Description

Technical Field

[0001] This utility model relates to the field of wax pressing equipment technology, and in particular to a novel medium-temperature wax pressing machine. Background Technology

[0002] Wax press is a key piece of equipment in precision casting processes used to produce investment molds (wax molds). It injects molten wax into a metal mold under high pressure, and after cooling, a wax mold of the desired shape is obtained.

[0003] In existing technologies, the nozzle of a wax injection machine is usually fixed relative to the mold clamping mechanism. This design reveals significant limitations when dealing with molds of different specifications. When it is necessary to change to a mold with different height, thickness, or wax injection port position, operators must spend a lot of time on tedious mechanical adjustments or changing special tooling fixtures. This results in low mold change efficiency, making it difficult to meet the current requirements of flexible production with small batches and multiple varieties, and lacking versatility.

[0004] Furthermore, traditional wax injection machines typically complete all processes at a single workstation, with mold closing, wax injection, cooling, and demolding all occurring directly below the nozzle. This integrated design forces the demolding mechanism to be crammed into a small space alongside the complex mold closing and wax injection systems. This not only increases the structural complexity and manufacturing costs of the core area but also limits production efficiency. The high temporal and spatial coupling of these processes creates a bottleneck, hindering more efficient cyclical production.

[0005] Therefore, this utility model proposes a novel medium-temperature wax pressing machine to overcome the shortcomings of the existing technology. Utility Model Content

[0010] Preferably, the adjustment mechanism includes a mounting plate fixed to the machine body, a first cylinder, a fixed block, and a second cylinder; the output end of the first cylinder is connected to the fixed block to drive the fixed block to move up and down; the output end of the second cylinder passes through the fixed block and is connected to the nozzle to drive the nozzle to move back and forth.

[0011] Preferably, the sliding mechanism includes a third cylinder, a connecting plate, a slide rail, a slider mounted on the lower closing template, and a slide groove opened on the machine body; the third cylinder drives the connecting plate to slide in the slide groove, thereby driving the slider to move along the slide rail.

[0012] Preferably, the demolding mechanism includes a fourth cylinder, a second guide rod, a lifting plate, and a lifting rod; the fourth cylinder drives the lifting plate to rise and fall under the guidance of the second guide rod, so that the lifting rod passes through the first through hole provided on the demolding station of the machine body and the second through hole on the lower mold plate to eject the wax mold.

[0013] Preferably, the wax supply mechanism includes a wax melting box, a paste-making barrel, a wax pressing box, a wax pressing cylinder, a wax conveying box, and a wax conveying cylinder; the wax conveying cylinder is used to pump the wax liquid in the paste-making barrel through the wax conveying box to the wax pressing cylinder located in the wax pressing box.

[0014] Preferably, the wax melting box is equipped with a temperature control system; the ointment making tank is equipped with a drive motor, a rotating shaft and a stirring arm, and the drive motor drives the rotating shaft to rotate the stirring arm.

[0015] Preferably, the mold closing mechanism includes a hydraulic cylinder driven by a hydraulic mechanism and a first guide rod; the hydraulic cylinder is used to drive the upper mold closing plate in the mold closing mechanism to move under the guidance of the first guide rod.

[0016] Preferably, the novel medium-temperature wax press also includes an electrical control mechanism, a pneumatic mechanism that provides power to the first cylinder, the second cylinder, the third cylinder and the fourth cylinder, and a protective cover and cabinet door covering the outside of the machine body; the protective cover is interlocked with the electrical control mechanism.

[0017] This utility model has the following beneficial effects: 1. In this utility model, by setting an adjustment mechanism that can drive the nozzle to move vertically and horizontally in two dimensions, the problem of fixed nozzle position, difficulty in adapting to different mold specifications, and poor versatility of the existing wax press machine is solved. The technical effect of being able to flexibly and quickly adjust the nozzle position to adapt to different molds is achieved, thereby significantly improving the equipment versatility and mold changing efficiency.

