Description

Technical Field

[0001] This application relates to the field of injection molds, and more specifically, to an injection mold for air suspension. Background Technology

[0002] With social development and technological progress, the scope and quantity of injection molded parts are increasing, and people's lives are becoming more and more inseparable from the use of injection molded parts, especially the use of injection molded automotive parts. Molds are an indispensable process in modern industry, especially in the automotive, radio, electrical machinery, instrumentation and meter industries.

[0003] Existing injection molds for automotive parts require a long time to demold. The molten plastic needs to cool and solidify during demolding, which results in a long demolding time.

[0004] Chinese patent application CN202222926363.0 discloses an injection mold for automotive parts. By cooperating with refrigeration boxes on both sides of the housing and an air refrigeration device, the air can be cooled. The cooled air is then introduced into the housing through a connecting cylinder to cool the mold inside the housing, allowing the workpiece to be formed quickly. The cooperation of a second electric push rod and a lower pressure plate makes it easier to remove the workpiece. This solves the problem that existing automotive parts injection molds require a long demolding time, and the molten plastic needs to cool and solidify during demolding, resulting in a long demolding time.

[0005] The above solution also has the following shortcomings: When in use, the upper pressure plate is fixedly connected to the suspension plate, and the lower pressure plate is fixedly connected to the movable end of the electric push rod. When it is necessary to disassemble and replace the mold, it is very inconvenient, thus reducing the practicality of the device. At the same time, the support platform and the suspension plate are not easy to buffer during the connection process, thus reducing the service life of the device and reducing its practicality.

The arrangement of the rotating shaft 1941, the fixing plate 1942, and the cleaning brush 1943 facilitates the cleaning of the filter screen 1910, thus avoiding any impact on the filtration effect.

[0040] In the specific setup, support legs are provided at the four corners of the bottom of the housing 110. By providing support legs at the four corners of the bottom of the housing 110, the device can be easily supported at a suitable height, making it convenient for users to use.

[0041] Please see Figure 1 and Figure 3 The protective structure 20 includes a fixed frame 210, a sliding rod 220 and a spring 230. The fixed frame 210 is disposed inside the housing 110.

The lifting assembly 130 is in contact with the sliding rod 220.

[0042] The working principle of this air suspension injection mold is as follows: When using the air suspension injection mold, the upper mold 140 and the first mounting plate 160 are connected to the lifting plate 132 via the screw 180, and the lower mold 150 and the second mounting plate 170 are connected to the heat-conducting frame 121 via the screw 180, facilitating the disassembly and replacement of the upper mold 140 and the lower mold 150, thus improving the practicality of the device. By activating the electric push rod 131, the lifting plate 132 and the upper mold 140 are moved, facilitating the connection between the upper mold 140 and the lower mold 150. During the movement, the lifting plate 132 contacts the downward sliding rod 220 and compresses the spring. Spring 230 helps reduce the impact when the upper mold 140 and lower mold 150 are connected, extending the service life of the injection mold. After injection molding, external water enters the circulation pipe 123 through the water inlet pipe 122 and is discharged through the water outlet pipe 124, facilitating the cooling of the injection molded product. By turning on the dual-axis motor 194 to drive the fan blade 195 to rotate, the injection molded product is further cooled, improving the cooling efficiency. At the same time, the dual-axis motor 194 drives the rotating shaft 1941, the fixing plate 1942 and the cleaning brush 1943 to rotate, facilitating the cleaning of the filter screen 1910 and avoiding affecting the filtration effect.

[0043] It should be noted that the specific model specifications of the electric actuator 131 and the dual-axis motor 194 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0044] The power supply and operating principle of the electric actuator 131 and the dual-axis motor 194 are clear to those skilled in the art and will not be described in detail here.

[0045] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
