A cable extrusion molding die and equipment and production method thereof

Abstract

The invention discloses a cable extrusion-forming mold and device and a cable production method. The cable extrusion-forming mold comprises an inner mold body, a middle mold body and an outer mold body, wherein the inner mold body, the middle mold body and the outer mold body are sequentially arranged in the feeding direction. The inner mold body comprises a fixed mold core and a first nested mold core, wherein the fixed mold core is provided with a conical center cavity and a primary positioning hole part located at the front end of the conical center cavity, and the first nested mold core is nested in the conical center cavity. A first positioning shaft part matched with the primary positioning hole part, a first nested conical part matched with the conical center cavity, and a first nested positioning hole part located in the center are arranged at the front end of the first nested mold core. According to the cable extrusion-forming mold, multiple nested mold cores are nested in the inner mold body, so that the requirement for continuous production of cables of different specifications is met, the halt rate in the production process is decreased, the production efficiency is improved, the manufacturing cost is reduced, and product quality is guaranteed.

Description

technical field [0001] The invention relates to the field of moulds, more specifically to a cable extrusion molding mould, equipment and a production method thereof. Background technique [0002] Cable is an indispensable item in the transmission of information or as a conductor in life. In the existing production technology, every time a cable of a specification is produced, the mold must be stopped and replaced once. Since the extrusion equipment needs to work at a high temperature, every time the mold is replaced, it must be shut down once, and what’s more, the mold must be replaced after the extrusion equipment drops to room temperature, which leads to cumbersome process and more importantly, low efficiency. , high energy consumption. If the production is carried out directly without changing the mold, the large-size cable core will either not pass through and cannot be produced; or the small-size cable core can pass through, but the cable core is eccentric during prod...

Problems solved by technology

Since the extrusion equipment needs to work at a high temperature, every time the mold is replaced, it must be shut down once, and what’s more, the mold must be replaced after the extrusion equipment drops to room temperature, which leads to cumbersome process and more importantly, low efficiency. , high energy consumption

If the production is carried out directly without changing the mold, the large-size cable core will either not pass through and cannot be produced; or the small-size cable core can pass through, but the cable core is eccentric during production, and the produced cable cannot reach to request

These two situations will not only increase the amount of waste products, but also virtually increase the operating costs
