Description

Strengthen cutting muscle upper slitter and tendon-cutting device

Technical field

The utility model relates to a kind of reinforcement and cuts muscle upper slitter and tendon-cutting device, is used for the useless framework excision of plastic packaging product (like TO-220), belongs to and cuts the muscle technical field of mold.

Background technology

In cutting the muscle process, cut the muscle upper slitter and fix by the upper slitter holder, accomplish product through stripper and discharging mold insert incision framework and cut muscle.As depicted in figs. 1 and 2; Be traditional tendon-cutting device assembly drawing and exploded view, described traditional tendon-cutting device by unloading block 1, cut muscle upper slitter 2, upper slitter holder 3, discharging mold insert 4, stripper 5, die socket 6, down cutter press strip 7, cut cutter 8 under the muscle, bearing material piece 9, product 10 and pilot pin 11 and form.Like Fig. 3 and shown in Figure 4, be respectively traditional muscle upper slitter front view and side view cut, traditional integral thickness of cutting the muscle upper slitter is consistent, and the edge of a knife is smooth.All need cut the muscle cross cutting after the product encapsulation and remove frame waste.Because spacing is less and need the link waste material between the excision pin between the framework pin, so it is very weak to cut the processing of muscle upper slitter, mould can influence the intensity and the service life of upper slitter when using.Contact-making surface between the upper slitter edge of a knife and the framework is big in addition, and cut muscle product pin place and may produce impression, thus the quality that the muscle product is cut in influence.At this moment just need a kind of reinforcement to cut the muscle upper slitter, cut muscle upper slitter intensity and service life to reach enhancing, improve the purpose that product is cut the muscle quality.

Summary of the invention

The purpose of the utility model provides the reinforcement in a kind of service life that has higher intensity and grow and cuts muscle upper slitter and tendon-cutting device.

In order to achieve the above object; The utility model provides a kind of reinforcement to cut the muscle upper slitter, comprises cutting muscle upper slitter body, it is characterized in that; The described muscle upper slitter upper part of body of cutting is a standing part; The bottom is a cutting part, and the thickness a of described standing part is than the big 1～3mm of thickness b of cutting part, and the edge of a knife of described cutting part is skewed.

The utility model also provides a kind of tendon-cutting device, it is characterized in that, comprises die socket and stripper; Die socket is provided with the bearing material piece and cuts cutter under the muscle; The bearing material piece is provided with pilot pin, cuts under the muscle cutter and fixes through cutter press strip down, and the plastic packaging product is located on the bearing material piece and through the pilot pin location; The stripper downside connects unloading block and discharging mold insert successively; The discharging mold insert is positioned on the plastic packaging product, and the middle part of stripper, unloading block and discharging mold insert is provided with above-mentioned reinforcement and cuts the muscle upper slitter, and the upper end that the muscle upper slitter is cut in reinforcement is fixed on the upper slitter holder.

Compared with prior art, the beneficial effect of the utility model is: the utility model is cut the muscle upper slitter, to reduce edge of a knife contact-making surface through strengthening, and has increased the intensity of upper slitter, has improved upper slitter service life, has improved product and has cut the muscle quality.

The specific embodiment

Specify the utility model below in conjunction with embodiment.

Embodiment

Like Fig. 7 and shown in Figure 8; For strengthening cutting muscle upper slitter front view and side view; Described reinforcement is cut the muscle upper slitter and is comprised and cut muscle upper slitter body, and the described muscle upper slitter upper part of body of cutting is a standing part 12, and the bottom is a cutting part 13; The thickness a of described standing part 12 is than the big 2mm of thickness b of cutting part 13, and the edge of a knife of described cutting part 13 is skewed.

Like Fig. 5 and shown in Figure 6, be the tendon-cutting device assembly drawing and the exploded view of the utility model, described tendon-cutting device; Comprise die socket 6 and stripper 5, die socket 6 is provided with bearing material piece 9 and cuts cutter 8 under the muscle, and bearing material piece 9 is provided with pilot pin 11; Cut under the muscle cutter 8 through cutter press strip 7 is fixing down; Plastic packaging product 10 is located on the bearing material piece 9 and through pilot pin 11 location, stripper 5 downsides connect unloading block 1 and discharging mold insert 4 successively, and discharging mold insert 4 is positioned on the plastic packaging product 10; The middle part of stripper 5, unloading block 1 and discharging mold insert 4 is provided with above-mentioned reinforcement and cuts muscle upper slitter 14, and the upper end that muscle upper slitter 14 is cut in reinforcement is fixed on the upper slitter holder 3.The widthwise edges of muscle upper slitter 14 is cut in reinforcement and the gap of discharging mold insert 4 is 0.015mm, prevents to strengthen cutting 14 its swings of muscle upper slitter, cuts muscle upper slitter penetraction depth by limited post and limiting plate are confirmed up and down.

During use, plastic packaging product 10 is positioned on the bearing material piece 9 through pilot pin 11, driving upper slitter holder 3 drives strengthening cutting muscle upper slitter 14 passes unloading block 1 and moves downward with discharging mold insert 4; Muscle is cut in realization, because the frequent folding of mould, if the upper slitter integral thickness is for cutting muscle knife-edge part thickness; Then the intensity of upper slitter and wearability are very poor, and upper slitter is easy to distortion even breaks down, and only thicken at the upper slitter standing part; Can not influence and cut the muscle size; And can strengthen upper slitter intensity greatly, improve the anti-wear performance of cutting the muscle upper slitter, reduce to cut the distortion of muscle upper slitter.It then is in order to reduce the contact-making surface of upper slitter and shell frame products that the upper slitter knife-edge part is done gradient, and the upper slitter contact-making surface is little, and it is then little to cut the muscle resistance, does not have impression so cut muscle product pin place, cuts the muscle quality thereby improve product.After cutting the muscle completion, strengthen cutting the muscle upper slitter and return the discharging mold insert, discharging is unobstructed.
