Description

Technical Field

[0001] The utility model relates to the technical field of deep cavity molds, and in particular to a deep cavity mold capable of reducing defects in finished products. Background Art

[0002] Injection molding is a method of producing industrial products. Products usually use rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding and die casting. Injection molding machine (abbreviated as injection machine or injection molding machine) is the main molding equipment that uses plastic molding molds to make plastic products of various shapes of thermoplastics or thermosetting materials. Injection molding is achieved through injection molding machines and molds.

[0003] The traditional design uses a push plate plus an ejector pin and a secondary ejector mechanism. This results in a 100% failure rate of the ejector buckle being pulled out. To address this issue, we conducted technological innovation based on the existing deep-cavity mold and proposed a deep-cavity mold that can reduce defects in finished products.

[0012] Preferably, the ejector plate, B plate, sliding B plate and A plate are arranged parallel to each other.

[0013] Compared with the prior art, the beneficial effects of this invention are:

[0014] By setting up the core pulling and B plate, the core pulling is opened first, and then the B plate is ejected again, the mold opening is increased, and the rubber plug is not used. The limit pull rod is added to the ejector plate and the B plate. The mold opening order is A plate and B plate are opened first, and then the B plate and the ejector plate are simultaneously pulled 2mm apart to pull out the large middle insert, thereby reducing the friction and holding force of the product and ejecting it normally. The yield rate in injection molding production is increased by 30%, saving costs. Secondly, a robot is used to remove the product, making the device fully automated and reducing the manpower by one operator. BRIEF DESCRIPTION OF THE DRAWINGS
