In actual work, a worker coaxially extends the core strip 2 into the mounting hole 11; if the hole position required to be formed in the plastic product is coaxial with the mounting hole 11, a worker arranges the four insert standard parts 31 of the same type between the outer circular surface of the core strip 2 and the inner wall of the mounting hole 11 in a circumferential array around the axis of the core strip 2, so that the core strip 2 and the mounting hole 11 are coaxial; if the hole position to be formed on the plastic product deviates from the axis of the mounting hole 11 along the horizontal or vertical direction, a worker replaces two insert standard parts 31 of the core strip 2 along the deviation direction, increases the size of the insert standard part 31 of the core strip 2 close to the deviation to one side, enables the size of the insert standard part 31 along the deviation direction to be equal to the size of the original insert standard part 31 minus the deviation size, and enables the size of the insert standard part 31 of the core strip 2 away from the deviation to one side to be equal to the size of the original insert standard part 31 plus the deviation size along the deviation direction, so that the deviation of the core strip 2 relative to the axis of the mounting hole 11 is realized, and the requirement for forming the hole position on different batches of plastic products is further met.

Referring to fig. 2 and 3, in order to expand the application range of the injection mold core hole position rapid adjustment mechanism and meet the requirements of different sizes of hole positions of different plastic products, the outer wall of the core bar 2 is coaxially sleeved with a sleeve 4, the sleeve 4 is arranged in a circular tube shape, and the core bar 2 is embedded into the sleeve 4 and is in interference fit with the inner wall of the sleeve 4. The inner wall of the slide block 1, which is positioned at one side of the mounting hole 11 close to the cavity, extends inwards along the radial direction of the slide block to form a flange 12 for limiting the sleeve 4. When the size of the hole position formed on the plastic product is changed, a worker replaces the core strips 2 with different sizes and coaxially installs the core strips into the sleeve 4 until one end of the sleeve 4 close to the cavity is abutted against the flange 12; then, the insert standard part 31 is embedded between the sleeve 4 and the inner wall of the mounting hole 11; subsequently, the injection molding operation of the relevant plastic article is continued.

In order to improve the convenience of installing the insert standard part 31 on the corresponding position on the outer circular surface of the sleeve 4 by a worker, four limiting grooves 41 are circumferentially arrayed on the outer circular surface of the sleeve 4 around the axis of the sleeve, and the length direction of any limiting groove 41 is parallel to the axis direction of the sleeve 4; any insert standard part 31 is embedded into the limiting groove 41 along the length direction thereof, and slides relative to the limiting groove 41 along the length direction of the limiting groove 41, and any insert standard part 31 is in interference fit with the outer circular surface of the sleeve 4 and the corresponding inner wall of the mounting hole 11.

Meanwhile, in order to improve the convenience of the insert standard part 31 being inserted between the outer circular surface of the sleeve 4 and the inner wall of the mounting hole 11, guide inclined surfaces 32 are formed at two ends of any insert standard part 31 in the length direction.

The implementation principle of the injection mold core hole site quick adjustment mechanism of the embodiment of the application is as follows: in actual work, when the hole position required to be formed in the plastic product is coaxially arranged with the mounting hole 11, a worker coaxially extends the core bar 2 into the mounting hole 11 and then respectively inserts the four insert standard parts 31 of the same type into the corresponding limiting grooves 41; then, any insert standard part 31 is pushed, so that any insert standard part 31 slides along the length direction of the corresponding limiting groove 41 until any clamping block 311 is clamped and matched with the clamping groove 43, and the core bar 2 and the mounting hole 11 are coaxially arranged.

When a hole position needs to be formed on a plastic product and deviates relative to the axis of the mounting hole 11, a worker replaces two insert standard parts 31 of the core strip 2 in the deviation direction, the size of the insert standard part 31 of the core strip 2 close to one side in the deviation direction is equal to the size of the original insert standard part 31 minus the deviation dimension, the size of the insert standard part 31 of the core strip 2 away from one side in the deviation direction is equal to the size of the original insert standard part 31 plus the deviation dimension, and therefore the position of the core strip 2 is adjusted.

The position of the core strip 2 is adjusted by replacing the insert standard parts 31 with different sizes, so that a pair of dies can simultaneously meet the molding requirements of different hole sites of different batches of plastic products, the production quantity of injection molds is effectively reduced, and the production cost of enterprises is effectively saved; meanwhile, the hole position adjusting assembly is simple in structure, convenient for operation of workers and beneficial for improving the convenience of replacing the insert standard part 31.
