Description

Technical Field

[0001] This utility model relates to the technical field of sanitary material production equipment, specifically to a quick mold change device and a mold. Background Technology

[0002] In the field of sanitary materials, some deep-processed products are produced by mold pressing. When multiple product categories are put into production, a certain mold-changing process will inevitably occur. That is, a production line can use several molds, and different molds are changed according to different product categories (production changeover).

[0003] When changing molds, one approach is to move and position the mold manually, which makes quick and safe mold replacement difficult. Another approach is to use external auxiliary devices for moving and positioning the mold. However, this has drawbacks. Firstly, limited space makes it difficult to install external auxiliary devices. Secondly, the wide variety of mold types makes it difficult to use a single installation method; different molds require different auxiliary installation tools, leading to increased costs and storage space requirements.

[0004] Therefore, how to enable molds to have the functions of quick change and quick positioning has become a technical problem that the industry urgently needs to solve. Utility Model Content

[0005] To address the aforementioned problems, the purpose of this utility model is to provide a quick mold change device and a mold.

[0018] A lifting spring that can be fitted onto a screw.

[0019] As a second aspect, an optional technical solution is that the head size of the screw is larger than the diameter of the through hole.

[0020] Optionally, it also includes a limiting mechanism for axial displacement of the central shaft relative to the chuck.

[0021] Furthermore, the upper end of the central axis extends out of the cup; a plane perpendicular to the central axis is taken as the projection plane, and the upper end of the central axis is projected as a polygon on the projection plane.

[0022] Furthermore, the cup is provided with a central hole extending from the upper end of the central shaft; the central shaft is provided with a stepped surface, the radial dimension of which is greater than the diameter of the central hole; a clamp groove is provided on the outer wall of the central shaft passing through the central hole, and a clamp is installed in the clamp groove.

They are not intended to limit the scope of the invention and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of the invention, should still fall within the scope of the technical content disclosed in this utility model.

[0042] In one embodiment, such as Figures 1-6 As shown, this application proposes a quick-change mold device, which includes a central shaft 101, a chuck 201, and a pull rod. Specifically, a roller 105 is mounted on the lower end of the central shaft 101, and the roller 105 is rotatable relative to the central shaft 101. The central shaft 101 is mounted on the chuck 201, and the central shaft 101 is rotatable around the axis of the chuck 201. That is, the contact surface between the chuck 201 and the central shaft 101 is a cylindrical curved surface. As a preferred embodiment, the contact part between the chuck 201 and the central shaft 101 can be a rotating body. Alternatively, the chuck 201 can directly contact the central shaft 101, or components such as bearings (not shown in the figure) can be installed between them, thereby allowing the chuck 201 to indirectly contact the central shaft 101.

[0043] The cup 201 is provided with multiple ramps 202-1 arranged circumferentially along the rotation axis of the cup 201, and platforms 202-2 connected to the ramps 202-1. The attached figure shows three, but there may also be two, four, five, etc.

[0044] An arc-shaped through hole 203 is provided on the slope 202-1 and the platform 202-2. That is, part of the arc-shaped through hole 203 is on the slope 202-1 and part is on the platform 202-2, and the two parts are connected.

[0045] The pull rod is inserted into the arc-shaped through hole 203, with the upper part of the pull rod protruding from the arc-shaped through hole 203 and the lower part extending out of the arc-shaped through hole 203. Specifically, the upper end of the pull rod protruding from the arc-shaped through hole 203 is provided with a limiting part 301-1. The limiting part 301-1 is located in the arc-shaped limiting part 301-1 to prevent the pull rod from falling out of the arc-shaped through hole 203 when it moves towards the mold 401 (downward in the figure). The lower end of the pull rod protruding from the arc-shaped through hole 301-1 is provided with a connecting part 301-2 for connecting to the mold 401.

[0046] In use, the connecting part 301-2 of the pull rod is connected to the mold 401, and the roller 105 contacts the mounting platform 402. Rotating the chuck 201, guided and lifted by the ramp 202-1, causes the pull rod and mold 401 to move vertically together. For example, when the chuck 201 rotates clockwise... Figure 5 As shown, the pull rod is pushed upwards, at which point the mold 401 can be lifted. The mold 401 does not contact the mounting platform 402; only the roller 105 contacts the mounting platform 402. When the cup 201 rotates counterclockwise, as... Figure 4 As shown, under the action of gravity, the tie rod and mold 401 move downward until they come into contact with the mounting platform 402.

[0047] When mold 401 is lifted, and mold 401 does not contact the mounting platform 402 except for roller 105, pushing mold 401 allows it to move along the mounting platform 402. At this point, due to rolling friction, pushing mold 401 is relatively easy. Simultaneously, rotating the central shaft 101 can cause roller 105 to rotate, achieving a function similar to a caster wheel, allowing mold 401 to move in any direction along the mounting platform 402.

[0048] Along the radial direction of the cup 201, the size of the limiting part 301-1 is larger than the size of the arc-shaped through hole 203, so that the limiting part 301-1 plays a limiting role. On the one hand, it prevents the pull rod from falling off the arc-shaped through hole 203 when it moves towards the mold 401 (downward in the figure). On the other hand, when the mold 401 is lifted, the limiting part 301-1 contacts the cup 201, and the limiting part 301-1 plays a load-bearing role.

[0049] Optionally, the connecting part 301-2 is externally threaded, meaning the pull rod and the mold 401 are connected by a thread. As an optional embodiment, the depth to which the connecting part 301-2 is screwed into the internally threaded hole of the mold 401 is adjustable. This allows the connecting part 301-2 to be screwed downwards into the mold 401 when the slope of the ramp 202-1 is too small, meaning the mold 401 is not raised sufficiently, so the ramp 202-1 can be activated. Conversely, the slope can be adjusted as follows: Figure 6 As shown, the connecting part 301-2 can be rotated upwards appropriately out of the mold 401.

