Slide molds can incorporate a variety of shapes into the product form.
However, during molding, injection pressure is also applied to the slide surface, so if the pressure-receiving area is large
Sometimes cracks appear on the slide.
Even if it is made of metal, the effect of repetitive loads in the molding cycle is very
Even if it is made of metal, the effect of repetitive loads during the molding cycle is very significant.
As a countermeasure, the pressure-sensitive area of the slide should be made as small as possible, and the corners should be reinforced with
It is recommended to make the pressure-sensitive area of the slide as small as possible and to make the corner part R to reinforce it.
Cautions for Slide Cores
(1) When using slide cores, it is likely that inclined pins are used.
(1) In principle, the inclination angle of the pin should be 25° or less and the angle of the contact surface of the locking block should be 2°.
In principle, the pin inclination angle should be 25° or less and the locking block contact angle should be 2°. In addition, when the slide operating volume is large, an inclined cam should be used.
In addition, air or hydraulic cylinders may be used.
(2) When the H of the slide core is large, galling causes poor movement and finger pin
It is recommended that ℓ/H be at least 2.
