DETAILED DESCRIPTION

[0022] The utility model is further described in detail below:

[0023] like Figures 1 to 5 As shown, the utility model provides an alloy plate hammer production mold, including a lower mold 1 and an upper mold 2. A base 3 is fixedly installed at the bottom of the lower mold 1, and an escape hole 4 communicating with the mold groove is opened inside the lower mold 1. A stripping component 5 is fixedly installed on the top of the base 3. The stripping component 5 penetrates the bottom of the lower mold 1 and is located in the mold groove.

[0024] By providing a stripping assembly 5 on a base 3 located at the bottom of the lower mold 1 and located inside the stripping hole 4, after the alloy plate hammer is cast and formed by closing the lower mold 1 and the upper mold 2, the stripping assembly 5 can be operated so that the part located inside the stripping hole 4 moves upward and extends into the mold groove in the lower mold 1 to push the alloy plate hammer fitted inside it upward to separate it from the mold groove, thereby facilitating the stripping work and reducing labor. At the same time, an external water pipe can be connected to the lower mold 1 to inject water into the lower mold 1 so that it flows outside the mold groove so that the heat of the alloy plate hammer in the mold groove is conducted to the water flow through the lower mold 1 for discharge for heat dissipation, thereby improving its heat dissipation effect, reducing the cooling time and improving efficiency.

[0025] like Figure 3 and Figure 4 As shown, the stripping assembly 5 includes a mounting shell 51, which is fixedly mounted on the top of the base 3, a threaded rod 52 is rotatably mounted inside the mounting shell 51, a worm gear 53 is fixedly mounted below the outside of the threaded rod 52, a rotating rod 54 located on one side of the threaded rod 52 is rotatably mounted inside the mounting shell 51, a worm 55 meshing with the worm gear 53 is fixedly connected to the rear end of the rotating rod 54, a handwheel 56 located outside the mounting shell 51 is fixedly connected to the front end of the rotating rod 54, a slide plate 57 is threadedly connected to the outside of the threaded rod 52, and a push rod 58 is fixedly connected to the top of the slide plate 57.

[0026] By rotating the hand wheel 56, the rotating rod 54 located in the mounting housing 51 is driven to rotate by the hand wheel 56, and the worm 55 is driven to rotate by the rotation of the rotating rod 54, and the threaded rod 52 connected thereto is synchronously driven to rotate by the rotation of the worm 55. The rotation of the threaded rod 52 drives the slide plate 57 connected to its external thread to move upward along the limiting groove 31, and the slide plate 57 moves upward to drive the push rod 58 to move upward from the escape hole 4 to push the alloy plate hammer located in the die groove of the lower mold 1 upward, so that it is out of the tightly fitted die groove for easy removal.

[0027] like Figure 5 As shown, a cooling channel 11 is provided inside the lower mold 1 , a water inlet pipe 12 and a water outlet pipe 13 connected to the cooling channel 11 are fixedly connected to the outside of the lower mold 1 , and a heat dissipation fin plate 14 is fixedly installed inside the cooling channel 11 .

[0028] An external water pipe is connected to the water inlet pipe 12, and water is injected into the cooling channel 11 through the water inlet pipe 12. The water flows into the cooling channel 11 and cooperates with the heat dissipation fins 14 on the outside of the mold groove in the lower mold 1 to exchange heat with the alloy plate hammer formed in the mold groove, so that the heat flows into the water in the cooling channel 11, and the heat is conducted by the water and discharged along the water outlet pipe 13 to carry away the heat of the lower mold 1, thereby accelerating the forming of the alloy plate hammer and improving efficiency.

[0029] like Figure 4 As shown, the ejector pin 58 is located inside the ejection hole 4 and fits in with the bottom of the inner mold groove of the lower mold 1 .

[0030] The push rod 58 is fitted into the mold groove in the lower mold 1 to move it upward, so as to lift up the alloy plate hammer in the mold groove to make it separate from the mold groove and facilitate demoulding and removal.

[0031] like Figure 3 As shown, a limiting groove 31 is provided on the inner side of the base 3 , and limiting sliders 59 are fixedly connected to the left and right sides of the slide plate 57 , and the limiting sliders 59 are slidably connected to the inside of the limiting groove 31 .

[0032] The limiting slider 59 slides in the limiting groove 31 to limit the sliding plate 57 .

[0033] like Figure 4 As shown, the ejector rod 58 is arranged in a "T" shape to fit the ejection hole 4.

[0034] The ejector rod 58 is arranged in a "T" shape to fit with the ejection hole 4, so that the ejector rod 58 is closely attached to the inside of the ejection hole 4 and the bottom of the inner mold groove of the lower mold 1 to ensure tightness.

[0036] The heat dissipation fins 14 are equidistantly arranged above and below the water and the lower mold 1 to contact and conduct heat, thereby improving the heat dissipation effect of the lower mold 1.

[0037] The water inlet pipe 12 is arranged above the front side of the lower mold 1 , and the water outlet pipe 13 is arranged behind the bottom of the lower mold 1 .

[0038] Water enters the cooling channel 11 through the water inlet pipe 12 located above the front side of the lower mold 1 and is discharged from the water outlet pipe 13 at the rear bottom of the lower mold 1 to take away the heat, thereby improving the heat dissipation efficiency.

[0039] The following is a detailed description of the working principle of the alloy plate hammer production mold.

[0040] like Figures 1 to 5 As shown, the upper mold 2 and the lower mold 1 are connected and fixed with bolts, and the material is poured into the mold groove from the pouring port set on the upper mold 2, and the water pipe is connected to the water inlet pipe 12, and water is poured into the interior of the cooling channel 11 through the water pipe through the water inlet pipe 12, and the water flows into the cooling channel 11 and is located outside the mold groove of the lower mold 1. The heat exchange is carried out with the heat dissipation fin plate 14 and the alloy plate hammer formed in the mold groove, so that the heat flows to the water in the cooling channel 11, and the heat is conducted by the water and discharged along the water outlet pipe 13 to carry away the heat of the lower mold 1, thereby accelerating the forming of the alloy plate hammer, and waiting for the heat to flow to the water in the cooling channel 11. After the alloy plate hammer is cooled, the upper mold 2 is opened and disassembled, and the hand wheel 56 is turned to drive the rotating rod 54 in the mounting shell 51 to rotate, and the worm 55 is driven to rotate by the rotation of the rotating rod 54, and the threaded rod 52 connected thereto is synchronously driven to rotate by the rotation of the worm 55. The rotation of the threaded rod 52 drives the slide plate 57 connected to its external thread to move upward along the limiting groove 31, and the slide plate 57 moves upward to drive the push rod 58 to move upward from the escape hole 4 to push the alloy plate hammer in the die groove of the lower mold 1 upward, so that it can be separated from the tightly fitting die groove for easy removal.
