Description

Technical Field

[0001] This utility model relates to the field of cutting mold technology, specifically a part peeling and cutting mold. Background Technology

[0002] Cutting molds are key equipment for achieving precise cutting and shaping of materials. They consist of two precisely combined upper and lower templates. During the cutting process, the raw material is clamped between the two templates. By applying specific pressure, the mold can accurately complete the cutting or shaping operation. This mechanism ensures that the processed products have consistency and high precision, meeting various production needs.

[0003] In existing technologies, cutting dies mostly adopt vertical stamping. After cutting, the waste material needs to be removed manually or by auxiliary equipment, which is inefficient and easily damages the parts. Although some integrated dies attempt to combine cutting and stripping functions, they have problems such as complex structure, high maintenance cost and poor reset reliability. For example, traditional dies rely on multiple sets of cylinders to work together, which has a high failure rate. Incomplete reset of the cutting block can cause parts to jam. Utility Model Content

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] A part peeling and cutting die, such as Figure 1 - Figure 4 As shown, the device includes a base 1, a lower mold 2 fixedly mounted on the upper surface of the base 1, a bracket 3 fixedly mounted on the outer wall of the base 1, several guide posts 6 fixedly mounted between the top of the bracket 3 and the upper surface of the base 1, a sliding plate 5 movably sleeved between the guide posts 6, an upper mold 7 fixedly connected to the bottom surface of the sliding plate 5, an installation groove 23 opened on the upper surface of the lower mold 2, several shearing mechanisms are arranged inside the installation groove 23, and the shearing mechanisms cooperate with each other, a support column 8 fixedly mounted on the bottom surface of the upper mold 7, and a cutting block 10 movably mounted inside the installation groove 23, a slider 16 fixedly connected to the bottom surface of the cutting block 10, and a blade 19 arranged on the outer wall of the cutting block 10 near the upper surface.

[0025] The shearing mechanism also includes a wedge block 12, which is fixedly installed on the inner wall of the mounting groove 23. The wedge block 12 moves the upper mold 7 downward, converting the vertical pressure into a horizontal thrust, thereby driving the shearing mechanism. A base plate 13 is fixedly connected to the bottom surface of the wedge block 12. An insert plate 15 is inserted inside the base plate 13. A connecting plate 14 is fixedly connected to one end of the insert plate 15. An insert rod 18 is fixedly connected to the upper surface of the connecting plate 14.

[0026] A connecting post 17 is fixedly inserted into the bottom surface of slider 16 near one end, and the upper end of the insert rod 18 is movably installed inside the connecting post 17. A return spring is provided between the upper end of the insert rod 18 and the top end inside the connecting post 17. When the cutting block 10 is pressed down and moved, it causes slider 16 to slide along the inclined surface of wedge block 12. At this time, the connecting plate 14 moves laterally under the action of slider 16, and the insert plate 15 moves along the inside of the base plate 13 with one end of the connecting plate 14. This can limit the movement position of slider 16, so that slider 16 can only move laterally, which can cooperate with the blade 19 to cut the excess part of the part smoothly. At the same time, when slider 16 slides and moves down along the inclined surface of wedge block 12, the connecting post 17 slides down along the outside of insert rod 18, and the return spring is squeezed and contracted. After the subsequent cutting is completed, the return force of the return spring can drive slider 16 to return to its original position, thereby ensuring that the cutting block 10 automatically returns to its original position and avoiding jamming.

[0027] Sleeve rods 22 are fixedly connected to the bottom surface of the slide plate 5 near both ends. Fixed posts 20 are fixedly connected to the upper surface of the base 1 near both sides. Buffer posts 11 are fitted on the upper ends of the two fixed posts 20, and the buffer posts 11 fit with the sleeve rods 22. Buffer springs are fitted on the outside of the fixed posts 20. The buffer posts 11 and buffer springs play the role of reducing the impact of mold closing and protecting the mold life.

[0028] The upper mold 7 has several limiting holes 21 through the outer wall. The lower mold 2 has several positioning pins 9 fixedly connected to the upper surface, and the positioning pins 9 fit with the limiting holes 21. The upper surface of the bracket 3 is fixedly installed with a cylinder 4, and the output end of the cylinder 4 is fixedly connected to the slide plate 5.

[0029] Specifically, during mold closing, cylinder 4 drives slide plate 5 to move down along each guide post 6, thereby driving upper mold 7 to move down, so that support post 8 is inserted into the part to support the part and prevent deformation during cutting. At the same time, sleeve rod 22 moves down with slide plate 5, sleeves outside buffer post 11 and moves down, so that buffer post 11, along the outside of sleeve rod 22, can buffer the downward pressure during mold closing, avoiding frequent impacts that reduce mold life. At the same time, when upper mold 7 moves down, it can be sleeved on each positioning post 9 through limiting hole 21, so that positioning post 9 and limiting hole 21 cooperate to eliminate mold closing misalignment error and improve cutting accuracy.

[0030] In use, the part is inserted into the slot formed between the various cutting blocks 10. Then, the cylinder 4 pushes the slide plate 5 down, the upper mold 7 contacts the part, the sleeve rod 22 presses down the buffer column 11, triggering the buffer spring to contract, the upper mold 7 continues to press down, pressing down on the part and the various cutting blocks 10. The various cutting blocks 10 move down, the slider 16 follows the cutting blocks 10 down and slides along the inclined surface of the wedge block 12, so that the slider 16 moves horizontally, so that the cutting blocks 10 move laterally. Similarly, the other cutting blocks 10 move at the same time, so that the various cutting blocks 10 press towards the part at the same time, and cooperate with the blade 19 to realize the operation of cutting and peeling off the excess part of the part, that is, the waste material.

[0031] After the cutting is completed, the cylinder 4 drives the slide plate 5 to move upward, which causes the sleeve rod 22 to disengage from the buffer column 11. The buffer spring returns to its original position, and the return spring in the connecting column 17 pushes the insert rod 18 to move upward to the initial position, which causes the cutting block 10 to return to its original position.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
