Q:What do you do with the exhaust? How are we going to

There are many ways to exhaust the cavity, but every method must be guaranteed: the exhaust groove should be designed to prevent the material from spilling into the slot. The second is to prevent blockage. Therefore, from the surface of the cavity of the cavity to the cavity of the cavity in the cavity of the cavity, the exhaust tank of 6 to 12mm long, the slot height should be about 0.25 to 0.4 mm. In addition, the number of exhaust slots is harmful. It is dangerous to cause cold flow or fissure in the cavity material if the mode of the lock mode is very high in the part of the cavity that is not open. In addition to outside the parting surface of cavity exhaust, also can be in the end of the pouring system of material flow set exhaust slot location, and leave gaps around the ejector rod achieve the goal of exhaust. Because of the depth, width, and location of the exhaust groove; If not properly, the resulting spines will affect the aesthetics and accuracy of the products. Therefore, the size of the above clearance is to prevent the appearance of the flying side near the top of the rod. It should be noted that in the exhaust of the gear such as gears, it may not be possible to have even the smallest edge. This type of assembly is best to exhaust the air in the following way. The size of 200 # carbide abrasive is applied to the surface of the parting surface. In addition, in the end of the pouring system of material flow to open exhaust slot is mainly refers to the position at the end of the shunt way exhaust slot, its width should be equal to the width of the distributary channel, height varies depending on the material.

Q:What is the relation between the mould and the clamp

The mould is made directly by its shape (including pressing, die-casting, injection molding, stamping, bending, extrusion, etc.). Such as powder metallurgy mould, hardware mould, plastic mould etc. A fixture is an auxiliary tool, usually a tool used to fix a processed object or process tool. Like pressure board, drill clip first class.

Q:What is the cooling system of the mold

Exactly, the thermostat system of the mold should be called. Cooling, it's just part of this constant temperature, and the other part is insulation. In the process of injection molding, according to the material, the requirements for the mould temperature are different. For example, PP material, the temperature requirement of the mold is not high, the circulating water cooling is ok, it is ok to keep room temperature. But some materials, such as PC, require that the temperature of the die need to be kept above 80 degrees, which requires the temperature of the temperature machine to warm up the water. There are some special materials such as PPS (PPS) to demand a higher mold temperature above 150 degrees, also need the oil temperature machine or electric heating rod to heat the mold. Thermostatic system generally is in the mold cavities internal hole, forming one or more than one closed loop pipes, hoses, a into a mission of water flow in the pipeline, to keep the temperature of the mold temperature is constant. This is the die water. The other is the heating rod, which is inserted into the molds of the molds to keep the temperature above 100 degrees. It should be said that most of the moulds should be made by water, and no water will affect the life of the mold, mainly by the effect of injection molding process.

Q:Introduction to mould design and manufacturing

Develop mold design and manufacturing of advanced applied technology talents, graduates can be engaged in the enterprise production fixtures and tools needed for the design and manufacturing, mold assembly and debugging, mold enterprise operation and management. Main course: mechanical drawing, mechanical design and foundation, cold stamping die design and manufacture, design and manufacture of injection moulds, and the programming of numerical control technology, mould processing machinery, electrician and electronic technology, hydraulic and pneumatic transmission, metal cutting principle, mechanical CAD/CAM, etc. One, cultivate goals This professional training support the party's basic line, to adapt to the production, construction, management and service first line need, moral, intellectual, physical, beauty and other aspects of comprehensive development, mold design and manufacturing of the basic theory and knowledge, engaged in mold design and processing, manufacturing, and maintenance of advanced technology applied talents.

Q:What is the "KO hole" on the injection mold?

KO hole, also called the top roller, is to do in the mold after the mold on the front panel, in order to make injection molding machine ejection, top stick can directly to the plunger on a board, and dig holes on the panel to avoid empty. The location of the KO hole is on the same axis as the spout. Sometimes according to the actual situation of the mold to open several KO hole, then according to the dynamic injection molding machine template parameters to determine the location of the KO hole, other is already open on because of the injection molding machine template for porous as caving sticks.

Q:How many kinds of equipment can be used to open the mould?

Its success or failure depends largely on the design. General tooling development requires common processing equipment, heat treatment equipment, to accommodate the special and uniqueness of the development parts. Nc machine tool, the processing center is also the good practitioner of the open mode; In recent years, special processing equipment, such as electrical erosion, laser, ultrasonic, etc. Are also gradually entering the mould processing area.

Q:How to choose the injection molding machine when the mould design

If you choose me as a manufacturer of injection molding machines, we will do our best to help you design the equipment you want

Q:What is the role of the grooves in the guide column

We usually call it "tank." You can touch the butter in it! At the time of the mould, touch the butter, lubricate and extend the life of the guide column.

Q:Is the stamping tool to be used for the precision of the stamping parts? Why is that?

As for accuracy, for example, a round piece, 10mm in diameter, iron material with a thickness of 1.0. Because is the materials for the product, so the size of the circle is determined by the size of the lower die inner hole, lower die blade diameter of 10.00 mm, according to the calculation of blade gap, unilateral clearance should be 1.0 * 0.05 = 0.05 mm, so the punch diameter is 9.90 mm. And you said that the precision of the pledge is also need precision mold parts, then see how the parts are processed, such as wire cutting, fast wire cutting and slow wire cutting, the precision of plus or minus 0.02 mm, the latter is plus or minus 0.002 mm. The difference is 10 times, the part accuracy that makes is of course different, the size of the product that is processed, the size of the margin of the hair side is different also.

Q:The role of the die positioning ring

The positioning ring is a metal ring used in the system of die heat flow. It is characterized by high temperature and high precision. There are two types of type A and B, and there are different models for special needs. In addition to locating the sprue, the positioning circle can also be used for fasteners, which can be used as a fixture.
