Description

Technical Field

[0001] This utility model relates to the field of casting technology, and in particular to an adjustable spacing casting ejection device. Background Technology

[0002] In the casting process, the casting ejection device is a key piece of equipment for separating the casting from the mold. It uses multiple ejector pins located below the mold to move upwards and eject the solidified casting from the cavity for easy removal.

[0003] In existing technology, these ejector pins are mounted on a fixed ejector plate. The position of each ejector pin is pre-designed and fixed according to the structure of the specific mold and casting. This design is effective for mass production of a single product. However, with the diversification of market demand, factories need to frequently change molds to produce castings of different specifications or shapes. Different castings have different optimal ejection points, which requires the relative positions between ejector pins to also change accordingly.

[0004] For the aforementioned fixed-structure ejection device, it is impossible to meet the need for flexible spacing adjustment. Once the product needs to be changed, the entire ejection plate assembly must be replaced. This results in long mold replacement cycles, high costs, and cumbersome operations, which seriously affects production efficiency and equipment versatility.

[0005] Therefore, this utility model proposes an adjustable spacing casting ejection device to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems existing in the casting demolding and ejection device, such as the fixed position of the ejector pin, the inability to flexibly adjust the spacing, and the cumbersome and inefficient process of replacing and maintaining the ejector pin, this utility model aims to provide an adjustable spacing casting demolding and ejection device with an improved structure that can effectively solve the above problems.

[0007] This utility model provides an adjustable spacing casting demolding and ejection device, including: a base, a longitudinal slide rail fixedly connected to the base, a slider one slidably connected to the longitudinal slide rail, a fixing plate fixedly connected to the top of slider one, a transverse slide rail fixedly connected to the fixing plate, a slider two slidably connected to the transverse slide rail, and a connecting plate fixedly connected to the top of slider two.

[0008] The adjustable spacing casting ejection device also includes a top column, the bottom of which is fixedly connected to a frustum and a locking mechanism.

[0009] The locking mechanism includes a fixed cover rotatably connected to the connecting plate. The fixed cover is used to open and close the frustum. The locking mechanism also has a connecting block. A limiting post and a locking rod that move synchronously are fixedly connected to the connecting block. The limiting post is slidably disposed on the fixed cover, and the locking rod is also slidably disposed on the fixed cover. The locking rod is used to lock the fixed cover in the closed state in a pluggable manner. The fixed cover's enclosure of the frustum and the locking rod's locking together achieve rapid fixation of the top post.

[0010] Preferably, the fixing plates are fixedly connected to the top of the opposite side of the two sliders by bolts and nuts, which provides a stable and reliable installation platform for the transverse slide rail.

[0011] Preferably, both slider one and slider two are provided with threaded holes. The adjustable spacing casting demolding and ejection device also includes a rotating column. The rotating column passes through the threaded hole and is screwed in so that its end abuts against the inner wall of the longitudinal slide rail or the transverse slide rail. The friction generated by the end abuts is used to fix the position of slider one and slider two, ensuring the stability of the position after adjustment.

[0012] Preferably, the limiting post slides on the left inner wall of the fixed cover; the locking rod slides on the right inner wall of the fixed cover, and the limiting post and the locking rod are fixedly connected by a connecting block to ensure that the pin assembly can move synchronously.

[0013] Preferably, the bottom end of the limiting post is provided with a protrusion. The protrusion is used to abut against the internal structure of the fixing cover when the connecting block is manually pulled up, thereby providing a physical limit to prevent the pin assembly from moving up too much and coming out, and effectively limiting the lifting distance.

[0014] Preferably, the bottom end of the limiting post is connected to an elastic component. The elastic component provides an automatic restoring force when the operator loosens the connecting block, automatically pulling the limiting post and locking rod back to their original positions, so that the locking rod can be reinserted into the fixed cover to achieve locking, thereby improving the convenience of operation and the reliability of locking.

[0015] Preferably, in the installed state, the bottom of the frustum is tightly attached to the top of the connecting plate, and the fixing cover completely covers the frustum in the closed state. The stability of the top column under force during the ejection operation is ensured by the cooperation between the conical side of the frustum and the inner cavity surface of the fixing cover.

