How do the mold maintenance better?

Mould is one of three big essential factors in the production of die casting, die casting mold used good or bad will directly affect the mold life, production efficiency and product quality, relationship with the cost of the die casting. For die casting workshop, mold maintenance and good maintenance are powerful guarantees for normal production runs smoothly, is conducive to the stability of product quality, to a great extent, reduce the production cost of invisible, so as to improve production efficiency. According to the problems encountered in the actual production and plastic mold manufacturer and we discuss how to do the mold maintenance better. First of all: establish archives for mould ready ( 1) Also is to give each a set of mould in the factory set up a complete set of use record, this is to ensure that future maintenance and maintenance of an important basis, each to do meticulous, clear, including production mold times a day. ( 2) As a mould management, mould since the factory, the mold structure of each part of the accessories must be credited to mold archives in detail, and according to the needs, inside the die cut of the wear parts list, are prepared ahead of accessories, such as plunger, core, etc. Vulnerability to set up the minimum inventory spare parts, so as to not delay due to lack of ready to production. Because of such lessons a lot, be prepared to no. If because she wasn't ready to spare parts and delay the production, for die casting enterprise caused by the loss is very big, time, manpower, electricity insulation furnace ( Or liquefied petroleum gas) Is the most main is not small number, such as delays in production, delayed delivery of the goods losses will be bigger! ( 3) To make mould record card at the same time, it is necessary to the permanent mark in the engraved in the mold itself, is easy to distinguish. It won't cause wrong mould farce. ( 4) If with cylinder core pulling of die, deserve to go up as soon as possible to the quick change connectors, otherwise every time disassembling mold from leaking oil in the oil cylinder wasted money enough to pay you several employees one month's salary, you can also use the savings to employees to improve the food. It also greatly shortens the time of die casting operator handling die a few things. Remember to buy some good quality fast joints, or the opposite effect. ( 5) Mould management provisions are formulated in advance, providing people with training system, practical implementation.





how to solve the problem of plastic products (front


if the product appear flash, burr, and front and you said, just name is different, meaning are the same. Is thin plastic edge, the edge of the product appears such a solution is very simple, but there are many reasons for minutes, let me as far as I know the reason for the below.
1, mold temperature is too high. Cylinder temperature is too high, prone to flash. 2, the mold clamping force is insufficient, can also lead to flash. 3, pressure, speed too. Can lead to flash.
4, you said the location is also an aspect, actually the location is very simple, the smaller location, suggests that the more plastic injection molding, is obviously will flash overflow cavity, naturally produced flash. Position from the nozzle of the head is 0, then extended behind, screw, when the loading will be kept back, position also in unceasing increase, such as a product, need 160 mm plastic cylinder position and then begin to go straight from 160, has been to turn you to set the pressure maintaining a turning to the holding process. So, position the value, the greater the flash ( (front) The smaller the will, on the contrary, the smaller the value, flash, (front) The more you will too.
5。 Excessive back pressure and pressure can also lead to flash.
