A PEEK clamp rubber molding die

Abstract

This utility model discloses a PEEK clamp rubber molding die, including an upper die and a lower die. At least one H-shaped strip is disposed between the upper and lower dies. The H-shaped strip has a molding cavity for accommodating the PEEK clamp. The lower die has a mold core located on one side of the H-shaped strip that mates with the molding cavity. In this utility model, the PEEK clamp is placed into the molding cavity, closing the H-shaped strip unit. The H-shaped strip is positioned by engaging with the positioning protrusion of the lower die through a positioning groove. The upper die moves downwards, guided by its outer inclined surface and the inner inclined surface of the H-shaped strip, completing the mold closing and locking. At this point, the mold core and the molding cavity form a closed cavity. Rubber material is injected into the cavity, pressure and temperature are applied, and maintained for a set time to allow the rubber to vulcanize and crosslink, simultaneously reacting and bonding with the adhesive inside the PEEK clamp. After vulcanization, the mold is opened, the upper die rises, and the H-shaped strip unit is opened, resulting in an integrated PEEK clamp and rubber assembly.

Description

Technical Field

[0001] This utility model relates to the field of clamp preparation technology, specifically a PEEK clamp rubber molding die. Background Technology

[0002] Traditional metal clamps with pads have poor resistance to salt spray (acid), damp heat, and mold, and cannot be used for a long time in the above environments. During installation, the clamp needs to be pried open, clamped with the cable, and then pried back open, which can easily cause the clamp to deform and make it impossible to align the mounting holes. In addition, the rubber pads on the clamps may move or be squeezed to one side during installation, which has a great impact on the installation quality.

[0003] Existing PEEK clamps (such as Figure 6 The technical problem we need to solve is how to mold the rubber pads inside the clamps together. Utility Model Content

[0004] The purpose of this utility model is to provide a PEEK clamp rubber molding die to solve the problems in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a PEEK clamp rubber molding die, comprising an upper die and a lower die, wherein at least one valve strip is provided between the upper die and the lower die, the valve strip having a molding cavity for accommodating the PEEK clamp, and the lower die having a mold core that mates with the molding cavity on one side of the valve strip.

[0006] Preferably, the valve strip has a positioning groove, and the lower mold has a positioning protrusion that cooperates with the positioning groove.

[0007] Preferably, the two sides of the Haval bar are provided with inward inclined surfaces, and the upper mold is provided with an outward inclined surface that cooperates with the inward inclined surfaces.

[0008] Preferably, it also includes a pressure plate, and the upper mold is provided on the side away from the Haver strip.

[0009] Preferably, each of the said Haver strips consists of two unit Haver strips.

[0010] Compared with existing technologies, the advantages of this invention are as follows: The PEEK clamp is placed into the molding cavity, closing the unit's Haver strip (ensuring the PEEK part fits snugly against the inner wall of the molding cavity). The Haver strip engages with the positioning protrusion of the lower mold via a positioning groove to fix its position; the upper mold moves downwards, guided by the outer inclined surface and the inner inclined surface of the Haver strip, completing the mold closing and locking. At this point, the mold core and the molding cavity form a closed cavity. Rubber material is injected into the cavity, pressure and temperature are applied, and maintained for a set time to allow the rubber to vulcanize and crosslink, simultaneously reacting and bonding with the adhesive inside the PEEK clamp. After vulcanization is complete, the mold is opened, the upper mold rises, and the Haver strip unit is opened, resulting in an integrated PEEK clamp and rubber assembly. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0020] Please see Figure 1-6 In this embodiment of the utility model, a PEEK clamp rubber molding die includes an upper die 2 and a lower die 4. At least one valgus strip 3 is provided between the upper die 2 and the lower die 4. A pressure plate 1 is provided on the side of the upper die 2 away from the valgus strip 3. The valgus strip 3 has a molding cavity 31 for accommodating the PEEK clamp. The lower die 4 is provided with a mold core 42 that cooperates with the molding cavity 31 on the side of the valgus strip 3.

[0021] The Haval strip 3 has a positioning groove 33, and the lower mold 4 has a positioning protrusion 41 that cooperates with the positioning groove 33. The positioning groove 33 of the Haval strip and the positioning protrusion 41 of the lower mold cooperate to ensure that the relative position error between the Haval strip and the lower mold is extremely small (≤0.05mm), thus avoiding product size deviation caused by cavity misalignment during mold closing.

[0022] The two sides of the Haval strip 3 are provided with inner inclined surfaces 32, and the upper mold 2 is provided with an outer inclined surface that cooperates with the inner inclined surfaces 32. The inner inclined surfaces 32 on both sides of the Haval strip cooperate with the outer inclined surface of the upper mold. When the mold is closed, it is automatically centered by the inclined surface guide, and at the same time, it fits tightly under pressure to form a wedge locking effect, which greatly reduces the risk of flash (overflow) during rubber vulcanization and improves the appearance quality of the product. Each Haval strip 3 is composed of two unit Haval strips, which can be opened and closed independently, making it easy to put the pre-embedded PEEK clamp (injection molding, inner coating) into the molding cavity, solving the problem of PEEK parts being difficult to load and unload due to shape limitations, and improving the convenience of operation.

[0023] The working principle of this invention is as follows: Prepare injection-molded PEEK clamps (with the inner side pre-coated with rubber-specific adhesive), ensuring the adhesive is surface-dry beforehand. Open the two units of the Haval strip, place the PEEK clamp into the molding cavity 31, and close the Haval strip unit (ensuring the PEEK part fits snugly against the inner wall of the molding cavity). Position the Haval strip by engaging the positioning protrusion 41 of the lower mold via the positioning groove 33; the upper mold 2 descends, guided by the outer inclined surface and the inner inclined surface 32 of the Haval strip, completing the mold closing and locking. At this point, the mold core 42 and the molding cavity 31 form a closed cavity. Inject rubber material into the cavity, apply pressure (typically 10-30 MPa) and temperature (150-180℃), and maintain for a set time (typically 5-30 minutes) to allow the rubber to vulcanize and cross-link, simultaneously reacting and bonding with the adhesive on the inner side of the PEEK clamp. After vulcanization, open the mold, raise the upper mold, open the Haval strip unit, and remove the integrated PEEK clamp and rubber assembly.

[0024] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
