[0002] The production of household appliance accessories is a complex process integrating design, mold manufacturing, raw material processing, post-treatment and assembly. It uses a variety of technologies such as injection molding, stamping, and die casting, aiming for high efficiency, precision and environmental protection to meet the diverse needs of household appliances and adapt to the development trend of intelligent manufacturing. Among them, the injection molding link is crucial in the production of household appliance accessories. It injects molten plastic into a mold under high pressure through a precise mold to achieve efficient, precise and customizable production, while promoting the efficient use of resources and environmentally friendly production. It is an indispensable core technology in modern household appliance manufacturing.

[0003] An injection mold for household appliance accessories is a mold specifically used to manufacture plastic accessories required in household appliances. During the injection molding process, the molten plastic is injected into the cavity of the mold under high pressure and forms plastic products with specific shapes, sizes and properties after cooling and solidification. These molds are usually made of high-quality steel and are precision machined and heat-treated to ensure their accuracy, durability and service life.

[0004] Existing injection molds for household appliance accessories have problems such as inability to perform assembly line operations, ineffective use of energy during injection molding, low cooling and temperature reduction efficiency, inability to adapt to different household appliance accessories, and lack of environmental protection during injection molding.

[0005] Based on this, we propose an injection mold for household appliance accessories, which can achieve assembly line injection molding operations such as high-efficiency spraying of release agent, mold closing, injection molding, cooling, mold opening, and discharging, with fast cooling and temperature reduction speed, energy conservation and environmental protection during the injection molding process, and can adapt to different household appliance accessories. Summary of the Utility Model

[0006] The purpose of the utility model is to address the above problems existing in the prior art and propose an injection mold for household appliance accessories. The technical problem to be solved by this utility model is: how to achieve efficient assembly line injection molding operations of spraying release agent, mold closing, injection molding, cooling, mold opening, and discharging, with fast cooling and temperature reduction speed, energy conservation and environmental protection during the injection molding process, and can adapt to different household appliance accessories.

[0007] The purpose of the utility model can be achieved by the following technical solutions:

[0008] An injection mold for household appliance accessories includes an injection table, on which an injection molding machine, a mold placement mechanism, and a hydraulic cylinder are successively arranged. One end of the mold placement mechanism is set on the hydraulic cylinder, and the other end is set on the injection molding machine. Inside the mold placement mechanism near one end of the injection molding machine, a fixed mold is provided. A spray lifting mechanism is arranged on the fixed mold and is connected to a mold release agent storage tank at the same time. A movable mold is slidably arranged inside the mold placement mechanism, and the position of the movable mold is opposite to that of the fixed mold. When the movable mold and the fixed mold are closed, a sealed injection space and a cooling channel are formed. The movable mold, the fixed mold, and the spray lifting mechanism are all connected to the injection table. An air suction and filtration box is arranged on the movable mold, and a fan is connected between the air suction and filtration box and the feeding part of the injection molding machine. The movable mold and the fixed mold are both connected to an electrostatic generator.

[0009] The working principle of the present utility model is as follows: Select a suitable fixed mold body and fixed mold plate according to the injection requirements, and select a suitable movable mold body and four movable mold plates according to the injection requirements;

[0010] Turn on the fan, the hydraulic cylinder drives the movable mold to move to a specified position on the sliding rod. The electrostatic generator provides static electricity for the movable mold and the fixed mold through connector one and connector two. The lifting screw member drives the hollow sliding table to reciprocate up and down once. The mold release agent storage tank provides the mold release agent for the spray lifting mechanism through one of the liquid inlets, and sprays it through the atomizing orifice on the atomizing member. Under the influence of static electricity, the mold release agent is effectively adsorbed inside the fixed mold and the movable mold. This is the mold release agent spraying action. The fan provides wind power for the air suction and filtration box, sucks the residual mold release agent in the air into the main body of the air suction box, and filters it through filter layers with different components;

[0011] The hydraulic cylinder pushes forward, so that the movable mold moves on the sliding rod towards the fixed mold until the movable mold body tightly abuts against the fixed mold body, forming a sealed injection space and a cooling channel. This is the mold closing action;

[0012] The injection molding machine heats the injection molding raw materials to a molten state and pours the molten injection molding raw materials into the injection space. The clean water collection tank injects cooling water into the cooling channel through a multi-way solenoid valve to cool the injection molding raw materials in the injection space.

After cooling for a certain time, the clean water collection tank stops injecting cooling water, and the pushing end of the hydraulic cylinder drives the movable mold to move backward on the sliding rod. This is the mold opening action;

The air suction and filtration box sucks out the generated water vapor and filters it through filter layers of different components to obtain clean hot air, which is sent into the feeding part of the injection molding machine to preheat the injection molding raw materials. At the same time, the air flow rate is increased to improve the cooling effect. This is the cooling and drying operation.

When the release agent is sprayed, the lifting lead screw member 801 drives the hollow sliding platform 802 to reciprocate up and down once. The release agent storage tank provides the release agent for the spray lifting mechanism 8 through one of the liquid inlets 805, and it is sprayed through the atomizing openings on the atomizing member 804, so that the release agent is adsorbed inside the fixed mold 5 and the moving mold 6.

[0070] When the cooling and drying operation is performed, the clean water collection tank provides clean water for the spray lifting mechanism 8 through the other liquid inlet 805. The lifting lead screw member 801 drives the hollow sliding platform 802 to reciprocate up and down once, and it is sprayed through the atomizing openings on the atomizing member 804 to effectively cool the fixed mold 5 and the moving mold 6.

