2. Main Features of Multi-Cavities PP Preform Mould 

Mouse mould design is a brain demanding work which has no copy action.

When designing a mouse mould the method of modification should be taken into consideration  and should have enough space for modification.

The devices of the mouse mould should meet the standard of anti-grating and long-life shots.

The manufacturing skill and time are different with the hardness and stretchiness of the material.

Because of its precision, most of work has to be done by manual work.

Mould of high quality should be qualified with good surface manufacturing and precision

Q:What is the use of the mold collecting water
Gather the water seat, and set the point cold to one.What does the water block mean? Listen to the transition block, don't know if you're talking about it?.
Q:The performance requirement of die steel
Compressive yield strength and compressive strength of bending strength mould in use process is often high pressure and bending effect, so the mold material should have certain compressive strength and bending strength. In many cases, the compression test and bending test conditions close to the actual working conditions of mould (for example, measured by the steel compressive yield strength and deformation resistance of punch work was coincident). Another advantage of the bending test is the absolute value of the dependent variable is large, can be more sensitive to reflect the different steel grade and condition in different heat treatment and organizations between the difference of deformation resistance.
Q:Where is the mould industry in our country?
Shanghai Shanghai has more than 1, 500 molds enterprises, with more than 70,000 employees and annual output of nearly 10 billion yuan, with an average annual growth rate of more than 20 percent. By 2010 the total output will be around 20 billion yuan. Imports from the current 290 million yuan based on compressed 30%, will increase 700 million yuan output value of industry, exports reached $130 million, and will increase 600 million yuan output value of industry. Shanghai mold industry will face six major industries and key industries, especially the information (IT) industry and automobile industry, vigorously develop the IT industry precision magnesium alloy die casting, precision injection mold; The auto industry covers molds, large parts die-casting molds and precision stamping parts. In 2010, 85 percent of the molds in the IT industry were manufactured and 90 percent of the auto molds were produced.
Q:What is the difference between mould injection and blow molding?
Generally speaking, the injection molding is the solid core, blow molding is the core body, the blow molding surface is uneven. Blow molding has the air port. Injection molding, or thermoplastic plastic injection molding, is the process of melting the plastic material and injecting it into the membrane cavity. Once molten plastic enters the mold, it is cooled and molded into a shape. The resulting form is often the final product, which is no longer needed before the installation or final product is used. Many of the details, such as the bulge, rib and thread, can be formed in the injection molding process. The injection molding machine has two basic parts: the injection device and the coder that melt and feed the plastic into the mould. The function of the die device is: 1. Remove the product from the injection device before it is injected into the mold and melt it, then control the pressure and speed to inject the melt into the mold. The current injection device has two designs: a screw preplasticizer or a two-stage device, and a reciprocating screw. The screw type preplasticizer USES pre-plasticized screw (first class) to inject the molten plastic injection rod (second level). Screw pre plasticizing unit is constant, the melt quality the advantages of high pressure and high speed, and precise injection volume control (using mechanical thrust device) at the ends of the piston stroke
Q:How do you play the continuous stretch mold
More than 3 Zhang Chengpin photos Now want to know how he made, and calculate methods and specific steps, he is the one step forming or stretch forming step by step.
Q:What is the mold for?
As mentioned before, the plastic forming theory and mathematics modeling is not perfect, caused by stamping process analysis and formulation in the design phase is not perfect, need bench late a large number of debugging, this problem may be irremediable solution for, still can reason to evade a responsibility appropriately for designers, but the mechanical structure of the mould level is not good, for the kind of "line", as if we would be a little difficult to quit the effect, of course, I think it's also have many causes. First of all, the more high-end mold mechanical structure generally applied in complex parts and processes, such as car side plate, wing plates, engine hood pressing parts, such as domestic auto manufacturers due to many reasons such as sino-foreign joint venture, it is difficult to make the domestic mold enterprise manufacturing this kind of product of mold, new models of similar parts is often deprived, so we seldom opportunities for actual combat, some powerful manufacturers can be less in production tasks, practice habits conducted theoretical design, heaven knows earth knows the final effect is people do not know!
Q:What is a mold, and what is a mold
Mould industry in China is only about 50 years, mould simple said is the mother of industry, economic benefit, is the amplifier from daily necessities to the aerospace, transportation, electronics, transportation and other industries of national economy is inseparable from the mould, in short, we have encountered heard 90% of all kinds of items are mold production and processing. The mould includes various kinds, such as plastic mould, stamping die, hardware mould, powder metallurgy, casting and so on. The concept of a mold is relatively general, but there must be a few aspects, 1, 2 independent process molding function, complete the process of molding process 3, finished parts removed. This is an essential aspect.
Q:What does it mean to have a rough die
The tool is used to process the rough shape of the mould. And the machine tool and cutter that open coarse use is less accurate, such processing speed is relatively quick. It needs to be left with a residual amount, and then replaced with a processed machine tool and tool. Die strategy: Follow the perimeter: less knife, more clean blade, more empty blade, suitable for electrode processing, avoiding the phenomenon of the cutting of the knife in electrode processing. Follow the workpiece: it is not easy to cut, the way is safe, it is suitable for steel material processing, lifting the knife.
Q:Would you please tell me what the difference in the mold Tooling and mold
Please say on the injection molding product is marked: 5200 is the mold material is 5200 or what?
Q:The core is the moving or the model, male or female?
Dynamic model is also called the male die, die is also called the master pattern, as far as the core is a dynamic model with fixed mode is not necessarily, just general design core in moving die, it is because we hope that after mold opening mold, plastic pieces on a dynamic model of ejection device, so the general core in moving die.
