Description

Clamp structure

This creation is a type of clamp structure, especially a clamp that can be used for punching, injection or die-casting machines to clamp molds and can be quickly replaced.

In the past, the punching machine and the injection machine required a lot of manpower, material resources and time to replace the mold, which increased the production cost and the output efficiency was also low. At present, the production trend of the industry is mainly based on a small amount of diversity, so high-frequency replacement is imperative, and the ability to change the efficiency of mold change has long been an important automated industrial process. Most industrial engineering today adopts a rapid die change system to shorten mold change time, production start time and adjustment time, while the rapid die change system includes a clamp, a lifter, a mold shifting arm, and a power unit through different devices. The structure allows the user to speed up the process of changing the mold and clamping the mold, completely reducing the mold change time.

In the rapid die change system, the clamp must be able to clamp or release the mold object at a high frequency, and strongly press the fixed mold object to prevent falling or sliding, maintain the accuracy of the positioning of the mold object, and avoid the adverse effect of the positioning of the mold object. The yield of the output product.

There are two forms of conventional clamps: (1) Straight-pull clamps. Referring to the first and second figures, the straight pull type clamp is small in size and can be mounted on a table or a slider of a punching machine, an injection machine and a die casting machine having a small internal space. However, when a straight pull type clamp is used, the U-shaped groove 2 is provided on the mold object 1 for the straight pull type clamp to be installed therein, and the clamp piece 3 is controlled by the piston 4 to move the upper and lower pieces to clamp the mold object 2. Since the mold object 2 is clamped by applying pressure vertically, the force is strong and the stability is extremely high. However, not all mold objects can be designed with U-shaped grooves, so the type of mold objects is limited. (2) Platen clamps. Referring to the third and fourth figures, the plate-type clamp adopts a lever type structure, the hydraulic piston 6 pushes one end of the clamping block 5, and the other end of the clamping block 5 is lowered to clamp the mold object 7. The advantage is that the mold object is additionally provided with a U-shaped groove for the use of the clamp when the straight pull type clamp is used. However, the disadvantage is that the plate-type clamp does not apply pressure to the mold object vertically, but is clamped on the side of the mold, and the clamping stability is low, and the positioning adjustment time is longer after the mold change, thereby reducing the production efficiency. The pressure plate type clamp is installed on the T-shaped groove of the table table or the slider, and the lever structure must have a force-supporting point. If the design is bad, the plate or the slider of the machine may be stressed, thereby damaging the machine table or Slider. (See patent No. M526484).

The present invention is to improve the above-mentioned shortcomings. The main technology and purpose is to provide a clamp structure comprising: a fixed seat, the fixed seat is provided with a hydraulic cylinder; an oil seal, the oil seal has a perforation, a group The clamping block is disposed at the lower end of the hydraulic cylinder; the clamping block is disposed in the hydraulic cylinder, and the hydraulic cylinder controls the up and down displacement, so that the clamping block can pass through the perforation; a spring is provided Outside the clamping block, to assist in resetting the clamping block. Wherein the upper end of the clamping block may have a groove for providing a gasket. The utility model further comprises a fitting seat, the fitting seat is fixed on the lower end of the fixing seat, so that the clamp structure can be embedded in the machine table, and the fitting seat can further have a fitting block, which can be according to different machine tables and mold requirements. Replace the fittings of different lengths, heights and shapes.

Please refer to the fifth to seventh figures, which is a clamp structure, comprising: a fixing base 10, the fixing base 10 is provided with a hydraulic cylinder 11; an oil seal 12 having a perforation 120, which is assembled on the oil a clamping block 13 is disposed at the lower end of the cylinder 11 , and the clamping block 13 is disposed in the hydraulic cylinder 11 . The hydraulic cylinder 11 controls the up and down displacement, so that the clamping block 13 can pass through the perforation of the oil seal 12 . a hole 120 for clamping the mold object W; a spring 14 disposed outside the clamping block 13 for assisting the resetting of the clamping block 13; a fitting seat 20 to which the fitting seat 20 is fixed The lower end allows the clamp structure to be embedded in the mounting table or the slider. In this way, the fixing base 10 is held horizontally against the machine table, so that when the clamping device structure is used, the fulcrum stress when the clamping plate clamp clamps the mold object is not generated.

Although the structure of the present clamp is like a plate-type clamp, the mold object W is mounted on the side of the mold, but the clamping method is not a conventional clamping plate clamp, but is applied vertically. The pressure is directly clamped to achieve a strong, stable and accurate clamping function, which effectively prevents the mold object from falling off or sliding, and does not need to have a U-shaped groove like a straight pull type end mold, which can reduce the mold. Object design cost.

In addition, the fitting seat 20 can further have at least one fitting block 200 structure, and the machine table, the table disk or the slider to be embedded in the clip body is provided with a fitting groove shaped with respect to the shape of the fitting block. When the clamping device is engaged with the machine table, only the fitting seat 20 needs to be embedded, and is directly locked by the fitting block 200, and can be quickly replaced without additional screw locking.

The fitting seat 20 can be replaced with different lengths, heights and shapes of the fitting seat 20 according to different punching machines, injection machines, die casting machines or other processing machines and different mold objects, so as to meet a small variety of industrial production trends. .

According to the above structure, the following functions and advantages can be obtained: (1) The structure of the original clamp is clamped by a direct pressure application of vertical pressure to achieve a strong, stable and accurate clamping function, thereby effectively preventing the mold object W from falling off or slide. (2) Using the creation of the mold clamping structure, the mold object W does not need to be provided with a U-shaped groove for the clamp to be installed, and has the effect of reducing the design cost of the mold object. (3) The fitting seat 20 of the present clipper structure can be replaced according to different punching machines, injection machines, die casting machines or other processing machines and different molds, and has universal utility, and no need to configure different types. Clamp. (4) The creation of the clipper structure has the powerful, stable and precise effect of the conventional straight pull type clamp, and the press plate type clamper does not need the U-shaped groove for the mold object, and is suitable for most mold objects. The advantages.

In summary, this creation has a groundbreaking structure, and has improved design and creation content, while at the same time achieving industrial use and progress, and this creation has not been seen in any information that can be known to the public. It is novel, when it meets the requirements of the Patent Law and Regulations, it proposes a new type of patent application according to law, and asks the board of directors to grant legal patent rights to the princess.

Only the above-mentioned ones are only one of the preferred embodiments of the present invention, and the scope of implementation of the present invention cannot be limited accordingly; that is, the equal changes and modifications created by the patent application scope of this creation should still be covered by this creation patent. range.
