Embodiment Construction

[0033] The technical solutions of the present invention will be further specifically described below through the embodiments and in conjunction with the accompanying drawings.

[0034] see figure 1 , 2 , 3, 4, 5, the composite inclined roof mechanism of this embodiment includes a movable inclined roof insert 1 and an inclined roof body 2, both of which are connected in the form of a trapezoidal groove, in order to ensure that the movable inclined roof insert 1 is on the inclined roof body 2 There is a relative downward movement, and the connection between the two is provided with a slope connection of 10 degrees from the horizontal.

[0035] The inner processing air passage 21 of the inclined top body 2, the air outlet 25 is arranged on the upper end of the inclined top body, and the air inlet 23 is arranged on the lower end side of the inclined top body. During processing, the direction of the inclined top body needs to be changed due to the existence of ports and air passag...

Abstract

The invention relates to an injection mold structure, in particular to an injection mold composite lifter demoulding mechanism, in which barbed demoulding exists in four degree-of-freedom-directions in six degree-of-freedom-spaces on the inner wall of an injection product and which realizes the automatic demoulding function of the product in a mode of composite lifter. The demoulding mechanism comprises an upper mold, a lower mold, a core plate and a travel switch. The lower mold is provided with a movable lifter insert and a lifter body. A runner is arranged between the upper ends of the movable lifter insert and the lifter body and forms a certain angle with the horizontal plane. The lifter body is provided with a lifter guide block in the middle and connected with a lifter sliding seat at the lower end. The composite lifter demoulding mechanism realizes three barbed surfaces on the inner wall of the product, the mold has automatic demoulding function with barbs in the demoulding direction and a cooling water channel as well as a gas-assisted molding air path is arranged on the lifer body.

Description

technical field [0001] The present invention relates to an injection mold structure, in particular to an injection molded product with 6 degrees of freedom space on the inner wall surface, with barbs in 4 degrees of freedom directions for demoulding, and adopting a compound inclined roof to realize the automatic demoulding function of the product Injection mold compound inclined top demoulding mechanism. Background technique [0002] In the general mold structure, the barb on the inner wall of the product is demolded by means of inclined top or inner core pulling. It regards the barb of the product as a part of the inner wall of the product, and there must be more free space to arrange the demoulding mechanism, and the demoulding There are no barbs in the direction of the product, but there are barbs on the three sides of the inner wall of the product, and there are barbs in the demoulding direction, which cannot be realized by the ordinary inclined roof mechanism. The gener...
