[0002] Container corner fittings are an important part of the container structure and are usually made of steel or reinforced plastic. Container corner fittings are located at the four corners of the container. Their main functions include fixing and connecting the top, bottom, side walls and door panels of the container, thereby ensuring the structural stability of the container and the safety of the goods during transportation. At present, the common container corner fittings we have are usually completed by casting, which uses casting molds; however, the existing mold device is slow when demolding, and semi-automatic operation and demolding are required manually with the help of tools. This is inefficient and will affect the continuous use of the mold and production efficiency. Utility Model Content

In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0019] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0020] Figure 1-Figure 3 The utility model shows a schematic diagram of the entire structure of a container corner casting mold that is easy to demould. Figure 1-Figure 3 A container corner casting mold that is easy to demold in this embodiment includes a lower mold 1, an upper mold 6 is matched at the upper end of the lower mold 1, a plurality of mold grooves 101 are provided on the upper part and inner side of the lower mold 1, a positioning groove 102 is provided at the bottom of the mold groove 101, and a mounting cavity 103 is provided at the lower part of the lower mold 1 and is vertically connected to the bottom of the positioning groove 102; a demolding mechanism is provided inside the mounting cavity 103, and the demolding mechanism includes a push plate 2 arranged inside the mounting cavity 103, a top block 201 embedded in the inner side of the positioning groove 102, an elastic top piece 202 connected to the bottom of the top block 201 at one end and connected to the top of the push plate 2 at the other end, a plurality of cylinders 203 vertically installed at the bottom of the mounting cavity 103 and with output shafts connected to the bottom of the push plate 2, and a vibration motor 204 arranged at the bottom of the push plate 2.

[0021] Furthermore, multiple cylinders 203 are commonly connected to an air circuit pipe 2031, and one side of the lower mold 1 is also provided with an avoidance hole for facilitating the outward extension of the air circuit pipe 2031. Here, multiple cylinders 203 are provided for supporting the push plate 2, so that the push plate 2 can rise and fall stably. The outer end of the air circuit pipe 2031 is connected to an air circuit control device such as an air pump or an air tank, so that multiple cylinders 203 can be synchronously controlled during use, which is simple and easy to use.

[0022] Furthermore, the elastic top piece 202 is a spring telescopic rod, which has the characteristics of simple structure, good support stability and low cost. The good elastic support enables the top block 201 to form a certain buffer force when pushing the molded workpiece out of the mold, thereby greatly reducing the frustration force caused by demolding, and at the same time enhancing the vibration frequency, making the demolding process more stable.

[0023] Furthermore, a base plate 3 is provided below the installation cavity 103, which is embedded in the bottom of the lower mold 1 and is used to fix the cylinder 203. Here, the base plate 3 and the lower mold 1 are fixedly connected by threads. When disassembly and maintenance are required, only the base plate 3 needs to be removed to take out the cylinder 203 and other components at the same time, which is convenient for use and maintenance.

[0024] It can be understood that a groove is provided on one side of the top of the lower mold 1, a microcontroller 4 is arranged on the inner side of the groove, and a start-contact block 5 corresponding to the groove and the microcontroller 4 is arranged on one side of the bottom of the upper mold 6; wherein, the microcontroller 4 is signal-connected to the control end of the cylinder 203 and the vibration motor 204, and the upper part of the microcontroller 4 also has an opening and closing button vertically corresponding to the start-contact block 5. Here, in order to make the unloading mechanism more convenient and automatic when in use, specifically, when the upper mold 6 descends and closes with the lower mold 1, the start-contact block 5 will automatically contact the opening and closing button on the microcontroller 4, and the microcontroller 4 presets an extended start mode in advance. When the upper mold 6 completes the casting mold rising and the workpiece is formed at a specific time, the microcontroller 4 will start the cylinder 203 and the vibration motor 204 in time, thereby entering the automatic unloading stage, which is simple and practical to cooperate.

[0025] In summary, the present embodiment is a container corner casting mold that is easy to demold. When the workpiece needs to be demolded after forming, the control end will promptly start the cylinder 203 and the vibration motor 204. During this process, the push plate 2 will push the multiple elastic top pieces 202 and the top block 201 to gradually rise under the action of the cylinder 203. At the same time, the top block 201 will form high-frequency vibration and elastic pushing to the workpiece adhered to the inner side of the mold groove 101 with the cooperation of the elastic top piece 202 and the cylinder 203, so that gaps and separation are continuously generated between the workpiece and the mold until the workpiece is ejected from the mold groove 101. Multiple workpieces can be demolded uniformly at the same time, and the mutual cooperation makes the demolding operation more convenient and stable.

[0026] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
