Description

Technical Field

[0001] The utility model relates to the technical field of refractory material forming molds, in particular to a universal opening and closing structure of a mold. Background Art

[0002] A refractory molding mold is a mold used for rapid molding of liquid boron nitride fused with paraffin. Generally, such molds have a docking opening, which requires a screw-nut locking method. The basic screw-nut locking method is cumbersome to assemble and lock, and requires a wrench to assist in locking, which is time-consuming and labor-intensive, and requires repeated steps before and after demolding.

[0003] Based on this, the utility model designs a universal mold opening and closing structure to solve the above problems. Utility Model Content

[0004] The purpose of the present invention is to provide a universal mold opening and closing structure to solve the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A universal mold opening and closing structure includes a through-hole locking block and a threaded locking block for welding on both sides of the mold opening. The through-hole locking block and the threaded locking block are threadedly tightened by a bolt mechanism. The bolt mechanism includes a butterfly head bolt, a locking die nut and a mold opening threaded gasket. The through-hole locking block is provided with a through hole. The centers of the threaded locking block and the mold opening threaded gasket are both provided with screw holes that cooperate with the butterfly head bolt. The butterfly head bolt thread passes through the threaded locking block, and the outer end of the butterfly head bolt passes through the through-hole locking block and is threadedly sleeved on the locking die nut. The mold opening threaded gasket is sleeved between the through-hole locking block and the threaded locking block.

[0007] Preferably, the outer side walls of the locking nut and the mold opening threaded gasket are provided with angled surfaces for easy rotation.

[0008] Preferably, the mold-opening threaded gasket includes a center block and a deformation part, and a screw hole for cooperating with the butterfly head bolt thread is opened through the axis of the center block, and the top and bottom surfaces of the mold-opening threaded gasket are respectively fixed with deformation parts for deformation and tightening.

[0009] Preferably, the deformation portion includes a tightening ring.

[0010] Preferably, the abutting ring is a funnel-shaped thin metal sheet opening outward.

[0024] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-6 , the utility model provides a technical solution:

[0026] A universal mold opening and closing structure, comprising a through-hole locking block 1 and a threaded locking block 2 for welding on both sides of the mold opening, wherein the through-hole locking block 1 and the threaded locking block 2 are threadedly tightened by a bolt mechanism, wherein the bolt mechanism comprises a butterfly head bolt 3, a mold locking nut 4 and a mold opening threaded gasket 5, wherein the through-hole locking block 1 is provided with a through hole, and the centers of the threaded locking block 2 and the mold opening threaded gasket 5 are both provided with screw holes that cooperate with the butterfly head bolt 3, the butterfly head bolt 3 is threadedly passed through the threaded locking block 2, the outer end of the butterfly head bolt 3 passes through the through-hole locking block 1 and is threadedly sleeved on the mold locking nut 4, and the mold opening threaded gasket 5 is sleeved between the through-hole locking block 1 and the threaded locking block 2;

[0027] During operation, weld the through-hole locking block 1 and the threaded locking block 2 to the mold, thread the butterfly head bolt 3 to the threaded locking block 2, connect the mold opening threaded gasket 5 to the butterfly head bolt 3 and adjust the appropriate position, then pass the butterfly head bolt 3 through the through-hole locking block 1, and finally install the mold locking nut 4; to lock or open the mold, you only need to adjust the locking nut 4 and the mold opening threaded gasket 5;

[0028] The mold opening threaded gasket 5 is provided to pre-adjust the position, as shown in the butterfly head bolt 3 in the figure. At this time, it is assumed that the mold is locked. If unlocking is required, the mold locking nut 4 needs to be rotated for demoulding. However, at this time, the mold locking nut 4 is subjected to a large force on the side. During the rotation of the mold locking nut 4, the through-hole locking block 1 and the threaded locking block 2 tend to move away from each other, causing the mold locking nut 4 to be difficult to rotate, or the mold locking nut 4 is prone to sudden collapse. At this time, the position can be changed by rotating the mold opening threaded gasket 5. As shown in the mold locking nut 4 in the figure, the mold opening threaded gasket 5 can be pre-adjusted to the side close to the through-hole locking block 1. During the loosening process of the mold locking nut 4, the distance between the through-hole locking block 1 and the threaded locking block 2 becomes larger, and the mold opening threaded gasket 5 can be against the inner side of the through-hole locking block 1. At this time, the axial force on one side of the locking nut 4 along the butterfly head bolt 3 is greatly reduced, and the locking nut 4 can be easily removed. At this time, the mold opening threaded gasket 5 can be rotated to achieve the continued expansion of the distance between the through-hole locking block 1 and the threaded locking block 2 to achieve the unlocking action. It can be seen that although the equivalent number of turns of the locking nut 4 and the mold opening threaded gasket 5 for jointly rotating and unlocking is actually unchanged, it can prevent the locking nut 4 and the butterfly head bolt 3 internal threads from being subjected to force toward one side when the locking nut 4 is unlocked, causing the internal threads to deform. It can also effectively prevent the risk of the through-hole locking block 1 directly pulling the locking nut 4 off the end of the butterfly head bolt 3 when the locking nut 4 is about to be unlocked, thereby damaging the end thread of the butterfly head bolt 3.

[0029] The outer side walls of the mold locking nut 4 and the mold opening threaded gasket 5 are provided with angled surfaces for easy rotation;

[0030] During operation, the provided angled surface is mainly used to facilitate the rotation of the locking nut 4 or the mold opening threaded gasket 5, such as a four-sided surface or a six-sided surface.

[0031] The mold-opening threaded gasket 5 includes a center block and a deformation portion. A screw hole for threaded engagement with the butterfly head bolt 3 is provided through the axis of the center block. The top and bottom surfaces of the mold-opening threaded gasket 5 are respectively fixed with deformation portions for deformation and tightening.

[0032] Wherein, the deformation portion includes a tightening ring piece 6;

[0033] The abutting ring 6 is a funnel-shaped thin metal sheet with an outward opening.

[0034] During operation, since general gaskets are mostly thin sheets with through holes, they do not have the function of adjusting and maintaining the position on the butterfly head bolt 3, and do not have the function of resisting extrusion and tightening. Therefore, the main body of the mold thread gasket 5 is set as a block-shaped center block, so that the screw hole can be opened conveniently. In order to further prevent the through hole locking block 1 or the thread locking block 2 from directly impacting the mold thread gasket 5, which will also cause the internal thread here to deform, a deformation part is set. The deformation part is designed here as a thin sheet-shaped tightening ring 6. When the mold thread gasket 5 is tightened on the through hole locking block 1 or the thread locking block 2, the tightening ring 6 can have a tendency to expand outward and deform, thereby giving the mold thread gasket 5 the effect of a spring gasket, which can further ensure the tightening effect and impact resistance of the mold thread gasket 5.
