Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

The utility model relates to a game machine steering wheel is exclusively used in and is controlled emulation car skewed tooth ejection demoulding mechanism. As shown in fig. 2-4, the structure of the ejector pin type injection molding machine comprises a housing 1, an ejector pin 2 is inserted into the lower surface of the housing 1, as a preferred embodiment, the ejector pin 2 is an ejector pin on an injection molding machine, a bottom bearing 3 is arranged on the inner bottom wall of the housing 1, a side wall bearing 4 is arranged on the inner wall of the housing 1, a mold core 5 is arranged on the upper surface of the housing 1, a movable insert 6 is arranged inside the side wall bearing 4, and a bevel gear 7 is inserted into the movable insert 6.

Referring to fig. 2, the lower surface of the casing 1 is provided with a plurality of through holes, and the inside of the through holes is sleeved on the outer surface of the thimble 2. In addition, a plurality of hole grooves are formed in the outer surface of the shell 1, so that the practicability of the device is improved.

Referring to fig. 3, the bottom bearing 3 and the sidewall bearing 4 are made of steel materials, so that the bottom bearing 3 and the sidewall bearing 4 are not easy to damage and can be used for a long time. The mounting groove has been seted up to the four corners department of 1 upper surface of box body, and mould benevolence 5 fixed connection is in the inside of mounting groove. Referring to fig. 2, the movable insert 6 is detachably designed, and a hole groove is formed in the upper surface of the movable insert 6, so that the movable insert 6 is convenient to detach, and a person can replace the damaged movable insert 6 conveniently, thereby providing convenience for the person.

On the injection molding machine, the thimble 2 moves upwards, and then when the bevel gear 7 is ejected upwards by the thimble 2, the movable insert 6 rotates after receiving an upward thrust to drive the bottom bearing 3 and the side wall bearing 44 to rotate synchronously, and the rotation is stopped when the rotation height reaches the bottom of the bearing, and the bevel gear 7 is gradually separated from the mold cavity due to the rotation, so that the product damage is avoided, the free ejection and falling can be realized, finally, the injection molding machine drives the thimble 2 to descend, the equipment is automatically reset, and the next round of the bevel gear 7 is opened for demolding.

It can be seen from fig. 2 that when the helical gear product shown in fig. 3 is ejected upwards by the ejector pin 2, the helical gear ejection demoulding mechanism drives the bottom bearing 3 and the side wall bearing 4 to synchronously rotate through the arrangement of the bottom bearing 3, the side wall bearing 4 and the movable insert 6, so that when the helical gear 7 is ejected upwards by the ejector pin 2, the movable insert 6 rotates after receiving an upward thrust, and the helical gear 7 stops rotating when reaching the bottom of the bearing, and the helical gear 7 gradually breaks away from the die core 5 due to rotation, so that product damage is avoided, the helical gear can be ejected and fall off freely, and the mechanical bearing is used ingeniously, so that the device has a simple and practical structure, the design and development cost of the device is reduced, the problem that the helical gear 7 cannot be demoulded is effectively solved, the rapid demoulding effect of the helical gear 7 after injection moulding is realized, the customer requirements are met, and the expected target is reached.

The above is a detailed description of the way of demoulding the helical teeth of the plastic mould, and the disclosed mechanism can be implemented or used by a person skilled in the art. Various modifications to the demolding mechanism of the present invention will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other implementations without departing from the scope of the demolding mechanism of the present invention, and therefore, the demolding mechanism of the present invention will not be limited to the examples shown herein, but will be accorded the widest scope consistent with the principles and novel features disclosed herein.
