Description

Technical Field

[0001] The utility model relates to the technical field of molds for hardware tooling production, in particular to a mold for hardware tooling production which is convenient and quick to form. Background Art

[0002] When hardware tools are produced, pressure is applied to the material at room temperature using a mold installed on a press to deform it into the desired hardware tools. However, after the hardware mold is pressed, it is necessary to wait for the internal material to cool down at room temperature before taking it out, resulting in slow molding efficiency of the hardware tools, affecting the production efficiency of the hardware tools and the lack of fast-molding hardware molds. Utility Model Content

[0003] The technical problem to be solved by the utility model is: in order to overcome the above problems, a mold for hardware tooling production that is convenient for rapid prototyping is provided, which solves the above problems.

[0004] The utility model solves the technical problem by adopting the following technical solutions:

[0005] A mold for hardware tooling production that is convenient for rapid molding, comprising a lower mold base, mold base support arms fixed at the four corners of the upper end of the lower mold base, and an upper mold base fixed at the upper end of the mold base support arms, an upper pressing die that can be pressed downward to form is provided on the lower end surface of the upper mold base, and a molding die for molding is fixed on the upper end surface of the lower mold base;

[0006] It also includes a sliding sleeve that is slidably mounted on the mold base support arm up and down, a connecting plate is connected between the sliding sleeves, and a strip blowing row with a blowing port pointing to the upper end surface of the forming mold is fixed on the inner side of the connecting plate. The strip blowing row is externally connected to the air outlet of the cold air fan through an air supply hose. When the cold air fan is activated, it blows cold air directly to the workpiece after processing to cool it quickly.

[0007] Preferably, an infrared light curtain emitting red light and an infrared light curtain receiver receiving red light are respectively fixed on the inner sides of the other two opposite connecting plates. When the upper die is pressed down, the reception of the infrared light curtain receiver is blocked and the strip blowing row does not blow air. When the upper die is lifted, the infrared light curtain receiver can receive infrared signals normally, allowing the air cooler to work and blow air to cool the workpiece through the strip blowing row.

[0008] Preferably, a pressurized gas tank is also connected in series between the air cooler and the air supply hose, and a solenoid valve for controlling the opening and closing of the exhaust port of the pressurized gas tank is fixedly provided on the pressurized gas tank. During the downward pressing and shaping process of the upper die, the air cooler inflates the pressurized gas tank so that the air in the pressurized gas tank is greater than the standard air pressure. When the upper die is lifted, the infrared light curtain receiver obtains the infrared signal and controls the solenoid valve to be turned on so that the pressurized cold air in the pressurized gas tank is quickly blown toward the stamping part, which can effectively cool it down.

[0009] Preferably, the working gas pressure in the pressurized gas tank is at least two standard atmospheric pressures, so that the fast flow rate of the cooling air is conducive to accelerating the cooling of the workpiece.

[0010] Preferably, a magnetic sleeve is fixedly provided on the inner wall of the sliding sleeve, and the sliding sleeve can slide up and down under the action of external force, and can be fixed at any height of the mold base support arm by magnetic attraction, so that the blowing height of the strip blowing row can be adjusted conveniently and adaptable to molds of different heights.

[0011] Preferably, a threaded hole with a horizontal axis is provided on the sliding sleeve, and a fastening screw is provided on the internal thread connection thereof for fixing the sliding sleeve at a specified height position of the mold base support arm.

[0012] The advantages and positive effects of the utility model are:

[0013] 1. The formed workpiece is quickly cooled down through the cooling and blowing structure, so that the workpiece can shrink in size after cooling and bounce up by itself, making it easier to take out.

[0014] 2. The device has a simple structure, no leakage, good cooling effect, easy maintenance and high degree of automation. BRIEF DESCRIPTION OF THE DRAWINGS
