Description

Technical Field

[0001] This utility model relates to the field of automatic door opening and demolding technology, and in particular to an automatic door opening and demolding device. Background Technology

[0002] Molds are essential tools in industrial production used for shaping, casting, or stamping workpieces, and are widely used in machinery manufacturing, automotive, electronics, and daily necessities industries. Through specific cavity structures, they mold materials into desired shapes, offering advantages such as high precision, high efficiency, and mass production capabilities. Molds come in various types, including injection molds, die-casting molds, and stamping dies, and their performance directly affects workpiece quality and production efficiency.

[0003] Currently, existing molds generally lack efficient and stable demolding mechanisms during the molding process, with demolding operations mainly relying on manual labor or simple ejection devices. Manual demolding requires frequent operator intervention, increasing labor intensity and affecting production cycle time. While ejection demolding can achieve a certain degree of automation, uneven force on the ejector pins or plates during workpiece ejection can easily lead to workpiece deformation or surface damage, especially for complex or thin-walled workpieces. Furthermore, traditional demolding methods are difficult to adapt to the rapid switching requirements of multiple workpiece specifications, restricting production flexibility.

[0004] Based on the aforementioned technologies, the applicant believes that manual demolding is inefficient, difficult to meet the requirements of mass production, and poses safety hazards; while ejection demolding is prone to causing scratches, deformation, and other defects to the workpiece due to mechanical impact, affecting the product qualification rate. In response to the above problems, we have launched an automatic door opening demolding device. Utility Model Content

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An automatic door opening and demolding device includes a base, a base fixedly connected to the top of the base, and a demolding mechanism provided on the top of the base. The demolding mechanism includes a demolding component and a die-casting component, which cooperate with each other. The demolding component includes a mold-closing base, which is fixedly connected to the top of the base. The top of the base has symmetrically formed T-shaped grooves.

[0008] The demolding mechanism is more efficient than manual demolding and is more suitable for mass production. At the same time, compared with ejection demolding, it avoids defects such as scratches and deformation of the workpiece. The structure is simple and highly practical.

[0011] In a preferred embodiment, storage boxes are symmetrically slidably connected to the front of the base, and pull handles are fixedly connected to the front of both storage boxes.

[0012] The sliding storage box on the base facilitates the collection of workpieces after demolding, and the pull handle makes it easy for operators to pick up and put down the workpieces, thus improving production efficiency.

[0013] In a preferred embodiment, the size of the T-shaped slider matches the size of the T-shaped groove, and the T-shaped slider and the T-shaped groove are used in conjunction with each other.

[0014] The T-shaped slider and T-slot are matched in size to ensure smooth sliding without deviation, thereby improving the stability and service life of the mold.

[0015] In a preferred embodiment, a controller is fixedly connected to the outer side of the base.

[0016] The controller is integrated on the outside of the base, making it easy for operators to control the equipment and achieve automated production management.

[0017] In a preferred embodiment, the hydraulic cylinder is electrically connected to the controller.

[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0029] The automatic door opening and demolding device disclosed in this utility model is mainly used in automatic door opening and demolding scenarios.

[0030] Reference Figure 1 - Figure 5 An automatic door opening and demolding device includes a base 1, a base 2 fixedly connected to the top of the base 1, a demolding mechanism on the top of the base 1, the demolding mechanism including a demolding component and a die-casting component, the demolding component and the die-casting component working together, the demolding component including a mold-closing base 3, the mold-closing base 3 fixedly connected to the top of the base 2, T-shaped grooves 41 symmetrically opened on the top of the base 2, T-shaped sliders 42 symmetrically slidably connected inside the two T-shaped grooves 41, side plates 43 fixedly connected to the top of the two T-shaped sliders 42 on the same side, slots 46 fixedly connected to the side of the two side plates 43 that are close to each other, the slots 46 and the mold-closing base 3 working together, springs 44 fixedly connected inside the two T-shaped grooves 41, the springs 44 fixedly connected to the T-shaped sliders 42, and a baffle plate 45 fixedly connected to the top of the two T-shaped grooves 41. The die-casting assembly includes a support frame 57, which is fixedly connected to the top of the base 1. A hydraulic cylinder 51 is fixedly connected to the top of the support frame 57. An upper mold 56 is fixedly connected to the telescopic end of the hydraulic cylinder 51. A connecting frame 52 is fixedly connected to the outside of the hydraulic cylinder 51. Slanted sliders 53 are symmetrically fixedly connected to the two side plates 43 on their opposite sides. An inclined slide groove 54 is opened inside the inclined slide groove 54. A sliding column 55 is slidably connected inside the inclined slide groove 54. The sliding column 55 is fixedly connected to the connecting frame 52.

