Description

Technical Field

[0001] This utility model relates to the field of extrusion die technology, and in particular to a high-temperature resistant MS sealant layered extrusion die. Background Technology

[0002] In the production of high-temperature resistant MS sealant, layered extrusion places extremely high demands on the stability of the mold and the precision of pressure control.

[0003] Traditional molds lack a reliable fixing structure, and the mounting parts are prone to loosening and displacement during extrusion, resulting in deviation of the sealant extrusion trajectory and uneven layering. Furthermore, since different sealant types exist, a single-size mold cannot achieve the purpose of installing and using sealants of different diameters. At the same time, due to the lack of a precise push control mechanism, it is difficult to stably adjust the extrusion pressure on the sealant, often resulting in inconsistent extrusion volume and uneven pressure, which affects the molding quality and performance stability of the sealant.

[0004] Therefore, those skilled in the art have provided a high-temperature resistant MS sealant layered extrusion mold to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a high-temperature resistant MS sealant layered extrusion mold. The fixing mechanism securely fixes the mounting cover through the engagement of the locking rod and locking groove, as well as the action of the return spring, preventing displacement that could affect extrusion accuracy. It also facilitates disassembly, maintenance, and replacement of mounting covers of different specifications for use with different types of sealants. The driving mechanism drives the extrusion plate with a threaded rod, and works in conjunction with the limiting slide rod to ensure uniform and stable pressure and precise control of the sealant extrusion state. The threaded connection between the drive cover and the fixing cover also facilitates disassembly and assembly. Together, these two mechanisms improve the mold's stability, ease of operation, and sealant extrusion quality.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A high-temperature resistant MS sealant layered extrusion mold includes a fixed cover, an installation cover inside the fixed cover, a hollow limiting head fixedly sleeved on one side of the fixed cover, a fixing mechanism between the fixed cover and the installation cover, and a pushing mechanism on one side of the fixed cover.

[0008] The fixing mechanism includes two fixing columns, which are respectively fixedly sleeved on the upper and lower end faces of the fixing cover. The upper end face of the fixing column has a fixing opening. A fixing ring is fixedly sleeved on the upper part of the inner wall of the fixing opening. A locking rod is movably sleeved inside the fixing ring. A movable ring is fixedly sleeved on the lower part of the outer wall of the locking rod. A return spring is movably sleeved on the outer wall of the locking rod. Both the upper and lower outer walls of the mounting cover have locking grooves. The lower end of the locking rod is locked in the locking groove. A pull head is fixedly connected to the upper end of the locking rod.

[0009] With the above technical solution, by aligning the mounting cover with the fixing cover and inserting it, the locking rod moves downward under the action of the return spring and locks into the locking groove of the mounting cover, thus completing the fixing. When disassembling, pull the pull head upward, the locking rod compresses the return spring and disengages from the locking groove, and the mounting cover can be removed.

[0010] Furthermore, the pushing mechanism includes a limiting plate and a drive cover. Two fixing plates are fixedly sleeved inside the drive cover. Threaded rods are threadedly sleeved inside the two fixing plates. One end of the threaded rod is fixedly connected to a rotating head, and the other end of the threaded rod is rotatably connected to a pressing plate.

[0011] The above technical solution involves rotating the rotating head to drive the threaded rod to rotate within the fixed plate. The threaded rod pushes the extrusion plate towards the sealant, and the extrusion plate applies pressure to the sealant, causing it to be extruded through the hollow limiting head. The thrust of the extrusion plate can be adjusted by controlling the rotation amplitude of the rotating head, thereby controlling the extrusion state of the sealant.

[0012] Furthermore, a limiting slide rod is fixedly connected to the upper and lower parts of one side outer wall of the extrusion plate, and the two limiting slide rods are movably sleeved in the two fixed plates, and the other end of the two limiting slide rods is fixedly connected to a limiting end.

[0013] The above technical solution achieves the purpose of limiting the movement of the extrusion plate by using the limiting slide bar.

[0014] Furthermore, a fixed plate is fixedly sleeved on the outer wall of the drive cover, and a limiting threaded ring is fixedly connected to one side of the fixed plate. The limiting plate is fixedly sleeved on one side of the outer wall of the fixed cover, and an annular threaded groove is opened on one side of the limiting plate. The limiting threaded ring is threadedly sleeved in the annular threaded groove.

[0015] The above technical solution allows for convenient replacement of the drive cover by using a limiting threaded ring threaded into the annular threaded groove.

[0016] Furthermore, limit sliders are fixedly connected to both sides of the movable collar, and limit grooves are formed on the inner walls of both sides of the fixed opening, with the limit sliders slidably disposed within the limit grooves.

[0017] The above technical solution achieves the purpose of limiting the movement of the movable collar by sliding the limiting slider within the limiting groove.

