[0025] Embodiment 1:

[0026] A lost foam casting hammer head, comprising a hammer head casting box 1, a lifting mechanism 2 for facilitating the unloading of the hammer head is arranged on the inner side of the hammer head casting box 1, the lifting mechanism 2 comprises a hydraulic cylinder 201, an L-shaped lifting plate 202, a bottom plate 203 and a leakage groove 204, the hydraulic cylinder 201 is symmetrically arranged at the center of both sides of the hammer head casting box 1, and the output shaft end of the hydraulic cylinder 201 is connected and fixed to the top of the L-shaped lifting plate 202, the bottom of the L-shaped lifting plate 202 is fixedly installed on both sides of the bottom plate 203, the bottom plate 203 is arranged on the inner bottom of the hammer head casting box 1, and a plurality of leakage grooves 204 are equidistantly opened on the bottom plate 203, and the plurality of leakage grooves 204 are used for the falling of quartz sand inside the hammer head casting box 1;

[0027] In this embodiment, by arranging a lifting mechanism 2 inside the hammer casting box 1, the hammer head cooled and formed in the hammer casting box 1 can be lifted and exposed from the hammer casting box 1 without digging it out from the quartz sand, which facilitates the unloading of the hammer head and improves work efficiency. By synchronously driving the two hydraulic cylinders 201, the bottom plate 203 inside the hammer casting box 1 is lifted from the inner cavity. At this time, the hammer head cooled and formed on the bottom plate 203 is exposed as the bottom plate 203 is lifted. During the lifting process, the quartz sand above the bottom plate 203 falls into the inner cavity of the hammer casting box 1 through the leakage groove 204 for unified unloading and recovery.

[0028] Embodiment 2:

[0029] Based on Example 1, different from Example 1, a discharging mechanism for quartz sand is provided at the bottom of the hammer casting box 1, and the discharging mechanism includes a first discharging plate 3, a second discharging plate 4 and an opening and closing mechanism 5. The first discharging plate 3 and the second discharging plate 4 are symmetrically arranged at the bottom opening of the hammer casting box 1, and form a complete box space with the hammer casting box 1.

[0030] The opening and closing mechanism 5 includes a servo motor 501, a worm 502, a worm wheel 503, a forward and reverse screw rod 504 and a movable slider 505. The servo motor 501 is fixedly installed on both sides of the support frame 11 at the outer bottom end of the hammer head casting box 1, and the output shaft of the servo motor 501 is connected and fixed to the connecting end of the worm 502 through a coupling. The worm 502 is connected to the worm wheel 503 arranged at one end of the forward and reverse screw rod 504 by transmission. The two ends of the forward and reverse screw rod 504 are symmetrically arranged on the movable slider 505, and the movable slider 505 is arranged in the center of the inner bottom surface of the first blanking plate 3 and the second blanking plate 4.

[0031] In this embodiment, a discharging mechanism is provided to facilitate automatic unloading of the quartz sand in the hammer casting box 1 and its recycling. The opening and closing mechanism 5 is used to realize the mutual approach or distance between the first unloading plate 3 and the second unloading plate 4, and the opening and closing of the bottom opening of the hammer casting box 1 are realized, so as to realize the automatic unloading of the internal quartz sand into the collection box at the bottom. The servo motor 501 is used to drive the worm 502 to rotate, and the rotation of the worm 502 drives the worm wheel 503 at one end of the forward and reverse screw rods 504 to rotate, so that the two movable sliders 505 on the forward and reverse screw rods 504 drive the first unloading plate 3 and the second unloading plate 4 to move closer to or away from each other, thereby realizing automatic unloading and the bottom closure of the hammer casting box 1.

[0032] The movable slider 505 includes a nut slider 5051, a cross plate 5052 and a fixed plate 5053. The nut slider 5051 is threadedly connected to the forward and reverse screw rods 504, and the two sides of the nut slider 5051 are fixedly connected to the bottom of the fixed plate 5053 through the cross plate 5052. The fixed plate 5053 is fixedly installed in the center of the inner bottom surface of the first blanking plate 3 and the second blanking plate 4.

[0033] The forward and reverse screw rods 504 are arranged in the inner cavity of the protective plate 6, and the two ends of the forward and reverse screw rods 504 are rotatably connected to the side plates 8 on both sides of the protective plate 6. The side plates 8 are fixedly installed on the support frame 11. Through grooves 7 are opened on both sides of the inner cavity of the protective plate 6, and the through grooves 7 are slidably connected to the cross plate 5052.

[0034] By arranging the forward and reverse screw rods 504 in the inner cavity of the protective plate 6, the quartz sand particles on the upper quartz sand are prevented from remaining in the thread grooves on the forward and reverse screw rods 504 during the unloading process, thereby ensuring the normal operation of the device and avoiding blockage that affects work efficiency.

[0035] The top surfaces of the first blanking plate 3 and the second blanking plate 4 are slidably connected to the bottom surface of the hammer head casting box 1, and T-shaped slide rails 9 are provided on the top surfaces of both sides of the first blanking plate 3 and the second blanking plate 4. The T-shaped slide rails 9 are slidably connected to the T-shaped slide grooves 10 opened inside the bottom ends of both sides of the hammer head casting box 1, thereby improving the limiting support effect of the first blanking plate 3 and the second blanking plate 4.

[0036] By setting a T-shaped slide rail 9 and a T-shaped slide groove 10, the support stability of the first blanking plate 3 and the second blanking plate 4 is ensured, so that the T-shaped slide rail 9 slides in the T-shaped slide groove 10 during the movement of the first blanking plate 3 and the second blanking plate 4, thereby ensuring the stability of the movement and ensuring the stable support of the blanking plate.

[0037] The support frame 11 is arranged on the base frame 12, and the base frame 12 is used for the height-limiting support of the hammer casting box 1. The base frame 12 is arranged on the upper part of the quartz sand recovery box, and the quartz sand recovery box is used for recovering the quartz sand in the hammer casting box 1.

[0038] Working principle: First, inject some quartz sand into the inside of the hammer casting box 1, place the hammer model on the quartz sand, retain the pouring port, and then continue to inject quartz sand to completely bury the hammer model in the quartz sand, pour the raw material pouring liquid through the pouring port, wait for the lost foam to solidify and cool to form a casting, and after the hammer is cooled and formed, drive the hydraulic cylinder 201 to slowly raise the bottom plate 203 inside the hammer casting box 1. At the same time, the servo motor 501 drives the first unloading plate 3 and the second unloading plate 4 to move away from each other, and the opening at the bottom of the hammer casting box 1 is opened, and the quartz sand inside the hammer casting box 1 and on the bottom plate 203 automatically falls through the opening to the quartz sand collection box at the bottom. At this time, the lifting of the bottom plate 203 makes it convenient for the staff to take the formed hammer on it, which facilitates the unloading of the hammer and improves work efficiency.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
