Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

As shown in fig. 1, 2 and 3, a limiting column protection structure of a mold includes: the upper die plate 100, the lower die plate 200, go up spacing post 300, lower spacing post 400 and protective sheath 500, the upper die plate 100 can move towards the lower die plate 200, and be the compound die process when the upper die plate 100 is close to with the lower die plate 200, be the die sinking process when the upper die plate 100 separates with the lower die plate 200, and at the compound die in-process, protective sheath 500 can prevent that the hose from being pinched brokenly and prevent that personnel from being hindered by the clamp.

It should be noted here that in some special molds, a large number of cylinders or oil cylinders may be installed due to actual processing requirements, so that a large number of hoses (air pipes or oil pipes) are connected, and when the mold works, the hoses may move to be clamped by the upper limiting column 300 and the lower limiting column 400 which are close to each other, so that the hoses are broken.

The upper template 100 and the lower template 200 are arranged in an up-down corresponding manner, the upper limiting column 300 is connected with the upper template 100, the lower limiting column 400 is connected with the lower template 200, and the upper limiting column 300 and the lower limiting column 400 are arranged in an up-down corresponding manner.

Preferably, the upper mold plate 100 is movable, and can move toward the lower mold plate 200, and when it is lowered to a certain position, the upper limiting column 300 and the lower limiting column 400 collide together, so as to limit the upper mold plate 100 from further lowering, which can perform a limiting function.

It should be noted here that in the existing spacing post structure, there is a risk of crushing the hose for some molds with hose by not having any shielding or protection measures.

The protective sleeve 500 is sleeved on the lower limiting column 400, the upper limiting column 300 is located in the protective sleeve 500 when the upper template 100 and the lower template 200 are separated, and the upper limiting column 300 extends into the protective sleeve 500 and is connected with the lower limiting column 400 in an abutting mode when the upper template 100 and the lower template 200 are folded.

Preferably, the protective sheath 500 is a tubular structure, when the upper template 100 is separated from the lower template 200, that is, when the distance between the upper template 100 and the lower template 200 is the largest, the upper limiting post 300 is located in the protective sheath 500, and because the protective sheath 500 is sleeved on the lower limiting post 400, the hose cannot pass through the outer wall of the protective sheath 500 and enter between the upper limiting post 300 and the lower limiting post 400, and when the mold is closed, the upper limiting post 300 penetrates through the protective sheath 500 and is abutted against and connected with the lower limiting post 400, and cannot be pressed against various hoses.

In this embodiment, the protective cover 500 can prevent a hose (air pipe or oil pipe) or a person from being caught by the stopper post during mold clamping, and thus can provide an effect of protecting the hose and the person.

As shown in fig. 1, 2, and 3, based on the above embodiment, the protective sheath 500 includes a lower sheath body 510 and an upper sheath body 520, the lower sheath body 510 and the upper sheath body 520 are integrally connected, the lower positioning post 400 is sleeved on the lower sheath body 510, and the upper positioning post 300 is inserted into the upper sheath body 520.

Preferably, the sheath 500 is a whole tubular structure, but can be divided into a lower sheath 510 and an upper sheath 520 from the function point of view, the lower sheath 510 is the lower part of the sheath 500, the upper sheath 520 is the upper part of the sheath 500, when the mold is in the mold opening state, the upper positioning post 300 is located in the upper sheath 520, so no matter how the upper mold plate 100 moves, the upper positioning post 300 can only be located in the upper sheath 520, so that the upper sheath 520 blocks the hose, and the hose or other objects can enter between the upper positioning post 300 and the lower positioning post 400.

As shown in fig. 1 and 3, in the above embodiment, a gap 600 is formed between the upper positioning post 300 and the lower positioning post 400, and the gap 600 is located in the upper sleeve body 520.

Preferably, when the upper mold plate 100 moves towards the lower mold plate 200, the gap 600 is gradually reduced, that is, the upper limiting column 300 and the lower limiting column 400 are close to each other and finally collide with each other, in an actual structure, since the upper limiting column 300 and the lower limiting column 400 are both located in the protective sleeve 500, the gap 600 therebetween is also necessarily located in the upper sleeve 520, and the hose cannot pass through the upper sleeve 520 and enter the gap 600, so that the hose can be prevented from being pinched by the upper limiting column 300 and the lower limiting column 400 when the mold is closed.

As shown in fig. 1, 2 and 3, on the basis of the above embodiments, the lower sleeve 510 is provided with a first limiting hole 530, the lower limiting post 400 is provided with a second limiting hole 410 and a limiting pin (not shown), the first limiting hole 530 is aligned with the second limiting hole 410, and the limiting pin passes through the first limiting hole 530 and penetrates the second limiting hole 410, so that the protective sleeve 500 is fixedly connected with the lower limiting post 400.

Preferably, protective sheath 500 detachable is connected with spacing post 400 down, and the spacer pin is bolted construction, and in actual structure, only need insert first spacing hole 530 and the spacing hole 410 of second with spacer pin or bolt, just can make protective sheath 500 be fixed in spacing post 400 down, and be fixed in spacing post 400 down with protective sheath 500, can not influence spacing post 300 and remove, but also convenient to detach.

As shown in fig. 1, 2 and 3, in the above embodiment, a first chamfer 310 is provided at an end of the upper limiting post 300, a second chamfer 420 is provided at an end of the lower limiting post 400, and a testing portion (not shown) is formed between the first chamfer 310 and the second chamfer 420 when the upper limiting post 300 is abutted against the lower limiting post 400.

Preferably, a circle of first chamfer 310 is formed on the lower end surface of the upper limit post 300, a circle of second chamfer 420 is formed on the upper end surface of the lower limit post 400, and after the upper limit post 300 is abutted against the lower limit post 400, an annular test part is formed between the first chamfer 310 and the second chamfer 420 due to the existence of the chamfer.

Because the mould is adding man-hour, go up the mould and need just in time with the work piece laminating after the compound die, and in actual production process, go up the lower mould when the compound die, probably because go up spacing post 300 and spacing post 400 overlength or short down for cope match-plate pattern 100 can't move to the exact position, just so lead to the unable accurate processing work piece of mould, and after having set up the chamfer, can take off protective sheath 500 before processing, then carry out the simulation test to observe through test section.

During testing, the upper die and the lower die can be in a die closing state, and then whether the upper limiting column 300 and the lower limiting column 400 are actually abutted together is observed through a testing part formed by two chamfers, or whether the upper die and the lower die are just in contact with a workpiece or not is observed through the testing part when the upper limiting column 300 and the lower limiting column 400 are in abutting connection.

As shown in fig. 1 and 3, in the above embodiment, the upper sheath body 520 is in clearance fit with the upper positioning post 300, and the lower sheath body 510 is in clearance fit with the lower positioning post 400. Preferably, the upper positioning post 300 can be smoothly moved in the upper sheath body 520, and the hose can be prevented from entering between the upper positioning post 300 and the lower positioning post 400 through the gap between the upper sheath body 520 and the upper positioning post 300, so that the safety of the hose and personnel can be ensured.