[0018] Furthermore, the two ends of the return spring are respectively fixedly connected to the movable collar and the fixed collar, and the return spring is made of carbon steel.

[0019] By using the above technical solution and limiting the position and material of the return spring, the goal of high-strength use can be achieved.

[0020] Furthermore, the upper and lower ends and one side of the outer wall of the front and rear ends of the mounting cover are all fixedly connected with limit blocks, and the inner wall of the front and rear ends and the upper and lower ends of the fixed cover are all provided with limit slots, and the limit blocks are slidably disposed in the limit slots.

[0021] The above technical solution achieves better restriction by sliding the limiting block within the limiting slot.

[0022] Furthermore, a limiting ring is fixedly connected to one side of the mounting cover, and an annular groove is provided on the inner wall of one side of the fixed cover, with the limiting ring engaging in the annular groove;

[0023] The above technical solution achieves the purpose of stable positioning of the mounting cover by locking the limiting ring in the annular groove.

[0024] This utility model has the following beneficial effects:

[0025] 1. This utility model proposes a high-temperature resistant MS sealant layered extrusion mold. The added fixing mechanism enables a quick and stable connection between the mounting cover and the fixed cover, ensuring the stability of the overall mold structure. Specifically, the mounting cover can be firmly fixed inside the fixed cover by the engagement of the locking rod and the locking groove, preventing the mounting cover from shifting due to vibration during extrusion and ensuring the extrusion accuracy of the sealant. The elasticity of the return spring keeps the locking rod in the locked state, enhancing the reliability of the connection. Pulling the pull head can release the engagement, facilitating the disassembly and replacement of the mounting cover. This makes it easier to maintain the mold or replace mounting covers of different specifications to meet the needs of different sealant types, improving the ease of operation.

[0026] 2. The high-temperature resistant MS sealant layered extrusion mold proposed in this utility model has an added pushing mechanism that can precisely control the extrusion pressure and speed of the sealant, ensuring a uniform and stable layered extrusion effect. That is, rotating the rotating head causes the threaded rod to drive the extrusion plate to move, which can uniformly apply pressure to the sealant and avoid fluctuations in extrusion volume due to uneven pressure. The limiting slide rod restricts the movement direction of the extrusion plate to prevent it from deviating and ensures that the sealant is subjected to uniform force. The drive cover is connected to the annular thread groove of the limiting plate through the limiting threaded ring, which facilitates the disassembly and assembly of the pushing mechanism and the fixed cover, and the connection is firm, avoiding loosening during extrusion and affecting the extrusion accuracy.

[0027] 3. The high-temperature resistant MS sealant layered extrusion mold proposed in this utility model has a fixing mechanism that uses the engagement of the locking rod and the locking groove, along with the action of the return spring, to firmly fix the mounting cover, preventing its displacement from affecting the extrusion accuracy. It also facilitates disassembly, maintenance, and replacement of mounting covers of different specifications, allowing for the assembly and use of different types of sealants. The driving mechanism drives the extrusion plate with the help of the threaded rod, and works in conjunction with the limiting slide rod to ensure uniform and stable pressure, accurately controlling the sealant extrusion state. The threaded connection between the driving cover and the fixing cover also facilitates disassembly and assembly. Together, they improve the mold stability, ease of operation, and sealant extrusion quality. Attached Figure Description

[0039] Reference Figure 1 , Figure 2 , Figure 4 and Figure 6The pushing mechanism 5 includes a limiting plate 503 and a drive cover 501. Two fixing plates 506 are fixedly sleeved inside the drive cover 501. Threaded rods 507 are threadedly sleeved inside the two fixing plates 506. One end of the threaded rod 507 is fixedly connected to a rotating head 508, and the other end is rotatably connected to an extrusion plate 509. Rotating the rotating head 508 causes the threaded rod 507 to rotate within the fixing plate 506, pushing the extrusion plate 509 towards the sealant. The extrusion plate 509 applies pressure to the sealant, causing it to be extruded through the hollow limiting head 3. The thrust of the extrusion plate 509 can be adjusted by controlling the rotation amplitude of the rotating head 508, thereby controlling the sealant extrusion state.

[0040] Working principle: When the device is working, the mounting cover 2 is first installed through the fixing mechanism 4.

Next, the pushing mechanism 5 is installed, and the limiting threaded ring 504 of the driving cover 501 is screwed into the annular threaded groove 505 of the limiting plate 503, so that the pushing mechanism 5 and the fixing cover 1 are fixed. When in operation, rotating the rotating head 508 drives the threaded rod 507 to rotate within the fixed plate 506. The threaded rod 507 pushes the extrusion plate 509 to move. The limiting slide rod 510 slides with the extrusion plate 509 and acts as a guide. The extrusion plate 509 applies pressure to the high-temperature resistant MS sealant inside the mounting cover 2.
