Description

Technical Field

[0001] This invention relates to the field of mold technology, and in particular to a waste discharge device for a strip external punching composite forming mold. Background Technology

[0002] Molds are forming tools used in industrial production to mass-produce products. They give products specific shapes and sizes by changing the physical state of materials. They are widely used in blanking, die forging, cold heading, extrusion, powder metallurgy pressing, pressure casting, and compression or injection molding of engineering plastics, rubber, ceramics and other products.

[0003] Currently, for the scrap removal of strip forging composite forming dies, a set of air nozzles is usually set on the side of the die. When the scrap is ejected after the die is opened, air is blown to blow the scrap to the outside of the die. When there are many scrap locations, the scrap may not be completely removed, and manual air blowing is required. If the die is closed before the scrap is completely removed, it will cause material stacking and may even damage the die, affecting safe production. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a waste discharge device for strip external punching composite forming molds.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A waste discharge device for a strip forging composite forming die includes an upper die plate, an intermediate plate, and a lower die base. An upper pad is fixed to the bottom of the upper die plate, a gear ring plate is fixed to the bottom of the intermediate plate, and a limit plate is fixed inside the intermediate plate. A guiding mechanism is provided between the upper die plate, the intermediate plate, and the lower die base. A lower pad is fixed to the top of the lower die base, a lower fixing plate is fixed to the top of the lower pad, and a concave die plate is installed on the top of the lower fixing plate. The limit plate and the gear ring plate have corresponding openings. The mounting port is interconnected, and a punch and die are fixed inside the mounting port. A cavity is opened in the punch and die. A first air outlet is opened in the upper pad plate. The air outlet is connected to the cavity. Here, a cavity for accommodating waste material is left in the punch and die. The air outlet is machined in the upper pad plate and connected to the cavity in the punch and die. After each punching, the waste material enters the cavity of the punch and die one after another. When the waste material rises into the air outlet of the upper pad plate, it is blown out to the outside of the mold by compressed air, and then sent out to the outside of the machine tool by the auxiliary conveying mechanism.

[0006] As a further embodiment of the present invention, the guiding mechanism includes a guide rod fixed to the top of the upper template, a flange guide sleeve fixed in the intermediate plate, a guide sleeve fixed in the lower mold base, and a ball bearing guide sleeve between the guide rod and the guide sleeve. Example

[0007] Reference Figure 3 and6 The gear ring plate has a second air outlet. Four floating air nozzles are arranged on the lower surface of the gear ring plate facing the waste material. The second air outlet is connected to the floating air nozzles. The top of the upper template has an installation channel, which is set to correspond to the position of the punch and die. A punching rod is installed in the installation channel. An air outlet is machined in the gear ring plate here, and four floating air nozzles are arranged on the lower surface of the gear ring plate facing the waste material. After each punching, when the waste material is pushed out by the punching rod to the lower surface of the gear ring plate, it is blown out by the compressed air in the air nozzles to the outside of the die, and then sent out to the machine tool by the auxiliary conveying mechanism. Example

[0008] Reference Figure 4 and 7 The upper surface of the concave template is provided with a ramp at the part discharge position. Here, a ramp is provided on the upper surface of the concave template at the part discharge position. After each punching, the part is conveyed to the ramp position and slides out of the outside of the mold along the ramp, and is then sent out of the machine tool by the auxiliary conveying mechanism.

[0009] The beneficial effects of this invention are as follows: This invention utilizes three discharge methods to smoothly discharge waste materials from different locations to the outside of the mold, ensuring safe production and improving production efficiency. Attached Figure Description
