CONCRETE IMPLEMENTATION

[0018] The utility model will be further described in connection with the drawings:

[0019] A slider positioning structure of mould, the slider 1 of mould can slide on wear -resistant board 2, and wear -resistant board 2 is equipped with wear -resistant board fixed hole 3 with the fixed mould, the bottom of slider 1 is equipped with locating hole 4, and the locating hole 4 is V -shaped recess;Elastic positioner 5 passes through wear -resistant board 2 and can be inserted into the locating hole 4, and the elastic positioner 5 includes elastic member 6, the top of elastic member 6 is equipped with locating post 7, and the top of locating post 7 is ∧ -shaped, and locating step 8 is further equipped on the locating post 7. The utility model discloses a through the elastic positioner 5 of wear -resistant board, and the elastic positioner 5 includes elastic member 6, the top of elastic member 6 is equipped with locating post 7, and the locating hole 4 of V -shaped recess is processed to the bottom of slider. After injection molding is completed, slider 1 retreats to the stroke position when opening mould, and elastic positioner 5 is under the action of elastic member 6 and pops up and clamps slider 1, and slider 1 stops movement, thereby realizing slider positioning.

[0020] The top of locating post 7 of the utility model is arc 71, so that locating post 7 is more smooth when being inserted into locating hole 4, and will not be stuck. The locating hole 4 is preferably also equipped with smooth transition inclined surface, to facilitate locating post 7 to exit locating hole 4.

[0021] The wear plate 2 is provided with a wear plate hole 9 through which the elastic positioner 5 passes, the upper part of the positioning column 7 is a rectangle, and the wear plate hole 9 is also a rectangle hole. The lower part of the positioning column 7 is a cylinder, and the elastic member 6 is a cylindrical spring. The limiting step 8 is arranged between the upper part and the lower part of the positioning column 7, and the limiting step 8 functions to limit the positioning column 7 from completely passing through the wear plate 2 and to limit the stroke of the positioning column 7 from being pushed out upward.

[0022] The elastic positioner 5 is a pair, and the pair of elastic positioners are arranged side by side; the positioning hole 4 is also a pair, and the pair of positioning holes are arranged side by side and correspond to the pair of elastic positioners.

[0023] The upper surface of the wear plate is provided with a wear-resistant layer, and the lower surface of the sliding block is also provided with a wear-resistant layer. The thickness of the two wear-resistant layers is in the range of 3mm to 30mm, and the wear-resistant layer can be made of tool steel, hard alloy, ceramic, steel, graphite. The most preferred is hard alloy, which is made of refractory metal carbide such as tungsten carbide and titanium carbide and metal binder such as cobalt and nickel by powder metallurgy method, has very high hardness and wear resistance, can withstand high temperature and high pressure environment, and is very suitable for manufacturing wear plate of injection mold.
