It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
In order to explain the technical solution of the present invention, the following description is made by using specific examples.
Only portions related to the embodiments of the present invention are shown for convenience of explanation.
With reference to fig. 1-4, the core pulling mechanism includes a fixing plate 1, a plurality of cores 2 are symmetrically arranged on the fixing plate about an axis, guide sleeves 3 are arranged on the cores, a slidable sliding block 4 is arranged above the fixing plate, an inverted T-shaped guide groove 5 is downwards arranged at the top of the sliding block along the length direction, a T-shaped inclined guide groove 6 is arranged at the bottom of the sliding block along the length direction, a matched straight guide rail 7 is embedded in the inverted T-shaped guide groove 5, an inclined guide rail 8 is further arranged on the fixing plate and embedded in the T-shaped inclined guide groove, the core pulling mechanism further includes a driving device 9, and the driving end of the driving device is connected to the corresponding position of the sliding block.
In the structure, a plurality of cores are arranged on the fixing plate and form a core-pulling mechanism together with the cores, and the core-pulling mechanism replaces manual work under the driving of the driving device to complete mold stripping and then takes out the insert placed on the core from a product. The hydraulic cylinder core-pulling mechanism is fixedly arranged at the corresponding position of the die equipment, and is communicated with an oil way through a hydraulic interface reserved in the forming equipment. The core-pulling mechanism is arranged on a mould template (not shown in the figure), wherein the guide sleeves penetrate through the back of the template one by one and are arranged in the corresponding guide sleeve holes, the mould cores penetrate through the template one by one, the head parts of the mould cores extend into a mould cavity and are used for forming one part of a product, and the straight guide rail is fixed on the template.
The guide sleeve is used for constraining the sliding directions of the mold core and the fixed plate, and when the sliding block moves on the straight guide rail, the fixed plate and the two groups of mold cores move downwards by utilizing the thrust generated by the inclined guide groove on the inclined guide rail and the constraint of the guide sleeve, so that the mold core is drawn out of a product. The straight guide rail that the embedding was installed in the shape of falling T guide way is fixed in mould relevant position, the inclined plane guide rail embedding is installed in T type inclined plane guide way, and the inclined plane guide rail mainly is for the convenience of the inclined plane guide rail slides along T type inclined plane guide way direction in T type inclined plane guide way in this embodiment, when the sliding block drive inclined plane guide rail that is equipped with T type inclined plane guide way slides, makes fixed plate and two sets of cores remove downwards under the restraint of uide bushing again, and then the core is taken out from the goods.
As a preferable structure, the front end of the sliding block is vertically provided with a connecting groove 10, a pushing block is embedded in the connecting groove, and the driving end of the driving device is connected to the pushing block 15.
In this embodiment, the core pulling device utilizes a driving device to provide driving force, in this embodiment, the driving device includes a hydraulic cylinder, a piston rod of the hydraulic cylinder pushes a pushing block installed in a connecting groove to drive a sliding block to move, the sliding block moves horizontally forward under the guiding constraint of a straight guide rail, and simultaneously under the driving of a component force of an inclined guide rail and the constraint action of a guide sleeve, the inclined guide rail is driven to move vertically downward, and the inclined guide rail is fixed on a fixed plate, so that the fixed plate and two groups of cores are driven to move downward, and the cores are pulled out from a product.
After the part is taken, the oil cylinder moves reversely, the piston rod pulls the sliding block to move horizontally and linearly, the sliding block drives the inclined plane guide rail to move upwards, so that the mold core moves upwards to reset, and the production of the next mold is continued.
Further as a preferred structure, the fixing plate comprises an upper fixing plate 11 and a lower fixing plate 12, the upper fixing plate is provided with a matched core fixing groove 13 corresponding to the core, the upper fixing plate is also provided with a guide rail mounting groove 14 corresponding to the inclined guide rail, and the lower fixing plate is screwed into the mounting screw and locked to the inclined guide rail. The upper fixing plate is mainly used for bearing the core pulling mechanism; in this embodiment, the core is a cylindrical boss structure, and when the core is installed, only the top of the core needs to penetrate through the core fixing groove matched with the top of the core, and then the upper fixing plate and the lower fixing plate are fixedly installed, so that the installation and fixation of the core can be realized.
In the structure, a lower limiting block 16 is arranged on the bottom surface of the lower fixing plate corresponding to the mold core, and is screwed into a fixing screw and locked to the lower fixing plate; and an upper limiting block 17 is arranged between the cores in the same group and outside the sliding block. The lower limiting block and the upper limiting block mainly play a role in limiting the whole hydraulic core pulling mechanism at the corresponding position of the die.
In summary, the following steps: the hydraulic core-pulling mechanism mainly utilizes the hydraulic cylinder to drive the sliding block to do linear reciprocating motion, and through the matching of the guide groove on the sliding block and the inclined guide rail, the fixed plate moves perpendicular to the motion direction of the piston rod, so that the core is driven to move, the purpose that the core with larger holding force in the product is pulled out from the product before a workpiece is taken is achieved, and when the mold is closed next time, the hydraulic cylinder reversely acts to reset the core.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not intended to limit the present invention, and any modifications, equivalents, improvements, etc. made within the spirit and principles of the present invention should be included within the scope of the present invention.
