Description

Technical Field

[0001] The utility model belongs to the technical field of mold forming, and in particular relates to a split type spiral insert. Background Art

[0002] The mold is a very important tool in the manufacturing industry, and its quality directly affects the molding quality and production efficiency of the product. In mold manufacturing, when it is necessary to manufacture larger-sized products or complex product structures, it is sometimes necessary to process the mold with inserts. For molds with complex structures, many inserts are usually required. At the same time, the shape of the mold will become more complex as the product structure becomes more complex. Usually, for an integral mold structure, the assembly of the inserts needs to be completed in the cavity, which is sometimes difficult to assemble in place, and it is easy to misplace and difficult to remove, especially for some special structures, such as spiral inserts, which are even more difficult to remove once they are misplaced. At the same time, the processing cost of the integral spiral insert is expensive and the cost is high, which cannot meet the requirements of mass production well. Utility Model Content

[0003] The utility model provides a split spiral insert, which reduces the manufacturing cost and is also convenient for maintenance, disassembly, assembly and later replacement.

[0004] The purpose of the utility model is achieved through the following technical solutions:

[0005] The split spiral insert comprises a spiral rear insert and a spiral front insert which are detachably connected at the head and tail. The spiral front insert is sleeved with a gear set for meshing with a cylinder rack power set.

[0006] Preferably, the rear end of the spiral front insert is sleeved on the front end of the spiral rear insert and are connected via a pin shaft.

[0007] Preferably, a waist-shaped groove is provided on the middle body of the spiral front insert, a waist-shaped convex block is arranged in the waist-shaped groove, and the gear set is placed on the waist-shaped convex block of the middle body of the spiral front insert.

[0008] Preferably, a connecting round pin is also provided between the gear set and the spiral front insert.

[0009] Preferably, a clamp is provided at the front end of the gear set.

[0010] The beneficial effects of the utility model are embodied in that the utility model adopts a split connection structure, which reduces the manufacturing cost of the insert, shortens the manufacturing cycle, facilitates the assembly of the mold, and also facilitates the subsequent disassembly and maintenance, and has strong practicality.

[0015] In order to make the purpose, technical solutions and advantages of the present invention more clear, the following Figure 1-Figure 3 It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0016] The utility model provides a split type spiral insert, comprising a spiral rear insert 1 and a spiral front insert 3 which are detachably connected at the head and tail. The spiral front insert 3 is sleeved with a gear set 2 which is used for meshing with a cylinder rack power set.

[0017] Specifically, the rear end of the spiral front insert 3 is sleeved on the front end of the spiral rear insert 1, the rear end of the spiral front insert 3 is provided with a rear pin hole 31, and the front end of the spiral rear insert 1 is provided with a front pin hole 11, and the two are connected by a pin shaft 4. A waist-shaped groove is provided on the middle body of the spiral front insert 3, and a waist-shaped protrusion 5 is provided in the waist-shaped groove. The gear set 2 is sleeved on the waist-shaped protrusion 5 of the middle body of the spiral front insert 3 through the center hole 21. A round pin hole 22 is provided on the gear set 2, and the round pin hole 22 is further connected to the spiral front insert by a connecting round pin. A clamp 6 is provided at the front end of the gear set 2.

[0018] When in use, the spiral insert is installed in the mold, wherein the rack 9 is meshed with the gear set 2, and the oil cylinder 8 works to drive the rack 9 to reciprocate, which will drive the spiral insert to rotate and reciprocate to achieve the required action in the mold. The mold in this embodiment can have many different forms, and the mold itself does not belong to the protection focus of this utility model, so it will not be described here.

[0019] Finally, it should be noted that the terms "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0020] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
