Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically to a molding mold for an electromagnetic valve housing. Background Technology

[0002] Solenoid valves are electromagnetically controlled industrial devices, fundamental components of automation systems used to control fluids. They are used in industrial control systems to adjust the direction, flow rate, speed, and other parameters of the medium. Solenoid valves can be used with different circuits to achieve the desired control, ensuring both precision and flexibility. Based on functional differences, solenoid valves can be classified into check valves, safety valves, directional control valves, speed regulating valves, etc.

[0003] In real life, the production of solenoid valve housings requires the use of molding dies. To facilitate the unloading of the molded workpiece, an ejector mechanism is usually set up to push the workpiece upward out of the mold cavity, separating it from the mold. However, this method still requires manual intervention to remove the workpiece after it is ejected from the mold, making it impossible to unload the molded workpiece at once, thus reducing the production efficiency of the workpiece. Therefore, a molding die for solenoid valve housings is needed. Utility Model Content

[0029] The unloading component includes two electric push rods 21. The telescopic ends of the two electric push rods 21 are fixedly provided with connecting seats 22. One end of the two connecting seats 22 on opposite sides is rotatably provided with a support rod 23. The opposite sides of the two support rods 23 are rotatably connected to the two sides of the unloading seat 15. The other end of the two connecting seats 22 on opposite sides is fixedly provided with a fixing frame 24. The inner walls of the two fixing frames 24 are slidably provided with connecting shafts 25. One end of the two connecting shafts 25 is provided with a connecting plate 26. The two sides of the connecting plate 26 are rotatably provided with connecting rods 27. The opposite sides of the two connecting rods 27 are provided with a top rod 28.

[0030] The electric push rod 21 is used to provide the driving force required for the unloading seat 15 to rotate and the ejector rod 28 to move upward to eject the material. The electric push rod 21 adopts the LAP35-V2 model. The outer wall of the electric push rod 21 is embedded in one side of the base 14. The inner wall width of the fixed frame 24 is adapted to the outer diameter of the connecting shaft 25. The top end of the ejector rod 28 passes through the top end of the unloading seat 15 and the inner bottom end of the stamping die 16, and slides with the unloading seat 15 and the stamping die 16. At the same time, the top end of the ejector rod 28 and the inner bottom end of the stamping die 16 are located on the same horizontal plane.

[0031] A stamping cylinder 17 is fixedly installed at the top of the forming frame 11, and a movable seat 12 is fixedly installed at the telescopic end of the stamping cylinder 17. A stamping upper die 13 is installed at the bottom of the movable seat 12.

[0032] The stamping cylinder 17 is used to provide the driving force required for the stamping upper die 13 to move down for stamping. A control panel is installed on one side of the forming frame 11. The stamping cylinder 17 and the electric push rod 21 are electrically connected to an external power source through the control panel. The moving seat 12 is slidably connected to the forming frame 11.

[0033] The bottom of each connecting seat 22 is fixedly provided with a first slider 29, and the outer walls of the two first sliders 29 are slidably connected to the top of the base 14 respectively.

[0034] The first slider 29 is T-shaped and is used to limit the movement of the connecting seat 22. The top of the base 14 has first grooves on both sides that are adapted to the first slider 29.

[0035] Both sides of the feeding seat 15 are provided with through grooves 151, and the inner side of the through grooves 151 is slidably connected to the outer wall of the connecting shaft 25.

[0036] The through groove 151 is used to allow the connecting shaft 25 to move and move, and the height of the through groove 151 is adapted to the outer diameter of the connecting shaft 25.

[0037] Two return springs 210 are fixedly provided on one side of the connecting plate 26, and one end of the two return springs 210 is fixedly connected to the inner side wall of the feeding seat 15.

[0038] Working principle: After the solenoid valve housing is formed by the upper stamping die 13 and the lower stamping die 16, when the workpiece needs to be unloaded, the electric push rod 21 is opened. The electric push rod 21 retracts and resets, causing the connecting seat 22 to move to the right. The rightward movement of the connecting seat 22 causes one end of the unloading seat 15 to rotate upward through the support rod 23. At the same time, the rightward movement of the connecting seat 22 causes the connecting shaft 25 to move through the fixed frame 24. The movement of the connecting shaft 25 causes the connecting plate 26 to move to the right. The rightward movement of the connecting plate 26 causes the ejector rod 28 to move upward through the connecting rod 27. The ejector rod 28 pushes the workpiece out of the lower stamping die 16 and makes it slide downward along the lower stamping die 16 for unloading. In this way, the formed workpiece can be unloaded in one go. The whole process does not require manual intervention for unloading, thereby improving the workpiece production efficiency.

[0039] Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, further includes:

[0040] The fixing component includes two movable blocks 31. Each of the two movable blocks 31 has a fixed insert rod 32 on its opposite side. Each of the two insert rods 32 has an elastic block 33 fixed on its outer wall. The two elastic blocks 33 are jointly provided with a fixing plate 34. One side of the fixing plate 34 is fixedly disposed on one side of the stamping die 16.

[0041] Two fixed components are provided, located on the left and right sides of the blanking seat 15 respectively. The connection method between the blanking seat 15 and the lower stamping die 16 is the same as the connection method between the movable seat 12 and the upper stamping die 13.

[0042] Each side of the movable block 31 is fixedly provided with a second slider 35, and the outer walls of the two second sliders 35 are slidably connected to one side of the unloading seat 15 respectively.

[0043] The second slider 35 is also T-shaped and is used to limit the movement of the moving block 31. Two second grooves that are adapted to the second slider 35 are symmetrically opened on both sides of the feeding seat 15.

[0044] Positioning rods 152 are fixedly provided on both sides of the top of the blanking seat 15, and the outer walls of the two positioning rods 152 respectively penetrate the top of the stamping die 16;

[0045] Two positioning rods 152 are arranged diagonally, and two positioning holes that are adapted to the positioning rods 152 are opened at the top of the stamping die 16.

[0046] Working principle: When molding the housing of different models of solenoid valves, press the elastic block 33 inward and move the two moving blocks 31 outward respectively. The movement of the moving blocks 31 drives the insert rod 32 to move outward until the insert rod 32 separates from the fixed plate 34. Then, remove the stamping lower die 16 upward, align the new stamping lower die 16 and engage it with the positioning rod 152. Then, move the two moving blocks 31 in opposite directions until the elastic block 33 engages with the fixed plate 34 on the new die. Similarly, replace the stamping upper die 13. This method facilitates the replacement of molding dies to meet the stamping requirements of different models of workpieces and improves the practicality of molding dies.
