Description

Technical Field

[0001] The utility model belongs to the technical field of fire rubber vulcanization production molds, in particular to a fast model assembly vulcanization mold. Background Art

[0002] The rubber vulcanization mold is an important production equipment in the production of rubber products. Its main function is to provide a closed mold cavity, and to vulcanize and cure the rubber raw materials into rubber products through high temperature and high pressure. The vulcanization mold generally consists of two parts: the template and the cavity mold. The template plays the role of supporting the cavity mold and cooperating with the mold frame of the vulcanizer equipment. At present, the template and the cavity mold are mostly fixed with elastic retaining rings for the shaft or the elastic retaining rings for the hole. The matching structure is complex. Professional disassembly tools are required for the removal of the retaining rings, which is inconvenient to disassemble and install, resulting in a waste of time when disassembling and installing the cavity. At the same time, since the disassembly and assembly of the retaining rings requires a larger space, the interval between the cavity molds on the template is larger and the cavity density is lower. The disassembly and assembly of the template and the cavity mold and the density of the cavity on the template are urgent problems to be solved in improving the production efficiency of vulcanization molds. Utility Model Content

[0003] The purpose of the utility model is to improve the shortcomings of the existing technology and provide a rapid mold loading rubber vulcanization mold, which solves the problem of inconvenient assembly and disassembly of the existing vulcanization mold template and cavity mold and the problem of low density of the mold cavity on the template.

[0004] The technical solution of the utility model is achieved in this way. A quick-assembly model rubber vulcanization mold includes an upper template, a lower template, a cavity upper mold, a cavity lower mold and a positioning device. Its characteristics are that the upper template and the lower template are respectively provided with upper template holes and lower template holes corresponding to each other, the upper template holes are used to install the cavity upper mold, and the lower template holes are used to install the cavity lower mold. Protrusions are arranged at intervals on the outer circumferences of the upper template holes, the lower template holes, the cavity upper mold and the cavity lower mold, and grooves are formed between adjacent protrusions. The protrusions and grooves of the upper template holes and the cavity upper mold, and the lower template holes and the cavity lower mold can be fixed and locked with each other after rotation.

[0005] In order to further achieve the purpose of the utility model, the upper template and the lower template may be provided with four spaced protrusions, and the upper cavity mold and the lower cavity mold may have four spaced protrusions correspondingly, and groove gaps are formed between adjacent protrusions. After the upper template hole and the upper cavity mold, and the lower template hole and the lower cavity mold are assembled respectively, the upper cavity mold and the lower cavity mold are rotated 90 degrees radially, and the upper template hole and the upper cavity mold, and the lower template hole and the lower cavity mold can be quickly locked and fixed respectively.

[0006] To further achieve the object of the present utility model, the positioning device may include a rough positioning device and a precise positioning device. The rough positioning device is that guide columns and guide sleeves are respectively arranged on the upper template and the lower template, and the guide columns and the guide sleeves cooperate to roughly position when the upper and lower templates are closed. The precise positioning device is that circular positioning pin columns and semi-circular positioning pin holes are respectively installed on the upper template and the lower template in the horizontal and vertical directions, and the circular positioning pin columns and the semi-circular positioning pin holes cooperate to precisely position when the upper and lower templates are closed.

[0007] Compared with the prior art, the present utility model has the following remarkable features and positive effects: The present utility model is composed of parts such as an upper template, a lower template, positioning pin columns, guide columns, guide sleeves, bolts, etc. The upper template and the lower template are cooperated through the guide columns and the guide sleeves to achieve preliminary mold closing positioning. The circular positioning pin columns on the upper template and the semi-circular positioning guide pin holes on the lower template, the positioning pin columns and the positioning pin holes are arranged in the horizontal and vertical directions respectively to achieve precise positioning of the mold in two directions; corresponding spaced-apart vulcanization mold cavity upper template holes and lower template holes are provided on the upper and lower templates, and 4 protrusions spaced at 90-degree intervals are respectively provided on the two template holes. Corresponding 4 protrusions spaced at 90-degree intervals are also provided on the upper and lower cavity molds. After installing the cavity mold into the corresponding template holes, rotate it 90 degrees radially to make the protrusions of the cavity mold and the protrusions of the template completely correspond, and then tighten the fixing bolts to complete the installation of the mold. When disassembling the mold, first remove the fixing bolts, and then rotate it 90 degrees radially to stagger and separate the protrusions of the cavity mold and the protrusions of the template holes, and then the mold can be removed, which is convenient and fast. At the same time, the mold of the present utility model has a higher integration degree, and the density of the mold cavities on the template is greatly improved. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation mode

