Description

Technical Field

[0001] The present application relates to the technical field of core manufacturing and design equipment, and in particular to a combined hot core box. Background Art

[0002] The hot core box method is a method of machine-made cores in foundry production. Sand mixed with casting sand, thermosetting resin and curing agent is injected into a core box with a heating device and heated to about 200 degrees. The sand close to the surface of the core box is heated. Under the action of high temperature, the binder can be condensed and hardened in a very short time to form a core.

[0003] However, after the core is manufactured, how to safely and efficiently remove it from the hot core box has become an urgent problem to be solved. Since the hot core is located between the upper core box and the lower core box, its natural cooling rate is relatively slow. If the staff directly touches and tries to remove these high-temperature hot cores, it is not only easy to cause burns, but also poses a great safety hazard. Therefore, how to ensure the safety of the staff while ensuring production efficiency has become an important technical issue that needs to be faced in the current application of the hot core box method.

DETAILED DESCRIPTION

[0027] The following is combined with Figure 1-2 This application is described in further detail.

[0028] The embodiment of the present application discloses a combined hot core box.

[0029] like Figure 1 As shown, a combined hot core box comprises an upper core box 1, a lower core box 2 which can be combined with the upper core box 1, and a clamping assembly 3, wherein the clamping assembly 3 comprises a base 31, a driving assembly 32 connected to the base 31, a cross bar 33 driven up and down by the driving assembly 32, a mounting frame 34 fixedly connected to the cross bar 33, a first hydraulic cylinder 35 fixedly mounted on one side of the mounting frame 34, a second hydraulic cylinder 36 fixedly mounted on the other side of the mounting frame 34, a first clamping plate 37 fixedly connected to the output shaft of the first hydraulic cylinder 35, and a second hydraulic cylinder 36 fixedly mounted on the output shaft of the second hydraulic cylinder 36. The second clamping plate 38 connected, the first clamping plate 37 and the second clamping plate 38 can clamp the two sides of the upper core box 1 and under the action of the driving assembly 32, the cross bar 33 drives the upper core box 1 to move upward to expose the hot core between the upper core box 1 and the lower core box 2. The first clamping plate 37 and the second clamping plate 38 can also clamp the upper core box 1 and put it back to its original position. The base 31 serves as the supporting basis of the entire clamping assembly 3, and a vertical rod 311 is fixedly installed on its upper surface. The driving assembly 32 is fixedly connected to the top of the vertical rod 311, which is used to drive the cross bar 33 to move up and down.

[0030] When the hot core needs to be taken out, the first clamping plate 37 and the second clamping plate 38 are first driven by the first hydraulic cylinder 35 and the second hydraulic cylinder 36 to clamp the upper core box 1. Then, the driving assembly 32 drives the cross bar 33 to move upward, thereby driving the upper core box 1 to move upward, revealing the hot core between the upper core box 1 and the lower core box 2. The hot core is exposed to the outside air, which increases the cooling speed while preventing the staff from directly contacting the high-temperature upper core box 1 and the high-temperature hot core, reducing the risk of burns.

[0031] The driving assembly 32 is a hydraulic cylinder assembly, which has the advantages of simple structure, reliable operation, and large output force. It can stably drive the cross bar 33 and the clamping plate to move up and down. In practical applications, other types of driving assemblies 32, such as cylinder assemblies, can also be selected as needed.

[0032] like Figure 1 As shown, the first clamping plate 37 and the second clamping plate 38 are fixedly connected with a high-temperature resistant anti-skid pad 4, which can increase the friction between the clamping plate and the upper core box 1 to prevent slipping during the clamping process. At the same time, the high-temperature resistant anti-skid pad 4 can also withstand high temperature environment to ensure stability during long-term use.

[0033] like Figure 1 and Figure 2 As shown, both sides of the lower core box 2 are fixedly connected with limit blocks 5, which are arranged vertically. The limit blocks 5 can limit the left and right deviation of the lower core box 2 when it moves up and down, thereby ensuring the alignment accuracy between the upper core box 1 and the lower core box 2.

[0034] like Figure 1 and Figure 2 As shown, a combined hot core box also includes a cooling component 6, which includes a fan 61 fixedly connected to the vertical rod 311, an air supply pipe 62 fixedly connected to the fan 61 and covering the fan 61, and a support rod 63 connected to the vertical rod 311 for supporting the air supply pipe 62, and the pipe mouth of the air supply pipe 62 is aligned with the hot core.

[0035] The present application uses the fan 61 to blow cold air through the air supply pipe 62 toward the hot core, so that the hot core can be cooled down quickly, thereby improving production efficiency and further ensuring the safety of the staff. The present application adjusts the position of the air supply pipe 62 so that the pipe mouth of the air supply pipe 62 is aligned with the hot core, and the cold air blown out by the fan 61 accurately and quickly cools the hot core, thereby improving production efficiency.

[0036] The air supply pipe 62 is a retractable plastic pipe. One end of the support rod 63 is fixedly connected to the air outlet of the air supply pipe 62 . The support rod 63 can cooperate with the air supply pipe 62 to retract.

[0037] The air supply pipe 62 is designed as a retractable structure, and the support rod 63 can also move in conjunction with the extension and retraction of the air supply pipe 62. Therefore, the length and position of the air supply pipe 62 can be adjusted according to the actual position and height of the hot core to ensure that the cold air can be accurately blown to the hot core.

[0038] like Figure 1 and Figure 2 As shown, the support rod 63 includes a first support rod 631 and a second support rod 632 connected to the first support rod 631. The first support rod 631 is hinged to the vertical rod 311, and the second support rod 632 is hinged to the air outlet of the air supply pipe 62. A slide groove 7 is provided at one end of the first support rod 631 close to the second support rod 632. The second support rod 632 can slide in the slide groove 7. A threaded hole 8 is provided on the first support rod 631. The bolt is screwed into the threaded hole 8 to tighten the second support rod 632, thereby fixing the first support rod 631 and the second support rod 632.

[0039] With this structure, the height and position of the air supply pipe 62 can be easily adjusted. At the same time, a threaded hole 8 is also provided on the first support rod 631, and the first support rod 631 and the second support rod 632 can be fixed together by screwing a bolt into the threaded hole 8 to ensure the stability of the air supply pipe 62.

[0040] The implementation principle of a combined hot core box in the embodiment of the present application is as follows: when the hot core needs to be taken out, the driving assembly 32 is started to make the installation frame 34 fall down. When the upper core box 1 is located in the installation frame 34, the first hydraulic cylinder 35 and the second hydraulic cylinder 36 are started. The first hydraulic cylinder 35 and the second hydraulic cylinder 36 control the first clamping plate 37 and the second clamping plate 38 to clamp the upper core box 1. The driving assembly 32 controls the upper core box 1 to move upward so as to expose the hot core between the upper core box 1 and the lower core box 2. The fan 61 is started to quickly cool the hot core. After the cooling is completed, the hot core is taken out. The driving assembly 32, the first hydraulic cylinder 35, the second hydraulic cylinder 36, the first clamping plate 37 and the second clamping plate 38 are used in combination to put the upper core box 1 back to its original position.

[0041] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
