Description

Technical Field

[0001] The utility model relates to the field of processing molds, in particular to an automatic demoulding and shaping device. Background Art

[0002] In precision casting, the blank of the casting can be obtained after pouring, cooling and molding. The blank usually needs to be shaped and processed in other ways to obtain a product that meets the requirements.

[0003] The existing shaping device is generally provided with an upper mold and a lower mold. When performing the shaping work, the product to be shaped is usually placed on the lower mold, and then the upper mold is moved to close the upper mold and the lower mold, so as to shape the product inside. When the mold is opened after the shaping is completed, the product will be stuck on the upper mold due to the strong force between the upper mold and the product when the mold is closed. Therefore, manual demoulding is required to make the product fall off from the upper mold, which is time-consuming, labor-intensive and inefficient. In addition, due to the high pressure when the mold is closed, the product and the upper mold are usually tightly fitted, and it is difficult to demould by hand. Therefore, the staff is required to use tools to knock the product to make the product fall off from the upper mold, and the knocking may also cause certain damage to the product surface, affecting the product quality.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application. Example 1

[0037] Please refer to Figures 1 to 3 In a preferred embodiment, an automatic demoulding and shaping device is provided for shaping metal products, which includes a base plate 1, and an upper mold assembly 2 and a lower mold assembly 3 arranged on the base plate 1, the lower mold assembly 3 is used to place a product 6, the upper mold assembly 2 can be lifted and lowered in the vertical direction, and is used to shape the product 6 placed in the lower mold assembly 3, the upper mold assembly 2 includes two inclined guide pillars 23, wherein the bottom ends of the two inclined guide pillars 23 are inclined toward each other, the lower mold assembly 3 includes a fixed seat 31 and a demoulding movable block 32, the fixed seat 31 is used to place the product 6, the demoulding movable block 32 is provided with two, and is respectively located on both sides of the fixed seat 31, the demoulding movable block 32 is provided with an inclined hole 321 that matches the inclined guide pillar 23, the inclined hole 321 has the same inclination angle as the inclined guide pillar 23, the inclined guide pillar 23 is slidably penetrated in the inclined hole 321, the demoulding movable block 32 is slidably arranged on the base plate 1, and reciprocates in the horizontal direction driven by the inclined guide pillar 23.

[0038] If so, please continue to refer to Figure 2 and Figure 3When the shaping device in this embodiment is used, the shaping product 6 needs to be placed on the fixed seat 31 first, and then the upper mold assembly 2 is pressed down to close the upper mold assembly 2 and the lower mold assembly 3, so as to shape the product 6; the upper mold assembly 2 is provided with two inclined guide pillars 23, and the inclined guide pillars 23 move up and down with the lifting of the upper mold assembly 2, wherein, according to the direction shown in the figure, when the inclined guide pillars 23 move upward, the two demoulding blocks 32 move toward each other, and when the inclined guide pillars 23 move downward, the two demoulding blocks 32 move away from each other. Specifically, after the shaping device has finished shaping the product 6, when opening the mold, the upper mold assembly 2 moves upward, At this time, the product 6 will adhere or get stuck on the bottom of the upper mold assembly 2, and under the action of the inclined guide pin 23, the two demolding blocks 32 move toward each other and gradually move to the top of the product 6. As the upper mold assembly 2 continues to move, the bottom of the demolding block 32 contacts the product 6. As the upper mold assembly 2 continues to rise, the demolding block 32 generates a downward thrust on the product 6, causing the product 6 to fall off the upper mold assembly 2, completing automatic demolding. When the next shaping work is performed to close the mold, the upper mold assembly 2 moves downward. At this time, the demolding blocks 32 move away from each other under the action of the inclined guide pin 23, and can make way to avoid affecting the closing of the upper mold assembly 2 and the lower mold assembly 3.

[0039] It should be noted that, in the present embodiment, one demolding block 32 is connected to one corresponding inclined guide column 23, but in other embodiments, one demolding block 32 may be connected to multiple inclined guide columns 23, wherein the multiple inclined guide columns 23 connected to the same demolding block 32 have the same direction, therefore, one demolding block 32 is connected to at least one inclined guide column 23, and the specific number is not limited.

[0040] The upper mold assembly 2 also includes an upper mold plate 21 and a shaping mold 22. The shaping mold 22 is detachably connected to the bottom of the upper mold plate 21 and is perpendicular to the upper mold plate 21. The shaping mold 22 is used to shape the product 6 placed in the lower mold assembly 3. The shaping mold 22 is detachably connected to the bottom of the upper mold plate 21 and can be disassembled and replaced when shaping different types of products.

[0041] Furthermore, two inclined guide pillars 23 are respectively located on both sides of the shaping mold 22, and the top ends of the two inclined guide pillars 23 are connected to the bottom of the upper mold plate 21, and the bottom ends are inclined toward the shaping mold 22. Therefore, when the inclined guide pillars 23 rise, they can drive the demolding blocks 32 on both sides to move toward the shaping mold 22, thereby realizing automatic demolding of the product 6 when the mold is opened.

The output end 413 of the lifting drive member 41 is connected to the top surface of the upper mold plate 21. The upper mold plate 21 is slidably connected to the guide rail 42. In this way, the upper mold plate 21 can move up and down under the drive of the lifting drive member 41, thereby driving the bottom shaping mold 22 to shape the product 6 and complete mold opening and closing.

[0043] Furthermore, a displacement sensor 411 is provided on the side of the lifting drive member 41, and the displacement sensor 411 can detect the moving distance of the upper template 21 to ensure that the bottom shaping mold 22 is pressed down into place, avoid the situation of not moving into place, and ensure the effect of product shaping.

[0044] Optionally, the lifting drive member 41 is a cylinder, and the output end 413 of the cylinder is connected to the upper template. In addition to the cylinder, other types of drive members can also be used, such as a linear motor, etc., which are not specifically limited here.

[0045] Optionally, the displacement sensor 411 can be a photoelectric sensor or other types of sensors. Further optionally, a prompt light 412 is provided on one side of the photoelectric sensor, and the prompt light 412 is electrically connected to the photoelectric sensor. When the upper template 21 is displaced downward to a certain distance, the prompt light 412 lights up, thereby informing the staff that the mold is in place to ensure the shaping quality of the product.
