Description

Technical Field

[0001] The invention belongs to the technical field of hardware casting, in particular to a pipe joint casting device. Background Art

[0002] Pipe fitting casting is a part that connects pipes in hydraulic systems or installs pipes on hydraulic components. It is a general term for connectors that can be installed and removed in fluid passages, mainly including: welding type, ferrule type, crimping type and flaring type. Pipe fitting casting has a wide range of applications in the fields of cast iron and cast steel. During the casting process, the cast casting needs to be taken out of the mold cylinder, and then the inner surface of the large cylinder is cleaned, cooled and sprayed to ensure the normal subsequent pouring process. In addition, there are many types of existing hardware products, and many hardware products have strange shapes and many holes inside, so that when the hardware products are poured, a centrifuge is required to rotate the mold to evenly mix the solution inside the mold.

[0003] A Chinese patent with the announcement number CN104884190B discloses a centrifugal casting device, a mold support, which is fastened to a freely rotatable rotating worktable; and a mold, which is placed in the mold support and held, the mold support having: a bottomed cylindrical mold support body, which is formed of a metal material; a heat insulating component, which is arranged on the inner circumference and bottom surface of the mold support body; and a mold positioning component, the mold having: a mold body, which has a cavity for injecting molten metal and is formed of an oxide; and a mold table, which is arranged on the mold body and has a mold positioning component insertion hole that enables the mold positioning component to be inserted and engaged, and is formed of an oxide. In the existing centrifugal casting device, the following methods are used for installing the mold: a method of inserting the mold into a cylindrical tube arranged on the rotating worktable and filling the gap between the cylindrical tube and the mold with ceramic heat insulating materials, etc. to position and fix the mold; a method of using a belt or the like to bind and fix the mold to position and fix the mold on the rotating worktable.

[0004] In the current prior art, multiple hardware products are cast at one time inside the existing casting mold. After each casting, in order to ensure that the molten steel inside the mold can cover every corner inside the mold, a centrifuge is needed to centrifugally rotate the mold so that the molten steel can effectively adhere to the internal space of the mold. Since the molten steel inside the mold has not completely solidified after centrifugal rotation, a waiting time is required. During the waiting time, the centrifuge will be in a completely idle state. In order to increase the frequency of use of the centrifuge, the mold on the output end of the centrifuge needs to be replaced, and each movement of the mold requires an employee to install the fixing device on the output end of the centrifuge on the surface of the mold, so that the centrifuge and the mold are fixed together through the fixing device. During the entire process of use, the fixing device on the output end of the centrifuge needs to be manually disassembled, installed, and fixed repeatedly, which makes the overall process cumbersome, and time is wasted on disassembly and installation. The fixing device on the output end of the centrifuge cannot be quickly disassembled and installed on the surface of the mold, which leads to the problem of low work efficiency.

As the swing arm 138 continues to slide down, the inclined surface of the slide groove 122 is fitted with the inclined groove a5 on the outer surface of the swing arm 138, and the swing arm 138 is squeezed and pushed outward by the tilting angle of the buckle ring 121, so that the swing arm 138 is turned over and expanded outward, and then the swing arm 138 is used to push and compress one end of the elastic wire 136. As the swing arm 138 continues to descend, when the buckle ring 121 and the sunken groove a3 are at the same horizontal angle, the inner wall surface of the swing arm 138 Without the position restriction of the buckle ring 121, the elastic wire 136 on the outer surface of the swing arm 138 will push the swing arm 138 in the opposite direction, so that the sunken groove a3 on the outer surface of the swing arm 138 is sleeved onto the bottom outer surface of the buckle ring 121, and the swing arm 138 is lifted upward again by the hydraulic telescopic machine 115, so that the bottom surface of the buckle ring 121 and the surface of the undercut a4 are pushed together. When the surface of the casting mold 12 is completely clamped, the multiple swing arms 138 can clamp and restrict the outer surface of the casting mold 12 in multiple directions, and the effect of quickly installing and positioning the mold is achieved. The suspended casting mold 12 cooperates with the motor 13 to rotate the casting mold 12, and the centrifugal force generated when the casting mold 12 rotates is used to fill the molten steel inside the casting mold 12 into different corners inside the casting mold 12;

[0036] When the molten steel inside the casting mold 12 solidifies, the motor 13 is lowered with the hydraulic telescopic machine 115, so that the undercut a4 and the bottom surface of the slide groove 122 are relaxed. At this time, the triangular lower pressure plate 137 is driven to descend by the small hydraulic rod 133, and the outer surface of the triangular lower pressure plate 137 is attached to the surface of the lower slide groove a2. As the triangular lower pressure plate 137 continues to descend, the inclined surface of the triangular lower pressure plate 137 pushes the swing arm 138, so that the swing arm 138 swings toward the outside. The expansion makes the slide groove 122 fall out from the inside of the sunken groove a3, and then the swing arm 138 is driven to rise by the hydraulic telescopic machine 115, and the casting mold 12 is moved away under the rotation of the motor 2 14, so that the motor 13 clamps the top of another group of casting molds 12, and then the motor 13 is used to centrifugally rotate the casting mold 12 to achieve rapid replacement of multiple casting molds 12, and the centrifuge does not need to wait for the time of mold demoulding, film closing, and pouring molten steel, thereby increasing the effect of continuous processing of the mold.

