Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of sealing ring processing molds, in particular to a rubber plug mold. Background Art
[0002] Since the rubber plug is T-shaped with sealing waves, it is easy to fall into the middle mold, the demoulding force is large, and it is difficult to eject. Forced ejection can easily damage the product. The existing technology solves this problem through a complex mold structure, but the mold processing and product production methods are complicated and the cost is high. There is also a common ejector cylinder that is pressed against the bottom surface of the rubber plug. In actual use, the rubber plug undergoes a large deformation during the ejection process and is squeezed, and the product cannot be ejected quickly and effectively. Utility Model Content
[0003] The utility model aims to improve the deficiencies of the prior art and provide a rubber plug mold which combines a common mold structure with an ejection structure, has low production and use costs, is simple in production method, and has a high yield rate.
[0004] The purpose of the utility model is achieved in this way. A rubber plug mold includes an upper mold, a middle mold with a material cavity and a lower mold, and is characterized in that it also includes an ejection device, wherein an ejection block is arranged on an ejection plate, the ejection block and the ejection plate are perpendicular to each other, and the top of the ejection block is a step column, the top of the step column is used to insert into the bottom hole of the rubber plug to support the rubber plug, and the step surface of the step column is used to contact the bottom surface of the rubber plug and eject the rubber plug.
[0005] In order to further achieve the purpose of the utility model, the diameter of the step surface may be no greater than the bottom diameter of the rubber plug.
[0006] Compared with the prior art, the utility model has the following significant features and positive effects: the utility model combines an ordinary mold structure with a special ejection structure to provide a simple production method. The ejection block is composed of a step column, and the top surface diameter extends into the hole of the rubber plug to support the plug and reduce the deformation of the rubber plug during the ejection process, thereby smoothly ejecting the product and preventing the rubber plug from tearing, falling off and other defects during the ejection process. The utility model is suitable for T-shaped rubber plug products with sealing waves, which are easy to fall into the middle mold and have small holes at the bottom and are difficult to eject.

[0010] The utility model is further described in detail below with reference to the accompanying drawings and embodiments.
[0011] A rubber plug mold, refer to Figure 1 The conventional rubber plug mold is composed of an upper mold 1, a middle mold 2, and a lower mold 3. The material cavity 4 is arranged on the middle mold 2, and also includes an ejection device. Figure 2 The ejection device is an ejection plate 7 and an ejection block 8 assembled together by bolts 9. The ejection plate 7 and the ejection block 8 are perpendicular to each other. The top of the ejection block 8 is a step column. The top column of the step column is used to insert into the bottom hole of the rubber plug 6 to support the rubber plug 6. The step surface of the step column is used to contact the bottom surface of the rubber plug 6 and eject the rubber plug 6. In order to better eject the rubber plug 6, the diameter of the step surface is not greater than the bottom surface diameter of the rubber plug 6.
[0012] When the utility model is used, the middle mold 2 falls on the lower mold 3, and the upper mold 1 is lifted. The rubber blank 5 is first placed in the material cavity 4 of the middle mold 2. The upper mold 1 is tightly closed with the middle mold 2 during the process of mold closing and pressurization, and the rubber plug 6 is formed by vulcanization. Then the upper mold 1 is lifted, the lower mold 3 is withdrawn, and the ejection plate 7 is lifted upward with the ejection block 8 to eject the rubber plug 6 from the middle mold 2. The top of the step column on the upper part of the ejection block 8 will be inserted into the hole under the rubber plug 6 to support the rubber plug 6, reduce deformation, and prevent the rubber plug 6 from tearing, falling off, and other defects during the ejection process. The step surface contacts the bottom surface of the rubber plug 6 and ejects the rubber plug 6.
