Detailed Description

The utility model will now be described in detail with reference to the drawings and specific examples. The present embodiment is implemented on the premise of the technical scheme of the present utility model, and a detailed implementation manner and a specific operation process are given, but the protection scope of the present utility model is not limited to the following examples.

It should be noted that: like reference numerals and letters denote like items in the following figures, and thus once an item is defined in one figure, no further definition or explanation thereof is necessary in the following figures.

Some embodiments of the present utility model are described in detail below with reference to the accompanying drawings. The embodiments described below and features of the embodiments may be combined with each other without conflict.

The utility model provides a die-cut discharging device of pad mould side gives sound insulation, as shown in fig. 1 through 4, including upper die base 1, lower mold core 8 and punch cutter piece 7, hydro-cylinder 3, punch cutter piece 7 and be circle sword or square sword, be equipped with hydro-cylinder fixing base 2 on the hydro-cylinder 3, and the output shaft of hydro-cylinder 3 punch cutter piece 7, punch cutter piece 7 is equipped with the round hole, is equipped with ejector pin 5 in the hydro-cylinder fixing base 2, and the position of ejector pin 5 corresponds with the round hole position in the punch cutter piece 7. The axis of the ejector rod 5 and the axis of the round hole are on the same straight line.

Through setting up the round hole to and with this round hole complex ejector pin, the ejector pin is fixed to when the hydro-cylinder withdraws, can drive and dash the cutter piece, thereby dash the round hole on the cutter piece and be close to the ejector pin motion, the ejector pin can insert in the round hole, finally will dash the waste material on the cutter piece and clear away.

In general, the outer diameter of the ejector rod 5 is smaller than or equal to the inner diameter of the round hole, and the difference of 1-3 mm is preferably reserved if the outer diameter is smaller than or slightly smaller than the inner diameter of the round hole under normal conditions.

Normally, more than one ejector rod and round hole can be arranged, the number of the ejector rods 5 is consistent with the number of the round holes in the punching cutter block 7, and specific data are required according to practical situations, such as the projection area of the cutting surface of the punching cutter block 7.

In addition, the device also comprises a push rod fixing plate 4, and the push rod 5 is fixed on the oil cylinder fixing seat 2 through the push rod fixing plate 4, so that the device is convenient to install.
