Description
Technical field
This utility model belongs to mould applications, especially a kind of runner flow section king pin for injection mold.
Background technology
Calculated by theoretical property design, it is difficult to ensure that the runner absolute equilibrium of multi-cavity mold, need to be according to actual die trial situation
Each runner flow is adjusted, and this adjustment is comparatively relatively difficult.Especially in the mould of different product common mode, some
When also need to turn to runner necessary not only for the adjustment of runner flow, realize the switching of mould state.Existing skill
In art, there is the king pin chosen for runner direction in mould, but be essentially all dual channel and select the pattern of one, and not
Function with control runner flow.
The content of the invention
The purpose of this utility model is to overcome prior art not enough, there is provided the high use of a kind of simple structure and degree of regulation
In the runner flow section king pin of injection mold.
The technical solution adopted in the utility model is：
A kind of runner flow section king pin for injection mold, including pressing plate and king pin, are provided with pin on pressing plate
Hole, the bottom of coaxial package king pin on pin-and-hole is provided with the groove of more than 3, the radius of the groove at the top of king pin
It is not more than the injection molding channel radius of the king pin place injection mold 11, one of groove is for the stream with injection sprue gate
Road is connected, and remaining groove is for being connected with the die cavity runner of cast product.
And, a bolt is coaxially fixedly mounted with the middle part of the king pin, the water of king pin groove bottom is located at the top of the bolt
On horizontal line, coaxial engagement hex nut at the top of bolt.
This utility model advantage and good effect are：
The runner Flow-rate adjustment king pin that this utility model is provided is realized under mould assembled state and die trial process
In the demand made adjustment is needed for runner flow, the steering of runner is easily realized in the mould of different product common mode, significantly
Efficiency is improve, it is time saving and energy saving, save cost.
Description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is cross-sectional view of the present utility model
Fig. 3 is overlooking the structure diagram of this utility model in injection mold；
Fig. 4 is that this utility model carries out overlooking the structure diagram when Flow-rate adjustment is molded simultaneously to double products；
Fig. 5 be this utility model to single product and meanwhile carry out Flow-rate adjustment be molded when overlooking the structure diagram.
Specific embodiment
Below by accompanying drawing, the utility model is described in further detail in conjunction with specific embodiments, and following examples are simply described
Property, it is not determinate, it is impossible to which protection domain of the present utility model is limited with this.
A kind of runner flow section king pin for injection mold, is shown in Fig. 1～Fig. 3, including pressing plate 6 and king pin 2, in pressure
Pin-and-hole 1 is installed on plate, king pin is fixed on injection mold stream by pressing plate by the bottom of coaxial package king pin on pin-and-hole
The middle part in road or the cross part of multiple runners, are provided with the groove of more than 3 at the top of king pin, and the radius of the groove is not more than
The injection molding channel radius of the king pin place injection mold, one of groove 4 are for being connected with the runner at injection sprue gate
Logical, remaining groove 5 is for being connected with the die cavity runner of cast product.
A bolt 7 is fixedly mounted with the middle part of king pin coaxially, at the top of the bolt on the horizontal line of king pin groove bottom, spiral shell
Coaxial engagement hex nut 3 at the top of bolt, is adjusted the nut by spanner and drives bolt, bolt to drive the king pin being fixedly mounted with which,
Make the groove on king pin corresponding from different runners.
Operation principle of the present utility model is：
When groove is not corresponding with runner, injection fluid may not flow into runner, when groove it is completely corresponding with runner
When, so that runner is flowed into full by the way of, when groove is corresponding with runner dislocation, injection fluid can flow injection fluid
Air stream enter runner, but flow is restricted, thus controlling each flowpath pressure for needing injection, is especially being molded to different product common mode
When, for the injection of multiple products can balance the runner fluid pressure balance of the different die cavities of each flow direction in this way.
In the present embodiment, Fig. 4～5 are seen, groove is 3, the die cavity of injecting products is two 8 and 10, two die cavity difference
It is by the groove connection different from king pin of runner 9, not shown with the runner at injection sprue gate.
Although disclosing embodiment of the present utility model and accompanying drawing for the purpose of illustration, those skilled in the art can be with
Understand：In without departing from this utility model and spirit and scope of the appended claims, various replacements, change and modifications all be can
Can, therefore, scope of the present utility model is not limited to embodiment and accompanying drawing disclosure of that.
