Structural Design Of Drawer Mould

  • The drawer is very common in our daily life, so Drawer Mould is becoming more and more popular. The following is about the structural design of the drawer mold:

    1. Pouring system (hot runner system):

    Mold-Master needle valve hot nozzle is used to enter the water at two points; the entry position has been verified by MoldFlow analysis

    1. Forming structure:
    2. Parting surface design: pull out from the R corner of the product, the smooth transition at the corner, no stepped sharp corners.

    2 Treatment of thin steel at the insertion position: inserts in the two insertion positions of the front mold for easy maintenance and

    1. Lateral parting and core pulling mechanism:
    2. Combined inclined roof structure:

    The inclined roof is designed into three sections, the large inclined roof in the middle is ejected obliquely under the ejection drive, and the small inclined roof on both sides and the large inclined roof have an angle difference in the ejection direction (the angle of the small inclined roof is smaller than the large inclined roof); The large inclined roof utilizes the horizontal structural angle between the large and small inclined roofs, and the small inclined roofs on both sides are dragged by the "T"-shaped strip to be ejected in an oblique direction while shrinking and demolding inward.

    1. Row position inclined roof structure:

    The large row position moves outwards, and the row position slope is blocked by the stopper fixed on the B board so that it moves upward under the action of the row position chute to escape the undercut; the stop block is separated from the row position slope, and the row position The inclined top moves outward together with the large row position to complete demolding.

    1. The structure of the bullet front mold: (front mold row position)

    The inside of the drawer front is inverted, and the front mold adopts the structure of the front mold; the front mold has a length of 670mm, so there are oblique guideposts on both sides for guidance. There are four sets of springs in the middle of the row for the ejection of the front mold; in addition, two rows There are three sets of Sanda screws at the end and the middle.

    1. Ejection and reset system:

    Pushing and slanting ejection, ejection is safe and convenient to take parts; because the oil pump position has strict sequence requirements when opening and closing the mold, so the oil pump position is equipped with a card to control the sequence of actions.

    1. Cooling system:

    Like the Bucket Mould, the original front mold makes the mold cool quickly, and each row of the inclined roof and the hot nozzle has separate water transportation, and the overall cooling is sufficient.
