Description

Technical Field

[0001] The utility model provides a metal product mold facilitating demolding, belonging to the technical field of metal product molds. Background Art

[0002] Metal product molds are key tools for manufacturing metal products and are widely used in processes such as casting, forging, and stamping. The design and manufacturing of molds require high precision to ensure the accurate size and shape of the final product. Metal product molds are usually made of high-strength alloy steel and can withstand high-temperature and high-pressure working environments. During the manufacturing process, the molds are fabricated through precision machining techniques to meet the shape and size requirements of specific products. The application scope of metal product molds is extensive, including automotive parts, mechanical accessories, hardware products, etc. The metal products manufactured through molds not only have an attractive appearance but also possess good mechanical properties.

[0003] Currently, when metal parts are produced using stamping molds, since the surface of the part material adheres to the punch and the die, it is prone to die clamping during demolding. At this time, workers need to use external force for demolding, which is likely to damage the parts. Moreover, during stamping, the material rubs against the die. After being used for a period of time, the die will become hot, resulting in a smaller gap between the molds, thus affecting the precision of the processed products. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is that when die clamping occurs in the current stamping mold, it is not easy to demold, and after the stamping mold is used for a period of time, it affects the precision of the processed products.

[0010] As an improvement, the cylinder is arranged inside the base, and there is a second hole on the upper end surface of the base and the flat part of the female die for the cylinder shaft of the cylinder to pass through;

[0011] As an improvement, when the cylinder shaft of the cylinder shortens, the end face of the cylinder shaft is on the same plane as the flat part of the female die, and when the cylinder shaft of the cylinder extends, the end of the cylinder shaft is above the upper end of the female die.

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

[0020] The present utility model will be further described below with reference to the drawings.

[0021] According to Figure 1— As shown in Figure 5: The present utility model provides a metal product mold facilitating demolding, which includes a hydraulic press 1, a punch 2 and a die 3 installed on the hydraulic press 1. A push rod 4 passing through the punch 2 is provided at the upper part of the hydraulic press 1, and a cylinder 5 with a cylinder shaft passing through the die 3 is provided at the lower part of the hydraulic press 1. A through cooling pipe 6 is provided in the die 3. Coolant tanks 7 are respectively provided at both ends of the cooling pipe 6. Refrigeration plates 8 are respectively provided in the two coolant tanks 7 and are connected through a connecting pipe 9. A pump body 10 is provided in the middle of the connecting pipe 9. By providing the push rod 4, the metal parts stuck on the punch 2 can be pushed down. By providing the cylinder 5, the metal parts stuck in the die 3 can be pushed out. By providing the pump body 10 to drive the circulation of the coolant in the two coolant tanks 7 and the cooling pipe 6, the die 3 can be continuously cooled, so that the gap between the punch 2 and the die 3 will not be changed.

[0022] According to Figure 1 , 2 、As shown in Figure 3: The hydraulic press 1 includes a base 101, support rods 102 provided at the four corners above the base 101, hydraulic cylinders 103 provided at the upper ends of the four support rods 102, a hydraulic rod 104 provided in the middle below the hydraulic cylinders 103, and a mounting platform 105 provided at the lower end of the hydraulic rod 104. The punch 2 is installed in the middle below the mounting platform 105, and the die 3 is installed in the middle above the base 101. A hole 401 for the push rod 4 to pass through is provided in the flat parts of the mounting platform 105 and the die 3. When the hydraulic rod 104 extends, the lower end of the push rod 4 is inside the mounting platform 105. When the hydraulic rod 104 shortens, the lower end of the push rod 4 is below the punch 2. After placing the material on the die 3, extending the hydraulic rod 104 can make the mounting platform 105 drive the punch 2 to descend to realize the stamping operation. Then, contracting the hydraulic rod 104 can make the punch 2 reset. When descending, the push rod 4 does not protrude from the punch 2, so as not to affect the stamping operation. After stamping, if the parts are stuck on the punch 2, when the hydraulic rod 104 contracts and the mounting platform 105 drives the punch 2 to gradually rise, the push rod 4 will gradually protrude from the punch 2, so that the parts can be pushed out from the punch 2.

[0023] According to Figure 4 As shown: The cylinder 5 is provided inside the base 101. A hole 501 for the cylinder shaft of the cylinder 5 to pass through is provided between the upper end surface of the base 101 and the flat part of the die 3. When the cylinder shaft of the cylinder 5 shortens, the end surface of the cylinder shaft is on the same plane as the flat part of the die 3. When the cylinder shaft of the cylinder 5 extends, the end of the cylinder shaft is above the upper end of the die 3. In this way, during stamping, the cylinder shaft of the cylinder 5 will not affect the stamping effect. After stamping, if the parts are stuck in the die 3, extending the cylinder shaft of the cylinder 5 can make the cylinder shaft, and the cylinder shaft of the cylinder 5 will protrude from the die 3, so that the parts can be pushed out from the die 3.

[0024] Principle of the present utility model: During use, first start the pump body 10 and the refrigeration plate 8. The refrigeration plate 8 keeps the coolant at a relatively low temperature all the time, and the pump body 10 circulates the coolant in the cooling pipe 6, two cooling boxes 7, and the connecting pipe 9 to achieve the circulating cooling of the female die 3. Then place the material on the female die 3, and then extend the hydraulic rod 104 to drive the punch 2 to descend by the mounting platform 105 to achieve the stamping operation. Finally, retracting the hydraulic rod 104 can reset the punch 2, and thus a part is stamped. If the part gets stuck on the punch 2, when the hydraulic rod 104 retracts and the mounting platform 105 drives the punch 2 to gradually rise, the push rod 4 will gradually protrude from the punch 2, so that the part can be pushed out from the punch 2. If the part gets stuck on the female die 3, then start the cylinder 5 to make the cylinder shaft of the cylinder 5 protrude from the female die 3, so that the part can be pushed out from the female die 3.

[0025] The above describes the present utility model and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. All in all, if those of ordinary skill in the art are inspired by it and design similar structural manners and embodiments without creative efforts without departing from the creative purpose of the present utility model, they shall fall within the protection scope of the present utility model.
