Description

Technical Field

[0001] The utility model relates to the technical field of injection mold processing, in particular to a wire cutting device for injection mold processing. Background Technique

[0002] An injection mold is a tool for producing plastic products; it is also a tool for endowing plastic products with a complete structure and precise dimensions; conventional injection molds are mostly produced by wire cutting devices.

[0003] The wire cutting device mainly consists of three parts: a machine tool, a numerical control system, and a high-frequency power supply. The numerical control system is composed of a single-chip microcomputer, a keyboard, and a frequency conversion detection system, and has main functions such as gap compensation, linear interpolation, circular interpolation, and automatic wire breakage processing.

[0004] When the wire cutting device cuts the mold raw material during use, in order to ensure the stability of the mold raw material, a fixture is needed to fix the mold raw material. Since the fixture itself also needs to be fixedly arranged, and the fixture also needs to drive the mold raw material to move in the horizontal plane, so that the wire cutting device can cut out a suitable shape on the mold raw material. However, such a setting results in too many devices such as fixing components and driving modules around the fixture, and the waste chips generated during the cutting process are easily deposited on them, thereby affecting the normal operation of the driving module.

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0026] Refer to Figures 1 - 5, A wire cutting device for injection mold processing, including a base 1. A support table 2 is installed on the top of the base 1. A blanking groove 3 is opened on the top of the support table 2, and strip-shaped grooves 4 are opened on both sides of the blanking groove 3. A first guiding shaft 5 is arranged in the strip-shaped groove 4. The end of the first guiding shaft 5 is fixed to the end of the strip-shaped groove 4, and first sliders 6 are slidably installed at both ends of the first guiding shaft 5. Cross beams 7 are arranged at both ends in the blanking groove 3. The ends of the cross beams 7 correspond to the two strip-shaped grooves 4 respectively and are connected to the first sliders 6, enabling the cross beams 7 to perform horizontal linear motion in the blanking groove 3;

[0027] Further, as Figure 1 shown, a first connecting plate 8 with a top bent in an "L" shape is installed on the top of one end of the cross beam 7. A first hand-tightening bolt 9 is threadedly installed on the top of the first connecting plate 8. The bottom of the first hand-tightening bolt 9 corresponds to the top of the support table 2. After adjusting the cross beam 7 to a suitable position, the first hand-tightening bolt 9 can be turned to press the end of the first hand-tightening bolt 9 against the support table 2, thereby fixing the moved cross beam 7.

[0028] As Figure 1 shown, a slide rail 10 is arranged in parallel above the cross beam 7. Both ends of the slide rail 10 are connected to a connecting frame 11 and fixed to the cross beam 7. Second sliders 12 are slidably installed at both ends of the slide rail 10, enabling the second sliders 12 to perform linear motion perpendicular to the movable direction of the cross beam 7 on the blanking groove 3;

[0029] A clamp for clamping the corner of the mold to be cut is installed on the top of the second slider 12. Among them, as Figure 1 and Figure 5 shown, the clamp includes a first clamping plate 13. The first clamping plate 13 is fixed on the second slider 12. A support plate 15 is arranged in parallel above the first clamping plate 13. The side of the support plate 15 is fixed to the first clamping plate 13 through a limiting plate 14. A second clamping plate 16 is arranged in parallel below the support plate 15. The top of the second clamping plate 16 is connected to a second hand-tightening bolt 17. The second hand-tightening bolt 17 penetrates through the support plate 15 and is threadedly connected to it. During use, the corner of the mold to be cut can be placed on the first clamping plate 13, and the second hand-tightening bolt 17 can be turned to press the second clamping plate 16 against the top of the mold to be cut, thereby clamping and fixing the mold to be cut. During actual use, the part of the mold to be cut except for the corner position can be unobstructed, so that the waste generated during the cutting process can directly fall into the blanking groove 3, facilitating the collection of waste.

