Description

Technical Field

[0001] This utility model relates to the field of silicone rubber protective sleeve mold technology, specifically a silicone rubber protective sleeve molding mold. Background Technology

[0002] Silicone rubber protective sleeve molds are a type of rapid prototyping tooling specifically designed to manufacture protective sleeves made of silicone rubber. These protective sleeves are commonly used in electronic devices, mechanical parts, and other fields to provide protection such as waterproofing, dustproofing, corrosion protection, shock absorption, and friction reduction.

[0003] Currently, most existing molds still require manual intervention for meticulous trimming after the silicone rubber protective sleeve is formed. This step is not only time-consuming and labor-intensive, increasing production costs, but also depends on the operator's skills and experience, which may lead to inconsistent product quality and affect the final product quality. In view of this, we propose a silicone rubber protective sleeve molding mold. Utility Model Content

[0004] The main objective of this invention is to provide a silicone rubber protective sleeve molding die that can solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model proposes a silicone rubber protective sleeve molding die, including an operating table with a sliding groove. A trapezoidal block, a fixing block, and a rack are fixedly connected to the outer wall of the operating table. A support platform is fixedly connected to the operating table, and a molding device is provided on the support platform. A demolding mechanism is provided on the operating table, and the demolding mechanism includes:

[0006] A mold, wherein a sliding plate is slidably connected to the inner wall of the mold, and a rod is fixedly connected to the outer wall of the sliding plate, the rod penetrating the mold and slidably connected to the mold;

[0007] A pusher plate is slidably connected to the inner wall of a sliding plate, and a rod is fixedly connected to the outer wall of the pusher plate. The rod passes through the sliding plate and the mold and is slidably connected to the sliding plate and the mold.

[0008] A rotating shaft has a limiting groove on its outer wall. The rotating shaft passes through the mold and is rotatably connected to the mold. A gear passes through the lower end of the rotating shaft and is fixedly connected to the gear. A fixing plate is fixedly connected to the upper outer wall of the rotating shaft, and a cutter is fixedly connected to the outer wall of the fixing plate.

[0009] Preferably, a guide rod is fixedly connected to the inner wall of the mold, the guide rod passes through the sliding plate and is slidably connected to the sliding plate, and the sliding plate is elastically connected to the inner wall of the mold by a spring.

[0010] Preferably, a second guide rod is fixedly connected to the inner wall of the sliding plate. The second guide rod passes through the pusher plate and is slidably connected to the pusher plate. The pusher plate is elastically connected to the inner wall of the sliding plate by a spring.

[0011] Preferably, the mold is slidably connected to a limiting rod, the end of which is spherical. The limiting rod is elastically connected to the outer wall of the mold via a spring, and the limiting rod is reset by the elastic force generated by the deformation of the spring.

[0012] Preferably, a threaded block is fixedly connected to the outer wall of the mold, and the threaded block is slidably connected to the slide groove.

[0013] Preferably, the threaded block is penetrated by the lead screw and threadedly connected to the lead screw, and the end of the lead screw is fixedly connected to the motor output end.

[0014] This utility model provides a molding die for a silicone rubber protective sleeve. It has the following beneficial effects:

[0015] (1) The silicone rubber protective sleeve molding die, after the die moves to the designated position, drives the cutter to precisely trim the silicone sleeve through the meshing of gears and racks and the rotation of the shaft. At the same time, the cooperation of the limiting groove and the limiting rod effectively prevents the cutter from deviating during the movement, ensuring the accuracy of the cutting. This design not only improves production efficiency, but also ensures the consistency and stability of product quality.

[0016] (2) The silicone rubber protective sleeve molding die achieves automatic upward movement of the push plate through the contact and extrusion design of the second rod and the fixed block, thereby easily pushing the rubber sleeve out of the sliding plate and completing the demolding operation. No manual demolding is required, which reduces labor costs. Attached Figure Description

[0027] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-7 This utility model proposes a silicone rubber protective sleeve molding die, including an operating table 1, an operating table 1 having a sliding groove 11, a trapezoidal block 12, a fixing block 13 and a rack 14 fixedly connected to the outer wall of the operating table 1, a support table 2 fixedly connected to the operating table 1, a molding device 3 provided on the support table 2, and a demolding mechanism provided on the operating table 1.

