[0002] The pressing equipment for producing metal-core rubber valve seats is a type of mechanical equipment specifically designed for manufacturing metal-core rubber valve seats. Metal-core rubber valve seats are commonly used in valve components in hydraulic and pneumatic systems, possessing wear resistance, sealing properties, and high-pressure resistance. The production process typically involves pressing technology to ensure a tight bond between the metal core and the rubber material, forming a high-strength and durable valve seat. The mold loaded with raw materials is fed into the pressing machine, where it is pressed under pressure. This process tightly bonds the rubber material to the metal core and shapes it.
[0003] After the metal core rubber valve seat is pressed, it needs to be removed from the mold by the workers and placed on the ground. This process is time-consuming and labor-intensive. Some pressing equipment is equipped with an inclined plate to unload the valve seat. The valve seat descends at a fast speed, so the impact force with the ground is greater, and the surface of the valve seat is easily damaged. Therefore, it is particularly important to design a pressing equipment for the production of metal core rubber valve seats. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. This utility model incorporates a feeding plate, an embedding rod, a bonding block, a buffer plate, a pressure-resistant plate, and a spring. After pressing, the valve seat is removed from the inside of the driven template and placed on the surface of the feeding plate. The valve seat can be fed by tilting the plate, saving workers time and effort in handling the valve seat.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figure 1-4 This utility model provides a technical solution for a pressing device for producing metal core rubber valve seats:
[0022] Example 1:
[0023] like Figure 1-3 As shown, a pressing device for producing metal-core rubber valve seats includes a pressing base 1, a pressing frame 2, a hydraulic system 3, a fixed template 4, and a movable template 5. The pressing frame 2 is located on top of the pressing base 1, and the hydraulic system 3 is located on top of the pressing frame 2. The top of the fixed template 4 is connected to the output shaft of the hydraulic system 3. The movable template 5 is located on top of the pressing base 1. A storage compartment 6 is movably installed on one side of the pressing base 1. Two arc-shaped blocks 7 are fixedly installed on one side of the pressing base 1. A limit shaft 8 is provided between the inner walls of the two arc-shaped blocks 7, and a feeding plate 10 is sleeved on one end of the limit shaft 8. Both sides of the feeding plate 10 are provided with arc-shaped grooves 11, and each of the two arc-shaped grooves 11 is provided with an embedded rod 12. The feeding plate 10 is provided with a buffer plate 14, and two anti-pressure plates 15 are provided on one side of the buffer plate 14. The valve seat can be fed according to the tilt angle, saving the time and effort of the workers to move the valve seat. After the valve seat applies pressure to the buffer plate 14, the fitting block 13 can move at one end of the embedded rod 12. The spring 16 can be compressed and deformed after being stressed, converting kinetic energy into elastic potential energy, reducing the impact force between the valve seat and the surface of the buffer plate 14.
[0024] Example 2:
[0025] Based on Example 1, such as Figure 1 and Figure 4As shown, two bonding blocks 13 are fixedly installed on both sides of the buffer plate 14. The two bonding blocks 13 are movably sleeved on one end of the two embedded rods 12 respectively. Springs 16 are wound around the outside of the two embedded rods 12. One end of the two springs 16 is fixedly connected to one side of the two bonding blocks 13 respectively. One side of the two pressure plates 15 is fixedly connected to one side of the buffer plate 14 respectively. The bottom surface of the two pressure plates 15 is in contact with the surface of the feeding plate 10. By setting the arc block 7, the limiting shaft 8, the limiting rod 9 and the arc groove 11, the feeding plate 10 is installed on one side of the pressing seat 1 through the two arc blocks 7. After the operator rotates the limiting rod 9, it can drive the limiting shaft 8 fixedly connected to it to rotate, which in turn drives the feeding plate 10 fixedly sleeved to it to rotate, thereby adjusting the tilt angle of the feeding plate 10.
[0026] Working Principle: The pressing equipment for producing metal-core rubber valve seats is a specialized machine for manufacturing these seats. Metal-core rubber valve seats are commonly used in valve components of hydraulic and pneumatic systems, possessing wear resistance, sealing properties, and high-pressure resistance. The production process typically involves pressing technology to ensure a tight bond between the metal core and rubber material, forming a high-strength, durable valve seat. A mold loaded with raw materials is fed into the pressing machine, where it is pressed under pressure. This process tightly bonds the rubber material to the metal core and shapes it. After pressing, the metal-core rubber valve seat needs to be removed from the mold and transported to the ground, a time-consuming and labor-intensive process. Some pressing equipment is equipped with inclined plates for unloading the valve seat, resulting in a rapid descent and significant impact force upon contact with the ground, potentially damaging the valve seat surface. Therefore, designing a pressing device specifically for producing metal-core rubber valve seats is crucial. After the valve seat is removed from the inside of the driven template 5, it is placed on the surface of the feeding plate 10. The valve seat can be fed according to the tilt angle, saving the time and effort of the workers to move the valve seat. After the valve seat applies pressure to the buffer plate 14, the fitting block 13 can move at one end of the embedded rod 12. The spring 16 can be compressed and deformed after being stressed, converting kinetic energy into elastic potential energy, reducing the impact force between the valve seat and the surface of the buffer plate 14. The feeding plate 10 is installed on one side of the pressing seat 1 by two arc blocks 7. After the worker rotates the limiting rod 9, it can drive the limiting shaft 8 fixedly connected to it to rotate, which will also drive the feeding plate 10 fixedly sleeved to it to rotate, thereby adjusting the tilt angle of the feeding plate 10. After the valve seat collides with the buffer plate 14, as the buffer plate 14 moves, the two anti-pressure plates 15 can move on the top of the feeding plate 10. The anti-pressure plates 15 mainly support one side of the buffer plate 14.
