Description

Technical Field

[0001] This utility model relates to the field of jigs for manufacturing, specifically a jig for manufacturing injection molding machine mold head plates that is easy to use. Background Technology

[0002] Injection molding machines, also known as injection molding machines or injection machines, are the main molding equipment used to make various shapes of plastic products from thermoplastic or thermosetting plastics using plastic molds. The injection molding machine's clamping head plate, usually called the clamping unit or clamping head, is one of the key components of the injection molding machine. It plays a role in fixing the mold during the injection process, ensuring that the plastic does not leak out of the closed area of ​​the mold during injection. The injection molding machine heats the plastic and applies high pressure to the molten plastic, causing it to be injected and fill the mold cavity. The mold of the injection molding machine needs to be fixed by clamps.

[0003] Most of the convenient injection molding machine mold clamping head plate preparation fixtures on the market use hydraulic pumps to fix the mold. This fixing method is relatively inconvenient to operate. After long-term use, hydraulic pumps often experience oil leakage and oil shortage, which causes inconvenience to related work. In addition, the mold clamps used for injection molding machines generally clamp tightly and with great force, which can cause squeezing damage to the mold. Utility Model Content

[0008] Furthermore, the fixed box has a movable hole, through which the sleeve passes through the fixed box.

[0009] Furthermore, the electric telescopic rod includes a forward electric telescopic rod and a lateral electric telescopic rod, the forward electric telescopic rod being hinged to the upper end of the limiting plate, and the lateral electric telescopic rod being hinged to the side of the limiting plate.

[0010] The number of lateral electric telescopic poles is two.

[0011] Furthermore, the output end of the forward electric telescopic rod faces the side of the vertical clamping block, and the output end of the lateral electric telescopic rod faces the side of the transverse clamping block.

[0012] Furthermore, the output end of the forward electric telescopic rod is hinged to the vertical clamping block, and the output end of the lateral electric telescopic rod is hinged to the transverse clamping block.

The limiting plate 9 is fixedly connected to the side of the sleeve 6. The horizontal clamping block 7 and the vertical clamping block 11 are both hinged to the sleeve 6. The electric telescopic rod 10 is hinged to the limiting plate 9.

[0027] In this embodiment, the sleeve 6 has a threaded groove inside, and the sleeve 6 is threadedly connected to the outside of the bidirectional threaded rod 5 through the threaded groove.

[0028] In this embodiment, the fixed box 3 has a movable hole 8, and the sleeve 6 passes through the fixed box 3 through the movable hole 8.

[0031] In this embodiment, the output end of the forward electric telescopic rod faces the side towards the vertical clamping block 11, and the output end of the lateral electric telescopic rod faces the side towards the horizontal clamping block 7.

[0032] In this embodiment, the output end of the forward electric telescopic rod is hinged to the vertical clamping block 11, and the output end of the lateral electric telescopic rod is hinged to the transverse clamping block 7.

[0033] The vertical clamping block 11 has a through hole, and the movable rod 14 passes through the through hole to penetrate the vertical clamping block 11.

[0034] In this embodiment, a pad 12 is fixedly connected to the horizontal clamping block 7, and a movable structure is provided inside the vertical clamping block 11. The movable structure includes a partition 13, a movable rod 14, a return spring 15, and a pad 2 16.
