Abstract
The utility model discloses a novel liquid silica gel sprue pull rod structure, include: a pull rod body; the first connecting portion is in a round table shape and is arranged coaxially with the material pulling rod body, the diameter of a first end face of the first connecting portion is smaller than that of a second end face of the first connecting portion, and the first end face of the first connecting portion is connected with the front end face of the material pulling rod body. The utility model discloses can hold the stub bar when the die sinking to make the stub bar follow and draw the material pole to stay the movable mould part, so that the mouth of a river material breaks away from the front mould, thereby make the mouth of a river material get rid of more easily.
Description
Technical Field
The utility model relates to a mould spare part specifically is a novel liquid silica gel sprue draws material rod structure.
Background
In a liquid injection mold, when the mold is opened, the nozzle material is always adhered to the front mold due to vacuum adsorption or material adhesion, so that the nozzle material is difficult to remove, and the production efficiency is influenced.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a novel liquid silicone rubber sprue draws material pole structure is provided, it can be withheld the stub bar when the die sinking to make the stub bar follow and draw the material pole to stay the movable mould part, so that the mouth of a river material breaks away from the front mould, thereby make mouth of a river material get rid of more easily.
In order to solve the technical problem, the utility model provides a novel liquid silicone rubber sprue draws material rod structure, include:
a pull rod body;
the first connecting portion is in a round table shape and is arranged coaxially with the material pulling rod body, the diameter of a first end face of the first connecting portion is smaller than that of a second end face of the first connecting portion, and the first end face of the first connecting portion is connected with the front end face of the material pulling rod body.
Preferably, the side wall of the first connecting portion forms an included angle a with the second end surface of the first connecting portion, and the included angle a is between 60 degrees and 80 degrees.
Preferably, the rear end of the material pulling rod body is also provided with a second connecting part, the second connecting part and the material pulling rod body are arranged coaxially, and the diameter of the second connecting part is larger than that of the material pulling rod body.
After the structure more than adopting, compared with the prior art, the utility model, have following advantage:
the utility model discloses a draw material rod structure is provided with first connecting portion at the front end of drawing the material pole body, because first connecting portion are round platform shape, like this, draw the material pole to be connected with the stub bar through first connecting portion, when the die sinking, draw the material pole to pull the stub bar, make the stub bar follow and draw the material pole to stay the movable mould part, so that the mouth of a river material breaks away from the front mould, then remove the stub bar through artifical or manipulator, so that the mouth of a river material is got rid of more easily, like this, the utility model discloses make mould production efficiency higher.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 2 and 3, the material pulling rod structure of the main flow channel of liquid silicone rubber of the present invention includes a material pulling rod body 10, a first connecting portion 20 and a second connecting portion 30.
The material pulling rod body 10 is cylindrical.
The first connecting portion 20 is in a circular truncated cone shape and is arranged coaxially with the material pulling rod body 10, the diameter of a first end face of the first connecting portion 20 is smaller than that of a second end face, and the first end face of the first connecting portion 20 is connected with the front end face of the material pulling rod body 10.
The lateral wall of the first connecting portion 20 and the second end face of the first connecting portion 20 form an included angle a, the included angle a is between 60 degrees and 80 degrees, preferably, the included angle a is 75 degrees, so that it is easy to separate the stub bar from the material pulling rod.
The second connecting portion 30 is arranged at the rear end of the material pulling rod body 10, the second connecting portion 30 and the material pulling rod body 10 are coaxially arranged, the second connecting portion 30 is disc-shaped, and the diameter of the second connecting portion 30 is larger than that of the material pulling rod body 10.
The material pulling rod body 10, the first connecting portion 20 and the second connecting portion 30 are integrally formed.
As shown in fig. 1, when the front mold 40 and the movable mold 50 are closed, the first connecting portion 20 of the material pulling rod is inserted into the end of the stub bar 60, so that when the mold is opened, the material pulling rod can pull the stub bar 60, so that the stub bar 60 is left in the movable mold 50 along with the material pulling rod, so that the nozzle material is separated from the front mold 40, and then the stub bar 60 is removed manually or by a manipulator.
Preferably, a push rod is axially movably arranged in the material pulling rod, the push rod sequentially penetrates through the second connecting part 30, the material pulling rod body 10 and the first connecting part 20, and the stub bar can be separated from the material pulling rod by axially extending the push rod forwards.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention, but should not be construed as limiting the claims, and the present invention is not limited to the above-described embodiments, but may be modified in various ways. In summary, all changes that can be made within the scope of the independent claims of the present invention are within the scope of the present invention.
