[0063] Research has found the shortcomings of the existing technology: in traditional technology, the floating insert and the lower bottom mold are fixed by threaded columns, but in the process of the upper mold repeatedly rising and falling and hitting the lower bottom mold, the threaded column will loosen, causing the floating insert to loosen, ultimately affecting the molding quality of the product.

[0064] Therefore, how to solve the stability of the fixing of the floating insert and the rapid disassembly is a technical problem that needs to be solved urgently in this field.

[0065] The defects existing in the above solutions are the results obtained by the inventor after practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed by the present invention in this article for the above problems should be the contributions made by the inventor to the present invention during the disclosure process.

[0066] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0067] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0068] like Figures 1 to 7 As shown, some embodiments provide a tray mold with a quickly removable floating insert 2, including:

[0069] The lower bottom mold 1 is arranged on a workbench, and is provided with a plurality of first positioning holes 10 adapted to the floating insert 2; the plurality of the first positioning holes 10 are arranged in a matrix; the floating insert 2 is provided with a plurality of second positioning holes 20, the bottom wall of which abuts against the upper surface of the lower bottom mold 1, and is suitable for limiting the mold; the floating insert 2 is a rectangular frame, and after the mold is placed in the floating insert 2, the limiting assembly 3 is sequentially inserted into the second positioning holes 20 and the first positioning holes 10 to achieve rapid fixation of the floating insert 2, and the mold is simultaneously limited and fixed. The limiting assembly 3 is arranged to be lifted and lowered in the first positioning hole 10, and is suitable for limiting the floating insert 2; wherein, the limiting assembly 3 passes through the floating insert 2 and is inserted into the first positioning hole 10 until it abuts against the bottom wall of the positioning hole, and the limiting assembly 3 is rotated circumferentially to limit the floating insert 2. By setting the limiting assembly 3, when fixing the floating insert 2, the limiting block 32 on the outer wall of the limiting column 31 and the adjusting block 36 on the outer wall of the buffer sleeve 35 are sequentially inserted into the limiting groove 12, thereby preventing the limiting column 31 from rotating in the opposite direction and causing the limiting block 32 to be separated from the limiting groove 12. When the limiting column 31 is separated from the first positioning hole 10 outward, the buffer sleeve 35 can also prevent impurities from entering the first positioning hole 10.

[0070] Reference Figure 4 Specifically, the limiting assembly 3 includes: a limiting column 31, whose outer wall is symmetrically fixed with two limiting blocks 32; the limiting blocks 32 are fixed at the lower part of the outer wall of the limiting column 31; a fixed plate 33, which is fixed at the upper end of the limiting column 31 and has a diameter greater than the inner diameter of the second positioning hole 20; the limiting column 31 moves downward to the fixed plate 33 and the floating insert 2, and after the limiting blocks 32 are inserted into the limiting groove 12, the limiting column 31 is suitable for limiting the floating insert 2. A linkage member 34 is arranged in the first positioning hole 10 and is arranged at the lower end of the limiting column 31; the linkage member 34 is a rubber member. When the limiting column 31 pushes the linkage member 34 to move into the first positioning hole 10, the side wall of the adjustment block 36 is squeezed and deformed by the inner wall of the first positioning hole 10; and when the adjustment block 36 moves into the limiting groove 12, the adjustment block 36 can be restored and the limiting block 32 can be reversely rotated. The limiting column 31 moves vertically downward until the fixed plate 33 abuts against the floating insert 2 , and the limiting column 31 is rotated circumferentially until the limiting block 32 is inserted into the limiting groove 12 to limit the floating insert 2 .

