Description

Technical Field

[0001] The utility model relates to the technical field of casting molds, and particularly relates to a bottomless mold demoulding structure and a casting mold device. Background Art

[0002] The processing and production of cold-setting products often widely adopt the method of casting. By pouring molten raw materials into a mold, and after cooling and forming, demoulding treatment is carried out, so as to achieve the purpose of large-scale processing and production, and to maintain the consistency of products as much as possible during the processing and production process.

[0003] The current molds are generally integral molds. The opening of the mold faces upward to receive the casting material. After the product cools to a certain extent, the mold is flipped for demoulding, or an upward ejection force is applied from the bottom of the mold for demoulding, so as to achieve the effect of ejecting the product. In actual production, there is a situation where the casting material adheres to the cavity surface of the mold. Even if a demoulding agent is added, it is difficult to completely eliminate the adhesion. Therefore, demoulding difficulties often occur, and auxiliary methods such as knocking and pushing are required to assist in demoulding, resulting in product damage or mold deformation.

[0004] It can be seen that there is still room for improvement in the current casting demoulding process of cold-setting products. It should be optimized to improve the convenience of demoulding and reduce the damage to products and molds. Therefore, a more reasonable technical solution should be proposed to solve the technical problems existing in the prior art. Summary of the Utility Model

[0005] To at least overcome one of the above-mentioned defects, the utility model proposes a bottomless mold demoulding structure and a casting mold device. By optimizing and improving the structure of the casting mold, the casting material can be kept formed in the mold cavity and can be quickly demoulded, reducing the adhesion to the cavity, and avoiding damage to the product and the mold during the demoulding process.

[0006] To achieve the above purpose, the demoulding structure disclosed by the utility model can adopt the following technical solutions:

[0007] A bottomless mold demoulding structure includes a mold frame. A number of vertically penetrating forming holes are formed on the mold frame. A mold bottom plate is arranged below the mold frame, and the mold bottom plate fits the lower surface of the mold frame and cooperates with the forming holes to form a cavity. The mold bottom plate opens and closes relative to the mold frame to close the cavity for casting or open the cavity for demoulding.

[0008] For the above-mentioned disclosed demoulding structure, after the cavity is formed by the cooperation of the mold frame and the mold bottom plate, casting and cold setting are carried out, and after the mold bottom plate is opened, the material is demoulded downward to release the material. In this way, not only the sealing performance of casting and forming is improved, and the leakage of materials is reduced; but also the demoulding efficiency is improved, and at the same time, damage to the material or the mold during the demoulding process is avoided.

[0009] Furthermore, in the present utility model, the setting method of the die bottom plate can be realized through various solutions, which is not uniquely limited. Here, an optimization is carried out and one feasible option is proposed: the die bottom plate is connected to the movable seat and is opened and closed through the movable seat. When adopting such a solution, the movable seat can drive the die bottom plate to open the cavity or close the cavity. When the cavity is closed, casting is carried out, and when the cavity is opened, demoulding is carried out.

[0010] Furthermore, the structure of the movable seat can be constructed in various forms, which is not uniquely limited. Here, an optimization is carried out and one feasible option is proposed: the movable seat includes a seat plate and a shaft portion that cooperates with the seat plate, and the seat plate rotates around the shaft portion; the die bottom plate is arranged on the seat plate and rotates synchronously with the seat plate. When adopting such a solution, a shaft hole is provided on the seat plate and is rotationally matched with the shaft portion. In some other solutions, the shaft portion can also be directly arranged on the seat plate and cooperate with the external structure through the shaft portion.

[0011] Furthermore, in some solutions, the movement form of the movable seat can be changed from relative centering rotation to relative sliding lifting and even deflection, etc.

[0012] Furthermore, in order to maintain the stability and reliability of the casting and demoulding processes, an optimization is carried out here and one feasible option is proposed: the shaft portion and the seat plate are relatively fixed to the die frame. When adopting such a solution, when the die frame is a movable structure, the shaft portion and the seat plate move synchronously with the die frame, and when the die frame is a fixed structure, the shaft portion and the seat plate are fixed synchronously with the die frame.

[0013] Furthermore, there are various solutions for the die bottom plate to close or open the cavity, which is not uniquely limited. Here, an optimization is carried out and one feasible option is proposed: the movable seat cooperates with a guiding component, and the guiding component is used to guide the movement of the movable seat to drive the opening and closing of the die bottom plate. When adopting such a solution, when the die frame is a movable structure and the shaft portion and the seat plate move synchronously with the die frame, the guiding component can adopt a non-powered structure, and the seat plate can be opened or closed by abutting against the guiding component during the movement; when the die frame is a fixed structure, the guiding component can adopt a structure with its own power to move, and by changing the position, it abuts against different movable seats to drive the movable seat to drive the die bottom plate to complete the closing of the cavity.

