Description

Technical Field

[0001] This utility model belongs to the field of cutting mold technology, specifically relating to an O-ring rubber sealing cutting mold. Background Technology

[0002] Currently, rubber O-rings used often require secondary processing to meet specifications because the spare parts do not match the actual dimensions. This is typically done by grinding directly on a grinding wheel. However, this method involves checking dimensions while grinding, resulting in inaccurate angles, rough flatness, poor bonding quality, low efficiency, and significant safety hazards.

[0003] Patent application number 202120417020.4 discloses a rubber O-ring cutting device, relating to the field of rubber O-ring cutting devices. The rubber O-ring cutting device includes an L-shaped template, a blade, and a connecting frame. The L-shaped template consists of a vertical plate and a horizontal plate. The outer wall of the vertical plate has a semi-circular groove, and the upper surface of the vertical plate has an inclined blade cutting groove. Two L-shaped templates are hinged to form an inverted T-shaped mold, and the two semi-circular grooves are joined to form a cylindrical through hole. The connecting frame includes a lead screw and a connecting rod. The lower end of the lead screw is hinged to the horizontal plate, and the upper end of the lead screw is connected to the connecting rod. A cylinder is fixed on the connecting rod, and the piston rod end of the cylinder is connected to the blade. The blade and the blade cutting groove are located in the same plane.

[0004] The above technical solution uses a blade holder to position the blade before cutting the O-ring. Since the inner and outer rings of the O-ring need to be cut separately during production, it is impossible to keep the rubber material fixed during the cutting process. As a result, the O-ring is prone to misalignment when cutting the outer and inner rings, which can lead to the O-ring breaking. Utility Model Content

[0005] (1) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, the purpose of this utility model is to provide an O-ring rubber seal cutting mold. This O-ring rubber seal cutting mold aims to solve the technical problem in existing technologies where the rubber material cannot be kept fixed during the cutting process, leading to misalignment of the O-ring rubber seal when cutting the outer and inner rings, resulting in the O-ring rubber seal breaking.

[0007] (2) Technical solution

[0008] To solve the above-mentioned technical problems, this utility model provides an O-ring rubber sealing cut mold, which includes a lower mold and an upper mold disposed above the lower mold. The top of the lower mold has multiple screw holes, and a positioning rod inserted into the upper mold is fixed at the top of the lower mold. A spring that abuts against the upper mold is sleeved on the top of the positioning rod. A base is threaded into the screw holes, and a sealing ring receiving groove is formed at the top of the base. A cut seat is fixed at the bottom of the lower mold, and a connecting seat is fixed on the cut seat. An inner ring cutting blade and an outer ring cutting blade are respectively fixed at the bottom of the connecting seat.

[0009] When using this technical solution, a base is threaded into a screw hole at the top of the upper mold, and a sealing ring receiving groove is provided on the base. Multiple cutting seats are fixed to the bottom of the upper mold. As the lower mold moves downward via the positioning rod, the outer and inner ring cutting blades on the connecting seat cut the rubber plate placed at the top of the upper mold. During the cutting process, the rubber ring is squeezed into the sealing ring receiving groove, facilitating simultaneous cutting of the outer and inner rings of the rubber ring. This avoids errors and rubber ring breakage caused by cutting the inner and outer rings separately, thus improving the cutting efficiency of O-ring rubber seals. Effect: By providing a material retrieval groove on the inner wall of the sealing ring receiving groove, the cut O-ring rubber seal can be easily removed. By providing a through hole on the positioning rod, the upper mold is moved upward by the handle, which compresses the spring and inserts the load-bearing pin into the through hole to support the upper mold. The rubber plate is placed on the top of the lower mold. After pulling out the load-bearing pin, the handle is held and the upper mold is pressed downward. The spring force pushes the upper mold, increasing its downward pressure, thereby enabling the outer ring cutting blade and the inner ring cutting blade to cut the rubber plate, thus improving the convenience of cutting O-ring rubber seals.

[0010] Preferably, the top of the upper mold is fixed with a handle, and the upper mold has multiple positioning holes.

[0011] Furthermore, the positioning rod is slidably inserted into the positioning hole, and the top end of the positioning rod is fixed with a top plate that abuts against the spring.

[0012] Furthermore, the side wall of the positioning rod is provided with a through hole, and a load-bearing pin for supporting the upper mold is slidably inserted into the through hole.

[0013] Furthermore, a groove is provided at the top of the inner wall of the screw hole, and a material receiving groove is provided on the inner wall of the sealing ring receiving groove.

[0014] Furthermore, the cut-out seat is provided with a connecting groove, and the connecting seat fits into the connecting groove.

[0015] Furthermore, the side wall of the cut-out seat is fitted with a bolt, which passes through the threaded connection of the connecting seat and is fitted with a nut.

[0016] (3) Beneficial effects

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This invention features a base threaded into a screw hole at the top of the upper mold, with a sealing ring receiving groove on the base. Multiple cutting seats are fixed at the bottom of the upper mold. As the lower mold moves downward via the positioning rod, the outer and inner ring cutting blades on the connecting seat cut the rubber plate placed at the top of the upper mold. During the cutting process, the rubber ring is squeezed into the sealing ring receiving groove, facilitating simultaneous cutting of the outer and inner rings of the rubber ring. This avoids errors caused by cutting the inner and outer rings separately, resulting in rubber ring breakage, and improves the cutting effect of the O-ring rubber seal.

