Abstract
Description
Technical Field
[0001] This utility model relates to the field of mold technology, and in particular to a slanted ejector mechanism for demolding a retaining plate. Background Technology
[0002] In existing technologies, for products with numerous undercuts and complex structures, traditional demolding methods typically employ a cap and angled ejector structure. While this structure allows for smooth demolding in situations with ample mold space, it struggles to achieve proper demolding in limited space and with complex product structures. This is because the traditional cap and angled ejector structure requires sufficient space to accommodate the movement of the angled ejector. In limited space, this movement is restricted, preventing proper demolding. Furthermore, even if demolding is achieved, the obstructed movement of the angled ejector may damage the product, affecting its quality and appearance. Therefore, there is an urgent need for an angled ejector mechanism capable of demolding complex products in confined spaces. Utility Model Content
[0003] In view of the above-mentioned shortcomings of the existing technology, the purpose of this utility model is to provide a slanted ejector mechanism for demolding protective plates, which has the advantage of being able to demold complex products in limited space.
[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0005] A slanted ejector mechanism for demolding a retaining plate, comprising:
[0006] The sloping roof has a groove on its top wall;
[0007] A spring block, the bottom wall of which is provided with a slider, the shape of which corresponds to the groove, the spring block is slidably disposed on the top wall of the inclined top through the cooperation of the slider and the groove;
[0008] A pre-tensioning component is disposed in the slide groove, one end of which is connected to the spring block and the other end of which is connected to the inclined top.
[0009] A drive mechanism, which is connected to the inclined top transmission.
[0010] Compared with the prior art, this application achieves the sliding setting of the spring block on the inclined top wall by cooperating with the sliding groove and the slider set on the spring block. This allows the spring block to move along a predetermined trajectory under the drive mechanism, thereby effectively solving the problem of large product undercut and inability to demold normally due to product structure. Secondly, the setting of the pre-tightening part ensures the stability and reliability of the spring block during the movement process, further improving demolding efficiency and quality.
[0011] As a preferred embodiment of this utility model, the inclined top is provided with a limiting block, and at least a portion of the limiting block is located within the sliding groove.
[0012] By adopting the above scheme, the design of the limiting block further enhances the structural stability and safety of the inclined ejector mechanism. By limiting the movement range of the spring block in the slide, the limiting block effectively prevents the spring block from excessive movement or misalignment during the movement, thereby ensuring the smooth progress of the demolding process.
[0013] As a preferred embodiment of this utility model, the slider is provided with a limiting groove corresponding to the limiting block.
[0014] By adopting the above solution, the cooperation between the limiting groove and the limiting block on the slider further improves the accuracy and stability of the movement of the spring block in the groove, so that the spring block can move more accurately along the predetermined trajectory during the movement, avoiding demolding failure or product damage caused by deviation or shaking.
[0015] As a preferred embodiment of this utility model, the slider is provided with a receiving hole, the pre-tightening member is located in the receiving hole, one end of the pre-tightening member is connected to the slider, and the other end is connected to the inclined top.
[0016] Using the above solution, the design of the receiving hole provides an installation space for the preload, enabling the preload to connect the spring block and the inclined top more stably, while also saving the space occupied by the installation of the preload.
[0017] As a preferred embodiment of this utility model, the pretensioning member includes a spring, one end of which is connected to the spring block and the other end of which is connected to the inclined top.
[0018] By employing the above-mentioned solution and using a spring as a preload, the spring block exhibits better elasticity and cushioning performance during the inclined ejector movement. This design not only helps the spring block smoothly disengage from the undercut surface, achieving undercut demolding, but also provides protection during mold closing, preventing the spring block from damaging the molded surface.
[0019] As a preferred embodiment of this utility model, the driving mechanism includes:
[0020] An inclined top seat, wherein a sliding groove is provided on the inclined top seat;
[0021] Universal block, the universal block being slidably mounted on the inclined top seat via the sliding groove;
[0022] An inclined push rod, one end of which is hinged to the inclined push rod, and the other end of which is connected to the universal block.
[0023] By employing the above-described scheme, the drive mechanism, through the cooperation of the angled ejector seat, universal block, and angled ejector rod, achieves precise driving and control of the angled ejector. This structure not only enables the angled ejector to move at a predetermined speed and direction but also improves the automation and efficiency of the demolding process.
[0024] The aforementioned inclined ejector mechanism for demolding guard plates has the following beneficial effects: By designing an inclined ejector mechanism that includes a slide, spring block, pre-tightening element and drive mechanism, this technical solution not only ensures the smoothness and stability of the demolding action, but also significantly improves demolding efficiency and quality. Thus, even under conditions of limited space and complex product structure, effective demolding of the undercut can be achieved, effectively avoiding product damage. Attached Figure Description

[0033] This utility model proposes a slanted ejector mechanism for demolding protective plates.