[0071] Furthermore, the diameter of the limiting column 31 is not greater than the inner diameter of the second positioning hole 20; the inner wall of the second positioning hole 20 is symmetrically provided with two second vertical grooves 21 along the axial direction, and the limiting block 32 is suitable for sliding in the second vertical grooves 21. When the limiting column 31 moves downward in the second positioning hole 20, the limiting block 32 moves downward along the second vertical grooves 21 synchronously. The inner diameter of the first positioning hole 10 is larger than the inner diameter of the second positioning hole 20; the inner diameter of the buffer sleeve 35 is larger than the diameter of the limiting column 31, the limiting column 31 is suitable for being inserted into the buffer sleeve 35, and the limiting column 31 is suitable for driving the buffer sleeve 35 to move up and down synchronously; the outer diameter of the buffer sleeve 35 is not larger than the inner diameter of the first positioning hole 10, and the buffer sleeve 35 is suitable for vertically moving up and down in the first positioning hole 10. When the buffer sleeve 35 is not inserted into the first positioning hole 10, the bottom wall of the adjustment block 36 on the outer wall of the buffer sleeve 35 abuts against the lower bottom mold 1. At this time, the buffer sleeve 35 is suitable for covering the first positioning hole 10 to prevent impurities from falling into the first positioning hole 10. When the buffer sleeve 35 is squeezed into the first positioning hole 10 by the limiting column 31, the adjustment block 36 is squeezed and deformed by the inner wall of the first positioning hole 10. The inner wall of the first positioning hole 10 is symmetrically provided with two first vertical grooves 11 along the axial direction, and a limiting groove 12 is provided on one side of the bottom wall of the first vertical groove 11, and the limiting block 32 is suitable for being inserted into the limiting groove 12. When the floating insert 2 is in contact with the lower bottom mold 1, the first vertical groove 11 is connected with the second vertical groove 21, and the limiting block 32 is suitable for moving from the second vertical groove 21 to the first vertical groove 11.

[0072] Reference Figure 3 and Figure 4 The linkage member 34 includes: a buffer sleeve 35, which is hollow inside, and the limiting column 31 is suitable for being inserted into the buffer sleeve 35; an adjusting block 36, which is symmetrically arranged on the outer wall of the buffer sleeve 35, and the adjusting block 36 is suitable for being inserted into the limiting groove 12. The side wall of the buffer sleeve 35 is symmetrically provided with two positioning grooves 37, one positioning groove 37 corresponds to one limiting block 32, and the limiting block 32 is suitable for being inserted into the positioning groove 37; when the limiting block 32 is inserted into the positioning groove 37, the limiting block 32 and the adjusting block 36 are located in the same horizontal plane, and the length of the limiting block 32 and the length of the adjusting block 36 are slightly smaller than the slot length of the limiting groove 12. The positioning groove 37 and the adjusting block 36 are staggered.

[0073] Reference Figure 7In order to facilitate the positioning of the limit block 32, the two side walls of the positioning groove 37 are respectively hinged with an adjustment bar 38, and the two adjustment bars 38 are arranged opposite to each other. The limit block 32 is suitable for squeezing the adjustment bars 38 to flip downward. Further, the two side walls of the positioning groove 37 are respectively provided with a damper 370, one damper 370 corresponds to one adjustment bar 38, and the damper 370 is suitable for abutting against the upper surface of the adjustment bar 38. When the limit block 32 moves downward and is inserted into the positioning groove 37, the limit block 32 is suitable for squeezing the two adjustment bars 38 to flip downward with the hinge point as the axis. When the limit block 32 moves upward from the bottom of the two adjustment bars 38, the adjustment bar 38 turns upward with the hinge point as the axis, and the upper surface of the adjustment bar 38 abuts against the damper 370, and the damper 370 is suitable for increasing the resistance of the adjustment bar 38 to turn upward. When the limit block 32 moves upward, it is suitable for driving the buffer sleeve 35 to move upward synchronously. At the same time, during the upward movement of the limit block 32, it drives the adjustment bar 38 to gradually squeeze the damper 370, so that the damper 370 gradually and slowly shrinks. After the limit block 32 is inserted into the positioning groove 37, the adjustment bar 38 is suitable for limiting the limit block 32, and when the limit column 31 moves upward, it is suitable for driving the buffer sleeve 35 to move upward synchronously.

[0074] Reference Figure 3 Furthermore, in order to mitigate the impact force when the floating insert 2 is assembled with the lower bottom mold 1, the stopper assembly 3 further includes two gaskets 39, the gaskets 39 are arc-shaped, and the two gaskets 39 are arranged opposite to each other. The gaskets 39 are flexible parts, and a through groove adapted to the stopper block 32 is provided between the two gaskets 39. When the buffer sleeve 35 moves upward, it is suitable for pushing the gasket 39.

[0075] The bottom wall of the floating insert 2 is provided with a groove matched with the gasket 39 , and the thickness of the gasket 39 is greater than the depth of the groove.

[0076] Reference Figure 3 When the floating insert 2 is assembled with the lower bottom mold 1, the gasket 39 plays a buffering role to prevent the floating insert 2 from directly colliding with the lower bottom mold 1. The floating insert 2 is pressed, and the gasket 39 is compressed until the bottom wall of the floating insert 2 abuts against the upper surface of the lower bottom mold 1. At this time, the limit column 31 rotates circumferentially, and the limit block 32 is suitable for being inserted into the limit groove 12.

[0078] The upper mold 4 has an injection hole 40 formed thereon;