[0016] Preferably, the fixed cover rotates around its pivot point where it is rotatably connected to the connecting plate. This design of rotating around the pivot point allows the fixed cover to be easily flipped upwards after the locking rod slides out of the fixed cover to unlock, thereby fully opening the fixed cover and providing sufficient operating space for taking out and placing the top post and the truncated pyramid.

[0017] This utility model has the following beneficial effects:

[0018] 1. This utility model solves the problem that the fixed spacing of the ejector pins in the prior art cannot adapt to the production needs of different castings by setting a longitudinal slide rail, a slider one, a transverse slide rail and a slider two, and making them slide together. It realizes that the position of a single ejector pin can be easily adjusted arbitrarily in the horizontal plane, thereby flexibly changing the spacing of the ejector pins and improving the applicability and versatility of the device.

[0019] 2. This utility model solves the problems of complex disassembly and assembly of the top column in the prior art, which requires tools, is time-consuming and labor-intensive, and has low maintenance efficiency, by setting a locking mechanism consisting of a fixed cover, a frustum and a pin assembly. It enables the fixed cover to be opened quickly by hand and the top column to be removed or installed, realizing the rapid replacement and maintenance of the top column, and greatly improving the convenience of operation and work efficiency.

[0020] 3. This utility model solves the safety hazard caused by incomplete locking or forgetting to lock in manual locking devices by setting an elastic component on the limiting post of the locking mechanism. It realizes automatic reset and locking after the fixed cover is closed, simplifies the operation steps, ensures the reliability of locking, and improves the safety and stability of the device.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] Example:

[0029] Please refer to Figures 1 to 4 This utility model provides an adjustable spacing casting ejection device, which aims to solve the problems of fixed position of ejection device 203, poor applicability, and complicated replacement and maintenance of ejection device 203, and low efficiency in the prior art.

[0030] Please refer to Figure 1 and Figure 2 The adjustable spacing casting demolding and ejection device includes a base 1, a longitudinal slide rail 3 fixedly connected to the base 1, a slider 4 slidably connected to the longitudinal slide rail 3, a fixed plate 5 fixedly connected to the top of the slider 4, a transverse slide rail 6 fixedly connected to the fixed plate 5, a slider 7 slidably connected to the transverse slide rail 6, and a connecting plate 8 fixedly connected to the top of the slider 7. Through the dual-axis cooperation of the longitudinal slide rail 3 and the transverse slide rail 6, an adjustable horizontal moving platform is formed. The connecting plate 8 is provided with a top column 203 and a locking mechanism 2 for quick installation and removal of the top column 203.

[0031] Please refer to Figure 2 , Figure 3 and Figure 4 The bottom of the top column 203 is fixedly connected to a frustum 202. The locking mechanism 2 includes a fixed cover 201 rotatably connected to the connecting plate 8. The fixed cover 201 is used to open and close to wrap the frustum 202. The locking mechanism 2 also includes a connecting block 205. A limit post 204 and a locking rod 206 are fixedly connected to the connecting block 205. The limit post 204 is slidably disposed on the fixed cover 201, and the locking rod 206 is also slidably disposed on the fixed cover 201. When the fixed cover 201 closes to wrap the frustum 202, the locking rod 206 can be plugged and unplugged to lock the fixed cover 201, thereby firmly installing the top column 203 on the connecting plate 8 through the frustum 202.

[0032] Please refer to Figure 1 and Figure 2Both slider 4 and slider 7 are provided with threaded holes 10. The adjustable spacing casting ejection device also includes a rotating column 11. The rotating column 11 passes through the threaded hole 10 of slider 4 and is screwed in so that the end of the rotating column 11 abuts against the inner wall of the longitudinal slide rail 3. The rotating column 11 passes through the threaded hole 10 of slider 7 and is screwed in so that the end of the rotating column 11 abuts against the inner wall of the transverse slide rail 6. By tightening the rotating column 11, the friction generated by the end abuts is used to firmly fix slider 4 and slider 7 to any adjustable position on the longitudinal slide rail 3 and transverse slide rail 6, respectively, realizing the position locking function in the Y-axis direction and the X-axis direction.

