[0030] Example 1:

[0031] like Figure 1 and Figure 2As shown, an auxiliary runner cleaning mechanism includes a cylinder fixing plate 102 and a connecting plate 107. The cylinder fixing plate 102 is connected to the lifting mechanism 200. The connecting plate 107 is located below the cylinder fixing plate 102. The connecting plate 107 and the cylinder fixing plate 102 are connected by a pull rod 110. In this embodiment, the cylinder fixing plate 102 and the connecting plate 107 are both plate-shaped, and both ends of the pull rod 110 are threaded rods. Furthermore, the four corners of the connecting plate 107 and the cylinder connecting plate 107 are connected by the pull rod 110 and then locked with a locking nut. Thereby ensuring the stability of the spacing between the connecting plate 107 and the cylinder fixing plate 102. In this embodiment, the telescopic oil cylinder 101 is installed on the cylinder fixing plate 102. The top wheel 103 is installed on the telescopic shaft of the telescopic oil cylinder 101 through the oil cylinder connecting seat 114. When the telescopic shaft of the telescopic oil cylinder 101 moves downward, the top wheel 103 moves downward, and when the telescopic shaft of the telescopic oil cylinder 101 moves upward, the top wheel 103 moves upward. Side fixed hole plates 104 are installed on the front and rear side walls of the oil cylinder connecting seat 114. The left and right ends of the fixed hole plates 104 on both sides are connected by the balancing roller shaft 106. A sliding cavity is formed between the top wheel 103 and the balancing roller shaft 106. Therefore, in this embodiment, the relative positions of the top wheel 103, the side fixed hole plate 104 and the balancing roller shaft 106 are fixed. Preferably, the top of the oil cylinder connecting seat 114 is provided with a threaded sleeve threadedly connected to the telescopic shaft, and the bottom of the oil cylinder connecting seat 114 is provided with a horn fork. The center of the top wheel 103 is equipped with a rotating shaft 105, and the rotating shaft 105 is rotatably mounted on the horn fork. Therefore, when the top wheel 103 is installed in the horn fork, the top wheel 103 can rotate relative to the oil cylinder connecting seat 114, and when the horn fork is rotated, the top wheel 103 can rotate relative to the oil cylinder connecting seat 114. A mounting plane is provided on the outer side wall of the angle fork, and the side fixing hole plate 104 is detachably mounted on the corresponding mounting plane by screws. Of course, in order to facilitate the installation of the rotating shaft 105, a through hole is provided on the side fixing hole plate 104 to facilitate the installation of the rotating shaft 105. Furthermore, the left and right sides of the side fixing hole plate 104 are downwardly inclined mounting arms, and the balancing roller shaft 106 can be installed at the end of the mounting arm. When the balancing roller shaft 106 is installed, the axis center of the two balancing roller shafts 106 and the axis center of the rotating shaft 105 form an isosceles triangle distribution, and the vertex angle is an obtuse angle.

[0032] In this embodiment, if Figure 1 and Figure 2As shown, two hinged plates 112 are installed on the connecting plate 107 at intervals. A movable cavity 115 is formed between the two hinged plates 112, and the movable cavity 115 passes through the connecting plate 107. The movable clamp arms 109 are hinged in pairs in the movable cavity 115, and the hinge shafts 113 of the movable clamp arms 109 are installed on the two hinged plates 112 along the front-to-back direction. When the top wheel 103 moves downward, the top wheel 103 causes the movable clamp arms 109 to rotate around the hinge shafts 113, thereby causing the movable clamp arms 109 to clamp the auxiliary runner. Finally, the auxiliary runner is broken under the action of shear force, completing the cleaning of the auxiliary runner. Further, as shown Figure 3 As shown, the movable clamp arm 109 includes a hinge portion 122, which is hinged to the corresponding hinge shaft 113. The top of the hinge portion 122 is provided with an outward-stretched force arm 121, the inner side wall of the force arm 121 is in rolling contact with the top wheel 103, and the outer side wall of the force arm 121 is in rolling contact with the corresponding balance roller shaft 106. In this embodiment, the inner side wall of the force arm 121 is an inclined surface with an inclination angle of 15°, so that it is restricted from sliding in the sliding cavity. The bottom of the hinge portion 122 is also provided with an outward-stretched clamp portion 123, and a jaw 124 is formed between the two clamp portions 123. When the top wheel 103 descends, the two clamp portions 123 move closer to each other and the jaw 124 contracts. That is, during the downward process of the top wheel 103, the top wheel 103 presses the inner side wall of the force arm 121, so that the distance between the two force arms 121 is widened, thereby making the movable clamp arm 109 9 rotates, thereby making the two clamp parts 123 move closer to each other, thereby applying shear force to the auxiliary runner, thereby completing the cleaning of the auxiliary runner, and during the downward process of the top wheel 103, the inner side wall of the force arm 121 rolls in contact with the top wheel 103, and the outer side wall of the force arm 121 rolls in contact with the corresponding balancing roller shaft 106, thereby making the force of the two force arms 121 balanced, thereby ensuring the stability of the force applied by the clamp parts 123 to the auxiliary runner, and when the top wheel 103 goes up, the balancing roller shaft 106 will apply external force to the force arm 121, causing the force arm 121 to rotate in the opposite direction, thereby resetting the movable clamp arm 109, and when in use, through the inclined plane pressurization and lever principle, the simple linear motion is converted into relative motion, and a 30-ton high-pressure oil cylinder with a small volume can be converted into a 60-ton clamping force, thereby clamping off the auxiliary runner, achieving the purpose of cleaning.

