[0002] When precast concrete elbow pipe fittings are produced, they need to be cast and formed using an elbow casting structure. The elbow casting structure is also called a precast elbow casting mold. It is a mold used to produce curved concrete precast parts. It is a type of cement product mold. This structure is specially used to produce curved concrete precast parts. The design principle of the precast elbow casting mold mainly involves the selection of bending angle and radius, the selection of pipe materials, the mold structure and support method, and the required processing technology. These factors together determine that the mold can produce elbow shapes that meet specific requirements. The common elbow casting structure on the market is prone to gaps after the molding mold structure is close together, which can easily lead to liquid outflow, and when pouring, it is necessary to knock and vibrate the molding mold structure to compact the concrete, which is more cumbersome.

The pulling structure 208 is slidably installed on the structure 206 and the guide rod structure 207. The outer end of the pulling structure 208 is provided with a pulling rod. The inner bottom of the pulling structure 208 is an inclined structure. The side of the right forming mold structure 2 is welded and fixed with a force block 205 of a triangular structure. The top of the force block 205 is in sliding contact with the inner bottom of the pulling structure 208, so that the spring continuously pushes the pulling structure 208 to move downward, so that the bottom of the pulling structure 208 is in sliding contact with the top of the force block 205. Since the contact surface is an inclined structure, a force is generated to pull the two forming mold structures 2, so that the two forming mold structures 2 are continuously forced together, thereby improving the sealing effect and preventing concrete and liquid from being discharged through the gap.

[0025] In the embodiment of the present disclosure, Figure 3 and Figure 4 As shown, a connector assembly 101 with external threads is welded and fixed at the middle position of the top of the structural body 1, which is used to conveniently fix the inner mold assembly 104. Two support plate assemblies 102 are welded and fixed on the side of the structural body 1. The support plate assembly 102 is located on the outside of the forming mold structure 2; two guide plate assemblies 103 are welded and fixed between the two support plate assemblies 102. The guide plate assembly 103 is inserted into the interior of the two forming mold structures 2 to guide the movement of the two forming mold structures 2 and position them together. The tail of the impact head assembly 107 is welded and fixed with an L-shaped pull plate. 108, the pull plate 108 pulls the impact head assembly 107 and the auxiliary plate 106 to tilt, and the tilt of the auxiliary plate 106 is conveniently controlled by the pull plate 108; the connecting head assembly 101 is fixed with the inner mold assembly 104 by threads, and the top of the inner mold assembly 104 is installed with the flip assembly 105 through a rotating shaft. The top of the side of the flip assembly 105 is provided with a rotating shaft. The flip assembly 105 is a structure that can be flipped upward freely. The flip assembly 105 and the inner mold assembly 104 form a bending rod, so that the flip assembly 105 can be freely flipped with the help of the rotating shaft, and can be conveniently detached from the inside of the bent pipe after forming.

[0026] In the embodiment of the present disclosure, Figure 5 and Figure 6As shown, the side of the forming mold structure 2 is provided with an impact groove 201, and the inner end of the impact head assembly 107 is inside the impact groove 201, which transmits the impact force to quickly compact and solidify the concrete. The interior of the forming mold structure 2 is provided with an inner groove 202. After the two forming mold structures 2 are put together, the inner mold assembly 104 and the flip assembly 105 are inside the inner groove 202 to form a bend forming space; the top of the forming mold structure 2 is provided with a feeding port 203, and the bottom end of the feeding port 203 is connected to the inside of the inner groove 202, so that concrete can be added. The top of the forming mold structure 2 is welded with a guide with a funnel-shaped structure. The material structure 204 and the bottom end of the material guide structure 204 are connected to the feeding port 203 to control the concrete guiding flow; the outer plate structure 206 is welded and fixed to the side of the left forming mold structure 2, and the outer plate structure 206 is embedded in the side of the pulling structure 208. The side of the left forming mold structure 2 is welded with a guide rod structure 207, and the guide rod structure 207 is inserted into the interior of the pulling structure 208 to guide the sliding use of the pulling structure 208. The outside of the guide rod structure 207 is sheathed with a spring, and the bottom of the spring is in contact with the top of the pulling structure 208, and continuously pushes the pulling structure 208 to move downward, generating a continuous downward pressure force.

[0027] The working principle of this embodiment is as follows: when it is necessary to control the casting of the elbow, first control the structure body 1 to be fixed, then control the installation of the inner mold assembly 104, so that the inner mold assembly 104 is connected to the connector assembly 101 through a thread, then control the pulling structure 208 to rise, compress the spring outside the guide rod structure 207, and then control the two forming mold structures 2 to move towards each other and close together, and then stop manipulating the pulling structure 208, so that the spring continues to push the pulling structure 208 to move downward, so that the bottom of the pulling structure 208 slides into contact with the top of the force block 205. Since the contact surface is an inclined structure, it generates a pulling force. The force of the forming mold structure 2 is tightened to avoid gaps between the forming mold structures 2, which would cause the concrete and liquid to be discharged. Then, the concrete is controlled to be added to the inside of the material guide structure 204, so that the concrete enters the inside of the inner groove 202 through the feeding port 203 to form the bend. Then, the pulling plate 108 is pulled to cause the pulling plate 108 to drive the impact head assembly 107 and the auxiliary plate 106 to tilt. Then, the pulling is stopped to cause the impact head assembly 107 to contact the impact groove 201, generating an impact force and transmitting the vibration force to the forming mold structure 2, so that the concrete is quickly compacted after being vibrated, thereby improving the efficiency of the bend forming.
