Abstract
The utility model discloses a structural improvement on a die clamper, and the structural improvement brings better practical efficacy to the die clamper. The structure improvement is mainly characterized in that a front oil pressure chamber, a rear oil pressure chamber, an extension chamber, a front oil hole and a rear oil hole are arranged on a cylinder body; a slide block and an auxiliary spring are arranged in the front and the rear oil pressure chambers respectively in a grouping way; an auxiliary rod, a return spring and a linkage block are arranged in the extension chamber in a grouping way; and the auxiliary rod is pivoted with a gripping head. Through the structure, a die can be normally gripped and released, especially when oil pressure has failures or no oil pressure is available, the elasticity of the auxiliary spring can still help in gripping the die, thereby preventing the die from slip easily or dropping off.
Description
Technical field
The utility model relates to the die clamper structure, particularly relates to a kind of die clamper architecture advances.
Background technology
The structure of prior oil pressure die clamper, all be simple oil pressure act on piston-advance and promote chuck folder fixed mold object or oppositely oil pressure piston is retreated and discharges, therefore have following shortcoming: when the oil pressure unit fault does not have oil pressure or personnel operation and removes oil pressure accidentally, its piston promptly is slidably, cause the chuck mistake to discharge, mold articles promptly can wrong slip problem, especially, when mold articles is the suspension type state, the chuck mistake discharges the i.e. danger that can cause mold articles to drop.In other words, existing die clamper does not have the safety structure function.
Summary of the invention
The purpose of this utility model provides a kind of die clamper architecture advances, be provided with secondary spring in the back hydraulic chamber of its cylinder body, but the elastic force auxiliary top sliding motion block of secondary spring, sliding shoe is pushing tow chuck and press from both sides the fixed mold object again, therefore, the elastic force that still has secondary spring when cylinder body does not have oil pressure acts on chuck folder fixed mold object, reaches and takes precautions against the insurance effect that the mold articles mistake is slided or mistake drops.
For achieving the above object, the utility model provides a kind of die clamper architecture advances, wherein: a cylinder body has preceding oil through, back oil through, chuck, be set as in the cylinder body have preceding hydraulic chamber, the back hydraulic chamber, be provided with sliding shoe in the forward and backward hydraulic chamber, the sliding shoe pushing tow is in chuck, the chuck folder is due to mold articles, be provided with the secondary spring pushing tow in the back hydraulic chamber in sliding shoe, when back hydraulic chamber does not have oil pressure pushing tow sliding shoe, the elastic force of secondary spring still pushing tow reaches the effect of taking precautions against the mold articles misoperation in sliding shoe.
In the above-mentioned die clamper architecture advances, be provided with flexible chamber in this cylinder body and organize and be provided with auxiliary rod, linked block, back extractor, auxiliary rod one end is articulated in chuck, and the elastic force by the back extractor retreats auxiliary rod, linked block, does not press from both sides the fixed mold object and chuck is discharged.
Effect of the present utility model, effect are as follows: entered in the hydraulic chamber of back by back oil through input oil pressure during the utility model folder fixed mold object, and the oil pressure of hydraulic chamber before getting rid of by preceding oil through, and promote sliding shoe pushing tow chuck, promptly get the function of chuck folder fixed mold object.When desire is removed folder regularly, enter preceding hydraulic chamber by preceding oil through input oil pressure, and get rid of the oil pressure of back hydraulic chamber by the back oil through, cooperate the back extractor in the flexible chamber, back that linked block, auxiliary rod are retreated again, promptly be can spur chuck no longer to press from both sides the fixed mold object.When oil pressure fault or back hydraulic chamber when not having oil pressure, this moment is because of having the power stretch of secondary spring, and still but pushing tow makes still retaining clip fixed mold object of chuck in sliding shoe, thereby can take precautions against the mold articles mistake and slide or drop (mold articles is the suspension type state) by mistake, in other words, the effect that has insurance location, insurance safety by secondary spring.

The specific embodiment
The utility model promptly is in order to overcome the shortcoming of above-mentioned existing die clamper, a kind of die clamper with safety structure function is provided, see also Fig. 1, Fig. 2, Fig. 3, one cylinder body 10 has preceding oil through 11, back oil through 12, chuck 13, be provided with sliding shoe 15 in the cylinder body and have preceding hydraulic chamber 14, back hydraulic chamber 140, and be provided with secondary spring 16 pushing tows in sliding shoe 15,15 pushing tows of sliding shoe press from both sides fixed mold object 20 in chuck 13, therefore, when back hydraulic chamber 140 no oil pressures, still can be by the elastic force additional lock fixed mold object of secondary spring 16.
Please consult Fig. 1 again, Fig. 2, Fig. 3, Fig. 4 and Fig. 5, one cylinder body 10 has preceding oil through 11, back oil through 12, the chuck 13 of folder fixed mold object 20, be set as in the cylinder body 10 and have preceding hydraulic chamber 14, back hydraulic chamber 140, flexible chamber 17, before, back hydraulic chamber 14, be provided with sliding shoe 15 in 140, be provided with secondary spring 16 pushing tows in the back hydraulic chamber 140 in sliding shoe 15, sliding shoe 15 pushing tows are in chuck 13, be provided with auxiliary rod 18 in the flexible chamber 17, auxiliary rod 18 rear ends have linked block 190, and being provided with back extractor 19 pushing tows in linked block 190, auxiliary rod 18 front ends then are articulated in chuck 13.
Effect of the present utility model, effect: as shown in Figure 3, enter in the hydraulic chamber 140 of back by back oil through 12 input oil pressure during folder fixed mold object 20, and the oil pressure of hydraulic chamber 14 before getting rid of by preceding oil through 11, and promote sliding shoe 15 pushing tow chucks 13, promptly get the function of chuck 13 folder fixed mold objects 20.When desire is removed folder regularly, as shown in Figure 4, enter preceding hydraulic chamber 14 by preceding oil through 11 input oil pressure, and get rid of the oil pressure of back hydraulic chamber 140 by back oil through 12, cooperating the back extractor 19 in the flexible chamber 17, back that linked block 190, auxiliary rod 18 are retreated again, promptly is can spur chuck 13 no longer to press from both sides fixed mold object 20.When oil pressure fault or back hydraulic chamber 140 no oil pressures, as shown in Figure 5, this moment is because of having the power stretch of secondary spring 16, and still but pushing tow makes still retaining clip fixed mold object 20 of chuck 13 in sliding shoe 15, thereby can take precautions against mold articles 20 mistakes and slide or drop (mold articles 20 is the suspension type state) by mistake, in other words, the effect that has insurance location, insurance safety by secondary spring 16.
