Abstract
The utility model relates to a retainer injection mould core, particularly relates to an engineering plastic retainer injection mould core for a cylindrical roller bearing and belongs to the field of a plastic injection mould. The engineering plastic retainer injection mould core is formed by a movable mould core and a fixed mould core; the movable mould core comprises a movable mould core base, a movable mould core plate and a movable mould core body; the movable mould core base is connected with the movable mould core plate; the movable mould core plate is connected with the movable mould core body, namely the movable mould core plate is located between the movable mould core base and the movable mould core body; an air exhausting channel is arranged between the movable mould core base and the movable mould core plate and also between the movable mould core plate and the movable mould core body; the fixed mould core comprises a fixed mould core base and a fixed mould core plate; the fixed mould core base is connected with the fixed mould core plate; and an air exhausting channel is arranged between the fixed mould core base and the fixed mould core plate.
Description
Technical field
The utility model relates to a kind of retainer injection mold core, specifically relates to a kind of cylinder roller bearing engineering plastics cage injection mold core, and it belongs to the plastics injection mould field.
Background technology
At present, on the structural design of cylinder roller bearing with the engineering plastics cage injection mold core, all adopt monoblock type.Although unitary core is simple in structure, handling ease, but can't design gas extraction system on the core, cause the exhaust performance of mould low, obvious weld bond appears in product, and mechanical performance is not enough, just must offer air discharge duct at mold cavity in order to improve mechanical performance, product just unavoidably produces a large amount of overlaps like this, needs after-treatment, increases the costs such as manpower and materials.Simultaneously, because die venting is bad, plastic melt is filled difficulty, and the product packing is not enough, very easily produces the defectives such as size, outward appearance.
Summary of the invention
In view of the problem that prior art exists, the purpose of this utility model is that a kind of Combined cylindrical roller bearing engineering plastics cage injection mold core will be provided.
To achieve these goals, the technical scheme that the utility model adopts is a kind of cylinder roller bearing engineering plastics cage injection mold core, and it is comprised of dynamic mould core and fixed mold; Described dynamic mould core comprises movable model core print seat, movable model central layer and movable model core body, and the movable model core print seat is connected with the movable model central layer, and the movable model central layer is connected with the movable model core body, and namely the movable model central layer is between movable model core print seat and movable model core body; Be provided with the exhaust passage between movable model core print seat and the movable model central layer, be provided with the exhaust passage between movable model central layer and the movable model core body, described fixed mold comprises fixed mold seat and fixed mold plate, and the fixed mold seat is connected with the fixed mold plate; Be provided with the exhaust passage between fixed mold seat and the fixed mold plate.
The utility model has the advantage of: unitary core is changed to the combined type core; Dynamic mould core changes three parts into by an original part and combines, and designs the exhaust passage between each part; Fixed mold changes two parts into by an original part and combines, and designs the exhaust passage between two; It has not only improved the mechanical performance of product, and the outward appearance of simultaneously also beautifying product is avoided because offering air discharge duct at mold cavity, and produced a large amount of overlaps, needs after-treatment, the problem of the costs such as increase manpower and materials.