[0037] Furthermore, if Figure 1 - Figure 8As shown, the outer surface of the swing arm 138 is symmetrically fixedly connected to the limit plate a1 at the edge positions on both sides of the sliding groove a2, the outer surface of the triangular lower pressure plate 137 is movably fitted on the outer surface of the sliding groove a2, the outer surface of the slide groove 122 is movably fitted on the outer surface of the inclined groove a5, and the outer surface of the motor 13 is fixedly connected with a mold sleeve ring 131 arranged on the outer surface of the top of the small hydraulic rod 133, the top surface of the triangular lower pressure plate 137 is fixedly connected with the limit rod 134 at the edge positions on both sides of the small hydraulic rod 133, and the outer surface of the limit rod 134 is movably sleeved on the outer surface of the docking sleeve 132, and a slide table 111 is provided on the other side surface of the processing table 11, and a plurality of groups of support rods 112 are fixedly connected on the top surface of the processing table 11, and two groups of support rods 112 are fixedly connected. A molten steel pouring device 113 is fixedly connected to one end of the support rod 112, a limiting ring 114 is fixedly connected to one end of the four groups of support rods 112, and a groove 116 is arranged between the bottom surface of the limiting ring 114 and the top surface of the processing table 11, a cavity is arranged between the inner wall surface of the processing table 11 and the outer surface of the limiting ring 114, the outer surface of the casting mold 12 is movably sleeved on the inner wall surface of the cavity, a support arm 141 movably sleeved inside the groove 116 is fixedly connected to the output end surface of the motor 14, a C-shaped ring claw 142 movably sleeved on the outer surface of the casting mold 12 is fixedly connected to one end of the support arm 141, a groove 143 is opened on the inner wall surface of the C-shaped ring claw 142, and an anti-slip strip 144 is arranged on the inner wall surface of the groove 143.

[0038] When the support arm 141, C-shaped collar claw 142, chute table 111, molten steel pouring device 113, limiting collar 114 and casting mold 12 provided by the present invention are used, the casting mold 12 is sleeved on the inner wall surface of the C-shaped collar claw 142, and the C-shaped collar claw 142 is used to wrap around the outer surface of the casting mold 12 to limit the position of the casting mold 12, and then the support arm 141 is rotated by the motor 2 14, so that the casting mold 12 moves inside the cavity between the limiting collar 114 and the processing table 11, and the molten steel pouring device 113 is used to pour molten steel into the interior of the casting mold 12. After the molten steel is poured, the motor 2 14 continues to rotate to drive the casting mold 12 in the chute The inside of the table 11 continues to move, causing the casting mold 12 to move to the bottom of the motor 13, so that the casting mold 12 and the motor 13 are at the same vertical angle, and the motor 13 cooperates to centrifugally rotate the casting mold 12, so that the molten steel inside the casting mold 12 is covered on the wall surfaces of different angles inside the casting mold 12. As the casting mold 12 continues to move in the future, the molten steel inside the casting mold 12 is naturally cooled and solidified. When the casting mold 12 moves to the entrance and exit of the chute table 111, the casting mold 12 is disassembled and replaced with a new casting mold 12, achieving the effects of continuous infusion of molten steel, centrifugal covering, cooling and solidification, and rapid disassembly of the casting mold 12;

[0039] The triangular pressing plate 137 is driven to descend by the small hydraulic rod 133, and the outer surface of the triangular pressing plate 137 is fitted with the surface of the sliding groove a2. When the triangular pressing plate 137 and the sliding groove a2 are fitted, the limiting plate a1 is used to limit the position of the two side surfaces of the triangular pressing plate 137, so that the triangular pressing plate 137 and the sliding groove a2 are directly fitted and contacted, and the thrust of the triangular pressing plate 137 is directly transmitted to the surface of the sliding groove a2, and the position of the triangular pressing plate 137 is limited.

[0040] The working principle provided by the present invention is as follows: the docking sleeve 132 is lowered in cooperation with the hydraulic telescopic machine 115, and the bottom surface of the docking sleeve 132 is sleeved on the top outer surface of the casting mold 12, and the inclined groove a5 on the inner bottom surface of the swing arm 138 is fitted on the surface of the slide groove 122. As the swing arm 138 continues to slide down, the inclined surface of the slide groove 122 is fitted with the inclined groove a5 on the outer surface of the swing arm 138, and the tilting angle of the buckle ring 121 is used to squeeze and push the swing arm 138 outward, so that the swing arm 138 is turned over and expanded outward, and then the swing arm 138 is used to push and compress one end of the elastic wire 136. As the swing arm 138 continues to descend, when the buckle ring 121 and the sunken groove a3 are at the same horizontal angle, the inner wall surface of the swing arm 138 is not The position of the buckle ring 121 is limited, and the elastic wire 136 on the outer surface of the swing arm 138 will push the swing arm 138 in the opposite direction, so that the sunken groove a3 on the outer surface of the swing arm 138 is sleeved onto the bottom outer surface of the buckle ring 121, and the swing arm 138 is lifted upward again by the hydraulic telescopic machine 115, so that the bottom surface of the buckle ring 121 and the surface of the undercut a4 are pushed together. When the surface of the casting mold 12 is completely clamped, the multiple swing arms 138 can clamp and limit the outer surface of the casting mold 12 in multiple directions. The suspended casting mold 12 cooperates with the motor 13 to rotate the casting mold 12, and the centrifugal force generated when the casting mold 12 rotates is used to fill the molten steel inside the casting mold 12 into different corners inside the casting mold 12;
