The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limitations on the present invention. On the contrary, the embodiments of the present invention include all changes, modifications, and equivalents that fall within the spirit and connotation of the appended claims.

[0018] The following describes the mold manufacturing hole expanding device according to an embodiment of the utility model in conjunction with the accompanying drawings.

[0019] like Figure 1 and Figure 2 As shown, the mold manufacturing hole expanding device of the embodiment of the utility model may include a base plate 1, a hole expanding mechanism 2, a clamping mechanism 3, a matching mechanism 4 and two fastening mechanisms 5.

[0020] Among them, the reaming mechanism 2, the locking mechanism 3, the matching mechanism 4 and the two fastening mechanisms 5 are all arranged on the base plate 1. The base plate 1 is provided with a slide groove 11. The reaming mechanism 2 is installed on the slide groove 11. The locking mechanism 3 is installed on the matching mechanism 4. The locking mechanism 3 is installed between the two fastening mechanisms 5.

[0021] It should be noted that the engaging mechanism 3 is directly mounted on the matching mechanism 4 .

[0022] The engaging mechanism 3 may include a first connecting rod 31 , a second connecting rod 32 , a first pin shaft 33 , a moving tube 35 and two second pin shafts 34 .

[0023] Among them, the first connecting rod 31 is "L"-shaped, one end of the first connecting rod 31 is connected to the movable tube 35 on one side through the second pin shaft 34, one end of the second connecting rod 32 is connected to the first connecting rod 31 through the first pin shaft 33, and the other end of the second connecting rod 32 is connected to the movable tube 35 on the other side, and a groove 351 is opened on the surface of the movable tube 35.

[0024] It should be noted that the first connecting rod 31 and the second connecting rod 32 described in this embodiment are rotatably connected by the first pin 33, and the sizes of the first pin and the cylindrical groove 411 on the surface of the matching mechanism 4 match each other. The first connecting rod 31 and the second connecting tube are rotatably connected by the second pin and the moving tube 35 respectively.

[0025] Specifically, when it is necessary to expand the hole of the C-shaped mold, first, insert the two sides of the C-shaped mold into the groove 511 on the surface of the fixed block 51 and the groove 351 on the surface of the movable tube 35 in turn. Then, move the first connecting rod 31, and the first connecting rod 31 will press downward along the cylindrical groove 411, and at the same time push the second connecting rod 32. The first connecting rod 31 is at a right angle to the base plate 1 and the second connecting rod 32 is in a horizontal state.

[0026] At this time, the moving tubes 35 on both sides will press outwards relatively, and the grooves 351 on the surface of the moving tubes 35 close to the inner side walls of the first connecting rod 31 and the second connecting rod 32 will cooperate with the abutment blocks 52 to press the sides of the C-shaped mold, thereby keeping the ends of the C-shaped molds on both sides stable. Finally, the column 21 is moved on the slide groove 11 to an appropriate position to expand the surface of the C-shaped mold.

[0027] Therefore, by setting a suitable C-type mold fixture, the clamping stability and positioning accuracy of the workpiece can be improved, ensuring the precise fixation of the mold before hole expansion and reducing errors.

[0028] It should be noted that an electric slider is installed at the bottom of the column 21, and the column 21 is slidably connected to the slide groove 11 through the electric slider. The connection method between the electric slider and the slide groove 11 is a conventional technical means in the field and will not be described here.

[0029] In one embodiment of the present invention, Figure 1 As shown, the matching mechanism 4 may include a base 42 and two vertical plates 41 .

[0030] The base 42 is disposed between the two fastening mechanisms 5, and the two vertical plates 41 are disposed on the base 42. The vertical plates 41 are provided with a cylindrical groove 411. It should be noted that the dimensions of the cylindrical groove 411 and the first pin shaft 33 match each other.

[0031] In one embodiment of the present invention, Figure 2 As shown, the fastening mechanism 5 may include a fixing block 51 and a stop block 52 .

[0032] The fixing block 51 is sleeved on the moving tube 35 , a slot 511 is provided on the front of the fixing block 51 , the position of the slot 511 corresponds to the position of the strip groove 351 , and the stop block 52 is relatively arranged on the outside of the slot 511 .

[0033] It should be noted that the groove 351 described in this embodiment will move closer to the adjacent stopper 52 when the moving tube 35 moves, and the two C-shaped molds are abutted by the side of the groove 351 and the stopper 52 to ensure the stability of the mold.

[0034] In one embodiment of the present invention, Figure 1 As shown, the reaming mechanism 2 may include a column 21 and a reamer 22 .

[0035] The column 21 is slidably disposed on the slide slot 11 , and the reamer 22 is installed on the column 21 .

[0036] It should be noted that the reamer 22 described in this embodiment is a processing tool, which is mainly used to expand the diameter of an existing hole to achieve the required dimensional accuracy and surface finish. It is a prior art in this field and will not be described in detail here.

[0037] Specifically, when the relevant staff is expanding the hole of the mold, they can adjust the position of the reamer 22 by moving the column 21, and expand the hole at the corresponding position on the original hole of the mold.

[0038] In summary, the mold manufacturing reaming device of the embodiment of the utility model can improve the clamping stability and positioning accuracy of the workpiece by setting a clamp suitable for the C-shaped mold, ensure the precise fixation of the mold before reaming, and reduce errors.