[0071] The air suction and filtration box 7 includes an air suction box body. At least half of the air suction box body is exposed outside the moving mold body 604. A heat insulation pad is provided on the lower side of the air suction box body and is fixed on the moving mold body 604. A number of filter layers with different components are detachably provided inside the air suction box body. The air outlet of the air suction box body is connected to the injection molding machine 2 through a blower.

[0072] In this embodiment, the blower provides wind power for the air suction and filtration box 7, sucks the residual steam and waste water during spray cooling and release agent spraying into the air suction box body, and filters them through the filter layers with different components to obtain clean hot air, which is sent into the injection molding machine 2 to preheat the injection molding raw materials. At the same time, when the cooling and drying operation is performed, the air flow rate is increased to improve the cooling effect.

[0073] The working principle of the present utility model:

[0074] Select a suitable fixed mold body 501 and fixed mold plate 504 according to the injection molding requirements, and select a suitable moving mold body 604 and four moving mold plates 605 according to the injection molding requirements.

[0075] Turn on the fan, the hydraulic cylinder 3 drives the moving mold 6 to move to the designated position on the sliding rod 403. The electrostatic generator provides static electricity for the moving mold 6 and the fixed mold 5 through the first joint 506 and the second joint 603. The lifting screw member 801 drives the hollow slide 802 to reciprocate up and down once. The release agent storage tank provides the release agent for the spray lifting mechanism 8 through one of the liquid inlet ports 805, and sprays it through the atomizing ports on the atomizing member 804. Under the influence of static electricity, the release agent is effectively adsorbed into the fixed mold 5 and the moving mold 6. This is the release agent spraying action. The fan provides wind power for the air suction and filtration box 7, sucks the residual release agent in the air into the main body of the air suction box, and filters it through filter layers of different components;

[0076] The hydraulic cylinder 3 pushes forward, making the moving mold 6 move on the sliding rod 403 towards the fixed mold 5 until the moving mold body 604 tightly abuts against the fixed mold body 501, forming a closed injection molding space and cooling channel. This is the mold closing action;

[0077] The injection molding machine 2 heats the injection molding raw materials to a molten state and pours the molten injection molding raw materials into the injection molding space. The clean water collection tank injects cooling water into the cooling channel through the multi-way solenoid valve to cool the injection molding raw materials in the injection molding space. The output cooling water flows back to the clean water collection tank. After cooling for a certain time, the clean water collection tank stops injecting cooling water, and the pushing end of the hydraulic cylinder 3 drives the moving mold 6 to move backward on the sliding rod 403. This is the mold opening action;

[0078] After mold opening, the electric push rod drives the ejection plate 602 to move forward, and at the same time drives the ejection rod 606 to move forward, pushing out the formed product, which falls onto the inclined filter mesh plate 102 and slides away. After completion, the electric push rod drives the ejection plate 602 to reset, and at the same time drives the ejection rod 606 to reset. When mold opening, the air suction and filtration box 7 sucks out the waste gas and filters it through filter layers of different components to obtain clean hot air, which is sent into the injection molding machine 2 to preheat the injection molding raw materials;

[0079] The clean water collection tank provides clean water for the spray lifting mechanism 8 through the other liquid inlet port 805. The lifting screw member 801 drives the hollow slide 802 to reciprocate up and down once, and sprays water mist through the atomizing ports on the atomizing member 804 to effectively cool the fixed mold 5 and the moving mold 6. The air suction and filtration box 7 sucks out the generated water vapor and filters it through filter layers of different components to obtain clean hot air, which is sent into the feeding part of the injection molding machine 2 to preheat the injection molding raw materials. At the same time, it speeds up the air flow rate to improve the cooling and temperature reduction effect. This is the cooling and drying action. After completion, the release agent spraying action is repeated to prepare for the next injection molding.

[0080] In summary, through the spray lifting mechanism 8, the release agent is sprayed on the fixed mold 5 and the moving mold 6 before injection molding, and water mist is sprayed after injection molding for cooling;

[0081] Through the suction air filter box 7, the water vapor generated during the spray cooling process, the mold release agent remaining in the air when spraying the mold release agent, and the waste gas generated during mold opening are effectively collected and filtered, achieving greater environmental protection, saving water resources. At the same time, during the cooling and drying operation, the air flow rate is increased to improve the cooling and temperature reduction efficiency. By cooperating the suction air filter box 7 with the injection molding machine 2, the injection molding raw materials in the injection molding machine 2 are preheated to effectively utilize heat and be more energy-efficient;

[0082] By cooperating the fixed mold 5 with the moving mold 6, the mold can be quickly replaced according to production needs to adapt to different household appliance accessories, with higher production adaptability;

[0083] During cooling, the cooling water is sent out from the injection molding table 1, and through the cooling channels between the fixed mold 5 and the moving mold 6, effective cooling of the mold is achieved, and finally it flows back to the injection molding table 1 to realize water circulation. The injection molding table 1 collects and filters the water vapor generated during the spray cooling process, the mold release agent remaining in the air when spraying the mold release agent, and the water flowing out of the cooling channels during mold opening, saving water resources;

[0084] By cooperating the electrostatic generator, the fixed mold 5, the moving mold 6 with the spray lifting mechanism 8, the mold release agent is effectively adsorbed on the inner surface of the mold through static electricity.
