What is the retention board?
The retention plate is part of the internal molding molding mechanism to strengthen the mold and secure other inner parts, such as bushings and pins of ejection. The supporting plates are usually two -piece assemblies consisting of a support plate and a real roast plate. Supported parts, such as wizards and bumper pins, pass holes in the holder and are held in place against it with a backing plate. The plate is located in the rear of the mold between the mold core and the ejection mechanism. The board set is often equipped with internal channels for heating or fluid cooling. Injection forms
are relatively complex devices consisting of a laminar sandwich components that have joined to form a closed form. This collection of parts consists of two halves of the form of the product, which are secured between two heavy supporting plates. Half molds are in direct contact with the front support plate that is equipped with a stain or channelmugh that is roTinged material forced into a mold cavity. The area behind the half of the mold is occupied by several components, including holder boards, ejecting mechanism and rear support plate. The maintenance set of platelets, which is in contact with the back of the mold, is used to strengthen the mold and supports several pieces of other equipment necessary for the pressing process.
The grip assembly consists of two flat plates, which are placed back behind half of the mold. The plate in contact with the rear fungus is known as a storage board and the other as a ejector. These two boards support other parts of molds such as guide pins, ejection pins and their related cases. The wizards and ejecting pins usually pass through the bushings on the retention plate and are held on the spot by the ejector. It is located behind the retained ASSEMBLY board is a ejector box and finally the rear support plate.
after completionThe formation is removed by the front support plate along with half the front mold. The ejection mechanism then forces careful plates and ejecting pins forward to push part of the mold. Maintenance plates are also often used as rear cooling or heating elements in the form of a specific application. This function is achieved by incorporating channels or cores into the board assembly through which steam or chilled water circulates.
