Abstract
The utility model discloses a hot runner moulded die, including flow distribution plate and hot runner, the hot runner leads to fixed mounting on the flow distribution plate, the entrance of hot runner has set firmly electrical heating rod, the exit of hot runner is equipped with a hot runner mouth, a coolant jacket is established to fixed cover on the export outer wall of hot runner, a front end location heat shield of hot runner mouth, the inside pipeline that is equipped with of coolant jacket, the cooling water lets in in the pipeline, utilize the entrance heating of electrical heating rod to the hot runner, can guarantee plastics liquid flow inflow and say that the process heating rod heats the back pressure lifting, the feasible pressure of moulding plastics is big, ensure that product molding cycle is short, and do not have again the raw materials to condense in the runner, raw material saving, improve production efficiency simultaneously, utilize the better coefficient of heat -transfer of coolant jacket to conduct heat, utilize the cooling water to come the controlled temperature simultaneously, the temperature that makes the plastics liquid that jets out in the hot runner mouth keeps in certain scope, thereby avoid the local high temperature of runner, guarantee product shaping quality.
Description
Technical field
The utility model relates to a kind of mould, particularly relates 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.
Utility model content
For solving the problems of the technologies described above, the purpose of this utility model is to provide one and can enhances productivity, and ensures product quality, avoids the hot runner molding mould of waste of material.
A kind of hot runner molding mould that the utility model 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 further improvement of the utility model, on described hot runner gate, interference fit connects a sprue bush, and described sprue bush is through described heat shield.
As further improvement of the utility model, described hot runner gate, heat shield and sprue bush are all arranged in described coolant jacket.
As further improvement of the utility model, described coolant jacket is provided with water inlet and delivery port.
As further improvement of the utility model, described pipeline is some layers of annulus line.
As further improvement of the utility model, the position that described hot flow path is connected with described flow distribution plate is installed with sealing ring.
As further improvement of the utility model, described sprue bush is horn-like.
By such scheme, the utility model 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 solutions of the utility model, in order to better understand technological means of the present utility model, 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 utility model.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of hot runner molding mould of the utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
Embodiment: a kind of hot runner molding mould, comprise flow distribution plate 1 and hot flow path 2, described hot flow path is logical to be fixedly mounted on described flow distribution plate, the porch of described hot flow path is installed with electrically heated rod 3, the exit of described hot flow path is provided with a hot runner gate 4, the outlet outer wall of described hot flow path is fixed a sheathed coolant jacket 5, and a heat shield 6 is located in the front end of described hot runner gate, described coolant jacket inside is provided with pipeline 7, passes into cooling water in described pipeline.Electrically heated rod is utilized 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, make the temperature of the plastics liquid penetrated in hot runner gate remain on certain scope, thus avoid cast gate localized hyperthermia, ensure forming quality of products.
On described hot runner gate, interference fit connects a sprue bush 8, and described sprue bush is through described heat shield.Plastic liquid is penetrated by hot runner gate, flow in mould through sprue bush.
Described hot runner gate, heat shield and sprue bush are all arranged in described coolant jacket.Can ensure like this to be cooled into cast gate, avoid occurring into cast gate the situation that local temperature is too high.
Described coolant jacket is provided with water inlet 10 and delivery port 11.Make cooling fluid in coolant jacket can circulation by water inlet and delivery port, improve cooling effectiveness.
Described pipeline is some layers of annulus line.By the layered design of annulus line, make cooling surface larger, ensure that cast gate local temperature is even.
The position that described hot flow path is connected with described flow distribution plate is installed with sealing ring 9.Prevent plastic liquid from overflowing by sealing ring.
Described sprue bush is horn-like.Trumpet-shaped design can make have more plastic liquid to enter into mould in the unit interval, enters to water the time, enhances productivity.
The above is only preferred embodiment of the present utility model; be not limited to the utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
