The main rod includes a first main rod 11, a second main rod 12, a third main rod 13, and a fourth main rod parallel to each other The main rod 14, the fifth main rod 15 and the sixth main rod 16, the connecting skeleton includes a first connecting skeleton 21, a second connecting skeleton 22, a third connecting skeleton 23, a fourth connecting skeleton 24, a fifth connecting skeleton 25, a The sixth connecting skeleton 26 , the seventh connecting skeleton 27 , the eighth connecting skeleton 28 , the ninth connecting skeleton 29 , the tenth connecting skeleton 210 , the eleventh connecting skeleton 211 and the twelfth connecting skeleton 212 . The projection of the main rod along the direction of the main rod is a right-angled trapezoid. The fourth main rod 14, the fifth main rod 15, and the sixth main rod 16 correspond to the short base of the projection. The first main rod 11, the second main rod 12, the second main rod The three main rods 13 correspond to the projected long base, the third main rod 13 and the sixth main rod 16 correspond to the right-angled endpoints of the right-angled trapezoid, the connecting skeleton is perpendicular to the main rod, and the connecting skeleton forms two identical right-angled trapezoids. The first connecting frame 21 and the eighth connecting frame 28 are fixedly connected with the first main rod 11 and the second main rod 12 respectively; the second connecting frame 22 and the ninth connecting frame 29 are respectively connected with the second main rod 12 and the third main rod The rod 13 is fixedly connected; the third connecting frame 23 and the seventh connecting frame 27 are fixedly connected to the first main rod 11 and the fourth main rod 14 respectively; the fourth connecting frame 24 and the twelfth connecting frame 212 are respectively connected to the fourth main rod 14. The fifth main rod 15 is fixedly connected; the fifth connecting frame 25 and the eleventh connecting frame 211 are respectively fixedly connected to the fifth main rod 15 and the sixth main rod 16; the sixth connecting frame 26 and the tenth connecting frame 210 are respectively It is fixedly connected with the third main rod 13 and the sixth main rod 16 .
本实施例采用直角梯形，与砂芯5外形轮廓保持一定的距离，避免碰穿砂芯5的表面。该芯骨结构以六根主杆为支撑，分为上下两部分，使砂芯5的重量均匀分担到六根主杆上，并由十二根连接骨架相连接，加大了该芯骨的承重力。从而芯骨该构设计合理，起重力足，吊装砂芯过程平稳，易于脱模，强度和刚性强，不易于损坏，可重复使用，降低铸造成本。In this embodiment, a right-angled trapezoid is adopted to keep a certain distance from the outline of the sand core 5 to avoid touching the surface of the sand core 5 . The core frame structure is supported by six main rods and is divided into upper and lower parts, so that the weight of the sand core 5 is evenly distributed to the six main rods, and is connected by twelve connecting frames, which increases the bearing capacity of the core frame. . Therefore, the mandrel structure has a reasonable design, enough lifting force, a smooth process of hoisting the sand core, easy demoulding, strong strength and rigidity, not easy to be damaged, and can be reused to reduce casting costs.
该芯骨还设六根辐条，包括第一辐条31、第二辐条32、第三辐条33、第四辐条34、第五辐条35和第六辐条36，辐条与所述连接骨架在同一个平面。第一辐条31、第四辐条34分别与第二主杆12、第四主杆14固定连接；第二辐条32、第五辐条35分别与第二主杆12、第五主杆15固定连接；第三辐条33、第六辐条36分别与第三主杆13、第五主杆15固定连接。The core frame also has six spokes, including a first spoke 31, a second spoke 32, a third spoke 33, a fourth spoke 34, a fifth spoke 35 and a sixth spoke 36, and the spokes are on the same plane as the connecting skeleton. The first spoke 31 and the fourth spoke 34 are respectively fixedly connected with the second main rod 12 and the fourth main rod 14; the second spoke 32 and the fifth spoke 35 are respectively fixedly connected with the second main rod 12 and the fifth main rod 15; The third spoke 33 and the sixth spoke 36 are fixedly connected with the third main rod 13 and the fifth main rod 15 respectively.
