Description

Technical Field

[0001] The utility model relates to the technical field of mold application, in particular to a positioning ring structure for positive and negative uses. Background Art

[0002] During the injection molding process, the nozzle of the injection molding machine needs to match the positioning ring of the mold, and the positioning ring needs to be adapted to the diameter of the nozzle to ensure the stability of the injection molding process and avoid the displacement of the mold, thus affecting the quality of production. In addition, because the injection molding machine came first, and the conventional injection molding machine nozzle diameter has two models of 100 and 120, and then the mold, so in the process of mold development, generally only a fixed size positioning ring is designed, corresponding to a fixed model of injection molding machine, but sometimes according to the actual production situation, when another model of injection molding machine needs to be replaced for production, in the past, it was generally only possible to wait for the corresponding machine to be vacant before injection molding production. Therefore, before each injection molding production, the planner needs to master the relevant dimensions of the mold and find a matching machine for production scheduling. However, it has certain disadvantages:

[0003] First, the relevant dimensions and performance of the mold need to be mastered every time production is carried out, which increases the work content of the planner and the management cost;

[0004] Secondly, if you need to change the injection molding machine, you need to purchase additional positioning rings to match the relevant injection molding machine. The old positioning rings that have been removed need to be classified and kept in time to avoid loss.

[0005] Third, when making the mold, sometimes it is necessary to consider purchasing spare positioning rings, and two states need to be made, which significantly doubles the material cost and processing cost;

[0006] Finally, each removal and installation of the locating ring will cause wear and tear on the mold, which will increase the risk of mold damage over time.

[0007] Therefore, the utility model proposes a positioning ring structure that can be used both positively and negatively. Utility Model Content

[0008] The technical problem to be solved by the utility model is to provide a reversible positioning ring structure, which has a simple structure, is more convenient and reliable to use, is easy to store and will not be lost. Each mold only needs one reversible positioning ring, which can quickly solve the problem of switching production of the injection molding machine during injection molding production.

[0009] In order to solve the above technical problems, a technical solution adopted by the utility model is: to provide a positioning ring structure with both positive and negative uses, including a fixed mold plate, a positioning plate is bolted to the top center of the fixed mold plate, a first convex ring is provided on one side of the positioning plate, and a second convex ring is provided on the other side of the positioning plate, and the positioning plate is screwed to the top of the fixed mold plate by a sinker screw set through it.

[0010] The utility model is further configured as follows: mounting holes are provided on the top of the fixed mold composite plate near the corners.

[0011] The above technical solution makes it easy to install and fix the fixed mold plate in position, and facilitates overall installation and replacement.

[0012] The utility model is further configured as follows: a through hole is opened at the top center of the fixed mold composite plate, a positioning groove is opened at the top of the through hole, the positioning plate is embedded in the positioning groove, and a plurality of positioning holes are radially distributed at the top of the positioning groove.

[0013] The above technical solution facilitates rapid processing of the through hole when processing the entire positioning plate, and uses the positioning groove to facilitate embedding the positioning plate to be installed externally, and uses the sinker screw to fix it on the positioning hole.

[0014] The utility model is further configured as follows: the positioning plate is symmetrically provided with a first sinking hole located near the outer wall on one side of the first convex ring, and the end faces of the two sinking screws respectively pass through the first sinking hole and are threadedly connected to the corresponding positioning holes.

[0015] Through the above technical solution, it is convenient to use two sinker screws to lock and fix the positioning plate installed in the positioning groove, so that the first convex ring is placed on the top of the positioning plate and connected to the corresponding external nozzle for use.

[0016] The utility model is further configured as follows: the positioning plate is symmetrically provided with second countersunk holes at a position close to the outer wall and away from the two first countersunk holes on one side of the second convex ring, and the end faces of the two countersunk screws respectively pass through the second countersunk holes and are threadedly connected to the corresponding positioning holes.

[0017] Through the above technical solution, it is convenient to use two sinker screws to lock and fix the positioning plate installed in the positioning groove, so that the second convex ring is placed on the top of the positioning plate and connected to the corresponding external nozzle for use.

[0018] The utility model is further configured as follows: the outer arc diameter of the first convex ring is 100 mm.

[0019] The above technical solution facilitates the installation and use of the first convex ring and the injection nozzle with an external diameter of 100 mm.

[0020] The utility model is further configured as follows: the outer arc diameter of the second convex ring is 120 mm.

[0021] The above technical solution makes it easy to install and use the second convex ring and the injection nozzle with an external diameter of 120 mm.

[0022] The utility model is further configured as follows: the first convex ring and the second convex ring are located on both sides of the positioning plate, and the centers of the circles are symmetrically arranged, and the inner diameters are equal.

[0023] The above technical solution facilitates the manufacturing and processing of the first convex ring and the second convex ring, and facilitates direct milling and removal of the inner hole, thereby improving the processing efficiency of the entire structure.

[0024] The beneficial effects of the utility model are as follows:

[0025] The biggest feature of the positive and negative dual-purpose positioning ring structure proposed by the utility model is that the structure is simple, easy to install, easy to disassemble, simple to operate, easy to store, saves production costs, shortens the production waiting period, and keeps the on-site environment clean and tidy, reducing the on-site workload of the injection molding machine operator.
