Description

Technical Field

[0001] This utility model relates to the field of scraper conveyor technology, and in particular to a casting mold for the sidewalls of a central trough. Background Technology

[0002] A scraper conveyor is a mechanical device that uses a scraper chain to continuously transport bulk materials in a closed trough. It is widely used in industries such as mining, metallurgy, building materials, and chemicals. When in use, the material enters the conveying trough from the feed inlet, and the scraper chain drives the material to slide along the bottom of the trough and be discharged at the discharge outlet. For example, in coal mining, scraper conveyors can be used to transport coal from the mining area to the crushing station or transfer point.

[0003] The central trough is the main part of the conveying trough in a scraper conveyor. Multiple central troughs are connected end to end by bolts or welding to form a continuous material conveying channel. The central trough is generally composed of a bottom plate, a middle plate, and trough sides. Currently, the trough sides are generally made by casting. However, due to the large size of the trough side structure, the traditional casting mold is designed to be correspondingly large, resulting in a heavy mold. During casting, the traditional upper and lower molds need to be adjusted multiple times before they can be closed, which is not only extremely laborious but also affects production efficiency. Utility Model Content

[0004] The purpose of this invention is to address the problem that traditional casting molds in the background art are relatively large in size, resulting in heavy molds. During casting, the upper and lower molds need to be adjusted multiple times before they can be closed, which is not only extremely laborious but also affects production efficiency. This invention provides a casting mold for the side of the central groove.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A casting mold for the sidewalls of a central groove, comprising:

[0007] The lower mold has a casting area in the middle of its upper surface, and multiple limiting posts are provided along the circumference of the casting area. Guide posts are also provided between adjacent limiting posts.

[0008] The upper mold has a casting mold in the middle of its lower surface, and a plurality of limiting grooves are provided along the circumference of the casting mold, with a sliding groove between adjacent limiting grooves;

[0009] The lower mold and the upper mold are configured such that when the lower mold and the upper mold are closed, the guide post is inserted into the slide groove, and the limiting groove cooperates with the limiting post.

[0010] Preferably, the limiting post includes a first circular portion, a second circular portion, and a third rectangular portion connected sequentially from top to bottom, and the first circular portion, the second circular portion, and the third rectangular portion are coaxially arranged.

[0011] The limiting groove includes a first circular groove, a second circular groove, and a third rectangular groove connected sequentially from the inside to the outside, and the first circular groove, the second circular groove, and the third rectangular groove are coaxially arranged.

[0012] The first circular portion and the first circular groove are fitted together, the second circular portion and the second circular groove are fitted together, and the third shaped portion and the third shaped groove are fitted together.

[0013] Preferably, the area of ​​the first circular portion is smaller than that of the second circular portion, and the area of ​​the second circular portion is smaller than that of the third circular portion.

[0014] The area of ​​the first circular groove is smaller than that of the second circular groove, and the area of ​​the second circular groove is smaller than that of the third rectangular groove.

[0015] Preferably, each side of the lower mold has at least one guide post;

[0016] Each of the upper molds has at least one of the slide grooves, and the position of the slide groove on each side corresponds to the position of the guide post on each side.

[0017] Preferably, the guide post and the slide groove are in clearance fit.

[0018] Preferably, the groove extends through the upper mold;

[0019] The length of the guide post is greater than that of the upper mold.

[0020] Preferably, an annular plate is provided on the lower surface edge side of the lower mold;

[0021] The upper surface edge of the upper mold has an annular groove, which is fitted into the annular plate.

[0022] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0023] A limiting post is provided on the upper surface of the lower mold, and a guide post is provided between adjacent limiting posts. A limiting groove is provided on the lower surface of the upper mold, and a sliding groove is provided between adjacent limiting grooves. When closing the lower and upper molds, the lower mold is placed on the ground or platform, and then the upper mold is moved above the lower mold. First, the sliding groove of the upper mold is engaged with the guide post of the lower mold. Once the guide post is inserted into the sliding groove, the upper mold moves along the guide post to the lower mold until the limiting groove of the upper mold engages with the limiting post of the lower mold, thereby realizing the closing of the upper and lower molds. The channel casting mold of this application first achieves the positioning of the upper mold through the sliding engagement of the guide post and the sliding groove, and then limits the upper mold through the engagement of the limiting post and the limiting groove, thus completing the closing of the upper and lower molds. This avoids the need for multiple adjustments between the upper mold and the lower mold during the traditional mold closing process. It is convenient to operate, quick to construct, and greatly improves the production efficiency of the channel. Attached Figure Description

[0043] Example 1

[0044] like Figures 1-5 As shown, this embodiment discloses a casting mold for the sidewalls of a central groove, comprising:

[0045] The lower mold 1 has a casting area 10 in the middle of its upper surface. Multiple limiting posts 3 are provided around the casting area 10, and guide posts 5 are provided between adjacent limiting posts 3.

[0046] The upper mold 2 has a casting mold 20 in the middle of its lower surface. Multiple limiting grooves 4 are provided along the circumference of the casting mold 20, and a sliding groove 6 is provided between adjacent limiting grooves 4.

