Injection mold for embedding of automobile sealing strip insert

Abstract

The invention discloses an injection mold for embedding of an automobile sealing strip insert. The injection mold comprises an upper mold plate (1), a lower mold plate (2), an ejection plate (3), a base plate (4) and a sealing strip (7). The ejection plate (3) is located on the base plate (4). The lower mold plate (2) is located between the upper mold plate (1) and the ejection plate (3). An upper mold plate (5) is arranged below the upper mold plate (1). A lower mold plate (6) is arranged above the lower mold plate (2). The lower mold plate (2) is provided with an oblique slide block (8) used for forming the rubber coating part of the front end face of the sealing strip (7), a slide block (22) used for forming the rubber coating part of the inner side face of the sealing strip (7) and a mobile slide block (36) positioning the outer side face of the front end of the sealing strip (7). The upper mold plate (1) is provided with an oblique guide column (33) slidably matched with the oblique slide block (8). By adoption of the injection mold for embedding of the automobile sealing strip insert, personal injury cannot be caused, so that the safety coefficient is high.

Description

technical field [0001] The invention relates to the technical field of moulds, in particular to an injection mold for built-in automotive sealing strip inserts. Background technique [0002] Automobile sealing strip is one of the important parts of automobiles. It is widely used in doors, windows, body, seats, sunroof, engine box and trunk, etc. It has waterproof, sealing, sound insulation, dustproof, antifreeze, shock absorption, The important role of heat preservation and energy saving. The water-cut strip is the rubber sealing strip inside the window groove, which is between the window glass and the door frame. The front part of the water-cut strip needs to be glued on the injection molding machine. In order to ensure that the injection molding head and Body fixed fit requires built-in inserts in the product. Generally, the fixed inserts are first placed in the mold for fixing, and then the semi-finished product is placed on the mold, and then the mold is closed and enca...

Problems solved by technology

Such operation methods lead to low production efficiency, low pass rate, easy crushing of molds, and the safety of employees cannot be guaranteed.

At the same time, due to the spring reset and the gravity of the template, the lower formwork is easy to fall off before it is placed, so that hands will be caught during the placement of the sealing strip, which will cause personal injury and low safety factor
