[0038] As Figure 1-12 shown, an insert and lifter combined structure is provided in an embodiment of the present application, which includes a template 1, an inner mold 2, a lifter 3, and a vulnerable component. A groove matching the inner mold 2 is provided on the top surface of the template 1, and the inner mold 2 is arranged in the groove;

[0039] Both the lifter 3 and the vulnerable component are inserted inside the inner mold 2, and the lifter 3 and the vulnerable component are distributed at intervals;

[0040] The lifter 3 includes a lifter main body 31 and a lifter head 32. The lifter head 32 is arranged at the upper end of the lifter main body 31 and is detachably connected to the lifter main body 31;

[0041] The lower end of the lifter main body 31 penetrates through the bottom surface of the inner mold 2 and inserts into the template 1;

[0042] Wing plates 33 are arranged at the edge of the lifter head 32;

[0043] The vulnerable component includes an insert group 4 and a wedge block 5. The wedge block 5 is used to limit the insert group 4. The wedge block 5 is located below the wing plates 33, and the upper end of the wedge block 5 abuts against the wing plates 33 and is limited by the wing plates 33.

[0044] In this embodiment, the lifter main body 31 and the lifter head 32 are connected by bolts. When the insert 41 of the wire groove is damaged during the production process, first remove the bolts between the lifter main body 31 and the lifter head 32, and then only need to remove the lifter head 32. The lifter main body 31 does not need to be disassembled. At this time, the wing plates 33 no longer limit the upper end of the wedge block 5. Then, pull out the wedge block 5. After pulling out the wedge block 5, a hollow groove is formed on the side of the insert 41 close to the wedge block 5. At this time, pull the insert 41 of the wire groove towards the hollow groove to loosen the insert 41, and then it can be easily taken out for spare part replacement;

[0045] By separately setting the lifter 3, the insert 41 and the wedge block 5 as described above, and adopting a split design for the lifter 3, when the insert 41 is damaged, it is not necessary to remove all the accessory parts. Only after disassembling the lifter head 32 from the lifter body 31, and then pulling out the wedge block 5, the damaged insert 41 can be replaced. The steps are simple, the disassembly is fast and the installation is convenient, greatly shortening the replacement time, thus improving the production efficiency of the product;

[0046] Among them, the lifter 3, the insert 41 and the wedge block 5 are all vertically inserted into the inner mold 2. The wedge block 5 is located between the lifter 3 and the insert 41. The insert 41 is designed with a single-sided opening angle of 3° towards the hollow groove direction; one side of the wedge block 5 away from the insert 41 is set as an inclined surface, which is inclined towards the lifter body 31, and the inclination angle is 1°; the lifter body 31 is a column body arranged obliquely, and the inclination direction is the same as that of the inclined surface of the wedge block 5, and the cross-sectional shape is a parallelogram, and the inclination angle is 2°; the specification of the bolt is M4;

[0047] Specifically, the lengths of the upper and lower end faces of the lifter body 31 are both 16 mm, the widths are both 15.5 mm, and the vertical height of the lifter body 31 is 68.1 mm.

[0048] In one embodiment, the insert group 4 includes a plurality of inserts 41.

[0049] In this embodiment, due to the different fracture frequencies of each section of the strip-shaped insert 41 in the wire groove area, the traditional integral insert body is decomposed into a combination of a plurality of separate inserts 41, and the plurality of inserts 41 are arranged in a straight line along the wire groove area. The purpose of making a plurality of independent inserts 41 is to avoid the waste of mold cost caused by replacing the whole large insert 41 only because a single insert 41 is damaged in a certain local area. When an insert 41 is damaged, only the damaged insert 41 needs to be replaced. Preferably, the number of inserts 41 is 6.

[0050] In one embodiment, a protrusion 42 is provided at the lower end of each insert 41, and a limiting portion 51 is provided at the lower end of the wedge block 5, and the limiting portion 51 is engaged with the protrusion 42.

[0051] In this embodiment, when the insert 41 and the wedge block 5 are simultaneously inserted into the through hole of the inner mold 2, the limiting portion 51 will hold the protrusion 42 to prevent the protrusion 42 from moving, thereby preventing the insert 41 from moving, achieving the function of limiting the insert 41.

