Abstract

PURPOSE:To cast plural products simultaneously on each cycle operation by arranging the intermediate die individually executing a die matching of both stationary and movable dies by respectively fitting to both faces of the intermediate movable panel which is arranged between the stationary panel and movable panel respectively equipping a knock-out mechanism. CONSTITUTION:When the die closing operation of a machine is started, a movable panel 6 is independently moved in the die closing direction until a movable die 9 is made coincident with relatively opposing intermediate dies 12 with its die matching. After the die matching coincidence an intermediate movable panel 7 is moved with a movable panel 6 to start a die closing operation and an intermediate die 13 is made coincident with a relatively opposing stationary die 8 with its die matching. Then, after die closing by interposing the intermediate movable panel 7 a molten metal is filled in cavities 10, 11 with its injection, and after completion of the curing a product is taken off by starting the machine die opening. Consequently, plural products can be simultaneously cast by each one cycle operation.

Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a horizontal clamp type cold chamber die casting machine, particularly for casting multiple products in which multiple products are simultaneously cast in each cycle of the machine. Regarding machines.

<Conventional technology and its problems> Conventionally, when casting multiple products, for example, two products, at the same time in every 1+1 cycle operation, the parting surfaces of both the fixed and movable molds (which are attached to the fixed platen and the movable platen, respectively) are used. mold parting surface),
The two cavity surfaces connected to the runner (gate 1-) branched from the sprue are formed in parallel with each other facing each other, and the two cavities are 1y by clamping the fixed and movable inner molds.
As a structure in which two sprues are placed in between and arranged in parallel in a direction perpendicular to the mold clamping and mold tapping direction of the machine,
It was common to use a two-cavity process in which two products were cast simultaneously during each cycle of the machine.

However, in this conventional casting method, as the number of products to be cast increases, a large machine with a mold clamping force proportional to the increase is required. In the conventional structure in which cavities are arranged in parallel according to the number of products in a direction perpendicular to the machine's mold clamping and mold opening directions, when the number of products increases, As a result, the cavity area increases by (8) in the orthogonal direction (for example, when casting two products, the cavity area increases by 1).
This is because the area is twice as large as the 17 bite area in the case of individual picking.

Furthermore, in this type of casting industry, it is possible to cast products with complex shapes (multi-scale shapes) by equipping a mold with a large number of drawn cores, each with a different direction. , : With the conventional rust removal method, the direction of removal is more difficult than the direction of removal (the number of pieces) for one product. Since the casting cost is il++1, it is not possible to produce the same product as when casting a single product.There are restrictions on the types of cups that can be produced.

<Technical Problems to be Solved by the Invention> The technical problems to be solved by the present invention are as follows. Provided is a multi-product casting machine capable of casting 2 products, with a 2-cavity casting machine that casts 2 products per recycle operation of the machine, and a U-t'-tll differential area of 2 ( f

<Effects of the Invention> As described above, the machine of the present invention has both fixed and movable dies individually assembled on both sides of the intermediate movable plate arranged between the fixed plate and the movable plate each having an extrusion mechanism. The intermediate molds to be produced are respectively mounted and arranged, and the cavities for manufacturing multiple products, for example, two products, are closed on the machine and configured and arranged individually in the mold direction. During the mold opening operation, the individually arranged cavities can be opened individually to extrude and take out the two cast products. Therefore, if two products are to be cast in each cycle of the machine, even if the cavity area is doubled, the mold closing blade of the machine is smaller than the mold of the machine that casts one product. Closing force is sufficient.

Moreover, since the cavities are configured and arranged individually by combining the movable mold and the intermediate mold, and the intermediate mold and the fixed mold, the drawing core can be removed in the same direction as before. It is possible to cast a product by attaching a drawing core in the same direction as the mold for making one product, without any restrictions on the number of products.

Therefore, although it is a two-piece casting method, products with complex shapes can be produced by casting in the same way as with one-piece casting.

Furthermore, since the molten metal can be injected and filled into the cavity with the same flow direction as when casting a single product, it is possible to fill the molten metal in a better dry flow state than with conventional casting methods, making it possible to cast a single high-quality product. It can be done through production.

Therefore, I achieved the intended purpose and achieved Iq.
