Description

A combined mold opening device

technical field

The utility model belongs to the field of rubber manufacturing equipment, in particular to a combined mold opening device.

Background technique

Flat vulcanization requires the use of flat vulcanization molds of various specifications. For example, some small rubber strength test piece molds are 100mm long, 100mm wide, and only 10mm thick; there are also some large flat vulcanization molds that are 800mm long, 600mm wide, and 300mm thick, which require a lot of tools and labor when opening the mold. . In order not to affect the cavity design and the overall force of the mold, the shapes of the opening slots reserved for the above-mentioned flat vulcanization molds are also different. There are different shapes and sizes of opening slots such as square, rectangle, circle, triangle and even hexagon. The mold opening tool requires a different shape of the opening tip to be inserted into the opening slot to pry open these vulcanized molds. The above situation results in the need to manufacture a variety of mold-opening tools with different lengths and shapes, which is expensive to manufacture and inconvenient to carry.

Utility model content

The purpose of the utility model is to provide a novel combined mold opening device, which is suitable for the mold opening of different types of flat vulcanization molds, reduces the number of carrying common mold opening tools, and avoids damage to the flat vulcanization mold due to the unsuitable mold opening tools. Strong performance, convenient operation, time-saving and labor-saving, greatly improving work efficiency.

The technical scheme that realizes the purpose of the present utility model is:

A combined mold-opening device comprises a main body rod and a plurality of mold-opening ends. During operation, any one of the mold-opening ends is sleeved and fixed at one end of the main body rod.

Further, one end of the main body rod is provided with a square tunnel along the rod direction, and the die opening end is provided with a square tenon matched with the square tunnel.

Another option is that one end of the main body rod is provided with a square tenon along the rod direction, and the mold opening end is provided with a square tunnel matched with the square tenon.

Further, the square tenon and/or the square tunnel are magnetic.

Further, it also includes a support rod, the top of the support rod is provided with a hoop matched with the main body rod, and when in use, the main body rod is inserted into the hoop.

Further, the length of the support rod is adjustable.

Further, the other end of the main body rod is provided with a non-slip handle.

The mold opening device uses the corresponding mold opening head according to the shape of the mold opening groove, and combines it with the end of the main body rod. For small vulcanized molds, insert the mold opening end head into the mold opening groove, and directly use the main body rod to pry it open. Large vulcanization molds can be equipped with support rods, insert the mold opening end into the mold opening groove, provide a suitable fulcrum for the main rod, and use the lever principle to pry open the vulcanization mold, which saves effort and does not cause damage to the mold, and the length of the support rod can be adjusted. It can be adjusted to adapt to molds of different thicknesses.

The utility model unifies and standardizes the structure of the existing mold-opening tools, one main body rod can be connected to the mold-opening end heads adapted to various mold-opening groove shapes, saves the cost, and can also adapt to multiple vulcanizations with different thicknesses The mold opening device can save time and effort, and does not damage the flat vulcanization mold. The mold opening device has strong practicability, simple operation, convenient storage, and obvious improvement of work efficiency.

Detailed ways

The present utility model will be described in detail below with reference to the embodiments.

1 and 2, a combined mold opening device includes a main body rod 1 and a number of mold opening ends 3, one end of the main body rod 1 is provided with a square tunnel 1-1 along the rod direction, and the mold opening end is provided with a The square tunnel 1-1 matches the square tenon 3-1, the square tunnel 1-1 is magnetic, and the use of the square tunnel and tenon combination is beneficial to the main body rod 1 when it rotates. The mold opening method can improve the mold opening efficiency. The end of the main body rod 1 is equipped with magnetism, which makes the disassembly and assembly of the main body rod 1 and the mold opening end head 2 more convenient and fast.

In this embodiment, a support rod 2 is also provided. The top of the support rod 2 is provided with a hoop 2-1 matched with the main body rod 2. When in use, the main body rod 1 is inserted into the hoop ring 2-1. By adjusting the hoop ring 2-1 At the position on the main body rod 1, the prying force can be adjusted to achieve a labor-saving effect. The length of the support rod 2 can be adjusted. The specific structure can be but not limited to the use of screw rotation type or sleeve telescopic type. The adjustment can be adapted to the different thickness of the vulcanization mold,

The other end of the main body rod 1 is provided with a non-slip handle 1-2, which is convenient for workers to hold and operate, and improves comfort.
