Description

[Detailed explanation of the invention] This invention has a combination core to be set in the main mold.
This invention relates to a core assembly device that automatically assembles cores during the transport process up to the main mold.

In general, molds for cylinder blocks such as engines are made by assembling water canals and other cores onto the cores of the cylinders, which are each transported by a conveyor, and placing this combined core in a separately molded main mold. However, it requires a lot of time and effort to assemble each core, and has the drawback that it is easily damaged during handling.

The present invention was developed in view of these drawbacks, and a temporary holder is provided on the core storage pallets that are placed at appropriate intervals on the conveyor and are transferred one after another, and the cores are placed on this temporary holder by a machine or a machine. By manually placing the core storage pallets overlappingly on the core assembly table, each core can be moved from the temporary holder of the core storage pallet to the fixing tool and slider of the core assembly table. It is an object of the present invention to provide a core assembling device which can be received and supported by a moving tool and can be assembled by the sliding action of a sliding tool to automate and save labor in the core assembling work.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of the present invention will be described in detail below with reference to the drawings.

As shown in FIGS. 1 to 7, 1 is a core assembly device. The core assembly device includes a core assembly table 2
, a core-accommodating pallet 3 , and a conveyor 4 for conveying and placing the core-accommodating pallet onto the core assembly table 2 . 5 is a main mold placed on a base 6; 7 is a combination core 10 placed on a core chuck 7;
a is a core setter that holds the cores and transfers and sets them into the main mold 5; 8 is a conveyor that transports the core storage pallet 3 through a progressive line 8a and a return line 8b;
9 is a pallet holder, and 10 is a combination core formed by assembling a cylinder core 11 and a water sleeve core 12.

On both sides (only one side is shown) of the core assembly stand 2, there are fixed fixtures erected on a floor plate 21 to support the cylinder core 11 at a fixed position (A in FIG. 7). The tools 22 and 23 support the water cannula core 12 to be assembled into the cylinder core 11, and move the water cannula core from the assembly preparation position (B in FIG. 7) to the assembly completion position ( In order to move it to C) in FIG. 7, it is provided with sliding tools 25 and 26 that protrude above the floor plate 21 and can be slid in the horizontal direction by a driving means 24 such as a cylinder. 27 is a sliding tool 25,
An assembly table opening 26 is formed in the floor plate 21 with a sliding range length, and 28 is a positioning pin that engages with a positioning hole 38 of a core storage pallet 3, which will be described later.

The core storage pallet 3 stores many types of cores (cylinders) in an arrangement state corresponding to the regular position A and the assembly preparation position B of the core assembly table 2 on both sides (only one side is shown) in FIG. Temporary fixtures 32, 33, 34, 35 erected on the bottom 31, fixings 22, 23 of the core assembly base 2, and sliding Moving equipment 2
openings 36a, 36b, 37a, 37 formed in the bottom 31 through which the sliders 25, 26 pass and enable the sliding ranges of the sliders 25, 26 to be slidable;
It is equipped with b. Reference numeral 38 denotes a positioning hole drilled in the pallet flange portion 39 for engaging with the positioning pin 28 of the core assembly table 2 when stacking the core accommodation pallets 3 from above the core assembly table 2. be.

The conveyor 4 is equipped with a pallet chuck 41 at its lower end, lifts the core storage pallet 3 from the pallet holder 9, conveys it above the core assembly table 2, and fixes the core assembly table. The tools 22, 23 and the sliding tools 24, 25 pass through the openings 36a, 36b, 37a, 37b of the core storage pallet 3 and move the cores 11, 12 in the core storage pallet 3 to the temporary holder 3.
2, 33, 34, and 35 to push down the core storage pallet 3 until it is placed at a predetermined position D where it is received and supported.

In the above structure, first, the core storage pallets 3, 3, . The cylinder part core 11 is placed on the temporary holders 32 and 33 of the core storage pallet 3 being transferred, and the water jacket core 12 is placed on the temporary holders 34 and 35.
Place each one manually.

Next, the core-accommodating pallet 3 that has reached the pallet holder 9 at the end of the progressive line 8a is held and lifted by the pallet chuck 41 of the conveyor 4, and is conveyed forward (to the left in Fig. 1) to the middle. It is stopped at a position above the child assembly table 2, and the core storage pallet 3 is lowered by the conveyor 4 and positioned by the engagement of the positioning hole 38 and the positioning pin 28, and each of the cores 11, 12 is Fixtures 22, 2 for core assembly stand 2
3 and sliding tools 25 and 26, the conveyor 4 is returned to the position above the pallet holder 9. Next, the driving means 2 of the core assembly stand 2
After assembling the water sleeve core 12 to the cylinder core 11 by driving the sliders 25 and 26, the combined core 10 is held by the core chuck 7a of the core setter 7. It is lifted up, transported forward (to the left in FIG. 1), lowered at a position above the main mold 5, and transferred and set on the main mold 5. Further, the empty pallet on the core assembly stand 2 is returned to the pallet holder 9 by the conveyor 4 and then transferred to the return line 8b.

The cores 11, 12 of the following core housing pallets 3, 3, .

In the present invention, with the above-described structure, the temporary holding tool for the core storage pallet and the fixing tool and sliding tool for the core assembly table are arranged at positions where they do not interfere with each other, and the core storage pallet has An opening is provided through which the fixing tool and the sliding tool of the child assembly table can pass and the sliding range of the sliding tool is slidable, and the core-accommodating pallet is moved into the core assembly by a conveyor. Since they are placed one on top of the other on a mounting table, automatic mold painting is possible by automating the core delivery and core assembly work, eliminating core damage caused by manual work and significantly improving workability and productivity. It has the excellent effect of improving
