Cutting die and tool structure of die-cut cardboard

This creation relates to a die, and in particular to a die for punching honeycomb paper and a tool structure disposed on such a die.

After the product is manufactured, it usually needs to be packaged. Many electronic products need to be shock-absorbing during packaging to avoid damage caused by external force squeeze or collision during handling and transportation.

At present, the most commonly used product packaging shock absorbing material is EPS (also known as styrofoam, Chinese full name is expandable polystyrene), of course, EPS is difficult to decompose under natural conditions, which is easy to cause environmental pollution; to avoid environmental pollution Then, cardboard is used as a packaging shock absorbing material, such as a conventional corrugated cardboard or honeycomb paperboard.

Honeycomb paperboard is made of a special paper through a special processing program. The honeycomb core has a continuous hexagonal honeycomb structure, which makes the honeycomb paperboard have the characteristics of light weight, high strength and high rigidity. It is a kind of cushioning and heat preservation. , heat insulation, soundproof packaging materials. At the thickness of the same raw paper, honeycomb paperboard has higher pressure resistance than ordinary corrugated paperboard, and its cost is relatively low compared with flat paper of the same thickness.

However, it is necessary to process on the honeycomb paperboard to match the shape of the product to produce packaging materials of different heights, which generally need to be formed by multiple processing or bonding. However, the method of multiple processing is not only time-consuming and labor-intensive, but the result of bonding will reduce the strength of the structure. Moreover, if the tool cuts the honeycomb paperboard multiple times in the same part, the upper and lower repeated actions will destroy the cardboard. The honeycomb structure of the core, and the easy to jam the tool makes it difficult to continue the next action.

In order to be able to form the packaging material of the honeycomb paper into a product at one time, the die of the present invention comprises an upper mold part, a press mold part and a bottom mold part arranged in the longitudinal direction, and the mold part is placed on the upper mold part. And the bottom mold portion is elastically coupled integrally with the upper mold portion, so that the upper mold portion can be longitudinally elastically displaced relative to the mold portion, and the bottom mold portion is used for supporting the honeycomb paperboard to be processed; The upper mold portion further includes a plurality of crushing bodies and cutters protruding toward the pressing mold portion, the plurality of crushing bodies having different heights for matching the shape to be formed by the honeycomb paperboard, and the plurality of cutters are distributed at the plurality of pressures Adjacent sides of the body, and the height of the tool must be greater than the adjacent crush body. During operation, the upper mold body is pressed to move the cutter and the crushing body toward the honeycomb paperboard at the same time. Since the height of the cutter is larger than the crushed body, the cutter will first pierce the surface of the honeycomb paperboard, and the cutter has been punched and destroyed to destroy the honeycomb. The surface of the paperboard makes it easier for the crushed body to crush the honeycomb-like structure of the paper core after contacting the honeycomb paperboard, and because the height of the crushed body is different, the paper is crushed on the honeycomb paperboard. After the core is formed with different depths of concave steps, in order to fit and accommodate different shapes of products, and can be molded into a shock absorbing packaging material of the product at one time.

Preferably, the tool of the present invention has a flat blade portion, and the blade portion is continuously connected in series by a plurality of oblique blades and a blade back at a side away from the upper mold portion, each of the saw teeth The peak end is advanced by a position of about 10 degrees from the end of the valley, and the angle between the oblique edge and the back of the blade is about 45 degrees; thereby making it easier for the cutter to pierce the honeycomb board during punching, and When the tool is deeper into the longitudinal direction of the paper core, the design of each of the peak ends of the saw tooth leads the end of the valley end by about 10 degrees, so that the angle between the inclined blade edge of the sawtooth valley end and the back of the blade does not get stuck to the paper core. The honeycomb structure can be smoothly cut without causing tears and tears to form ugly burrs, resulting in a better stamping appearance.

Referring to FIG. 1 to FIG. 3 at the same time, the die structure of the present invention comprises an upper die part 1, a die part 2, and a bottom die part 3 arranged longitudinally, and the die part 2 is placed on the upper die. Between the portion 1 and the bottom mold portion 3, the upper mold portion 1 is elastically coupled integrally with the upper mold portion 1, so that the upper mold portion 1 can be elastically displaced longitudinally relative to the mold portion 2, and the bottom mold portion 3 is used for support. Processed honeycomb paperboard 4.

A plurality of springs 10 are coupled between the upper mold portion 1 and the die portion 2 to enable the upper mold portion 1 to move elastically relative to the mold portion 2. Preferably, each spring 10 is provided with a middle portion. The shaft 11 and one end 110 of the support shaft 11 are fixed to the die portion 2, and the end thereof extends into the upper mold portion 1 and passes through the support shaft 11, thereby providing the upper mold portion 1 to be more stable and less biased for longitudinal elasticity. motion.

The upper mold portion 1 is provided with a plurality of crushing bodies 12 and a cutter 5 which protrude toward the die portion 2, and as shown in FIG. 5, the plurality of crushed bodies 12 have different heights in accordance with the shape to be formed by the honeycomb paperboard 4. The plurality of cutters 5 are distributed on adjacent sides of the plurality of crushers 12, and the height of the cutters 5 must be greater than the adjacent crushers 12.

The die portion 2 is provided with corresponding holes 20 for allowing the crushing body 12 and the cutter 5 to pass through at the corresponding plurality of crushing bodies 12 and the cutter 5, so that the upper mold portion 1 is elastically moved relative to the stamper portion 2 The plurality of crushing bodies 12 and the cutter 5 can be processed through the die portion 2 to process the honeycomb paperboard 4, and the bottom mold portion 3 is also provided with a receiving groove 30 at the vertical corresponding cutter 5, thereby allowing the cutter 5 to be The tank 30 is active.