[0050] In another embodiment, such as Figure 7-9 As shown, this application proposes a quick-change mold device, including a central shaft 101, a chuck 201, a screw 302-1, and a lifting spring 302-2. Specifically, a roller 105 is mounted on the lower end of the central shaft 101, and the roller 105 can rotate relative to the central shaft 101. The central shaft 101 is connected to the chuck 201, and the central shaft 101 can rotate around the axis of the chuck 201. That is, the contact surface between the chuck 201 and the central shaft 101 is a cylindrical curved surface. As a preferred embodiment, the contact part between the chuck 201 and the central shaft 101 can be a rotating body. In addition, the chuck 201 can directly contact the central shaft 101, or components such as bearings (not shown in the figure) can be installed between the two, thereby allowing the chuck 201 to indirectly contact the central shaft 101.

[0051] Multiple through holes are provided on the cup 201. The figure shows four through holes, and the axis of the through holes is parallel to the axis of the cup 201. Screws 302-1 are inserted into the through holes. The inner wall of the through holes has no internal threads. The part of screw 302-1 located in the through holes may or may not have external threads.

[0052] The portion of screw 302-1 extending out of the through hole is provided with external threads, which are used to connect to mold 401.

[0053] The lifting spring 302-2 can be sleeved on the screw 302-1. Specifically, when the screw 302-1 is threadedly connected to the mold 401, the lifting spring 302-2 is located between the mold 401 and the cup 201.

[0054] Before moving mold 401, mold 401 is in contact with mounting platform 402. To move mold 401, screw 302-1 is tightened towards mounting platform 402. Lifting spring 302-2 is compressed. As screw 302-1 is tightened, chuck 201 and central shaft 101 continue to move towards mounting platform 402 until roller 105 contacts mounting platform 402, finally lifting mold 401 and separating it from mounting platform 402. At this point, only roller 105 is in contact with mounting platform 402. Since central shaft 101 can rotate relative to chuck 401, the direction of roller 105 can be adjusted by rotating central shaft 401, thus achieving a function similar to a caster wheel, allowing mold 401 to move in any direction along mounting platform 402. Figure 11 As shown.

[0055] When it is necessary for mold 401 to contact mounting platform 402, screw 302-1 is turned in the opposite direction. The cup 201 and central shaft 101 then move away from mounting platform 402 under the action of lifting spring 302-2. Roller 105 also moves away from mounting platform 402, ultimately bringing mold 401 into contact with mounting platform 402. Figure 9 As shown.

[0056] Optionally, the head size of screw 302-1 is larger than the diameter of the through hole. In this case, the head of screw 302-1 can play a limiting role, or it can abut against the cup 201 and move towards the mounting platform 402 when screwed in towards the mounting platform 402.

[0057] Regarding the connection method between the cup 201 and the central shaft 101, it should be noted that a limiting mechanism is also required. The limiting mechanism restricts the axial displacement of the central shaft 101 relative to the cup 201, which is shown in the attached figure as vertical displacement (towards or away from the mounting platform 402).

[0058] Optionally, the upper end 102 of the central shaft extends out of the cup 201, and a plane perpendicular to the axis of the central shaft 101 is taken as the projection plane. The projection of the upper end 102 of the central shaft onto the projection plane is a polygon, such as a hexagon. When it is necessary to rotate the central shaft 101 to turn the roller 105, a wrench or other tool can be used to tighten the central shaft 101.

[0059] Alternatively, a pry bar hole 106 can be provided at the upper end 102 of the central shaft of the protruding cup 201, and this pry bar hole 106 can pass through the upper end 102 of the central shaft. Preferably, the axis of the pry bar hole 106 can be perpendicular to the axis of the central shaft. By inserting a pry bar into the pry bar hole 106, the central shaft 101 can be rotated by the pry bar, thereby turning the roller 105.

[0060] The cup holder 201 has a central hole extending from the upper end 102 of the central shaft. The central shaft 101 has a stepped surface, the radial dimension of which is larger than the diameter of the central hole. For example... Figure 10 As shown, a clamp groove 103-1 is provided on the outer wall of the central shaft 101 passing through the central hole, and a clamp 103 is installed in the clamp groove 103-1. The clamp 103 and the stepped surface restrict the axial displacement of the cup 201 relative to the central shaft 101. In addition, the clamp 103 can also be removed, thereby facilitating the disassembly and assembly of the mold quick change device.

[0061] Regarding the mounting structure of roller 105, such as Figure 10 As shown, the lower part of the central shaft 101 is provided with a roller groove 105-1 and a rotating shaft hole 104-1 communicating with the roller groove 105-1. The roller groove 105-1 is used to accommodate the roller 105, and the roller 105 is rotatably connected to the central shaft 101 through a rotating shaft 104 installed in the rotating shaft hole 104-1. The roller 105 needs to partially protrude from the roller groove 105-1.

[0062] The mounting structure of the roller 105 is not limited to the above-described scheme. Other existing technical solutions that enable the roller 105 to rotate relative to the central shaft 101 are also applicable to this application and will not be described in detail here.

[0063] In one embodiment, this application also proposes a mold, including the aforementioned mold quick-change device, specifically, as follows: Figure 4-6 As shown in Figure 9, the bottom surface of mold 401 is provided with mold hole 403, and mold quick-change device is installed above mold hole 403, with roller 105 corresponding to mold hole 403. It should be noted that the body of mold quick-change device does not protrude from the lower end surface of mold 401; roller 105 can only be adjusted to protrude from the lower end surface of mold 401.

[0064] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
