What is the standard injection mold development process?
Original: Original | Author: DGMF Mold Clamps | Publish Time: 2020-04-21 | 14875 Views | Share:
Before drawing the final assembly drawing of the mold, the process drawing should be drawn up, and it should meet the requirements of the workpiece drawing and process data. The size guaranteed by the next process shall be marked with the words "process size" on the drawing. If, after molding, no other machining is performed except for repairing burrs, the process drawing is exactly the same as the workpiece drawing.

Molding equipment

The injection volume, injection pressure, and clamping force are not enough. Are there any problems with the installation of the mold, the south core of the plastic parts, and the demolding? Is the nozzle of the injection machine properly contacting the nozzle sleeve?

Mold structure

Whether the location of the parting surface and the precision of the finishing meet the needs, will there be flashing, and whether the plastic parts can be left on the side of the mold with the ejector after the mold is opened.

Whether the demoulding method is correct, whether the size, position, and quantity of the extension rod and push tube are appropriate, will the push plate be stuck by the core, and will it cause scratches to the molded parts.

Mold temperature adjustment. The power and number of heaters; whether the position, size, and a number of cooling medium flow lines are appropriate.

The method for dealing with undercuts made of plastic parts is whether the mechanism for removing the undercuts is appropriate, for example, whether the slider and the push rod in the inclined guide column core pulling mechanism interfere with each other.
