As shown in fig. 5, a mounting cavity of a notch 311 is opened on a surface of the mounting seat 31 facing the ejector rod 51, and one end of the ejector rod 51 is inserted into the mounting cavity through the notch 311. For example, the top surface of the ejector rod 51 has a boss, a step surface is formed between the boss and the top surface of the ejector rod 51, an inward recessed clamping groove is formed in the outer wall surface of the boss, the clamping groove is communicated with the step surface, when the ejector rod 51 is assembled with the mounting seat 31, the boss is embedded into the mounting inner cavity, the clamping groove is suitable for being embedded into the opening 311, the bottom of the mounting seat 31 is lapped on the step surface, the mounting seat 31 is detachably connected with the boss by a fastener, for example, the horizontally arranged fastener is a screw or a screw.
When actually processing a product, the length of the first insert 32 on the second insert 3 protruding from the mounting seat 31 should not be too large, and if the protruding length is too large, the processing accuracy of the cavity surface on the second insert 33 is not required.
In order to ensure that the processing precision of the cavity surface of the second insert 3 meets the requirement, for example, when the protrusion length is less than or equal to a preset value, for example, the preset value is 15mm, the second insert 3 is adopted; when the protruding length is greater than 15mm, the second insert 3 includes not only the mounting seat 31 and the first insert 32, but also a second insert 33 extending outward relative to the mounting seat 31, the cavity surface of the second insert 3 is formed by the cavity surface of the first insert 32 on the first insert 32 and the cavity surface of the second insert 33, so as to extend the whole insert of the second insert 3, and the first insert 32 and the second insert 33 are detachably connected by a second fixing member 42 avoiding the cavity surfaces of the first insert 32 and the second insert 33.
That is, the first insert 32 and the second insert 33 are separately manufactured to ensure the machining accuracy of the respective inserts, and detachably coupled by the second fixing member 42 avoiding the cavity surfaces of the first insert 32 and the second insert 33 to ensure the integrity of the cavity surface of the second insert 3, and the second insert 33 is generally used to shield the first fixing member.
For example, the cavity surfaces of the second insert 33 and the first insert 32 are located on the top surfaces thereof, and the first insert 32 and the second insert 33 are located on the side of the mounting seat 31, at which time the second fixing member 42 is detachably attached avoiding the top surfaces of the first insert 32 and the second insert 33. For example, along the horizontal direction, the side walls of the first insert 32 and the second insert 33 are respectively provided with a mounting hole, the second fixing member 42 is inserted into the two mounting holes to fixedly connect the first insert 32 and the second insert 33, and the second fixing member 42 is preferably a screw or a bolt.

Similarly, the side walls of the two second inserts 33 and the first insert 32 are provided with horizontally extending mounting holes, and the second fixing member sequentially passes through the mounting holes of the two second inserts 33 and the first insert 32 to fixedly connect the two second inserts 33 and the first insert 32, and correspondingly, the second insert 3 is integrally T-shaped.
The cavity surfaces of the first and second inserts 32, 33 are preferably arcuate, or inclined, or otherwise. The shape of the cavity surface of the moving core is determined by the shape of the product to be processed, for example, the shape of the product is S-shaped, it is necessary that the cavity surface of the moving core is S-shaped, and correspondingly, the cavity surface of the moving core main body 1, the cavity surface of the first insert 2, and the cavity surface of the second insert 3 are respectively allocated with partial S-shaped shapes, and the whole is S-shaped.
As shown in fig. 1, 2, and 3, one side (for example, the right side in the drawings) of the outer side wall of the first insert 2 abuts against the inner wall surface of the second cavity 11 via an inclined first guide surface, and the first guide surface functions as a guide to facilitate sliding the first insert 2 into the second cavity 11 along the first guide surface or taking it out of the second cavity 11. For example, a first inclined guide surface is provided on one side of the outer wall surface of the first insert 2, and an inclined surface that fits the first guide surface is provided at a corresponding position on the second cavity 11, and in fig. 1, the inclination angle of the first guide surface with respect to the horizontal direction is preferably in the range of 0.5 degrees to 20 degrees, for example, 0.5 degrees, 2 degrees, 5 degrees, 8 degrees, 13 degrees, 15 degrees, 18 degrees, 19 degrees, 20 degrees, and so on.
Similarly, one side (the right side in fig. 2) of the outer side wall of the second insert 3 abuts against the inner wall surface of the first cavity 21 through an inclined second guide surface, and the second guide surface also plays a role in guiding, so that the second insert 3 can slide into the first cavity 21 or slide out of the first cavity 21 along the second guide surface.
