Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for sand casting, specifically a threaded adjustable sand mold vibration spacing control device. Background Technology

[0002] The sand mold compaction spacing control device is a key auxiliary equipment in sand casting production. Its main function is to accurately control the relative spacing between the upper and lower molds during the sand mold compaction process, and to adjust the compaction of the sand mold in conjunction with the compaction mechanism. Its performance directly affects the dimensional accuracy, surface quality and internal density of the castings, and can avoid defects such as porosity and shrinkage caused by uneven sand mold compaction.

[0003] The basic structure of existing sand mold vibration spacing control devices typically includes a common flat base, a simple block support structure, an open or simple frame-type main bearing component, and a spacing adjustment component using ordinary bolts. Although some devices attempt to connect to a hydraulic auxiliary mechanism, the hydraulic interface is mostly a simple joint that is temporarily welded. This type of structure has obvious shortcomings: the lack of standardized mounting slots on the base leads to poor compatibility with external equipment; the lack of standardized hydraulic interface assembly positions on the support blocks makes it inconvenient to connect the hydraulic device and results in poor sealing; the lack of a dedicated sand mold positioning and bearing structure inside the main frame easily leads to sand mold displacement during vibration; and the spacing adjustment relies on the rough tightening of bolts without a precise adjustment and matching structure, resulting in low spacing control accuracy and low efficiency of manual adjustment. At the same time, the non-standard hydraulic connection also makes it difficult to stably control the compaction degree of the sand mold. Utility Model Content

[0004] To address the problems of poor compatibility between the base and external equipment, inconvenient access to hydraulic devices, unstable sand mold positioning, low spacing adjustment accuracy, and difficulty in stably controlling the compaction degree of existing sand mold vibration spacing control devices, this utility model provides a threaded adjustment type sand mold vibration spacing control device.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a threaded adjustable sand mold compaction spacing control device, comprising a base, a support block, a main frame, an intermediate adjusting plate, a threaded adjusting component, and a hydraulic interface component; the base is a rectangular block structure with a long mounting groove; the support block is a block structure with a hydraulic interface assembly position, and the support block is fixed to the top surface of the base; the main frame is a box-shaped frame structure with an internal inclined sand mold bearing part, and the main frame is assembled on the top surface of the support block; the intermediate adjusting plate is a rectangular flat plate structure, and the intermediate adjusting plate is located above the main frame; the threaded adjusting component is an externally threaded rod structure; the hydraulic interface component is a tubular structure with external threads; wherein, the intermediate adjusting plate is detachably connected to the main frame through the threaded adjusting component, and turning the threaded adjusting component can change the spacing between the intermediate adjusting plate and the main frame to adapt to the spacing requirements of sand mold compaction; the hydraulic interface component is assembled on the side of the support block and is used to connect an external hydraulic device to assist in controlling the compaction degree of the sand mold.

[0006] Furthermore, the long mounting slots of the base are distributed at both ends along the length of the base, which facilitates the precise positioning and installation of the device with external casting equipment by bolts; the support blocks include at least two, each symmetrically arranged on both sides of the top surface of the base, to improve the stability of the support for the main frame.

[0007] Furthermore, the main frame has threaded connection holes on its side that match the threaded adjustment component, and the support block has internal threaded holes at the corresponding positions. The threaded adjustment component passes through the threaded connection holes of the main frame and is screwed into the internal threaded holes of the support block. Tightening the threaded adjustment component can adjust the installation position of the main frame on the support block, indirectly assisting in adjusting the sand mold bearing space.

[0008] Furthermore, the intermediate adjustment plate has through holes that match the threaded adjustment components. The threaded adjustment components pass through the through holes of the intermediate adjustment plate and are screwed into the pre-set internal threaded holes of the support block. By screwing the protruding end of the threaded adjustment components, the distance between the intermediate adjustment plate and the main frame can be precisely adjusted. The threaded adjustment components are also equipped with locking nuts. The locking nuts are screwed onto the end of the threaded adjustment components that protrudes from the top surface of the intermediate adjustment plate. Tightening the locking nuts can lock the adjusted distance and prevent loosening during the vibration process.

[0009] Furthermore, the number of hydraulic interface components is at least two, and each hydraulic interface component is symmetrically assembled on the outer side wall of the support block. The external thread of the hydraulic interface component is used to screw into the connector of the external hydraulic pipeline to realize the hydraulic passage between the external hydraulic device and this device, and to ensure the sealing and stability of the hydraulic transmission.

