Embodiment Construction

[0031] The invention discloses a front and rear inclined top demoulding mold and a processing method thereof which are suitable for forming and demoulding injection molded parts provided with annular undercut surfaces.

[0032] like figure 1 Shown, a kind of front and rear mold slope top demoulding mold comprises front mold and rear mold, is provided with front mold chute in the described front mold, is movably provided with front mold slope 7 in the described front mold chute, A rear mold chute is provided in the rear mold, and a rear mold slant 9 is movably arranged in the rear mold chute. The front mold slant 7 and the rear mold slant 9 cooperate to complete the molding of the annular undercut surface of the injection molded part.

[0033] The end of the front mold slope top 7 in contact with the bottom of the front mold slope is also provided with a reset assembly for the elastic reset of the front mold slope top 7 .

[0034] The front mold includes a front mold base 1 ,...

Abstract

The invention discloses a front and back mold inclined top release mold. The front and back mold inclined top release mold comprises a front mold and a back mold; a front mold inclined groove is formed in the front mold; a front mold inclined top is movably arranged in the front mold inclined groove; a back mold inclined groove is formed in the back mold; a back mold inclined top is movably arranged in the back mold inclined groove; the inclined directions of the front mold inclined top and the back mold inclined top are opposite; the front mold inclined top and the back mold inclined top are matched to finish molding of an annular inverted surface of an injection molding part; and a return component for elastically returning the front mold inclined top is additionally arranged at one end, contacted with the bottom of the front mold inclined groove, of the front mold inclined top. The front and back mold inclined top release mold is stable in structure, excellent in mechanical logic relation, excellent in use effect and higher in machining precision, can be widely applied to molding and mold release of other similar injection parts, and is higher in application and promotion values.

Description

technical field [0001] The invention relates to a demoulding mold with inclined roof of front and rear molds and a processing method thereof, which is especially suitable for molding and demoulding of injection molding parts provided with annular undercut surfaces, and belongs to the field of injection molding processing. Background technique [0002] With the rapid development of the mold industry and the continuous innovation of technology, when processing different injection molding products, the processing procedures used are also different. [0003] An injection mold is used to produce an injection molded part provided with an annular undercut surface, specifically, an injection molded fixing frame provided with an annular undercut surface applied in the medical field. The injection molded part is composed of two parts, a connecting rod and a bottom bracket. A columnar protruding through hole is arranged in the center of the bottom bracket, and an annular undercut surfa...
