Description

Technical Field

[0001] The utility model relates to the technical field of plastic molds, in particular to a plastic mold for producing precision parts. Background Art

[0002] Plastic products require molds throughout their production and processing. A plastic mold is a shorthand term for a modular mold used for compression molding, extrusion molding, injection molding, blow molding, and low-foaming molding. By coordinating the mold's male and female dies and auxiliary molding systems, a wide range of plastic parts can be produced in various shapes and sizes.

[0003] Existing plastic molds are prone to damage when used for a long time. Since the existing mold bucket is not easy to disassemble and replace, it will bring great inconvenience to people. For this reason, we propose a plastic mold for the production of precision parts to solve the above problem. Utility Model Content

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Reference Figure 1-4 A plastic mold for the production of precision parts includes a base plate 1, two symmetrically arranged connecting plates 2 are fixedly installed on the top of the base plate 1, and a fixing groove 3 is opened on the side of the two connecting plates 2 close to each other. The same fixing rod 4 is fixedly installed on the top inner wall and the bottom inner part of the fixing groove 3, and the two fixing rods 4 are slidably installed with the same lifting plate 6. The bottom of the lifting plate 6 is fixedly installed with a first spring 5, and the top of the two connecting plates 2 is fixedly installed with a top plate 8. The top of the top plate 8 is fixedly installed with a push rod motor 7. The output shaft of the push rod motor 7 is fixedly installed on the top of the lifting plate 6. The bottom of the lifting plate 6 is fixedly installed with a connecting seat 9, and the bottom of the connecting seat 9 is provided with a spring groove 10. One end of a plurality of second springs 11 is fixedly mounted on the top inner wall of the spring groove 10, and a pressure plate is fixedly mounted on the other end of the second spring 11. A mounting seat 12 is provided at the bottom of the pressure plate, and a mold 14 is fixedly mounted on the bottom of the mounting seat 12. Circular grooves are provided on the inner walls on both sides of the spring groove 10, and a groove 19 is provided on the top inner wall of the circular groove. The same fixing column 20 is fixedly mounted on the inner walls on both sides of the groove 19, and a square plate is slidably mounted on the fixing column 20. A fourth spring 21 is fixedly mounted on one side of the square plate. The bottom of the square plate extends into the circular groove and is fixedly mounted with a wedge block 18. A slide plate 17 is fixedly mounted on one side of the wedge block 18, and one side of the slide plate 17 extends to the outside of the circular groove.

[0022] In the present invention, the number of the second springs 11 is eight to sixteen, and the eight to sixteen second springs 11 are arranged at equal intervals. The arrangement of multiple second springs 11 enables the mold 14 to be installed more securely.

[0023] In the present invention, a card slot 22 is provided on both sides of the mounting seat 12, and one side of the wedge block 18 extends into the card slot 22 and is clamped with the card slot 22. Through the clamping arrangement of the wedge block 18 and the card slot 22, the mounting seat 12 can be well limited when the wedge block 18 is clamped into the card slot 22.

[0024] In the present utility model, fixing holes are provided on both sides of the connecting seat 9, and a pull plate 25 is slidably installed in the fixing hole. A limiting groove is provided on the top inner wall of the fixing hole, and a limiting seat 24 is slidably installed in the limiting groove. A fifth spring 23 is fixedly installed on one side of the limiting seat 24. Through the setting of the fifth spring 23, the pull plate 25 can be well buffered.

[0025] In the present utility model, a first clamping ring 13 is fixedly installed on one side of the pull plate 25, one end of a plurality of third springs 15 is fixedly installed on one side of the first clamping ring 13, and a second clamping ring 16 is fixedly installed on the other end of the third spring 15. The second clamping ring 16 cooperates with the mounting seat 12, and the mounting seat 12 can be further clamped and limited by the cooperation setting of the second clamping ring 16 and the mounting seat 12.

[0026] In the present invention, the number of the third springs 15 is five to ten, and the five to ten third springs 15 are evenly spaced around the circumference. The installation seat 12 can be further clamped by the arrangement of multiple third springs 15 .

[0027] In the present invention, when the mold 14 is punching the workpiece, the push rod motor 7 is started, and the output shaft of the push rod motor 7 drives the lifting plate 6 to move up and down. The lifting of the lifting plate 6 can drive the mold 14 to move up and down. The lifting of the mold 14 can perform good stamping and forming on the workpiece. When the mold is damaged after long-term use and needs to be replaced, the pull plate 25 and the slide plate 17 are pulled so that the wedge block 18 moves to the outside of the slot 22 and the second clamping ring 16 does not contact the mounting seat 12. At this time, the limit of the mounting seat 12 can be released, and the disassembly of the mold 14 is completed. When it needs to be installed, the pull plate 26 is pulled , the pull plate 26 drives the second clamping ring 16 to move, and at this time pushes the mounting seat 12, and the mounting seat 12 squeezes the wedge block 18, so that the wedge block 18 moves, and the wedge block 18 moves to squeeze the fourth spring 21, so that the fourth spring 21 is in a compressed state. When the wedge block 18 and the card slot 22 are located on the same axis, the wedge block 18 will slide into the card slot 22 under the elastic force of the fourth spring 21, which can preliminarily limit the mounting seat 12. At this time, by loosening the pull plate 26, the second clamping ring 16 will complete the further clamping of the mounting seat 12, thereby completing the installation of the mounting seat 12.

[0028] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
