Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a die-casting mold for a rubber sealing ring. Background Art

[0002] Molds are various tools used in industrial production to produce desired products through methods such as injection molding, blow molding, extrusion, die-casting, forging, smelting, and stamping. In short, molds are tools used to create shaped objects. These tools are composed of various parts, and different molds are made up of different parts. They primarily achieve the desired shape by changing the physical state of the material being molded. They are often called the "mother of industry."

[0003] For example, the die-casting mold for the cylinder piston sealing ring disclosed in the announcement number CN218591560U has the following technical solutions: it includes a bottom plate, a molding drag box is slidably connected in the slide groove, and through holes are respectively provided on both sides of the molding drag box, four support frames are fixedly connected to the bottom of the support frame, a driving mechanism is provided at the bottom of the support frame, the output end of the driving mechanism is transmission-connected to the upper mold, the bottom of the upper mold is fixedly connected with a molding block, and the two sides of the upper mold are fixedly connected with a connecting plate, and the molding drag box is slidably connected in the lower mold and taken out from the slide groove through the molding drag box, so that the formed sealing ring material can be taken out from the lower mold, which makes it convenient to demold the sealing ring, and the water pump provided on the bottom plate and the cooling pipe fixedly connected to the water pump are used to add cooling water by relying on the cooling pipe, so that the sealing ring after die-casting can be cooled, thereby improving the processing efficiency of the sealing ring.

[0004] However, based on the working principle proposed in the above patent, the applicant believes that the above device requires manual placement of the rubber material between the upper mold and the lower mold before vulcanization. Due to the limited space between the upper mold and the lower mold, the operator must operate in a relatively fixed mold structure, which limits the space and angle for placing the rubber material. In addition, the molding drag box needs to be manually separated from the lower mold by the operator, and long-term operation may cause fatigue. At the same time, when the molding drag box is placed again later, its position cannot be accurately controlled.

[0005] Therefore, a die-casting mold for a rubber sealing ring is proposed in response to the above problems. Utility Model Content

[0006] In order to make up for the deficiencies of the prior art, such as the limited operating space and the lack of precise control, the utility model provides a die for die-casting a rubber sealing ring.

[0008] Preferably, columns are fixedly mounted on the four corners of the top of the base plate, and the tops of the columns are threadedly connected to the top plate.

[0009] Preferably, a hydraulic cylinder is fixedly installed at the middle part of the top of the top plate, a telescopic rod is provided at the bottom of the hydraulic cylinder, and the bottom of the telescopic rod is threadedly connected to the upper mold.

[0010] Preferably, a plurality of inner diameter cavities are fixedly mounted on the bottom of the upper die, and a plurality of oil channels are opened inside the upper die.

[0011] Preferably, an oil inlet pipe is fixedly installed on one side of the oil channel, and a return pipe is fixedly installed on the other end of the oil channel.

[0012] Preferably, a shaft sleeve is provided on the surface of the column, and a cooling fan is fixedly mounted on one side of the shaft sleeve.

[0013] The beneficial effects of the utility model are:

[0014] 1. The utility model realizes the function of moving the lower mold through the structural design of the motor, threaded rod, T-shaped slide, connecting ear, and T-shaped clip. As a result, the threaded rod and the connecting ear can drive the lower mold to move horizontally outward, so that the operating area of ​​the top opening of the lower mold is increased, thereby facilitating the subsequent removal of the formed sealing ring and the replacement of the rubber material, thereby solving the problems of limited operating space and lack of precise control.

[0015] 2. The utility model realizes the function of adjusting the height of the upper mold through the setting of the hydraulic cylinder and the telescopic rod, thereby realizing the automatic separation of the upper mold and the lower mold, and at the same time can provide sufficient downward pressure on the upper mold, thereby achieving the purpose of die casting.

[0024] The following is combined with Figure 1-5 To further explain this application,

[0025] The embodiment of the present application discloses a die-casting mold for a rubber sealing ring, including a base plate 1, a block 2 is fixedly installed on the middle part of the top of the base plate 1, a U-shaped groove 3 is provided in the middle part of the top of the block 2, a motor 4 is fixedly installed on the back of the block 2, a threaded rod 5 is provided on the front of the motor 4, T-shaped slide grooves 6 are provided on both sides of the top of the block 2, a lower mold 7 is movably installed on the top of the block 2, a plurality of outer diameter cavities 8 are provided on the top of the lower mold 7, a connecting ear 9 is fixedly installed on one side of the middle part of the bottom of the lower mold 7, and T-shaped clips 10 are fixedly installed on both sides of the bottom of the lower mold 7.

