Obviously, the described embodiments are only a part of the embodiments of this utility model, rather than all the embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this utility model.

[0027] As described in the background art, in the processing of mining machinery enclosures, casting technology has gradually emerged as an important alternative to traditional processing methods. However, during the casting process, especially in the ejection stage after the finished product cools and forms, a series of technical problems are often encountered. Traditional casting molds are not convenient to remove after the product cools and forms.

[0028] To solve this technical problem, the present utility model provides a casting mold for processing mining machinery enclosures.

[0029] Specifically, please refer to Figure 1 - Figure 2 , the casting mold for processing mining machinery enclosures specifically includes:

[0030] A lower mold 1 and an upper mold 2. An installation plate 3 is installed at the top of the upper mold 2, and a support member is installed at the bottom of the lower mold 1. A connecting plate 601 is slidably connected inside the support member. A plurality of ejecting and loosening rods 604 are fixedly connected to the top of the connecting plate 601. The top ends of the ejecting and loosening rods 604 pass through the support member and the lower mold 1, and a buffer pad 602 is provided at the bottom of the connecting plate 601. The connecting plate 601 and the ejecting and loosening rods 604 move under the drive of an external force to realize the ejection of the product.

[0031] For the casting mold for processing mining machinery enclosures provided by the present utility model, in this application, through the arranged connecting plate 601 and ejecting and loosening rods 604, the connecting plate 601 and the ejecting and loosening rods 604 can move upward under the drive of an external force, so as to push the product cooled and formed in the lower mold 1, causing a relative displacement between the product and the lower mold 1, thereby loosening the product and facilitating subsequent manual or mechanical removal.

[0032] To enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0033] It should be noted that, without conflict, the embodiments in the present utility model and the features and technical solutions in the embodiments can be combined with each other.

[0034] It should be noted that similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0035] Example 1, please refer to Figure 1 - Figure 2, A casting mold for processing the protective enclosure of mining machinery, including a lower mold 1 and an upper mold 2. An installation plate 3 is installed at the top of the upper mold 2, and a support member is installed at the bottom of the lower mold 1. A connecting plate 601 is slidably connected inside the support member. A plurality of ejecting rods 604 are fixedly connected to the top of the connecting plate 601. The top ends of the ejecting rods 604 pass through the support member and the lower mold 1, and a buffer pad 602 is arranged at the bottom of the connecting plate 601. The connecting plate 601 and the ejecting rods 604 move under the drive of an external force to realize the top of the product. By providing the connecting plate 601 and the ejecting rods 604, the connecting plate 601 and the ejecting rods 604 can move upward under the drive of an external force, so as to be able to push the product cooled and formed in the lower mold 1, causing a relative displacement between the product and the lower mold 1, thereby loosening the product and facilitating the subsequent manual or mechanical removal. The buffer pad 602 is made of elastic rubber, so that the connecting plate 601 can be buffered by the buffer pad 602 when it descends.

[0036] Further, as Figure 1 - Figure 2 shown, the support member includes a base 4 installed at the bottom of the lower mold 1. Both sides of the bottom of the base 4 are fixedly connected with support plates 401. A bottom plate 402 is fixedly connected between the bottoms of the two support plates 401. The cooperation of the bottom plate 402, the support plates 401 and the base 4 can support the lower mold 1.

[0037] Further, as Figure 2 shown, a plurality of limiting rods 603 are fixedly connected between the support plate 401 and the bottom plate 402. The outer surface of the limiting rod 603 passes through the connecting plate 601 and the buffer pad 602. The limiting rod 603 can limit the connecting plate 601, making the lifting of the connecting plate 601 more stable.

[0038] Embodiment 2 further optimizes the casting mold for processing the protective enclosure of mining machinery provided in Embodiment 1. Specifically, as Figure 1 and Figure 2 shown, a plurality of positioning columns 5 are fixedly connected to the bottom of the installation plate 3. A plurality of positioning grooves 501 are opened at the top of the base 4. The inner wall of the positioning groove 501 is inserted with the bottom end of the positioning column 5. The cooperation of the positioning column 5 and the positioning groove 501 can limit the lower mold 1 and the upper mold 2 during mold closing, improving the accuracy after the lower mold 1 and the upper mold 2 are closed.

[0039] Further, as Figure 2 shown, sliding grooves 7 are opened on both support plates 401. Slide plates 701 are slidably connected in the two sliding grooves 7. The slide plates 701 are fixedly connected to the connecting plate 601. A transmission plate 702 is fixedly connected to the top of the slide plate 701.

