The working process of the metal stamping die is as follows: feed the bar to be punched along the guide pin 24 to the stopper pin 20, and the upper die descends through the punch punches 5, 11, 12 Punching of 2 Φ8.5 mm holes, 5 Φ7 mm holes, and 2 curved holes with a length of 45 mm and a width of 8.5 mm was completed, and blanking of the bracket was completed at the same time.

The punching waste of the mold is discharged by the pushing method, and the punching action of the metal stamping die press is used to complete the punching. The overlapped waste material adopts an elastic discharge method. While the upper die is punched down, the discharge plate 25 pushes the rubber 18 to produce compression deformation, and the discharge plate 25 generates a downward relative displacement with respect to the convex and concave die 17. When the upper die moves upward, the rubber 18 rebounds, causing the discharge plate 25 to move upward relative to the male and female die 17, which drives the edge scraps buckled on the male and female die 17 to move upward, so that the edge scraps are separated from the male and female die 17 to complete the unloading. material. The punched parts remaining in the die 16 are discharged by the punch 8 of the rigid push device, the punch 9, the push rod 10, and the push plate 26 by the return motion of the press. At this point, a punching process is completed, and the strip to be punched is continuously fed along the guide pin 24 to the stopper pin 20 for the next punching process.

As the production time continues, the mold cooling channel of the steel cabinet file cabinet is prone to deposit scale, rust, silt and algae, which makes the cross section of the cooling channel smaller and the cooling channel narrower, which greatly reduces the heat exchange rate between the cooling liquid and the mold. Increasing the production cost of the enterprise, so attention should be paid to the cleaning of the runner; for the hot runner mold, the maintenance of the heating and control system is helpful to prevent the occurrence of production failures, so it is particularly important. Therefore, after the end of each production cycle, the belt heater, rod heater, heating probe, and thermocouple on the mold should be measured with an ohmmeter. If it is damaged, it should be replaced in time and carried out with the mold resume. Compare and make records so that problems can be identified in a timely manner and countermeasures can be taken.

Pay attention to the surface maintenance of the mold, it directly affects the surface quality of the product, and the focus is on preventing rust. Therefore, it is especially important to choose a suitable, high-quality, professional anti-rust oil. After the steel office furniture stamping mold has completed the production task, different methods should be used to carefully remove residual injection molding according to different injection molding. Copper rods, copper wires and professional mold cleaning agents can be used to remove residual injection molding and other deposits in the mold, and then air-dried. Do not clean hard objects such as iron wires and steel bars to avoid scratching the surface. If there are rust spots caused by corrosive injection molding, use a grinder to grind and polish, and spray professional anti-rust oil, and then store the mold in a dry, cool, and dust-free place.

Because the materials of office furniture are different, different materials are needed in the production process of office furniture mold manufacturers, such as sheet materials, plastic materials, accessories materials, hardware materials, and so on. Make and process molds according to the needs of different products. The combined unit parts required for different products such as desks, office chairs, screens, conference tables, etc. are very different. So what are the classifications of steel office furniture stamping dies?

The three major manufacturing shapes of steel office furniture stamping molds can be divided into three categories according to the different types of molds:

Large nozzle: The runner and gate are on the parting line and demoulded together with the product when the mold is opened. The design is the simplest, easy to process, and the cost is low, so most people use the steel nozzle for office furniture stamping. The mold is operated.

Nozzle mold: The runner and gate of this type of steel office furniture stamping mold are not on the parting line, and are usually directly on the product, so it is necessary to design an additional set of nozzle parting line. The design is more complicated and the processing is more difficult. Generally, the nozzle system should be selected according to the product requirements.

Hot runner mold: The structure of this type of mold is roughly the same as that of the sprue. The difference is that the runner is located in one or more hot runner plates and hot nozzles with constant temperature. There is no cold material demoulding in stamping automation, and the runner and gate are directly In terms of products, the flow channel does not need to be demoulded. This system is also known as the nozzleless system, which can save raw materials. It is suitable for situations where the raw materials are expensive and the product requirements are high. The design and processing are difficult and the mold cost is high.
