Description

Technical Field

[0001] The utility model relates to the technical field of sealing ring molds, in particular to a 45° O-ring mold. Background Art

[0002] The manufacturing molds of sealing rings generally can be divided into three layers, namely, an upper template, a middle template, and a lower template from top to bottom. The processing process generally includes: the lower template and the middle template are fitted together, and raw materials are added into the cavity formed by the lower template and the middle template; the upper template, the middle template, and the lower template are fitted together, and the raw materials are heated and molded. After the molding is completed, the formed sealing ring will be separated from between the upper template and the lower template following the middle template, and finally, the sealing ring on the middle mold is removed by manual or discharging structure to complete the processing of the sealing ring.

[0003] However, the side walls of the existing sealing rings often have protrusions. For the manufacturing molds of the sealing rings similar to the above in the prior art, it is difficult to demold the sealing rings with protrusions on the surface. It is necessary to apply force manually to deform the sealing rings so that they fall off from the middle mold, resulting in cracks in the demolded products. Summary of the Utility Model

[0005] According to a 45° O-ring mold of the utility model, it includes a base and a mold mechanism arranged above the base. A first mold body is arranged inside the mold mechanism. A second mold body is arranged on the right side of the first mold body. A third mold body is arranged between the first mold body and the second mold body. An active mold opposite to the third mold body is arranged on the right side of the first mold body. A blowing mechanism is arranged on the upper side of the mold mechanism. A through groove that penetrates left and right is arranged at the bottom of the blowing mechanism. A moving groove that extends up and down is connected to the middle of the through groove. A double-sided moving rack is slidably and cooperatively connected inside the moving groove. An electric control telescopic device is fixedly arranged on the top wall of the moving groove. The bottom of the electric control telescopic device is dynamically cooperatively connected with the double-sided moving rack. A first air supply pipe is rotatably and cooperatively connected in the through grooves on the left and right sides of the moving groove. A plurality of equally spaced blowing head components are circumferentially fixedly arranged on the first air supply pipe. An arc-shaped rack meshing with the double-sided moving rack is fixedly arranged on the blowing head component. A high-pressure air nozzle is fixedly arranged on the side of the blowing head component away from the double-sided moving rack. A second air supply pipe is fixedly arranged outside the blowing mechanism. One end of the second air supply pipe is connected and communicated with the first air supply pipe. The other end of the second air supply pipe is connected with an external air supply pump device.

[0006] Further technical solution: A hydraulic telescopic controller is fixedly installed on the left side of the mold mechanism.
