Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pipe socket and spigot molds, and particularly relates to an injection mold for processing pipe sockets and spigots. Background Technique
[0002] A pipe socket and spigot is a form of pipe connection, where one end of the pipe is directly inserted into the interface of the other end to achieve pipe connection. This connection method is usually used for small-diameter pipe connections and has advantages such as tight connection and good stability. Socket and spigot pipes are commonly used for transporting fluids such as chemical drugs, water, petroleum, and natural gas. Due to their high strength and excellent sealing performance, they can operate under high-pressure and high-temperature environments, withstand a certain amount of pressure and tensile force, and are widely used in various fields such as industry, construction, water conservancy, and environmental protection.
[0003] An injection mold for processing pipe sockets and spigots is a mold specifically used for producing pipe socket and spigot components. A pipe socket and spigot injection mold usually includes two parts: an upper mold and a lower mold, as well as internal structures such as a core mold, a socket joint, and a spigot joint. The upper mold and the lower mold fit tightly to form an injection space. The core mold is used to form the internal structure of the pipe, and the socket joint and the spigot joint are respectively arranged on both sides of the core mold to form the socket and spigot parts of the pipe. Through the injection process, plastic or other injectable materials are injected into the mold to form the required socket and spigot shapes and structures.
[0004] When blanking the forming mold, for traditional pipe sockets and spigots, due to the smooth outer wall, the blanking is very fast. However, when there are non-smooth or special deformations on the outer wall of the socket and spigot, it will indeed increase the difficulty of blanking. Therefore, those skilled in the art have provided an injection mold for processing pipe sockets and spigots to solve the problems raised in the above background technique.

[0024] The present utility model provides a technical solution, an injection mold for processing the socket and spigot of a pipeline. Please refer to Figures 1 to 5 , which includes a base 1. A fixed mold 6 is installed on the base 1. A moving mold 8 is arranged on one side of the fixed mold 6. A material injection port 7 is arranged on the side of the fixed mold 6 away from the moving mold 8. A slot 601 is opened on the side of the fixed mold 6 facing the moving mold 8. A clamping plate 9 is installed on the side of the moving mold 8 facing the slot 601. A mold cavity 12 is opened in the moving mold 8. A mold body 13 is arranged in the mold cavity 12. An inclined chute 11 is opened at the bottom side of the moving mold 8. A transverse chute 10 is opened inside the upper side of the moving mold 8. A limiting strip 15 is arranged in the transverse chute 10. One side of the limiting strip 15 is connected with a first hydraulic rod 14. A first vertical plate 3 is installed on the base 1. A second vertical plate 5 is arranged on the side of the first vertical plate 3 away from the moving mold 8. A second hydraulic rod 17 is installed on the second vertical plate 5. One end of the second hydraulic rod 17 facing the moving mold 8 is installed with a mold core 16.
[0025] The clamping plate 9 is inserted into the slot 601. One end of the clamping plate 9 is in contact with one end of the mold body 13. The moving mold 8 drives the clamping plate 9 to disengage from the fixed mold 6, so as to bring one end of the mold body 13 out of the fixed mold 6. The mold core 16 sequentially penetrates through the first vertical plate 3, the moving mold 8 and is inserted into the mold body 13 in the mold cavity 12. After the raw material is injected into the mold cavity 12 from the material injection port 7 at one end of the fixed mold 6 and the mold body 13 is formed, the second hydraulic rod 17 on the second vertical plate 5 drives the mold core 16 to contract, so that the mold core 16 disengages from the insertion with the mold body 13. One end of the first hydraulic rod 14 is fixedly installed with the first vertical plate 3. The limiting strip 15 is slidably inserted into the transverse chute 10. The inclined chute 11 is slidably inserted into the guiding inclined rod 4. When the inclined chute 11 at the bottom of the moving mold 8 is inserted into the guiding inclined rod 4, under the action of the guiding inclined rod 4, the moving mold 8 separates. A blanking chute 2 is opened on the base 1. At this time, the mold body 13 can fall out from the blanking chute 2 on the base 1, so as to complete the blanking of the mold body 13.
[0026] The injection mold for processing the socket and spigot of a pipeline in the present utility model is composed of a base 1, a fixed mold 6 and a moving mold 8. The fixed mold 6 is fixedly installed with the base 1. A first vertical plate 3 is installed on the base 1. One side at the bottom end of the first vertical plate 3 is installed with a guiding inclined rod 4. An inclined chute 11 is opened at the bottom side of the moving mold 8, and a transverse chute 10 is opened inside the upper side of the moving mold 8. A limiting strip 15 is arranged in the transverse chute 10. One side in the middle of the limiting strip 15 is installed with a first hydraulic rod 14, and the other end of the first hydraulic rod 14 is fixedly installed with the first vertical plate 3;
[0027] In the initial state, the fixed mold 6 is combined with the moving mold 8, and the moving mold 8 is divided into left and right parts. A mold cavity 12 is provided in the moving mold 8, and a mold core 16 is inserted into the mold cavity 12. After the raw material is injected into the mold cavity 12 from the injection port 7 at one end of the fixed mold 6, after the mold body 13 is formed, the second hydraulic rod 17 on the second vertical plate 5 drives the mold core 16 to contract, so that the mold core 16 is disengaged from the insertion connection with the mold body 13. Subsequently, the first hydraulic rod 14 on the first vertical plate 3 drives the limit strip 15 to contract, and the limit strip 15 drives the moving mold 8 to move. During the movement of the moving mold 8, when the inclined sliding groove 11 at the bottom of the moving mold 8 is not inserted into the guiding inclined rod 4, the moving mold 8 drives the buckle plate 9 to disengage from the fixed mold 6, so as to take out one end of the mold body 13 from the fixed mold 6. When the inclined sliding groove 11 at the bottom of the moving mold 8 is inserted into the guiding inclined rod 4, under the action of the guiding inclined rod 4, the moving mold 8 is separated, and at this time the mold body 13 can fall out from the blanking groove 2 on the base 1, thus completing the blanking of the mold body 13. This structure reduces the difficulty of blanking when there are non-smooth or special deformations on the outer wall of the socket.
