For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components; and they can refer to a wireless connection or a wired connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0032] This utility model embodiment provides an inlaid molding hammer, comprising:

[0033] Hammer body 1 extends along the length direction A. The hammer body 1 includes a handle section 11 and an assembly section 12. The handle section 11 and the assembly section 12 are fixedly connected. The assembly section 12 has an assembly hole 12a at one end away from the handle section 11.

[0034] Insert 2 is fixedly connected to the assembly section 12 of the hammer body 1. Part of the insert 2 is disposed in the assembly hole 12a, and another part of the insert 2 is disposed outside the assembly hole 12a. The insert 2 is interference-fitted with the assembly hole 12a.

[0035] In a specific embodiment, such as Figure 1 and Figure 2As shown, the hammer body 1 extends in the left-right direction. The left section of the hammer body 1 is the grip section 11, and the right section is the assembly section 12 with the assembly hole 12a. The left section of the insert 2 is inserted into the assembly hole 12a, and the right end is outside the hammer body 1. When the insert 2 is worn or deformed, only the insert 2 needs to be replaced, and the hammer body 1 can be reused, thereby reducing the cost of the molding hammer. The insert 2 is interference-fitted with the assembly hole 12a, so the insert 2 is not easy to fall off when striking the mold, thus improving the safety of the embedded molding hammer.

[0036] Furthermore, the hammer body 1 is made of steel;

[0037] And / or, the insert 2 is made of copper. Furthermore, the hammer body 1 is made of H13 steel, which does not require quenching treatment, has good strength and hardness, good wear resistance, and is not easy to break. The insert 2 is made of copper, which is easy to process.

[0038] The dimensions of the hammer body 1 and the insert 2 described in this application can be adaptively adjusted according to actual needs. In a specific embodiment, the length of the handle section 11 in the hammer body 1 is greater than the length of the assembly section 12; the length of the handle section 11 in the hammer body 1 is 168-172 mm, and / or the length of the assembly section 12 is 42-48 mm. This structure utilizes the lever principle, making it more labor-saving during use, thereby reducing the workload of workers and lowering labor costs.

[0039] The shapes of the grip section 11 and the assembly section 12 of the hammer body 1 can also be adjusted. For example, the grip section 11 can be a cuboid or a prism, and the assembly section 12 can be a cuboid or a prism. The shapes of the grip section 11 and the assembly section 12 can be the same or different. In one specific embodiment, the grip section 11 is cylindrical, and the diameter of the grip section 11 is 42-48 mm.

[0040] And / or, the assembly section 12 is cylindrical, and the diameter of the assembly section 12 is 68-72 mm.

[0041] Furthermore, the hammer body 1 also includes a transition section 13, one end of which is fixedly connected to the grip section 11, and the other end of which is fixedly connected to one end of the assembly section 12. The length of the transition section 13 is 18-22mm. This structural design makes the inlaid hammer easier to process.

[0042] Furthermore, the transition section 13 has a chamfer at one end near the grip section, and the chamfer R ranges from 48 to 52.

[0043] Furthermore, in the assembly section 12, the length of the assembly hole 12a is 25-35 mm;

[0044] And / or, the diameter of the mounting hole 12a is 32 to 38 mm.

[0045] Furthermore, the insert 2 includes an mounting section 21 and a striking section 22;

[0046] The mounting section 21 is disposed in the mounting hole 12a and is interference-fitted with the mounting hole 12a;

[0047] The striking section 22 is located outside the assembly hole 12a, and the striking section 22 is used to strike the mold.

[0048] Furthermore, the length of the mounting section 21 is greater than the length of the striking section 22;

[0049] The length of the mounting section 21 is 28-32 mm, and / or the length of the striking section 22 is 22-27 mm.

[0050] like Figure 2 As shown, the left section of the insert 2 is located in the mounting hole 12a, and the right section is located outside the hammer body 1. The mounting section 21 at the left end is longer than the striking section 22 at the right end, which can ensure the stability of the insert 2 when striking and improve the safety of using the inlaid hammer.

[0051] Furthermore, the diameter of the striking section 22 is larger than the diameter of the mounting section 21;

[0052] The diameter of the striking section 22 is 58-62 mm, and / or the diameter of the mounting section 21 is 32-38 mm, thereby forming a step between the striking section 22 and the mounting section 21, which facilitates the quick installation of the insert 2 on the hammer body 1 and improves the installation efficiency of the insert 2.

[0053] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to examples, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
