Utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of side gate hot flow path syringe mould.This side gate hot flow path syringe mould gate is hidden, and gate vestiges is little, and stress is little, and molding cycle shortens greatly, and hot flow path is not fragile.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is achieved through the following technical solutions: a kind of side gate hot flow path syringe mould, comprise hot mouth main body, hot mouth and sprue mold insert, the surrounding of described hot mouth main body is evenly distributed with four shaping mold cavity assemblies, each shaping mold cavity assembly comprises interior core and the upper cores setting gradually from top to bottom, lower die, upper impression edge cover and lower impressions edge cover, described interior core is inserted into described upper cores, lower die, in the cavity jointly forming between upper impression edge cover and lower impressions edge cover, in described hot mouth main body, be longitudinally provided with sprue, sprue bottom even is provided with four runners corresponding with described four shaping mold cavity module positions, the exit of each runner is provided with hot mouth, described sprue mold insert is tetragonal body shape, this sprue mold insert is slapped together by two corner blocks, each corner block is provided with an outwardly open semicolumn chamber, the semicolumn chamber of two corner blocks is combined into the cylindrical cavity of sprue mold insert, insert in described cylindrical cavity the bottom of described hot mouth main body, the chamber wall in the semicolumn chamber of described each corner block is provided with two mounting grooves, four hot mouths at runner place one by one correspondence pack in four mounting grooves, the outside of each mounting groove is provided with a gum-injecting port, upper cores, lower die, upper impression edge cover, between lower impressions edge cover and interior core, form syringe die cavity, the inner side of the upper end of described syringe die cavity communicates with the gum-injecting port of described mounting groove.
Further, described interior core comprises cylinder with large diameter cylinder portion, cone cylinder portion, small-diameter circular column casing portion and core bedding frame end from top to bottom successively, described cone cylinder portion inserts in described upper cores, described small-diameter circular column casing portion inserts in the upper impression edge cover of described counterdie Renhe, and described core bedding frame end is inserted in lower impressions edge cover.
The beneficial effects of the utility model are: the cast gate in the utility model side gate hot flow path syringe mould is hot flow path side gate, and gate location is the inner side of the upper end of syringe die cavity, and cast gate is hidden, and gate vestiges is little, and cast gate stress is little.Hot mouth main body is inserted the cylindrical cavity of sprue mold insert, and hot mouth is loaded in the mounting groove of sprue mold insert, thereby sprue mold insert is protected piece as hot flow path, and the hot flow path of injecting glue is protected.When injection moulding, sprue mold insert coordinates with hot mouth, is docked and connected with syringe die cavity, carries out injecting glue; Sprue mold insert and upper cores and lower die can closed butt joints, and preventing from cementing leakage, makes gate vestiges little, and product molding precision is high.In addition, the utility model adopts hot flow path side gate, and due to without cold runner, the pressure loss is little, and injection moulding energy consumption is low, simultaneously without cold runner waste material, save raw material, and without coolant flow channel, molding cycle shortens greatly.
