The utility model discloses a back mould advances to glue, has effectively controlled the volume of mould, has reduced mould cost and maintenance cost, has effectively solved the latticed or the strip structure and has moulded the gluey problem of advancing at a center and the easy defect of moulding plastics that appears, has satisfied the outward appearance requirement of moulding the piece of highlight or electroplating level.
Description
Technical Field
The utility model belongs to the injection mold technique, specific saying so relates to an injection mold's straight top multiple spot advances glued structure.
Background
For plastic parts such as automobile grilles and medium nets, the structure of the plastic parts is usually in a grid shape or a strip shape, when the plastic parts are subjected to injection molding, insufficient filling (full) and occurrence of gathering lines are one of main defects which are easy to occur, the plastic parts are directly scrapped due to insufficient filling (full), the gathering lines influence the strength of the plastic parts and are slightly stressed, the gathering lines are easy to crack, and the plastic parts are used as medium-sized and large-sized plastic parts; if the form of the inverted hot runner is adopted, the structure of the die becomes very complex, the cost of the die is greatly improved, and the market competitiveness of the product is reduced.
Disclosure of Invention
In order to solve the problem, the utility model provides an injection mold's straight top multiple spot advances glued structure, this structure has effectively solved the latticed or strip structure and has moulded the gluey problem of advancing at piece center and the defect of moulding plastics that easily appears.
In order to achieve the purpose, the utility model is realized by the following technical scheme:
the utility model relates to an injection mold's straight top multiple spot advances glued structure, including setting up the straight mold insert in core mould benevolence, core mould benevolence and the top surface of straight mold insert constitute the interior profile of moulding, set up into gluey runner at the lateral wall that core mould benevolence and straight mold insert contacted, the oblique angle of core mould benevolence side runner is greater than oblique apex angle, set up a plurality of runner in advancing gluey runner of straight mold insert, the one end of straight ejector pin is connected in the bottom surface of straight mold insert, the roof is connected to the other end of straight ejector pin, oblique top sets up the lower part at straight mold insert, participate in and constitute local advance gluey runner and the oral cavity of watering a bit, the one end of oblique ejector pin is fixed with oblique top, oblique footstock on the other end of oblique ejector pin and the roof is.
The utility model has the advantages that: the multi-point type direct-ejection glue feeding mechanism has the advantages of ingenious design and simple structure, reliably realizes the glue feeding of the rear mold, effectively controls the volume of the mold, reduces the cost and maintenance cost of the mold, and prolongs the service life of the mold; on the basis of reasonably arranging the multipoint glue inlet, the problem of glue inlet at the center of the plastic part with a latticed or strip-shaped structure and the easy occurrence of injection molding defects are effectively solved, and the appearance quality requirement of a highlight or electroplating grade plastic part is met.
Drawings

Fig. 2 is a schematic structural diagram of the direct-acting insert 1 of the present invention.
Detailed Description
In the following description, for purposes of explanation, numerous implementation details are set forth in order to provide a thorough understanding of the present invention. It should be understood, however, that these implementation details should not be used to limit the invention. That is, in some embodiments of the invention, details of these implementations are not necessary. In addition, some conventional structures and components are shown in simplified schematic form in the drawings.
As shown in fig. 1-2, the utility model relates to an injection mold's straight top multiple spot advances glued structure, including setting up straight top mold insert 1 in core mould benevolence 3, its characterized in that: the mold core insert 3 and the top surface of the straight-top insert 1 form an inner molded surface of a plastic part, a glue inlet flow passage is formed in the side wall of the mold core insert 3 contacted with the straight-top insert 1, the oblique angle of the side flow passage of the mold core insert is larger than the oblique vertex angle, a plurality of point gates are arranged in the glue inlet flow passage of the straight-top insert 1, the bottom surface of the straight-top insert 1 is connected with one end of a straight ejector rod 5, the other end of the straight ejector rod 5 is connected with a top plate, an oblique ejector head 2 is arranged at the lower part of the straight-top insert 1 and participates in forming a local glue inlet flow passage and a point-pouring oral cavity, one end of the oblique ejector rod 4 is fixed with the oblique ejector head 2, and the other end of the oblique.
The utility model utilizes the side wall of the straight top insert contacted with the core insert to provide a glue inlet flow passage, wherein the oblique angle of the core side flow passage is larger than the oblique apex angle; and according to the gridding or strip structure characteristics of the plastic part, a plurality of sprue gates are arranged in the runner of the direct-ejecting insert, so that the back mold glue feeding of the plastic melt is realized, after the mold is opened, the direct-ejecting insert drives the runner and the sprue stub bar to separate from the mold core, and meanwhile, the runner and the sprue stub bar are pushed to separate from the direct-ejecting insert by utilizing the inclined ejection arranged in the direct-ejecting insert.
The above description is only an embodiment of the present invention, and is not intended to limit the present invention. Various modifications and changes may occur to those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the scope of the claims of the present invention.