[0033] Furthermore, in the assembled state, the fixing plates 5 are fixedly connected to the top of the opposite sides of the two sliders 4 by bolts 9 and nuts. The transverse slide rail 6 is fixedly installed on the fixing plates 5, and the front and rear sides of the bottom of the connecting plate 8 are fixedly connected to the front and rear sides of the top of the slider 7. This structure ensures that when the slider 4 slides along the longitudinal slide rail 3, it can drive the fixing plate 5, the transverse slide rail 6, the slider 7, the connecting plate 8 and the locking mechanism 2 above it to move in the Y-axis direction. When the slider 7 slides along the transverse slide rail 6, it can drive the connecting plate 8 and the locking mechanism 2 above it to move in the X-axis direction.

[0034] As a preferred embodiment, please refer to Figure 3 and Figure 4 The limiting post 204 slides on the left inner wall of the fixed cover 201, and the locking rod 206 slides on the right inner wall of the fixed cover 201. The limiting post 204 and the locking rod 206 are fixedly connected by the connecting block 205, thus forming a synchronous sliding pin assembly.

[0035] In another preferred embodiment, in order to limit the stroke of the pin assembly and automatically reset it, the bottom end of the limiting post 204 is integrally formed with a protrusion. When the connecting block 205 is manually pulled up, the protrusion will abut against the internal limiting structure of the fixing cover 201, thereby limiting the upward distance of the limiting post 204 and preventing the pin assembly from coming out. At the same time, the bottom end of the limiting post 204 is also connected to an elastic component. When the connecting block 205 is released, the elastic force of the elastic component will automatically pull the limiting post 204 and the locking rod 206 back to their original positions, thereby achieving automatic locking.

[0036] As another preferred embodiment, in order to ensure the stability of the top column 203 installation, during installation, the bottom of the frustum 202 is pressed against the top of the connecting plate 8, and then the fixing cover 201 is closed so that it completely covers the frustum 202 in the closed state. The conical side of the frustum 202 cooperates with the inner cavity surface of the fixing cover 201, thereby achieving both radial and axial fixation of the top column 203.

[0037] As another preferred embodiment, in order to achieve convenient opening and closing of the fixed cover 201, the fixed cover 201 rotates around the position where it is rotatably connected to the connecting plate 8. When the locking rod 206 is completely slid out of the locking position of the fixed cover 201 by pulling up the connecting block 205, the fixed cover 201 can be flipped upward around the axis to completely open the fixed cover 201 for the installation or removal of the top column 203.

[0038] Working principle: When the horizontal position of the top column 203 needs to be adjusted, first rotate the corresponding rotating column 11 in the opposite direction so that the end of the rotating column 11 disengages from the inner wall of the longitudinal slide rail 3 or the transverse slide rail 6, thereby unlocking the slider 1 4 or the slider 2 7; if the Y-axis position needs to be adjusted, manually move the slider 1 4, which will drive the upper fixed plate 5, the transverse slide rail 6, the slider 2 7, the connecting plate 8, and the entire locking mechanism 2 to slide along the longitudinal slide rail 3; if the X-axis position needs to be adjusted, manually move the slider 2 7, which will drive the upper connecting plate 8 and the locking mechanism 2 to slide along the transverse slide rail 6; after adjusting to the desired position, tighten the rotating column 11 again so that the end of the tightened rotating column 11 abuts against the inner wall of the slide rail again, using friction to firmly lock the slider 1 4 and the slider 2 7.

[0039] When it is necessary to disassemble or replace the top post 203, operate the locking mechanism 2 and manually pull the connecting block 205 upward. The connecting block 205 drives the fixedly connected limiting post 204 and locking rod 206 to slide upward synchronously until the locking rod 206 completely slides out of the right inner wall of the fixed cover 201. At this time, the locking state of the fixed cover 201 is released. The upward pulling process is limited by the protrusion at the bottom of the limiting post 204. The unlocked fixed cover 201 is rotated around the position where it is rotatably connected to the connecting plate 8. Flip it upwards to fully expose the frustum 202. At this point, the top post 203, along with the frustum 202, can be removed from the connecting plate 8. During installation, reverse the process: place the bottom of the frustum 202 against the top of the connecting plate 8, close the fixing cover 201 to completely cover the frustum 202, and loosen the connecting block 205. The elastic component at the bottom of the limiting post 204 will automatically pull the pin assembly back to its original position, allowing the locking rod 206 to re-insert into the inner wall of the fixing cover 201, achieving rapid and automatic locking.
