Abstract

PURPOSE:To permit easy discharging of sand from a blow head by attaching a blow plate consisting of a frame body and an attachable and detachable press contact packing fitted to the frame body into the blow port of the blow head. CONSTITUTION:The operator pulls a press contact packing 8 by hand in the stage of discharging sand from the inside of a blow head 2 and the packing can be easily removed to open largely a blow plate 5. A sand discharging chute 17 is provided via a gas outlet 15 and a partition wall 16 to a gushing head 3. If blow air is blown while the blow plate 5 is brought into press contact with the head 3, the sand remaining in the head 2 is instantaneously discharged from the bottom end of the chute 17.

In mold making machines, especially in cold box molding machines, binders such as phenol resin and polyisocyanate resin are mixed into the molding sand (abbreviated as "super sand"), and the sand is pumped into the mold using air pressure. After blowing, a hardening gas is introduced to form the sand, but if sand remains in the blow head, it will naturally harden and solidify, making cleaning difficult.

For example, in a side blow one-type molding machine using a horizontally split mold, a hole for cleaning is provided on the outside of the blow head, but each time cleaning is performed, the bolts and clamps on the hole cover must be removed and installed, which is a complicated process. Repeated work. Therefore, there is a problem that not only is the work time-consuming, but also that the mounting space, especially in the case of a clamp, is large.

That is, the method for removing sand from a blow head of a molding machine according to the present invention includes installing a blow plate at the blow port of the blow head, which is made up of a frame body that matches the external shape of the blow port and a removable crimp packing fitted into the frame body. After installation and filling with foundry sand, only the crimping packing is removed, and it is crimped onto a sand discharge chute provided on the back of the gassing head, and air is blown into the blow head to discharge the sand. In addition, in order to facilitate the implementation of the method of the present invention, we improved the conventional blow plate, which is made by pasting a packing material around the iron plate.
In other words, the sand removal device of the present invention consists of a blow head main body and a frame body shaped to match the external shape of the blow opening of the main body. , embed the backing material in the groove provided on the outer periphery excluding the bottom part,
It is characterized by consisting of a blow plate in which a crimp packing having holes for blowing sand is fitted into the frame, and a sand discharge chute provided on the back side of the gassing head.

In a cold box core making machine, core sand is filled through the sand inlet of the mold, the blow head is moved back, and the gassing head is instead pressed against the sand inlet to vent curing amine gas. It has become. Although the gashing head itself is suspended around the device and can move freely, it cannot fix its own position. Therefore, in order to carry out the method of the present invention, the gashing head is fixed by pressing the blow plate against the mold. And, since the injection chute of the gassing head is separated from the gas outlet, gas injection and sand discharge can be performed at the same time, independently of each other.
