果も有している。2. Description of the Related Art As shown in FIG. 1, a conventional method of casting a lattice body is to dispose a movable die 3 on a post 2 of a fixed die 1 and then pour molten lead 5 into a pouring section 4 to form a grid. The grid body was manufactured by spreading over the space in the mold and solidifying by cooling. FIG. 2 shows the contact surface between the fixed mold 1 and the movable mold 3,
A powdery cork 6 is sprayed on the surfaces of both to bring the cork layers into contact with each other. The cork 6 has a heat insulating effect and also has an effect of discharging air inside the mold to the outside at the time of pouring molten lead by utilizing its porosity. Here, the space portion 7 is a portion in which the lead alloy enters after pouring and solidifies by cooling to form a part of the lattice. Further, the cork 6 also has the effect of improving the separation from the mold after cooling and solidifying the lead alloy.

ていた。Problems to be Solved by the Invention However, recently, there is a tendency to require light, thin, small, high precision and high quality, and the method using a cork heat insulating layer as described above is insufficient in accuracy, quality and productivity. In the above-described method, an increase in the number of products causes thermal deterioration of cork, resulting in a decrease in the thickness accuracy of the lattice body, leading to instability of product performance. Further, the productivity is deteriorated by increasing the thickness of cork withdrawal, and the casting of a thin and fine lattice body has a drawback that the molten metal runs poorly.

型を示すものである。Means for Solving the Problems The present invention solves the above-mentioned drawbacks, and achieves the air replacement, which was the role of the cork, with a fitting jig incorporated in a mold, and allows air to pass through necessary parts. However, by providing a gap that does not allow molten lead to enter,
The replacement of molten lead with air is improved. That is, a concave portion is provided in either the fixed type or the movable type, and a jig having a projection is partially fitted into the concave portion, so that the molten lead alloy cannot enter the concave portion by the projection of the jig. A narrow gap is provided, and this gap represents the grid-type mold for a lead-acid battery that is in communication with the outside outside the mold.
作用 このような鉛蓄電池用格子体鋳型を採用することで、
コルクの３つの役割の１つである空気置換の作用を軽減

ク粉末の剥離も少なくなる。Action By adopting such a grid body mold for lead-acid batteries,
The effect of air displacement, which is one of the three functions of cork, can be reduced, and the amount of cork sprayed can be reduced.
In other words, the heat insulation effect is reduced, the poured lead alloy solidifies quickly, the mold rotation cycle for grid production is improved, and there is no need to increase the pressure at the time of pouring.

ある。An embodiment of the present invention will be described below with reference to the drawings. FIG. 3 shows a sectional structure of the movable mold 3 according to the present invention. The movable mold 3 is provided with a concave portion 8 in a part of a mold. Even if the recess 8 is provided in the fixed mold 1, there is no problem in practice.
Since the recess 8 is a portion forming an air replacement groove at the time of pouring, the recess 8 is arranged near the lattice bone or including the lattice bone, and is provided so as to be open to the atmosphere outside the mold. The depth of this groove is preferably about 10 mm, but since it is affected by the size of the mold, it can be arbitrarily set to an amount necessary for air replacement. A fitting jig 9 partly reduced by 0.05 mm on one side and 0.1 mm in overall width is fitted into the recess 8. This fitting jig 9
Is formed so that the width of the space inside the movable mold 3 becomes narrower.
It can be formed as shown in the figure. However, since the fitting jig 9 smaller than that of the concave portion 8 is located in the entire width, there is a gap 11 between the two as shown in FIG. 5, and this portion becomes clogged when the cork 6 is sprayed. Air replacement cannot be performed. Therefore, if the cork 6 is blown while blowing air at a pressure of 2 kg / cm 2 in the opposite direction from the gap 11, clogging of this portion can be prevented. FIG. 4 shows a state in which the cork 6 is sprayed on the surface of the movable jig 9 after the fitting jig 9 is inserted into the movable mold 3. FIG. 5 is an enlarged view of a portion A in FIG. 4, and shows a state at the time of end of cork spraying between the movable mold 3 and the fitting jig 9.

換用空間10を通り、大気中に排気されることになる。In this gap 11 of 0.05 mm, the poured lead alloy cannot enter into the molten state due to its surface tension in the molten state. In order to keep the gap 11 at a constant interval, a projection 12 is partially provided on the fitting jig 9 as shown in FIG. 6, and this serves to determine the position in the concave portion 8 in the movable mold 3. . After the above configuration, the molten lead 5 is poured into the pouring section 4, and as the hot water flows into the space 7 forming the bones of the lattice in the mold, the air in that portion is removed from the gap 11 for air replacement. The air passes through the space 10 and is exhausted into the atmosphere.

果がある。Effect of the Invention The air displacement in the mold according to the present invention prevents the deterioration of cork, reduces the amount of spraying to half of the conventional amount, improves the accuracy of the lattice thickness, stabilizes the product performance, and reduces the cooling time, thereby improving productivity. There is a remarkable effect such as improvement of work and improvement of work environment.
