Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a rubber oil seal injection mold. Background Technology

[0002] Oil seal is a common term for general sealing components. Simply put, it is a seal for lubricating oil. It is used to seal grease, which is the most common liquid substance in transmission systems. It also refers to mechanical components that are generally liquid substances. It isolates the lubricated parts from the output parts in the transmission components to prevent the lubricating oil from leaking. Static seals and dynamic seals are generally used for reciprocating motion.

[0003] Existing oil seals require molds during production, and these molds are designed for assembly. During the cooling process, improper operation can cause material to adhere to the outer surface of the mold. Since existing molds are generally installed in a fixed manner, demolding can sometimes be difficult, and cleaning can also be inconvenient. Utility Model Content

[0004] The purpose of this utility model is to solve the problems of existing molds that are basically installed in a fixed manner, which sometimes makes demolding difficult and causes inconvenience during cleaning. Therefore, a rubber oil seal injection mold is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

A connecting strip is provided between the plurality of second molds on both sides of the partition strip, and the two connecting strips are set to be parallel to the partition strip. An adjustment component is provided between the two connecting strips and the partition strip.

[0007] The adjustment assembly includes a bidirectional screw mounted in the middle of the partition bar via bearings. Both ends of the bidirectional screw are threaded through the two connecting bars. Several limiting rods are provided on both sides of the partition bar, and the limiting rods are all threaded through the two connecting bars. A servo motor is provided on one side of the base, and the output shaft of the servo motor is connected to one end of the bidirectional screw.

[0008] Preferably, there is a gap between the plurality of the limiting rods.

[0009] Preferably, the limiting rods on both sides of the bidirectional screw are arranged symmetrically.

[0010] Preferably, each of the limiting rods has a cavity, one end of each of the limiting rods is threaded with a rotating plug, and an expansion strip is provided on each of the limiting rods.

[0011] Preferably, the orientations of the expansion strips on both sides of the separator are different.

[0012] Preferably, all of the aforementioned limiting rods are made of hard alloy material.

[0013] Preferably, the outer side of each of the limiting rods is provided with a wear-resistant coating.

[0014] The present invention provides a rubber oil seal injection mold with the following advantages: by adjusting the movement of the connecting strip along the component, the spacing between the several second molds and the several first molds can be adjusted, thereby making it easier to demold the rubber oil seal and facilitating the removal of irregularly shaped rubber oil seals.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example 1: Refer to Figure 1-5 A rubber oil sealant injection mold includes a base 1, a partition strip 4 is provided in the middle of the top of the base 1, a plurality of first molds 2 are provided on the base 1 on both sides of the partition strip 4, and there is a gap between the plurality of first molds 2. A plurality of second molds 3 are placed on one side of the plurality of first molds 2, and the plurality of second molds 3 are correspondingly arranged with the plurality of first molds 2. A connecting strip 5 is provided between the plurality of second molds 3 on both sides of the partition strip 4. The two connecting strips 5 and the partition strip 4 are both set to be parallel. An adjustment component is provided between the two connecting strips 5 and the partition strip 4.

[0023] The adjustment assembly includes a bidirectional screw 6 mounted in the middle of the partition bar 4 via bearings. Both ends of the bidirectional screw 6 are threaded through two connecting bars 5. Several limiting rods 7 are provided on both sides of the partition bar 4, and the limiting rods 7 are all threaded through the two connecting bars 5. A servo motor 8 is provided on one side of the base 1, and the output shaft of the servo motor 8 is connected to one end of the bidirectional screw 6.

[0024] By activating the servo motor 8, the output shaft of the servo motor 8 rotates the bidirectional screw 6, causing the two threaded ends of the bidirectional screw 6, along with the two connecting strips 5, to move on the base 1. This allows the several second molds 3 to be in a mating state with the several first molds 2. After rubber is injected into the area between the first molds 2 and the second molds 3, and the rubber oil seal is formed, the servo motor 8 is activated again. The output shaft of the servo motor 8 rotates the bidirectional screw 6, causing the two threaded ends of the bidirectional screw 6, along with the two connecting strips 5, to move on the base 1. This allows the several second molds 3 to be separated from the several first molds 2, making it easier to remove the rubber oil seal. After removing the oil seal, cleaning the residual glue inside the first molds 2 and the second molds 3 is also easier. Thus, during the injection molding process, the molten plastic is first injected into the mold's runner system through the nozzle, and then enters the cavity through the top area of ​​the first molds 2 and the second molds 3. Inside the cavity, the plastic cools and solidifies to form the product. After the injection is completed, the mold needs to be opened, the product removed, and the residual glue in the runner removed, providing the advantage of quick use for the next injection.

[0025] Example 2: An optimization based on Example 1, with reference to... Figure 1-5 There are gaps between several limiting rods 7, and several limiting rods 7 on both sides of the bidirectional screw 6 are arranged symmetrically. Several limiting rods 7 are all made of hard alloy material, and several limiting rods 7 are all provided with wear-resistant coating on the outside.

[0026] By setting the wear-resistant coating on the outer side of several limit rods 7 to be formed by carburizing, the mechanical properties of several limit rods 7 are greatly improved, thereby increasing the strength of several limit rods 7 and making several limit rods 7 less prone to deformation, thus making the device more stable in use.

[0027] Example 3: An optimization based on Examples 1-2, with reference to... Figure 1-5 Each of the limiting rods 7 has a cavity 9 inside, and each of the limiting rods 7 has a rotating plug 10 threaded to one end. Each of the limiting rods 7 has an expansion strip 11, and the orientation of the expansion strips 11 on both sides of the separator 4 is different.

[0028] By setting a cavity 9 and adding hydraulic oil into the cavity 9, and using a torque wrench to rotate the rotating plug 10, the hydraulic oil in the cavity 9 will squeeze the expansion strip 11, causing the outer side of the expansion strip 11 to squeeze the connecting strip 5. Then, the directions of the compression of the expansion strips 11 are different, making the gap between the limiting rods 7 and the connecting strip 5 smaller. At the same time, the limiting rods 7 prevent the connecting strip 5 from shifting, so that when the bidirectional screw 6 rotates in Embodiment 1, the two connecting strips 5 are less likely to shift after moving on the base 1, making the fit between the first molds 2 and the second molds 3 better, thereby improving the quality of the rubber oil seal after molding in Embodiment 1.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
