Description

Technical Field

[0001] The utility model relates to the technical field of track casting moulds, in particular to a press-fit type track casting mould. Background Art

[0002] Track casting mold is a special mold used to manufacture tracks. Track casting mold is mainly used in rail transportation fields such as railways, subways, light rails, and places where tracks need to be laid in some industrial fields. With the continuous development of rail transportation, the demand for the quality and quantity of tracks is also increasing. The application prospects of track casting molds are very broad.

[0003] During the production process of the track, the staff puts the relevant casting materials into the molding cavity of the mold, and then extrude the track into shape inside the mold cavity through the extrusion effect of the punch. The vertical cross-section of the track is usually an H-shaped structure. After the track is produced, the interior of the H-shaped track usually contains an auxiliary extrusion molding structure that is not convenient to remove from the inside of the track. It is usually necessary to disassemble the mold before taking out the molded track, which is cumbersome and will increase the workload of the staff, affecting the production efficiency of the track.

[0004] The existing patent (announcement number: CN219944577U) is a press-fit track casting mold. The upper mold seat drives the punch to slide upward and detach from the inside of the cavity. After the upper mold seat slides upward and detaches from the top of the pressure plate, the spring pushes the disc to slide, and the sliding of the disc drives the sliding rod to slide. The sliding of the sliding rod drives the slider to slide into the inside of the slide groove and detach from the inner wall of the H-shaped track. At this time, the staff can use the electromagnet to directly suck the track out of the inside of the cavity, and the formed track can be taken out without disassembling the mold.

[0005] In view of the above problems, the existing patent provides a solution. After the applicant consulted the existing patent (Announcement No.: CN219944577U), the following problems were found: after the upper die seat and the lower die seat in the existing technical solution cast the H-type rail, the casting residues and oxides attached to the inner wall of the lower die seat are not convenient to clean and remove, and these impurities may be mixed into the new casting and affect the quality of the casting.

[0006] Therefore, a press-fit rail casting mold is proposed. Utility Model Content

[0007] The purpose of the utility model is to provide a press-fit rail casting mold, which can solve the problem that after the upper mold base and the lower mold base in the prior art cast the H-shaped rail, the casting residues and oxides attached to the inner wall of the lower mold base are inconvenient to clean and remove, and these impurities may be mixed into the new casting and affect the quality of the casting.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a press-fit rail casting mold, comprising an upper mold base body, a lower mold base body and a disc body, a cleaning mechanism is arranged on the left side of the lower mold base body, a rotating mechanism is arranged on the top of the cleaning mechanism, and a fixing plate is fixedly connected to the bottom of the left side of the lower mold base body;

[0009] The cleaning mechanism includes a fixed bar, a scraping frame, two suction pipes and a suction hood. The top of the scraping frame is fixedly connected to the bottom of the fixed bar, the suction hood is fixedly connected to the inner wall of the scraping frame, the bottom of the suction pipe is fixedly connected to the top of the suction hood, and the top of the suction pipe passes through the fixed bar and extends to the top of the fixed bar.

[0012] Preferably, a limit button is provided on the top of the rotating plate, and the bottom of the limit button passes through the rotating plate and is connected to the internal thread of the rotating block.

[0013] Preferably, a chamfer is provided on the surface of the scraper frame, and the surface of the scraper frame is in active contact with the inner wall of the lower die base body.

[0014] Preferably, a fixing column is fixedly connected to the top of the fixing bar, a sliding block is fixedly sleeved on the surface of the fixing column, and the sliding block is slidably connected to the inside of the sliding groove.

[0015] Preferably, the top of the fixed plate is fixedly connected to an electric telescopic rod, and the bottom of the rotating block is fixedly connected to the top of the telescopic end of the electric telescopic rod.

[0016] Preferably, a handle is fixedly connected to the top of the fixing column.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] 1. The present application moves the scraper frame until the surface of the scraper frame contacts the inner wall of the lower die base body, then connects the external vacuum cleaner to the suction pipe, and then moves the handle by hand. At this time, the scraping action of the scraper frame is used to remove the residue on the inner wall. At the same time, the suction cover and the suction pipe cooperate to timely suck away and clean the scraped residue. The chamfers on the scraper frame surface help to better fit the inner wall of the lower die base body, thereby improving the cleaning effect. At this time, the residue remaining on the surface of the upper die base body can be conveniently brushed off with an external wire brush, thereby avoiding the problem that after the upper die base and the lower die base in the prior art cast the H-shaped track, the casting residue and oxide attached to the inner wall of the lower die base are inconvenient to clean and remove, and these impurities may be mixed into the new casting and affect the quality of the casting.

[0019] 2. In the present application, the scraper frame can be moved conveniently by sliding the slider inside the slide groove, and the rotating block can be rotated and connected inside the rotating hole to facilitate the rotation of the rotating plate. By rotating the rotating plate to the top of the lower die base body, and then rotating the limit button to connect with the internal thread of the rotating block, the rotating plate and the scraper frame can be limited to the top of the lower die base body.

The chamfers on the surface of the scraper frame 502 help to better fit the inner wall of the lower die base body 2 and improve the cleaning effect. At this time, the residue remaining on the surface of the upper die base body 1 can be easily brushed off using an external wire brush, avoiding the problem that after the upper die base and the lower die base in the prior art cast the H-type rail, the casting residue and oxides attached to the inner wall of the lower die base are inconvenient to clean and remove, and these impurities may be mixed into the new casting and affect the quality of the casting.

[0031] Specifically, Figure 3 As shown, the rotating mechanism 6 includes a slide groove 601 , a rotating plate 602 and a rotating block 603 , and the slide groove 601 is opened inside the rotating plate 602 .

[0032] Specifically, Figure 4 As shown, a rotating hole 8 is opened inside the rotating plate 602 , and the rotating block 603 is rotatably connected inside the rotating hole 8 .

[0033] Specifically, Figure 1 , Figure 2 and Figure 4 As shown, a limit button 12 is disposed on the top of the rotating plate 602 , and the bottom of the limit button 12 passes through the rotating plate 602 and is connected with the internal thread of the rotating block 603 .

[0034] In this embodiment: the slider 9 slides inside the slide groove 601 to facilitate the movement of the scraper frame 502, and the rotating block 603 is rotated and connected inside the rotating hole 8 to facilitate the rotation of the rotating plate 602. By rotating the rotating plate 602 to the top of the lower mold base body 2, and then rotating the limit button 12 to connect with the internal thread of the rotating block 603, the rotating plate 602 and the scraper frame 502 can be limited at the top of the lower mold base body 2.

[0035] Specifically, Figure 3 As shown, the surface of the scraper frame 502 is chamfered, and the surface of the scraper frame 502 is in active contact with the inner wall of the lower mold base body 2.
