Description

Technical Field

[0001] The utility model belongs to the technical field of easy-open lid production, and in particular relates to an easy-open lid production mould. Background Art

[0002] Cans are easy to carry and use, and are very popular among consumers. Beverage or food cans are usually composed of a can body and a can lid. The can lid consists of a cover plate, rivets, a pull ring and a score on the cover plate. The can lid covers the opening of the can body and is sealed around the can body. The score line on the cover plate is a continuous and closed score, which is the opening of the cover plate when the can is opened. The pull ring consists of a finger ring, a pull ring plate and a rivet hole. The rivet hole is located on the pull ring plate. There is a small protrusion in the front center of the pull ring plate, and the rivet hole is close to the protrusion. When opening the can, pull up the finger ring so that the protrusion of the pull ring plate presses the score line on the cover plate. The cover plate cracks a small hole from the weak link of the score line. Then pull the pull ring, and the crack extends forward along the score line until the closed score line is completely opened. At this time, the cover plate in the score line is pulled off by the pull ring along the score line, and the can is opened, and the beverage or food in the can can be eaten.

[0003] At present, cans are generally opened by pulling the pull ring on the open lid. The production of the open lid is mainly through mold stamping. When the traditional stamping mold is used, the open lid is easy to remain inside the mold after stamping, resulting in the problem of jamming and difficulty in removal, which in turn affects the subsequent stamping processing of the open lid. Utility Model Content

[0004] The utility model aims to provide a production mould for an easy-open lid to solve the problems raised in the above-mentioned background technology.

[0007] A movable plate is slidably mounted between the outer edge surfaces of the support rods, a die structure is movably mounted in the center of the lower end surface of the movable plate, the die structure comprises a lower pressing block symmetrically provided with mounting grooves inside, an upper mold is movably mounted below the lower pressing block, lower pressing rods are fixedly mounted on both sides of the upper end surface of the upper mold, the top end of the lower pressing rods extends into the mounting groove and is fixedly connected to a limiting block, a spring is fixedly mounted on the top of the limiting block, the top end of the spring is fixedly connected to the top wall of the mounting groove, and a lower mold adapted to be pressed into the upper mold is centrally constructed on the top of the processing table.

[0008] Furthermore, a positioning groove is centrally provided on the lower end surface of the movable plate, and an electric motor is fixedly installed at one end of the movable plate. The electric motor is connected to a ball screw centrally rotatably installed in the positioning groove through a motor shaft, and a slider is movably installed on the outer edge surface of the ball screw, and the lower end surface of the slider is fixedly connected to the upper end surface of the lower pressure block.

DETAILED DESCRIPTION

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0018] like Figure 1-Figure 3 As shown, the easy-open lid production mold includes a processing table 1 with support rods 6 fixedly installed at the four corners of the upper end surface, a movable plate 9 is slidably installed between the outer edge surfaces of the support rods 6, and a die structure is movably installed in the center of the lower end surface of the movable plate 9. The die structure includes a lower pressing block 14 with a mounting groove 15 symmetrically opened inside, an upper mold 19 is movably installed below the lower pressing block 14, and lower pressing rods 18 are fixedly installed on both sides of the upper end surface of the upper mold 19. The top of the lower pressing rod 18 extends into the mounting groove 15 and is fixedly connected to a limiting block 17. A spring 16 is fixedly installed on the top of the limiting block 17, and the top of the spring 16 is fixedly connected to the mounting groove 15. The top wall of the groove 15 and the top center of the processing table 1 are constructed with a lower mold adapted to be pressed into the upper mold 19. Thanks to the arrangement of the processing table 1, the support rod 6, the movable plate 9, the lower pressure block 14, the mounting groove 15, the spring 16, the limit block 17, the lower pressure rod 18 and the upper mold 19, when the easy-pull cover is stamped by the die structure, the upper mold 19 abuts against the surface of the workpiece and extends into the lower mold, so that the spring 16 is compressed and deformed through the reaction force. After the easy-pull cover is stamped, the elastic force of the spring 16 is released and pushes the upper mold 19 to move during the retraction of the die structure, thereby pushing the easy-pull cover to fall through the upper mold 19.

[0019] like Figure 1-Figure 3 As shown, a positioning groove 10 is centrally provided on the lower end surface of the movable plate 9, and a motor 11 is fixedly installed at one end of the movable plate 9. The motor 11 is connected to a ball screw 12 which can be centrally rotatably installed in the positioning groove 10 through a motor shaft. A slider 13 is movably installed on the outer edge surface of the ball screw 12, and the lower end surface of the slider 13 is fixedly connected to the upper end surface of the lower pressure block 14.

[0020] like Figure 1 and Figure 2 As shown, a storage bin 3 is provided in the processing table 1, a storage drawer 4 is movably installed in the storage bin 3, a handle 5 is fixedly installed in the center of one side of the storage drawer 4, a mold groove connected to the storage bin 3 is provided at the bottom of the lower mold, and supporting feet 2 are provided at the four corners of the lower end surface of the processing table 1, and the top end structure of the supporting feet 2 is connected to the lower end surface of the processing table 1.

[0021] like Figure 1 As shown, the top end structure of the support rod 6 is connected to a bearing platform 7, and hydraulic push rods 8 are fixedly installed on both sides of the upper end surface of the bearing platform 7. The rod of the hydraulic push rod 8 extends out of the bearing platform 7 and is fixedly connected to the upper end surface of the movable plate 9.

[0022] Working principle: When the easy-pull cover production mold is used, the workpiece is placed on the processing table 1, and then the hydraulic push rod 8 is started to extend the rod of the hydraulic push rod 8 and push the movable plate 9 downward. When the easy-pull cover is stamped through the die structure, the upper mold 19 abuts against the surface of the workpiece and extends into the lower mold, so that the spring 16 is compressed and deformed through the reaction force. After the easy-pull cover is stamped, the elastic force of the spring 16 is released and pushes the upper mold 19 to move during the retraction of the die structure, thereby pushing the easy-pull cover to fall through the upper mold 19, and the easy-pull cover falls into the storage bin 3 through the die groove. Then, the storage drawer 4 can be pulled out of the storage bin 3 by pulling the handle 5, so that the easy-pull cover in the storage drawer 4 can be taken out conveniently. The easy-pull cover production mold has a reasonable structure, is convenient for pushing out the easy-pull cover during the stamping process, and avoids jamming. It is highly practical.
