Drawings

The present invention will be further explained with reference to the drawings and examples.

Fig. 1 is a schematic structural diagram of the present invention;

fig. 2 is a schematic structural diagram of an embodiment of the present invention;

fig. 3 is a schematic structural view of the slide rail slider of the present invention;

in the figure, the device comprises a base 1, a base 2, a baffle 3, a side plate 4, a compression stud 5, a screw rod 6, a jacking nut 7, a top plate 8, a mould 9, a first cylinder 10, a slide rail 11, a slide block 12, a cushion block 13 and a second cylinder.

Detailed Description

Fig. 1-3 are the structural schematic diagram of the present invention, a die assembly for injection molding machine, which includes a base 1, a mold 8 is placed on the base 1, two sides of the base 1 are side plates 3 perpendicular to the base 1, a hold-down stud 4 is screwed into a screw hole at the top of the side plate 3, and a baffle 2 perpendicular to the base 1 is arranged on the base 1.

When the die assembly for the injection molding machine is used, a mold 8 after injection molding is placed on a base 1, after the width of the bottom edge of the mold 8 is measured in advance, a vertical baffle 2 is welded on the base 1, the baffle 2 surrounds the bottom extension of the mold 8 in a full circle mode to play a limiting role, at least two compression bolts 4 are arranged on the top of a side plate 3 on one side, the lower edges of the compression bolts 4 are located at the upper edge position of the mold 8 through measurement, the upper edge of the mold 8 is slightly higher than the lower edge of the compression bolts 4 in height, so that the end parts of the compression bolts 4 are pressed on the upper edge of a module 8 after the compression bolts 4 are screwed in, due to the fact that the upper part of a top plate 7 is of a rubber pad structure, the mold can slightly press the rubber pad when placed on the top plate 7 to deform the rubber pad, and then the compression bolts 4 are pressed on the upper part of the mold 8, thus, the locking die can be realized.

According to the utility model discloses a further embodiment includes, base 1's bottom welding screw 5, and the cover has a tight nut 6 in top on the screw rod 5, and there is the through-hole at roof 7 middle part, and its through-hole cover is placed on the last edge of tight nut 6 in top after on screw rod 5.

Roof 7 adjusts its oscilaltion through rotating top lock nut 6, after can realizing sinking roof 7 like this, lay the mould, rotate clamp bolt 4 afterwards, make clamp bolt 4 exceed the outer edge of mould 8, the rotation top lock nut 6 of direction again afterwards, top lock nut 6 upwards removes along screw rod 5, and then drive roof 7 shifts up, just so make to lay mould 8 on roof 7 and move up, the upper portion top that makes mould 8 is in clamp bolt 4's lower part, the purpose that compresses tightly whole mould 8 has been played, satisfy the demand of locking.

According to the utility model discloses a further embodiment, further include, there is cylinder one 9 through the bolt fastening in the base 1, and the top of cylinder one 9 is through the bolt fastening has roof 7.
