Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a novel rapid demolding device for catalytic material molding molds. Background Technology

[0002] During the preparation of catalytic materials, powdered, granular, or paste-like raw materials need to be pressed into specific shapes, such as honeycomb, columnar, or lamellar shapes, using molds to meet the catalytic reaction requirements under different working conditions. Molds are usually divided into upper and lower molds. The upper mold mainly undertakes the function of pressing the raw materials, and its structural design directly affects the molding precision, surface quality, and production efficiency of the catalytic materials.

[0003] In actual production, due to the variety of catalytic materials (such as metal catalysts, ceramic catalysts, polymer catalysts, etc.) and the significant differences in molding process parameters (such as pressure, temperature, pressing speed) and target shape for each material, it is necessary to frequently replace the upper mold assembly to adapt to different production needs.

[0004] Traditionally, the connection between the upper mold and the mold frame or lower mold of a catalytic material molding die is generally achieved by bolt fastening and pin positioning. The bottom of the upper mold has multiple mounting holes, and the corresponding positions of the mold frame or lower mold have threaded holes. Bolts are screwed in to achieve fixation, and positioning pins are used to ensure the relative positional accuracy of the upper and lower molds. Although this installation method can meet the basic connection strength and positioning requirements, in actual applications, each time the upper mold is replaced, multiple bolts need to be removed one by one. The operation is cumbersome and time-consuming. For automated production lines, frequent downtime for mold replacement will lead to production rhythm interruption. Especially in the small-batch, multi-variety production mode, the downtime ratio increases significantly, which seriously affects the production capacity. Utility Model Content

[0005] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a new type of rapid demolding device for catalytic material molding molds. This device can solve the problem that multiple bolts need to be removed one by one each time the upper mold is changed, which is cumbersome and time-consuming. For automated production lines, frequent shutdowns to change molds will lead to interruptions in the production rhythm. Especially in the small batch and multi-variety production mode, the proportion of downtime increases significantly, which seriously affects the production capacity.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a novel rapid demolding device for catalytic material molding molds, comprising a base, a lower mold, a sliding seat, a cylinder, and a top plate, wherein a limit mounting component is provided on the sliding seat;

The two rotating protrusions are rotatably installed inside the corresponding rotating protrusion mounting grooves. Arc-shaped limiting grooves are provided on the left and right outer walls of the upper mold. The two rotating blocks are rotatably installed on the upper surface of the sliding seat. Adjusting threaded rods are threadedly connected to the left and right outer walls of the front end of the sliding seat.

[0008] Among them, the inner wall of the two rotating protrusion mounting slots near the adjusting threaded rod has a slot in which a sliding component is slidably connected. When both sliding components are sliding blocks, the outer wall of the two rotating protrusions is provided with a slider groove. The upper outer wall of the upper mold and the lower surface of the sliding seat are slidably connected inside the slot.

[0010] Preferably, the ends of the two sliders near the slider grooves both extend slidably into the interior of the rotating protrusion mounting groove and are slidably connected to the interior of the corresponding slider grooves.

[0011] Preferably, when the arc-shaped outer walls of the two rotating protrusions contact the inner wall of the arc-shaped limiting groove, the upper mold is mounted on the lower surface of the sliding seat, and the ends of the two rotating blocks near the rotating protrusions extend into the interior of the rotating protrusion mounting groove and are respectively fixedly connected to the upper surface of the corresponding rotating protrusion.

[0012] Preferably, the cylinder is mounted on the upper surface of the top plate, the top plate is fixedly mounted on the base at one end of the four support columns away from the base, and the output end of the cylinder slides to the outside of the top plate and is fixedly connected to the upper surface of the sliding seat.

[0013] Preferably, the four corner slots of the sliding seat are slidably connected to the outer walls of the four support columns on the upper surface of the base. The lower mold is installed inside the slots on the upper surface of the base by bolts. The two sliding rods slidably connected to the upper surface of the top plate extend to the outside of the top plate near the sliding seat and are fixedly connected to the upper surface of the sliding seat.

[0014] Preferably, a sliding plate is slidably connected in a groove inside the lower end of the lower mold, and sliding rods are slidably connected in two grooves on the upper surface of the lower mold. The ends of the two sliding rods near the sliding plate extend slidably into the grooves at the lower end of the lower mold and are fixedly connected to the upper surface of the sliding plate.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. This novel rapid demolding device for catalytic material molding molds uses a limit installation assembly to adjust the threaded rod in the opposite direction, causing the sliding parts to reset and releasing the limit on the rotating protrusion. By rotating the rotating block counterclockwise, the rotating protrusion rotates, causing its arc-shaped surface to disengage from the arc-shaped limit groove of the upper mold and return to a planar contact state. The upper mold can then be directly pulled out from the groove on the lower surface of the sliding seat, completing the disassembly. The entire process requires no additional tools and can be completed with just a simple rotation action, greatly reducing the complexity of operation and effectively reducing production line downtime caused by mold changes. It is especially suitable for the needs of frequent mold changes in small-batch, multi-variety production. Attached Figure Description

[0027] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0028] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] In the description of this utility model, terms such as greater than, less than, and exceeding are understood to exclude the stated number, while terms such as above, below, and within are understood to include the stated number. The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0030] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0031] Example 1: Reference Figure 1-4 A basic example of demolding conventional catalytic materials (sliding block + manually adjustable threaded rod).