[0014] A rubber vulcanization mold for quickly installing a model, referring to Figure 1 , Figure 2 , Figure 3 , Figure 4 , includes an upper template 1, a lower template 2, an upper cavity mold 3, a lower cavity mold 4 and a positioning device. The upper template 1 is provided with upper template holes 5 at intervals, and the lower template 2 is provided with lower template holes 6 at intervals. The upper template holes 5 are used to install the upper cavity mold 3, and the lower template holes 6 are used to install the lower cavity mold 4. The template holes and the cavity molds are in small clearance fit. The upper template holes 5 and the lower template holes 6 correspond to each other one by one. On the outer circumferences of the upper template holes 5, the lower template holes 6, the upper cavity mold 3 and the lower cavity mold 4, template protrusions 12 and mold protrusions 14 are respectively provided at intervals. Template notches 13 and mold notches 15 are formed between adjacent template protrusions 12 and mold protrusions 14. The positions of the template protrusions 12 and the mold notches 13 on the upper template 1 and the lower template 2 also correspond to each other. After the protrusions and grooves of the upper template holes 5 and the upper cavity mold 3, and the lower template holes 6 and the lower cavity mold 4 are rotated, they can be fixed and locked with each other.

[0015] In this embodiment, the upper template 1 and the lower template 2 are provided with 4 template protrusions 12 arranged at intervals. The upper cavity mold 3 and the lower cavity mold 4 are correspondingly provided with 4 mold protrusions 14 arranged at intervals. Template notches 13 are formed between adjacent template protrusions 12, and mold notches 15 are formed between adjacent mold protrusions 14. After the upper template holes 5 and the upper cavity mold 3, and the lower template holes 6 and the lower cavity mold 4 are respectively assembled, the upper cavity mold 3 and the lower cavity mold 4 are respectively rotated 90 degrees along the radial direction, so that the template protrusions 12 of the template holes and the mold protrusions 14 of the cavity molds are vertically overlapped, and the upper template 1 and the upper cavity mold 3, and the lower template 2 and the lower cavity mold 4 can be quickly locked and fixed respectively. Tighten the fixing bolts of the cavity mold, and the installation of the cavity mold and the template can be completed.

[0016] The positioning device includes a rough positioning device and a precise positioning device. The rough positioning device is that guide posts 8 and guide sleeves 9 are respectively arranged on the upper template 1 and the lower template 2. The guide posts 8 and the guide holes 7 of the upper template, and the guide sleeves 9 and the guide holes 7 of the lower template are in interference fit respectively. The guide posts 8 and the guide sleeves 9 are in clearance fit, and are roughly positioned when the upper template 1 and the lower template 2 are closed. The precise positioning device is that the upper template 1 and the lower template 2 are respectively provided with circular positioning pin posts 10 and semi-circular positioning pin holes 11 in the horizontal and vertical directions. The circular positioning pin posts 10 and the semi-circular positioning pin holes 11 are matched to perform precise positioning when the upper template 1 and the lower template 2 are closed.

[0017] During assembly, align the mold protrusion 14 on the upper mold 3 of the cavity with the template notch 13 inside the template hole 5 of the upper template 1. At this time, the mold notch 15 on the upper mold 3 of the cavity is also in correspondence with the template protrusion 12 inside the template hole 5 of the upper template 1. Vertically insert the upper mold 2 of the cavity into the template hole 5 of the upper template 1, and then rotate it 90 degrees radially to overlap the protrusions of the two. Tighten the cavity fixing bolts to complete the installation of the upper mold 3 of the cavity. Similarly, the lower mold 4 of the cavity is also installed into the lower template hole 6 of the lower template 1. When disassembling the mold, just loosen the cavity fixing bolts, rotate the upper mold 3 of the cavity 90 degrees again to align the mold protrusion 14 on the upper mold 3 of the cavity with the template notch 13 inside the template hole 5 of the upper template 1, and then the upper mold 3 of the cavity can be removed vertically. The disassembly and assembly methods of the lower template 2 and the lower mold 4 of the cavity are the same as above. When the upper and lower templates are closed, the guide pillar 8 and the guide sleeve 9 can roughly align the templates up and down, and the circular positioning pin columns 10 in the horizontal and vertical directions and the semi-circular positioning pin holes 11 can ensure the precise closing of the upper and lower templates.

[0018] The mold structure of the utility model is simple and compact, eliminating components such as snap rings, greatly improving the density of the mold cavity. At the same time, the mold of this structure is convenient for disassembly and installation, without the need for special disassembly tooling, meeting the needs of large-scale and high-efficiency production of rubber products.
