Abstract
The invention discloses a hot runner forming die. The hot runner forming die comprises a spreader plate and a hot runner; the hot runner is fixedly arranged on the spreader plate; the inlet of the hot runner is fixedly provided with an electrical heating rod; the outlet of the hot runner is provided with a hot runner nozzle; the outer wall of the outlet of the hot runner is fixedly sleeved with a cooling jacket; a heat resisting sheet is positioned at the front of the hot runner nozzle; a pipeline is arranged in the cooling jacket; and cooling water is delivered into the pipeline. According to the hot runner forming die, the electrical heating rod is used for heating the inlet of the hot runner so as to ensure that pressure of plastic liquid is increased when the plastic liquid flows into the hot runner and is heated via using the electrical heating rod, injection pressure is increased, short product moulding period is ensured, no condensed raw material is left in the hot runner, raw material is saved, and production efficiency is increased; heat conduction coefficient of the cooling jacket is high, so that heat transmission is realized; temperature is controlled with the cooling water, so that the temperature of plastic liquid sprayed out from the hot runner nozzle is controlled in a certain range, sprue local high temperature is avoided, and product moulding quality is ensured.
Description
Technical field
The present invention relates to a kind of mould, particularly relate to a kind of hot runner molding mould.
Background technology
Existing plastic mould has into adhesive dispenser, have to enter adhesive dispenser temperature not high enough, it causes product after formation, need the waste product raw material condensed residued in runner to take out, waste material, in addition, this enter adhesive dispenser runner longer, cause injection pressure to lose large, molding cycle is long, therefore the efficiency of producing is low; Also have to enter adhesive dispenser temperature very high, use cast gate position localized hyperthermia, cause non-uniform temperature, be easy in sizing material forming process produce defect, as some local shrink, stress trace etc.
Because above-mentioned defect, the design people, actively in addition research and innovation, to founding a kind of hot runner molding mould, make it have more value in industry.
Summary of the invention
For solving the problems of the technologies described above, the object of this invention is to provide one can enhance productivity, and ensures product quality, avoids the hot runner molding mould of waste of material.
A kind of hot runner molding mould that the present invention proposes, comprise flow distribution plate and hot flow path, described hot flow path is logical to be fixedly mounted on described flow distribution plate, it is characterized in that: the porch of described hot flow path is installed with electrically heated rod, the exit of described hot flow path is provided with a hot runner gate, and the outlet outer wall of described hot flow path fixes a sheathed coolant jacket, and a heat shield is located in the front end of described hot runner gate, described coolant jacket inside is provided with pipeline, passes into cooling water in described pipeline.
As a further improvement on the present invention, on described hot runner gate, interference fit connects a sprue bush, and described sprue bush is through described heat shield.
As a further improvement on the present invention, described hot runner gate, heat shield and sprue bush are all arranged in described coolant jacket.
As a further improvement on the present invention, described coolant jacket is provided with water inlet and delivery port.
As a further improvement on the present invention, described pipeline is some layers of annulus line.
As a further improvement on the present invention, the position described hot flow path is connected with described flow distribution plate is installed with sealing ring.
As a further improvement on the present invention, described sprue bush is horn-like.
By such scheme, the present invention at least has the following advantages: utilize electrically heated rod to heat the porch of hot flow path, can ensure that plastic liquid flows into runner pressure after heating rod heating and raises, make injection pressure large, guarantee that the formed product cycle is short, and there will be no raw material to be condensed in runner, save raw material, enhance productivity simultaneously, the good coefficient of heat conduction of coolant jacket is utilized to conduct heat, utilize cooling water to carry out control temperature simultaneously, the temperature of the plastics liquid penetrated in hot runner gate is made to remain on certain scope, thus avoid cast gate localized hyperthermia, ensure forming quality of products.
Above-mentioned explanation is only the general introduction of technical solution of the present invention, in order to better understand technological means of the present invention, and can be implemented according to the content of description, coordinates accompanying drawing to be described in detail as follows below with preferred embodiment of the present invention.