[0030] In this embodiment of the invention, in order to perform demolding of the silicone protective sleeve, the demolding mechanism specifically includes a mold 41. A limiting rod 411 is slidably connected to the mold 41. The limiting rod 411 is elastically connected to the outer wall of the mold 41 via a spring. A guide rod 412 is fixedly connected to the inner wall of the mold 41. The guide rod 412 passes through a sliding plate 42 and is slidably connected to the sliding plate 42. The sliding plate 42 is elastically connected to the inner wall of the mold 41 via a spring. The outer wall of the sliding plate 42 is fixedly connected to the mold 41. A first rod 421 is connected, which passes through the mold 41 and is slidably connected to the mold 41. The pusher plate 43 is slidably connected to the inner wall of the sliding plate 42. A second rod 431 is fixedly connected to the outer wall of the pusher plate 43, which passes through the sliding plate 42 and the mold 41 and is slidably connected to both the sliding plate 42 and the mold 41. A second guide rod 422 is fixedly connected to the inner wall of the sliding plate 42, which passes through the pusher plate 43 and is slidably connected to the pusher plate 43. The pusher plate 43 is elastically connected to the inner wall of the sliding plate 42 by a spring.

[0031] Furthermore, a limiting groove 441 is provided on the outer wall of the rotating shaft 44, the rotating shaft 44 passes through the mold 41 and is rotatably connected to the mold 41, the lower end of the rotating shaft 44 passes through the gear 45 and is fixedly connected to the gear 45, and a fixing plate 46 is fixedly connected to the upper outer wall of the rotating shaft 44, and a cutter 47 is fixedly connected to the outer wall of the fixing plate 46.

[0032] Furthermore, a threaded block 17 is fixedly connected to the outer wall of the mold 41. The threaded block 17 is slidably connected to the slide groove 11. The threaded block 17 is penetrated by the lead screw 16 and threadedly connected to the lead screw 16. The end of the lead screw 16 is fixedly connected to the output end of the motor 15.

[0033] In this invention, during use, the raw material is first placed on the outer wall of the sliding plate 42. Then, the motor 15 is started, and through the transmission of the lead screw 16, the threaded block 17 drives the mold 41 to move directly below the pressing device 3. The pressing device 3 is then activated to shape the raw material on the sliding plate 42. After the rubber sleeve cools and solidifies, the motor 15 is started again to return the mold 41 to its original position. Figure 1As shown, during this process, gear 45 meshes with rack 14 first. At this time, shaft 44 drives fixed plate 46 to rotate 90 degrees, so that cutter 47 is directly above sliding plate 42. During the rotation of shaft 44, limiting groove 441 will press against limiting rod 411. It should be noted that there are three sets of limiting grooves 441, and the sum of the included angles of the three sets of limiting grooves 441 is 180 degrees. When shaft 44 rotates 90 degrees, limiting groove 441 will coincide with limiting rod 411. Then, limiting rod 411 will be inserted into limiting groove 441 under the elastic force of spring, thereby limiting cutter 47 and preventing cutter 47 from deviating during movement, thus improving cutting accuracy. Then, rod 421 will contact trapezoidal block 12. At this time, the trapezoidal block 12 will squeeze the first rod 421, causing the sliding plate 42 to move upward. At this time, the rubber sleeve on the sliding plate 42 will be cut by the cutter 47, thus trimming the rubber sleeve. Then, driven by the motor 15, the first rod 421 will disengage from the trapezoidal block 12. At this time, the sliding plate 42 will return to its original position under the action of the spring and gravity. Then, the gear 45 will mesh with the rack 14 again. At this time, the rotating shaft 44 will drive the fixed plate 46 to rotate 90 degrees again. Then, the second rod 431 will contact the fixed block 13. At this time, the fixed block 13 will squeeze the second rod 431, causing the pusher plate 43 to move upward. Through the upward movement of the pusher plate 43, the rubber sleeve is pushed out from the sliding plate 42, thus completing the demolding operation.
