TECHNICAL FIELD
[0001] The present application relates to the technical field of pouring molds, in particular to a pouring mold anti-falling structure. BACKGROUND
[0002] In order to facilitate the demolding of the sand core mold, the pouring mold is usually vertically arranged. During the demolding process, the movable mold moves and drives the sand core mold to move. Then, the sand core mold is separated from the movable mold by using a demolding device. At this time, the sand core mold will fall due to the influence of gravity. In order to ensure that the sand core mold is not damaged, a structure for placing the sand core mold to fall off is usually arranged on the static mold. The sand core mold is hoisted and transported after being completely cooled.
[0003] REFERENCE Figure 1 The prior art sand core mold 02 and static mold 01 are disclosed, which include an integrally formed boss 021. The boss 021 is arranged in a prism shape, and the larger end is connected with the sand core mold 02. The static mold 01 is provided with a groove 011 matched with the outer shape of the boss 021.
[0004] During demolding, the movable mold drives the sand core mold 02 to move to a specified position. At this time, the boss 021 is not completely separated from the groove 011. Then, the demolding device on the movable mold is started to open the sand core mold 02. At this time, the sand core mold 02 falls due to the weight. Then, the boss 021 abuts against the inner wall of the groove 011, and cooperates with the demolding device of the movable mold to realize the emptying and cooling of the sand core mold 02 on the static mold 01.
[0005] For the related technology in the above, however, the prior art only relies on the cooperation of the boss and the groove to realize the emptying of the sand core mold on the static mold. Since the boss is in a prism shape, there is a gap between the boss and the inner wall of the groove, and the sand core mold has the possibility of shaking and is prone to tilting, which reduces the stability of the emptying and cooling of the sand core mold, and there is a risk of falling during the subsequent hoisting and transporting of the sand core mold.

DETAILED DESCRIPTION
[0034] The following will be described in detail below with reference to the accompanying drawings. Figures 2-6 The present application will be further described in detail.
[0035] Embodiment 1 of the present application discloses a pouring mold anti-falling structure. Referring to Figure 2 and Figure 3 , the pouring mold anti-falling structure comprises a static mold 01 and a sand core mold 02. The static mold 01 is provided with a support block 1, and the support block 1 comprises a connecting portion 11 and a supporting portion 12. The connecting portion 11 is integrally formed with the supporting portion 12, and the surface of the connecting portion 11 is provided with external threads. The connecting portion 11 is threadedly connected to the static mold 01.
[0036] Referring to Figure 3 and Figure 4 , the supporting portion 12 is in the shape of a circular truncated cone, and the larger end of the supporting portion 12 is connected to the connecting portion 11. The sand core mold 02 is provided with a process hole 022 at a position corresponding to the supporting portion 12, and the supporting portion 12 is located in the process hole 022.
[0037] The implementation principle of the anti-falling structure of the pouring mold in the embodiment 1 of the application is as follows: when the sand core mold 02 is cooled, the sand core mold 02 is pushed out by the demolding device on the moving mold, at this time, the boss 021 on the sand core mold 02 is located in the groove 011 of the static mold 01, and the supporting part 12 is located in the process hole 022, and the sand core mold 02 is cooled and placed on the static mold 01, and a gap is left between the sand core mold 02 and the static mold 01.
[0038] A gap is left between the sand core mold 02 and the static mold 01, which increases the contact area of the sand core mold 02 and the air, and is beneficial to the heat dissipation of the sand core mold 02.
[0039] Through the cooperation of the supporting block 1 and the process hole 022, the sand core mold 02 is provided with an additional supporting position, and in addition, the boss 021 of the sand core mold 02 cooperates with the groove 011 of the static mold 01, so that the sand core mold 02 is supported at two positions, the possibility of shaking of the sand core mold 02 is reduced, the sand core mold 02 is kept in a state of cooling, the stability of the sand core mold 02 on the static mold 01 is improved, the subsequent hoisting of the sand core mold 02 is facilitated, and the risk of falling of the sand core mold 02 is reduced.
[0040] Embodiment 2: The difference between the embodiment 2 and the embodiment 1 is that the structure of the supporting block 1 is different.
[0041] Referring to Figure 5 and Figure 6 , the supporting block 1 comprises a fixing part 13 and a stabilizing part 14. The fixing part 13 is threadedly fitted on the static mold 01, and the stabilizing part 14 is in the shape of a circular truncated cone. The larger end of the stabilizing part 14 is fixedly connected with a sliding rod 141, the sliding rod 141 is a rectangular rod, and the edges of the sliding rod 141 are circularly arc-shaped. The sliding rod 141 with a rectangular cross section is beneficial to the installation of the fixing part 13. The sliding rod 141 penetrates through the fixing part 13 and is in sliding cooperation with the fixing part 13. The end of the sliding rod 141 away from the fixing part 13 is fixedly connected with a stop block 142, and the stop block 142 is in the shape of a cylinder. A reset member 143 is arranged on the sliding rod 141, the reset member 143 is a reset spring, the reset member 143 is sleeved on the sliding rod 141 and located between the stop block 142 and the fixing part 13, and the reset member 143 is used to make the stabilizing part 14 return to the initial position.
[0042] Referring to Figure 6 , the static mold 01 is provided with a containing hole 012 for containing the sliding rod 141, and the arc wall of the stop block 142 is attached to the inner wall of the containing hole 012. In the initial state, the stop block 142 is attached to the inner end wall of the containing hole 012. The stop block 142 is attached to the inner wall of the containing hole 012 to improve the stability of the stabilizing part 14.
[0043] Referring to Figure 5 and Figure 6In order to reduce the possibility of loosening of the fixed part 13, the static mold 01 is provided with a mounting groove 013, and the mounting groove 013 is provided with a locking washer 2, the locking washer 2 is sleeved on the fixed part 13, and is abutted between the bottom wall of the mounting groove 013 and the fixed part 13. By using the deformation force of the locking washer 2, the distance between the fixed part 13 and the static mold 01 is increased.
[0044] When demolding, the movable mold drives the sand core mold 02 to move, the stable part 14 moves with the sand core mold 02, the reset part 143 is compressed, and then the sand core mold 02 is pushed out by using the demolding device. The sand core mold 02 is pressed by the stable part 14 due to gravity (at this time, the adhesion on the stable part 14 disappears, and is in a static friction state with the process hole 022), through the cooperation of the convex boss 021 and the groove 011, the sand core mold 02 is stable on the static mold 01, and a gap is left between the sand core mold 02 and the static mold 01, realizing the empty cooling effect of the sand core mold 02.
[0045] The above are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application, therefore: any equivalent changes made on the structure, shape, principle of the present application should be covered within the protection scope of the present application.
