Description

Technical Field

[0001] The utility model relates to the field of hardware molds, in particular to a hardware mold facilitating demolding. Background Art

[0002] Hardware generally refers to the collective name of five metal materials. However, in different fields and regions, its specific meaning may vary. Traditional hardware refers to five metals: gold, silver, copper, iron, and tin. The modern term "hardware" more widely refers to metal or non-metal products, including various metal devices made by physical processing such as forging, rolling, and cutting of metals such as iron, steel, and aluminum. Hardware tools refer to the general name of various metal devices made by physical processing such as forging, rolling, and cutting of metals such as iron, steel, and aluminum. A hardware mold is a special tool used in industrial production to manufacture parts or products of the required shape from metal materials by applying pressure with various presses and special tools installed on the presses. Existing hardware molds usually require manual assistance for demolding after stamping, with cumbersome operations and low demolding efficiency. Content of the Utility Model

[0003] In order to overcome the problem that existing hardware molds usually require manual assistance for demolding after stamping, with cumbersome operations and low demolding efficiency.

[0004] The technical solution of the utility model is as follows: A hardware mold facilitating demolding, comprising a workbench, a stamping assembly, a demolding assembly, a pushing assembly, a die groove, a punch, a foot column, a base, and an anti-slip pad. In the middle of the upper end of the workbench, a stamping assembly for stamping and forming metal is fixedly installed. At the bottom of the workbench, a demolding assembly for ejecting the formed hardware is fixedly installed. At the side of the upper end of the workbench, a pushing assembly for pushing the ejected hardware to the side is fixedly installed. Three die grooves with different shapes for installing punches are evenly arranged in the middle of the upper end of the workbench. At the bottoms of the three die grooves, punches with different shapes for cooperating with the stamping assembly to stamp and form metal are respectively fixedly installed. At the four corners of the lower end of the workbench, foot columns for supporting the workbench are fixedly installed around. The lower ends of the foot columns are fixedly connected to a base for increasing the support stability. An anti-slip pad for increasing friction is attached to the lower end of the base.

[0005] Preferably, by setting the stamping assembly, the metal sheet can be stamped into a corresponding shape in cooperation with the punch in the die groove. By setting the pushing assembly, the demolding structure ejected by the demolding assembly can be pushed to one side of the workbench, facilitating the removal of the demolding structure and transporting it to the corresponding position. With the mutual cooperation of the demolding assembly and the pushing assembly, rapid demolding can be achieved, thus greatly improving work efficiency.

[0006] Preferably, the stamping assembly includes a support frame, a pressing plate, hydraulic rods, a hydraulic cylinder, and a female die. A pressing plate for stamping is provided below the support frame. The upper end of the pressing plate is adjustably connected to the support frame through three groups of evenly distributed hydraulic rods. Three groups of female dies with different shapes for forming are evenly arranged at the lower end of the pressing plate.

[0007] Preferably, the hydraulic cylinder is provided with an output shaft. The output shaft of the hydraulic cylinder passes through the upper end of the support frame and extends to the lower end to control the up and down movement of the hydraulic rods. By controlling the hydraulic rods with the hydraulic cylinder to drive the female die to move downward, the metal sheet can be stamped into a hardware structure with a corresponding shape in cooperation with the male die.

[0008] Preferably, the demoulding assembly includes a first ejector block, a second ejector block, a third ejector block, a first electric push rod, and a first telescopic cylinder. The first ejector block, the second ejector block, and the third ejector block are respectively sleeved outside three groups of male dies and placed at the bottom of the die groove. The lower ends of the first ejector block, the second ejector block, and the third ejector block are fixedly connected in a left-right symmetric manner with a first electric push rod for controlling their up and down movement.

[0009] Preferably, the first ejector block, the second ejector block, and the third ejector block are all adjustably connected to the first telescopic cylinder through the first electric push rod. The first telescopic cylinder drives the first ejector block, the second ejector block, and the third ejector block to move synchronously by controlling the up and down movement of the first electric push rod. By controlling the first electric push rod with the first telescopic cylinder to drive the first ejector block, the second ejector block, and the third ejector block to move upward, the demoulding structure can be ejected from the die groove.

[0010] Preferably, the pushing assembly includes a mounting plate, a second electric push rod, a second telescopic cylinder, a pushing block, and a protective layer. Three groups of second electric push rods for controlling the movement of the pushing block are evenly arranged at one end of the mounting plate close to the middle of the workbench. The end of the second electric push rod away from the mounting plate is fixedly connected with a pushing block for pushing the formed hardware. By providing a pushing block controlled by the second electric push rod, the demoulding structure after demoulding can be pushed to a corresponding position, so as to facilitate removing the demoulding structure and transporting it to the corresponding position.

