Description

Technical Field

[0001] This utility model relates to the field of piston ring casting technology, and in particular to a piston ring casting mold. Background Technology

[0002] A piston ring is a metal ring with a large outward expansion deformation. It is assembled into an annular groove with a corresponding cross-section. The reciprocating and rotating piston ring relies on the pressure difference of gas or liquid to form a seal between the outer surface of the ring and the cylinder, as well as between the ring and one side of the annular groove. Piston rings require the use of casting molds for molding during the casting process.

[0003] Existing piston ring casting molds typically employ a single mold for casting, where a lower mold works in conjunction with an upper mold to complete the casting process. The next filling and material removal operation can only proceed after the entire casting process is finished. This results in poor production continuity, low time utilization, and a long overall production cycle, failing to meet the requirements of high-efficiency production. Therefore, we have introduced a new piston ring casting mold. Utility Model Content

[0004] The main purpose of this invention is to provide a piston ring casting mold that can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A piston ring casting mold includes a casting platform. A groove is formed in the middle of the upper end of the casting platform. Slide grooves are formed at the front and rear of the upper end of the casting platform. An alternating mechanism is slidably connected in both slide grooves. A fixing mechanism is fixedly connected to the upper left and upper right of the alternating mechanism. A lower mold is fixedly installed in each of the two fixing mechanisms. A fixing plate is fixedly connected to the middle of the rear end of the casting platform. An extension plate is fixedly connected to the upper front of the fixing plate. A hydraulic cylinder is fixedly installed at the front upper end of the extension plate. An upper mold is fixedly installed at the output end of the hydraulic cylinder.

[0006] Preferably, the alternation mechanism includes a motor and an alternation platform. A rotating shaft is fixedly installed at the output end of the motor, a gear is fixedly connected to the front end of the rotating shaft, a rack is fixedly connected to the middle of the lower end of the alternation platform, and slide bars are fixedly connected to both the front and rear of the lower end of the alternation platform.

[0007] Preferably, the motor is fixedly mounted on the rear wall of the groove, and the gear is meshed with the rack.

[0008] By adopting the above technical solution: the rotating shaft is driven by a motor to drive the gear to rotate, and the rotational motion is converted into the left and right linear motion of the rack by the meshing of the gear and the rack, thereby realizing the left and right translation of the alternating table.

[0009] Preferably, the alternating platform is located above the casting platform, and the two slide bars are slidably connected to the two slide grooves respectively.

[0010] Preferably, the fixing mechanism includes a fixing ring, four connecting cylinders are fixedly connected to the upper end of the fixing ring, rotating rods are movably connected inside the four connecting cylinders, rotating bars are fixedly connected to the upper ends of the four rotating rods, and fixing bolts are inserted into the upper ends of the four rotating bars.

[0011] Preferably, the lower end of the fixing ring is fixedly connected to the alternating platform, and the fixing ring is located outside the lower mold.

[0012] By adopting the above technical solution, the fixing ring can position the lower mold.

[0013] Preferably, the four rotating bars are arranged in a circular array, and the four fixing bolts all penetrate the lower mold and are connected to the alternating bench threads.

[0014] By adopting the above technical solution, the lower mold can be fixedly installed on the alternating platform using fixing bolts.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The rotating shaft driven by the motor drives the gear to rotate. The meshing of the gear and rack converts the rotational motion into the linear motion of the rack, thereby realizing the left and right translation of the alternating table. This allows the two lower molds on the alternating table to work alternately. When the left lower mold moves to the bottom of the upper mold for casting, the operator can simultaneously fill or remove material from the right lower mold. This avoids the time wasted in the traditional single mold casting process, which requires waiting for the casting to be completed before filling or removing material. It shortens the overall production cycle and improves the efficiency of piston ring casting production. 2. By placing the lower mold inside the fixed ring, rotating the rotating bar towards the lower mold, and using four fixing bolts to fix the lower mold on the alternating platform, not only can the lower mold be positioned and installed, but it is also easy to disassemble the lower mold so as to replace different types of lower molds to adapt to the production of piston rings of different specifications or models.

