Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a mold with a novel mold core structure. Background Art

[0002] A vulcanization mold is a mold used to process rubber materials. It is mainly used in the vulcanization process in the field of rubber product production. Its application field is very wide. With the continuous development and innovation of rubber technology, the position of vulcanization molds in the production of rubber products is becoming more and more important. At present, vulcanization molds can be mainly divided into vulcanization calendering molds, vulcanization injection molds, vulcanization extrusion molds and other categories.

[0003] Under the existing product design technology, open three-piece bushings are more common. The vulcanization mold designed for the production of such products is characterized by a thin and long core. During the vulcanization production process, the core will be scrapped because it cannot be repaired due to breakage, and the core needs to be replaced for production, which increases production costs. In addition, the process of replacing the core will also consume a lot of time, seriously affecting work efficiency. Utility Model Content

[0004] The utility model aims at the deficiencies of the prior art and provides a mold with a novel mold core structure.

[0005] The utility model solves the above technical problems through the following technical means:

[0006] A mold with a novel mold core structure comprises a mold core body, a jacket and a mold core assembly, wherein the jacket is connected to the top of the mold core body, and the mold core body and the jacket together constitute the main structure of the mold, and the mold core assembly is arranged between the mold core body and the jacket;

[0007] The core assembly includes an insert, a core and a connecting groove. The insert is detachably connected to the core body by screws, the core is fixed on the insert, the connecting groove is arranged on the outer sleeve, and the core is limitedly docked in the connecting groove.

[0008] Preferably, the mold core is made of TOOLOX HRC30-33 new material.

[0009] Preferably, a first middle sleeve is provided on the top of the core body, and circular notches are provided inwardly at both upper and lower ends of the outer sleeve, a second middle sleeve and an inner sleeve are coaxially provided in the notch, and the inner sleeve is located inside the second middle sleeve, and the first middle sleeve is limitedly docked in the gap between the second middle sleeve and the inner sleeve.

[0010] Preferably, a docking hole is provided at the center of the inner sleeve, and a positioning pin is fixed at the top center of the core body, and the positioning pin is clamped in the docking hole.

[0011] Preferably, a limiting groove with an arc-shaped structure is provided on the side wall of the docking hole in an inwardly concave manner, and a protrusion is provided on the outer wall of the positioning pin, and the protrusion is slidably engaged in the limiting groove.

[0012] Preferably, the inner wall of the gap between the outer sleeve and the second middle sleeve is provided with rubber.

[0013] The beneficial effects of the utility model are as follows: compared with the existing core structure, more inserts can be processed and kept in reserve. After the core is broken, only the insert needs to be replaced to continue production, which will greatly reduce maintenance costs and maintenance time, and at the same time can greatly reduce production costs; at the same time, the processing materials are updated, and the new materials also have the advantages of high toughness, bending resistance, and high temperature resistance. The application of new materials will greatly reduce the possibility of core breakage, thereby greatly reducing production costs. By comparing the new and old cores in terms of structure and material, the core structure of the utility model can reduce the possibility of core breakage. At the same time, if the core breaks, the maintenance cost is low and the maintenance time is short, thereby greatly reducing production costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0020] Example

[0021] like Figure 1-Figure 4As shown, in this embodiment, a mold with a novel mold core structure includes a mold core body 1, a jacket 4 and a mold core assembly 10, the jacket 4 is connected to the top of the mold core body 1, and the mold core body 1 and the jacket 4 together constitute the main structure of the mold, and the mold core assembly 10 is arranged between the mold core body 1 and the jacket 4;

[0022] The core assembly 10 includes an insert 101, a core 102 and a connecting groove 103. The insert 101 is detachably connected to the core body 1 by screws, the core 102 is fixed on the insert 101, the connecting groove 103 is arranged on the outer sleeve 4, and the core 102 is limitedly docked in the connecting groove 103. Specifically, when in use, the outer sleeve 4 is docked on the top of the core body 1, and during the docking process, the core 102 and the connecting groove 103 are limitedly docked, so that the core body 1 and the outer sleeve 4 are combined to form the main structure of the mold. After the core 102 is broken, the staff can remove the insert 101 from the core body 1 by screwing the screws, and re-fix the new insert 101 on the core body 1 by screws. The insert 101 can be processed more for backup. After the core 102 is broken, only the insert 101 needs to be replaced to continue production, which will greatly reduce maintenance costs and maintenance time, and can also greatly reduce production costs.

[0023] like Figure 1-Figure 4 As shown, in some embodiments, the mold core 102 is made of a new material of TOOLOX HRC30~33. By replacing the traditional material with the new material, the mold core 102 has the advantages of stable performance, good corrosion resistance, nitriding, good forgeability, etc., and at the same time has the advantages of high toughness, bending resistance, high temperature resistance, etc. The application of the new material will greatly reduce the possibility of the mold core 102 breaking, thereby greatly reducing the production cost.

[0024] like Figure 1-Figure 4 As shown, in some embodiments, a first middle sleeve 3 is provided on the top of the core body 1, and circular notches are provided at the upper and lower ends of the outer sleeve 4 in an inwardly concave manner. A second middle sleeve 5 and an inner sleeve 6 are coaxially provided in the notch, and the inner sleeve 6 is located inside the second middle sleeve 5. The first middle sleeve 3 is limitedly docked in the gap between the second middle sleeve 5 and the inner sleeve 6. The concave-convex structure formed by the notch docking enables the connection between the core body 1 and the outer sleeve 4 to form a sealing structure, thereby improving the sealing performance.

[0025] like Figure 1-Figure 4 As shown, in some embodiments, a docking hole 8 is provided at the center of the inner sleeve 6, and a positioning pin 2 is fixed at the top center of the core body 1, and the positioning pin 2 is clamped in the docking hole 8. The outer sleeve 4 is positioned by the positioning pin 2 so that the outer sleeve 4 can be quickly docked on the core body 1.

[0026] like Figure 1-Figure 3As shown, in some embodiments, a limiting groove 9 with an arc-shaped structure is concavely provided on the side wall of the docking hole 8, a protrusion is provided on the outer wall of the positioning pin 2, and the protrusion is slidably engaged in the limiting groove 9, and the outer sleeve 4 is limited by the protrusion to prevent the outer sleeve 4 from rotating on the core body 1 and causing the insert 101 to break.

[0027] like Figure 1-Figure 3 As shown, in some embodiments, rubber 7 is provided on the inner wall of the gap between the outer sleeve 4 and the second middle sleeve 5 to further improve the sealing between the mold core body 1 and the outer sleeve 4 .

[0028] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
