[0002] A food can is a filling item used to package food, and a food can stamping die is a die specifically used to make food cans. It uses a stamping process to process metal sheets into cans of the desired shape and size, so that it can package different foods.

[0003] A multi-process composite molding die for a food can body with application number CN202022415108.0 comprises a die seat, a cavity is provided inside the die seat, a die block is slidably connected inside the die cavity, a support plate is fixedly connected to the lower end of the die block, a support rod is fixedly connected to the lower end of the support plate, a sleeve is connected to the lower end of the die seat by bolts, a spring is provided inside the sleeve, the upper end of the spring is fixedly connected to the lower end of the support rod, the lower end of the spring is in contact with the inner bottom of the sleeve, and a cutting groove is provided on the die seat. The utility model adds structures such as a spring, a support rod and a die block inside the die seat, so that after the stamping of the food can is completed and the stamping hammer is separated from the die seat, the stamped food can can be lifted from the inside of the cavity under the push of the elastic force of the spring, so that it can be easily taken out.

[0004] By adding a cutting knife and other structures to the lower end of the punching block, the device can cut off excess waste material at the edge of the plate at the end of the punching, thereby eliminating the need to take out the food can and perform edge trimming again. However, the device does not have a positioning device during punching, and when the upper mold moves downward, it is very easy for a position deviation to occur with the mold cavity at the lower end. If a position deviation occurs, it is very easy to cause the workpiece inside the mold cavity to deform, thereby affecting the use of the workpiece.

[0005] In view of the above problems, it is urgent to carry out innovative design based on the original food can stamping die structure. Utility Model Content

[0006] The purpose of the utility model is to provide a food can stamping die to solve the problem proposed in the above background technology that the device is not provided with a positioning device during stamping, and when the upper die moves downward, it is very easy to have a position deviation with the die cavity at the lower end. If a position deviation occurs, it is very easy to cause the workpiece inside the die cavity to deform, thereby affecting the use of the workpiece.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a food can stamping die, comprising a base, and a support leg is fixedly installed at the lower end of the base;

[0008] It also includes: a mold cavity is opened on the inner side of the base, and a positioning hole is opened on the inner side of the base, a support frame is fixedly installed on the upper end of the base, and the support frame is an inverted "L" shape structure when viewed from the side, an electric telescopic rod is fixedly installed on the inner side of the support frame, and an upper mold is fixedly installed on the output end of the electric telescopic rod, a fixed plate is fixedly installed on the outer side of the upper mold, and a positioning rod is fixedly installed on the bottom of the fixed plate, a buffer spring is fixedly installed on the outer side of the positioning rod, and a gasket is fixedly connected to the tail end of the buffer spring, and the gasket is nested on the outer side of the positioning rod.

[0009] Preferably, two groups of positioning holes are symmetrically arranged about the midpoint of the base, and the positioning holes and the positioning rods are distributed correspondingly up and down; this structure positions the upper mold by inserting the positioning rods into the positioning holes.

[0010] Preferably, the gasket and the positioning rod form a sliding structure, and the gasket and the positioning rod form an elastic structure through a buffer spring; this structure in which the gasket and the positioning rod form an elastic structure through a buffer spring can buffer the downward impact force through the elastic force of the buffer spring.

[0011] Preferably, the upper mold and the mold cavity are distributed in correspondence with each other up and down, and the outer dimensions of the upper mold are consistent with those of the mold cavity.

[0012] Preferably, a through groove is opened on the inner side of the base, and the through groove and the inner side of the mold cavity are a through structure; this structure that the through groove and the inner side of the mold cavity are a through structure can enable the ejector frame to eject the workpiece inside the mold cavity.

[0013] Preferably, a servo motor is fixedly installed at the bottom of the base, and a threaded rod is fixedly installed at the output end of the servo motor, a threaded connector is threadedly connected to the outer side of the threaded rod, and a top frame is fixedly installed on the outer side of the threaded connector, and the top frame passes through the inner side of the through groove; this structure can drive the threaded connector threaded on the outer side to move upward by rotating the threaded rod.

[0015] Compared with the prior art, the beneficial effect of the utility model is that the food can stamping die is provided with:

[0016] 1. Positioning structure. When the food can needs to be stamped, the electric telescopic rod is first operated, so that the output end of the electric telescopic rod drives the upper mold to move downward to stamp the workpiece inside the mold cavity;

[0017] Furthermore, when the upper mold moves downward, the fixed plates at both ends will be driven to move downward at the same time. When the fixed plates move downward, the positioning rods are inserted into the inner side of the positioning holes for positioning, thereby preventing the upper mold from having position deviation with the mold cavity when moving downward, causing deformation of the workpiece.

