And gaps which are not smaller than 1mm are formed between the peripheral outer side walls of the multi-version female die and the corresponding inner side walls of the mounting grooves.
The positioning block is cylindrical and is provided with an arc head corresponding to one end of the multi-version insert, so that the positioning block is clamped into the second positioning groove of the multi-version insert.
Through the technical scheme, the multi-version female die quick die change structure provided by the utility model shortens the die change time, the required version can be directly changed on the machine table, the insert is changed once probably within 6 hours, at present, only 1 hour is needed, one version is saved for 5 hours, and 10 versions are 50 hours.
Drawings
In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the drawings used in the description of the embodiments will be briefly introduced below.
Fig. 1 is a schematic sectional structure view of an injection mold disclosed in an embodiment of the present invention.
In the figure: 10. a lower die holder; 20. a lower push plate; 30. a lower base plate; 40. a master template; 41. positioning blocks; 42. a multi-version insert; 43. a multi-version master mold; 44. fixing screws; 45. a hot runner valve needle; 46. and (7) installing the block.
Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
Referring to fig. 1, the multi-version master mold injection mold capable of rapidly changing molds provided by the utility model comprises an upper mold and a lower mold; the lower die comprises a lower die base 10, a lower push plate 20, a lower backing plate 30 and a mother die plate 40 which are arranged in sequence, and a hot runner valve needle 45 is arranged in the mother die plate 40 through a mounting block 46; the upper surface of the female die plate 40 is provided with a mounting groove, the bottom of the mounting groove is provided with a plurality of first positioning grooves, and cylindrical positioning blocks 41 are arranged in the first positioning grooves; a multi-version insert 42 with a second positioning groove at the bottom is installed in the installation groove, one end of the positioning block 41 corresponding to the multi-version insert 42 is provided with an arc head and is correspondingly clamped into the second positioning groove of the multi-version insert 42, and the multi-version insert 42 is provided with a first position avoiding hole corresponding to the hot runner valve needle 45; a multi-version female die 43 is further installed in the installation groove, gaps which are not smaller than 1mm are formed between the outer side walls of the periphery of the multi-version female die 43 and the corresponding inner side walls of the installation groove, a groove corresponding to the multi-version insert 42 is formed in the bottom of the multi-version female die 43, the multi-version insert 42 is clamped in the groove, and the multi-version female die 43 is provided with a second avoiding hole corresponding to the hot runner valve needle 45; the hot runner valve needle 45 sequentially penetrates through the female template 40, the multi-version insert 42 and the multi-version female mold 43 and corresponds to a mold cavity formed between the multi-version female mold 43 and the male template of the upper mold; the multi-version female die 43 is locked in the mounting groove of the female die plate 40 by a fixing screw 44.
