Abstract
The invention discloses a feeding system of a plastic water pipe joint mould, comprising a mould cavity and a mould core. The mould cavity and the mould core form a die cavity, the mould cavity is provided with a main channel, one end of the main channel is connected with a nozzle of an injection molding machine, and the other end of the main channel is communicated with the die cavity through a sub- channel and a feeding port of the die cavity. The feeding system is characterized in that the feeding port of the die cavity is arranged on the side wall of the mould core, and the sub-channel enters the die cavity through the feeding port of the die cavity on the side wall of the mould core by penetrating through the mould core. Compared with the prior art, in the scheme, the feeding port of the die cavity is arranged on the side wall of the mould core, the sub-channel which is communicated with the feeding port of the die cavity also penetrates through the interior of the mould core, and freezing materials in the feeding port and the sub-channel after being formed are left on the inside wall of a product (a water pipe joint). The freezing materials automatically snap during demoulding, and the appearance of the product cannot be influenced because a drawing mark falls on the inside wall of the product.
Description
Technical field
The present invention relates to mould of plastics, particularly relate to the feed system of plastic water pipe joint mould, mainly be applicable to single socket joint plastic water pipe joints such as straight-through, threeway, four-way.
Background technology
Because plastic shaping is fast, easy to process, so plastic water pipe joint is used widely.Mould is one of factor that directly influences the plastic water pipe joint quality, the pipe fitting mould mainly comprises die cavity (comprising dynamic model die cavity and cover half die cavity), core, cooling system, ejection system and feed system, die cavity and core constitute die cavity, be moulded products in the die cavity, die cavity is shaped on sprue, a connection injection machine of sprue nozzle, the other end is through runner, the die cavity charging aperture is communicated with die cavity, for the ease of the demoulding, generally the die cavity charging aperture is located on the die cavity, but the shortcoming of its existence is: behind the product molding, ejection system is broken and is coagulated material, and mark of break drops on the outer surface of goods, influenced product appearance thus, and form weld bond and runner limit (because material causes the runner limit to its impact for a long time) easily, mould strength is low, is easy to generate overlap, particularly large-scale water pipe goods, because charging aperture is big, behind the removal charging aperture, the charging aperture vestige is bigger.
Summary of the invention
The objective of the invention is provides a kind of production efficiency height in order to overcome the shortcoming that prior art exists, and moulding is fast, and does not influence the feed system of the plastic water pipe joint mould of products appearance.
The technical scheme of the feed system of plastic water pipe joint mould of the present invention is: comprise die cavity and core, die cavity and core constitute die cavity, die cavity is shaped on sprue, a connection injection machine of sprue nozzle, the other end is communicated with die cavity through runner, die cavity charging aperture, it is characterized in that described die cavity charging aperture on the core sidewall, runner passes core and enters die cavity from the die cavity charging aperture of core sidewall.
The feed system of plastic water pipe joint mould of the present invention, compared with the prior art, it mainly is the position that changes the die cavity charging aperture, the die cavity charging aperture is located at the core sidewall, and also pass from core inside with the runner of die cavity feeding inlet, the material that coagulates after the moulding in charging aperture and the runner is stayed the inwall of goods (water pipe head), coagulates material during the demoulding and is broken automatically, owing to draw trace to drop on the goods inwall, thereby can not influence products appearance.
The feed system of plastic water pipe joint mould of the present invention, its described die cavity charging aperture be one or two or more than two, the quantity of die cavity charging aperture and shape of products and size are relevant, charging aperture is many more, molten plastic flows is fast more, and shaping efficiency is high more.Its described core is a whole core, and whole core is shaped on the runner that tiltedly advances from end face, and runner is communicated with the die cavity charging aperture of core sidewall, and whole core need not to install.Its described core is fixedly formed by the main core and the split of inserting, and the die cavity charging aperture is made the core split built in the sidewall of inserting, and helps the runner processing and the runner demoulding, and convenient maintenance and replacement.Its described inserting is more than one or two or three or three.

The specific embodiment
The invention discloses a kind of feed system of plastic water pipe joint mould, be one to go out four water pipe joint mould as shown in Figure 1, by die cavity 1, core, cooling system, ejection system and feed system are formed, die cavity comprises dynamic model die cavity and cover half die cavity (the die cavity dimidiation of pipe fitting mould, half is fixed, second half moves, this is the needs of the demoulding), die cavity 1 and core constitute die cavity 3, when filling with molten plastic in the die cavity 3, be shaped to goods 8, die cavity 1 is shaped on sprue 11, a connection injection machine of sprue nozzle, the other end is through runner, the die cavity charging aperture is communicated with die cavity 3, it is characterized in that described die cavity charging aperture 4 on the core sidewall, and runner passes core and enters die cavity 3 from the die cavity charging aperture 4 of core sidewall.Compared with the prior art, the feed system of this programme mainly is the position that changes the die cavity charging aperture, the die cavity charging aperture is located at the core sidewall, and the runner that communicates with die cavity charging aperture 4 also passes from core inside, the material that coagulates after the moulding in charging aperture and the runner is stayed the inwall of goods (water pipe head), coagulate material during the demoulding and broken automatically, owing to draw trace to drop on the goods inwall, thus can not influence products appearance.Its described die cavity charging aperture 4 be one or two or more than two, the quantity of die cavity charging aperture is main relevant with shape of products complexity and goods size, and charging aperture is many more, molten plastic flows is fast more, shaping efficiency is high more, shown in Figure 4 is a die cavity charging aperture, and shown in Figure 5 is two die cavity charging apertures.Its described core is a whole core, and whole core is shaped on the runner that tiltedly advances from end face, and runner is communicated with the die cavity charging aperture 4 of core sidewall, and core is integrally manufactured, need not to install.But in actual production process, the processing and the demoulding of runner for convenience, and be convenient to maintain and replace, and the core split can be made, promptly make main core 21 and insert, open molding chamber charging aperture 4 and runner on inserting, again main core 21 is fastened with inserting.It is inserted and also can be made into an integral body, and fixing again after perhaps being divided into polylith and making, inserting as shown in Figure 3 is that integral body inserts 22, and the integral body sidewall of inserting is shaped on die cavity charging aperture 4, and die cavity charging aperture 4 communicates with the oblique runner first 51 that 22 end faces of inserting from integral body enter; As shown in Figure 2 insert by on insert 23 and under insert and 24 form, on the 23 fastening main core 21 of inserting, on insert 23 sidewall be shaped on die cavity charging aperture 4, die cavity charging aperture 4 communicates with the oblique runner second 52 that enters from 23 end faces of inserting; Under insert and 24 insert 23 on fastening, inserting down 24 is shaped on the straight runner 53 that enters from the side, the straight runner 53 formation combined shunting road that communicates with oblique runner second 52.
