How to distinguish the inverted mould from other moulds
Inverted compound die is a convex and concave die installed on the lower die base, which is opposite to the formal compound die. According to the different assembly position of the convex and concave die in the die, it can be divided into two kinds: the front mounting compound die and the reverse mounting compound die. Front mounting compound die: the convex and concave die installed on the upper die base is called front mounting compound die. Inverted compound die: the compound die with convex and concave die installed on the lower die base is called inverted compound die.
The inverting die pump is on the ejecting side of the back die thimble, that is to say, the injection and ejecting are on the same side. Various molds and tools are used in industrial production for injection molding, blow molding, extrusion, die casting or forging forming, smelting, stamping and other methods to obtain the required products. In short, a mold is a tool for forming objects. This tool consists of various parts, and different molds consist of different parts.
Mainly through the change of the physical state of the formed material to achieve the processing of the object shape. It is known as the "mother of industry". Under the action of external force, the blank becomes a tool with specific shape and size. It is widely used in stamping, die forging, cold heading, extrusion, P / M parts pressing, pressure casting, as well as the forming and processing of engineering plastics, rubber, ceramics and other products.
Extended data
Large water gate mold: the runner and gate are on the parting line, demoulding together with the product when opening the mold, the design is the simplest, easy to process, and the cost is lower, so many people use large water gate system for operation. Plastic mold structure is divided into two parts: dynamic mold and fixed mold. The movable part of the injection machine is the moving mold, and the inactive part at the injection end of the injection machine is generally called the fixed mold.
Fine nozzle mold: the runner and gate are not on the parting line, generally directly on the product, so a group of nozzle parting lines should be designed, the design is more complex, and the processing is more difficult, generally the fine nozzle system should be selected according to the product requirements. The fixed die part of the fine nozzle die is generally composed of three steel plates, so it is also called "three plate die". The three plate die is the simplest structure in the fine nozzle die.
Hot runner mold: the structure of this kind of mold is basically the same as that of the fine nozzle. The biggest difference is that the runner is located in one or more hot runner plates and hot pump mouths with constant temperature, and there is no cold material demoulding. The runner and gate are directly on the product, so the runner does not need demoulding. This system is also known as the no nozzle system, which can save raw materials, and is applicable to the situation where the raw materials are more expensive and the product requirements are higher, Difficult to design and process.
Mould cost is high. Hot runner system, also known as hot runner system, is mainly composed of hot runner sleeve, hot runner plate and temperature control electric box. Our common hot runner system has two forms: single hot gate and multi hot gate.
Single point hot gate is a kind of plastic mold which uses a single hot gate sleeve to directly inject the molten plastic into the mold cavity. It is suitable for a single cavity and a single gate. Multi point hot gate is a kind of mold which uses a hot gate plate to branch the molten material into each sub hot gate sleeve and then into the mold cavity. It is suitable for single cavity and multi-point feeding or multi cavity mold.