[0052] In one embodiment, a thin-walled head 43 is provided at the upper end of the insert 41, and the included angle between the thin-walled head 43 and the insert 41 is set as a round chamfer.

[0053] In this embodiment, in order to eliminate the stress concentration point at the connection between the unnecessary thin-wall head 43 and the insert 41, when designing the insert 41 model, the angle at the connection between the non-sealing side of the thin-wall head 43 and the insert 41 is designed as a round chamfer, so as to enhance the structural strength of the part head feature, improve the durability of the part, and can reduce the fracture frequency of the insert 41 head to a certain extent.

[0054] In one embodiment, a locking ear 52 is provided at the upper end of the wedge block 5, and the locking ear 52 is detachably connected to the inner mold 2.

[0055] In this embodiment, the locking ear 52 and the inner mold 2 are connected by bolts, and the wedge block 5 and the inner mold 2 are fixedly connected by bolts. The purpose is to strengthen the limiting ability of the wedge block 5 and further prevent the insert 41 from shifting during the processing;

[0056] When the locking ear 52 and the inner mold 2 are fixedly connected by bolts, and then the damaged insert 41 is replaced, only the bolts between the locking ear 52 and the inner mold 2 need to be removed, and the wedge block 5 can be pulled out;

[0057] Preferably, the number of the locking ears 52 is 3, and they are arranged alternately with the inclined ejector head 32.

[0058] In one embodiment, a positioning groove 313 is provided on the top surface of the inclined ejector body 31, and a convex platform 322 is provided at the lower end of the inclined ejector head 32, and the convex platform 322 is matched with the positioning groove 313.

[0059] In this embodiment, through the provided mutually matching positioning groove 313 and convex platform 322, when the inclined ejector body 31 and the inclined ejector head 32 are installed and connected, the assembly efficiency and the matching accuracy can be effectively improved, and the time consumption can be reduced;

[0060] In addition, the area of the top surface of the inclined ejector body 31 is limited. When the positioning groove 313 is opened, the side wall of the positioning groove 313 is relatively thin. Therefore, the corners of the inner side wall of the positioning groove 313 are set as round chamfers, and its function is to increase the structural strength.

[0061] In one embodiment, a first reference plane 312 is provided on the upper side wall of the inclined ejector body 31, the first reference plane 312 is perpendicular to the upper end surface of the inclined ejector body 31, a second reference plane 321 is provided on the side wall of the inclined ejector head 32, and the first reference plane 312 and the second reference plane 321 are parallel.

[0062] In this embodiment, the inclined ejector body 31 is an inclined column, and the cross-sectional shape is a parallelogram. When designing the positioning groove 313 of the inclined ejector head 32 on the upper end surface, there is no perpendicular reference plane in one direction for the plane position positioning. An auxiliary reference plane perpendicular to the top surface of the inclined ejector body 31 is designed for machining positioning and data detection.

[0063] In one embodiment, the number of the lifters 3 is two, and the two lifters 3 are arranged side by side.

[0064] In this embodiment, by setting the number of the lifters 3 to two and arranging the two lifters 3 side by side, deformation of the lifters after machining can be prevented; secondly, the machining efficiency and accuracy of the workpiece can be improved, and the assembly difficulty of the lifter assembly can be reduced.

[0065] In one embodiment, the angle at the connection between the bottom surface of the wing plate 33 and the lifter head 32 is set as a rounded chamfer.

[0066] In this embodiment, setting the angle at the connection between the bottom surface of the wing plate 33 and the lifter head 32 as a rounded chamfer also aims to increase the structural strength of the wing plate 33.

[0067] In one embodiment, a ejector rod hanging platform 311 is provided at the lower end of the lifter body 31.

[0068] In this embodiment, by providing the ejector rod hanging platform 311 at the lower end of the lifter body 31, a T-shaped interface is formed between the ejector rod hanging platform 311 and the lower end of the lifter body 31, so that the lower end of the lifter body 31 is buckled with the ejector rod. When replacing the damaged insert 41, it is not necessary to disassemble the lifter body 31 and the ejector rod.

[0069] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
