Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figures 1-6 As shown, this utility model is a casting mold for easy demolding of tractor steering knuckle casting, including a base 1 and four supports 2, the bottom of the four supports 2 being fixedly connected to the top of the base 1.
[0025] A demolding assembly 11 is provided above the base 1. The demolding assembly 11 includes a cover 111. Two bolts 112 are threadedly connected to the top of the cover 111. Molds 113 are threadedly connected to the bottom of both bolts 112. Handles 115 are fixedly connected to opposite sides of the two molds 113. Several positioning shafts 116 are fixedly connected to the back of the mold 113 on the front. Several positioning holes 161 are opened on the front of the mold 113 on the back. Limit seats 114 are inserted into the left and right sides of the mold 113. Bolts 117 are threadedly connected to the top of the limit seats 114. The bottom is threadedly connected to the inside of the mold 113. This utility model sets up a demolding component 11. Specifically, after cooling, the demolding operation is performed. First, turn the two bolts 112 to remove them from their fixed positions. Then, easily remove the cover 111. Next, turn the four bolts 117 to remove them as well. At this time, hold the handle 115 of the mold 113 and pull it forcefully to separate the two molds 113 smoothly. This step greatly facilitates demolding, reduces the consumption of time and labor costs, will not easily damage the product, and also improves demolding efficiency.
[0026] A vibration assembly 12 is provided below the demolding assembly 11. The vibration assembly 12 includes a vibration seat 121. The top of the vibration seat 121 is fixedly connected to the bottom of the limiting seat 114. Slide rods 122 are slidably connected inside the front and back of the vibration seat 121. The two supports 2 on the back and the two supports 2 on the front each form a group. The opposite side of a group of supports 2 is fixedly connected to the left and right sides of the slide rods 122. In this utility model, by setting the vibration assembly 12, the motor 126 drives the eccentric turntable 125 to rotate. The eccentric turntable 125 drives the reciprocating frame 124 to reciprocate along the path of the slide groove 242 through the round shaft. The reciprocating frame 124 drives the connecting frame 123 to reciprocate in the horizontal direction. The connecting frame 123 drives the vibration seat 121 to reciprocate in the horizontal direction. The vibration seat 121 drives the mold to reciprocate, thereby generating vibration, eliminating most of the air bubbles between the materials inside the mold 113, and improving the casting quality.
[0027] A connecting frame 123 is fixedly connected to the bottom of the vibration base 121, and a reciprocating frame 124 is fixedly connected to the bottom of the connecting frame 123. Limiting strips 241 are fixedly connected to the front and back of the reciprocating frame 124, and sliding grooves 242 are opened inside the front and back of the base 1.
[0028] The outer surface of the limiting strip 241 is slidably connected to the inner wall of the slide groove 242. The bottom of the reciprocating frame 124 is slidably connected to the eccentric turntable 125. The bottom of the eccentric turntable 125 is rotatably connected to the top of the base 1. A circular groove is opened at the bottom of the base 1. A motor 126 is fixedly connected to the inner wall of the circular groove. The top output end of the motor 126 is fixedly connected to the bottom of the eccentric turntable 125.
[0029] A specific application of this embodiment is as follows: First, the pre-prepared material is slowly poured into the feed pipe on the cover 111, ensuring that the material flows in without obstruction until the entire feed pipe is completely filled. At this time, attention should be paid to the filling status of the material to avoid overfilling or underfilling. Next, the motor 126 is started. The power output shaft of the motor 126 is connected to the eccentric turntable 125. When the motor 126 starts, the eccentric turntable 125 also begins to rotate. This rotation is cleverly converted into the reciprocating motion of the reciprocating frame 124 through the transmission of the circular shaft. The reciprocating frame 124 moves stably and precisely along the carefully designed slide groove 242. As the reciprocating frame 124 moves, the connecting frame 123 is also driven. The connecting frame 123 and the reciprocating frame 124 are tightly connected by a sturdy connector to ensure the effective transmission of force during the reciprocating motion. The connecting frame 123 reciprocates in the horizontal direction. The smooth and continuous motion trajectory provides a solid foundation for subsequent vibration. Next, the vibration seat 121 is driven by the connecting frame 123, also reciprocating in the horizontal direction. Vibration is crucial for eliminating most air bubbles between the materials inside the mold 113, significantly improving casting quality and ensuring the density and uniformity of the casting's internal structure. After sufficient vibration treatment, the mold begins to cool and solidify. Once cooling is complete, demolding is performed. First, two bolts 112 are loosened to remove them from their fixed positions. Then, the cover 111 is easily removed. Next, four bolts 117 are loosened and removed as well. At this point, the handle 115 of the mold 113 is grasped and pulled forcefully, allowing the two molds 113 to separate smoothly. This step greatly facilitates demolding, reduces time and labor costs, prevents damage to the product, and improves demolding efficiency.