[0010] One or more technical solutions provided in this application embodiment have at least the following technical effects or advantages compared with the prior art: This invention solves the problem of poor compatibility between the device and external equipment by using a base with a long mounting groove, enabling precise positioning and assembly with external casting equipment. The support block with a hydraulic interface assembly position and symmetrically arranged hydraulic interface components standardize the connection structure of the external hydraulic device, improving the convenience and sealing of hydraulic connections. The inclined sand mold bearing part inside the main frame provides a stable positioning space for the sand mold, preventing sand mold displacement during compaction. The threaded adjustment component, along with the threaded engagement structure of the intermediate adjustment plate, main frame, and support block, enables precise adjustment of the sand mold compaction spacing, replacing the traditional coarse adjustment method and improving adjustment efficiency and accuracy. Simultaneously, the connection to the external hydraulic device via the hydraulic interface components stably controls the compaction density of the sand mold, effectively improving the quality of casting production.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] It should be noted that the terms "vertical," "horizontal," "up," "down," "left," "right," and similar expressions used in this article are for illustrative purposes only and do not represent the only possible implementation.

[0016] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0017] like Figure 1 As shown, base 1 serves as the bottom bearing foundation, support blocks 2 are symmetrically fixed to both sides of the top surface of base 1, the main frame 3 is assembled on the top surface of support blocks 2, the intermediate adjusting plate 4 is connected to the top of the main frame 3 via threaded adjusting parts 5, and the hydraulic interface parts 6 are assembled on the outer wall of support blocks 2. The key to implementation lies in the fact that each component forms a complete force-bearing system through threaded connections and positioning. The innovation lies in integrating spacing adjustment, hydraulic connection, and sand mold bearing into one unit, solving the problem of the dispersed structure of existing devices. Specifically, the long mounting groove of base 1 enables rapid positioning with external equipment, and the standardized assembly of support blocks 2 and hydraulic interface parts 6 ensures the sealing of the hydraulic connection. The overall structure improves the integration and stability of the device.

[0018] like Figure 2 As shown, the connection between the intermediate adjusting plate 4 and the main frame 3 is clearly visible. The threaded adjusting component 5 passes through the through hole of the intermediate adjusting plate 4 and the threaded connection hole 32 of the main frame 3 in sequence before being screwed to the support block 2. The key point of implementation is to make precise adjustments by directly observing the distance between the intermediate adjusting plate 4 and the main frame 3. The innovation lies in exposing the core adjustment components for easy operation and maintenance. This structure solves the problem of poor visualization of the adjustment process in existing devices. The external thread fit design of the threaded adjusting component 5 enables the distance adjustment accuracy to reach the millimeter level, improving the adjustment efficiency and accuracy.

[0019] like Figure 3As shown, the inclined sand mold bearing part 31 inside the main frame 3 is prominent. The main frame 3 is fixed to the support block 2 by the threaded adjustment part 5 on the side. The key point of implementation is to achieve positioning by adapting the inclined sand mold bearing part 31 to the shape of the sand mold. The innovation lies in the specially designed bearing structure replacing the open bearing. This structure solves the problem of unstable sand mold positioning in the existing device. The inclined bearing surface can limit the lateral displacement of the sand mold. Combined with the box-shaped structure of the main frame 3, it improves the stability of the sand mold during the vibration compaction process and reduces the dimensional deviation of the casting.

[0020] like Figure 4 As shown, the assembly relationship of the base 1, support block 2, and hydraulic interface component 6 is clear. The support block 2 is fixed to the base 1 with bolts, and the hydraulic interface component 6 is screwed into the hydraulic interface assembly hole of the support block 2. The key points of implementation are the standardized assembly of basic components and the standardized setting of hydraulic interfaces. The innovation lies in integrating the hydraulic interface into the support block 2 instead of temporary welding. This design solves the problem of non-standard hydraulic connection in existing devices. The symmetrical arrangement of the support block 2 ensures balanced force distribution, and the external thread connection of the hydraulic interface component 6 makes it easy to disassemble and assemble external hydraulic pipelines. At the same time, the sealant seal improves the stability of hydraulic transmission.

[0021] like Figure 5 As shown, after the top middle plate is disassembled, the fit between the through hole of the middle adjusting plate 4 and the threaded adjusting component 5 and the locking nut is clear. The key to implementation is locking the adjusted spacing using the locking nut. The innovation lies in the integrated design of threaded adjustment and locking; this structure solves the problem of loosening after spacing adjustment in existing devices. The high-strength bolt material of the threaded adjusting component 5 ensures load-bearing capacity, and the locking nut effectively prevents thread loosening caused by vibration during sand mold compaction, ensuring the consistency of spacing during sand mold compaction and improving the stability of casting quality. In this implementation plan, Based on the above specific implementation structure, this device can be linked with different existing casting equipment to adapt to various production scenarios. The following details the connection, installation and structural usage status under different usage conditions in conjunction with existing technology devices.