[0033] In this embodiment, if Figure 3As shown, the inner side wall of the clamp 123 has a flat surface. When the telescopic cylinder 101 is in the initial position, the flat surface is vertically arranged, so that the clamp 123 can better clamp the auxiliary runner. In this embodiment, the width of the jaw 124 can be controlled in advance according to the number of auxiliary runners. Usually, there are 8 or 12 auxiliary runners, and they are evenly distributed on the same circumference. Therefore, the width of the jaw 124 can be adjusted according to the number of auxiliary runners. That is, when the telescopic cylinder 101 is in the initial position, the top wheel 103 is in the upper stroke. When the jaws 124 are used, the flat surface is vertically arranged, and the width of the jaws 124 is slightly larger than the spacing between the parts clamped by the adjacent auxiliary runners. When in use, the adjacent auxiliary runners are located in the jaws 124 through the lifting mechanism 200, and then the telescopic cylinder 101 works, the top wheel 103 descends, and then clamps the auxiliary runner and applies shear force to the auxiliary runner, so that the auxiliary runner is cut off. Since the auxiliary runner is only subjected to shear force, the incision of the auxiliary runner is relatively smooth after cleaning, thereby avoiding deformation, stress and micro-cracks of the casting.

[0034] In this embodiment, if Figure 1 and Figure 2 As shown, end plates 108 extending vertically downward are further provided at the bottom of the left and right ends of the connecting plate 107. The end plates 108 can limit the range of motion of the movable clamp arm 109 to a certain extent, especially when the top wheel 103 moves to the upper stroke. At this time, the end plates 108 can abut against the clamp portion 123 to prevent the clamp portion 123 from continuing to rotate, thereby preventing the force arm 121 from escaping from the sliding cavity, thereby ensuring the reliability of the auxiliary runner clamping mechanism.

[0035] In this embodiment, if Figure 4 As shown, a limiting groove 125 is provided on the balancing roller shaft 106, and the outer wall of the lever arm 121 is stuck in the limiting groove 125. Furthermore, the width of the lever arm 121, the thickness of the top wheel 103 and the width of the limiting groove 125 are consistent. Therefore, when the outer wall of the lever arm 121 is stuck in the limiting groove 125, the lever arm 121 will not move axially after moving in the movable cavity 115, thereby further ensuring the reliability of the auxiliary runner clamping mechanism.

[0036] In this embodiment, if Figure 5As shown, the telescopic oil cylinder 101 drives the top wheel 103 downward, and the two clamp parts 123 move closer to each other and the jaws 124 contract. That is, during the downward movement of the top wheel 103, the top wheel 103 presses the inner side wall of the lever arm 121, and the inner side wall of the lever arm 121 is a 15° inclined surface. As the top wheel 103 descends, the distance between the two lever arms 121 is widened, thereby causing the movable clamp arm 109 to rotate, and then the two clamp parts 123 move closer to each other, thereby applying a shear force to the auxiliary runner, thereby completing the cleaning of the auxiliary runner. In addition, through the inclined surface pressure increase between the top wheel 103 and the lever 121 and the lever formed by the movable embedded arm, the simple vertical downward movement is converted into a relative movement, and the pressure increase effect is achieved. Therefore, while ensuring that the auxiliary runner can be cut off, the high-pressure oil cylinder with a smaller pressure can be rotated. In this embodiment, a 30-ton high-pressure oil cylinder with a small volume can be converted into a 60-ton clamping force, thereby clamping off the auxiliary runner and achieving the purpose of cleaning.

In this embodiment, the auxiliary runner cleaning mechanism 100 adopts the auxiliary runner mechanism of Example 1.

[0039] In this embodiment, if Figure 6As shown, the lifting mechanism 200 includes a lifting cylinder 201, which is mounted on a stand 500. A fixed pulley 203 is also mounted on the top of the stand 500. A movable pulley 202 is mounted on the execution end of the lifting cylinder 201.

The front end of the horizontal lifting frame 205 is mounted with a mounting frame 207 through a connecting seat 206. The cylinder fixing plate 102 of the auxiliary runner cleaning mechanism 100 is mounted on the mounting frame 207, and the cylinder fixing plate 102 of the auxiliary runner cleaning mechanism 100 is mounted on the mounting frame 207. When the lifting cylinder 201 is extended or retracted, it can be moved through the movable pulley 202, The fixed pulley 203 and the sliding chain 204 drive the horizontal lifting frame 205 to rise and fall. Furthermore, vertical guide rails 208 are arranged in pairs on the vertical frame 500, and a sliding seat 209 is provided at the rear end of the horizontal lifting frame 205. The sliding seat 209 slides on the vertical guide rail 208. During the initial installation, the horizontal lifting frame 205 is installed horizontally. After the horizontal lifting frame 205 is raised and lowered, the horizontality of the horizontal frame can also be guaranteed through the cooperation of the sliding seat 209 and the vertical guide rail 208. In this embodiment, the top of the connecting seat 206 is set to a screw rod, and a through hole matching the screw rod is opened on the horizontal lifting frame 205. The screw rod is locked with a locking nut after passing through the through hole, and the bottom of the connecting seat 206 is welded to the mounting frame 207, and the cylinder fixing plate 102 and the mounting frame 207 are detachably connected by screws.

Therefore, when the product shell mold is placed on the workbench, the product shell mold can be positioned by the positioning frame 600, thereby facilitating the auxiliary runner clamping mechanism to clean the auxiliary runner of the mold.