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] Please see Figure 1-4 This utility model provides a technical solution: A piston ring casting mold includes a casting platform 1. A groove 2 is provided in the middle of the upper end of the casting platform 1. Slide grooves 3 are provided in the front and rear of the upper end of the casting platform 1. An alternating mechanism 4 is slidably connected in the two slide grooves 3. A fixing mechanism 5 is fixedly connected to the left and right of the upper end of the alternating mechanism 4. A lower mold 6 is fixedly installed in the two fixing mechanisms 5. A fixing plate 7 is fixedly connected to the middle of the rear end of the casting platform 1. An extension plate 8 is fixedly connected to the upper front end of the fixing plate 7. A hydraulic cylinder 9 is fixedly installed in the front of the upper end of the extension plate 8. An upper mold 10 is fixedly installed at the output end of the hydraulic cylinder 9.

[0022] In this embodiment, the alternation mechanism 4 includes a motor 41 and an alternation platform 42. A rotating shaft 43 is fixedly installed at the output end of the motor 41. A gear 44 is fixedly connected to the front end of the rotating shaft 43. A rack 45 is fixedly connected to the middle of the lower end of the alternation platform 42. Slide bars 46 are fixedly connected to the front and rear of the lower end of the alternation platform 42. The motor 41 is fixedly installed on the rear wall of the groove 2. The gear 44 is meshed with the rack 45. The alternation platform 42 is located above the casting platform 1. The two slide bars 46 are slidably connected to the two slide grooves 3 respectively.

[0023] The above solution involves using a motor 41 to drive a rotating shaft 43, which in turn drives a gear 44 to rotate. The meshing of the gear 44 with a rack 45 converts the rotational motion into the linear motion of the rack 45, thereby enabling the alternating platform 42 to move left and right. This allows the two lower molds 6 on the alternating platform 42 to work alternately. When the left lower mold 6 moves to the area below the upper mold 10 for casting, the operator can simultaneously fill or remove material from the right lower mold 6. This avoids the time wasted in traditional single-mold casting processes where filling or removing material can only be done after casting is completed, shortens the overall production cycle, and improves the efficiency of piston ring casting production.

[0024] In this embodiment, the fixing mechanism 5 includes a fixing ring 51. Four connecting cylinders 52 are fixedly connected to the upper end of the fixing ring 51. Rotating rods 53 are movably connected inside each of the four connecting cylinders 52. Rotating bars 54 are fixedly connected to the upper ends of each of the four rotating rods 53. Fixing bolts 55 are inserted through the upper ends of each of the four rotating bars 54. The lower end of the fixing ring 51 is fixedly connected to the alternating platform 42. The fixing ring 51 is located outside the lower mold 6. The four rotating bars 54 are arranged in a ring array. The four fixing bolts 55 penetrate the lower mold 6 and are threadedly connected to the alternating platform 42.

[0025] The above solution involves placing the lower mold 6 inside the fixed ring 51, rotating the rotating bar 54 towards the lower mold 6, and fixing the lower mold 6 on the alternating table 42 with four fixing bolts 55. This not only enables the positioning and installation of the lower mold 6 but also facilitates its disassembly, allowing for the replacement of different types of lower molds 6 to adapt to the production of piston rings of different specifications or models.

[0026] It should be noted that this utility model is a piston ring casting mold. During use, the lower mold 6 is placed inside the fixed ring 51, and the rotating bar 54 is rotated to face the lower mold 6. Then, with the help of four fixing bolts 55, the lower mold 6 is fixedly installed on the alternating table 42. This enables the positioning and installation of the lower mold 6 and facilitates its disassembly, allowing for the replacement of different types of lower molds 6 to meet the production needs of piston ring casting of different specifications or models. The motor 41 is started, and the motor 41 drives the rotating shaft 43 to rotate. The rotating shaft 43 drives the gear 44 to rotate. The gear 44 meshes with the rack 45, converting the rotational motion into the left and right linear motion of the rack 45, which in turn drives the alternating table 42 to move left and right. In this way, the two lower molds 6 on the alternating table 42 can work alternately. When the left lower mold 6 moves to the bottom of the upper mold 10 for casting, the operator can simultaneously perform filling or material removal operations on the right lower mold 6. This avoids the time wasted in traditional single-mold casting where filling or material removal can only be performed after casting is completed, shortens the overall production cycle, and improves the efficiency of piston ring casting production.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
