Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of molds, and specifically, to a mold with a splicing structure. Background Art
[0002] A mold is an important tool for shaping articles in industrial production. It endows raw materials with specific shapes and dimensions through specific shapes and structures. There are various types of molds, such as injection molds, stamping molds, die-casting molds, etc. During the manufacturing process, the accuracy of the mold is crucial, directly affecting the quality and performance of the product. High-quality molds can ensure precise product dimensions, smooth surfaces, and stable structures. The design and manufacturing of molds require professional technologies and experiences, involving multiple fields such as materials science, machining, and CAD / CAM technology.
[0003] The use of molds improves production efficiency and enables large-scale and standardized production. It is widely used in industries such as automobiles, electronics, household appliances, and plastic products, making important contributions to the development of modern industry.
[0004] When the existing molds are demolded, usually part of the product adheres to the mold, increasing the difficulty of demolding. Even during demolding, due to excessive local stress, the products formed by the mold may be damaged. Summary of the Utility Model
[0005] In order to overcome the above technical problems, the utility model provides a mold with a splicing structure to improve the problem of demolding adhesion.
[0006] To achieve the above purpose, the utility model proposes a mold with a splicing structure, including a shell frame composed of a bottom plate and side plates with a hollow structure. At the corresponding positions of the hollow structure on the outer wall of the bottom plate, hinges fixedly connected to the bottom plate are installed. It also includes a movable shell plate covering the hollow structure, and the movable shell plate is connected to the hinge.
[0007] The mold is set as a shell frame composed of a bottom plate and side plates with a hollow structure, enabling the mold to have an overall skeleton structure. The hollow structure is supplemented by a movable shell plate, and the movable shell plate is connected to the shell frame through a hinge to form a complete mold shell. When needed, the movable shell plate can be opened separately, enabling the products formed by the mold to be partially demolded first. The partial demolding location is usually the part where the product adheres most tightly to the mold. Therefore, during demolding, the movable shell plate is opened first. Since the area covered by the movable shell plate is small, the adhesion force during demolding is small, making it easier for the product to be partially separated. Once the most difficult part to separate from the mold is separated, the remaining parts are easily detached, making the demolding process simple and improving the demolding efficiency.
[0008] Preferably, there are a plurality of the hollow structures, and a plurality of hinges are respectively installed at each hollow structure, as well as a movable shell plate connected to each hinge.
[0009] By providing a plurality of hinges and installing a plurality of movable shell plates, when the product is demolded, each movable shell plate is separated first, and the movable shell plates are opened in sequence. Each time a movable shell plate is opened, the adhesion force is relatively small. By opening each movable shell plate in sequence, most of the molded product has been separated from the mold, and the remaining part is easier to separate. Therefore, the molded product is not easily damaged when demolded, and the demolding efficiency is improved.
[0010] Preferably, a baffle for preventing material leakage is provided on one side of the outer wall of the movable shell plate.
[0011] The function of setting the baffle is to block the material that oozes out due to pressure, prevent the material from leaking through the gaps between the movable shell plates, and ensure that the overall material of the molded product does not flow out.
[0012] Preferably, a groove is formed on the side wall of the movable shell plate, an elastic member is installed in the groove, and a top plate that can be elastically received into the groove is connected to one side of the elastic member near the outer opening of the groove.
[0013] The functions of setting the groove, the elastic member and the top plate are to play a sealing role between the movable shell plates, and further to hold the top plate against the elastic member, thereby blocking the gaps between the movable shell plates and preventing material leakage.
[0014] Preferably, the cross-section of the top plate perpendicular to the length direction is arc-shaped.
[0015] The top plate is set to have a curved structure, which can fit more closely with the gap between the movable shell plates. Even if there is a slight deviation in the angle, the arc-shaped structure can be timely fitted in a rolling state.
[0016] Preferably, a plurality of recessed portions that are recessed into the interior of the movable shell plate are formed on the outer wall of the movable shell plate.
[0017] By providing a plurality of recessed portions on the outer wall of the movable shell plate, which is equivalent to providing a plurality of pit-shaped depressions. When cooling the mold shell with water, part of the water will seep into the recessed portions, and the distance from the product in the high-temperature state inside the mold is closer, so that the internal heat can be dissipated faster. Thus, the molded product at the movable shell plate can be quickly cooled, and it can be quickly cooled and formed for easy separation.
[0018] Preferably, heat sinks are provided at intervals between the recessed portions.
[0019] Setting heat sinks between the recessed portions is also to further accelerate the heat dissipation speed and assist in cooling.
[0020] The mold with a splicing structure provided by the present utility model is provided with a movable shell plate, and the movable shell plate is hinged to the shell frame. After the internal molded product cools down, first, the movable shell plate with a smaller coverage area is opened, so that the molded product can be partially separated from the mold with the least force, and the movable shell plate is arranged at the part where the molded product is most difficult to separate. Once separated from the movable shell plate, the remaining part can be easily separated from the mold, improving the demolding efficiency and reducing the adhesion damage to the molded product.

