Abstract
The utility model relates to an injection mold's screw thread mechanism of loosing core, including motor and pivot, the top of pivot is equipped with the fashioned shaping piece of messenger's product, still includes action wheel, second gear and transition gear group, the action wheel with the motor is connected, the second gear with the pivot is connected, the action wheel passes through the transition gear group with the second gear transmission is connected. The transition gear set comprises a driven wheel and a first gear connected with the driven wheel, a belt is sleeved between the driving wheel and the driven wheel, and the first gear is meshed with the second gear. Compared with the prior art, the utility model discloses it is rotatory that well motor drives the pivot under the cooperation of action wheel, transition gear group and second gear to make into shape piece and product separation, accomplish the screw thread and loose core, loose core the process reliable and stable, prevent that the product from loosing core when impaired, greatly reduced the rejection rate, simple structure.
Description
Technical Field
The utility model relates to an injection mold's screw thread mechanism of loosing core belongs to injection mold technical field.
Background
After injection molding, holes, bosses, threads and other inverted-buckle forming positions of a product need to be subjected to core pulling before demolding due to the fact that the mold opening direction of the mold is different or the forming positions cannot be directly subjected to demolding. In the prior art, the structures such as a sliding block, an inclined top and an ejector rod are usually adopted to help demoulding the formed parts such as holes and bosses, but the structures are not suitable for the formed parts of the threads, the formed parts of the threads are forcibly subjected to core pulling, the products are easy to damage, and the rejection rate is high.
SUMMERY OF THE UTILITY MODEL
The utility model aims at the shortcoming of prior art, provide a mechanism is taken out core to screw thread that injection mold that stable loose core was taken out to screw thread back-off.
For realizing the purpose the utility model adopts the technical proposal that:
injection mold's screw thread mechanism of loosing core, including motor and pivot, the top of pivot is equipped with the shaping piece that makes the product shaping, still includes action wheel, second gear and transition gear train, the action wheel with the motor is connected, the second gear with the pivot is connected, the action wheel passes through the transition gear train with the second gear transmission is connected.
As a further optimization of the above technical solution: the transition gear set comprises a driven wheel and a first gear connected with the driven wheel, a belt is sleeved between the driving wheel and the driven wheel, and the first gear is meshed with the second gear.
As a further optimization of the above technical solution: the motor drives the driving wheel to rotate, the driven wheel, the first gear and the second gear also start to rotate, and therefore the rotating shaft starts to rotate.
As a further optimization of the above technical solution: the pivot with the second gear all is provided with two, two the second gear all with first gear meshes mutually.
Compared with the prior art, the motor drives the rotating shaft to rotate under the matching of the driving wheel, the transition gear set and the second gear, so that the forming block is separated from the product, the thread core pulling is completed, the core pulling process is stable and reliable, the product is prevented from being damaged during core pulling, the rejection rate is greatly reduced, and the structure is simple; set up the transition gear group and carry out the transmission to be connected with action wheel and second gear, provide sufficient space for the installation of motor and the rotation of pivot, prevent that the pivot of rotatory in-process can interfere with the motor mutually.
Drawings
Fig. 1 is a schematic perspective view of the present invention.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and the following detailed description. As shown in fig. 1, the screw core-pulling mechanism of the injection mold comprises a motor 1 and a rotating shaft 2, and a forming block 21 for forming a product is arranged at the top of the rotating shaft 2. The forming block 21 forms threads on the inner side of the product, and after injection molding is finished, the forming block 21 needs to be separated from the product. Still include action wheel 4, second gear 6 and transition gear train, action wheel 4 is connected with motor 1, and second gear 6 is connected with pivot 2, and action wheel 4 is connected with the transmission of second gear 6 through the transition gear train.
In the above technical scheme: the transition gear set comprises a driven wheel 3, a belt 5 and a first gear 7 connected with the driven wheel 3, the belt 5 is sleeved between the driving wheel 4 and the driven wheel 3, and the first gear 7 is meshed with the second gear 6. After the injection molding is finished, the motor 1 drives the driving wheel 4 to rotate, the driven wheel 3, the first gear 7 and the second gear 6 also start to rotate, and the rotating shaft 2 starts to rotate; meanwhile, the movable mold and the fixed mold are separated, the forming block 21 is gradually separated from the product, the thread core pulling is completed, the core pulling process is stable and reliable, the product is prevented from being damaged during core pulling, the rejection rate is greatly reduced, and the structure is simple. Set up the transition gear group and carry out the transmission to take turns 4 and second gear 6 and be connected, for the installation of motor 1 and the rotation of pivot 2 provide sufficient space, prevent that pivot 2 among the rotatory process can interfere with motor 1 mutually.
In the above technical scheme: the rotating shaft 2 and the second gears 6 are both provided with two gears, and the two second gears 6 are both meshed with the driven wheel 3. The two rotating shafts 2 can simultaneously form two internal thread structures on the product.
The foregoing has described in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations can be devised by those skilled in the art in light of the teachings of the present invention without undue experimentation. Therefore, all should fall into the protection scope of the utility model, the technical scheme that the design of this technical field technical personnel according to the utility model can be obtained through logic analysis, reasoning or limited experiment on prior art's basis, all should fall into.