[0018] Furthermore, when the positioning rod moves downward, the gasket at the bottom thereof is squeezed by the upper surface of the base to compress the buffer spring, thereby providing a buffer through the elastic force of the buffer spring to prevent the upper mold from moving downward too quickly and causing excessive impact force;

[0019] 2. Demolding structure: After the workpiece is stamped, the servo motor is operated, and the output end of the servo motor drives the threaded rod to rotate. The rotation of the threaded rod drives the threaded connector connected to the outer thread to move upward, thereby driving the upper frame to move upward through the upward movement of the threaded connector, and ejecting the workpiece inside the mold cavity, thereby achieving a convenient demoulding effect;

[0020] Furthermore, when the top frame moves upward, the sliding rod on its outer side will also slide along the inner side of the sliding track, so that the sliding of the sliding rod on the inner side of the sliding track can limit the angle of the top frame and improve its up and down stability.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] The utility model provides the following technical solutions:

[0031] Embodiment 1: Figure 1-Figure 5 The technical solution shown: a food can stamping mold, disclosed: a base 1, and a support leg 2 is fixedly installed at the lower end of the base 1;

[0032] It also includes: a mold cavity 3 is opened on the inner side of the base 1, and a positioning hole 4 is opened on the inner side of the base 1, a support frame 5 is fixedly installed on the upper end of the base 1, and the support frame 5 is an inverted "L" shape structure when viewed from the side, an electric telescopic rod 6 is fixedly installed on the inner side of the support frame 5, and an upper mold 7 is fixedly installed on the output end of the electric telescopic rod 6, a fixed plate 8 is fixedly installed on the outer side of the upper mold 7, and a positioning rod 9 is fixedly installed on the bottom of the fixed plate 8, a buffer spring 10 is fixedly installed on the outer side of the positioning rod 9, and a gasket 11 is fixedly connected to the tail end of the buffer spring 10, and the gasket 11 is nested on the outer side of the positioning rod 9;

[0033] Two groups of positioning holes 4 are symmetrically arranged about the midpoint of the base 1, and the positioning holes 4 and the positioning rods 9 are distributed in correspondence with each other up and down; the gasket 11 and the positioning rods 9 form a sliding structure, and the gasket 11 and the positioning rods 9 form an elastic structure through the buffer spring 10; the upper mold 7 and the mold cavity 3 are distributed in correspondence with each other up and down, and the outer dimensions of the upper mold 7 are consistent with the outer dimensions of the mold cavity 3;

[0034] When the food can needs to be stamped, this structure first operates the electric telescopic rod 6, so that the output end of the electric telescopic rod 6 drives the upper mold 7 to move downward, and the workpiece inside the mold cavity 3 is stamped. When the upper mold 7 moves downward, it will simultaneously drive the fixed plates 8 at both ends to move downward. When the fixed plates 8 move downward, the positioning rod 9 is inserted into the inner side of the positioning hole 4 for positioning, so as to avoid position deviation between the upper mold 7 and the mold cavity 3 when it moves downward, causing deformation of the workpiece, and when the positioning rod 9 moves downward, the gasket 11 at the bottom thereof is squeezed by the upper surface of the base 1 to compress the buffer spring 10, thereby buffering through the elastic force of the buffer spring 10 to avoid excessive impact force caused by too fast downward movement of the upper mold 7.

[0035] Embodiment 2 is different from Embodiment 1 in that a structure for facilitating demoulding is added on the basis of positioning the upper mold 7, such as Figure 1-Figure 2 , Figure 6 The figure discloses: a through slot 16 is opened on the inner side of the base 1, and the through slot 16 and the inner side of the mold cavity 3 are in a through structure; a servo motor 12 is fixedly installed on the bottom of the base 1, and a threaded rod 13 is fixedly installed on the output end of the servo motor 12, a threaded connector 14 is threadedly connected to the outer side of the threaded rod 13, and a top frame 15 is fixedly installed on the outer side of the threaded connector 14, and the top frame 15 passes through the inner side of the through slot 16;

[0036] After the workpiece is stamped, the servo motor 12 is operated. The output end of the servo motor 12 drives the threaded rod 13 to rotate. The rotation of the threaded rod 13 drives the threaded connector 14 connected to the outer thread to move upward. The threaded connector 14 moves upward, and the upper frame 15 is driven to move upward to eject the workpiece inside the mold cavity 3, thereby achieving a convenient demoulding effect.

[0037] Embodiment 3 is different from Embodiment 2 in that an angle limiting structure is added on the basis of facilitating demoulding, such as Figure 1-Figure 2 , Figure 7 It is disclosed as follows: a sliding rod 17 is fixedly installed on the outside of the threaded connector 14, and the sliding rod 17 is nested inside the sliding track 18, and the sliding track 18 is opened inside the through slot 16;

[0038] When the top frame 15 of this structure moves upward, the sliding rod 17 on its outside will also slide along the inside of the sliding track 18, so that the sliding of the sliding rod 17 on the inside of the sliding track 18 can limit the angle of the top frame 15 and improve its up and down stability.
