Description

Eccentric ejection structure of injection mold
Technical Field
The utility model belongs to the technical field of injection mold, what relate to is an injection mold's eccentric ejecting structure.
Background
At present, plastic parts are different in size and complex in modeling, particularly for larger parts, the yield requirement of the parts is not high, a pouring gate cannot be arranged on the surface of the parts, the positions of the pouring gate and an ejection hole are usually eccentric simultaneously, the problems of unbalanced ejection, ejection seizure and high cost caused by eccentric ejection can occur in the actual production and application process, and the problems are solved by an eccentric ejection structure of an injection mold.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a solve eccentric ejecting problem that leads to ejecting uneven, ejecting seizure, with high costs of mould, the utility model provides an injection mold's eccentric ejecting structure, including the bottom plate, be equipped with the fixed block on the bottom plate, it is equipped with the guide arm to rotate on the fixed block, the guide arm top is equipped with thimble panel, thimble panel slides and sets up in the lower mould of mould, be equipped with circular-arc arch on the guide arm, the arch is used for driving thimble panel and removes in the middle of being located thimble panel, the guide arm below still is equipped with the drive guide arm pivoted ejector pin.
Preferably, the protrusion abuts against the ejector pin base plate and keeps line contact with the ejector pin base plate, and the ejector pin base plate is fixedly connected with the ejector pin panel through a bolt. The arc-shaped bulge structure is adopted, so that the arc-shaped bulge is always in line contact with the thimble base plate, and the relative movement cannot be generated.
Furthermore, a mounting groove is formed in the fixing block, one end of the guide rod is rotatably arranged in the mounting groove through the positioning pin, an arc-shaped ejector block is downwards arranged at the other end of the guide rod, and the ejector block is in contact with the ejector rod. The ejector rod pushes the ejector block to move upwards, the ejector rod and the ejector block keep line contact, and relative displacement cannot be generated.
Further, the protrusion is a semi-cylinder.
Has the advantages that: the utility model provides a guide arm is under the effect of injection molding machine ejector pin thrust, and the guide arm is rotatory around the locating pin, and guide arm contact thimble bottom plate makes thimble board upward movement, has overcome the ejecting uneven, ejecting dying, the problem with high costs of stinging that prior art eccentric ejection exists. The technical scheme has the advantages of simple and compact structure, stable operation, safety and reliability.

Detailed Description
As shown in the figure, an injection mold's eccentric ejecting structure, including bottom plate 1, be equipped with fixed block 2 on the bottom plate 1, it is equipped with guide arm 3 to rotate on the fixed block 2, 3 tops of guide arm are equipped with thimble panel 4, thimble panel 4 slides and sets up in the lower mould of mould, be equipped with circular-arc arch 6 on the guide arm 3, arch 6 is the semicolumn, arch 6 is used for driving thimble panel 4 to remove in the middle of being located thimble panel 4, 3 below of guide arm still are equipped with the drive 3 pivoted ejector pins 5 of guide arm. The protrusion 6 abuts against the ejector pin base plate 7 and keeps line contact with the ejector pin base plate 7, and the ejector pin base plate 7 is fixedly connected with the ejector pin panel 4 through a bolt 8. The fixed block 2 is provided with a mounting groove 10, one end of the guide rod 3 is rotatably arranged in the mounting groove 10 through the positioning pin 9, the other end of the guide rod is downwards provided with an arc-shaped ejector block 11, and the ejector block 11 is in contact with the ejector rod 5.
The specific working principle is as follows: one end of the guide rod 3 is rotatably connected with the fixed block 2 through a pin, when the ejection is carried out, the ejector rod 5 of the injection molding machine moves upwards, when the ejector rod 5 of the injection molding machine is contacted with the arc-shaped ejector block 11 of the guide rod 3, the guide rod 3 moves upwards around the positioning pin 9, when the guide rod 3 moves to cause the arc-shaped bulge 6 of the guide rod 3 to be contacted with the ejector bottom plate 7, the ejector bottom plate 7 moves upwards, and a workpiece is ejected out due to the fact that the die cavity is arranged above the ejector. The technical scheme has the advantages of compact structure, stable operation, safety and reliability.
