Description

Technical Field

[0001] This utility model relates to the field of mold structure technology, and in particular to a cemented carbide mold structure with strong impact resistance. Background Technology

[0002] Carbide molds are molds made of carbide materials. Carbide is an alloy material made by powder metallurgy of hard compounds of refractory metals (such as tungsten carbide, titanium carbide, etc.) and binder metals (such as cobalt, nickel, etc.). It has the characteristics of high hardness, high wear resistance, and high compressive strength.

[0003] Existing cemented carbide molds typically have guiding mechanisms, but the stroke of these mechanisms is mostly fixed. When used with mold opening and closing structures with different strokes, precise adjustments to the mold opening and closing structure are required. If the adjustments are not precise enough, it can easily damage the guiding mechanism of the mold itself or prevent the space between the upper and lower molds from fully opening after the mold is opened, making operation inconvenient. Therefore, we propose a cemented carbide mold structure with strong impact resistance. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a cemented carbide mold structure with strong impact resistance, which can solve the problems existing in the background art.

[0005] The technical solution of this utility model is:

[0006] A high-impact-resistant cemented carbide mold structure includes a fixed connecting base, a fixed guide mechanism symmetrically fixedly connected to the top of the fixed connecting base, a lower module fixedly connected to the top of the fixed connecting base, a through hole adapted to the fixed guide mechanism on the inner side of the lower module, and an upper module movably sleeved on the outer surface of the fixed guide mechanism.

[0007] In a further technical solution, the fixed connection base includes a base body, the interior of which is symmetrically provided with fixed through holes, and the fixed guide mechanism is located at the top of the fixed through holes.

[0008] In a further technical solution, the fixed guide mechanism includes a fixed sleeve, a movable connecting rod is movably connected inside the fixed sleeve, a threaded rod is fixedly connected to the bottom end of the movable connecting rod, a force-bearing base is movably sleeved on the outer surface of the threaded rod, a fastening nut is threadedly connected to the outer surface of the threaded rod, a force-bearing spring is placed inside the fixed sleeve, the force-bearing spring is located at the top of the force-bearing base and on the outer surface of the movable connecting rod, a connecting top rod is fixedly connected to the top end of the movable connecting rod, and a limiting top plate is fixedly connected to the top end of the connecting top rod.

[0009] In a further technical solution, the edge of the load-bearing chassis slides and fits against the inner side of the fixed sleeve.

[0010] In a further technical solution, the bottom of the base body is symmetrically provided with fixing grooves, and the bottom of the base body is symmetrically provided with threaded mounting holes. The threaded mounting holes are located at the inner end of the fixing grooves, and fastening bolts are movably connected to the inner side of the threaded mounting holes. Connecting plugs are movably sleeved on the outer side of the fastening bolts.

[0011] In a further technical solution, the outer surface of the connecting block is in contact with the inner surface of the fixing groove.

[0012] In a further technical solution, the top of the connecting plug is in contact with the bottom end of the threaded rod.

[0013] The beneficial effects of this utility model are:

[0014] 1. With the fixed guide mechanism, during use, when the mold is opened between the lower and upper modules, the mold opening mechanism can drive the upper module to move. It moves on the outer side of the fixed guide mechanism without the need for precise adjustment of the stroke of the mold opening mechanism. When the upper module moves, it can stretch the top of the fixed guide mechanism and adjust itself. The overall structure is simple and the operation is convenient and quick.

[0027] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0028] Example:

[0029] like Figures 1-5 As shown, a hard alloy mold structure with strong impact resistance includes a fixed connecting base 1, a fixed guide mechanism 2 symmetrically fixedly connected to the top of the fixed connecting base 1, a lower module 3 fixedly connected to the top of the fixed connecting base 1, a through hole adapted to the fixed guide mechanism 2 on the inner side of the lower module 3, and an upper module 4 movably sleeved on the outer surface of the fixed guide mechanism 2.

[0030] The working principle of the above technical solution is as follows:

[0031] During use, when the lower module 3 and the upper module 4 open the mold with each other, the upper module 4 can move on the outer side of the surface of the fixed guide mechanism 2. Then, under the action of the mold opening mechanism, the upper module 4 can pull the fixed guide mechanism 2, so that the fixed guide mechanism 2 can adjust its extension on its own, which is convenient to operate.

