A kind of space multipoint mode Fast Filling system for large scale plastic product production
Technical field
This utility model is related to injection molding art, and specifically a kind of space multipoint mode for large scale plastic product production is quick
Fill system.
Background technology
Plastic as with low cost, resistance to corrosion is strong, plasticity is good, can with advantageous features such as recyclings,
Widely welcome by people, in recent years, with the continuous development of Polymer Technology, plastic processing being constantly brought forth new ideas and dashing forward
Broken, associated plastic product has penetrated into various industries, widely applies national economy every field.
Injection molding technology can with one-shot forming complex contour, closely knit structure, accurate size, any surface finish plastic
Product;And mould can rapidly adapt to the demand that market is continually changing with quick-replaceable;Simultaneously production efficiency, from
Dynamicization, intelligence degree are high, convenient to realize many good characteristics such as " unmanned " management.Just lead in plastic processing from the day of birth
Domain is popular and is widely used, and is one of very important plastics molding process technology.
Although Plastics Injection Molding Technology has many advantages, because the characteristics of its forming principle and technical process, also making
There is many weakness and limitation in Plastics Injection Molding Technology:
1st, forming quality of products is vulnerable to the impact of the characteristics such as the mobility of raw material, shrinkage factor, thin-wall product difficult forming
Molding is unable to even;In, the plastic member product size of big wall thickness is difficult to control to;It is simultaneously higher to plastic product Structural Design Requirement,
The even forming quality of products of wall unevenness is poor.
2nd, large scale plastic product volume is big, weight is big, needs Fast Filling to fill die cavity, then using higher during molding
Pressure carries out pressurize, just can guarantee that product quality and dimensional accuracy, but regular injection forming technique is subject to board nozzle and mould
The restriction of injection system structure form and size, in process of injection molding, melt is by injector stage nozzle and die casting
During system, the pressure loss is serious, it is impossible to carry out Fast Filling, even die cavity occurs sometimes and is also not filled by filling, but front end
Melt, has begun to the phenomenon of cooled and solidified;The injection pressure for injecting board generation simultaneously cannot effectively be transferred to mold cavity
Rationally effectively pressurize is carried out, so that interiors of products structure, presentation quality, dimensional accuracy are all difficult to reach requirement.Both cannot be complete
The every quality index of plastic product is difficult to ensure that using injection tool parameters configuration again sufficiently.
3rd, manufacture Bulk plastic product, in particularly big moldeed depth chamber, thin wall plastic products when, due to mold cavity it is empty
Between narrow, injected current length than excessive, inject the injection pressure overwhelming majority that board produces and consume and flow filling in melt
During, it is ensured that complete filling and forming quality of products, it is necessary to increase injection pressure and clamp force, the note to injecting board
The configuration requirement for penetrating system and clamping mechanism is relatively high, and waste to a certain extent is formed in configuration, can also increase product
Energy resource consumption during processing.Moreover, as injected current length is than excessive, injection pressure cannot be carried out in die cavity effectively
Transmission, melt forefront pressure rapid decay, the internal pressure near the melt at cast gate position will be far longer than away from cast gate position
Melt internal pressure, product cooling sizing after, can because internal stress distribution it is uneven it is easy generation warpage, deformation even
The phenomenons such as cracking, affect forming quality of products and qualification rate, and then increase consumption of raw materials.
4th, large scale plastic product volume is big, weight is big, and injection, pressurize, cooling cycle are longer, needs shortening each technique ring
In the cycle of section, to reach improve production efficiency, the purpose of production cost, but traditional regular injection forming technique are reduced due to injection
Board nozzle, die casting system and mould cavity inner space etc. aspect restriction, it is difficult to make full use of injection board
The related technical parameter configuration such as injection rate, injection pressure, more cannot play injection board to greatest extent and use potentiality.
The above-mentioned weakness of injection molding technology and limitation greatly constrain injection molding technology further development and
Larger range of application.
