Description

Technical Field

[0001] This utility model relates to the field of molds, and in particular to a rapid prototyping mold for complex shaped parts. Background Technology

[0002] Complex shape molds are tools used to manufacture products with intricate structures and complex geometries. They are typically made of high-strength metal materials, such as alloy steel, to ensure stable performance and a long service life in harsh processing environments such as high temperature and high pressure. Their internal structure is extremely sophisticated; through precise calculations and advanced manufacturing processes, they can accurately form various complex shapes, including multi-curved surfaces, deep cavities, and thin-walled structures, meeting the diverse shape and functional requirements of different products.

[0003] Patent publication number CN220841141U discloses a mold for molding complex-shaped plastic products, including a lower box and an upper box. Connecting plates are fixedly connected to the side walls of the lower and upper boxes, and bolts are threaded to the joints of multiple connecting plates. A lower mold is located inside the lower box, and an upper mold is located inside the upper box. An air pump is fixedly connected to the side wall of the lower box, and two air guide pipes are fixedly connected to the side wall of the air pump. The air pump provided by this invention can extend gas through the air guide pipes and hoses to the interior of a one-way valve. Under the influence of air pressure, the lower and upper molds slide along the inner wall of the guide groove via a guide block, allowing gas to fill the gap between the lower and upper molds, creating a gap between the molds for easier subsequent demolding.

[0004] However, the molds in the aforementioned patents are connected by bolts, so multiple bolts need to be removed during demolding, which is not convenient for quick demolding and reduces production efficiency. In contrast, the mechanical or hydraulic demolding commonly used in the prior art requires pre-set demolding elements inside the mold. When the inner wall of the mold has a complex shape, it is not easy to completely fit the demolding structure with the inner wall of the mold, which can easily lead to shape or size errors in the produced parts. In addition, the aforementioned patents do not have a structure for sealing. When the mold is used for a long time, the wear of the mold itself can cause the two molds to not close tightly, which can easily lead to leakage of injection molding material. Utility Model Content

[0005] The present invention aims to solve the technical problem mentioned in the background section by providing a rapid prototyping mold for complex-shaped parts.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0028] This application designs a rapid prototyping mold for complex-shaped parts, as shown in the attached figure. Figure 1-3 As shown, it includes a base 1, a slider 7, a slide 12, a first half mold 2, a second half mold 3, a demolding assembly, and a sealing assembly;

[0029] The first half mold 2 is fixedly connected to the top of the base 1. The slide groove 12 is opened on the top of the base 1 away from the first half mold 2. The slider 7 is fixedly connected to the bottom of the second half mold 3. The slider 7 is movably connected to the slide groove 12.

[0030] The demolding assembly is located on the front of the first half mold 2, and the sealing assembly is located on the outside of the second half mold 3 on the side away from the first half mold 2.

[0031] In the above embodiments, the inner walls of the first half mold 2 and the second half mold 3 are processed into corresponding shapes according to the shape of the part to be produced. After the first half mold 2 and the second half mold 3 are closed, the first half mold 2 and the second half mold 3 are covered by the external upper mold to perform the part forming work.

[0032] Furthermore, the demolding assembly includes a lead screw 6, a groove plate 8, a locking rod 9, a slide rail 10, a connecting shaft 11, a round hole 15, and a straight groove 16;

[0033] The lead screw 6 is installed on the outside of the base 1, and the slot plate 8 is fixedly connected to the nut part of the lead screw 6;

[0034] The clamping rod 9 is fixedly connected to the second half mold 3, and the clamping rod 9 is movably connected inside the slot plate 8;

[0035] The slide rail 10 is fixedly connected to the top of the first half mold 2. The round hole 15 is opened on the side of the slide rail 10 close to the second half mold 3. The straight groove 16 is opened on the side of the slide rail 10 away from the second half mold 3. The straight groove 16 is connected to the round hole 15.

[0036] The connecting shaft 11 is fixedly connected to the top of the second half mold 3. The cross-section of the connecting shaft 11 is a rounded rectangle. The distance between the two straight sides of the rounded rectangle is the same as the width of the straight groove 16, and the radius of the arc side is the same as that of the circular hole 15.

[0037] In the above embodiments, the lead screw 6 is an electric lead screw 6. The lead screw 6 pushes the groove plate 8 to move. The groove plate 8 drives the clamping rod 9 and the second half mold 3 to move outward. The second half mold 3 drives the connecting shaft 11 to move outward along the straight groove 16. When it moves into the inside of the round hole 15, the groove plate 8 pushes the second half mold 3 to rotate upward around the connecting shaft 11, thereby opening the second half mold 3 and facilitating demolding.

[0038] Furthermore, the sealing assembly includes a housing 4, a connecting rod 5, a push plate 13, and a spring 14;

[0039] The connecting rod 5 is rotatably connected to the side of the base 1 near the second half mold 3, and the sleeve 4 is fixedly connected to the connecting rod 5. The connecting rod 5 is driven by a motor.

[0040] Spring 14 is installed inside housing 4, and push plate 13 is fixedly connected to the other end of spring 14.

[0041] In the above embodiments, the elastic force provided by the spring 14 causes the push plate 13 to always press against the second half mold 3, so that the second half mold 3 and the first half mold 2 remain tightly closed under the elastic force of the spring 14, thereby avoiding the formation of gaps between the first half mold 2 and the second half mold 3 that could lead to leakage of injection molding material.

[0042] Working principle: After the part is formed, the motor rotates the connecting rod 5, causing the push plate 13 to separate from the second half mold 3. Then, the lead screw 6 pushes the groove plate 8 to move. The groove plate 8 drives the clamping rod 9 and the second half mold 3 to move outward. The second half mold 3 drives the connecting shaft 11 to move outward along the straight groove 16. When it moves into the round hole 15, the groove plate 8 pushes the second half mold 3 to rotate upward around the connecting shaft 11, thereby opening the second half mold 3 and exposing part of the part. At this time, the part can be taken out by external clamps or other equipment. Demolding can be achieved without setting push rods or other mechanical structures inside the part, which is convenient for use.

[0043] The above embodiments are only some embodiments of this utility model, not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the protection scope of this utility model.
