Abstract
The utility model discloses a polyurethane reaction injection molding equipment in plastics industry, comprising a bucket A, a bucket B, a pouring head, metering pumps, a heating device, a mixing device and a purifier; the buckets A and B with double casing are respectively arranged on the two metering pumps, and the heating device installed between the double casing of the buckets is helical heating pipes which are respectively surround the periphery of the inner casings of the buckets A and B. Raw material is uniformly heated by the heating device, is homogeneously mixed by the mixing device and is cleaned by the purifier. The utility model has the advantages of constant temperature holding of the feed liquid, uniform mix of the raw material, no clogging of the mixing head, high rate of finished products, simple structure, convenient operation, etc; in addition, the utility model can be widely used for producing various soft, semi-hard and hard polyurethane manufactured products and various high and slow rebound polyurethane products.
Description
Technical field
The utility model relates to the former that uses on a kind of plastics industry, specifically, relates to a kind of polyurethane low pressure reaction injection forming equipment.
Background technology
The polyurethane reaction product molding is to finish moulding process by means of chemical reaction in die cavity, and the mould pressure-bearing is little, and required clamp force is little, very remarkable to complex-shaped, thin-walled, its superiority in economy of massive article especially, therefore be widely used in the various parts of various industries, as vehicle steering, instrument board, inside gadget, cushion, cleaner, hard heat-insulated filled articles, sole, indoor decoration line plate, high resilience, slow resilience and various hard polyurethane fat toys etc.Existing polyurethane reaction former is to comprise two batch cans mostly, pouring head, measuring pump and the feed-line that various parts are coupled together, deposit two kinds of pre-configured component fluids raw materials at two batch cans respectively during use, and after heating respectively, thereby two kinds of components are mixed the generation chemical reaction make mutually deserved polyurethane product in die cavity, existing polyurethane reaction former ubiquity raw material heating is insufficient, two kinds of components are mixed uneven, thereby make raw material reaction incomplete, waste raw material, and in course of reaction because sneaking into of bubble makes the decrease in yield of polyurethane product.
Summary of the invention
Technical problem to be solved in the utility model provides that a kind of feed liquid constant temperature keeps, raw material mixes, mixing head does not stop up yield rate height, and polyurethane reaction injection forming equipment easy to use.
The technical scheme of the utility model technical solution problem is as follows:
A kind of polyurethane reaction injection forming equipment comprises A charging basket, B charging basket, pouring head, measuring pump, and described A charging basket and B charging basket lay respectively at the top of two measuring pumps, it is characterized in that, also comprise heater, mixing arrangement, cleaning device;
Described A charging basket and B charging basket are double-deck charging basket, and described heater is between the double casing of charging basket, and described heater is the helical form heating tube, and described heating tube is looped around the periphery of A charging basket and B charging basket internal layer shell respectively; Make by the helical form heating tube that feed liquid is heated evenly in the charging basket, temperature control is stable.
Described mixing arrangement is positioned at pouring head inside, and the mixing arrangement inlet is connected with A, B charging basket with measuring pump respectively by mother tube; Carry feed liquid by measuring pump, make two kinds of feed liquids of A, B obtain full and uniform mixing in mixing head, hybrid electric motor rotates at a high speed and stirs feed liquid and combine the outside pressure of generation with the pressure of pump, and feed liquid is expelled in the mold cavity, has improved the yield rate of product.
Described cleaning device is connected with pouring head by pipeline.Cleaning device can clean mixing arrangement, by compressed air, cleaning agent is delivered to pouring head mixing arrangement is cleaned, and reaches the purpose of cleaning, to guarantee that mixing arrangement does not stop up behind casting complete.
Workflow of the present utility model is: at first two kinds of pre-configured components (being called for short A, B component) liquid charging stock is added respectively in corresponding A, the B charging basket, be heated to the temperature that requires reaction respectively, send in the pouring head with certain proportioning through measuring pump then, evenly inject mould internal reaction curing molding in the back through the high-speed stirred of mixing arrangement.Start cleaning device then mixing arrangement is cleaned, to guarantee the cleaning of when cast next time mixing arrangement.
By above disclosed technical scheme as seen, the utility model polyurethane reaction injection forming equipment has that feed liquid constant temperature keeps, raw material mixes, mixing head does not stop up, yield rate height, simple in structure, advantage such as easy to operate.It is various soft to be widely used in production, the production of semi-rigid and hard polyurethane ester articles and various high resilience, slow rebound polyurethane product.
