Description

A kind of Simple And Practical type bullet needle construction of plastic mould

Technical field

The utility model relates to a kind of mould unloading structures of plastic mould, more particularly, to a kind of structure for playing needle depanning.

Background technique

With the development of modernization industry, plastic mould using more and more extensive, in automobile, electronics, instrument and meter, family In the products such as electricity, aerospace, building materials, motor and Communication Equipment, most of components will rely on plastic mould machine-shaping. Plastic mould is usually all that the mode directly pushed up is selected to demould at present.When some plastic products have the position of bone, the mode directly pushed up cannot Normal demoulding, it is necessary to be demoulded using angle ejector rod.Angle ejector rod design is relatively easy, and cost is relatively low.Angle ejector rod is along certain Angle is sideling pushed ahead, and after angle ejector rod a trip forward, the position of bone is just departing from the interior side contacts of plastic cement, to make product It can smoothly take out.But if the position of bone of plastic product is too deep, the position of bone can stick together angle ejector rod, and in the oblique top throw of lever, product can quilt Deformation is drawn, thimble meeting bending leads to scrap of the product.Therefore, it is necessary to improve.

Utility model content

The purpose of this utility model, which is that, provides a kind of Simple And Practical type bullet needle construction of plastic mould, above-mentioned to solve Problem.

The utility model achieves the above object through the following technical schemes:

A kind of Simple And Practical type bullet needle construction of plastic mould, including rear cavity and angle ejector rod, the rear cavity top are left Side is vertical plane；The rear cavity top is equipped with type chamber；The angle ejector rod upper left side is in contact with the type chamber；The rear cavity In be equipped with the inclined top hole for allowing the angle ejector rod to pass through；The angle ejector rod is set in the inclined top hole；The angle ejector rod lower part It is pierced by the rear cavity, further includes playing needle, the bullet needle is embedded in angle ejector rod top；The bullet needle left part is pierced by angle ejector rod, It is contacted with the type chamber, right part is in contact with the vertical plane.

Further, the top of the angle ejector rod is provided with the angle ejector rod groove of opening to the right, and the bullet needle is embedded in institute It states in angle ejector rod groove.

Further, further include spring, play needle plate and play needle limit base；The bullet needle plate is arranged in the middle part of the bullet needle； It is in contact on the right side of the bullet needle plate on the left of bullet needle limit base；The spring pocket is and recessed with the angle ejector rod on the bullet needle Connect on the left of trench bottom and bullet needle plate.

It further, further include thimble, the thimble is in contact through the rear cavity, top with the type chamber.

It further, further include inclined surface, the inclined surface is arranged above the vertical plane, and angle and the bullet needle are right Downside is consistent.

The beneficial effects of the utility model are that structure installation is simple, is provided on angle ejector rod and plays needle, play needle with oblique In the moving process of mandril obliquely, gradually becomes smaller at a distance from rear cavity and be finally in contact.Needle is played due to hanging down in rear cavity The active force faced directly is moved to the left, and is pierced by angle ejector rod to the left, pops up product.It is provided with inclined surface also on angle ejector rod, avoids The interference of bullet needle and rear cavity when mold clamping.The depanning that the plastic product of position of bone depth may be implemented prevents plastic product glutinous Angle ejector rod prevents plastic product from deforming, and prevents thimble bending, reduces product rejection rate.

Specific embodiment

The utility model is described in further detail with reference to the accompanying drawing:

As shown in Figure 1, a kind of Simple And Practical type bullet needle construction of plastic mould, including rear cavity 2 and angle ejector rod 1, it is described 2 upper left-hand of rear cavity is vertical plane 9；2 top of rear cavity is equipped with type chamber；1 upper left side of angle ejector rod and the type chamber It is in contact；The inclined top hole for allowing the angle ejector rod 1 to pass through is equipped in the rear cavity 2；The angle ejector rod 1 is set to the oblique top In hole；1 lower part of angle ejector rod is pierced by the rear cavity 2, further includes playing needle 4, the bullet needle 4 is embedded in 1 top of angle ejector rod；Institute It states bullet 4 left part of needle and is pierced by angle ejector rod 1, contacted with the type chamber, right part is in contact with the vertical plane 9.

It further include thimble 10, the thimble 10 is in contact through the rear cavity 2, top with the type chamber.The top Needle 10 is supplied to the upward active force of product in mold depanning, and the product is helped to take off release chamber.

It further include inclined surface 8, the inclined surface 8 is arranged above the vertical plane 9, angle and 4 lower right side of bullet needle Face is consistent.Angle unanimously ensure that the angle ejector rod in backstroke, and the bullet needle and the rear cavity are interfered.

In said structure, further include spring 5, play needle plate 6 and play needle limit base 7；The bullet needle plate 6 is arranged in the bullet 4 middle part of needle；It is in contact on the left of 6 right side of bullet needle plate and bullet needle limit base 7；5 sets of the spring on the bullet needle 4, and with Connect on the left of the angle ejector rod bottom portion of groove and bullet needle plate 6.

Working principle: after plastic mould, which goes out die process, to be started, the rear cavity 2 is motionless, the thimble 10 and it is described tiltedly Mandril 1 moves up simultaneously, and moves up with the product.During the angle ejector rod 1 moves up, by institute Stating angle ejector rod 1 is to move obliquely, and the bullet needle 4 follows the angle ejector rod 1 to move obliquely, the bullet needle 4 and the rear mold The distance of benevolence 2 is gradually reduced, and then 4 right end of bullet needle is withstood by the vertical plane 9.The bullet needle 4 is due to the vertical plane 9 Active force under be moved to the left, the bullet needle plate 6 is moved to the left with the bullet needle 4, and squeezes the spring 5, the bullet needle 4 Across 1 left part of angle ejector rod, and pop up the product 3.After popping up the product 3, the angle ejector rod 1 rises to final line Journey, 4 right part of bullet needle is detached from the vertical plane 9 at this time, lose the active force of the vertical plane 9 the spring 5 start to Right rebound drives the bullet needle plate 6 to move right, and the bullet needle 4 follows the bullet needle plate 6 while moving right.When the bullet After needle plate 6 abuts to the bullet needle plate limit base 7, the bullet needle 4 stops movement, and revert to original position, and it is complete that product 3 goes out die process At state is as shown in Figure 3 at this time.

It is completed when mold goes out die process, after taking out the product 3, mold starts mould-closing stroke, and the thimble 10 is to moving down Dynamic, the bullet needle 4 is followed by the angle ejector rod 1 while moving down, since the gradient and the bullet needle 4 of the inclined surface 8 are right The gradient of downside is consistent, and the lower right sides for playing needle 4 smoothly pass through the inclined surface 8 on the way, the final angle ejector rod 1 with The thimble 10 returns to initial position.

The basic principles and main features and advantage of the utility model have been shown and described above.The technical staff of the industry It should be appreciated that the present utility model is not limited to the above embodiments, the above embodiments and description only describe this The principle of utility model, on the premise of not departing from the spirit and scope of the utility model, the utility model also has various change And improvement, these various changes and improvements fall within the scope of the claimed invention.The utility model requires protection scope It is defined by appending claims and equivalents.