[0032] In another embodiment, such as Figure 4 As shown, the fixed connection base 1 includes a base body 11, and the base body 11 has symmetrical fixed through holes 12 inside, and the fixed guide mechanism 2 is located at the top of the fixed through holes 12.

[0033] It facilitates the installation of internal components of the fixed guide mechanism 2, and also makes it easy to disassemble and replace internal components, making operation convenient.

[0034] In another embodiment, such as Figure 5 As shown, the fixed guide mechanism 2 includes a fixed sleeve 21, a movable connecting rod 22 is movably connected inside the fixed sleeve 21, a threaded rod 23 is fixedly connected to the bottom end of the movable connecting rod 22, a force-bearing base 24 is movably sleeved on the outer surface of the threaded rod 23, a fastening nut 25 is threadedly connected to the outer surface of the threaded rod 23, a force-bearing spring 26 is placed inside the fixed sleeve 21, the force-bearing spring 26 is located at the top of the force-bearing base 24 and on the outer surface of the movable connecting rod 22, a connecting top rod 27 is fixedly connected to the top end of the movable connecting rod 22, and a limiting top plate 28 is fixedly connected to the top end of the connecting top rod 27.

[0035] The upper module 4 can pull the limiting top plate 28, which drives the connecting top rod 27, movable connecting rod 22, threaded rod 23, force-bearing base plate 24 and fastening nut 25 to move, compressing the force spring 26, thereby making self-adjustment, which is convenient to use.

[0036] In another embodiment, such as Figure 5 As shown, the edge of the load-bearing chassis 24 slides and fits against the inner side of the fixed sleeve 21.

[0037] This allows the load-bearing chassis 24 to move stably inside the fixed sleeve 21, making operation convenient.

[0038] In another embodiment, such as Figure 4 As shown, the bottom of the base body 11 is symmetrically provided with a fixing groove 13 and a threaded mounting hole 14. The threaded mounting hole 14 is located at the inner end of the fixing groove 13. A fastening bolt 102 is movably connected to the inner side of the threaded mounting hole 14, and a connecting plug 101 is movably sleeved on the outer side of the fastening bolt 102.

[0039] The connecting plug 101 can be placed inside the fixing groove 13 and connected to the threaded mounting hole 14 by inserting the fastening bolt 102 into the end of the connecting plug 101. The connecting plug 101 is installed to seal the fixing groove 13 at the bottom of the base body 11, which is convenient to operate.

[0040] In another embodiment, such as Figure 4 As shown, the outer surface of the connecting block 101 is in contact with the inner surface of the fixing groove 13.

[0041] This allows the connecting block 101 to be stably positioned in the fixing groove 13, thus sealing the bottom of the base body 11.

[0042] In another embodiment, such as Figure 4 As shown, the top of the connecting block 101 is in contact with the bottom of the threaded rod 23.

[0043] When the connecting plug 101 is stably positioned inside the fixing groove 13, it contacts the bottom of the threaded rod 23, so that the internal components of the fixing guide mechanism 2 can be in a stable state, can be used stably, and are easy to operate.

[0044] The working principle of this utility model is as follows: During use, the whole assembly is first connected and assembled, and then the whole assembly is directly installed. Under the action of the mold opening mechanism pulling the upper module 4, the upper module 4 can move on the outer side of the surface of the connecting top rod 27, pulling the limiting top plate 28, driving the connecting top rod 27, movable connecting rod 22, threaded rod 23, force-bearing base 24 and fastening nut 25 to move, compressing the force spring 26, thereby adjusting its elongation and increasing the overall stroke. When the force spring 26 needs to be disassembled and replaced later, the fastening bolt 102 is first rotated and disassembled, the connecting block 101 is disassembled, and then the fastening nut 25 is rotated and disassembled, so that the force-bearing base 24 is detached from the outer side of the surface of the threaded rod 23, thereby enabling the force spring 26 to be quickly disassembled and replaced. The overall structure is simple and the operation is convenient and quick.

[0045] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
