Tool.Injection molding is a kind of processing method used when producing certain complex-shaped components in batches.It refers specifically to melt heated
Plastics by injection molding machine high pressure inject die cavity obtain formed products after cooling and solidifying.Current injection mold, product normally push up
In the case of clamping oblique top or other thimbles when out, product is not easily to fall off.Smoothly to be taken off convenient for the plastic product of special construction
Mould, injection mold can generally use secondary ejecting mechanism, and ejection movement ejects plastic product from die cavity in two times,
To reduce thimble stress, mold generally can be using secondary ejecting mechanism in two times by the biggish product of part enclasping force
It is ejected from die cavity, i.e., after push plate and thimble eject a distance simultaneously, thimble then continues to ejecting product, existing secondary top
Mechanism generally comprises the secondary ejecting mechanism and spring secondary ejection mechanism using lever principle out, however, existing secondary
Ejecting mechanism haves the defects that the disadvantages of many, such as structure is complicated, installation trouble in the actual use process.
Utility model content
The purpose of this utility model is to provide a kind of secondary ejection mechanism for mold, to solve to propose in above-mentioned background technique
The problem of.
To achieve the above object, the utility model provides the following technical solutions:
A kind of secondary ejection mechanism for mold, including guide pad offer sliding slot on the guide pad, are equipped in the sliding slot
Push rod, the push rod are slidably connected with guide pad, and the top of the push rod is fixedly connected with hardboard, the side sliding of the guide pad
Bullet block is connected, the side that bullet block is located on the guide pad is equipped with gradient face.
As a further solution of the present invention: the bottom end of the push rod side is fixedly connected with the first bolt.
As a further solution of the present invention: the side of the guide pad is fixed with the second bolt.
As a further solution of the present invention: the bullet block is fixed with oil cylinder far from the side of guide pad.
As a further solution of the present invention: first bolt is fixedly connected with the ejector retainner plate on extraneous mold.
As a further solution of the present invention: second bolt is fixedly connected with extraneous mold.
As a further solution of the present invention: the two sides on the bullet block positioned at oil cylinder are fixed with buffering elastic
Spring.
Compared with prior art, the utility model has the beneficial effects that the utility model passes through setting push rod and bullet block, energy
It is enough that Double-ejection is carried out to the biggish product of part enclasping force during mould ejection, and only need to be on the basis of common die
This plug-in mechanism does not change original mould structure substantially, and the utility model structure is simple, and part is few, and easy processing is easily installed,
It disassembles and maintains.
