Description

Technical Field

[0001] The utility model relates to the technical field of Y-shaped sealing ring demoulding, in particular to a highly efficient demoulding tooling for extremely small Y-shaped sealing ring products. Background Art

[0002] Y-shaped sealing ring products are widely used in the sealing of various automotive systems. They are Y-shaped in cross section and are a typical lip-shaped sealing ring. They are widely used in reciprocating dynamic sealing and axial static sealing. They are an important type of automotive sealing safety parts with good pressure resistance, wide applicable pressure range, reliable sealing performance, and easy installation. With the gradual rise of hydrogen energy vehicles in recent years, the Y-shaped sealing ring products in the hydrogen storage tank system have gradually become smaller due to the requirements of hydrogen flow control, and the demand is high. There is still a blank in China, which poses new challenges to the production and demolding requirements and efficiency of Y-shaped sealing ring products. The existing demolding equipment has the following problems:

[0003] 1: The product is extremely small, and the sealing surface of the product does not allow for demolding. The only way to demold is to turn the product upside down in the mold and cannot be demolded.

[0004] 2: The products are severely deformed when demolding is done by force, the efficiency is extremely low, there is no production efficiency, and it has no commercial value. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides an efficient demoulding tooling for an extremely small Y-shaped sealing ring product, which solves the above-mentioned problems.

[0006] To achieve the above purpose, the utility model is implemented through the following technical solutions: an efficient demoulding tooling for a very small Y-shaped sealing ring product, comprising a blowing tooling arranged above the mold and a positioning component for positioning the blowing tooling, the inner cavity of the mold is provided with a workpiece forming groove for forming the Y-shaped sealing ring, the blowing tooling comprises a blowing rod threadedly connected to an external air source pipeline through an upper threaded section and a pressure regulating cover slidably connected to the surface of the blowing rod, and the centers of the blowing rod and the threaded section are both provided with an air inlet channel;

[0007] The bottoms of the blowing rod and the pressure regulating cover are in contact with the surface of the molded part, and a pressure relief hole is provided on the surface of the pressure regulating cover;

[0008] The bottom end of the blowing rod is provided with a retention ring which protrudes outward in an annular shape and is used to limit the sealing ring;

[0009] The following steps are included when using

[0010] 1. Positioning: Assemble the positioning assembly, connect the connecting frame to the top of the threaded section, and then connect the blowing rod to the external air pipe through the threaded section. The operator holds the air pipe with a switch to operate, position the blowing tooling and the mold, take out the molded lower mold, and then insert the blowing rod into the workpiece molding groove. At this time, the retention ring is located above the Y-shaped sealing ring, and the pressure regulating cover is located below the pressing plate. When pressing down, the lifting rod abuts against the surface of the mold and then rises upward in the sleeve, pushing the transmission frame to rotate along the rotating rod, and then the pressing plate moves downward to squeeze the pressure regulating cover, so that the pressure regulating cover can be tightly attached to the top of the workpiece molding groove. Through the structural design of the positioning assembly, while not interfering with normal processing, when the blowing rod is squeezed on the surface of the mold, the pressure regulating cover is automatically pressed by the lever principle, so that it is squeezed on the top of the mold to form a relatively sealed cavity;

[0011] 2. The operator turns on the air pipe switch and then turns it off after one second. When it is turned on again, the air flow is instantly blown out along the air inlet channel of the blowing rod to form a severe air pressure in the workpiece forming groove, blowing the Y-shaped sealing ring upward and moving upward along the blowing rod. When passing through the retention ring, it is deformed under the air pressure, and then the air pressure is discharged along the pressure relief hole on the surface of the pressure regulating cover. At this time, the air pressure returns to normal, and then the Y-shaped sealing ring falls along the blowing rod and is blocked by the retention ring, completing the demoulding and discharging. The air pressure in the pressure regulating cover is rapidly increased by blowing, causing the Y-shaped sealing ring to detach from the mold. During the detachment and rising process of the Y-shaped sealing ring, the Y-shaped sealing ring is locked by the retention ring designed at the tail of the blowing rod.

[0012] 3. Then continue to demould the next mold and put a large number of Y-shaped sealing rings on the blowing rod.

[0013] 4. Take out the product: gently push the pressure regulating cover up and down, squeeze the Y-shaped sealing ring to make it deform and fall off the retention ring, and fall from the blowing rod, so as to eject multiple products. An innovative structure of efficient demolding tooling for extremely small Y-shaped sealing ring products is created to achieve rapid demolding of multiple products with extremely high demolding efficiency: product demolding is achieved through instantaneous pressurization and pressure relief, which has a certain efficiency. At the same time, the blowing tooling can hold multiple products, and there is no need to remove the Y-shaped sealing ring every time the mold is ejected, which further improves the efficiency.

[0014] As a further solution of the utility model: the threaded section is connected to an external gas source pipeline for instantaneous pressure increase and pressure relief.

[0015] As a further solution of the utility model: the retention ring is arranged in the middle of the mold forming sealing gasket, and the end thereof extends into the inner cavity of the workpiece forming groove, and the pressure regulating cover is arranged on the outer side of the Y-shaped sealing ring.

[0016] As a further solution of the utility model: the outer diameter of the retention ring is smaller than the inner diameter of the Y-shaped sealing ring.

[0017] As a further solution of the utility model: the blowing rod is a hollow cylindrical shape, and the outer surface is slidably sealed with the inner cavity of the pressure regulating cover.

[0018] As a further solution of the utility model: the positioning assembly includes a connecting frame threadedly connected above the threaded section, both sides of the bottom of the connecting frame are fixedly connected with sleeves, the inner cavities of the two sleeves are slidably connected with lifting rods, one side of the sleeve is fixedly connected with a fixing plate, the surface of the fixing plate is rotatably connected to the transmission frame through a rotating rod, the end of the transmission frame passes through and extends to the inner cavity of the sleeve, the end of the transmission frame is movably connected to the inner cavity of the sleeve, the top of the lifting rod abuts against the bottom of the transmission frame, one end of the transmission frame is fixedly connected with a pressure plate abutting against the surface of the pressure regulating cover, the surface of the lifting rod is sleeved with a torsion spring abutting against the inner cavity of the transmission frame, the transmission frame is limited by the setting of the torsion spring, and the torsion spring is compressed when the transmission frame rotates downward close to one end of the pressure regulating cover.

[0019] Compared with the prior art, the utility model has the following beneficial effects:

[0020] 1. The utility model can realize rapid demolding of multiple products and has extremely high demolding efficiency: product demolding is realized by instantaneous pressurization and pressure relief, which has a certain efficiency. At the same time, the blowing tooling can hold multiple products, and there is no need to remove the Y-shaped sealing ring every time the mold is ejected, so the efficiency is further improved.

[0021] 2. In the utility model, when pressing down, the lifting rod abuts against the surface of the mold and then rises upward in the sleeve, pushing the transmission frame to rotate along the rotating rod, and then the pressure plate moves downward to squeeze the pressure regulating cover, so that the pressure regulating cover can be tightly attached to the top of the workpiece forming groove through the structural design of the positioning component. While not interfering with normal processing, when the blowing rod is pressed on the surface of the mold, the pressure regulating cover is automatically pressed through the lever principle, so that it is squeezed above the mold to form a relatively sealed cavity.
