Description

Detailed Description of the Invention

[0001]

[0002]

2. Description of the Related Art Generally, when maintaining a pair of upper and lower molds, the upper mold is lifted by a wire to divide the upper and lower mold pairs into upper and lower parts.
The upper mold was inverted by 180 degrees. Also, in the mold stored in a pair of left and right, by the wire,
After the pair of right molds were integrally inverted by 90 degrees, the upper mold was lifted by a wire and inverted by 180 degrees in the same manner as above. However, in order to lift and reverse the mold by 90 degrees or 180 degrees, at least two cranes or a large crane having a main winding and an auxiliary winding are required, resulting in high equipment cost and working space. Has occurred. Furthermore, lifting the upper mold with a wire and reversing it will increase the time required for reversing and avoid damaging the mold in the process of reassembling the upper 7 mold with the lower mold. Since high precision is required, the work efficiency is significantly reduced.

Therefore, a mold dividing and reversing machine for vertically dividing a pair of upper and lower molds and reversing the upper mold by 180 degrees has been put into practical use. This mold split reversing machine has 1
There are a reversing table supported by a pair of supporting members through a shaft member so as to be reversible by 180 degrees, a rotary driving device that rotationally drives the shaft member to reverse the reversing table, and a lifting drive device that drives the reversing table up and down. The pair of upper and lower molds provided is placed on a slide table and conveyed to the lower side of the reversing table, and then the upper mold is fixed to the lower surface of the reversing table driven to descend by an elevating driver. The reversing table is lifted to divide the pair of upper and lower molds into upper and lower parts, and the upper mold is moved to the upper mold together with the reversing table through the shaft member by the rotary drive machine.
Inverted by 80 degrees.

[0004]

However, in the above-mentioned mold split reversing device, since the shaft member of the reversing table is driven to reverse the reversing table by 180 degrees, the reversing table is rotated. A large driving torque is required. That is, since it is necessary to mount an expensive rotary driving machine that generates a high output, the manufacturing cost of the mold division reversing device becomes very expensive. Further, in this mold split reversing device, only a pair of upper and lower molds is vertically divided, and the upper mold is reversed by 180 degrees. In case of mold,
First, since it is necessary to invert a pair of left and right molds by 90 degrees using a device other than the mold division reversing device, there arises a problem that work efficiency is significantly reduced. The object of the present invention is to simplify the supporting mechanism and the rotation driving mechanism for rotation driving, downsize the rotation driving mechanism, apply to a pair of left and right molds, and can be manufactured at low cost. Is to provide.

The upper mold fixed to the plate is turned over 180 degrees.

In the case of a pair of left and right molds for a horizontal injection molding machine, the rotary drum is inverted 90 degrees from the initial position and the upper fixing plate is set at a position where the left mold can be fixed. After that, in order to fix the left die to the upper fixing plate, the elevating and lowering means raises the elevating table to a predetermined height as necessary, and the left die is fixed to the upper fixing plate. Next, when the elevating table is driven downward, the rotating drum rotates the rotating drum 90 degrees to the initial position, and then the elevating table is driven upward until it comes into contact with the lower die, and the upper die is moved. The connection between the mold and the lower mold is released, and the lower mold is placed and supported on the lift table. Next, the lower mold is lowered together with the lifting table by the lifting drive means, and then the rotary drum is rotated by the rotation drive means to the reversal position rotated by about 180 degrees from the initial position, and the upper fixing plate is moved. The upper mold, which is fixed to, is turned over 180 degrees.

After fixing the upper mold to the upper fixing plate, the connection between the upper mold and the lower mold is released. Next, by the lifting drive means,
After the upper fixing plate is driven up to a predetermined height together with the upper die, the die loading / unloading carriage is moved to the outside of the rotary drum. Next, the rotary driving means rotationally drives the rotary drum to the reverse position which is rotated about 180 degrees from the initial position. Then, the mold loading / unloading carriage is moved into the rotating drum again so that the inverted upper mold can be placed on the lifting frame, and if necessary, the upper fixing plate is driven downward and inverted. The upper mold is transferred from the upper fixing plate to the lifting frame.

According to this die split reversing device,
Although it is possible to obtain substantially the same actions and effects as the die split reversing device of No. 0, since the rotating drum is provided with the elevating and lowering drive means for vertically moving the upper fixed plate, it is possible to elevate and lower the underframe of the die loading / unloading carriage.