[0019] By providing a material retrieval groove on the inner wall of the sealing ring receiving groove, the cut O-ring rubber seal can be easily removed. By providing a through hole on the positioning rod, when the upper mold is moved upward by the handle, the spring is squeezed, and the load-bearing pin is inserted into the through hole to support the upper mold. The rubber plate is placed on the top of the lower mold. After pulling out the load-bearing pin, the handle is held and the upper mold is squeezed downward. The elastic force of the spring pushes the upper mold to increase its downward pressure, thereby enabling the outer ring cutting blade and the inner ring cutting blade to cut the rubber plate, thus improving the convenience of cutting O-ring rubber seals.

[0026] 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.

[0027] This specific embodiment is an O-type rubber sealing notch mold, the structural diagram of which is shown below. Figure 1 and Figure 2 As shown, the O-type rubber sealing cut mold includes a lower mold 1 and an upper mold 7 disposed above the lower mold 1. The top of the lower mold 1 has multiple screw holes 2, and the top of the lower mold 1 is fixed with a positioning rod 3 inserted into the upper mold 7. The top of the positioning rod 3 is fitted with a spring 4 that abuts against the upper mold 7. A base 12 is threaded into the screw holes 2. The top of the base 12 has a sealing ring receiving groove 13. The bottom of the lower mold 1 is fixed with a cut seat 15, and a connecting seat 17 is fixed on the cut seat 15. The bottom of the connecting seat 17 is fixed with an inner ring cutting blade 19 and an outer ring cutting blade 18, respectively.

[0028] A handle 6 is fixed to the top of the upper mold 7, and multiple positioning holes 5 are provided on the upper mold 7. The positioning rod 3 is slidably inserted into the positioning hole 5, and a top plate 8 that abuts against the spring 4 is fixed to the top of the positioning rod 3. A through hole 10 is provided on the side wall of the positioning rod 3, and a load-bearing pin 9 for supporting the upper mold 7 is slidably inserted into the through hole 10. During the downward movement of the lower mold 1 by the positioning rod 3, the outer ring cutting blade 18 and the inner ring cutting blade 19 on the connecting seat 17 cut the rubber plate placed at the top of the upper mold 7, and squeeze the rubber ring into the sealing ring receiving groove 13 during the cutting process. This facilitates the simultaneous cutting of the outer and inner rings of the rubber ring, avoiding the situation of rubber ring breakage due to errors caused by cutting the inner and outer rings separately.

[0029] like Figure 3 and Figure 4As shown, a groove 11 is provided at the top of the inner wall of the screw hole 2, a material taking groove 14 is provided on the inner wall of the sealing ring receiving groove 13, a connecting groove 20 is provided on the cutting seat 15, and the connecting seat 17 is fitted into the connecting groove 20. A bolt 16 is installed on the side wall of the cutting seat 15, and the bolt 16 passes through the connecting seat 17 and is threaded with a nut. When the handle 6 moves the upper mold 7 upward, it compresses the spring 4 and inserts the load-bearing pin 9 into the through hole 10 to support the upper mold 7. The rubber plate is placed on the top of the lower mold 1. After pulling out the load-bearing pin 9, the handle 6 is held and the upper mold 7 is pressed downward. The elastic force of the spring 4 pushes the upper mold 7 to increase its downward pressure, thereby causing the outer ring cutting blade 18 and the inner ring cutting blade 19 to cut the rubber plate.

[0030] The O-ring rubber sealing cut mold Figure 1 An enlarged schematic diagram of the structure at point A is shown below. Figure 2 As shown, the structural schematic diagram of the upper mold 7 is as follows: Figure 3 As shown, the cross-sectional view of the lower mold 1 is as follows. Figure 4 As shown.

[0031] Working principle: When using the device of this technical solution, when the handle 6 is held and the upper mold 7 is moved upward, the spring 4 is squeezed. The load-bearing pin 9 is inserted into the through hole 10 to support the upper mold 7. The rubber plate is placed on the top of the lower mold 1. After the load-bearing pin 9 is pulled out, the handle 6 is held and the upper mold 7 is squeezed downward. The elastic force of the spring 4 pushes the upper mold 7 to increase its downward pressure, so that the outer ring cutting blade 18 and the inner ring cutting blade 19 cut the rubber plate. During the downward movement of the lower mold 1 through the positioning rod 3, the outer ring cutting blade 18 and the inner ring cutting blade 19 on the connecting seat 17 cut the rubber plate placed on the top of the upper mold 7. During the cutting process, the rubber ring is squeezed into the sealing ring receiving groove 13, which facilitates the simultaneous cutting of the outer and inner rings of the rubber ring. This avoids the error caused by cutting the inner and outer rings separately, which may lead to the breakage of the rubber ring, and improves the cutting effect of the O-ring rubber seal.