The hollow structure 3 is supplemented by movable shell plates 5, and the movable shell plates 5 are connected to the shell frame through hinges 4 to form a complete mold shell. The movable shell plates 5 can be opened separately when needed, so that the product formed by the mold is first partially demolded. The partial demolding location is usually the part where the product adheres most tightly to the mold. Therefore, when demolding, the movable shell plates 5 are first opened. Since the area covered by the movable shell plates 5 is small, the adhesion force during demolding is relatively small, making it easier for the product to be partially separated.

Each time a movable shell plate 5 is opened, the adhesion force is relatively small. By opening each movable shell plate 5 in sequence, most of the formed product has been separated from the mold, and the remaining part is easier to separate, so that the formed product is not easily damaged during demolding, and the demolding efficiency is improved.
[0031] As shown in an embodiment of the present utility model, a baffle 6 for preventing material leakage is provided on one side of the outer wall of the movable shell plate 5.
[0032] The function of setting the baffle 6 is to block the material that oozes out due to pressure, prevent the material from leaking through the gaps between the movable shell plates 5, and play a role in ensuring that the overall material of the formed product does not flow out.
[0033] As shown in an embodiment of the present utility model, a groove 7 is formed on the side wall of the movable shell plate 5, an elastic member is installed in the groove 7, and one side of the elastic member close to the outer opening of the groove 7 is connected to a top plate 8 that can be elastically received into the groove 7.
[0034] The function of setting the groove 7, the elastic member, and the top plate 8 is to play a sealing role between the movable shell plates 5, and further to hold the top plate 8 against the elastic member, thereby blocking the gaps between the movable shell plates 5 and playing a role in preventing material leakage.
[0035] As shown in an embodiment of the present utility model, the cross-section of the top plate 8 perpendicular to the length direction is arc-shaped.
[0036] The top plate 8 is set to have a curved structure, which can fit more closely with the gaps between the movable shell plates 5. Even if there is a slight deviation in the angle, the arc-shaped structure can be timely fitted in a rolling state.
[0037] As shown in one embodiment of the present utility model, a plurality of recessed portions 9 recessed into the interior of the movable shell plate 5 are formed on the outer wall of the movable shell plate 5.
[0038] Providing a plurality of recessed portions 9 on the outer wall of the movable shell plate 5 is equivalent to providing a plurality of pit-shaped recesses. When cooling the mold shell with water, some water will seep into the recessed portions 9, and the distance to the product in the high-temperature state inside the mold is closer, enabling the internal heat to dissipate faster. Thus, the formed product at the movable shell plate 5 can be rapidly cooled, quickly cooled and formed, and facilitated to be separated.
[0039] As shown in one embodiment of the present utility model, heat sinks 10 are provided at intervals between the recessed portions 9.

And the movable shell plate 5 is arranged at the part where the formed product is most difficult to be separated. Once separated from the movable shell plate 5, the remaining parts can be easily separated from the mold, improving the demolding efficiency and reducing the adhesion damage to the formed product.
