Abstract
The invention provides an insert structure of a product with a concave structure on an inner wall. According to the insert structure, the product with the concave structure on the inner wall can be molded in a mold for one time, so that the precision of the product is improved, and the production efficiency of the product is improved. The insert structure comprises a front mold, a rear mold, a rear mold insert, a plate (A) and a plate (B), wherein a cavity is formed among the front mold, the rear mold and the rear mold insert; the product is arranged in the cavity; the concave structure is arranged on the inner wall of the product. The insert structure is characterized in that a side insert is arranged in the inner wall of the product; the outer ring surface of the side insert is clung to the inner wall of the product; the integrated inclined surface is arranged at the outer tail end of the side insert; the outer integrated inclined surface of the side insert is clamped into an outer T-shaped groove in the inclined surface of a shovel; the side insert specifically comprises an upper front-end insert, an upper rear-end insert, a middle insert and a lower insert.
Description
Technical field
The present invention relates to the technical field of structures of product mold, be specially a kind of insert structure of product of inner wall belt concave inward structure.
Background technology
Existing mould, for the product of inner wall belt concave inward structure, need to be processed concave inward structure by post forming, and because post forming needs secondary location, it makes the low precision of product, and post-forming process makes the production efficiency of product low.
Summary of the invention
The invention provides a kind of insert structure of product of inner wall belt concave inward structure, it makes the product of inner wall belt concave inward structure can one-shot forming in mould, has improved the precision of product, and has promoted the production efficiency of product.
A kind of insert structure of product of inner wall belt concave inward structure, its technical scheme is such: it comprises front mould, rear mold, rear mold mold insert, A plate, B plate, described front mould, rear mold, between rear mold mold insert, form die cavity, in described die cavity, it is product, the inner wall belt concave inward structure of described product, it is characterized in that: in the inwall of described product, be provided with sidepiece mold insert, the outer ring surface of described sidepiece mold insert is close to the inwall of described product, the outside end of described sidepiece mold insert is integral ramp, the outside integral ramp of described sidepiece mold insert is installed in outside the inclined-plane of shovel in T-shaped groove, described sidepiece mold insert specifically comprises top front end mold insert, rear end, top mold insert, middle part mold insert, bottom mold insert, rear end, described top mold insert, middle part mold insert, bottom mold insert three is fastenedly connected, the front end of described middle part mold insert forms the oblique interior T-shaped groove in inner side from top to bottom, the epirelief of top front end mold insert is partly close to described concave inward structure, the lower protruding T-shaped guide rail card of described top front end mold insert is loaded in the T-shaped groove in described inner side, the front end face of described top front end mold insert is close to the lateral surface of described rear mold mold insert, the front end of the T-shaped groove in described inner side is provided with positioning convex.
It is further characterized in that: the bottom of described bottom mold insert is fastened with rest pad, and described rest pad is supported on the upper surface of wear-resistant block, and described wear-resistant block is supported on described B plate.
Adopt after structure of the present invention, because the epirelief of top front end mold insert is partly close to described concave inward structure, the lower protruding T-shaped guide rail card of described top front end mold insert is loaded in the T-shaped groove in described inner side, the front end face of described top front end mold insert is close to the lateral surface of described rear mold mold insert, the front end of the T-shaped groove in described inner side is provided with positioning convex, work as front mould, when A plate rises, drive shovel rises, under the drive of the T-shaped groove in outside, rear end, top mold insert, middle part mold insert, mold insert equal level in bottom moves outwardly, now, in stopping of concave inward structure, from top to bottom under the effect of the oblique interior T-shaped groove in inner side, top front end mold insert moves downward, until the epirelief of top front end mold insert partly departs from concave inward structure, and this at present the front end of protruding T-shaped guide rail touch positioning convex, middle part mold insert drives the demoulding of horizontally outward having moved of top front end mold insert, it makes the product of inner wall belt concave inward structure can one-shot forming in mould, improved the precision of product, and promoted the production efficiency of product.