[0040] Embodiment 3 further optimizes the casting mold for processing the protective enclosure of mining machinery provided in Embodiment 1 or 2. Specifically, asFigure 1 and Figure 3 As shown in Figure 3 , drive mechanisms 8 are provided on both sides of the mounting plate 3 and the base 4. The drive mechanism 8 includes a connecting column 801 fixedly installed at the bottom of the mounting plate 3. A groove is formed at the bottom of the connecting column 801. A connecting shaft 803 is installed in the groove, and a rocker 804 is sleeved on the outer surface of the connecting shaft 803. The rocker 804 can rotate around the connecting shaft 803.

[0041] Furthermore, as Figure 4 shown in Figure 4 , a circular groove 810 centered on the connecting shaft 803 is formed on the side surface of the rocker 804. A coil spring 811 is arranged in the circular groove 810. The two ends of the coil spring 811 are fixedly connected to the circular groove 810 and the connecting shaft 803 respectively. The acting force of the coil spring 811 can keep the rocker 804 horizontal in the natural state.

[0042] Furthermore, as Figure 1 and Figure 3 shown in Figure 1 and Figure 3 , a first support shaft 805 is inserted through the connecting column 801. One end of the first support shaft 805 is fixedly connected to a lifting plate 806. Guide wheels 808 are fixedly connected to both the top and bottom of the lifting plate 806. A wedge-shaped plate 802 located on one side of the connecting column 801 is fixedly installed on the side surface of the base 4. The guide wheel 808 at the bottom of the lifting plate 806 contacts the top of the rocker 804. Through the mutual cooperation of the first support shaft 805, the lifting plate 806 and the guide wheels 808, the rocker 804 can be limited, so that the connecting column 801 can drive the transmission plate 702 to rise through the rocker 804. Further, the connecting plate 601 can be driven to rise through the transmission plate 702 and the sliding plate 701. During the rising process of the connecting column 801, the guide wheel 808 at the top of the lifting plate 806 moves away from the connecting column 801 under the limitation of the wedge-shaped plate 802. When the guide wheel 808 at the bottom of the lifting plate 806 is separated from the rocker 804, the rocker 804 rotates and is separated from the transmission plate 702. At this time, the connecting plate 601 moves downward and resets under the action of gravity, so that the ejector rod 604 ejects and loosens the product during the rising process of the upper mold 2.

[0043] Furthermore, as Figure 3 shown in Figure 3 , a spring 807 is sleeved on the outer surface of the first support shaft 805. The two ends of the spring 807 are fixedly connected to the connecting column 801 and the first support shaft 805 respectively. The acting force of the spring 807 can pull the lifting plate 806 through the first support shaft 805.

[0044] Furthermore, as Figure 3As shown in the figure, a second support shaft 809 is also inserted and connected to the connecting column 801. One end of the second support shaft 809 is fixedly connected to the lifting plate 806. Linear bearings are provided between the outer surfaces of the second support shaft 809 and the first support shaft 805 and the connecting column 801. The setting of the second support shaft 809 can prevent the lifting plate 806 from rotating. The second support shaft 809 and the first support shaft 805 are not in the same plane as the wedge plate 802, so that the wedge plate 802 will not contact the second support shaft 809 and the first support shaft 805.

[0045] The use process of the casting mold for processing the mine machinery enclosure provided by the present utility model is as follows:

[0046] When the upper mold 2 rises, the first support shaft 805, the lifting plate 806 and the guide wheel 808 cooperate with each other to limit the rocker 804, so that the connecting column 801 can drive the transmission plate 702 to rise through the rocker 804. Then, the transmission plate 702 and the slide plate 701 drive the connecting plate 601 to rise, and the connecting plate 601 drives the top loosening rod 604 to rise to push the product. During the rising process of the connecting column 801, the guide wheel 808 at the top of the lifting plate 806 moves away from the connecting column 801 under the limit of the wedge plate 802. When the guide wheel 808 at the bottom of the lifting plate 806 separates from the rocker 804, the rocker 804 rotates and separates from the transmission plate 702. At this time, the connecting plate 601 moves downward and resets under the action of gravity;

[0047] When the upper mold 2 descends, the end of the rocker 804 close to the transmission plate 702 first contacts the top of the transmission plate 702, and then the rocker 804 rotates to the vertical under the action of the transmission plate 702. The connecting column 801 continues to drive the rocker 804 to move downward. When the rocker 804 separates from the transmission plate 702, the rocker 804 rotates to the horizontal under the action of the coil spring 811.
