Detailed Description

Before the present invention is described in detail, it should be noted that like components are represented by like numerals throughout the following description.

Referring to fig. 1, 2 and 3, the first embodiment of the casting mold device of the present invention is adapted to allow a concrete material to be injected and cured into a concrete product, and comprises an outer mold unit 1, an inner mold unit 2, and a tension unit 3.

It is added that the concrete material can be, but is not limited to, a resin or cement type. In addition, in one embodiment of this embodiment, the concrete product is a barrel-shaped structure, i.e. a structure including a bottom surface, but not limited thereto.

The outer mould unit 1 comprises an outer mould 11 and a base plate 12.

Referring to fig. 2, 4 and 5, the outer mold 11 is disposed on the bottom plate 12 and has an inner surface 111 defining a through hole 112 around an axis.

The inner mold unit 2 is disposed in the through hole 112, and includes a housing 21 surrounding the axis and a fixing seat 22.

The housing 21 is adapted to be supplied with a cooling liquid, and has an inner peripheral surface 211, an outer peripheral surface 212 opposite to the inner peripheral surface 211, a top end surface 213 connecting the inner peripheral surface 211 and the outer peripheral surface 212 and distant from the base plate 12, a bottom end surface 214 opposite to the top end surface 213, two cooling holes 215 formed in the top end surface 213, and a plurality of mounting holes 217 formed in the top end surface 213.

In this embodiment, the cooling liquid is provided by a temperature reduction device (not shown) and enters the cooling space 216 from the temperature reduction device through a pipeline from at least one of the cooling holes 215. It should be noted that the cooling liquid is also recovered from the cooling space 216 to the temperature reduction device through at least one cooling hole 215. The cooling liquid circulates between the temperature reduction device and the cooling space 216, so that the housing 21 can maintain a low-temperature state in the cooling process.

The fixing seat 22 extends from the inner circumferential surface 211 of the housing 21 to the opening and is located in the inner mold space 218.

The outer peripheral surface 212, the bottom end surface 214 of the shell 21 and the inner surface 111 of the outer mold 11 are adapted for the concrete material to be injected and cured into the concrete product 4.

The tension unit 3 is detachably mounted to the inner mold unit 2, and includes a first tension group 31 detachably fixed to the housing 21, and a second tension group 32 detachably connected to the first tension group 31. Specifically, in the present embodiment, the inner mold unit 2 further has a fixing seat 22 extending from the inner circumferential surface 211 toward the opening of the inner mold space 218, and the first pulling force unit 31 may be, but is not limited to, detachably mounted on the fixing seat 22 by a screw.

The first pulling force group 31 and the second pulling force group 32 are respectively used for applying a first pulling force and a second pulling force perpendicular to the direction of the bottom end surface 214 to the housing 21, so as to drive the inner mold unit 2 to move away from the outer mold unit 1. That is, the first tensile force and the second tensile force are parallel to the up and down directions of fig. 4 to 7.

Referring to fig. 2, 4 and 6, in the embodiment, specifically, the first pulling force group 31 has two supporting members 312 removably abutting against the outer mold unit 1, and a jack 311 removably disposed on the supporting members 312 and detachably mounted on the fixing base 22. The jack 311 has a cylinder 313 abutting against the support 312, and a rod 314 which is extendable and retractable with respect to the cylinder 313 and connects the inner mold unit 2. The second tension group 32 has a crane 321 removably connected to the jack 311. The crane 321 has a hanger 322 detachably mounted to the cylinder 313 of the jack 311, and a lifting member 323 connected to the hanger 322 and for moving the hanger 322 up and down. It should be noted that, in the present embodiment, the jack 311 is an oil jack, but not limited thereto, and the number of the supporting members 312 is not limited to two.

Referring to fig. 5, when a concrete product 4 is to be manufactured, the outer mold unit 1 is first disposed on the bottom plate 12 to close one side of the through hole 112 of the outer mold 11, then a top plate 13 is fixed on the top end surface 213 of the inner mold 21, the top plate 13 and the inner mold unit 2 are disposed in the through hole 112 of the outer mold 11 with the fixing base 22 facing upward (in a direction opposite to the bottom plate 12), and a concrete material is injected between the outer peripheral surface 212 and the bottom end surface 214 of the housing 21 of the inner mold unit 2 and the inner surface 111 of the outer mold 11 through a hole (not shown) in the top plate 13 and is allowed to stand to solidify into the concrete product 4. Then, the demolding method of the present invention is performed.

Referring to fig. 4 and 6, the demolding method of the present invention includes the following steps (a) to (D):

a step (A): mounting the first set of pulling forces 31 to the inner mould unit 2.

Specifically, after the top plate 13 in fig. 5 is removed, the supporting member 312 of the first pulling force group 31 is placed on the top surface of the outer mold unit 1 and spans the top end surface 213 of the shell 21 of the inner mold unit 2, and the jack 311 is disposed on the supporting member 312, and the jack 311 is fixed to the fixing base 22 by screws.

A step (B): cooling the inner mold unit 2 to reduce the outer diameter of the shell 21, so as to generate a micro gap between the outer peripheral surface 212 and the bottom end surface 214 of the shell 21 and the concrete product 4, and applying a first pulling force perpendicular to the bottom end surface 214 direction to the shell 21, so as to move the inner mold unit 2 in a direction away from the outer mold unit 1, so as to loosen the inner mold unit 2 relative to the concrete product 4.

