Description
Technical field
The present invention relates to a kind of mould of working of plastics, particularly a kind of quick change module that is used for moulding plastics spare.
Background technology
The moulding of plastic products be unable to do without mould of plastics.The process of injection molding of plastics mould is that thermoplastic or thermosetting plastics are put into barrel, through heat fused, make it to become full-bodied fluid (being called " melt "), with plunger or screw rod as pressurizing tool, make melt inject the die cavity of mould with higher pressure by nozzle, through supercooling, solidification stages, then from mould, deviate from, become plastic products.It is the characteristics of high production rate, high accuracy, high stock utilization and low cost, low energy consumption that the plastic products of producing by the mould manufacturing have " three high two is low ", and consistency of product is good, helps assembling and exchanges.
Research and development of new product produce have very strong ageing, generally all be to provide the qualified samples and the small lot supply of material according to customer demand earlier, so the research and development production of new product requires very high to the time cycle, development time is short more good more, and less demanding in the development debug phase for productivity ratio, only need satisfy the supply of material of enough samples and small lot and get final product.Generally all be to adopt formal multi-imprssion mould tool of the system of throwing or easy monotype cavity mould production at present, adopt the production investment of multi-imprssion mould tool very big, the mould production cycle is long, and is also bigger because of designing the improper update cost that causes; Although and adopt the production of monotype cavity mould can reduce certain production cost and cycle, effect is also not obvious, required guide, the fixture of mould, advances glue spare and die sinking, stripper etc. and all gets duplication of production.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of quick change module that is used for moulding plastics spare.When this quick change module is used for research and development of products, shaped component be can change fast,, research and development demand and market demand satisfied for the quick research and development of product and sample presentation, the small lot supply of material provide the fastest speed with the required different working of plastics of compacted products.
For solving the problems of the technologies described above technical scheme of the present invention: a kind of quick change module that is used for moulding plastics spare.Its formation comprises part of the upper die, part of the lower die and die sinking device three parts, and described part of the upper die mainly is made up of cope match-plate pattern, gate plate, sprue bush and guide pin; The part of the lower die mainly is made up of base plate, fixed head, die case, die, core fixing plate, die mold insert and handle; The die sinking device mainly is made up of lower open die frame, last die sinking frame and branch mould bases; The inner chamber of die case is a turbination, and the profile of die is conical, and the profile conical surface of die matches with the inner cavity surface of die case; The small raft that can change is housed on base plate, the core that can change is housed on core fixing plate; Base plate and fixed head, die case are screwed and connect as one.
The above-mentioned quick change module that is used for moulding plastics spare also is equipped with screw in cope match-plate pattern.
The aforesaid quick change module that is used for moulding plastics spare is equipped with a stop pin in advance at the hanging platform place of core fixing plate.
The aforesaid quick change module that is used for moulding plastics spare, the guide pillar that two diameters do not wait is housed on die case, the guide finger of an anti-rotation is housed on the inner chamber conical surface of die case, on the die joint of die case, alignment pin is housed, 4 half round cut are arranged in the bottom surface of die case.
The aforesaid quick change module that is used for moulding plastics spare, the die inner chamber is quincunx, and is corresponding with the shape of die mold insert; Die mold insert mount is combined into the box-like combination die cavity of lobe with die on die.
The aforesaid quick change module that is used for moulding plastics spare is provided with 4 and is used for the boss ear of the quick mount of die mold insert on die on the die mold insert.
The aforesaid quick change module that is used for moulding plastics spare, on die, be provided with the installing hole of alignment pin and the groove of horizontal opening die when being used for the correcting guide finger and being used for the branch mould bases dividing mould, and be used for changing fast and 4 half slots of fixing needed combination die cavity.
Mentality of designing of the present invention: be according to the formation characteristics of plastics mould and possible molding mode and advance the glue form, part member designs in the mould is become the general form of maximum possible, and enough design spaces to play are reserved in fixed form that profiled member is required and jogger hole position etc., like this, at the manufacturing and designing of different working of plastics the time, only need to change corresponding shaped component and just can produce different working of plastics, reach the purpose of quick production.
Beneficial effect: compared with prior art, the present invention has the following advantages: (1) looks its concrete part shape, manufactures and designs concrete moulding parts by accepting or rejecting the parts in the existing general module, increasing, promptly plastic required working of plastics, and the cycle is short, and cost is low.(2) by changing sprue bush, not only can produce the thermoplastic part, and can produce thermosetting plastics spare.(3) versatility of module is good, and the space of leaving subsequent design manufacturing performance for is big, advances gate form and can change down gate, some cast gate or side gate etc. arbitrarily into.(4) manufacturing cycle very short, change, maintenance is easy.(5) simple, understandable easy to operate, can produce the working of plastics that reaches the design accuracy requirement with cheap cost.
When the present invention is used for research and development of products, can change shaped component fast with the required different working of plastics of compacted products, comprise the plastic part that has inserts,, satisfy research and development demand and market demand for the quick research and development of product and sample presentation, the small lot supply of material provide the fastest speed.Part manufacturing cycle when the present invention can shorten research and development of new product significantly, the risk and the product that reduce significantly in product development cost and the design research and development are changed expense, can provide partial data and experience to use for reference for follow-up part production in enormous quantities required mould design and manufacturing.The present invention is mainly used in the mould molding of the small plastic spare in the dynamo-electric components and parts, the compacting of required small lot working of plastics when being particularly suitable for the product development exploitation.
