Injection molding machine mold is a kind of tool that mainly produces plastic products; at the same time, it also has tools such as precision and easy to damage. Therefore, the injection molding machine injection molding is a kind of processing method that will be used to mass produce more complex parts. In the process of injection molding, we have a little difference in a certain place, it will easily lead to damage to the mold, then injection molding machine mold in the production process will lead to damage to the mold is what? Below, the Guangdong energy-saving injection molding machine will tell you about the cause of mold damage!

Cause of die damage

 (1) Buried at heat: The quenching temperature of the mold is too high or insufficient or the time for tempering is not the same as the time of the temperature, and the time of the quenching method is not well-controlled; these problems occur only after the injection molding machine is used for a period of time. of.

(2) Stamping of stacked material: The material inside the mold overlaps the stamping that the machine continues to continue. This is commonly referred to as peeling of the stripper board.

(3) Obstruction of waste: The blanking hole is not drilled or the dimensions are not correct, the waste material has not come on the bed and has been cleaned, and the punch and the lower template have been damaged.

(4) The drop of the punch: if it is not properly secured or suspended, the screw may be too thin, resulting in insufficient strength or the punch being broken.

(5) Different escape holes: The size and depth of the punch platen is not enough, or the punch is not the same as the peel plate escape part. This is called the stripper plate in the mold is damaged.

(6) Entry of debris: The molded product has been blown but it has been blown back or the parts of the mold have been chipped and dropped, and the protruded mold face of the screw or other article has entered the mold. These may cause the mold Damage to the lower mold, stripper plate or punch, guide column.

(7) Assembly error: The position and direction are incorrectly installed when the parts are mounted, resulting in damage to the mold.

(8) Spring factors: Insufficient spring force in the mold and breakage, and high stacking and high tilting of the stripper plate, abnormal spring preparation, these can also cause the machine to overlap and punch damaged parts.

(9) Improper stamping: The height adjustment of the work is too low, the oil loss of the guide post, the misfeed of the material bars, or the damage of the half-side material, peripheral equipment such as the feeder, receiver, and reclaimer, and the air pipe is not installed or returned. No opening, abnormal punch, etc., resulting in damage to the mold.

(10) Improper maintenance: The above points are caused when the screws are not locked or are not restored according to the original condition of the machine.
