[0010] In the vehicle audio cover forming mold with demoulding protection as described above, a positioning hole is provided on the fixing protrusion, and a guide column plugged into and matched with the positioning hole is provided on the lower mold core. Before the upper mold core and the lower mold core are separated and the top pressure insert is separated from the lower mold core, the guide column remains plugged into the positioning hole.

[0011] In the above-mentioned vehicle audio cover forming mold with demoulding protection, the limiting portion limits the ejection distance of the top-pressing insert to be smaller than the height of the guide column.

[0012] In the above-mentioned vehicle audio cover forming mold with demoulding protection, the guide column gradually narrows from its lower end to its upper end.

[0013] In the above-mentioned vehicle audio cover forming mold with demoulding protection, the guide columns and the top pressing inserts are arranged in a one-to-one correspondence.

[0014] In the above-mentioned vehicle audio cover forming mold with demoulding protection, the fixing protrusion includes an inner ring protrusion and an outer ring protrusion, and the top pressing insert and the outer ring protrusion together form an enclosed shape.

[0015] The beneficial effects of this application are:

[0016] The utility model provides a vehicle audio cover forming mold with demoulding protection. During demoulding, after the upper mold core and the lower mold core are separated, the movable insert mechanism still keeps contact with the lower mold core for a period of time to stabilize the mesh structure and avoid tearing.

When the upper die core 1 and the lower die core 2 are separated, the top-pressing spring 312 presses the top-pressing insert 311 toward the lower die core 2 to maintain contact. The top-pressing insert remains inserted into the mesh structure and can play a supporting role.

[0028] Further, as a preferred embodiment of the present invention but not limiting, the upper mold core 1 is provided with a limiting portion 11, and the limiting portion 11 is used to limit the ejection distance of the top pressing insert 311. After the top pressing insert is supported, it is driven by the limiting portion to escape from the mesh structure.

[0029] Further, as a preferred implementation of this solution but not a limitation, the two movable insert mechanisms 31 are respectively arranged on two opposite sides of the mesh structure, which can play a good supporting role.

[0030] Furthermore, as a preferred embodiment of the present invention but not a limitation, the core group 3 also includes a fixing protrusion 32 protruding from the upper mold core 1, the fixing protrusion 32 is integrally formed with the upper mold core 1, and together with the top pressing insert 311 forms a mesh structure on the vehicle audio cover.

[0031] Further, as a preferred embodiment of the present solution but not limiting, the fixing protrusion 32 is provided with a positioning hole 33, the lower die core 2 is provided with a guide column 34 plugged into the positioning hole 33, and before the upper die core 1 and the lower die core 2 are separated and the top pressing insert 311 is separated from the lower die core 2, the guide column 34 remains plugged into the positioning hole 33. This can stabilize the position of the upper die core and the lower die core in the mold, and improve the position accuracy of the top pressing insert.

[0032] Further, as a preferred implementation manner of the present solution but not a limitation, the limiting portion 11 limits the ejection distance of the ejection insert 311 to be smaller than the height of the guide column 34 .

[0033] Furthermore, as a preferred implementation of the present solution but not a limitation, the guide column 34 gradually narrows from its lower end to its upper end.

[0034] Further, as a preferred implementation of the present solution but not a limitation, the guide posts 34 are arranged in a one-to-one correspondence with the top pressing inserts 311 .

[0035] Further, as a preferred implementation of the present solution but not a limitation, the fixing protrusion 32 includes an inner ring protrusion 321 and an outer ring protrusion 322 , and the top pressing insert 311 and the outer ring protrusion 322 together form an enclosed shape.

[0036] The above contents are further detailed descriptions of the present invention in combination with specific implementation methods, and it cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention.
