At present, when foam manufacturers produce foam boxes, they generally use molds to make them. Because the molds need to be continuously repeated, cycle heating, cooling, reheating, and cooling during use, in order to reduce consumption and increase molding speed, The material selected for the mold must be easy to transfer heat, so copper and aluminum are the first choice, and because the copper material is relatively heavy and the cost is high, the traditional foam mold is generally cast in raw aluminum, but the raw aluminum mold has a higher tensile strength. Low, easy to break, not easy to repair after breaking, short service life and other disadvantages, if a certain part is damaged, the whole set of molds will be scrapped, which not only delays production, but also increases the cost of mold production, but if the mature aluminum material is replaced, the mold will be damaged again. easily transformed.
The problem to be solved by the utility model is to provide a foam box mold which reduces production cost, prolongs service life, facilitates maintenance and improves production efficiency.
In order to achieve the above object, the technical solution adopted by the utility model is-
A foam box mould, comprising a cast steel punch outer frame and a cast steel die outer frame, characterized in that the outer side of the punch outer frame is provided with a cast steel punch outer panel, and the inner side is provided with a cast steel punch inner panel. The inner panel of the punch is provided with several inner cores of the cast aluminum punch, and a sealed punch chamber is formed between the inner core of the punch, the inner panel of the punch, the outer panel of the punch, and the outer frame of the punch. ;
The outer side of the outer frame of the die is provided with a cast steel die outer panel, and the inner side is provided with a cast steel die inner panel, and the die inner panel is provided with several cast aluminum die inner cores, and the die inner core and A sealed cavity is formed between the inner panel of the concave mold, the outer panel of the concave mold and the outer frame of the concave mold, and the inner core of the concave mold cooperates with the inner core of the male mold to form a mold cavity.
The following is the further improvement of the utility model to the above-mentioned technical solution
A punch jack is provided between the punch inner panel and the punch outer panel, and a die jack is provided between the die outer panel and the die inner panel. Beneficial effect
The utility model adopts the above-mentioned technical scheme to separately manufacture the inner core of the punch, the outer frame of the punch, the outer panel of the punch, the inner panel of the punch, the inner core of the die, the outer frame of the die, the outer panel of the die, and the inner panel of the die. , processed separately, so that no matter which part is damaged, it can be replaced or repaired independently, which greatly saves the cost of mold production. The inner core of the punch and the inner core of the die are made of cast aluminum, which is conducive to internal heat transfer. The panel and the outer panel of the concave mold are made of cast steel. Because of the slow heat transfer of cast steel, it is not easy to leak the internal heat, which not only saves energy, but also prevents the mold frame from cracking. Even if it is damaged, it can be easily welded and repaired. , the utility model not only reduces the production cost, but also reduces the mold manufacturing cost, can replace the mold quickly, ensures the normal operation of the production, and improves the production efficiency.
