Metal stamping die stamping parts using a flip-chip composite die structure. It is mainly composed of rigid pushing device, elastic unloading device, positioning parts, punching punch, blanking die, punch and concave die, fixed plate and backing plate.

The working process of the metal stamping die is as follows: the strip to be punched is fed to the stop pin 20 along the guide pin 24, the upper die goes down, and the punching of 2 Φ8.5mm holes, 5 Φ7mm holes and 2 arc holes with a length of 45 mm and a width of 8.5mm is completed through the punching punches 5, 11,12, 17 and 16, at the same time, the blanking and blanking of the bracket are completed.

The punching waste of the die is discharged by pushing out and is completed by the punching action of the metal stamping die press. The side-by-side waste is an elastic discharge method, the upper mold down to complete the cutting at the same time, the discharge plate 25 to push the rubber 18 to produce compression deformation, the discharge plate 25 relative to the convex mold 17 to produce a downward relative displacement. When the upper mold line, the rubber 18 rebound, so that the discharge plate 25 relative to the convex and concave mold 17 to produce upward relative displacement, drive the buckle in the convex and concave mold 17 on the edge of the waste to move upward, so that the edge of the waste from the convex and concave mold 17 to complete the discharge. Stamping parts stored in the concave mold 16, with the help of the return action of the press, by the rigid push device of the rod 8, the plate 9, the push rod 10, the push plate 26 to complete the discharge. At this point, one stamping process is completed, and the to-be-punched strip material continues to be fed along the material guide pin 24 to the material stop pin 20 for the next stamping process.

As the production time continues, the cooling channel of the steel cabinet filing cabinet mold is easy to deposit scale, rust, silt and algae, etc., which makes the cross section of the cooling channel smaller and the cooling channel narrower, greatly reducing the heat exchange rate between the cooling liquid and the mold and increasing the production cost of the enterprise. Therefore, attention should be paid to cleaning the flow channel. For hot runner molds, the maintenance of heating and control systems is especially important to prevent production failures. Therefore, after the end of each production cycle, the band heater, rod heater, heating probe and thermocouple on the mold should be measured with an ohmmeter. If there is any damage, it should be replaced in time, compared with the mold resume, and recorded so as to find problems in time and take countermeasures.

Attention should be paid to the surface maintenance of the mold, which directly affects the surface quality of the product, and the focus is to prevent corrosion. Therefore, it is particularly important to choose a suitable and professional anti-rust oil. When the steel office furniture stamping mold to complete the production task, should be based on different injection molding to take different methods to carefully remove the residual injection molding, available copper rod, copper wire and professional mold cleaning agent to remove the mold residual injection molding and other deposits, and then air dry. Disable cleaning of hard objects such as iron wire and steel bar to avoid scratching the surface. If there are rust spots caused by corrosive injection molding, use a grinding machine to grind and polish, and spray professional anti-rust oil, and then store the mold in a dry, cool, dust-free place.

Because the material of office furniture is different, so the production process of office furniture mold manufacturers need different materials, plate materials, plastic materials, accessories materials, hardware materials and so on. According to the needs of different products need to mold production and processing. The combination of single components required for different products such as bantai, office chairs, screens, conference tables, etc. is very different. So what are the classification of steel office furniture stamping die?

Steel office furniture stamping mold of the three production shape, according to the different type of mold can be divided into three categories:

Large nozzle mold: the runner and gate are on the parting line and demoulded together with the product when the mold is opened. the design is simple, easy to process and the cost is low. therefore, more people use the steel office furniture stamping mold with large nozzle system for operation.

Fine nozzle die: the runner and gate of this type of steel office furniture stamping die are not on the parting line, but are generally directly on the product. therefore, an extra set of nozzle parting lines should be designed, which is more complicated and difficult to process. generally, the fine nozzle system should be selected according to the product requirements.

Hot runner mold: the structure of this kind of mold is basically the same as that of fine nozzle. the difference is that the runner is located in one or more hot runner plates and hot nipple with constant temperature. stamping automation has no cold material demoulding. the runner and gate are directly on the product, so the runner does not need demoulding. this system is also called waterless system, which can save raw materials and is suitable for the situation of expensive raw materials and high product requirements, and difficult design and processing, the mold cost is higher.
