Detailed Description

Embodiments of the present utility model will be further described with reference to fig. 1 to 7.

The utility model discloses a die for producing a surge protector shell, which comprises an upper fixing plate 1, an upper die plate 2, a lower die plate 3, die legs 4 and a lower fixing plate which are arranged from top to bottom, wherein a shell cover cavity 20 and a shell cavity 21 are arranged at the bottom of the upper die plate 2, a shell cover core 30 matched with the shell cover cavity 20 and a shell core 31 matched with the shell cavity 21 are arranged on the lower die plate 3, a sprue bush 10 is arranged on the upper fixing plate 1, a straight slot 22 communicated with the shell cover cavity 20 and the shell cavity 21 is penetratingly formed in the upper die plate 2, a guide plate 6 is fixed in the straight slot 22, feeding holes 60 communicated with the shell cover cavity 20 and the shell cavity 21 are respectively formed at two ends of the guide plate 6, a runner 11 arranged along the guide plate 6 is arranged at the bottom of the upper fixing plate 1, feeding holes 60 at two ends of the guide plate 6 are respectively communicated with two ends of the runner 11, the sprue bush 10 is arranged at the center of the runner 11 and is communicated with the runner 11.

Further, a U-shaped groove 23 is formed on one side of the upper mold plate 2, which is close to the upper fixing plate 1, along the circumference of the guide plate 6, a stub bar top block 7 capable of sliding up and down is arranged in the U-shaped groove 23, and branch runners 110 extending to above the stub bar top block 7 are respectively arranged on two sides of the split runner 11 corresponding to the two feeding holes 60 and the sprue bush 10.

Further, guide sleeves 8 positioned at four corners of the jacking block are respectively arranged on the upper fixing plate 1, connecting bolts 9 which are in up-down sliding fit are respectively arranged in the guide sleeves 8, the connecting ends of the connecting bolts 9 penetrate through the upper fixing plate 1 and are fixed on the jacking block in a threaded fit manner, and limiting rings 80 which are arranged at the bottoms of the inner cavities of the guide sleeves 8 in an abutting fit manner with the end parts of the connecting bolts 9 are arranged at the bottoms of the inner cavities of the guide sleeves.

Working principle: the utility model discloses a mould is when producing surge protector casing, owing to be provided with cap die cavity 20 and casing die cavity 21 in arranging at cope match-plate pattern 2 bottom arrange on the lower bolster 3 be provided with cap die cavity 20 cooperation setting's cap core 30 to and the casing core 31 that the cooperation of casing die cavity 21 set up, sprue bush 10's sprue feeding when production, and get into cap die cavity 20 and casing die cavity 21 through shunt 11, realize once die sinking just can produce casing and cap, need not carry out the die sinking alone with casing and cap, great reduction the manufacturing cost of enterprise.

In addition, the upper fixed plate 1 can separate the upper template 2 when the drawing of patterns, the stub bar in the shunt 11 can be located on the guide plate 6 at this moment, when the upper fixed gradually keeps away from the upper template 2, connecting bolt 9 that is located in guide sleeve 8 just can form the conflict with spacing ring 80, when connecting bolt 9 supports on spacing ring 80, it just can drive stub bar kickup 7 separation cope match-plate pattern 2 through connecting bolt 9 to go up to fix in the separation process, stub bar kickup 7 just can drive the stub bar of branch runner 110 department and break away from guide plate 6 this moment, further just can drive whole stub bar and drop, realize that the stub bar is full-automatic to drop, do not need mechanical intervention to get the stub bar, thereby shorten the shaping cycle.

In addition, as shown in fig. 7, it can be seen that the separation surface between the shell cavity 20 and the shell core 30, and the separation surface between the shell cavity 21 and the shell core 31 are the surfaces of the shell and the shell cover that are mutually buckled and spliced, so that the outer surfaces of the shell and the shell cover can be smooth and seamless, and the appearance can be more attractive.