[0030] Further, a second connecting plate 18 is installed on the outer top of the limit plate 14, and a third hand-tightening bolt 19 is threadedly connected to the second connecting plate 18. The end of the third hand-tightening bolt 19 corresponds to the slide rail 10. After the fixture moves to the fixed position, the fixture can be fixed to ensure the stability of the fixture. During the actual use process, the limit plate 14 is "L"-shaped, and the inner sides of the four limit plates 14 are arranged oppositely. After placing the mold to be cut on the first clamping plate 13, the cross beam 7 and the fixture can be moved again, so that the corner of the mold to be cut abuts against the inner side of the limit plate 14, and cooperate with the hand-tightening bolt on the connecting plate, so as to ensure the stable state of the mold to be cut during cutting.

[0031] It should be noted that the positions of the cross beam 7 and the fixture are adjustable, so that the fixture can be adjusted according to the specifications of the mold to be cut, thereby improving the adaptability of the fixture to the mold to be cut.

[0032] As Figure 1 and Figure 2 shown, a wire cutting machine 20 is provided above the blanking chute 3, and the front projection position of the fixture is located in the middle of the wire cutting machine 20. A first linear motor 21 is arranged at the bottom of one end of the wire cutting machine 20 away from the blanking chute 3. The first linear motor 21 is fixed on the support frame 22, and the bottom of the support frame 22 is fixed on the fixed frame 24. A second linear motor 23 is arranged on the fixed frame 24, and the second linear motor 23 is fixed on the side of the base 1. Driven by the linear motor, the wire cutting machine 20 can move freely in the horizontal plane above the blanking chute 3, so as to perform a cutting operation with a controllable cutting trajectory on the mold to be cut. And the linear motor, as the moving drive of the wire cutting machine 20, is also arranged away from the blanking chute 3, so as to reduce the probability of waste and other sundries falling on it and ensure the normal use of the linear motor.

[0033] Specifically, the bottom of the blanking chute 3 is inclined, and a waste discharge port 27 penetrating through the base 1 is opened at the bottom of the blanking chute 3. After waste and other sundries fall into the blanking chute 3, the waste and other sundries will be discharged from the waste discharge port 27 along the bottom slope of the blanking chute 3, so as to centrally process the waste and other sundries.

[0034] When the second linear motor 23 drives the wire cutting machine 20 to move, as Figure 2 shown, a second guide shaft 26 is arranged in parallel below the second linear motor 23. The end of the second guide shaft 26 is fixed to the base 1 through a fixed seat, and a reinforcing rod 25 is slidably installed on the second guide shaft 26. The other end of the reinforcing rod 25 is fixed to the fixed frame 24, which supports the setting of the wire cutting machine 20 on the second linear motor 23, so as to share the pressure of the wire cutting machine 20 on it for the second linear motor 23 and play a protective role for the second linear motor 23.

[0035] It should be noted that on the side of the support table 2 away from the second linear motor 23, there is a baffle 28 with an end bent in an "L" shape. The end of the baffle 28 corresponds to the end face of the support table 2. Inside the baffle 28, there is a lead screw 29. The top of the lead screw 29 is rotatably installed on the bottom of the support table 2, and a driving motor 31 is connected to the bottom of the lead screw 29. The driving motor 31 is fixed to the base 1 through a bracket. A moving seat 30 is threadedly connected to the lead screw 29 through a nut. The moving seat 30 is fixed to the baffle 28. After fixing the mold to be cut with a fixture, the driving motor 31 can be started to raise the baffle 28, so as to block the periphery of the support table 2, thereby blocking the flying waste chips during the cutting process to prevent waste chips and other sundries from splashing everywhere and polluting the surrounding environment. In actual use, the baffle 28 is one of a transparent plastic plate, a transparent acrylic plate, and a transparent glass plate. The transparent baffle 28 does not affect the operator's observation of the cutting process through the baffle 28.

[0036] Furthermore, on the side of the base 1, there is a third guide shaft 32 parallel to the lead screw 29. The top of the third guide shaft 32 is fixed to the bottom of the support table 2, and the bottom of the third guide shaft 32 is fixed to the connecting seat 33. The connecting seat 33 is fixed to the base 1. A sliding sleeve 34 is slidably installed on the third guide shaft 32. The sliding sleeve 34 is fixed to the baffle 28, which plays a guiding role in the lifting of the baffle 28, thereby improving the stability of the lifting of the baffle 28.

[0037] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent replacements or changes, and should be covered by the protection scope of the present invention.
