Technical Field

[0001] This utility model relates to the field of mold processing technology, specifically to a positioning fixture for mold processing. Background Technology

[0002] Mold processing refers to the processing of forming and blanking tools, and also includes shearing dies and die-cutting dies. During the grinding and processing of molds, positioning fixtures are used to fix the mold blank. For example, patent application number 201921048025.3, patent title: "A Positioning Fixture for Mold Processing," includes a base plate. A sliding groove is formed diagonally on the upper surface of the base plate. A first clamping block is slidably installed at one end of the sliding groove on the upper part of the base plate, and a second clamping block is slidably installed at the other end of the sliding groove on the upper part of the base plate. The bottom of the base plate... The device is equipped with a bidirectional screw, one end of which is movably fitted with a handle. A locking ring is fixedly installed at the front corner of the base plate via a first fixing rod and a second fixing rod. A bolt connects the handle and the locking ring, and a fixing cap is fixedly installed at one end of the bolt. A hand-tightening nut is fitted over the bolt. This utility model provides a positioning fixture for mold processing, which can conveniently position the mold and keep it in the center of the base plate. It also serves to fix the mold and prevent it from shaking during processing.

[0003] The aforementioned technologies have the following drawbacks: the positioning fixture uses a rotating bidirectional screw to bring the first and second clamping blocks closer together, thereby clamping and fixing the mold blank. However, due to worker error, the positioning fixture may apply excessive force when clamping the mold blank, causing deformation of the mold blank and thus affecting the practicality of the positioning fixture.

[0004] Therefore, it is necessary to redesign and modify the positioning tooling to effectively prevent its low practicality. Utility Model Content

[0006] To achieve the above objectives, the present invention provides the following technical solution: a positioning fixture for mold processing, comprising a housing, a support plate fixedly connected inside the housing, an electromagnet fixedly connected to the top of the support plate, a magnetic plate movably connected to the top of the electromagnet, and the top of the magnetic plate extending to the outside of the housing;

[0007] The cooling mechanism includes a fan fixedly connected to the front of the housing and located at the bottom of the support plate. The back of the fan extends to the outside of the housing. A thermoelectric cooler is fixedly connected inside the housing and located at the bottom of the support plate. Heat-conducting plates are fixedly connected to the top and bottom of the thermoelectric cooler. An exhaust port is provided on the back of the housing at the bottom of the thermoelectric cooler. A ventilation opening is provided on the surface of the support plate at the back of the electromagnet. An exhaust hole is provided on the front of the housing at the top of the support plate.

[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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1 to 6 As shown, the positioning fixture for mold processing provided by this utility model includes a shell 1, a support plate 2 fixedly connected inside the shell 1, an electromagnet 3 fixedly connected to the top of the support plate 2, a magnetic conductive plate 4 movably connected to the top of the electromagnet 3, and the top of the magnetic conductive plate 4 extending to the outside of the shell 1.

[0025] The cooling mechanism includes a fan 5 fixedly connected to the front of the outer casing 1 and located at the bottom of the support plate 2. The back of the fan 5 extends to the outside of the outer casing 1. A thermoelectric cooler 6 is fixedly connected to the inside of the outer casing 1 and located at the bottom of the support plate 2. Heat-conducting plates 7 are fixedly connected to the top and bottom of the thermoelectric cooler 6. An exhaust port 8 is opened on the back of the outer casing 1 at the bottom of the thermoelectric cooler 6. A ventilation port 9 is opened on the surface of the support plate 2 at the back of the electromagnet 3. An exhaust hole 10 is opened on the front of the outer casing 1 at the top of the support plate 2. A dustproof mechanism is provided on the front of the outer casing 1. A wear-resistant mechanism is provided on the top of the outer casing 1.

[0026] refer to Figure 2 The dustproof mechanism includes a fixed frame 11 fixedly connected to the front of the housing 1 and located outside the fan 5 and the exhaust port 10 respectively. Dustproof nets 12 are fixedly connected inside the fixed frame 11 and inside the exhaust port 8.

