Technical Field [0001] The present invention relates to a mold base for a mold manufacturing apparatus,

The present invention relates to a mold support for a mold manufacturing apparatus, and more particularly, to a mold support for a mold manufacturing apparatus, and more particularly, to a mold supporting apparatus for a mold manufacturing apparatus, which is capable of selectively mounting one or a plurality of molds used in a continuous automation apparatus of a sand mold It is possible to improve the production efficiency by greatly reducing the production efficiency and to make the sand mold (sand mold) robust by allowing the vibration to be selectively transmitted to the inside of the sand mold (sand mold) The present invention relates to a mold support for a sand mold manufacturing apparatus.

Molds commonly used for casting include sand molds that are made by molding sand casting solidly, molds that are made by engraving metal such as steel, Shell molds are used in which a mixture of sand and hardened synthetic resin particles is sanded on a pre-heated metal mold to solidify the mold to form a thin shell-like mold.

In particular, in the case of sand molds using casting sand, it is necessary to make as much as the number of castings required for production, since breakage is inevitable if the casting is poured out after pouring molten metal, It is a matter of course that mass production is necessary in accordance with the required quantity of the casting.

However, the conventional facilities proposed for the mass production of dead bodies have only very complex structures, which only increase the cost of manufacturing and facilities construction, and the operation and operation system is extremely passive and ineffective There is a problem that it requires a lot of work hours and labor. Especially, the problem that the safety accident of the worker can occur at any time due to the poor working environment caused by the scattered dust is left unattended everywhere, There is a limit to the increase and the competitiveness of the enterprise, and a new alternative is required.

Accordingly, the applicant of the present application filed a patent application (No. 10-2012-0130784) on Nov. 19, 2012 for a continuous automated manufacturing apparatus and a manufacturing method of sand molds, in which a sand mold is produced by a continuous automatic apparatus, I received a patent registration in February (No. 10-1232759).

As shown in FIG. 1, the serpentine continuous automatic manufacturing apparatus S is a linear or 'a' type mold for continuously and repeatedly entering and discharging the mold frame 1, which is composed of a pair of upper and lower pairs, A plurality of foreign objects attached to the bottom of the lower mold die between the upper and lower sets of die die 1 transferred from the transfer unit 100, A foreign matter removing unit 400 for removing the various foreign substances including the molding sand attached to the upper surface of the lower chamber 550 in which the sand mold frame 1 is seated and positioned, A holding part 500 for holding the sand molds so that the upper sand mold 2 and the lower sand mold 3 in the sand mold 1 are separated from each other and the separated sand mold can be maintained, And the molding sand filled in the casting mold (1) A casting mold supplying part 700 for sequentially supplying the foundry sand to the lower casting mold 3 and the upper casting mold 2 and a casting mold 1 supplied with the foundry sand, A vibration generating unit 800 having a vibrating element 810 operated by pneumatic pressure and a mold 910 for manufacturing a sand mold so as to maintain a firm fixed state by cohesive force without applying any vibration to the foundry sand, And a mold supply unit 900 for supplying the mold by repeating forward and backward movement between the upper mold die 2 and the lower mold die 3.

[

However, the mold 910 and the vibration element 810 for generating vibration are mounted and fixed integrally with the mold on the upper side of the mold. When a product is to be produced using another mold, the vibration element 810 mounted on the mold Since it was necessary to disassemble and then mount it on a new mold, it took a lot of time to disassemble and install it, which resulted in a decrease in productivity.

In addition, there is a problem that the inside of the sand mold is not formed into a solid shape due to the vibration transmitted by the vibration element, and a phenomenon of breaking down occurs. In manufacturing a sand mold having a small size, , It was not possible to produce sand molds efficiently.

Accordingly, the present invention has been made in order to solve the above-mentioned problems, and it is possible to improve the productivity by allowing two sand molds to be formed simultaneously in one molding, A mold support for a sand mold-making apparatus is provided that not only can a time required for replacing a mold be greatly reduced, but also a time when a vibration is generated is generated at a predetermined interval so that a solid sand mold can be formed The present invention has been made in view of the above problems.
