Summary of the invention
The purpose of the utility model is to provide a kind of type concealed glue inlet structures, should can solve rubber product into plastic structure and exist
Can be in appearance there are into glue point when vulcanizing injection-molded product the problem of.
According to technical solution provided by the utility model, a kind of type concealed glue inlet structure, it is characterized in that: described into plastic structure
The lower end of each runner is set；
It is described into plastic structure include into glue portion, transition part, flow path portion；
Described into glue portion is hollow cylindrical structure, and the outlet of upper end and runner, lower end and transition part upper end connect
It connects,
The transition part is the up big and down small funnel structure of opening, transition part lower end connecting passage portion；
The flow path portion is divided into perpendicular runner and crossing current road；
The perpendicular runner includes that the first perpendicular runner, the second perpendicular runner and third erect runner, and the diameters of three perpendicular runners is from the
One perpendicular runner is incremented by successively to the perpendicular runner of third；
The crossing current road erects runner with third and is arranged in a mutually vertical manner, and the road that flows over is located at third and erects position at the L of runner bottom；
Fillet part transition is set between the two；
The crossing current road includes that flow path portion and arc bend portion, arc bend portion are symmetricly set on runner anyhow anyhow
The both ends in portion, arc bend portion front end are provided with overlap portion, product entrance and lower overlap portion, the product entrance
It is arranged between upper and lower overlap portion.
Further improvement of these options, arc connects between arc bend portion and anyhow flow path portion, and curved angle exists
45°±2°。
Further improvement of these options, product entrance is with a thickness of 0.1mm.
The utility model has the advantage that the utility model service efficiency is high, adjustment is simple, can reduce labour's promotion
Working efficiency is versatile.
Detailed description of the invention
Fig. 1 is the utility model front view.
Fig. 2 is the utility model general assembly view.
Fig. 3 is the utility model arc bend portion view.
Specific embodiment
Below with reference to specific attached drawing, the utility model is described in further detail.
As shown in FIG. 1 to 3,1, a kind of type concealed glue inlet structure, it is characterized in that: described be arranged into plastic structure at each point
The lower end of runner；
It include into glue portion 1, transition part 2, flow path portion into plastic structure；
It is hollow cylindrical structure into glue portion 1, the outlet of upper end and runner 7, lower end and 2 upper end of transition part connect
It connects,
Transition part 2 is the up big and down small funnel structure of opening, transition part lower end connecting passage portion；
Flow path portion is divided into perpendicular runner 4 and crossing current road 5；
Perpendicular runner includes that the first perpendicular runner 4.1, the second perpendicular runner 4.2 and third erect runner 4.3, the diameter of three perpendicular runners
It is incremented by successively that runner is erected from the first perpendicular runner to third；
The crossing current road 5 erects runner 4.3 with third and is arranged in a mutually vertical manner, and the road that flows over is located at third and erects 4.3 bottom L of runner
Locate position；6 transition of fillet part is set between the two；
Fillet part transition is set between the two；Fillet part circle of position angle, it is ensured that sizing material is in the case where minimum shearing friction
It into type chamber, prevents from generating clinker because of frictional heat generation, while having prevented dead glue from occurring.Perpendicular runner bottom opening can guarantee product
Smoothly extract.
The crossing current road 5 includes that flow path portion 5.1 and arc bend portion 5.2, arc bend portion are symmetricly set on anyhow
Anyhow the both ends of flow path portion, arc bend portion front end are provided with overlap portion 5.2a, product entrance 5.2b and lower overlap
Portion 5.2c, the product entrance are arranged between upper and lower overlap portion.
In this way after product depanning, it is next to guarantee that the sizing material of transition part or more can be directly used in transition part for runner fracture
Mould production, the first perpendicular runner the following are clinker, that is, trim together with overlap during can directly trimming later by the waste material generated
Fall.
Further improvement of these options, arc connects between arc bend portion 5.2 and anyhow flow path portion 5.1, arc
Angle is at 45 ° ± 2 °.In 45° angle into glue, this transition into compared with mode not only can guarantee that glue rapidly entered type chamber, but also can be reduced
Frictional heat generation between sizing material and mold.
Further improvement of these options, 5.2b is with a thickness of 0.1mm for product entrance.Both can guarantee product smoothly into
Glue, and trimmed convenient for product, guarantee that product easily tears product overlap very much, and guarantee that product without into glue point, guarantees product
Appearance zero defect.
Specific implementation process: rubber enters after material cylinder preheating from mouth entrance out is filled, and then flows into runner, says from shunting
Enter glue inlet structure after coming, the sizing material entered from glue-feeder position enters product flash locations, finally via product overlap mouth
Type chamber is filled, last sulfidization molding takes out product, tears overlap.
Above embodiment is only illustrative of the principle and efficacy of the utility model, and not for limitation, this is practical new
Type.The utility model can be improved there are many more aspect under the premise of without prejudice to overall thought, for being familiar with this technology
Personage can all be carried out modifications and changes to above-described embodiment under the spirit and scope without prejudice to the utility model.Therefore,
Such as those of ordinary skill in the art is in spirit revealed without departing from the utility model and institute under technical idea
All equivalent modifications or change completed, should be covered by the claim of the utility model.
It should be noted last that the above specific embodiment is only to illustrate the technical solution of the utility model rather than limits
System, although the utility model is described in detail referring to example, those skilled in the art should understand that, it can be right
The technical solution of the utility model is modified or replaced equivalently, without departing from the spirit and model of technical solutions of the utility model
It encloses, should all cover in the scope of the claims of the utility model.
