A matching groove with the same shape as the through groove is opened in the middle of the hollow boss. One of the locking pins of the quick-lock handle passes through the matching groove and the through groove of one template and the through groove and the matching groove of the other template in turn. At this time, the two locking pins are respectively in contact with the outer sides of the hollow bosses of the two templates, and the two locking pins can be driven to rotate by rotating the hand-held section, so that the two templates move toward each other and are locked.

[0006] Furthermore, when the locking pin passes through the template, the axis of the locking pin is parallel to the line connecting the upper and lower ends of the through slot; when the quick-lock handle is in a locked state, the axis of the locking pin is perpendicular to the line connecting the upper and lower ends of the through slot.

[0007] Furthermore, the hollow boss is formed by splicing a left boss and a right boss, the thickness of the left boss gradually increases from top to bottom from being flush with the surface of the template, and the thickness of the right boss gradually increases from bottom to top from being flush with the surface of the template.

[0008] Furthermore, the thickness of the left bump and the right bump increase at the same rate.

[0009] Furthermore, the handle body is a hot stamping part, and the handle body is bent into the hand-holding section and the locking section which are perpendicular to each other.

[0026] The technical solutions provided by various embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0027] Example 1

[0028] like Figures 1 to 5 As shown, the fixing structure of the casting template of Example 1 of the present invention includes two templates 1 that need to be fixed together and a quick-lock handle 2.

[0029] Among them, the quick-lock handle 2 includes a handle body 3 and two identical locking pins 4. The handle body 3 is cylindrical and is divided into two sections perpendicular to each other, one of which is a hand-holding section and the other is a locking section. The two locking pins 4 respectively pass through the through holes on the locking section and are fixed at positions near the two ends of the locking section.

[0030] In addition, the template 1 is provided with a through slot 7 penetrating the thickness of the template, and the middle section of the through slot 7 is expanded into a partial circle Y. The length and width of the through slot 7 are respectively adapted to the length and diameter of the locking pin 4, and the diameter of the partial circle Y is adapted to the diameter of the handle body 3, that is, the through slot 7 is used for a locking pin 4 and a locking section of the quick-locking handle 2 to pass through the template 1.

[0031] In this embodiment 1, on the non-contact surface of the template 1, a hollow boss coaxial with the through slot 7 and with a through slot of the same shape as the through slot 7 in the middle is arranged around the through slot 7 with the center of the partial circle Y as the center, and the hollow boss is spliced ​​by a left boss 5 and a right boss 6, one end of the through slot 7 is defined as the top, and the other end is defined as the bottom, the thickness of the left boss 5 gradually bulges from top to bottom from being flush with the surface of the template 1, and the thickness of the right boss 6 gradually bulges from bottom to top from being flush with the surface of the template 1, and the rate of increase of the thickness of the two bosses is exactly the same.

[0032] At this time, the straight-line distance between the two locking pins 4 on the quick-lock handle 2 is recorded as L, and L is set as follows: the contact surfaces of the two templates 1 are fitted and the corresponding two through grooves 7 are aligned. When the two locking pins 4 of a quick-lock handle 2 are respectively located on the outside of the hollow bosses of the two templates 1 through the above-mentioned two through grooves 7, and the locking pins 4 are rotated to the left to contact the protrusions of the two hollow bosses, the two templates 1 are gradually locked.

[0033] When in use, the contact surfaces of the two templates 1 are fitted together and the two through grooves 7 are aligned, and then a locking pin 4 on the quick-lock handle 2 passes through the through grooves 7 on the two templates from the non-contact surface of one template 1 to the non-contact surface of the other template 1, that is, the two locking pins 4 are respectively located outside the hollow bosses on the non-contact surfaces of the two templates 1, and the two templates 1 can be quickly locked and fixed or quickly unlocked and disassembled by turning the quick-lock handle 2 to the left or right.

[0034] In this embodiment 1, the handle body 3 is a hot stamping part, and then is bent into a hand-holding section and a locking section that are perpendicular to each other.

[0035] like Figure 6 As shown, the line connecting the upper and lower ends of the through slot 7 is recorded as the center line, and before insertion, the axis of the locking pin 4 is parallel to the center line. Due to the shape and size of the through slot 7, the locking pin 4 and the locking section of the handle body 3 can pass through the through slots 7 of the two templates and reach the non-contact surface of one template 1 from the non-contact surface of the other template 1.

[0036] like Figure 7 As shown, when locked, the axis of the locking pin 4 is perpendicular to the center line, that is, due to the gradually increasing thickness of the two protrusions, when the quick lock handle is rotated to the left to 90 degrees, it is locked.

[0037] Example 2

[0038] The method for fixing the casting template of the second embodiment adopts the fixing structure of the casting template, and comprises the following steps:

[0039] like Figure 7 As shown, when it is necessary to lock and fix two templates 1 to be fixed, the contact surfaces of the two templates 1 are fitted together, and the through slots 7 of the two templates 1 are aligned, and a locking pin 4 of the quick lock handle 2 is passed through the through slots 7 on the two templates 1 from the non-contact surface of one template 1 to reach the non-contact surface of the other template 1, that is, the two locking pins 4 are respectively located outside the hollow bosses on the non-contact surfaces of the two templates 1. At this time, the two templates 1 are locked and fixed by rotating the quick lock handle 2; Figure 6 As shown, when it is necessary to unlock and disassemble the two locked and fixed templates 1, the two templates 1 are unlocked by rotating the quick-lock handle 2 in the opposite direction, and a locking pin 4 of the quick-lock handle 2 is taken out from the non-contact surface of the other template 1 through the through groove 7 on the two templates 1, so that the two templates 1 can be disassembled.

[0040] The fixing structure and fixing method of the casting template of the present invention provide a quick-locking handle and a hollow boss, so that the casting template can be quickly locked, fixed and unlocked without the aid of any external tools while ensuring the quality of the operation, thereby reducing the difficulty of on-site construction, improving the operation efficiency, and having a good effect. In addition, the fixing structure adopted by the present invention is compact and easy to manufacture.

[0041] The embodiments described above are only descriptions of the preferred modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
