Description

Technical Field

[0001] The invention relates to a casting mold for a camera steering support seat, and belongs to the technical field of casting molds. Background Art

[0002] A casting mold, also known as a casting die, is a mold that is pre-formed with other easily moldable materials to achieve the desired part's structural shape. The mold is then placed in a sand mold, creating a cavity with the same dimensions as the part. A fluid liquid is then poured into this cavity, which, after cooling and solidifying, forms a part with the exact same shape and structure as the mold. Machined casting molds also exist, enabling precise shaping of the casting cavity. This is achieved by pouring casting liquid into the cavity, followed by cooling and forming.

[0003] There is currently a camera steering support seat, which includes a disc-shaped main body, an axial boss on one side of the disc-shaped main body, an annular outer edge on the other side, and a plurality of circumferentially evenly distributed matching bosses on the outer periphery of the disc-shaped main body. An inner groove position is provided on any of the matching bosses. It is difficult to demold after casting, and it is difficult to achieve complete casting.

[0004] When casting it with a traditional casting mold, the full-size casting of the matching boss is generally performed. After the boss is formed, the inner groove on the matching boss is machined, which undoubtedly prolongs the product production cycle and increases the production cost.

[0005] In addition, the connection part between the casting mold and the casting cavity is an axial boss. Therefore, when the product is detached after the mold is separated, the casting part needs to be hard separated, that is, the separation of the casting mouth and the product connection part. There is a large pulling force, and the disc-shaped main body will produce a certain degree of deformation under the action of traction. Therefore, the annular outer edge will be subjected to a large force, which is easy to deform and cause product defects. Summary of the Invention

[0006] The purpose of the present invention is to solve the deficiencies of the above-mentioned prior art.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0030] The present application will be further described in detail below with reference to the accompanying drawings and examples. It will be understood that the specific embodiments described herein are intended only to explain the relevant inventions and are not intended to limit the inventions. It should also be noted that, for ease of description, only portions relevant to the relevant inventions are shown in the accompanying drawings. It should be noted that, unless there is a conflict, the embodiments and features in the embodiments of this application may be combined with each other.

[0031] The present invention provides a casting mold for a camera steering support seat, such as Figure 4 As shown, the camera steering support seat 100 includes a disc-shaped main body 110, one side of the disc-shaped main body 110 is provided with an axial boss 120, the other side is provided with an annular outer edge 130, the outer periphery of the disc-shaped main body 110 is provided with a plurality of circumferentially evenly distributed matching bosses 140, and any matching boss is provided with an inner groove position 150.

[0032] The structure of the camera steering support seat 100 is relatively complex, and the traditional casting mold has relatively poor molding accuracy, especially when rejecting the product, which will cause product deformation and affect the product qualification rate.

[0033] This case raises the following Figures 1 to 3 The casting mold shown includes a first casting mold base 1 and a second casting mold base 2 with relative opening and closing displacements.

[0034] The first casting mold base 1 is provided with a fixed mold core 3, and the fixed mold core 3 is provided with a disc-shaped main body molding cavity 30. The disc-shaped main body molding cavity 30 is provided with an inner hole column 31 for forming the inner channel of the axial boss and an annular outer edge cavity 32 for forming the annular outer edge. The disc-shaped main body molding cavity is connected to a casting port 4.

[0035] The second casting mold base 2 is provided with a disc-shaped main body matching cavity 5 and a number of movable mold cores 6 arranged on the outer periphery of the disc-shaped main body matching cavity and corresponding to the matching bosses. Any movable mold core 6 is provided with a model end 60 with horizontal linear displacement, and the model end is provided with a matching boss forming part 61 for matching boss forming, and the matching boss forming part is provided with an inner groove forming block 62 for forming the inner groove position.

[0036] Specific implementation process and principle description:

[0037] The mold closing direction is designed along the axial direction of the axial boss 120 to meet the linear displacement cooperation of the movable mold core 6, so as to complete the mold closing and molding of the casting chamber. The casting chamber is complete, and the cooperation of the model end 60 is used to realize the precise molding of the matching boss and the inner groove. At the same time, the disc-shaped main body molding cavity 30 and the disc-shaped main body matching cavity 5 are spliced ​​together, and relative splicing guidance with the movable mold core can be realized, so that the mold closing position is accurate.

[0038] In addition, the casting port 4 is connected to the disc-shaped main body molding cavity, so that the casting liquid is poured into one side of the axial boss 120, so that its structural strength is reliable and the overall molding integrity is guaranteed.

