Positioning mechanism for the inner r-angle of the formed product nozzle

Abstract

The invention discloses a displacement mechanism for forming an inner R angle of a nozzle of a molded product, comprising a base, a core-pulling block slidably arranged on the base, and an oil cylinder for driving the core-pulling block to slide on the base. The core pulling block includes a positioning block slidably arranged on the base, and an inclined ejector rod slidably arranged on the positioning block along the sliding direction of the positioning block. The first end of the inclined ejector rod is provided with a fixed seat, and the sliding surface of the fixed seat is provided with a lock pin hole downward, and a lock pin that can slide up and down is provided in the lock pin hole, and a first V-shaped lock pin opposite to the lock pin hole is provided on the base. The bottom surface of the row block is provided with a second V-shaped groove concave upward. The beneficial effect of the present invention is that the overall structure is simpler, no need to use elastic glue to complete the ejection, the ejection action is stable, and the requirement for the inclined ejector rod is low. The inclined ejector rod resets accurately, no need to set the penetration position, and the application range is wider. The service life of the mold is extended. Improve the stability of mold operation.

Description

technical field [0001] The invention relates to the technical field of injection molds, in particular to a positioning mechanism for forming an inner R angle of a nozzle of a product. Background technique [0002] The structure of automotive water chamber products on the market is becoming more and more complex, which brings greater challenges to molds. For example, the R angle inside the nozzle of the automobile water chamber product affects the flow rate of cooling water inside, and the water flow generates noise. If the R angle is not set, the cooling water will not flow smoothly and generate a lot of noise. The products produced in this way will greatly reduce the car owner's experience of the car, which adds considerable difficulty to the structural design of the mold. In the structure of the R angle inside the nozzle of the existing molded product, a simple inclined roof structure is usually adopted. For example, the force of the elastic glue is used to complete the e...

Problems solved by technology

[0003] In view of the problems existing in the prior art, the main purpose of the present invention is to provide a positioning mechanism for the internal R angle of the nozzle of the formed product, aiming at solving the problem of using elastic glue for the positioning mechanism of the internal R angle of the nozzle of the existing molding product. The way to complete the ejection is unstable, demanding, and needs to set the penetration position on the head of the inclined ejector, which has limitations.
