Description

Technical Field

[0001] The utility model relates to the technical field of molds, and in particular to a flange pipe processing mold. Background Art

[0002] Flange pipes primarily consist of two parts: the pipe and the flange. The flange is the key component that connects the pipe to other equipment or pipelines. Flange pipes, through flange connections, make installation and removal of piping systems more convenient and quick, and are widely used in piping systems in industries such as petroleum, chemical, electric power, metallurgy, shipbuilding, and construction. The flange pipe manufacturing process requires the use of a mold. Molten metal is poured into the mold. After the metal cools and solidifies, the formed flange pipe blank is removed and subsequently cleaned, polished, and machined.

[0003] The mold consists of an upper mold, a lower mold, and a mold core. The mold core is located between the upper and lower molds during the processing, supporting and shaping the interior of the flange pipe. After forming, the upper and lower molds need to be disassembled to remove the flange pipe blank and the mold core. The flange pipe blank and the mold core are then separated, moved to a designated location, and the mold core is returned between the upper and lower molds. Currently, the upper mold is generally disassembled and moved to another location manually, the flange pipe blank and the mold core are removed, and the mold core is returned to the upper and lower molds. The upper mold is then manually moved back and locked with the upper and lower molds. This is time-consuming and labor-intensive, with low work efficiency. Utility Model Content

After the lifting mechanism is contracted, the upper mold is used to buckle with the lower mold.

[0010] Also includes,

[0011] A base, the base being located below the lower mold;

[0012] The support seat is horizontally slidably arranged on the base. After the support seat slides, it contacts or separates from the lower mold. The sliding direction of the support seat is perpendicular to the axial direction of the lower mold.

[0020] Also includes,

[0021] Lower connecting plates are provided at both ends of the lower mold;

[0022] An upper connecting plate is provided at both ends of the upper mold. After the upper mold is buckled with the lower mold, the upper connecting plate and the lower connecting plate are overlapped. The upper connecting plate and the lower connecting plate are detachably connected, and the upper end of the jacking mechanism is connected to the upper connecting plate.

[0023] The working principle and beneficial effects of the utility model are as follows: the lower mold is rotatably arranged on a support frame.

The lifting mechanism is then retracted to its initial position, and the upper mold is lowered to reengage with the lower mold. The mold core is again clamped between the upper and lower molds, and the next casting can be performed through the pouring gate. This eliminates the need for manual handling of the upper mold, saving time and effort, reducing labor intensity, improving work efficiency, and avoiding the safety risks associated with direct manual operation of the upper mold. With the lower mold opening facing downward after rotation, the weight of the flange pipe blank and mold core facilitates separation from the lower mold, reducing demolding difficulty.

For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0033] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0034] Example, see Figure 1~Figure 2 , which is an embodiment of the utility model, proposes a flange pipe processing mold, including a support frame 1, a lower mold 2, an upper mold 3, and a lifting mechanism 4. The lower mold 2 is rotatably set on the support frame 1. After the lower mold 2 rotates, the opening of the lower mold 2 is used to face downward; the upper mold 3 is used to be set above the lower mold 2; the lower end of the lifting mechanism 4 is connected to the support frame 1, and the upper end of the lifting mechanism 4 is used to be connected to the upper mold 3. After the lifting mechanism 4 is extended, the upper mold 3 is used to separate from the flange pipe blank 16. After the lifting mechanism 4 contracts, the upper mold 3 is used to buckle with the lower mold 2.

