Description

Technical Field

[0001] This utility model relates to the field of mold manufacturing technology, and in particular to a quick clamping device for mold production. Background Technology

[0002] Molds mainly refer to various molds and tools used in industrial production to obtain desired products through methods such as injection molding, blow molding, extrusion, die casting, forging, smelting, and stamping. In short, a mold is a tool used to shape objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly achieves the processing of the object's shape by changing the physical state of the material being molded.

[0003] Existing clamps primarily rely on the traditional method of manually tightening bolts to hold and fix mold plates. Operators need to manually turn the bolts round and round to gradually tighten the mold plates. This manual bolt tightening method cannot achieve quick and convenient clamping operations. In actual production scenarios, each mold clamping requires a lot of time and effort from the operator. The operator needs to repeatedly perform the manual tightening action until the bolts are sufficiently tight. This process is not only monotonous and tedious, but also inefficient.

[0004] Therefore, there is an urgent need to provide a quick clamping device for mold production to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a quick clamping device for mold production.

[0008] The present invention is further configured such that: a placement groove is provided inside the base, multiple sliding grooves are provided on both sides of the placement groove, symmetrical slots are provided inside the base, and rotating grooves are provided on both sides of the base.

[0009] Through the above technical solution, the placement groove is used for placing and clamping the mold, the sliding groove cooperates with the protrusions on both sides of the support plate to make the support plate more stable when moving up and down inside the placement groove, the slot cooperates with the insert block to make the clamping head stable inside the placement groove after clamping the mold, and the rotating groove provides space for the rotation of the rotating rod.

[0010] The present invention is further configured such that: a first spring is fixedly installed on the lower surface of the support plate, the other end of the first spring is fixedly connected to the inside of the placement groove, a plurality of protrusions are fixedly installed on both sides of the support plate, the protrusions are slidably connected inside the sliding groove, and symmetrical inserts are fixedly installed on the lower surface of the support plate, the inserts being movably inserted into the slot.

[0011] Through the above technical solution, by setting the first spring, after the mold on the surface of the support plate is removed, the support plate can return to its initial position and wait for the next use. The protrusion slides inside the slide groove and squeezes the end of the support, thereby causing the rotating rod to rotate and push the chuck to clamp the two sides of the mold.

[0012] The present invention is further configured such that: the clamping mechanism includes a rotating rod, the rotating rod is rotatably connected inside the rotating groove, the rotating rod is rotatably connected inside the base, an upper bracket is fixedly installed on the surface of the rotating rod, a push rod is hinged to the end of the upper bracket, a chuck is fixedly installed at the end of the push rod, and the chuck is slidably connected inside the placement groove.

[0013] With the above technical solution, when the bearing plate moves down inside the placement groove, the protrusion squeezes the end of the lower support, so that the rotating rod can rotate. The upper support rotates and pushes the push rod to move. The clamp at the end of the push rod contacts the mold surface and quickly clamps the mold.

[0014] The present invention is further configured such that: a lower bracket is fixedly installed on the surface of the rotating rod, the end of the lower bracket is movably fitted with the lower surface of the bearing plate, a rotating shaft is fixedly installed inside the rotating rod, both ends of the rotating shaft are fixedly connected to the inner wall of the rotating groove, a torsion spring is fixedly connected to both ends of the rotating rod, the other end of the torsion spring is fixedly connected to the inner wall of the rotating groove, and the rotating shaft passes through the inside of the torsion spring.

[0015] Through the above technical solution, by setting up the rotating shaft and torsion spring, when the mold is removed from the surface of the support plate, the support plate can be moved to the initial position under the restoring action of the first spring and the torsion spring to wait for the next use.

[0027] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0028] Please see Figures 1-4 This application provides a quick clamping device for mold production, including a base 1, and a support plate 2 for placing molds is slidably connected inside the base 1.

[0029] like Figure 2 As shown, the base 1 has a placement groove 11 inside, multiple sliding grooves 12 on both sides of the placement groove 11, symmetrical slots 13 inside the base 1, and rotating grooves 14 on both sides of the base 1.

[0030] In this embodiment: the placement groove 11 is used for placing and clamping the mold, the slide groove 12 cooperates with the protrusions 22 on both sides of the support plate 2 to make the support plate 2 more stable when moving up and down inside the placement groove 11, the slot 13 cooperates with the insert block 23 to make the clamp 34 stable inside the placement groove 11 after clamping the mold, and the rotation groove 14 provides space for the rotation of the rotating rod 31.

[0031] like Figure 3 As shown, a first spring 21 is fixedly installed on the lower surface of the support plate 2, and the other end of the first spring 21 is fixedly connected to the inside of the placement groove 11. Multiple protrusions 22 are fixedly installed on both sides of the support plate 2, and the protrusions 22 are slidably connected inside the slide groove 12. Symmetrical inserts 23 are fixedly installed on the lower surface of the support plate 2, and the inserts 23 are movably inserted into the slot 13.