[0011] Preferably, a protective layer for protecting the hardware parts is attached to the outside of the pushing block. The second telescopic cylinder is provided with an output shaft. The output shaft of the second telescopic cylinder passes through one side of the mounting plate and extends to the other side to control the movement of the second electric push rod. By providing a protective layer to protect the hardware parts formed by demoulding, it can be avoided that the hardware parts are damaged due to excessive force.

[0012] The beneficial effects of the present utility model:

[0013] 1. Compared with traditional hardware molds, manual assistance is usually required for demolding after stamping forming. The operation is rather cumbersome and the demolding efficiency is low. By setting up a demolding component, the formed demolding structure can be automatically pushed out after the mold stamping forming, without manual operation, which is more time-saving and labor-saving. By setting up a first telescopic cylinder, the first electric push rod can be controlled to drive the first ejector block, the second ejector block and the third ejector block to move up and down. Thus, the demolding structure can be automatically pushed out of the mold cavity by controlling the upward movement of the first ejector block, the second ejector block and the third ejector block. Demolding by using the first telescopic cylinder to control the automatic pushing out of the demolding structure is more time-saving and labor-saving than manual operation.

[0014] 2. By setting up a pushing component, the demolding structure ejected by the demolding component can be pushed to one side of the workbench, thus facilitating the removal of the demolding structure and transporting it to the corresponding position. By setting up a second telescopic cylinder, the second electric push rod can be controlled to drive the push block to move, so that the push block can push the relevant demolding structure to the corresponding position, thus making it more convenient to remove the product. With the mutual cooperation of the demolding component and the pushing component, rapid demolding can be achieved, thus greatly improving the work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0022] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] Please refer to Figures 1-3 , the present utility model provides an embodiment: a hardware mold convenient for demolding, including a workbench 1, a stamping assembly 2, a demolding assembly 3, a pushing assembly 4, a die groove 5, a punch 6, a foot post 7, a base 8 and an anti-slip pad 9. In the middle of the upper end of the workbench 1, a stamping assembly 2 for stamping and forming metal is fixedly installed. At the bottom of the workbench 1, a demolding assembly 3 for ejecting the formed hardware is fixedly installed. At the side of the upper end of the workbench 1, a pushing assembly 4 for pushing the ejected hardware to the side is fixedly installed. Three groups of die grooves 5 with different shapes for installing the punch 6 are evenly arranged in the middle of the upper end of the workbench 1. At the bottoms of the three groups of die grooves 5, punches 6 with different shapes for cooperating with the stamping assembly 2 to stamp and form metal are respectively fixedly installed. At the four corners of the lower end of the workbench 1, foot posts 7 for supporting the workbench 1 are fixedly installed around. At the lower end of the foot post 7, a base 8 for increasing the support stability is fixedly connected. At the lower end of the base 8, an anti-slip pad 9 for increasing friction is attached.

[0024] Please refer to Figure 4 In this embodiment, the stamping assembly 2 includes a support frame 201, a pressing plate 202, a hydraulic rod 203, a hydraulic cylinder 204 and a female die 205. Below the support frame 201, a pressing plate 202 for stamping is provided. The upper end of the pressing plate 202 is adjustably connected to the support frame 201 through three groups of evenly arranged hydraulic rods 203. At the lower end of the pressing plate 202, three groups of female dies 205 with different shapes for forming are evenly arranged. The hydraulic cylinder 204 is provided with an output shaft. The output shaft of the hydraulic cylinder 204 passes through the upper end of the support frame 201 and extends to the lower end to control the up and down movement of the hydraulic rod 203. By controlling the hydraulic rod 203 by the hydraulic cylinder 204 to drive the female die 205 to move downward, the metal sheet can be stamped into a hardware structure with a corresponding shape in cooperation with the punch 6.

[0025] Please refer to Figure 5, in this embodiment, the demolding assembly 3 includes a first ejector block 301, a second ejector block 302, a third ejector block 303, a first electric push rod 304, and a first telescopic cylinder 305. The first ejector block 301, the second ejector block 302, and the third ejector block 303 are respectively sleeved outside the three groups of convex dies 6 and placed at the bottom of the mold cavity 5. The lower ends of the first ejector block 301, the second ejector block 302, and the third ejector block 303 are fixedly connected in a left-right symmetric manner with a first electric push rod 304 for controlling their up and down movement. The first ejector block 301, the second ejector block 302, and the third ejector block 303 are all adjustably connected to the first telescopic cylinder 305 through the first electric push rod 304. The first telescopic cylinder 305 drives the first ejector block 301, the second ejector block 302, and the third ejector block 303 to move synchronously by controlling the up and down movement of the first electric push rod 304. By controlling the first electric push rod 304 by the first telescopic cylinder 305 to drive the first ejector block 301, the second ejector block 302, and the third ejector block 303 to move upward, the demolding structure can be ejected from the mold cavity 5.

