Toy mould processing, tell the reason of the mould unit and loss
A toy mold processing - mold unit:
Mold alignment unit, also known as a pair of die cutting edge of the boot device. In order to maintain the alignment of the upper die and the lower die and shorten the preparation time, according to the requirement of the product precision and the production quantity, the mold alignment unit mainly has the following five kinds of:
(1) no guide type: the mold is installed in the punch press directly when the blade of the work, not to use the boot device.
(2) outside guidance type: this device is the most standard structure, the guide device is installed on the upper die and the lower die seat, not through the various templates, generally known as die seat type.
(3) the external guidance and guidance and type (a): this device is the structure of progressive die are most commonly used, the punch fixing plate and pressure plate arranged is arranged in the guide device. The use of fixed pin and the guiding device of the punch and die. The guide device inside another role is to prevent the pressure plate to tilt and protect small punch.
(4) the external guidance and guidance and type (2): this device is a high precision high-speed progressive die structure and guiding device through the punch fixed plate, a pressure plate and the concave die fixing plate, and so on. In the guiding device itself has the edge parts of mold and protect small punch. The main function of the external guiding device is to be able to obtain the smooth purpose when the mould is decomposed and installed on the punch press.
(5): Guidance: this structure does not use external guiding device and guiding device punch fixing plate, pressure plate and the concave die fixing plate through and so on and properly maintain the position relationship between the sheets to protect the punch.
Two, toy mold processing - the cause of the loss of mold:
1) the main parts of the mold material problems, improper selection of material. Material performance is bad, do not wear; die steel not refined, with a large number of smelting defects; convex and concave die, forging instead of forging process is not perfect, the remains of a heat treatment risks.
2) the mold structure design problem, the die structure is not reasonable. There is no design and reinforcement device for the long and thin convex mould, the discharge port is not free, and the discharge capacity of the material is over.
3) molding process is not perfect, mainly in the convex, concave die forging billet internal quality is poor, heat treatment technology and process problems, resulting in convex, concave mold quenching, there are soft points and hardness. Sometimes produce micro cracks, or even crack, grinding and polishing is not in place, the value of surface roughness is too large.
4) no lubrication or lubrication but the effect is not good.