[0035] In this embodiment, both the lower mold 2 and the upper mold 3 have rectangular shapes. The left and right ends of the lower mold 2 are rotatably connected to the support frames 1 at the corresponding ends. A lifting mechanism 4 is provided on each of the left and right support frames 1. The upper ends of the left and right lifting mechanisms 4 are connected to the left and right ends of the upper mold 3, respectively. Initially, the lifting mechanism 4 is in a retracted state, the upper mold 3 and the lower mold 2 are fastened together, and the mold core 17 is clamped between the upper mold 3 and the lower mold 2. Casting is then performed through the casting port into the interiors of the upper mold 3 and the lower mold 2. After the flange tube blank 16 is formed, the lifting mechanism 4 is extended to separate the upper mold 3 from the flange tube blank 16. The lower mold 2 is then rotated so that the opening of the lower mold 2 faces downward, and the flange tube blank 16 is then separated from the lower mold 2. Then, the lower mold 2 is rotated again so that the opening of the lower mold 2 faces upward. After separating the core 17 from the flange tube blank 16, the core 17 is placed on the lower mold 2. Then, the lifting mechanism 4 is retracted to return to its initial state. The upper mold 3 descends and snaps together with the lower mold 2 again. The core 17 is clamped between the upper mold 3 and the lower mold 2 again, and the next casting is carried out through the casting port. This eliminates the need for manual handling of the upper mold 3, saves time and effort, reduces labor intensity, improves work efficiency, and avoids the safety risks that may be caused by manual direct operation of the upper mold 3. After the lower mold 2 is rotated, the opening faces downward. Under the action of the gravity of the flange tube blank 16 and the core 17, it is more conducive to separating the flange tube blank 16 from the lower mold 2, which can reduce the difficulty of demoulding. Through the expansion and contraction of the lifting mechanism 4 and the rotation of the lower mold 2, the demoulding of the flange tube blank 16 and the reset of the mold can be quickly achieved, ready for the next casting, which can greatly shorten the production cycle.

[0036] Furthermore, if Figure 1 and Figure 2 As shown, it also includes a base 5 and a support seat 6. The base 5 is located below the lower mold 2; the support seat 6 is horizontally slidably set on the base 5. After the support seat 6 slides, it contacts or separates from the lower mold 2. The sliding direction of the support seat 6 is set perpendicular to the axial direction of the lower mold 2. Initially, the lower end face of the lower mold 2 contacts the upper end face of the support seat 6. The support seat 6 plays a supporting and limiting role on the lower mold 2, and the lower mold 2 does not rotate. After the flange tube blank 16 is formed, the lifting mechanism 4 is extended to separate the upper mold 3 from the flange tube blank 16, and at the same time, the support seat 6 is moved to separate the support seat 6 from the lower mold 2. Then the lower mold 2 is rotated, which can reduce the influence of factors such as mold shaking on the processing accuracy. The sliding design of the support seat 6 allows the position to be quickly adjusted to contact the lower mold 2 when needed, providing support for subsequent operations and increasing the flexibility of operation.

[0037] Furthermore, if Figure 3 and Figure 4As shown, it also includes a material receiving baffle 7, which is arranged on one side of the support seat 6. The bottom surface of the material receiving baffle 7 contacts the upper end surface of the base 5. One end of the material receiving baffle 7 is connected to the support seat 6, and the upper end surface of the other end of the material receiving baffle 7 is bent and extended upward. After the support seat 6 slides, the material receiving baffle 7 is used to approach or move away from the lower mold 2. Taking the material receiving baffle 7 located on the rear side of the support seat 6 as an example, initially, the lower end face of the lower mold 2 contacts the upper end face of the support seat 6, and the material receiving baffle 7 is located behind the lower mold 2. After the flange tube blank 16 is formed, the support seat 6 is moved forward, and the support seat 6 drives the material receiving baffle 7 to move forward synchronously. After the support seat 6 is separated from the lower mold 2, the support seat 6 stops moving. At this time, the rear end of the material receiving baffle 7 is located behind the lower mold 2. When the lower mold 2 is rotated for demoulding, the material receiving baffle 7 can play a guiding and limiting role, so that the flange tube blank 16 falls between the material receiving baffle 7 and the support seat 6, preventing the flange tube blank 16 from sliding backward, which is convenient for subsequent collection and processing.

