Abstract
The utility model provides a mould hydro-cylinder locking mechanism relates to mould technical field, and the mould includes front formword and back template, one side of back template is fixed with the fixing base, and the cylinder is fixed the fixing base below, the output of cylinder is connected with the motion pole, the motion pole inserts in the slider of loosing core, the end of motion pole links up with the recess of fixed block lower part, fixed block one side is equipped with the boss, the boss embedded extremely in the front formword. The utility model discloses after the compound die, through inserting the motion pole in the slider of loosing core to the end of motion pole is inserted and is fixed in the fixed block recess in the template in the front, plays the effect of fixed motion pole, and further the slider of loosing core is fixed in the template in the front, prevents to penetrate gluey pressure and forces the slider of loosing core to retreat.
Description
Technical Field
The utility model belongs to the technical field of the mould technique and specifically relates to a mould hydro-cylinder locking mechanism.
Background
In the prior art, during injection molding, the in-and-out action of the core pulling of the mold in the front template is controlled by an oil cylinder, the oil cylinder drives the core pulling slide block to perform core pulling and resetting in the horizontal direction, and the oil cylinder is arranged on an oil cylinder fixing plate. The movement action of the scheme has no problem, but the mold is forced by the injection pressure when a product is injected, great backward retreating force can be generated, the core-pulling slide block can achieve the effect that the core-pulling slide block cannot retreat only by the stable reverse locking force, the injection pressure of the product is born by the oil pressure in the oil cylinder, the instability can be caused, and the piston in the oil cylinder can retreat. This is because the linear line of pure hydro-cylinder supports the slide, and the dynamics often is not enough, and the dynamics is not ensured. Therefore, the existing die cannot effectively control the back-off of the core-pulling sliding block, so that the production efficiency is low and the yield is not high.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides a mould hydro-cylinder locking mechanism.
The utility model discloses specifically adopt following technical scheme to realize:
the utility model provides a mould hydro-cylinder lock mechanism, mould include front bezel and back template, one side of back template is fixed with the fixing base, and the cylinder is fixed the fixing base below, the output of cylinder is connected with the motion pole, the motion pole inserts in the slider of loosing core, the end of motion pole links up with the recess of fixed block lower part, fixed block one side is equipped with the boss, the boss embedded extremely in the front bezel.
Preferably, the top of the fixed seat is provided with a sliding groove, and the core-pulling sliding block is placed in the sliding groove.
Preferably, the core-pulling slider is provided with an inclined through hole, the moving rod is inclined, and the inclination angle of the moving rod is the same as that of the through hole.
The utility model provides a mould hydro-cylinder lock mechanism, its beneficial effect lies in: after the mold is closed, the movable rod is inserted into the core-pulling sliding block, the tail end of the movable rod is inserted into a groove of the fixed block fixed on the front mold plate, the movable rod is fixed, the core-pulling sliding block is further fixed in the front mold plate, and the core-pulling sliding block is prevented from being forced to retreat by glue injection pressure.

Detailed Description
To further illustrate the embodiments, the present invention provides the accompanying drawings. The accompanying drawings, which are incorporated in and constitute a part of this disclosure, illustrate embodiments of the invention and, together with the description, serve to explain the principles of the embodiments. With these references, one of ordinary skill in the art will appreciate other possible embodiments and advantages of the present invention. Elements in the figures are not drawn to scale and like reference numerals are generally used to indicate like elements.
The present invention will now be further described with reference to the accompanying drawings and detailed description.
As shown in fig. 1-3, the reverse locking mechanism for the oil cylinder of the mold provided by the embodiment includes a front mold plate 1 and a rear mold plate 2, a fixing seat 3 is fixed on one side of the rear mold plate 2, an air cylinder 4 is fixed below the fixing seat 3, a sliding groove 5 is arranged at the top of the fixing seat 3, and a core-pulling sliding block 6 is placed in the sliding groove 5. The output of cylinder 4 is connected with motion pole 7, and during motion pole 7 inserted the slider 6 of loosing core, the perforation of slope was seted up to slider 6 of loosing core, and motion pole 7 is the slope form, and inclination is the same with perforated inclination. The end of motion pole 7 links up with recess 81 of 8 lower parts of fixed block, and 8 one sides of fixed block are equipped with boss 82, and boss 82 is embedded to be fixed to in the front forms 1.
The utility model provides a mould hydro-cylinder anti-lock mechanism, when the compound die, cylinder 4 drives the relative preceding template 1 of motion pole 7 along the perforation slope upward movement of the slider 6 of loosing core, in the slope upward movement in-process, in the slider 6 of will loosing core pushes into preceding template 2, accomplish the compound die action back, the end of motion pole 7 is inserted in the recess 81 of the fixed block 8 of fixed template 1 in the front of, play the effect of fixed motion pole 7, it is further fixed in preceding template 1 to loose core slider 6, prevent to penetrate gluey pressure and force the slider 6 of loosing core to retreat.
While the invention has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
