Description

The inner slide block structure of mould

[technical field]

The utility model relates to a kind of inner slide block structure, is specifically related to a kind of inner slide block structure of mould.

[background technology]

See also Fig. 1, Fig. 1 is a kind of structural representation of product.Product 100 as shown in the figure can have the barb 101 of horizontal direction protrusion and the rib 102 that vertical direction protrudes.For this series products 100, when producing, can't withdraw from after the moulding.

See also Fig. 2, Fig. 2 illustrates a kind of inclined pin structure schematic diagram into prior art.This taper pin 200 is located in the male die core 201, adopts the described product 100 among this taper pin 200 moulding Fig. 1, and a side of this taper pin 200 has the forming surface of the described barb 101 of moulding, and these taper pin 200 tops have the rib forming surface of the described rib 102 of moulding.Yet in the situation that described rib 102 is not cancelled, described taper pin 200 can't withdraw from, so this structure is inadvisable.

See also Fig. 3, Fig. 3 illustrates a kind of inner slide block structure schematic diagram into prior art.The slide block of this inner slide block structure enters son 300 to be located in the male die core 301, and the top of described male die core 301 has the forming surface of the described rib 102 of the described product 100 of moulding, and the side that described slide block enters son 300 has the forming surface of the described barb 101 of moulding.Yet, after described slide block entered son 300 and withdraws from described barb 101, because the stopping of described male die core 301, the barb 101 of described product 100 still can't withdraw from (because described barb 101 protrudes, if what cave in then can withdraw from), so this structure is also inadvisable.

In view of this, be necessary to provide in fact a kind of inner slide block structure of mould, to address the above problem.