[0038] Furthermore, if Figure 1 、 Figure 2 and Figure 3 As shown, a dovetail groove 8 is provided on the upper end surface of the base 5, and a dovetail bar 9 is provided on the bottom of the support base 6 and the bottom of the material receiving baffle 7. The dovetail bar 9 is plugged into the dovetail groove 8 to form a sliding fit. Two left and right dovetail grooves 8 are provided on the base 5, and the length direction of the dovetail groove 8 is arranged along the front-to-back direction. Two left and right dovetail bars 9 are provided on the support base 6. The dovetail bars 9 cooperate with the dovetail groove 8 to provide good guidance and stability, ensuring that the support base 6 and the material receiving baffle 7 maintain linear motion during the sliding process without offset or shaking, which can improve the operating accuracy. At the same time, it can effectively prevent the support base 6 and the material receiving baffle 7 from accidentally falling off during operation, thereby ensuring the safety and reliability of the equipment.

[0039] Furthermore, if Figure 3 and Figure 4 As shown, the mold core baffle 10 is also included, and a mold core baffle 10 is provided at both ends of the material receiving baffle 7. The left and right ends of the mold core 17 are exposed outside the flange pipe blank 16. During operation, the mold core baffles 10 at the left and right ends can limit and protect the mold core 17, preventing the mold core 17 and the flange pipe blank 16 from deviating to the left and right directions, and at the same time protecting the mold core 17 and the flange pipe blank 16 from collision or damage.

[0040] Furthermore, if Figure 3 and Figure 4As shown, the core baffle 10 has a core removal hole 11, which is located at one end of the core baffle 10 near the support seat 6. The diameter of the core removal hole 11 is greater than or equal to the diameter of the core 17. The left and right core baffles 10 can limit the flange pipe blank 16. When the core 17 needs to be removed, it can be pushed out through the core removal hole 11, which is more convenient and can further improve work efficiency. The operation process is safe and reliable.

[0041] Furthermore, if Figure 3 and Figure 4 As shown, the diameter of the mold core removal hole 11 is larger than the diameter of the mold core 17 and smaller than the flange outer diameter of the flange pipe blank 16. The larger diameter of the mold core removal hole 11 facilitates the removal of the mold core 17, while the smaller diameter of the mold core removal hole 11 prevents the flange pipe blank 16 from accidentally falling, ensuring safe operation.

[0042] Furthermore, if Figure 3 and Figure 4 As shown, the mold core baffle 10 further includes a buffer layer 12, which is disposed on the material receiving baffle 7. When the flange pipe blank 16 falls onto the material receiving baffle 7, the buffer layer 12 acts as a buffer, reducing the impact of the flange pipe blank 16 on the material receiving baffle 7, thereby extending the service life of the material receiving baffle 7. It can also reduce the noise generated when the flange pipe blank 16 contacts the material receiving baffle 7, thereby improving the working environment. Similarly, when the material receiving baffle 7 is disposed at both ends of the core baffle 10, the buffer layer 12 is also disposed on the inner wall of the material receiving baffle 7.

[0043] Furthermore, if Figure 3 As shown, a limit baffle 13 is also included, which is provided on the base 5 and is located at one end of the base 5 away from the material receiving baffle 7. The limit baffle 13 can limit the sliding range of the support base 6, prevent the support base 6 from sliding excessively and separating from the base 5, and ensure the normal operation of the equipment.

[0044] Furthermore, if Figure 1 、 Figure 2 and Figure 3As shown, it also includes a lower connecting plate 14 and an upper connecting plate 15. The lower connecting plates 14 are provided at both ends of the lower mold 2; the upper connecting plates 15 are provided at both ends of the upper mold 3. After the upper mold 3 and the lower mold 2 are buckled together, the upper connecting plates 15 overlap the lower connecting plates 14. The upper connecting plates 15 and the lower connecting plates 14 are detachably connected, and the upper end of the lifting mechanism 4 is connected to the upper connecting plates 15. Two left and right lower connecting plates 14 are provided on the lower mold 2, and two left and right upper connecting plates 15 are provided on the upper mold 3. The ends of the upper connecting plates 15 away from the upper mold 3 protrude from the outside of the lower connecting plates 14, and the lifting mechanism 4 is located on the outside of the lower connecting plates 14. The overlapping and detachable connection of the lower connecting plates 14 and the upper connecting plates 15 makes the connection between the upper mold 3 and the lower mold 2 more compact and stable when buckled together, ensuring that the molds will not accidentally separate during the casting process and convenient disassembly.

[0045] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
