cavity of the central mold to improve the heating effect. The heating assembly heats the movable mold assembly to keep the plastic melt in a molten state in the cavity of the air-conditioning outer shell, thereby maintaining fluidity and filling the entire air-conditioning outer shell cavity. In the separated state, the heating assembly is away from the inner cavity of the central mold, and a cooling channel is formed in the inner cavity of the central mold. The external cold air equipment inputs cold air into the cooling channel through the cooling pipe to cool the central mold, thereby cooling the movable mold assembly and solidifying the plastic melt in the cavity of the air-conditioning outer shell. The residual heat on the heating assembly during cooling effectively avoids affecting the cooling effect. By separating the heating assembly from the central mold, the cooling efficiency is improved, the production cycle is shortened, and the production efficiency is further improved.

[0022] 2. The present invention also designs two limit plates on the bottom surface of the fixed mold, and four slide bars are connected to the bottom surface of the ejection mold. The slide bars and the slide grooves of the limit plates slide in cooperation with each other, so that when the ejection mold slides upward in the square groove, the ejection mold is limited by the slide bars and can always keep sliding vertically upward, thereby improving the sliding stability of the ejection mold. Moreover, when the ejection mold enters the square groove downward for resetting, the bottom surface of the ejection mold is limited by the two limit plates, so that it can fit into the square groove more accurately.

[0023] 3. The present invention also provides an arc concave structure corresponding to the outer shape of the center mold on the inner walls of the first side mold and the second side mold, so that when the first side mold, the second side mold and the center mold are combined, the overall structure is relatively tight and can shape the inner shape of the air-conditioning shell. In addition, the arc concave structure of the inner walls of the first side mold and the second side mold can expand the contact area with the outer wall of the center mold, thereby improving the effect of the center mold in transferring heat or cooling the first side mold and the second side mold.

[0024] 4. The present invention also designs a synchronous transmission component. The rotating column of the synchronous transmission component drives the moving block 1 and the moving block 2 to move toward or away from each other through two reverse external threads on its circumferential outer wall, and further drives the first side mold and the second side mold to move toward or away from each other to form a merged state or a separated state. When the first side mold and the second side mold move toward each other, they are laterally separated from the cooled and formed air-conditioning shell in the air-conditioning shell cavity to avoid damaging the structure of the inner wall of the air-conditioning shell. Then, the first side mold and the second side mold in the merged state are separated from the air-conditioning shell cavity, and the cooled and formed air-conditioning shell is demolded. When the first side mold and the second side mold move away from each other, the center mold can be inserted between the first side mold and the second side mold. The three form a complete movable mold component, which is used to cooperate with the fixed mold component so that the space between the fixed mold component and the movable mold component forms the air-conditioning shell cavity.

[0025] 5. In the present invention, when the screw rod of the lifting assembly rotates to drive the lifting cylinder to rise, the connecting rod of the linkage assembly can be used to drive the heating assembly to rise, so that the heating assembly leaves the inner cavity of the central mold, which is convenient for cooling the central mold. When the lifting cylinder continues to rise, it can further drive the heating assembly to rise, and the slide plate of the heating assembly drives the slider to rise through the sliding groove, and the slider drives the central mold to rise, so that the central mold and the first side mold and the second side mold form a separated state, and then the first side mold and the second side mold are moved toward each other through the synchronous transmission assembly to form a merged state, and then the lifting cylinder continues to rise, so that the L-shaped structure at the bottom of the hook plate hooks the bottom surface of the support plate, drives the support plate to rise, and further drives the first side mold and the second side mold in the merged state to rise, completes the separation of the movable mold assembly and the fixed mold assembly, and facilitates the demoulding operation. Through the mutual cooperation of the lifting assembly, the synchronous transmission assembly and the linkage assembly, the heating assembly and the movable mold assembly are intermittently linked to each other. The transmission operation can meet the requirements of the movement form of the heating assembly and the movable mold assembly in multiple use stages, thereby improving the flexibility and convenience of the device.
