A, the concept
1, mold: industrial production for injection molding, blow molding, extrusion, die casting or forging molding, smelting, stamping and other methods to get the required products of various molds and tools. In short, the mold is used to make molded items of tools.
2, fixture: refers to the mechanical manufacturing process used to fix the processing object, so that it occupies the correct position to accept the construction or detection of the device.
3, check fixture: industrial production enterprises for the control of various product dimensions (such as aperture, space size, etc.) of the simple tool.
4, jig: is a carpentry, ironwork, clamping, mechanical, electrical control, and some other crafts of a large class of tools.
5, tooling equipment: refers to the manufacturing process used in a variety of tools of the general term.
Two, the difference
There is a difference between these in the application of the object and role.
1, the difference between the object of application
(1) mold for unformed workpiece.
(2) fixture for the molded workpiece.
(3) the checker is applicable to industrial products.
(4) Fixtures are suitable for large workpieces.
Devices used to quickly, easily and safely mount workpieces in any process of the process, such as welding fixtures, inspection fixtures, assembly fixtures, machine tool fixtures and so on.
Which machine tool fixture is the most common, often referred to as fixture, fixture belongs to the tooling.
2, the role of the difference
(1) molds are used to shape the workpiece.
(2) fixture used to fix the position of the workpiece to be detected.
(3) fixture for product inspection.
(4) Fixtures are used for machining large types of workpieces.
The raw material strip is stamped by the mold, and the stamped product strip is then stamped again by the fixture (cut off, partial molding or bending) to get the product that the customer wants.
The checker is suitable for mass production, the checker is more time-saving and labor-saving than the inspection with the general gauge, and the checker also belongs to a kind of tooling.
Extended information:
The molds are widely used in blanking, die forging, cold heading, extrusion, powder metallurgy parts pressing, pressure casting, as well as engineering plastics, rubber, ceramics, and other products of the compression molding or injection molding of the forming process.
Generally includes a moving mold and a fixed mold (or convex and concave mold) two parts, the two can be divided and can be combined. Separate to take out the product, close to make the blank into the mold cavity forming.
The mold is a precision tool, complex shape, bear the blank expansion force, the structural strength, rigidity, surface hardness, surface roughness and machining accuracy have high requirements, the level of development of the mold production level is one of the important symbols of the level of machinery manufacturing.