[0014] Furthermore, in the present invention, the structure of the guide assembly can be constructed into a variety of schemes, which are not limited to a single one. Here, an optimization is made and one of the feasible options is proposed: the guide assembly includes a locking mechanism, the locking mechanism includes a movable locking bar, and the movable seat includes a locking groove that cooperates with the locking bar. When the locking groove enters the locking position, the locking bar moves and engages with the locking groove to lock the movable seat at a set angle. When such a scheme is adopted, the engagement time can be set according to the cooling speed of the material. After the material is cooled and formed, the locking bar can be set to leave the locking groove. At this time, the movable seat drives the mold bottom plate to open the cavity to realize demoulding and unloading. When an annular circulating casting system is set, the locking bar is arranged in an annular manner and an opening section is set. When the seat plate rotates to the opening section of the locking bar, demoulding and unloading are carried out. When the seat plate rotates to other positions, casting processing and production are carried out.

[0015] Furthermore, in the present invention, the structure of the guide assembly is not limited to a single one, and optimization is performed here and feasible options are proposed: the guide assembly also includes a mold clamping mechanism, and the mold clamping mechanism includes a column and a mold clamping table arranged on the column, and the mold clamping table is used to abut against the driving movable seat and make the mold base plate fit the lower surface of the mold frame. When such a solution is adopted, the mold clamping table can be screwed to the column, or connected and matched by other fasteners; when the mold base plate and the movable seat move with the mold frame, the mold clamping structure can be set to synchronously follow the movement and cooperate accordingly; when the mold base plate and the movable seat are fixed with the mold frame, the mold clamping structure can be fixedly set and cooperate with the movable seat accordingly.

[0016] Furthermore, in order to better demould and discharge the material, an optimization is made here and one of the feasible options is proposed: including a discharge rod, which is telescopic from the top of the cavity to push the molding material down. When such a solution is adopted, the discharge rod can be driven by a telescopic mechanism to rise and fall, and each molding hole corresponds to a discharge rod.

[0017] Furthermore, the structure of the forming hole can be constructed in various forms, which are not limited to a single one. Here, an optimization is made and one feasible option is proposed: the forming hole runs through the upper surface of the mold frame to the lower surface, and the inner diameter of the forming hole gradually increases from top to bottom. When such a scheme is adopted, the forming hole is a straight hole; in some schemes, the forming hole is also set as a non-straight rectangular hole that is small at the top and large at the bottom.

[0018] The above content describes the demoulding structure. The utility model also discloses a casting mold device, which is described below:

[0019] A bottomless mold casting device comprises a frame on which the demoulding structure described above is arranged.

[0020] Compared with the prior art, some beneficial effects of the technical solution disclosed in the utility model include:

[0021] Through the cavity that opens and closes downward, not only the stability and reliability of the casting process are ensured, but also the convenience of demoulding after casting is improved, avoiding damage to the product and the casting mold. Therefore, the casting and demoulding processes of cold-set products can be made more convenient. Description of the Drawings

[0029] The present invention will be further explained below in conjunction with the drawings and specific embodiments.

[0030] In view of the many deficiencies in the existing casting molding technology, the following embodiments are optimized to overcome the defects in the existing technology.

[0031] Embodiment 1

[0032] As Figures 1 to 4As shown in the figure, this embodiment provides a bottomless mold demolding structure, which includes a mold frame 2. A number of vertically penetrating forming holes 201 are formed on the mold frame 2. A mold bottom plate 4 is arranged below the mold frame 2, and the mold bottom plate 4 fits the lower surface of the mold frame 2 and cooperates with the forming holes 201 to form a cavity. The mold bottom plate 4 opens and closes relative to the mold frame 2 to close the cavity for casting or open the cavity for demolding.

[0033] In the demolding structure disclosed in this embodiment, after the cavity is formed by the cooperation of the mold frame 2 and the mold bottom plate 4, casting and cold solidification molding are carried out, and after the mold bottom plate 4 is opened, the material is demolded downward to release the material. In this way, not only the sealing performance of the casting molding is improved, and the leakage of materials is reduced, but also the demolding efficiency is improved, and the damage to the material or the mold during the demolding process is avoided.

[0034] In this embodiment, the setting method of the mold bottom plate 4 can be realized through various schemes, and it is not uniquely limited. This embodiment is optimized and one feasible option is adopted: the mold bottom plate 4 is connected to a movable seat and opens and closes through the movable seat. When adopting such a scheme, the movable seat can drive the mold bottom plate 4 to open or close the cavity. When the cavity is closed, casting is carried out, and when the cavity is opened, demolding is carried out.