[0032] In this embodiment: by setting the first spring 21, after the mold on the surface of the support plate 2 is removed, the support plate 2 can return to the initial position and wait for the next use. The protrusion 22 slides inside the slide groove 12 and presses the end of the support 35, thereby causing the rotating rod 31 to rotate and push the clamp 34 to clamp the two sides of the mold.

[0033] The base 1 has a clamping mechanism 3 for clamping the mold and a snap-fit ​​mechanism 4 for fixing the sliding of the bearing plate 2.

[0034] like Figure 2 As shown, the clamping mechanism 3 includes a rotating rod 31, which is rotatably connected inside the rotating groove 14 and the base 1. An upper bracket 32 ​​is fixedly installed on the surface of the rotating rod 31. A push rod 33 is hinged to the end of the upper bracket 32. A chuck 34 is fixedly installed at the end of the push rod 33 and is slidably connected inside the placement groove 11.

[0035] In this embodiment: when the support plate 2 moves down inside the placement groove 11, the protrusion 22 presses the end of the lower support 35, thereby enabling the rotating rod 31 to rotate. The upper support 32 rotates accordingly and pushes the push rod 33 to move. The clamp 34 at the end of the push rod 33 contacts the mold surface and quickly clamps the mold.

[0036] like Figure 4 As shown, a lower bracket 35 is fixedly installed on the surface of the rotating rod 31. The end of the lower bracket 35 is movably fitted with the lower surface of the bearing plate 2. A rotating shaft 36 is fixedly installed inside the rotating rod 31. Both ends of the rotating shaft 36 are fixedly connected to the inner wall of the rotating groove 14. Torsion springs 37 are fixedly connected to both ends of the rotating rod 31. The other end of the torsion spring 37 is fixedly connected to the inner wall of the rotating groove 14. The rotating shaft 36 passes through the inside of the torsion spring 37.

[0037] In this embodiment: by setting the rotating shaft 36 and the torsion spring 37, when the mold is removed from the surface of the support plate 2, the support plate 2 can be moved to the initial position to wait for the next use under the restoring action of the first spring 21 and the torsion spring 37.

[0038] like Figure 2 and Figure 4 As shown, the locking mechanism 4 includes a pull rod 41, which is slidably connected inside the base 1. A locking block 42 is fixedly installed at the end of the pull rod 41, and the insert block 23 is in contact with the surface of the locking block 42.

[0039] In this embodiment: the insert 23 is limited by the locking block 42. When the support plate 2 moves down inside the placement groove 11, the insert 23 moves down and inserts into the slot 13. At this time, the insert 23 squeezes the locking block 42, and the locking block 42 is retracted into the storage groove 43. After the insert 23 is fully inserted into the slot 13, the locking block 42 limits the insertion 23, thereby fixing the position of the support plate 2 inside the placement groove 11, and the clamp 34 can continuously clamp the mold.

[0040] like Figure 4 As shown, the base 1 has a storage slot 43 inside, the locking block 42 is slidably connected inside the storage slot 43, the surface of the locking block 42 is fixedly installed with a second spring 44, the other end of the second spring 44 is fixedly connected to the inner wall of the storage slot 43, and the pull rod 41 passes through the inside of the second spring 44.

[0041] In this embodiment: the storage groove 43 provides space for the temporary retraction of the locking block 42, and the second spring 44 enables the locking block 42 to be ejected after being subjected to pressure and to limit the insertion block 23. When the mold production is completed, simply pull the pull rod 41 to remove the locking block 42 from the surface of the insertion block 23, cancel the limitation on the insertion block 23, and the support plate 2 returns to its initial state.

[0042] In use, the mold is placed on the surface of the support plate 2. The mold moves the support plate 2 downward in the placement groove 11 by its own weight. When the protrusions 22 on both sides of the support plate 2 contact the end of the lower support 35, they squeeze the lower support 35. The lower support 35 drives the rotating rod 31 and the upper support 32 to rotate. The upper support 32 pushes the push rod 33 forward, which further enables the clamp 34 to quickly clamp the two sides of the mold. When the support plate 2 moves downward, the insert 23 is inserted into the slot 13. The insert 23 is limited by the locking block 42, so that the clamp 34 can continuously clamp the mold surface. After the mold is produced, the mold is removed and the pull rod 41 is pulled to move the locking block 42 away from the surface of the insert 23 and release the limiting effect on the insert 23. Under the action of the first spring 21 and the torsion spring 37, the support plate 2 can be moved to the initial position to wait for the next use.
