[0002] For such as Figure 4 For the hose product shown, the existing hose forming mold cannot inject glue in the center because there is a hole in the middle of the product head, and there is an obvious parting line on the product head, which affects the appearance of the product. When the product is easily collapsed and damaged, it will seriously affect the quality of the product

The invention relates to a four-cavity hose forming mold core structure. The four-cavity hose forming mold core structure comprises a glue injection head, a front mold core and a rear mold core, wherein three nozzles arranged in the form of a regular triangle are arranged at an end part of the glue injection head; the front mold core comprises a threaded core, a fixed threaded sleeve and a gear connected with the upper end of the threaded core; the threaded core is in threaded connection with the fixed threaded sleeve; a cavity is located below the threaded core; the rear mold core comprises a plurality of circular ring components and a push sleeve; and the circular ring components are located at the head part of the rear mold core and are used for communicating with an air blowing system. The four-cavity hose forming mold core structure provided by the invention avoids a hole site in the middle of a product, meets the requirement of a head part of the product, and keeps the balance of glue injection; after being formed, the head part of the product is directly rotated to get out of a mold, no parting line is formed, and the product has a more beautiful appearance; when the product is ejected, vacuum is eliminated to reduce a holding force on the product, so that the product can be ejected from the rear mold core more easily and cannot crumple and be damaged easily, and the quality of the product is increased.
Description
technical field [0001] The invention relates to the field of hose forming molds, in particular to a mold core structure of a 4-cavity hose forming mold. Background technique [0002] For such as Figure 4 For the hose product shown, the existing hose forming mold cannot inject glue in the center because there is a hole in the middle of the product head, and there is an obvious parting line on the product head, which affects the appearance of the product. At this time, the product is easy to collapse and damage, which seriously affects the quality of the product. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a core structure of a 4-cavity hose forming mold. [0004] The technical solution adopted by the present invention to solve the technical problem is: a 4-cavity hose forming mold core structure, which includes a glue injection head, a front mold core and a rear mold core; the end of the glue injection ...
