Description

Technical Field

[0001] The invention relates to the technical field of the plastic hollow blow molding industry, and in particular to an automatic cleaning mechanism for die head material accumulation when a blow molding machine injection port moves. Background Art

[0002] The die head of the blow molding machine is a device that discharges the rubber material evenly. When the blow molding machine is working, the rubber material is evenly discharged through the die head, and then squeezed into the mold cavity through two templates. Air is blown into the mold cavity through the blowing unit to shape the rubber material.

[0003] When the die is discharging materials, due to factors such as feeding time and rubber material, material accumulation will occur at the outlet of the die. If the accumulated material is not cleaned up in time, it will cause lumps, holes, depressions and other undesirable conditions on the surface of the blow-molded product. Therefore, when this happens, the die needs to be stopped and cleaned manually.

[0004] In this regard, Chinese patent application No.: 201610748180.0 discloses an automatic material accumulation removal device for an accumulation die head, including an accumulation die head cylinder body, an inner core rod is arranged in the axial direction in the cavity of the accumulation die head cylinder body, a material shooting piston is arranged outside the inner core rod, and a material shooting ring is arranged between the material shooting piston and the inner wall of the accumulation die head cylinder body; a groove connected to the bottom of the material shooting ring is opened in the circumferential direction at the lower position of the inner wall of the accumulation die head cylinder body; and discharge holes connected to the groove are arranged at intervals in the circumferential direction at the position of the outer side wall of the accumulation die head cylinder body located at the groove. The present invention solves the problem of removing accumulated materials, paste, and carbon deposits by arranging grooves on the inner wall of the accumulation die head cylinder body, and then discharging them from the discharge holes after a period of time. It can be used for cleaning accumulation die heads, but it is not suitable for use on blow molding machine die heads.

[0005] Chinese patent application number: 201911055207.8, discloses a wire drawing machine die outlet cleaning device, including a die, a scraper close to the die outlet is provided on one side of the die, and a driving mechanism is provided on one side of the die to drive the scraper to scrape the waste on the die outlet. The present invention has the following advantages and effects: The present invention replaces traditional manual cleaning with mechanical cleaning, reduces labor costs, improves work efficiency and avoids existing safety hazards. The die is cleaned by a scraper, and the material accumulation position of the blow molding machine die is the inner cavity of the inner glue outlet, which cannot be cleaned by parallel scraping of the scraper.
