A mold with replaceable upper and lower mold bodies

Abstract

This utility model discloses a mold with interchangeable upper and lower mold bodies, including an upper module, a fixing block, a lower module, and a fixing rod. By using the upper module, fixing block, lower module, fixing rod, adjustment mechanism, and positioning mechanism in conjunction, this utility model addresses the challenge of changing mold bodies when manufacturing valves. Previously, changing mold bodies required separating the upper and lower mold bodies, which was laborious and slow, reducing efficiency. This utility model provides a mold with interchangeable upper and lower mold bodies, allowing for targeted mold body changes based on production needs, reducing production costs while increasing efficiency and speed.

Description

Technical Field

[0001] The utility model belongs to the technical field of valve casting, and particularly relates to a mold with replaceable upper and lower mold bodies. Background Art

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and adjust and control the parameters (temperature, pressure, and flow) of the conveying medium. Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal, and radioactive media. According to their functions, they can be divided into shut-off valves, check valves, and regulating valves. Valves are now widely used, and valves are usually manufactured using corresponding types of molds during production.

[0003] The problem with the prior art is that when manufacturing valves, due to the different sizes of valves to be processed, valves of different specifications need to be replaced for production. However, when replacing molds of different specifications, the upper and lower molds need to be disassembled separately, which is laborious to replace, and cannot be adjusted quickly, thereby reducing work efficiency. In order to facilitate the replacement of the upper and lower molds, a mold in which both the upper and lower molds are replaceable is proposed. The molds can be replaced in a targeted manner according to production needs, thereby reducing production costs while speeding up work efficiency and providing replacement speed. Utility Model Content

However, when replacing mold bodies of different specifications, the upper and lower mold bodies need to be disassembled separately, which is laborious to replace, and they cannot be adjusted quickly, thereby reducing work efficiency. In order to facilitate the replacement of the upper and lower mold bodies, a mold with replaceable upper and lower mold bodies is proposed, which can replace the mold bodies in a targeted manner according to production needs, thereby reducing production costs while speeding up work efficiency and providing replacement speed.

The two bent rods 704 are movably connected to the inside of the positioning cavity 6 through a rotating shaft, and the bent rod 704 is used in conjunction with the positioning mechanism 8.

[0024] The above solution is adopted: by providing the adjustment mechanism 7, it is convenient for the staff to operate when replacing and adjusting the upper module 1 or the lower module 3, thereby simplifying the replacement process and improving work efficiency.

[0025] refer to Figure 3The positioning mechanism 8 includes a moving column 801, a positioning rod 802 and a tension spring 803. The right side of the moving column 801 passes through the right side of the bending rod 704. The left side of the moving column 801 is fixedly connected to the right side of the positioning rod 802. The opposite sides of the two positioning rods 802 are fixedly connected to the opposite sides of the two tension springs 803. The opposite sides of the two tension springs 803 are fixedly connected to the inner wall of the positioning cavity 6. The opposite sides of the two positioning rods 802 pass through the interior of the upper module 1 and the lower module 3.

[0026] By adopting the above solution, by providing the positioning mechanism 8, the upper module 1 and the lower module 3 can be stably fixed on the surface of the fixing block 2, so as to prevent the mold from loosening when in use, thereby preventing damage to the product.

[0027] refer to Figure 3 and Figure 4 The surfaces of the upper module 1 and the lower module 3 are both provided with fixing grooves 9, and the positioning rods 802 fit tightly during insertion.

[0028] By adopting the above solution, by providing the fixing groove 9, the positioning rod 802 can be accurately inserted into the fixing groove 9 when being plugged and fixed, thereby preventing it from being loosened during use.

[0029] refer to Figure 3 The front and rear sides of the positioning rod 802 are fixedly connected with limiting rods 10, and the interior of the positioning cavity 6 is provided with limiting grooves 11 used in conjunction with the limiting rods 10.

[0035] The working principle of this utility model:

[0036] When in use, the moving rod 701 is pulled backward, and the moving rod 701 drives the vertical rod 702 to move backward. The vertical rod 702 drives the fixed column 703 to move backward according to the moving trajectory provided by the limit groove 13, and the surface of the fixed column 703 squeezes the inner wall of the travel groove 12 to make the two bent rods 704 rotate to the opposite side. During rotation, the inner wall of the travel groove 12 squeezes the surface of the moving column 801 to make the two moving columns 801 move to the opposite side, and the moving column 801 drives the positioning rod 802 to move to the opposite side according to the moving trajectory provided by the limiting groove 11. The positioning rod 802 stretches the tension spring 803 while moving, so that the positioning rod 802 moves to the inside of the positioning cavity 6. At this time, the fixing rod 4 is pulled out, and the upper module 1 or the lower module 3 can be disassembled and replaced, and it is pulled out through the sliding groove 5. After completion, the fixing rod 4 is reinserted, and the moving rod 701 is released. The positioning rod 802 is reinserted into the inside of the fixing groove 9 by the return force of the tension spring 803.

[0037] To sum up: the mold with replaceable upper and lower mold bodies, by setting the upper module 1, the fixed block 2, the lower module 3, the fixed rod 4, the sliding groove 5, the positioning cavity 6, the adjusting mechanism 7, the moving rod 701, the vertical rod 702, the fixed column 703, the bending rod 704, the positioning mechanism 8, the moving column 801, the positioning rod 802, the tension spring 803, the fixed groove 9, the limiting rod 10, the limiting groove 11, the travel groove 12 and the limit groove 13, solves the problem that when the valve is produced and manufactured, due to the different sizes of valves to be processed, it is necessary to replace valves of different specifications for production. However, when replacing mold bodies of different specifications, the upper and lower mold bodies need to be disassembled separately, which is more laborious when replacing them, and they cannot be adjusted quickly, which reduces the work efficiency. In order to facilitate the replacement of the upper and lower mold bodies, a mold with replaceable upper and lower mold bodies is proposed. The mold body can be replaced in a targeted manner according to production needs, thereby reducing production costs while speeding up work efficiency and providing replacement speed.