[0039] In a specific embodiment, the fixed mold core 3 is provided with a mold closing guide groove 33 corresponding to the movable mold core one by one, and the movable mold core 6 includes a movable mold slider 7 and a guide matching part 70 arranged on the movable mold slider for matching with the mold closing guide groove, and the model end is arranged on the guide matching part.

[0040] The movable mold slider 7 is used to realize linear drive of the guide matching part 70, and the guide matching part 70 can realize stable matching and guidance with the mold closing guide groove 33, so that the mold is closed tightly and the burr phenomenon that may be caused by exhaust is reduced.

[0041] In a specific embodiment, the movable mold slider 7 is slidingly connected to the second casting mold base, the movable mold slider is provided with an inclined guide groove 71, and the first casting mold base is provided with an inclined guide column 72 that is transmission-connected with the inclined guide groove.

[0042] That is, the inclined guide pillars 72 cooperate with the inclined guide grooves 71 to realize automatic displacement conversion in the mold closing state, while satisfying the linkage and coordinated driving of multiple movable mold slides 7, and the mold opening and closing are smooth, efficient and stable.

[0043] In a specific embodiment, the guide fitting portion 70 is detachably disposed on the movable mold slider.

[0044] Meet different changeover requirements and realize free combination and application of multiple products.

[0045] In a specific embodiment, a plurality of exhaust limiting grooves 320 are provided on the outer periphery of the annular outer cavity 32 .

[0046] Specifically, the annular outer edge 130 is relatively thin and has a concave-convex structure thereon. Therefore, during casting, the annular outer edge 130 is prone to lack of meat. On the other hand, during demolding, the casting port and the workpiece need to be pulled apart, and the annular outer edge is easily deformed and damaged by the pulling force.

[0047] To address this situation, the exhaust limit groove 320 is designed to achieve exhaust coordination, so that the annular outer edge 130 is completely formed. At the same time, the exhaust limit groove 320 forms a pile body on the molded part, which reduces the deformation of the annular outer edge 130 during demolding and pulling, thereby ensuring the product qualification rate.

[0048] In a specific embodiment, the second casting mold base 2 is provided with an exhaust portion 20 that is connected and matched with any exhaust limiting groove. Through the cooperation of the exhaust portion, the two casting mold bases 2 can achieve communication and exhaust, and the exhaust is more stable.

[0049] In one embodiment, a mating latch 160 is provided on the side of the disc-shaped body facing away from the axial boss. A mating latch groove is provided within the mating cavity of the disc-shaped body for forming the mating latch. The mating latch groove has a venting connection that communicates with the venting portion. This ensures that the annular outer edge 130 and the mating latch 160 are connected and vented, ensuring the integrity of the entire casting.

[0050] In a specific embodiment, the second casting mold base is provided with a movable mold core that is matched with the matching locking pile-shaped groove, and the model end of the movable mold core is provided with a matching block for correspondingly matching with the matching locking pile-shaped groove. The matching block and the matching locking pile-shaped groove form a casting molding chamber for the matching locking pile.

[0051] That is, a movable mold core is used to realize synchronous molding of the matching locking pile 160 and the matching boss 140, that is, the mold is separated and withdrawn, which makes it easy to realize the part removal operation.

[0052] In a specific embodiment, a template connection main seat 8 is provided on a side of the first casting mold base 1 facing away from the second casting mold base 2 , and the casting port is provided on the template connection main seat.

[0053] The first casting mold base 1 is a movable mold base with relative displacement, and the second casting mold base 2 is a fixed base. Therefore, the use of this template to connect the main base can achieve the matching between it and the first casting mold base 1, and realize the separation of casting matching and ejection. The second casting mold base 2 also has an ejection mechanism. When ejecting the workpiece, the first casting mold base 1 first realizes the separation between the casting port and the molded workpiece, and then the second casting mold base 2 is lifted and ejected, thus meeting the unloading requirements.

[0054] From the above description, we can see that the casting mold of the camera steering support seat meets the casting molding accuracy and facilitates the rejection of the casting after molding, thus ensuring product quality. The use of an interconnected exhaust matching design ensures the integrity of the product molding. At the same time, it provides structural protection during the ejection process, effectively preventing deformation and ensuring the product qualification rate. The relative position accuracy and smoothness of the mold are improved, and there is an interconnected alignment. This reduces mold costs while meeting the casting production qualification rate, and has high economic value.