[0032] It is suitable for the conventional molding and demolding of common catalytic materials (such as honeycomb ceramics and granular catalysts). The upper mold can be stably installed and easily disassembled through the basic sliding block and manual adjustment structure.

[0033] Structural features: The sliding component adopts a common steel sliding block, which slides in conjunction with the slider groove of the rotating protrusion. The adjusting threaded rod is a manual knob type with anti-slip texture on the surface. The arc-shaped surface of the rotating protrusion is in rigid contact with the arc-shaped limiting groove of the upper mold for positioning.

[0034] Operation and effect: Rotating the adjusting threaded rod drives the sliding part to disengage from the slider groove. Manually rotating the rotating block rotates the rotating convex plane to the horizontal. After the arc surface disengages from the limiting groove, the upper mold can be removed. It is suitable for small and medium-sized molds, with simple structure and low cost, and is suitable for conventional production with a single type of catalyst.

[0035] Example 2: Reference Figure 5 Example of high-load demolding for heavy-duty molds (trapezoidal sliding block + thickened adjusting threaded rod)

[0036] For large-sized, heavy catalyst material molds (such as block catalyst molding molds), the load-bearing capacity is improved by using trapezoidal sliding blocks and reinforced adjustment structures.

[0037] Structural features: The sliding component is replaced with a trapezoidal sliding block. The trapezoidal surface and the trapezoidal sliding groove of the rotating protrusion are wedge-fitted to increase friction. The diameter of the adjusting threaded rod is thickened and high-strength steel is used. A force-saving handle is added to the rotating block.

[0038] Operation and Effects: The wedge action of the trapezoidal sliding block effectively prevents the upper mold from shifting during high-pressure molding. The thickened threaded rod can withstand greater adjustment torque. When demolding, the threaded rod needs to be rotated with a little force, but it can ensure the stable installation of heavy molds.

[0039] Furthermore, when using this device, the rotating block 6 is in a horizontal position, causing the plane of the rotating protrusion 13 to contact the outer wall of the upper mold 9. At this time, the upper mold 9 can slide freely along the groove on the lower surface of the sliding seat 3. Then, the upper end of the upper mold 9 is inserted into the groove on the lower surface of the sliding seat 3, ensuring that the arc-shaped limiting grooves 10 on its left and right outer walls are aligned with the rotating protrusion 13 in the rotating protrusion mounting groove 17. The rotating blocks 6 on both sides are rotated clockwise, causing the rotating protrusion 13 to rotate, so that the arc-shaped surface of the rotating protrusion 13 gradually embeds into the arc of the upper mold 9. The inner wall of the limiting groove 10 forms an arc-shaped surface that fits perfectly, so that the arc-shaped surface of the rotating protrusion 13 is fully engaged with the arc-shaped limiting groove 10. At this time, by rotating the adjusting threaded rod 16, the sliding member 15 (sliding block or trapezoidal sliding block 18) is pushed to slide in the slider groove 14, restricting the reverse rotation of the rotating protrusion 13 and completing the locking of the upper mold 9. The geometric constraint of the arc-shaped surface can simultaneously withstand the vertical pressing force and the lateral force, ensuring no displacement during the pressing process. Then, the cylinder 4 is started, and the output end pushes the sliding seat 3 downward. The sliding seat 3 slides smoothly down along the support column of the base 1 and the sliding rod of the top plate 5, driving the upper mold 9 to insert into the mold cavity of the lower mold 2. At the same time, the upper mold 9 exerts a force on the sliding rod 7, causing it to drive the sliding plate 12 to squeeze the spring 11. Then, the lower punch of the upper mold 9 applies pressure to the catalytic material raw material in the mold cavity. The raw material is formed under high pressure. After pressing is completed, the cylinder 4 first drives the sliding seat 3 to move upward, and the upper mold 9 separates from the formed catalytic material. At this time, the sliding plate 12 in the lower mold 2 is restored by the spring 11. Move upwards, and the ejector pin 8 moves upwards via the sliding rod 7. The top of the ejector pin 8 pushes the molded part out of the cavity of the lower mold 2, completing the demolding. Then, when it is necessary to disassemble the upper mold 9, adjust the threaded rod 16 to rotate in the opposite direction, the sliding part 15 is reset, the limit on the rotating protrusion 13 is released, and the rotating block 6 is rotated counterclockwise, which drives the rotating protrusion 13 to rotate, so that its arc surface is separated from the arc-shaped limiting groove 10 of the upper mold 9 and returns to the plane contact state. Then the upper mold 9 can be directly pulled out from the groove on the lower surface of the sliding seat 3 to complete the disassembly.

[0040] By adjusting the threaded rod 16 in the limiting installation assembly and rotating it in the opposite direction, the sliding part 15 is reset, releasing the limiting of the rotating protrusion 13. Rotating the rotating block 6 counterclockwise causes the rotating protrusion 13 to rotate, causing its arc surface to disengage from the arc-shaped limiting groove 10 of the upper mold 9 and return to the plane contact state. The upper mold 9 can then be directly pulled out from the groove on the lower surface of the sliding seat 3, completing the disassembly. The entire process requires no additional tools and can be completed with just a simple rotation action, greatly reducing the complexity of operation and effectively reducing production line downtime caused by mold changes. It is especially suitable for the needs of frequent mold changes in small-batch, multi-variety production.

[0041] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