[0026] Reference Figure 1 、 Figure 3 、 Figure 4 The function of moving the lower mold 7 is realized through the structural design of the motor 4, the threaded rod 5, the T-shaped slide 6, the connecting ear 9, and the T-shaped clip 10. As a result, the threaded rod 5 and the connecting ear 9 can drive the lower mold 7 to move horizontally outward, so that the operating area of ​​the top opening of the lower mold 7 is increased, thereby facilitating the subsequent removal of the formed sealing ring and the re-placement of the rubber material.

[0027] Four corners of the top of the bottom plate 1 are fixedly mounted with upright posts 11 , and the tops of the upright posts 11 are threadedly connected to a top plate 12 .

[0028] Reference Figure 1 and Figure 2 The columns 11 facilitate support for the top plate 12 , thereby ensuring the stability of the main body during the operation of the hydraulic cylinder 13 , and the top plate 12 facilitates providing space for placing the hydraulic cylinder 13 .

[0029] A hydraulic cylinder 13 is fixedly mounted on the middle portion of the top of the top plate 12 , a telescopic rod 14 is provided at the bottom of the hydraulic cylinder 13 , and an upper mold 15 is threadedly connected to the bottom of the telescopic rod 14 .

[0030] Reference Figure 1 and Figure 5 The function of adjusting the height of the upper mold 15 is achieved through the hydraulic cylinder 13 and the telescopic rod 14, thereby realizing the automatic separation of the upper mold 15 and the lower mold 7, and at the same time providing sufficient downward pressure on the upper mold 15, thereby achieving the purpose of die casting.

[0031] A plurality of inner diameter cavities 16 are fixedly mounted on the bottom of the upper die 15 , and a plurality of oil passages 17 are opened inside the upper die 15 .

[0032] Reference Figure 2 and Figure 5 The inner diameter cavity 16 is used to cooperate with the outer diameter cavity 8 to provide a temporary storage space for the rubber material. At the same time, it can also provide a limit for the rubber material so that the rubber material can form a sealing ring later. The oil channel 17 is used to temporarily carry the high-temperature oil body so as to heat the upper mold 15, thereby achieving the necessary conditions for providing the rubber material vulcanization.

[0033] An oil inlet pipe 18 is fixedly mounted on one side of the oil passage 17 , and a return pipe 19 is fixedly mounted on the other end of the oil passage 17 .

[0034] Reference Figure 1 、 Figure 2 、 Figure 5 , through the oil inlet pipe 18 and the return pipe 19, an oil circuit is formed to ensure the flow path of the high-temperature oil.

[0035] A shaft sleeve 20 is sleeved on the surface of the column 11 , and a cooling fan 21 is fixedly mounted on one side of the shaft sleeve 20 .

[0036] Reference Figure 1 and Figure 2 The shaft sleeve 20 facilitates positioning of the cooling fan 21 and facilitates subsequent adjustment of the angle of the cooling fan 21. The cooling fan 21 facilitates accelerating the air flow speed and air-cooling the formed sealing ring.

[0037] Working principle: When using this device, the motor 4 drives the threaded rod 5 to rotate, and the threaded rod 5 cooperates with the connecting ear 9 to drive the lower mold 7 to move. During the movement of the lower mold 7, the T-shaped slide 6 cooperates with the T-shaped clip 10 to ensure its stability during the movement. After the threaded rod 5 rotates and moves the lower mold 7 outward, at this time, the lower mold 7 is partially suspended. After the rubber materials are placed in the corresponding outer diameter cavities 8, the motor 4 is reversed to move the lower mold 7 to the initial position, and the hydraulic cylinder 13 is started. The hydraulic cylinder 13 moves through the telescopic rod 14 drives the upper mold 15 to descend, and as the upper mold 15 gradually fits the lower mold 7, the rubber material is pressed by the inner diameter cavity 16. After the rubber material is deformed by pressure, its outer wall is limited by the outer diameter cavity 8, and its inner wall is limited by the inner diameter cavity 16. After the high-temperature oil is introduced into the oil channel 17 through the oil inlet pipe 18, the high-temperature oil is recovered through the return pipe 19. After vulcanization is completed, the upper mold 15 is raised by the hydraulic cylinder 13, and the lower mold 7 is driven to move outward again by the motor 4. During this period, the formed sealing ring is cooled by the cooling fan 21.

[0038] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention as claimed.