[0047] The lower mold 1 and the upper mold 2 are configured such that when the lower mold 1 and the upper mold 2 are closed, the guide post 5 is inserted into the slide groove 6, and the limiting groove 4 cooperates with the limiting post 3.

[0048] Limiting posts 3 are provided on the upper surface of the lower mold 1, and guide posts 5 are provided between adjacent limiting posts 3. Limiting grooves 4 are provided on the lower surface of the upper mold 2, and sliding grooves 6 are provided between adjacent limiting grooves 4. When closing the lower mold 1 and the upper mold 2, the lower mold 1 is placed on the ground or platform, and then the upper mold 2 is moved above the lower mold 1. First, the sliding groove 6 of the upper mold 2 engages with the guide posts 5 of the lower mold 1, so that the guide posts 5 are inserted into the sliding grooves 6. The upper mold 2 moves along the guide posts 5 to the lower mold 1 until... The limiting groove 4 of the upper mold 2 cooperates with the limiting post 3 of the lower mold 1 to realize the mold closing of the upper mold 2 and the lower mold 1. The channel casting mold of this application first realizes the positioning of the upper mold 2 through the sliding cooperation of the guide post 5 and the slide 6, and then limits the upper mold 2 through the cooperation of the limiting post 3 and the limiting groove 4 to complete the mold closing of the upper mold 2 and the lower mold 1. This avoids the need for multiple adjustments between the upper mold 2 and the lower mold 1 during the mold closing process of the traditional upper mold 2. It is convenient to operate and quick to construct, which greatly improves the production efficiency of the channel.

[0049] A preferred method, such as Figure 6As shown, the limiting post 3 includes a first circular portion 31, a second circular portion 32 and a third rectangular portion 33 connected sequentially from top to bottom, and the first circular portion 31, the second circular portion 32 and the third rectangular portion 33 are coaxially arranged.

[0050] The limiting groove 4 includes a first circular groove 41, a second circular groove 42 and a third rectangular groove 43 connected sequentially from the inside to the outside. The first circular groove 41, the second circular groove 42 and the third rectangular groove 43 are coaxially arranged.

[0051] The first circular portion 31 is fitted into the first circular groove 41, the second circular portion 32 is fitted into the second circular groove 42, and the third rectangular portion 33 is fitted into the third rectangular groove 43.

[0052] The limiting post 3 includes a three-level limiting part, and the limiting groove 4 includes a three-level limiting groove. Through the above arrangement, the limiting post 3 and the limiting groove 4 fit more tightly.

[0053] Furthermore, the limiting post 3 includes a first circular portion 31, a second circular portion 32 and a third rectangular portion 33 connected sequentially from top to bottom, and the limiting groove 4 includes a first circular groove 41, a second circular groove 42 and a third rectangular groove 43 connected sequentially from inside to outside.

[0054] The upper part of the limiting post 3 is a two-stage circular part, and the inside of the limiting groove 4 is a two-stage circular groove. The above configuration can facilitate the quick engagement of the limiting post 3 and the limiting groove 4.

[0055] The lower part of the limiting post 3 is rectangular, and the outer part of the limiting groove 4 is rectangular. Through the cooperation of the rectangular part and the rectangular groove, the rectangular part can limit the four sides of the rectangular groove, so that after the upper mold 2 is fitted on the limiting post 3, it restricts the upper mold 2 in all four directions (front, back, left, and right) to ensure that the upper mold 2 is installed stably.

[0056] Specifically, the area of ​​the first circular portion 31 is smaller than that of the second circular portion 32, and the area of ​​the second circular portion 32 is smaller than that of the third rectangular portion 33.

[0057] The area of ​​the first circular groove 41 is smaller than that of the second circular groove 42, and the area of ​​the second circular groove 42 is smaller than that of the third rectangular groove 43.

[0058] A preferred method, such as Figure 2 As shown, each side of the lower mold 1 has at least one guide post 5;

[0059] like Figure 4 As shown, each side of the upper mold 2 has at least one groove 6, and the position of each groove 6 corresponds to the position of each guide post 5.

[0060] Preferably, the guide post 5 and the slide groove 6 are in clearance fit.

[0061] Preferably, the groove 6 penetrates through the upper mold 2;

[0062] The length of the guide post 5 is greater than the thickness of the upper mold 2.

[0063] With the above settings, it is ensured that when the upper mold 2 and the lower mold 1 are closed, the guide post 5 can penetrate the upper mold 2 after being inserted into the slide groove 6, so as to ensure that the upper mold 2 can move stably downward along the length of the guide post 5.

[0064] A preferred method, such as Figure 1 , Figure 2 As shown, an annular plate 11 is provided on the lower surface edge side of the lower mold 1;

[0065] like Figure 3 , Figure 4 As shown, the upper surface edge of the upper mold 2 has an annular groove 21, which is fitted into the annular plate 11.

[0066] By setting the annular plate 11 and the annular groove 21 to fit together, a multi-level positioning method is used for the upper mold 2 and the lower mold 1, which further increases the stability after mold closing.

[0067] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