[0026] Please refer to Figure 6 , in this embodiment, the pushing assembly 4 includes a mounting plate 401, a second electric push rod 402, a second telescopic cylinder 403, a push block 404, and a protective layer 405. Three groups of second electric push rods 402 for controlling the movement of the push block 404 are evenly arranged at one end of the mounting plate 401 close to the middle of the workbench 1. One end of the second electric push rod 402 away from the mounting plate 401 is fixedly connected to a push block 404 for pushing the formed hardware. By setting the push block 404 controlled by the second electric push rod 402, the demolded demolding structure can be pushed to the corresponding position, so as to facilitate removing the demolding structure and transporting it to the corresponding position. A protective layer 405 for protecting the hardware parts is attached to the outside of the push block 404. The second telescopic cylinder 403 is provided with an output shaft, and the output shaft of the second telescopic cylinder 403 passes through one side of the mounting plate 401 and extends to the other side to control the movement of the second electric push rod 402. By setting the protective layer 405 to protect the hardware parts formed by demolding, it can be avoided that the hardware parts are damaged due to excessive force.

[0027] When working, first place the base 8 on the corresponding stable ground so that the anti-slip pad 9 at the lower end of the base 8 is in close contact with the ground;

[0028] Then place the metal sheets to be stamped in turn at the positions corresponding to the convex dies 6 outside the three groups of mold cavities 5;

[0029] Then stamp the metal sheets through the stamping assembly 2. The hydraulic cylinder 204 controls the hydraulic rod 203 to drive the pressing plate 202 to move downward, so that the pressing plate 202 drives the concave die 205 to move synchronously to squeeze the metal sheets downward into the mold cavity 5 to form a corresponding-shaped demolding structure;

[0030] Afterwards, the demolding structure formed by stamping is ejected from the mold cavity 5 through the demolding assembly 3. The first electric push rod 304 is driven by the first telescopic cylinder 305 to drive the first ejector block 301, the second ejector block 302, and the third ejector block 303 to move upward to eject the demolding structure from the mold cavity 5.

[0031] Finally, the ejected demolding structure is pushed to one side of the workbench 1 through the pushing assembly 4. The second electric push rod 402 is driven by the second telescopic cylinder 403 to drive the push block 404 to move, so that the push block 404 pushes the relevant demolding structure to the corresponding position, and then the demolding structure can be taken away.

[0032] Through the above steps, the staff first place the base 8 on the corresponding stable ground, so that the anti-slip pad 9 at the lower end of the base 8 is in close contact with the ground. By setting the anti-slip pad 9 at the lower end of the base 8, the friction with the ground can be increased, thereby playing an anti-slip role, making the base 8 not easy to slide or shift. Then, the metal sheets to be stamped are sequentially placed at the positions corresponding to the convex molds 6 outside the three groups of mold cavities 5. Then, the metal sheets are stamped through the stamping assembly 2. The hydraulic rod 203 is driven by the hydraulic cylinder 204 to drive the pressing plate 202 to move downward, so that the pressing plate 202 drives the concave mold 205 to move synchronously to squeeze the metal sheet downward into the mold cavity 5 to form a demolding structure with a corresponding shape. Afterwards, the demolding structure formed by stamping is ejected from the mold cavity 5 through the demolding assembly 3. The first electric push rod 304 is driven by the first telescopic cylinder 305 to drive the first ejector block 301, the second ejector block 302, and the third ejector block 303 to move upward to eject the demolding structure from the mold cavity 5. By setting the demolding assembly 3, the formed demolding structure can be automatically ejected after the mold is stamped, without manual operation, which is more time-saving and labor-saving. Finally, the ejected demolding structure is pushed to one side of the workbench 1 through the pushing assembly 4. The second electric push rod 402 is driven by the second telescopic cylinder 403 to drive the push block 404 to move, so that the push block 404 pushes the relevant demolding structure to the corresponding position, and then the demolding structure can be taken away. By setting the pushing assembly, the demolding structure ejected by the demolding assembly 3 can be pushed to one side of the workbench 1, so as to facilitate taking down the demolding structure and transporting it to the corresponding position. With the mutual cooperation of the demolding assembly 3 and the pushing assembly 4, rapid demolding can be achieved, thereby greatly improving work efficiency.

[0033] The above has described the embodiments of the present invention in detail with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the gist of the present invention.
