Description

Technical Field

[0001] The utility model relates to the technical field of production of sealing diaphragms, in particular to a pressing die for production of sealing diaphragms. Background Art

[0002] As an important sealing component, diaphragms are widely used in valves, control valves, automatic mechanical followers, switches, and counters. Their excellent resistance to heat, media, pressure, and flexure makes them indispensable in industrial production. Diaphragm pressing dies are key equipment in their production, and their operating principle involves three processes: heating, pressing, and forming the material.

[0003] In the prior art, a pressing die for producing a sealing diaphragm sheet is proposed in publication number CN214687548U, which includes a basic component and a workpiece extraction component. The basic component includes a workbench, a support column, a frame, a hydraulic cylinder, a support plate, a first mold body, a second mold body and an injection tube. The support column is fixed to the lower surface of the workbench, the frame is fixed to the upper surface of the workbench, and the hydraulic cylinder is fixed to the upper surface of the frame. When in use, the adsorbed diaphragm sheet is placed on a conveyor under the joint action of the motor, the first cylinder, the second cylinder and the vacuum generator, so that the diaphragm sheet is conveyed out by the conveyor. The diaphragm sheet is continuously produced according to the above steps. The pressing die does not require manual removal of the diaphragm sheet from the second mold body, which saves manpower and improves the production efficiency of the diaphragm sheet.

[0004] When this application is in use, the adsorbed diaphragm is placed on a conveyor under the joint action of the motor, the first cylinder, the second cylinder and the vacuum generator, so that the diaphragm is conveyed out by the conveyor. However, when the diaphragm is taken out, the pressing mold for pressing and forming needs to be stopped, and it takes a certain amount of time to take out the diaphragm, thereby reducing the work efficiency of the diaphragm pressing. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a pressing die for producing a sealing diaphragm sheet, so as to solve the technical problems mentioned in the above background technology.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions:

[0007] A pressing mold for producing a sealing diaphragm comprises a bottom mold base, a guide column and a top mold base, wherein a molding groove is provided on the top side of the bottom mold base, a molding protrusion is fixedly connected to the bottom side of the top mold base, the guide column is fixedly installed on the top side of the bottom mold base, the top mold base and the guide column are slidably connected, a driving motor is fixedly connected to the middle part of the top side of the top mold base, the output shaft of the driving motor extends into the top mold base and is provided with a demolding part, and an auxiliary part is provided on the side of the bottom mold base.

[0008] In a preferred example, the present invention can be further configured as follows: the demoulding member includes a telescopic rod, the telescopic rod is fixedly mounted on the bottom end of the output shaft of the driving motor, and the bottom end of the telescopic rod is slidably connected to the top mold base.

[0009] In a preferred example, the present invention can be further configured as follows: the bottom end of the telescopic rod extends into the molded protrusion, the bottom end of the telescopic rod is fixedly connected to a threaded rod, the bottom end of the threaded rod extends below the molded protrusion, and the threaded rod is threadedly connected to the molded protrusion.

[0010] In a preferred example, the present invention can be further configured as follows: an empty groove is opened in the forming protrusion, a number of pore-forming columns are provided on the bottom side of the forming protrusion, the top end of the pore-forming column extends into the empty groove, and the pore-forming column is slidably connected to the forming protrusion.

[0011] In a preferred example, the present invention can be further configured as follows: a positioning sleeve is rotatably connected to the outer peripheral wall of the threaded rod, and a linkage rod is connected between the outer peripheral wall of the positioning sleeve and the outer peripheral wall of the hole-forming column.

[0012] In a preferred example, the present invention can be further configured as follows: the auxiliary component includes two columns, the two columns are fixedly mounted on the sides of the bottom mold base, and a guide tooth plate is slidably connected between the two columns.

[0013] In a preferred example, the present invention can be further configured as follows: a driving gear rod is rotatably connected between the two columns, the driving gear rod is engaged with the guide gear plate, a guide motor is fixedly installed on the side of one of the columns, and the output end of the guide motor is connected to the driving gear rod.