In the step (B), the inner mold unit 2 is cooled by injecting a cooling liquid into the cooling space 216 of the inner mold unit 2. In the step (B), the first pulling force is applied by the jack 311 of the first pulling force group 31, and the rod 314 of the jack 311 extends and contracts relative to the cylinder 313 to drive the shell 21 to move in a direction away from the outer mold unit 1, so that the bottom end surface 214 of the shell 21 moves away from the outer mold unit 1.

It should be noted that, the movement of the shell 21 away from the outer mold unit 1 by applying the first pulling force mainly loosens the shell 21 relative to the concrete product 4, thereby improving the demolding efficiency of the shell 21.

Thus, when the inner mold is cooled and shrunk, the bottom end surface 214 of the shell 21 is separated from the concrete product 4 by the first tension assistance, so that even if the shrinkage degree of the shell 21 is insufficient in winter or in a low-temperature environment, the bottom end surface 214 of the shell 21 can be separated from the concrete product 4 by the first tension assistance without increasing the shrinkage degree of the shell by an additional process, and thus, the operation time can be effectively reduced. In addition, by applying a first pulling force, it is also helpful to identify the degree of shrinkage of the inner mold unit 2, such that if the first pulling force is gradually increased until the shell 21 still cannot be moved by the shell 21, which indicates that the degree of shrinkage of the shell 21 of the inner mold unit 1 is insufficient, no micro-gap is generated between the outer circumferential surface 212 of the shell 21 and the finished concrete product 4, and if the pulling force is reduced in the process of gradually applying the first pulling force to the shell 21 and the shell 21 can be slightly moved, which indicates that the outer circumferential surface 212 and the bottom end surface 214 of the shell 21 and the finished concrete product 4 are loosened, the next step can be continued.

It should be noted that, in the step (B), during the cooling of the inner mold unit 2, the cooling liquid continuously circulates in the inner mold unit 2 and the cooling device, so that the cooling liquid can be maintained in a low temperature state during the cooling process.

Step (C): then, the second pulling force is applied to the inner mold unit 2 in a direction perpendicular to the bottom end surface 214, so that the inner mold unit 2 moves away from the concrete product 4, and the inner mold unit 2 is separated from the concrete product 4.

In the step (C), the second pulling force is applied by the crane 321 of the second pulling force group 32, specifically, after the hanger 322 of the crane 321 is connected to the cylinder 313 of the jack 311, the jack 311 and the connected inner mold unit 2 are lifted by the lifting member 323 to be separated from the through hole 112, so that the shell 21 is separated from the concrete product 4.

It should be noted that, in the step (B) and the step (C), the first pulling force may be provided by both the jack 311, or the first pulling force and the second pulling force may be provided by both the crane 321. In addition, the device for providing the first pulling force and the second pulling force is not limited to the embodiment.

Step (D): the outer mould unit 1 is removed and the outer mould unit 1 is separated from the finished concrete product 4.

Referring to fig. 7 to 10, the second embodiment of the mold apparatus of the present invention is substantially the same as the first embodiment, and the difference is only: the base plate 12 of the second embodiment is detachably mounted to the top end surface 213 of the housing 21.

When the concrete product 4 is to be manufactured, the bottom plate 12 is first installed on the top end surface 213 of the housing 21 of the inner mold unit 2, for example, screws are used to pass through the bottom plate 12 and the installation holes 217 located on the top end surface 213 of the housing 21, then the inner mold unit 2 and the bottom plate 12 are placed into the through holes 112 of the outer mold 11, and the bottom plate 12 is locked on the top surface 113 of the outer mold 11, then the bottom plate 12, the inner mold unit 2 and the outer mold unit 1 are turned over (assisted by the second pulling force set 32) to position the bottom plate 12 at the lower side, and the bottom surface 114 of the outer mold unit 1 and the bottom end surface 214 of the housing 21 are upward, then concrete material is injected among the bottom plate 12, the outer circumferential surface 212 of the housing 21 of the inner mold unit 2 and the inner surface 111 of the outer mold 11, and is left to cure the concrete material into the concrete product 4 (as shown in fig. 7). Next, the inner mold unit 2 and the outer mold unit 1 are turned over again so that the bottom plate 12 is located at the upper side and the top surface 113 of the outer mold unit 1 and the top end surface 213 of the housing 21 are directed upward (as shown in fig. 8), and the bottom plate 12 is removed (as shown in fig. 9), so that the steps (a) to (D) of the mold release method can be performed.

Referring to fig. 10, it is to be noted that the outer mold 11 and the shell 21 of the foregoing embodiment may also be a quadrilateral, or other polygonal, oval shape.

To sum up, the present invention provides a method and a device for demolding, which is assisted by applying the first external force when the outer diameter of the housing 21 of the inner mold unit 2 is cooled and reduced, so that the inner mold unit 2 is not loosened with respect to the concrete product 4 and is not easily affected by the weather or the environmental temperature, thereby achieving the object of the present invention.

The above description is only an example of the present invention, and the scope of the present invention should not be limited thereby, and all the simple equivalent changes and modifications made according to the claims and the description of the present invention are still within the scope of the present invention.