[0027] As a technical optimization of this utility model, by setting a fixing frame 11 and a dustproof net 12, dust and other impurities are prevented from entering the interior of the outer shell 1 and adhering to the heat-conducting plate 7, which would affect the heat conduction efficiency of the heat-conducting plate 7 and reduce the cooling effect of the cooling mechanism.

[0028] refer to Figure 6 The wear-resistant mechanism includes a slot 13 located on the top of the housing 1 and outside the magnetic plate 4. The top of the magnetic plate 4 is movably connected to a wear-resistant plate 14. The bottom of the wear-resistant plate 14 is fixedly connected to a block 15. The bottom of the block 15 extends into the interior of the slot 13. The top of the wear-resistant plate 14 is provided with an anti-slip mechanism.

[0029] As a technical optimization of this utility model, by setting a wear-resistant plate 14, friction between the magnetic guide plate 4 and the mold blank is avoided, which would cause the magnetic guide plate 4 to be worn. The slot 13 and the block 15 facilitate the disassembly and assembly of the wear-resistant plate 14 and the outer shell 1, making it convenient for workers to replace the worn wear-resistant plate 14.

[0030] refer to Figure 6 The anti-slip mechanism includes a mounting groove 16 formed on the top of the wear-resistant plate 14, and an anti-slip rubber 17 is fixedly connected inside the mounting groove 16. The top of the anti-slip rubber 17 extends to the outside of the mounting groove 16.

[0031] As a technical optimization of this utility model, by setting the mounting groove 16 and the anti-slip rubber 17, the surface friction of the wear-resistant plate 14 is increased, so as to avoid the mold blank from slipping off the positioning fixture due to the low surface friction of the wear-resistant plate 14 when the electromagnet 3 is not started.

[0032] refer to Figure 3The top of the support plate 2 and the bottom of the magnetic plate 4 are both fixedly connected to the reinforcing ribs 18 located outside the electromagnet 3, and both sides of the reinforcing ribs 18 are fixedly connected to the inner wall of the outer shell 1.

[0033] As a technical optimization of this utility model, by setting reinforcing ribs 18, the support plate 2 and the magnetic plate 4 are supported and reinforced, so as to prevent the support plate 2 and the magnetic plate 4 from bending and deforming when they are squeezed.

[0034] refer to Figure 4 The back of the outer shell 1 is fixedly connected to a breathable mesh cover 19 located on top of the support plate 2. The inside of the breathable mesh cover 19 is movably connected to a solid insect repellent 20 through a non-woven fabric.

[0035] As a technical optimization of this utility model, by setting up a breathable mesh cover 19 and a solid insect repellent 20, the gas generated when the solid insect repellent 20 evaporates is used to drive away insects and ants, thereby preventing insects and ants from breeding in the positioning fixture.

[0036] The working principle and usage process of this utility model are as follows: When in use, the mold blank is placed on the wear-resistant plate 14, and then the electromagnet 3 is activated. The magnetic field generated by the electromagnet 3 is enhanced by the magnetic plate 4, thereby adsorbing and fixing the mold blank. At the same time, the fan 5 is activated, and the fan 5 delivers airflow into the outer shell 1. The airflow is divided into upper and lower airflows. When the two airflows pass through the heat-conducting plate 7, the semiconductor cooling plate 6 transfers the heat of the upper airflow to the lower airflow through the heat-conducting plate 7, making the upper airflow cold air and the lower airflow hot air. The lower airflow is discharged from the outer shell 1 through the exhaust port 8, and the upper airflow enters the support plate 2 through the ventilation port 9, using the cold air to cool the electromagnet 3 and prevent the electromagnet 3 from overheating.

[0037] In summary: This positioning fixture for mold processing uses an electromagnet 3 and a magnetic plate 4 to magnetically attract the mold blank. Since the electromagnet 3 has a magnetic force of no less than 14 kg per square centimeter, it prevents the mold blank from shifting when the worker grinds it. Because the mold blank is fixed by magnetic force, the positioning fixture is prevented from damaging the mold blank. Furthermore, a cooling mechanism is used to cool the electromagnet 3, preventing it from being damaged due to overheating.