[0031] In this embodiment: When the hydraulic cylinder 51 is activated, its telescopic end drives the upper mold 56 to press down, while the sliding column 55 fixed on the upper mold 56 slides downward along the inclined slide groove 54 of the inclined slide block 53. Due to the inclined angle design of the inclined slide groove 54, the downward movement of the sliding column 55 pushes the inclined slide blocks 53 on both sides and the connected side plates 43 to move towards the center along the T-shaped groove 41, so that the slots 46 on the side plates 43 fit tightly with the mold base 3 to form a complete molding cavity. At this time, the upper mold 56 continues to press down, completely fitting with the molding mold, completing the die casting process. After molding is completed, the hydraulic cylinder 51 retracts, causing the upper mold 56 to rise. The slide column 55 slides in the opposite direction along the inclined slide groove 54. Under the restoring force of the spring 44, it pushes the side plate 43 to move outward along the T-shaped groove 41, causing the slot 46 to separate from the mold base 3, thus realizing the automatic opening and demolding of the mold. The demolding mechanism is more efficient than manual demolding and is more suitable for the needs of mass production. At the same time, compared with ejection demolding, it avoids scratches, deformation and other defects on the workpiece. The structure is simple and highly practical.

[0032] In the above technical solutions, considering the low efficiency of manual demolding, which is difficult to meet the requirements of mass production and poses safety hazards; and the problem that ejection demolding can easily cause scratches, deformation and other defects to the workpiece due to mechanical impact, affecting the product qualification rate, the specific operation is as follows to solve these problems:

[0033] Reference Figure 1 - Figure 5 In a preferred embodiment, storage boxes 6 are symmetrically slidably connected to the front of the base 1, and pull handles 7 are fixedly connected to the front of each of the two storage boxes 6. The size of the T-shaped slider 42 matches the size of the T-shaped groove 41, and the T-shaped slider 42 and T-shaped groove 41 cooperate with each other. A controller 8 is fixedly connected to the outside of the base 1. The hydraulic cylinder 51 is electrically connected to the controller 8.

[0034] In this embodiment, the storage box 6, which slides on the base 1, facilitates the collection of workpieces after demolding. The pull handle 7 allows operators to easily pick up and put down the workpieces, improving production efficiency. The T-shaped slider 42 and T-shaped groove 41 are dimensionally matched to ensure smooth sliding without deviation, improving the stability and service life of the mold. The controller 8 is integrated on the outside of the base 1, allowing operators to easily control the equipment and achieve automated production management. The hydraulic cylinder 51 is electrically connected to the controller 8, enabling precise control of the die-casting and demolding processes, improving production efficiency and consistency.

[0035] Working principle: When the hydraulic cylinder 51 is activated, its telescopic end drives the upper mold 56 to press down, while the sliding column 55 fixed on the upper mold 56 slides downward along the inclined slide groove 54 of the inclined slide block 53. Due to the inclined angle design of the inclined slide groove 54, the downward movement of the sliding column 55 pushes the inclined slide blocks 53 on both sides and the connected side plates 43 to move towards the center along the T-shaped groove 41, so that the slots 46 on the side plates 43 fit tightly with the mold base 3, forming a complete molding cavity. At this time, the upper mold 56 continues to press down, completely fitting with the molding mold, completing the die casting molding process. After molding is completed, the hydraulic cylinder 51 retracts, driving the upper mold 56 to rise, and the sliding column 55 slides in the opposite direction along the inclined slide groove 54. Under the restoring force of the spring 44, it pushes the side plates 43 to move outward along the T-shaped groove 41, causing the slots 46 to separate from the mold base 3, realizing the automatic opening and demolding of the mold. Throughout the process, the precise fit between the T-shaped slider 42 and the T-shaped groove 41 ensures the stability of the side plate 43's movement, while the storage box 6 stores the demolded workpiece. This mechanism, through the synergistic effect of hydraulic drive and mechanical linkage, achieves an efficient and stable automated demolding process, which not only improves production efficiency but also avoids the potential damage to the workpiece caused by traditional ejection demolding.

[0036] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
