Description

Technical Field

[0001] The utility model relates to the technical field of pipeline processing, in particular to a mold for processing anti-corrosion and heat-insulating pipelines. Background Art

[0002] A pipeline is a device connected by pipes, pipe connectors and valves for transporting gas, liquid or fluid with solid particles. With the development of industrialization, the market demand for anti-corrosion and thermal insulation pipelines is becoming increasingly strong. In the production process of anti-corrosion and thermal insulation pipelines, molds are often used to shape the pipelines.

[0003] The Chinese utility model patent with announcement number CN221872803U discloses a heat-insulating pipe forming mold, which includes a support seat, two sides of the support seat are connected with positioning plates, and the inner wall of the positioning plate is connected with a clamping assembly; the clamping assembly includes an electric telescopic rod, a clamp, a connecting frame, bolts and anti-slip teeth, the inner wall of the positioning plate is connected with the electric telescopic rod, and the inner wall of the electric telescopic rod is provided with a clamp, the middle part of the clamp is inserted with a connecting frame, the middle part of the clamp and the connecting frame are penetrated with bolts, and the inner surface of the clamp is provided with anti-slip teeth; the middle part of the clamping assembly is provided with a lower mold; and the upper end of the lower mold is provided with an upper mold, and the clamp and the connecting frame are driven to move inward by turning on the electric telescopic rod. By moving, the two sets of clamps can be moved closer to the lower mold and the upper mold, and the lower mold and the upper mold are positioned and locked by the clamps, which greatly improves the stability of the clamps on the lower mold and the upper mold. Although the above device improves the stability of the clamps on the lower mold and the upper mold, in actual use, since the device does not have a demoulding mechanism, when the pipe is formed, it is often necessary to manually demould the pipe. Since the pipe is often very tightly fitted to the mold after formation, the demoulding process is very time-consuming and labor-intensive, which reduces the production efficiency of the pipe. If demoulding equipment is used for demoulding, the production cost will be increased, and the demoulding equipment still needs to be operated manually, and the mold opening and demoulding cannot be carried out at the same time, resulting in a waste of time.

[0004] Therefore, it is urgent to provide a mold for processing anti-corrosion and thermal insulation pipes to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the above-mentioned prior art and provide a mold for processing anti-corrosion and heat-insulating pipelines.

[0006] In order to solve the above technical problems, the present invention adopts a technical solution: providing a mold for processing anti-corrosion and thermal insulation pipes, comprising a base and a lower mold, wherein the lower mold is fixed to the top of the base, and the inner mold is fixed to the inner side of the lower mold, an annular groove is formed on one inner wall of the lower mold, and a demoulding mechanism is provided on the outer wall of the lower mold on the side close to the annular groove;

[0007] A lifting mechanism is provided at the rear end of the base, and an upper mold is provided on the inner side of the lifting mechanism;

[0008] A pressing arm mechanism is fixed to one end of the upper mold, a liquid injection interface is provided on one side of the top of the upper mold, an exhaust port is provided on the other side of the top of the upper mold, and a cooling mechanism is provided inside the upper mold.

[0009] The utility model is further configured as follows: the lifting mechanism includes a slide groove fixed to the rear end of the base, and a top plate is fixed on the top of the slide groove, and a telescopic bar is installed on the top of the top plate.

[0010] Through the above technical solution, the rear end of the upper mold is slidably connected with the slide groove, and the upper mold is fixedly installed on the telescopic end of the telescopic rod. The telescopic rod can drive the upper mold to move up and down, so that the upper mold and the lower mold produce relative movement to achieve mold closing and opening. The slide groove can limit the upper mold to ensure the accuracy of mold closing.

[0011] The utility model is further configured as follows: the pressure arm mechanism includes a fixing seat installed on one end of the upper mold, and a connecting arm is fixed on the fixing seat, and a wedge block 1 is installed at the bottom end of the connecting arm.

[0012] Through the above technical solution, the upper and lower ends of one side of wedge block 1 are both inclined, and the upper mold can drive the fixed seat, connecting arm and wedge block 1 to move up and down. When wedge block 1 moves up and down, it can press the demoulding mechanism to perform demoulding.

[0013] The utility model is further configured as follows: the demoulding mechanism includes a sliding rod slidably arranged on one side of the inner wall of the lower mold, and a wedge block 2 is installed at one end of the sliding rod.

[0014] Through the above technical solution, the upper and lower ends of the side of wedge block 2 close to wedge block 1 are also inclined, and its inclination angle is the same as that of wedge block 1. When wedge block 1 contacts wedge block 2 during the up and down movement, the inclined surface of wedge block 1 will squeeze the inclined surface of wedge block 2, causing wedge block 2 to slide toward the lower mold, thereby driving the sliding rod to push into the lower mold.

[0015] The utility model is further configured as follows: a demoulding ring is fixed to the other end of the sliding rod, and a return spring is arranged on the outside of the sliding rod.

