Problems solved by technology

[0004] Therefore, the current mold structure using false ejector pins is relatively cumbersome, and in order to achieve a balanced ejection, multiple ejector pins are generally used in the arrangement, so the cost of the mold is relatively high, and the use of this mechanism will leave ejector pin marks on the appearance of the product. , so it can only be used when there is no requirement for the appearance of the product, so it also has certain limitations

Embodiment Construction

[0014] The present invention will be described in further detail below in conjunction with the accompanying drawings and preferred embodiments:

[0015] Please refer to figure 2 and image 3 , the present invention has a preferred embodiment of the mold of the secondary exit type slider, including a female template 100, a male template 200, a female mold core 101, a male mold core 201, a slider body 10, a slider input Sub 20, an inclined guide post 30, a slider beam block 40, a limit thimble 50, a spring 60, a slider stopper 70, a positioning steel ball 80 and a resistant module 90. The mold of the present invention with a double exit slider is used to produce a product 300 .

[0016] The slider body 10 is arranged in the male template 200, and a groove is arranged in the slider body 10 for placing the slider insert 20, and the slider body 10 and the slider insert 20 can be opposite to each other. Movement, its movement method is similar to the principle of sleeve movement...

Abstract

The invention provides a die possessing a twice exit mode slide block which is used for injection moulding of a product. The die comprises a female template, a male template, a female mold core and a male mold core, the die comprises an inclined guide pillar, a slide block body and a slide block pin. The slide block pin is placed in a groove of the slide block body, and the clearance amount between the slide block body and the inclined guide pillar is larger than the clearance amount between the slide block pin and the inclined guide pillar, the inclined guide pillar drives the slide block pin to move for certain distance when die-opening, thereby the inclined guide pillar is contacted with the slide block body, then the inclined guide pillar drives the slide block body to move for exiting the product. According to the invention, the die possessing twice exit mode slide block forms a twice exit mode through relative movement of the slide block body and the slide block pin. The product has good ejection effect, and the product has no ejector pin mark after being ejected.

Description

【Technical field】 [0001] The invention relates to a mold, in particular to a mold with a secondary retraction slider. 【Background technique】 [0002] When the slider on the mold has deep ribs and the product has no appearance requirements, and the slider has enough space to place ejector pins, a false ejector pin is generally designed in the slider so that when the slider withdraws from the product, it will not be damaged due to The adhesive force of the glue position is too large to stick to the slider and damage the product. [0003] Please refer to figure 1 , the currently used mold includes a female template 1, a male template 2, a female mold core 3, a male mold core 4, a slider body 11, a slider beam block 12, a false thimble 13, and a stopper 14. A slider stopper 15 and a spring 16 . The mold is used to manufacture a product 5 . Wherein, the dummy thimble 13 is a non-standard part, that is, there is no dummy thimble of uniform specification for sale on the market,...
