[0019] In order to make the purpose and technical solution of the utility model clearly and completely described, and the advantages more clearly understood, the embodiments of the utility model are further described in detail in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are part of the embodiments of the utility model, not all of the embodiments, and are only used to explain the embodiments of the utility model, and are not used to limit the embodiments of the utility model. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] Embodiment 1
[0021] See also Figure 1 to Figure 2 The utility model provides a technical solution: a casting sand box for the production of machine tool crossbeam castings, including a box body 1, hammer grooves 4 are opened on both sides of the surface of the box body 1, the surface of the hammer groove 4 is rotatably connected with a rotating shaft 6, the bottom end of the rotating shaft 6 is fixedly connected with a hammer plate 5, and the surface of the rotating shaft 6 is slidably connected with a fixed plate 10. The hammer plate is installed on the rotating shaft on the surface of the sand box, and the required sand and soil can be knocked at any time. The structure is simple, convenient to store and use, and the rotating shaft can be used as a handle and a force point to carry and transport the sand box.
[0022] Embodiment 2
[0023] See also Figure 3 On the basis of the first embodiment, in order to realize that the hammer plate 5 knocks the box body 1, a plurality of slots 2 are provided on both sides of the interior of the box body 1, and the slots 2 are distributed in an array. The surfaces of the slots 2 are clamped with plug plates 3, and the hammer slots 4 are square slots. Rotary holes 12 are provided on both sides of the hammer slot 4, and the rotary holes 12 are square slots. The rotating shaft 6 is rotatably connected in the rotating holes 12, and a rubber block 7 is fixedly connected to the surface of the hammer slot 4, and the surface of the rotating shaft 6 is fixedly connected to the other end of the rubber block 7.
[0024] The rubber block 7 is fixedly connected between the hammer slot 4 and the rotating shaft 6 so that after the hammer plate 5 is rotated and lifted, the rubber block 7 is in a stretched state, so that the hammer plate 5 has traction when falling and has a stronger knock on the sand box.
[0025] Embodiment 3
[0026] See also Figure 4 On the basis of the second embodiment, in order to realize that the rotating shaft 6 can be fixed and no longer rotate and the hammer plate 5 will not produce error knocking, the rotating shaft 6 has a "T"-shaped circular plate structure in cross section, and two groups of slider grooves 8 are provided on the surface of the rotating shaft 6, each group of slider grooves 8 has two slider grooves, and the two groups of slider grooves 8 are symmetrically distributed. The surfaces of the slider grooves 8 are slidably connected with sliders 9, and the sliders 9 have a square block structure. The fixing plate 10 has a square plate structure. The surface of the fixing plate 10 has a fixing hole 11, and the fixing hole 11 is a circular hole. The slider 9 is fixedly connected to the surface of the fixing hole 11, and the hammer plate 5 has a block structure, and the hammer plate 5 is provided with an arc surface on the side close to the surface of the hammer groove 4.
[0027] A fixing plate 10 is slidably connected to the surface of the rotating shaft 6, and the fixing plate 10 is slid into the shaft hole 12 so that the rotating shaft no longer rotates. The rotating shaft can be used as a handle to carry the sand box and prevent the hammer plate from shaking when not in use and accidentally hitting the sand box.
[0028] In actual use, first insert the insert plate 3 into the appropriate slot 2 according to the size of the beam casting, then pour in engineering sand and rotate the hammer plate 5 by hand. After releasing the hand, the hammer plate 5 makes a circular motion to knock on the body 1 of the sand box. After multiple knocks, the sand in the sand box is evenly distributed and compacted, and then casting is carried out. When the beam casting is hardened and needs to be removed, turn over the sand box, and knock the body 1 with the hammer plate 5 to loosen the sand and make the beam casting easy to be taken out. When the body 1 needs to be moved after use, slide the fixing plates 10 at both ends. When the fixing plates 10 are slid to the shaft hole 12, the shaft 6 can no longer rotate, and the hammer plate 5 will not knock the sand box by mistake. The body 1 is moved by hand.
