Detailed Description

The technical solution of the present invention will be further described in detail with reference to the following detailed description, but the present invention is not limited thereto.

Example 1:

as shown in fig. 1-7, a structure of an insert 2 convenient for disassembly and assembly includes a mold base 1, an insert 2 disposed on the mold base 1, a top shaft 3 disposed at the bottom of the insert 2, and a positioning shaft 4 connected to the insert 2 in a pluggable manner; the top shaft 3 is in running fit with the die holder 1, and the insert 2 and the positioning shaft 4 are respectively in sliding fit with the die holder 1; when the top shaft 3 rotates around the axis to a preset angle, the upper surface of the insert 2 is positioned on the outer side of the surface of the die holder 1.

The disassembly and assembly process comprises the steps that through the arrangement of the ejector shaft 3 and the positioning shaft 4, when the insert 2 on the die holder 1 is to be disassembled, the positioning shaft 4 on the die holder 1 is pulled, the positioning shaft 4 is pulled out to the outer side of the insert 2, the ejector shaft 3 is positioned at the bottom of the insert 2, the ejector shaft 3 is rotated, the rotating shaft rotates around the axis, until a preset angle is reached, the ejector shaft 3 pushes the bottom of the insert 2 to eject the insert 2, and the upper surface of the insert 2 is positioned on the outer side of the surface of the die holder 1 and can be manually clamped out; on the contrary, when the insert 2 is installed, the jacking shaft 3 is restored to the original position, the insert 2 is placed, the positioning shaft 4 is pushed to be connected with the insert 2, the installation of the insert 2 is completed, and the insert 2 structure which is small in size, simple in structure and convenient to disassemble and assemble is achieved.

The top shaft 3 has a specific structure that one end of the top shaft 3 is a top end 301, the top end 301 is provided with a concave portion 302 located in the radial direction of the top shaft 3, and the concave portion 302 is located right below the insert 2.

The principle of ejecting the insert 2 by the top shaft 3 is that, when the insert 2 is used normally, the insert 2 falls on the concave portion 302 of the top shaft 3, the concave portion 302 of the top shaft 3 contacts the bottom of the insert 2, the top shaft 3 is rotated, the concave portion 302 rotates along with the rotation of the top shaft 3, the concave portion 302 is separated from the insert 2, the distance from the axis of the concave portion 302 is smaller than the radius distance of the top shaft 3, and the part except the concave portion 302 contacts the bottom of the insert 2, so that the insert 2 can be ejected and pushed.

Preferably, the concave portion 302 is a plane attached to the bottom of the insert 2; the characteristics of large plane contact area and flat end surface are utilized to improve the stability of the insert 2 in the die holder 1, so that the connection is firmer.