[0022] Scenario 1: Suitable scenarios for small-scale sand casting production lines The existing equipment is a standard single-station vibratory compaction table. This device is fixed to the pre-drilled mounting holes on the worktable surface of the vibratory compaction table via a long mounting groove on the base 1 using M16 high-strength bolts. The lateral position of the device can be finely adjusted when the bolts pass through the groove to ensure alignment with the sand mold feeding trajectory of the existing feeding mechanism. Support blocks 2 are symmetrically fixed to both sides of the top surface of the base 1, with the top surface supporting the main frame 3. The hydraulic interface 6 connects to the high-pressure pipeline of the existing small hydraulic pump station, using PT1 / 2 threaded connectors and sealing with PTFE tape. In use, the sand mold is placed on the inclined sand mold bearing part 31 of the main frame 3, with the inclined surface conforming to the sand mold to limit displacement. Tightening the threaded adjusting part 5 (M20 high-strength bolts) adjusts the distance between the intermediate adjusting plate 4 and the top surface of the sand mold to 5-10mm, and then tightening the locking nut secures it. The vibratory compaction table and hydraulic pump station are started, and the hydraulic device transmits pressure to the support blocks 2 via the hydraulic interface 6, coordinating with the vibratory compaction table to compact the sand mold. The long mounting groove on the base 1 prevents vibration displacement of the device, and the symmetrical arrangement of the support blocks 2 ensures uniform pressure transmission.

[0023] Scenario 2: Medium-sized complex sand mold seismic simulation scenario Existing equipment includes an automatic sand feeding mechanism, a hydraulic vibration cylinder, and a temperature control device. The base 1 of this device is slidably connected to the pre-embedded guide rails on the production line floor via a long mounting groove using T-bolts, facilitating adjustment of the front and rear positions according to the sand mold size. The main frame 3 has a detachable wear-resistant liner installed on the inclined sand mold bearing part 31 to accommodate complex sand mold tilt angles. The positioning pin hole on the top surface of the intermediate adjusting plate 4 cooperates with the positioning block of the automatic sand feeding mechanism to achieve rapid sand mold alignment. The number of hydraulic interface components 6 is increased to four, each connected to the inlet and outlet oil lines of the hydraulic vibration cylinder, and the vibration pressure is adjusted via an electromagnetic reversing valve. In use, the automatic sand feeding mechanism delivers the sand mold to below the intermediate adjusting plate 4, and the positioning block's pin hole is pre-positioned. The threaded adjusting component 5 drives the intermediate adjusting plate 4 downwards to press the sand mold. After the locking nut is tightened, the hydraulic vibration cylinder applies periodic pressure through the hydraulic interface components 6. The box-shaped structure of the main frame 3 resists deformation, the inclined sand mold bearing part 31 prevents sand mold misalignment, and the threaded adjusting component 5 precisely controls the spacing of key components.

[0024] Scenario 3: Integration of multi-station linkage casting equipment The existing equipment is a circular casting production line (including sand loading, compaction, mold closing, and pouring stations). This device, as the core component of the compaction station, has a base 1 bolted to the production line conveyor pallet via a long mounting groove. The pallet conveyor moves along the circular track. The hydraulic interface 6 uses an ISO7241-A quick-connect coupling to connect to the central hydraulic system of the production line, enabling rapid hydraulic connection during station switching. The threaded connection hole 32 on the side of the main frame 3 mates with the internal threaded hole of the support block 2. Tightening the threaded adjustment component 5 finely adjusts the front and rear position of the main frame 3, ensuring that the sand mold is aligned with the center of the mold at the next mold closing station. In use, after the sand mold is made at the sand loading station, the pallet conveyor is sent to the compaction station. The central hydraulic system is pressurized through the hydraulic interface 6, and the intermediate adjustment plate 4 maintains a set spacing under the locking of the threaded adjustment component 5. After compaction, the pallet conveyor is sent to the mold closing station. Loosening the threaded adjustment component 5 causes the intermediate adjustment plate 4 to move upward and release the sand mold. The support block 2 is stably connected to the main frame 3 to prevent shaking during sand mold station switching, achieving continuous production linkage.