[0034] Reference Figure 1 In one embodiment of this utility model, the inclined ejector 1 mechanism for demolding a guard plate is characterized by comprising an inclined ejector 1, a spring block 3, a pre-tightening member 5, and a driving mechanism 6. The top wall of the inclined ejector 1 is provided with a groove 2; the bottom wall of the spring block 3 has a slider 4, the shape of which corresponds to the groove 2. The spring block 3 is slidably disposed on the top wall of the inclined ejector 1 through the cooperation of the slider 4 and the groove 2. In this embodiment, the axis of the groove 2 is parallel to the plane of the top wall of the inclined ejector 1. In other embodiments, the axis of the groove 2 can be designed to form a certain angle with the plane of the top wall of the inclined ejector 1 according to different actual needs. The pre-tightening member 5 is disposed in the groove 2, one end of which is connected to the spring block 3, and the other end is connected to the inclined ejector 1. The driving mechanism 6 is connected to the inclined ejector 1 in a transmission manner. By cooperating with the slider 4 set on the spring block 3 through the groove 2, the spring block 3 is slidably set on the top wall of the inclined top 1, so that the spring block 3 can move along a predetermined trajectory under the drive of the drive mechanism 6. This effectively solves the problem of large product undercut and inability to demold normally due to product structure. Secondly, the setting of the pre-tightening part 5 ensures the stability and reliability of the spring block 3 during the movement process, further improving demolding efficiency and quality.
[0035] Reference Figure 1 and Figure 2In one embodiment, to prevent the spring block 3 from detaching from the slide 2, a limiting block 7 is bolted onto the inclined ejector 1, with at least a portion of the limiting block 7 located within the slide 2. A limiting groove 8 is formed on the slider 4 corresponding to the limiting block 7, the size and shape of which correspond to the portion of the limiting block 7 located within the slide 2. The design of the limiting block 7 further enhances the structural stability and safety of the inclined ejector 1 mechanism. By limiting the movement range of the spring block 3 within the slide 2, the limiting block 7 effectively prevents excessive movement or misalignment of the spring block 3 during movement, thus ensuring a smooth demolding process. The cooperation between the limiting groove 8 on the slider 4 and the limiting block 7 further improves the accuracy and stability of the spring block 3's movement within the slide 2, enabling the spring block 3 to move more accurately along a predetermined trajectory during movement, avoiding demolding failure or product damage caused by offset or shaking.
[0036] Reference Figure 3 In one embodiment, to further reduce the volume of the inclined ejector 1 structure, a receiving hole 9 is further provided on the slider 4, and the preload 5 is located in the receiving hole 9. In this embodiment, the preload 5 includes a spring, one end of which is fixedly connected to the slider 4, and the other end is fixedly connected to the inclined ejector 1. The design of the receiving hole 9 provides an installation space for the preload 5, allowing the preload 5 to connect the spring block 3 and the inclined ejector 1 more stably, while also saving the space occupied by the installation of the preload 5. Using a spring as the preload 5 allows the spring block 3 to have better elasticity and cushioning performance during the movement of the inclined ejector 1. This design not only helps the spring block 3 to smoothly disengage from the undercut surface and achieve undercut demolding, but also plays a protective role during the mold closing process, preventing the spring block 3 from damaging the glue surface.
[0037] Reference Figure 1 In one embodiment, the drive mechanism 6 includes: a slanted ejector seat 61, a universal block 62, and a slanted ejector rod 63. The slanted ejector seat 61 has a sliding groove 64; the universal block 62 is slidably mounted on the slanted ejector seat 61 through the sliding groove 64; one end of the slanted ejector rod 63 is hinged to the slanted ejector 1, and the other end is fixedly connected to the universal block 62. The design of the drive mechanism 6, through the cooperation of the slanted ejector seat 61, the universal block 62, and the slanted ejector rod 63, achieves precise driving and control of the slanted ejector 1. This structure not only enables the slanted ejector 1 to move at a predetermined speed and direction, but also improves the automation and efficiency of the demolding process.
[0038] The working principle of this utility model is as follows:
[0039] Driven by the drive mechanism 6, the inclined ejector 1 begins to move, and the spring block 3 can move in the demolding direction under the action of the pre-tightening member 5. After the spring block 3 has moved a certain distance, it has completely disengaged from the undercut surface, realizing the demolding of the undercut. During the mold closing process, the guide inclined surface of the spring block 3 contacts the mold first, so that the spring block 3 closes the mold, thereby avoiding damage to the glue surface, until the mold closing is completed.
[0040] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
