Description
Technical field
The utility model relates to a kind of injector syringe mould, particularly a kind of novel full hot flow path syringe mould.
Background technology
What at present domestic traditional multi-cavity syringe mould adopted is the cold runner mould, hot runner mould has just just entered the research and development advanced development, because waste material causes production cost to improve more when producing product, and die manufacturing cost and maintenance cost are very high, can not satisfy the demand that the user saves cost far away.External most advanced level just adopts a mould two chamber hot flow path structures, the square die of the many employings of forming part, such structure makes that the overall dimension of mould is bigger, and needs use dowel hole and taper hole on the high-precision jig grinder processing die, require extremely accurate machine tooling can reach its design accuracy, cost increases relatively, the Mould Machining cycle is long, it advances the glue mode and advances glue for side blow radially, advance the glue point and be distributed in about 5mm position, needle cylinder wall bottom, nozzle flow channel must break-in 90 ° from axially being converted into radially, the pouring pressure loss is big, energy consumption is big, and mould stream inequality easily produces weld mark and influence the product appearance quality at cast gate opposite barrel, and this pouring type also easily causes the product wall unevenness and influences the product inherent quality.In addition, syringe top injection orifice molding structure adopts die cavity top pin structure, and this structure is unfavorable for that exhaust is that secondly more seriously pin hole in core top is easy to wear when matched moulds, thereby directly causes maintenance cost to increase.
The utility model content
The purpose of this utility model is to overcome the shortcoming of prior art, provide that a kind of mould overall dimension is little, cost is low, a kind of novel full hot flow path syringe mould of easy to maintenance, long service life and good product quality, the position by improving gum-injecting port and exhaust mode improve quality inside and outside the product so that best mould distributions to be provided.
The purpose of this utility model is achieved through the following technical solutions: a kind of novel full hot flow path syringe mould, it comprises the cast gate die, die cavity, interior core, throw-out collar, edge shell type die cavity top, die cavity top mold insert and interior core mold insert, the cast gate die cooperates with die cavity and the vertical cavity plate inside that is installed on, the center of die cavity offers runner, the bottom of runner is provided with glue-feeder, the same circumference on the top of die cavity is provided with a plurality of edge shell type die cavities top, the center on edge shell type die cavity top is set with die cavity top mold insert, the below on edge shell type die cavity top is provided with interior core, the top of interior core is gluedd joint into whole with the bottom of interior core mold insert, the top of interior core mold insert cooperates with die cavity top mold insert, the top of interior core is straight tubular, the middle part of interior core is cone barrel, the straight drum part of interior core cooperates with die cavity, the awl tube part of interior core is connected with the inwall of throw-out collar, and the top of throw-out collar and cast gate die are connected, and the inside of interior core is provided with cooling-water duct.
Described cast gate die and die cavity adopt the pin location, and are screwed.
Be symmetrically arranged with at least two die cavity top screwed holes and at least two die cavity top locating holes respectively on the end face on described edge shell type die cavity top.
Described cavity plate is provided with a plurality of die cavities.
The external diameter of described cast gate die is littler than the external diameter of die cavity.
The utlity model has following advantage:
1, the utility model adopts a mould four cavity configurations, be to be provided with in each cast gate die along circumferential equally distributed four interior cores, form four shaping mold cavities, be combined to form the syringe cavity with four edge shell type die cavity tops, die cavity top mold insert, interior core mold inserts respectively again, advance glue by glue-feeder, four products of a die cavity pipe, the energy that consumes reduces more than 40%, and the shaping mold cavity arrangement is compact, and the size of cavity plate reduces.
2, cost hangs down and is mainly reflected in two aspects: be low cost of manufacture on the one hand, and a mould four cavity configuration compactnesses, cavity plate and the employed raw material of cast gate die are few; Be that maintenance cost is low on the other hand, stud with die cavity top mold insert and interior core mold insert respectively at top inner and interior core, edge shell type die cavity top, core in original is transferred to interior core mold insert to the wearing and tearing of die cavity top mold insert to the wearing and tearing on die cavity top, interior core mold insert and die cavity top mold insert volume are little, and maintenance cost is low.
3, a this mould four cavity configurations, the external diameter of cast gate die is littler than the external diameter of die cavity, and the dismounting simple and fast is easy to maintenance.
4, the critical piece wearing and tearing of moulds such as cavity plate, cast gate die, edge shell type die cavity top and interior core are little, and remaining consumable accessory is removable parts, and increase substantially the service life of mould.
5, advance glue point and advance the glue mode and can make in the casting process mould stream evenly, the gas that molding cavity inside forms in casting process is upwards discharged to the air discharge duct on the end face by the steam vent in the edge shell type die cavity top at top from the bottom, thereby avoided defectives such as weld mark, bubble, product size instability, improved the product appearance quality greatly.The glue point that advances of this structure directly advances glue by the bottom, and that has avoided routine advances the defectives such as product wall unevenness that glue causes from sidewall, has improved product quality greatly.