[0018] 2. In this utility model, by setting a sliding mechanism that can move the lower mold plate from the wax injection station to an independent demolding station, the problem of wax injection and demolding processes being carried out in the same position in the prior art, resulting in complex structure of the core area and interference between processes, is solved.

The paste-making tank 502 is also equipped with a drive motor 503, a rotating shaft 504, and a stirring arm 505. The output shaft of the drive motor 503 is connected to the rotating shaft 504. The rotating shaft 504 drives the stirring arm 505 to rotate and stir the wax liquid. The wax conveying tank 12 and the nozzle 3 are both connected to the wax pressing cylinder 507 through pipes. The wax conveying cylinder 14 is located at the upper end of the wax conveying tank 12 and is used to pump the wax liquid in the paste-making tank 502 to the wax pressing cylinder 507 located inside the wax pressing tank 506.

[0029] As another preferred embodiment, to provide a strong and stable mold clamping force, please refer to... Figure 3 and Figure 4 The mold closing mechanism 2 of this novel medium-temperature wax press includes a hydraulic cylinder 201 driven by a hydraulic mechanism 9 and a first guide rod 202.

The output end of the hydraulic cylinder 201 is fixedly connected to the top surface of the upper mold plate 203. The first guide rod 202 is vertically fixed parallel to the upper mold plate 203. The machine body 1 is provided with a guide hole that slides with the first guide rod 202 to ensure that the upper mold plate 203 can move up and down smoothly and accurately under the drive of the hydraulic cylinder 201.

[0030] As another preferred implementation method, in order to achieve automated control and safety protection of the equipment, please refer to... Figure 1 , Figure 2 and Figure 8 The new medium-temperature wax press also includes an electrical control mechanism 8, a pneumatic mechanism 10, a protective cover 11, and a cabinet door 13. The electrical control mechanism 8 is integrated into the electrical control cabinet of the machine body 1 and is the control core of the whole machine.

[0031] Working principle: Before the equipment starts, the temperature control system in the wax supply mechanism 5 heats and melts the solid wax in the wax melting tank 501. The wax flows into the paste making tank 502. The drive motor 503 drives the stirring arm 505 to stir the wax. Then, the wax conveying cylinder 14 repeatedly pumps and presses, conveying the uniform wax through the wax conveying tank 12 to the wax pressing cylinder 507 for later use. When it is necessary to inject wax into a specific mold, the operator controls the pneumatic mechanism 10 through the electrical control mechanism 8, driving the first cylinder 402 and the second cylinder 404 of the adjusting mechanism 4 to move, so that the nozzle 3 moves precisely and aligns with the wax injection port of the mold. After positioning, the hydraulic mechanism 9 drives the hydraulic cylinder 201 of the mold closing mechanism 2 to move, so that the upper mold closing plate 203 moves smoothly down under the guidance of the first guide rod 202, and completes the mold closing and locking with the lower mold closing plate 204. Then, the wax pressing cylinder 507 injects the medium-temperature wax through the nozzle 3. After wax injection into the mold cavity, the pneumatic mechanism 10 drives the third cylinder 601 of the sliding mechanism 6 to move, causing the lower mold plate 204 and its slider 604 to move along the slide rail 603 from the wax injection station to the demolding station. Upon reaching the demolding station, the pneumatic mechanism 10 drives the fourth cylinder 701 of the demolding mechanism 7 to move, causing the lifting plate 703 and the lifting rod 704 to rise. The lifting rod 704 passes through the first through hole 705 on the demolding station of the machine body 1 and the second through hole 706 on the lower mold plate 204, ejecting the formed wax mold and completing the demolding. Throughout the process, the protective cover 11 is always interlocked with the electrical control mechanism 8 to ensure the safety of operation. Through the coordinated action of the adjusting mechanism 4 and the sliding mechanism 6, this utility model solves the problems of poor versatility caused by the fixed nozzle position of the existing wax press machine, as well as the complex structure and low efficiency caused by the concentration of processes.