辐条增加芯骨的强度和刚性，能将拉力有效分散到辐条上，避免某处拉力过大导致芯骨损坏。Spokes increase the strength and rigidity of the core bone, which can effectively distribute the tension to the spokes, and avoid damage to the core bone due to excessive tension somewhere.
以上固定连接可以是螺接、铆接、焊接，本实施例采取了焊接，焊接的固定方式更为牢靠，使用时间更长。主杆、连接骨架和辐条均为钢管且设有排气孔，铸铁芯骨脆性大，容易损坏，使用铸铁芯骨成本比较高，钢管刚性强，不易损坏，可反复使用；排气孔与主杆、连接骨架和辐条中的排气管道相通，有利于铸造过程有气体排出，提高铸件质量。第四主杆、第五主杆和第六主杆底部分别设两个圆形凸台8，六个凸台8等高且组成一个长方形。从而方便芯骨的存放，防止芯骨的磨损。The above fixed connection can be screwed, riveted, or welded. In this embodiment, welding is adopted, and the fixing method of welding is more reliable and has a longer service life. The main rod, the connecting frame and the spokes are all steel pipes with vent holes. The cast iron core is brittle and easy to damage. The cost of using cast iron core is relatively high. The exhaust pipes in the rods, the connecting frame and the spokes are connected, which is beneficial to the gas discharge during the casting process and improves the quality of the castings. The bottoms of the fourth main rod, the fifth main rod and the sixth main rod are respectively provided with two circular bosses 8, and the six bosses 8 are of the same height and form a rectangle. Thereby, the storage of the core bone is facilitated, and the wear of the core bone is prevented.
如图2所示，第一主杆11和第三主杆13中间分别设一吊环板，吊环板4位于该主杆中心位置，通过焊接连接，能使芯骨的重心位于中心，有利于吊装平衡。As shown in Figure 2, a ring plate is respectively arranged between the first main rod 11 and the third main rod 13, and the ring plate 4 is located at the center of the main rod, connected by welding, so that the center of gravity of the core bone can be located at the center, which is beneficial to hoisting balance.
吊环板4形状为长方形，能有效增大焊接面积，增加抗拉强度，中心位置开设有起吊孔41，能方便起吊钩穿过吊装。The ring plate 4 is rectangular in shape, which can effectively increase the welding area and increase the tensile strength. The central position is provided with a lifting hole 41, which can facilitate the lifting hook to pass through the lifting.
使用时，如图5所示，首先将芯骨用绳索固定于两根固定杆上，将固定杆抬起置于砂芯模具6顶面，放平固定。芯骨就悬挂于模具内部相应位置。将自硬砂7填入砂芯模具6，直到填满为止。经过几个小时的自硬砂硬化，芯骨已经牢牢固定在自硬砂7内部，将固定杆拆除，拆除模具，使用起吊机即可吊起芯骨，砂芯5即被吊起。During use, as shown in Figure 5, at first the mandrel is fixed on two fixed rods with ropes, the fixed rods are lifted and placed on the top surface of the sand core mold 6, and fixed flat. The mandrel hangs at the corresponding position inside the mould. Fill the self-hardening sand 7 into the sand core mold 6 until it is full. After several hours of self-setting sand hardening, the mandrel has been firmly fixed inside the self-setting sand 7, the fixing rod is removed, the mold is removed, and the mandrel can be lifted with a hoist, and the sand core 5 is lifted.
上述说明是针对本发明较佳可行实施例的详细说明，但实施例并非用以限定本发明的专利申请范围，凡本发明所提示的技术精神下所完成的同等变化或修饰变更，均应属于本发明所涵盖专利范围。The above description is a detailed description of the preferred feasible embodiments of the present invention, but the embodiments are not used to limit the scope of the patent application of the present invention.
