Description

Technical Field

[0001] This utility model relates to the field of lost foam casting technology, specifically to a deformation-resistant support device that is easy to assemble and disassemble. Background Technology

[0002] Lost foam casting of aluminum parts is a highly efficient casting process mainly used in the production of aluminum alloy parts. The core of this casting process lies in using foam plastic to create the lost foam pattern.

[0003] Chinese patent CN222307286U discloses a sand box for sand casting of machine tool parts. During the assembly process, the upper sand box is placed on the lower sand box. The positioning notch on the upper box lug can cooperate with the positioning protrusion on the lower box lug to achieve positioning and alignment. At the same time, the positioning frame is embedded in the positioning groove, and the outline of the positioning frame is the same as the outline of the upper sand box. Thus, after the positioning frame is embedded in the positioning groove, the upper and lower sand boxes can achieve positioning and alignment in the horizontal direction. However, for the production of complex parts, multiple layers of sand boxes need to be stacked and assembled to facilitate casting and demolding operations. If this sand box is used, it will be detrimental to the mold assembly and demolding operations, reducing production efficiency.

[0004] Based on this, the present invention designs an anti-deformation support device that is easy to assemble and disassemble to solve the above problems. Utility Model Content

[0029] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-5 A deformation-resistant support device that is easy to assemble and disassemble, comprising a sand box body 1;

[0030] The cross-section of the sand box body 1 is a closed rectangle. The sand box body 1 is composed of a first side frame 11 and a second side frame 12. One end of the first side frame 11 and the second side frame 12 are hinged to each other. A locking mechanism 3 is provided between the other ends of the first side frame 11 and the second side frame 12. The locking mechanism 3 is used to control the locking after the first side frame 11 and the second side frame 12 are closed.

[0031] The connecting components are located at the upper and lower ends of the sand box body 1 and are used to control the assembly of adjacent sand box bodies 1.

[0032] The first frame 11 is also provided with a linkage mechanism 4, which is used to control the locking mechanism 3 of the adjacent sand box body 1 after combination to synchronously unlock and lock the sand box body 1.

[0033] In this utility model, the operator selects an appropriate number of sand box bodies 1 according to the requirements of the lost foam specifications. The sand box bodies 1 are assembled into a whole by connecting components. After the lost foam and filling sand are placed inside, the casting operation is carried out. After the casting is completed, the locking mechanism 3 of the top sand box body 1 is unlocked. When the locking mechanism 3 is unlocked, it will drive the locking mechanisms 3 of all sand box bodies 1 to unlock synchronously through the linkage mechanism 4. At this time, the connection between the first frame 11 and the second frame 12 can be opened, realizing the synchronous opening and closing of all sand box bodies 1, which is conducive to the demolding operation of the product.

[0034] The connecting component includes a plug 5 and a slot 6. The plug 5 is symmetrically fixedly installed on the upper end of the first frame 11 and the second frame 12.

When multiple sand box bodies 1 are combined, adjacent sand box bodies 1 are connected by plugging in the plug 5 and the slot 6 to form a whole, which is convenient for hoisting equipment or transfer equipment to transport as a whole.

[0035] Please see Figure 4 and Figure 5 The locking mechanism 3 includes a first housing 31, a second housing 32, a first semicircular block 33, a second semicircular block 34, and a lever 35. The first housing 31 is fixedly installed on the side of the first frame 11, and the second housing 32 is fixedly installed on the side of the second frame 12. When the first frame 11 and the second frame 12 are closed, the first housing 31 and the second housing 32 are spliced ​​together to form a circular block. The first semicircular block 33 and the second semicircular block 34 are respectively provided inside the first housing 31 and the second housing 32, and the first semicircular block 33 and the second semicircular block 34 are both limited and slidably connected to the inner side of the first housing 31 and the second housing 32. The side walls of the first housing 31 and the second housing 32 are provided with grooves 36 for avoiding the lever 35, and the lever 35 is fixedly installed on the side walls of the first semicircular block 33 and the second semicircular block 34.

[0036] In this invention, the first semicircular block 33 and the second semicircular block 34 can be controlled to rotate synchronously by moving the lever 35. When the first semicircular block 33 and the second semicircular block 34 are fully contained by the first housing 31 and the second housing 32 respectively, the first frame 11 and the second frame 12 are in the unlocked state. When the first semicircular block 33 and the second semicircular block 34 rotate 90 degrees, the first semicircular block 33 and the second semicircular block 34 maintain an attitude in which half of them are located in the first housing 31 and the other half is located in the second housing 32. The first frame 11 and the second frame 12 are in the locked state, which is not only convenient to operate, but also has a good locking effect.

[0037] The linkage mechanism 4 includes a linkage component 41 and a drive component 42. The linkage component 41 is installed on the side of the sand box body 1, and the drive component 42 is installed between the linkage component 41 and the lever 35. The linkage component 41 is used to control the locking mechanism 3 of the adjacent sand box body 1 to unlock and lock synchronously, and the drive component 42 is used to transmit power between the lever 35 and the linkage component 41.

[0038] The linkage assembly 41 includes a sliding cylinder 411, a sliding column 412, a spring 413, and a fixing ring 414. The sliding cylinder 411 is fixedly installed at the lower end of the sand box body 1. The lower end of the sliding column 412 is slidably connected to the inner side of the sliding cylinder 411. The upper end of the sliding column 412 is fixedly installed with the fixing ring 414. The spring 413 is sleeved on the outer side of the sliding column 412. The two ends of the spring 413 are fixedly connected to the sliding cylinder 411 and the fixing ring 414, respectively. Through holes are provided at both the upper and lower ends of the sand box body 1 to accommodate and avoid the sliding column 412.

[0039] The drive assembly 42 includes a linkage rod 421 and a linkage pin 422. The linkage pin 422 is fixedly installed on the side wall of the slide column 412. The side wall of the slide cylinder 411 is provided with a second slide groove 424 that is slidably connected to the linkage pin 422. The linkage rod 421 is fixedly connected to any lever 35. The linkage rod 421 is provided with a first slide groove 423 that is slidably connected to the linkage pin 422.

[0040] In this invention, the lever 35 is pushed down to unlock the first frame 11 and the second frame 12. The lever 35 causes the sliding column 412 to slide vertically downward in the slide cylinder 411 through the linkage rod 421 and the linkage pin 422. The sliding column 412 on each sand box body 1 will push the sliding column 412 of the next layer downward. The sliding column 412 will in turn drive the lever 35 of that layer to be pushed down through the linkage rod 421 and the linkage pin 422, thereby realizing the synchronous unlocking of all sand box bodies 1 and effectively improving production efficiency.
