Description

Technical Field

[0001] The utility model relates to the technical field of inclined core demoulding structures, in particular to an inclined core demoulding structure. Background Art

[0002] The inclined pin ejection structure is a mechanism used in plastic or metal molds, which allows the molded product to move along a certain angle when the mold is opened, thereby achieving smooth demoulding of the undercut part.

[0003] According to a slant pin ejection structure disclosed in patent number CN218748836U, the energy taking part mainly utilizes the kinetic energy obtained from the movement of the slant pin seat along the guide rod to drive the translation part, so that the slide seat at the bottom end of the slant pin can obtain direct force control, so that the deflection torque received by the slant pin is greatly reduced, so that the inclination angle of the slant pin can be set larger, thereby improving the applicability.

[0004] However, in actual application, we can understand that the convex head is an important component of the inclined top structure, and its condition directly affects the smoothness and accuracy of the inclined top movement. If the convex head is worn, it may cause the trajectory of the inclined top movement to deviate, thereby affecting the precise closure of the mold and the molding quality of the product. Therefore, after the convex head has been used for a period of time, it is usually necessary to remove it for maintenance. However, in the technology of the above-mentioned comparative documents, we can understand that the convex head is installed and fixed by bolting. When people disassemble the convex head, they need to use tools to tighten the bolts, which makes the disassembly and installation of the convex head inconvenient. In addition, frequent tightening of the spiral can easily lead to serious wear of the thread, which makes the bolt unable to effectively engage during the tightening process, thereby reducing the reliability of the convex head after fixation.

The driving rod 404 can be conveniently controlled by the handle 405, and the movement of the driving rod 404 can drive the movement of the limiting rod 408.

[0032] Please refer to Figure 3 A convex head block 5 is arranged inside the fixing groove 401, and a symmetrical limiting hole is opened on the outer surface of the convex head block 5. By inserting the limiting rod 408 into the limiting hole opened on the outer surface of the convex head block 5, the convex head block 5 can be installed and fixed. The convex head block 5 is used to contact the external product that needs to be demolded.

As the gear 7 rolls, under the action of the threaded connection with the threaded rod 6, it can provide an inclined upward pulling force for the inclined block 2, thereby allowing the inclined block 2 to move upward more smoothly. At this time, under the connection action of the inclined pin 3, the external product that needs to be demolded can be ejected through the convex head block 5. As the convex head block 5 is used for a long time, when it is severely worn and needs to be disassembled for maintenance, people can control the sliding of the driving rod 404 away from each other through the two handles 405.

When the cam block 5 is in the fixed groove 401, the two driving rods 404 can be moved away from each other by the handle 405 again, and the cam block 5 can be placed in the fixing groove 401. At this time, by loosening the handle 405, the limiting rod 408 can be driven to reset and insert into the limiting hole on the cam block 5 under the pulling force of the spring 406, so that the cam block 5 can be installed more conveniently. By not bolting the cam block 5, people no longer need to use tools to tighten the bolts, which not only makes it easier for people to disassemble and install the cam block 5, but also avoids the situation that the bolts cannot be effectively engaged when tightened due to severe thread wear, thereby further improving the reliability of the cam block 5 after being fixed.