[0035] The structure of the movable seat can be constructed in various forms, and it is not uniquely limited. This embodiment is optimized and one feasible option is adopted: the movable seat includes a seat plate 3 and a shaft part 301 that cooperates with the seat plate 3. The seat plate 3 rotates around the shaft part 301. The mold bottom plate 4 is arranged on the seat plate 3 and rotates synchronously with the seat plate 3. When adopting such a scheme, a shaft hole is arranged on the seat plate 3 and is rotationally matched with the shaft part 301. In some other embodiments, the shaft part 301 can also be directly arranged on the seat plate 3 and cooperate with the external structure through the shaft part 301.

[0036] Furthermore, in some schemes, the moving form of the movable seat can be changed from relative centering rotation to relative sliding lifting and so on.

[0037] In order to maintain the stability and reliability of the casting and demolding processes, this embodiment is optimized and one feasible option is adopted: the shaft part 301 and the seat plate 3 are relatively fixed to the mold frame 2. When adopting such a scheme, when the mold frame 2 is a movable structure, the shaft part 301 and the seat plate 3 move synchronously with the mold frame 2. When the mold frame 2 is a fixed structure, the shaft part 301 and the seat plate 3 are fixed synchronously with the mold frame 2.

[0038] There are multiple solutions for the mold base plate 4 to close or open the cavity, and it is not uniquely defined. In this embodiment, optimization is carried out and one feasible option is adopted: the movable seat cooperates with the guiding component, and the guiding component is used to guide the movement of the movable seat to drive the opening and closing of the mold base plate 4. When adopting such a solution, when the mold frame 2 is a movable structure and the shaft portion 301 and the seat plate 3 move synchronously with the mold frame 2, the guiding component can adopt a non-powered structure, and the seat plate 3 can be opened or closed by abutting against the guiding component during the movement; when the mold frame 2 is a fixed structure, the guiding component can adopt a structure with its own power to move, and the cavity is closed by changing the position to abut against different movable seats to drive the mold base plate 4 to complete the cavity closing.

[0039] In this embodiment, the structure of the guiding component can be constructed in multiple solutions, and it is not uniquely defined. In this embodiment, optimization is carried out and one feasible option is adopted: the guiding component includes a locking mechanism, the locking mechanism includes a movable locking bar 8, and the movable seat includes a locking groove 9 that cooperates with the locking bar 8. When the locking groove 9 enters the locking position, the locking bar 8 moves to engage with the locking groove 9 to lock the movable seat at a set angle. When adopting such a solution, the meshing time can be set according to the cooling speed of the material. After the material is cooled and formed, the locking bar 8 can be set to leave the locking groove 9. At this time, the movable seat drives the mold base plate 4 to open the cavity to realize demolding and discharging. When a circular circulating casting system is set, the locking bar 8 is arranged in a ring shape and an opening section is provided. When the seat plate 3 rotates to the opening section of the locking bar 8, demolding and blanking are carried out, and when the seat plate 3 rotates to other positions, casting processing and production are carried out.

[0040] In this embodiment, the structure of the guiding component is not uniquely defined. In this embodiment, optimization is carried out and a feasible option is adopted: the guiding component further includes a mold closing mechanism, the mold closing mechanism includes a column 5 and a mold closing table 6 arranged on the column 5, and the mold closing table 6 is used to abut against and drive the movable seat to make the mold base plate 4 fit against the lower surface of the mold frame 2. When adopting such a solution, the mold closing table 6 can be threadedly fitted to the column 5 or can be connected and fitted by other fasteners; when the mold base plate 4 and the movable seat move with the mold frame 2, the mold closing structure can be set to move synchronously and cooperate correspondingly; when the mold base plate 4 and the movable seat and the mold frame 2 are all fixed, the mold closing structure can be fixedly arranged and cooperate with the movable seat correspondingly.

[0041] In order to better demold and discharge, in this embodiment, optimization is carried out and one feasible option is adopted: it further includes a discharge rod 7, and the discharge rod 7 extends and retracts downward from above the cavity to push the formed material to fall. When adopting such a solution, the discharge rod 7 can be driven by a telescopic mechanism to move up and down, and there is a discharge rod 7 corresponding to each forming hole 201.

[0042] The structure of the forming hole 201 can be constructed in various forms and is not uniquely limited. In this embodiment, optimization is carried out and one of the feasible options is adopted: the forming hole 201 penetrates from the upper surface to the lower surface of the mold frame 2, and the inner diameter of the forming hole 201 gradually increases from top to bottom. When such a scheme is adopted, the forming hole 201 is a straight hole; in some schemes, the forming hole 201 is also set as a lofting rectangular hole with a smaller upper part and a larger lower part.