[0014] In summary, the present invention has at least one of the following beneficial technical effects:

[0015] 1. This pressing die for producing a sealing diaphragm can start a driving motor when the top die seat rises during use, so that the driving motor drives the threaded rod to rotate and move, allowing the diaphragm to separate from the threaded rod and the hole-forming column, thereby achieving a rapid demoulding effect. Subsequently, the diaphragm separated from the die is transported to the outside by an auxiliary component, achieving the effect of transporting the diaphragm out of the pressing die. As a result, the mold can directly inject softened raw materials when the diaphragm is demoulded and transported. After the raw materials are injected, the diaphragm is transported, so that the next pressing can be carried out quickly, thereby improving the production efficiency of the diaphragm.

[0016] 2. This is a pressing die for producing a sealing diaphragm. After the diaphragm is formed, the pore-forming column forms multiple holes on the side of the diaphragm. Since some diaphragms require holes on the side, the holes can be formed directly during the pressing process, saving the time of subsequent punching. At the same time, the rotation of the threaded rod is prevented from driving the rotation of the diaphragm, thereby preventing the demolding of the diaphragm.

[0017] 3. This kind of pressing mold for producing sealing diaphragm sheets, after the forming protrusion rises to a certain distance, the guide motor drives the driving gear rod to rotate, and then drives the guide tooth plate to move to the bottom of the forming protrusion, wherein the guide tooth plate is inclined. When the guide tooth plate moves to the bottom of the forming protrusion, the diaphragm sheet is just demolded and will fall to the top side of the guide tooth plate. Through the inclined guide tooth plate, the diaphragm sheet will detach from the pressing mold along the inclined direction of the guide plate, thereby achieving the effect of automatic conveying.

DETAILED DESCRIPTION

[0025] The present invention will be described in further detail below with reference to the accompanying drawings. Example

[0026] Reference Figure 1-Figure 5 The utility model discloses a pressing mold for producing a sealing diaphragm, comprising a bottom mold base 1, a guide column 2 and a top mold base 3. The top side of the bottom mold base 1 is provided with a molding groove 4, and the bottom side of the top mold base 3 is fixedly connected with a molding protrusion 5. The guide column 2 is fixedly installed on the top side of the bottom mold base 1, and the top mold base 3 and the guide column 2 are slidably connected. A driving motor 6 is fixedly connected to the middle part of the top side of the top mold base 3, and the output shaft of the driving motor 6 extends into the top mold base 3 and is provided with a demolding part 7. The side of the bottom mold base 1 is provided with an auxiliary part 8.

[0027] In this embodiment, the mixed and softened raw material is injected into the molding groove 4, and then the top mold base 3 can be driven by a hydraulic cylinder or a motor to move downward on the guide column 2, so that the molding protrusion 5 enters the molding groove 4, and the mixed and softened raw material is molded. The formed sealing diaphragm will rise through the demolding part 7 following the rise of the fixed mold, so that the sealing diaphragm moves upward with the demolding part 7, and then the auxiliary part 8 is started, and the demolding part 7 lowers the diaphragm to the auxiliary part 8 when demolding, and then the diaphragm is separated from the pressing mold. When the top mold base 3 rises, the raw material needed for the next time can be injected into the molding groove 4, and the diaphragm is demolded and sent away through the auxiliary part 8. Then, after the injection of the raw material is completed, the top mold base 3 can be directly driven to move downward in and out of the next pressing work, thereby saving the time for demolding the diaphragm and improving the efficiency of diaphragm production.

[0028] In a further preferred embodiment of the present invention, Figure 2-4As shown, the demolding member 7 includes a telescopic rod 9, which is fixedly mounted on the bottom end of the output shaft of the drive motor 6. The bottom end of the telescopic rod 9 is slidingly connected to the top mold base 3, and the bottom end of the telescopic rod 9 extends into the molding protrusion 5. The bottom end of the telescopic rod 9 is fixedly connected to a threaded rod 10, and the bottom end of the threaded rod 10 extends to the bottom of the molding protrusion 5. The threaded rod 10 is threadedly connected to the molding protrusion 5.

