1) Under normal circumstances, the ejection distance of the inclined top of the plastic mold is not very long, and it is easy to break. For plastic molds that can realize fully automatic production, the ejection distance of the inclined top can be farther than that of the semi-automatic pick-up. In order to prevent the uneven force when the manipulator picks up the pieces, the force is uneven when picking up the pieces.

2) The angle range of the inclined roof is 3°~15°, and the optimal z range is 3°~8°. When the angle of the inclined roof is greater than 12°, in addition to considering the strength, an auxiliary rod shall be added to prevent the Excessive torque causes the plastic mold lifter to deform and break.

3) The product sticking to the inclined top is the most likely phenomenon in production. The common method is to increase the demolding angle of the product. In the design, excessive ribs on the inclined top of the plastic mold should be avoided.

4) The inclined top rod should not be too thin. For small workpieces, the minimum thickness of the inclined top is 3.00mm, and the thickness of the inclined top is greater than 500.00mm. The thickness of the inclined top should not be less than 25.00mm. Deformation and fracture.

5) The plastic mold lifter is one of the ejector mechanisms, which is used for ejecting products. The area with the lifter at the same position does not need to be put on the top, avoiding the interference between the lifter and the lifter, and the interference between the lifter and the lifter. Simulation verification is required.

6) In injection molding production, I am afraid that the problems encountered are the distortion and deformation of the lifter, and the root is broken. When designing, the slope angle and distance of the lifter of the plastic mold, the material of the lifter, the size of the lifter, and the design of the lifter will affect the sloping roof. Because its own structure is relatively easy to damage, it should be carefully repaired and replaced in injection molding production to avoid hidden dangers such as non-retraction of the front mold sloping top and burrs running on the sloping top.
