Description

Technical Field

[0001] This invention relates to a small core mold positioning and filling device and a solid propellant loading device for engines. Background Technology

[0002] Currently, the assembly methods for small experimental components such as core molds and shells for solid rocket engines are outdated, still primarily relying on manual, face-to-face work. This process is prone to safety hazards related to equipment, personnel, and products due to human error. The current method involves manually embedding the core mold into the flared end of the shell through methods such as bumping and pressing. These bumping and pressing processes are inherently risky and lead to low production efficiency and susceptibility to human error in product quality. Furthermore, this outdated method increases the workload for workers, resulting in time-consuming and labor-intensive processes. Optimizing production methods to replace manual, face-to-face work is an inevitable trend in the future of the fire-fighting industry. Such optimization can improve production efficiency, enhance the inherent safety of frontline workers, and ultimately liberate productivity. Summary of the Invention

[0003] The technical problem to be solved by this invention is to overcome the shortcomings of the prior art, aiming to improve the production efficiency of manual assembly and reduce the burden of labor, and to solve the impact of human error in the manual assembly process.

[0004] The objective of this invention is achieved through the following technical solutions:

[0005] A small core mold positioning and filling device includes an upper hydraulic core ejector, a device body, an upper core mold retaining ring, an upper core mold, a support rod, a housing positioning retaining ring, a lower hydraulic core ejector and its control system, a device operation control panel, a device manual / automatic mode switching knob, and device casters.

[0006] The upper part of the small core mold positioning and filling equipment includes a main body, an upper hydraulic core-lifting device, an upper core mold, and an upper core mold retaining ring. After the equipment starts, the upper core mold moves from top to bottom under the drive of the upper hydraulic core-lifting device. The upper core mold and the upper core mold retaining ring engage the core mold housing on the housing positioning retaining ring, cooperating with the lower hydraulic core-lifting device to complete the assembly operation between the housing and the core mold. The middle part of the small core mold positioning and filling equipment includes a housing positioning retaining ring, support rods, an equipment operation panel, and a manual / automatic mode switching knob, used for guiding and positioning during the assembly process and controlling the equipment's lifting and lowering operations. The lower part of the small core mold positioning and filling equipment consists of a lower hydraulic core-lifting device and its control system, and equipment casters, used to control the equipment's lifting and lowering operations, the operation of the lower hydraulic core-lifting device, and the equipment's translation and rotation.

[0007] Optionally, the upper hydraulic core-ejector device is a device that works in conjunction with the lower hydraulic core-ejector device, support rod, and housing positioning retaining ring, and integrates with the equipment control system. It replaces manual assembly of the housing and core mold by operators. Its operating principle is as follows: the core mold is placed on the lower hydraulic core-ejector device, whose upper surface has grooves for auxiliary positioning and guidance; then the housing is placed in the groove of the housing positioning retaining ring, achieving positioning and guidance functions through the groove; then the upper hydraulic core-ejector device, in conjunction with the upper core mold retaining ring and the upper core mold, moves downwards along the guide rod. The annular upper core mold retaining ring is installed on the outside of the upper core-ejector device mold, and the upper core mold and upper core mold retaining ring can be replaced with tooling components according to the model and production type, with their internal shape closely fitting the core mold's outer shape; simultaneously, the lower hydraulic core-ejector device carries the core mold upwards until the upper core mold and upper core mold retaining ring press against the housing. With the upper and lower hydraulic core-ejector devices acting simultaneously, the directional automatic assembly of the core mold and housing is completed through hydraulic operation.

[0008] Optionally, the upper core mold has the function of moving up and down with the hydraulic core device. The internal groove of the upper core mold can fit tightly with the core mold, so as to position, guide and center the core mold during the downward movement of the upper hydraulic core device, the upper core device mold and its retaining ring. This avoids assembly errors caused by positional deviation of the core mold shell during assembly. Furthermore, the groove guide ensures that the assembly operation can be completed after the upper and lower core strokes reach the designed stroke. The upper core mold and the shell positioning retaining ring have a guiding function, which can accurately complete the guiding and positioning assembly operation.

