Description

TECHNICAL FIELD

[0001] The utility model relates to a mould especially a saving type rubber transfer mould. BACKGROUND

[0002] The basic structure of the transfer mould can refer to a rubber flat plate transfer mould in Chinese patent 201020645377.X, which comprises an injection plug plate, an upper mould plate, a middle mould plate, a lower mould plate and a mould cavity, the upper mould plate is clamped at the lower end of the injection plug plate, the middle mould plate is arranged at the lower end of the upper mould plate, the lower mould plate is arranged at the lower end of the middle mould plate, the mould cavity is arranged in the upper mould plate, the middle mould plate and the lower mould plate, guide pillar and guide sleeve are used to connect between the mould plates, and one end of the middle mould plate is in clearance fit with the mould cavity.

[0003] Although the above technical scheme is not recorded in the text, but according to the common knowledge, the vulcanization temperature of rubber is at least higher than 145 DEG C, and the upper mould plate must have a heating structure with a heating temperature higher than 145 DEG C. In addition, according to the common knowledge, the vulcanization of rubber is irreversible. That is to say, the above technical scheme has a defect: the mixing rubber put into the upper mould plate will be vulcanized even if it is not extruded into the cavity, and the vulcanized rubber must be removed before the next injection, which causes a large amount of waste of mixing rubber. SUMMARY

[0004] In view of the defects of the prior art, the utility model provides a saving type rubber transfer mould.

[0005] The technical scheme of the utility model is:

[0006] A saving type rubber transfer mould, which comprises a cover plate, a material carrying plate, a heat insulation plate and a forming plate, the cover plate is connected with the material carrying plate through a guide shaft, the material carrying plate is formed with a material groove, the cover plate is provided with a pressing table corresponding to the material groove, the lower end surface of the material carrying plate is provided with the heat insulation plate, the material carrying plate is connected with the forming plate through a guide shaft, a plurality of cavities are arranged on the forming plate, and the heat insulation plate is provided with a through hole corresponding to each cavity.

[0007] In one preferred embodiment of the present disclosure, the side of the material carrying plate is provided with an injection hole for injecting mixing rubber.

[0008] In one preferred embodiment of the present disclosure, the lower part of the material groove is provided with a limiting flange for preventing the pressing table from contacting the heat insulation plate.

[0009] In one preferred embodiment of the present disclosure, a bottom plate is arranged below the material carrying plate, and the bottom plate is provided with a base for providing support for the mould.

[0010] In a preferred embodiment of the present disclosure, the bottom plate is provided with a heat exchange mechanism corresponding to each cavity, which is used to heat the cavity after the rubber mix is ​​introduced into the cavity, so as to facilitate the vulcanization molding of the rubber mix in the cavity.

[0011] Beneficial effects of the utility model

[0012] According to the present disclosure, after the rubber mix is ​​fed into the trough, it is protected by the heat insulation plate and will not be vulcanized on a large scale due to the high temperature of the molding plate. Therefore, the trough can become a safe temporary storage place for the rubber mix, and the staff does not need to accurately calculate the feeding amount; the content can be fed into the mold cavity through the downward pressure of the cover plate and the press table. After the injection molding is completed, if there is still rubber mix left in the trough, it can be taken out and kept for other uses. It will not be scrapped due to vulcanization, saving production costs. BRIEF DESCRIPTION OF THE DRAWINGS