[0029] In this embodiment, when demoulding, the top mold base 3 is moved upward. When it moves to a certain distance, the auxiliary component 8 and the drive motor 6 are started. The drive motor 6 will drive the rotation of the telescopic rod 9, and at the same time drive the threaded rod 10 to rotate. When the threaded rod 10 rotates, it will move upward in the molding protrusion 5. When the threaded rod 10 moves upward, the diaphragm will gradually separate from the threaded rod 10. After the diaphragm is separated from the threaded rod 10, the demoulding effect will be achieved.

[0030] When the threaded rod 10 is in the pressing operation, the diaphragm is pressed by the forming groove 4 and the forming protrusion 5 so as to fit with the provided threaded rod 10. At the same time, the diaphragm wraps around the threaded rod 10 and is threadedly connected to the threaded rod 10, so that the diaphragm can be driven to rise when the top mold base 3 rises. The rotation of the threaded rod 10 will gradually separate the diaphragm, thereby achieving the demoulding effect, and then the diaphragm falls into the auxiliary component 8 for transportation;

[0031] In addition, the diameter of the threaded rod 10 is smaller than the diameter of the subsequent punching hole of the diaphragm, so as to avoid affecting the subsequent punching hole of the diaphragm.

[0032] In a further preferred embodiment of the present invention, Figure 2-4 As shown, a hollow groove 11 is provided in the forming protrusion 5, and a number of hole-forming columns 12 are provided on the bottom side of the forming protrusion 5. The top end of the hole-forming column 12 extends into the hollow groove 11, and the hole-forming column 12 is slidingly connected to the forming protrusion 5. The outer peripheral wall of the threaded rod 10 is rotatably connected to a positioning sleeve 13, and a linkage rod 14 is connected between the outer peripheral wall of the positioning sleeve 13 and the outer peripheral wall of the hole-forming column 12.

[0033] In this embodiment, when the threaded rod 10 rotates and rises, the positioning sleeve 13 provided therein is rotatably connected to the threaded rod 10, and the positioning sleeve 13 is connected to the pore-forming column 12 provided therein via a linkage rod 14. Therefore, when the threaded rod 10 rises, the positioning sleeve 13 will be driven to move upward, and at the same time, the pore-forming column 12 will be driven to move upward via the linkage rod 14, thereby separating the pore-forming column 12 from the diaphragm.

[0034] After the diaphragm is formed, a plurality of holes will be formed on the side of the diaphragm by the hole-forming column 12. Since some diaphragms need to have holes on the side, the holes can be formed directly during the pressing process, which saves the time for subsequent punching and avoids the rotation of the threaded rod 10 driving the rotation of the diaphragm, thereby affecting the demolding of the diaphragm.

[0035] In a further preferred embodiment of the present invention, Figure 5 As shown, the auxiliary part 8 includes two columns 15, and the two columns 15 are fixedly installed on the sides of the bottom mold base 1. A guide gear plate 16 is slidably connected between the two columns 15, and a driving gear rod 17 is rotatably connected between the two columns 15. The driving gear rod 17 is engaged with the guide gear plate 16. A guide motor 18 is fixedly installed on the side of one of the columns 15, and the output end of the guide motor 18 is connected to the driving gear rod 17.

[0036] In this embodiment, after the forming protrusion 5 rises to a certain distance, the guide motor 18 drives the driving gear rod 17 to rotate, and then drives the guide tooth plate 16 to move to the bottom of the forming protrusion 5, wherein the guide tooth plate 16 is inclined. When the guide tooth plate 16 moves to the bottom of the forming protrusion 5, the diaphragm is just demolded and falls to the top side of the guide tooth plate 16. Through the inclined guide tooth plate 16, the diaphragm will detach from the pressing mold along the inclined direction of the guide plate, thereby achieving the effect of automatic conveying.

[0037] The embodiments of this specific implementation method are all preferred embodiments of the present utility model, and are not intended to limit the scope of protection of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the scope of protection of the present utility model.