[0009] Optionally, the equipment operation panel has functions such as controlling the top core assembly speed, stroke alarm, stroke setting and lifting control, and equipment emergency stop.

[0010] Optionally, the lower hydraulic jacking device and its control system have memory learning function, hydraulic jacking upper and lower synchronous control function, stroke detection function, oil pressure alarm function, jacking force overload alarm function, and remote control function, and provide both manual and automatic operation modes.

[0011] Optionally, the internal groove of the housing positioning retaining ring is designed according to the actual size of the housing. This addresses the issue of human error during assembly causing deviations in the housing center distance, resulting in the core mold failing to reach the designated position during assembly and leading to subsequent quality problems. This patent addresses these shortcomings by designing a tooling with housing guiding and positioning functions. It provides guiding support to the housing during the operation of the upper and lower hydraulic core-lifting devices, preventing housing tilting and assembly failure.

[0012] Optionally, the lower hydraulic core device has the function of lifting up and down, which can automatically dock and assemble the core mold with the shell.

[0013] Optionally, the applicable equipment caster wheel has the ability to operate in multiple modes, and the caster wheel has a locking function.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] (1) This invention solves the problem of human error in manual assembly and avoids situations such as drug leakage or drug shape deviation caused by improper assembly of the shell and core mold.

[0016] (2) The automatic assembly operation of the present invention is convenient. It can be completed in manual mode or fully automatic mode, which reduces the labor intensity of operators and improves the efficiency of casting operation.

[0017] (3) The core mold positioning and filling equipment can perform high-risk operations such as remote manual demolding by changing the upper core mold. Attached Figure Description

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0023] A small core mold positioning and filling device includes: a main body 2, an upper hydraulic core-ejecting device 1, an upper core mold 4, an upper core mold retaining ring 3, a support rod 6, a housing positioning retaining ring 7, a core lowering button 8, an emergency stop button 9, a core raising button 10, a machine housing door lock 11, a lower hydraulic core-ejecting device and equipment control system 13, an equipment operation control panel, a manual / automatic mode switching knob 14, and equipment casters 15, etc. Figure 1 As shown. The small core mold positioning and loading equipment places the core mold 12 into the housing positioning retaining ring 7 and then into the groove of the lower hydraulic core ejector device, completing the positioning and guidance of the core mold to facilitate the core mold loading operation. Subsequently, the housing 5 is placed in the groove within the housing positioning retaining ring 7 to complete the positioning and loading of the housing, avoiding misoperation caused by positional deviation during the assembly process. Then, the upper and lower hydraulic core ejector devices 1 and 13 of the automatic loading equipment are started. The equipment control system automatically controls the core ejector stroke. The upper and lower hydraulic core ejector devices have a force feedback module to ensure that the loading is within the process requirements. Under the action of the driving force, the upper hydraulic core ejector device 1 drives the upper core mold 4 and the upper core mold retaining ring 3 to descend, while the lower hydraulic core ejector device 13 drives the core mold 12 to rise synchronously. When the two are close, the upper core mold guides the core mold housing to fit through the internal groove, and at the same time, the upper core retaining ring 3 completes the auxiliary guiding and positioning operation to ensure that the core mold housing is assembled in place.

[0024] The upper core mold described herein has an internal groove that allows for the replacement of upper core molds 4 of different shapes and sizes via a quick-change platform, according to the model and task, achieving versatility, practicality, and high operability. Furthermore, it can cooperate with the upper and lower hydraulic core devices 1 and 13 and the upper core positioning retaining ring 3 to form a stroke guiding and positioning function. Through intelligent learning of the system, it can quickly complete automatic assembly operations, achieving rapid and accurate positioning during the assembly process and resolving potential hazards such as leakage and asymmetry of the drug formulation caused by human error.

[0025] The design of a quick-positioning groove on the lower hydraulic core device platform enables visual and rapid positioning based on the groove's dimensions, thereby improving the efficiency and accuracy of casting and assembly, and effectively preventing phenomena such as assembly tilting or incomplete assembly.

[0026] Furthermore, such as Figure 1-3 As shown, as a specific embodiment of a positioning and filling device for small core molds provided by the present invention, the main body and structural components of the positioning device are all welded from steel plates or lightweight alloys.