[0016] Through the above technical solution, the shape and size of the demolding ring match the annular groove. When wedge block 1 does not squeeze wedge block 2, the demolding ring is located inside the annular groove. When wedge block 1 squeezes wedge block 2, the sliding rod will push the demolding ring out of the annular groove, thereby demolding the formed pipe. When wedge block 1 is no longer in contact with wedge block 2, the reset spring can push wedge block 2, so that wedge block 1, the sliding rod and the demolding ring are reset.

[0017] The present invention is further configured as follows: the cooling mechanism includes a liquid cooling channel opened inside the upper mold, and one end of the liquid cooling channel is connected to a liquid inlet interface, and the other end of the liquid cooling channel is connected to a liquid outlet interface.

[0018] Through the above technical solution, the lower mold is provided with the same cooling mechanism as the upper mold. The liquid inlet interface can be connected to an external pressure cooling liquid source, and the liquid outlet interface can be connected to an external cooling liquid circulation mechanism. The liquid cooling channel is serpentine. When the coolant passes through the liquid cooling channel, it can effectively cool the material liquid in the upper mold and the lower mold, thereby speeding up the pipe forming speed and effectively improving the working efficiency of the device.

[0019] The utility model is further configured as follows: the base, the lower mold, the inner mold and the upper mold are all made of stainless steel.

[0020] Through the above technical solution, the base, lower mold, inner mold and upper mold made of stainless steel effectively improve the strength of the device and can also improve the heat dissipation and cooling efficiency of the device.

[0021] The beneficial effects of the utility model are as follows:

[0022] 1. The utility model realizes automatic demoulding of the pipe during mold opening by arranging a lifting mechanism, an arm pressing mechanism, and a demoulding mechanism, without requiring additional manual operation and reducing the use of telescopic cylinders, thereby improving the convenience of the device and reducing the production cost of the device.

[0023] 2. The utility model can cool the upper mold and the lower mold through the arrangement of the lower mold, the upper mold and the cooling mechanism, thereby increasing the speed of cooling and forming the pipeline, which is beneficial to improving the production efficiency of the device.

[0029] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.

[0030] See also Figures 1-4 , a mold for processing anti-corrosion and thermal insulation pipes, including a base 1 and a lower mold 2, the top of the base 1 is fixed with the lower mold 2, and the inner mold 3 is fixed on the inner side of the lower mold 2, an annular groove 4 is opened on the inner wall of one side of the lower mold 2, the rear end of the base 1 is provided with a lifting mechanism 5, and the inner side of the lifting mechanism 5 is provided with an upper mold 6, the lifting mechanism 5 includes a slide groove 501 fixed to the rear end of the base 1, and a top plate 502 is fixed on the top of the slide groove 501, and a telescopic rod 503 is installed on the top of the top plate 502, the rear end of the upper mold 6 is slidably connected with the slide groove 501, the upper mold 6 is fixedly installed on the telescopic end of the telescopic rod 503, the telescopic rod 503 can drive the upper mold 6 to move up and down, so that the upper mold 6 and the lower mold 2 produce relative movement, realizing mold closing and mold opening, and the slide groove 501 can limit the upper mold 6 to ensure the accuracy of mold closing.

[0031] like Figure 1 and Figure 3 As shown, a pressure arm mechanism 7 is fixed at one end of the upper mold 6, and the pressure arm mechanism 7 includes a fixed seat 701 installed at one end of the upper mold 6, and a connecting arm 702 is fixed on the fixed seat 701, and a wedge block 703 is installed at the bottom end of the connecting arm 702. The upper and lower ends of one side of the wedge block 703 are both inclined. The upper mold 6 can drive the fixed seat 701, the connecting arm 702 and the wedge block 703 to move up and down. When the wedge block 703 moves up and down, it can press the demoulding mechanism 8 to perform demoulding.

[0032] like Figure 1 and Figure 3As shown, a demoulding mechanism 8 is provided on the outer wall of the lower mold 2 near the annular groove 4. The demoulding mechanism 8 includes a sliding rod 801 slidably provided on one side of the inner wall of the lower mold 2, and a wedge block 2 802 is installed at one end of the sliding rod 801, and a demoulding ring 804 is fixed at the other end of the sliding rod 801.

The liquid cooling channel 1101 is serpentine. When the coolant passes through the liquid cooling channel 1101, it can effectively cool the material liquid in the upper mold 6 and the lower mold 2, thereby speeding up the pipe forming speed and effectively improving the working efficiency of the device.

[0034] like Figure 1 and Figure 2 As shown, the base 1, lower mold 2, inner mold 3 and upper mold 6 are all made of stainless steel. The base 1, lower mold 2, inner mold 3 and upper mold 6 made of stainless steel effectively improve the strength of the device and can also improve the heat dissipation and cooling efficiency of the device.

[0035] When the present invention is in use, the liquid injection interface 9 is first connected to the liquid pipeline, and then the cooling mechanism 11 is connected to the cooling liquid inlet pipe and the liquid outlet pipe. The telescopic rod 503 drives the upper mold 6 and the lower mold 2 to close the mold. At this time, a tubular cavity is formed between the upper mold 6, the lower mold 2 and the inner mold 3. The liquid is injected from the liquid injection interface 9, and the excess gas will be discharged from the exhaust port 10.
