Description

TECHNICAL FIELD

[0001] The utility model relates to a die casting device field, specifically for a die casting device for casting processing. BACKGROUND

[0002] Casting processing usually includes raw material preparation, smelting, pouring, cooling and solidification, cleaning and subsequent processing and the like steps. These steps jointly determine the quality, performance and cost of the casting, and the casting processing is widely applied to the fields of automobile, machinery, aerospace, building and the like, and is an indispensable part in the manufacturing industry.

[0003] In the casting processing process, the casting mold is a mold used for shaping the casting in the casting forming process, and the design directly determines the shape, size and precision of the casting. The design of the mold needs to consider the use requirements of the casting, the production process and the characteristics of the material to ensure that the casting can meet the expected performance and quality. In order to prevent the casting mold after casting from being stuck in the mold after die casting is completed, a plurality of ejector pins are usually slidingly installed at the bottom of the mold. The ejector pins are extruded, and then the parts after casting are pushed out of the mold.

[0004] However, the traditional ejector pin is installed by passing the ejector pin through the through hole in the ejector pin fixing plate, and the ejector pin is limited in the through hole of the first ejector pin fixing plate by using another ejector pin fixing plate, so as to ensure the normal work of the ejector pin. However, the traditional ejector pin fixing plate is fixed by using screws during installation. This way is not convenient during installation, and reduces the practicability of the device. UTILITY MODEL CONTENTS

[0005] Therefore, the utility model aims at providing a die casting device for casting processing to solve the technical problems mentioned in the background.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a die casting device for casting processing, comprising a mold base and an ejector pin fixing plate, the outer wall of the ejector pin fixing plate is fixedly installed with a limiting block, a double-direction screw rod is rotatably installed in the mold base, a sliding rod is fixedly installed in the mold base, a transmission groove is formed in the end of the double-direction screw rod, a sliding block is threadedly installed on the outer wall of the double-direction screw rod, a square block is fixedly installed on the outer wall of the sliding block, a guide column is fixedly installed at the end of the square block, a spring is sleeved on the outer wall of the guide column, a connecting rod is slidingly installed in the square block, and a locking block corresponding to the limiting block is fixedly installed at the end of the connecting rod.

[0007] By adopting the above technical solution, it is ensured that the locking block can smoothly restrict the two ejector pin fixing plates through the limiting block, avoiding the use of screws. At the same time, through the use of guide pillars, springs and connecting rods, the user can smoothly drive the ejector pin fixing plate to slide in the mold base when using the ejector pin, thereby ensuring that the ejector pin fixing plate can smoothly push the ejector pin. Meanwhile, with the setting of springs and connecting rods, the ejector pin fixing plate can smoothly reset under the guidance of the guide pillar.

[0008] Furthermore, two sets of the limiting blocks are symmetrically arranged on the outer wall of the ejector pin fixing plate, and the limiting blocks are located at the center of the outer wall of the ejector pin fixing plate.

[0009] By adopting the above technical solution, it is ensured that the limiting block can better drive the ejector pin fixing plate to slide within the mold base.

[0010] Furthermore, two sets of square blocks are symmetrically arranged on the outer wall of the mold base, and the slider is located at the bottom of the square blocks.

[0011] By adopting the above technical solution, it is ensured that the square block slides smoothly on the outer wall of the mold base under the transmission of the slider.

[0012] Furthermore, two sets of sliders are symmetrically arranged at the bottom of the square block, and the sliders are slidably connected to the sliding rods.

[0013] By adopting the above technical solution, the sliding of the square block on the outer wall of the mold base is made more stable.

[0014] Furthermore, both ends of the guide post are fixedly connected to the square block, and the guide post passes through the connecting rod.

[0015] By adopting the above technical solution, it is ensured that the connecting rod can slide up and down regularly within the square block.

[0016] Furthermore, one end of the spring is attached to the inner wall of the square block, and the other end is attached to the outer wall of the connecting rod, with the spring located on the outer wall of the connecting rod away from the slider.

[0017] By adopting the above technical solution, it is ensured that the spring-pressed connecting rod can be smoothly reset.

[0018] Furthermore, two sets of guide posts are symmetrically arranged within the square block, and the outer wall of the square block is provided with a sliding groove corresponding to the connecting rod.

[0019] By adopting the above technical solution, it is ensured that the connecting rod can smoothly drive the locking block to start moving.

[0020] Furthermore, locking blocks are fixedly installed at both ends of the connecting rod, and the locking blocks have grooves corresponding to the limiting blocks.

[0021] By adopting the above technical solution, it is ensured that the locking block can smoothly move the ejector pin fixing plate and drive the connecting rod to move.

[0022] In summary, the present invention has the following main advantages:

[0023] This invention incorporates a limiting block, a locking block, a bidirectional lead screw, a transmission groove, a sliding rod, a slider, and a square block. Through the transmission groove, the slider slides within the mold base, causing the locking block to slide against the outer wall of the limiting block. This locking block restricts the limiting block, ensuring that the locking block can smoothly restrain the two ejector pin fixing plates, eliminating the need for screws. Furthermore, the use of guide posts, springs, and connecting rods allows the user to smoothly drive the ejector pin fixing plates to slide within the mold base when using the ejector pins, ensuring that the ejector pin fixing plates can smoothly push the ejector pins. Simultaneously, with the springs and connecting rods, the ejector pin fixing plates smoothly reset under the guidance of the guide posts. Attached Figure Description

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0031] The embodiments of this utility model will be described below based on its overall structure.

[0032] A die-casting apparatus for processing castings, such as Figure 1 - Figure 5 As shown, the mold includes a mold base 1 and an ejector pin fixing plate 2. A limiting block 3 is fixedly installed on the outer wall of the ejector pin fixing plate 2. Two sets of ejector pin fixing plates 2 overlap, causing the limiting blocks 3 to overlap with each other. A bidirectional lead screw 4 is rotatably installed inside the mold base 1, and a sliding rod 42 is fixedly installed inside the mold base 1. A transmission groove 41 is opened at the end of the bidirectional lead screw 4. A slider 5 is threadedly installed on the outer wall of the bidirectional lead screw 4. By rotating the transmission groove 41, the bidirectional lead screw 4 starts to rotate, and then the slider 5 moves on the outer wall of the bidirectional lead screw 4. A square block 6 is fixedly installed on the outer wall of the slider 5. The movement of the slider 5 drives the square block 6 to slide on the outer wall of the mold base 1. A guide post 7 is fixedly installed at the end of the square block 6. A spring 8 is sleeved on the outer wall of the guide post 7. A connecting rod 9 is slidably installed inside the square block 6, and a locking block 31 corresponding to the limiting block 3 is fixedly installed at the end of the connecting rod 9. When the ejector pin fixing plate 2 slides inside the mold base 1, the locking block 31 is driven to slide simultaneously through the limiting block 3, thereby driving the connecting rod 9 to slide inside the square block 6.

[0033] Please see Figure 5 Two sets of limiting blocks 3 are symmetrically arranged on the outer wall of the ejector pin fixing plate 2, and the limiting blocks 3 are located at the center of the outer wall of the ejector pin fixing plate 2. As the two sets of ejector pin fixing plates 2 overlap, the limiting blocks 3 overlap with each other at the same time, ensuring that the limiting blocks 3 can better drive the ejector pin fixing plate 2 to slide in the mold base 1.

[0034] Please see Figure 1 and Figure 2 Two sets of square blocks 6 are symmetrically arranged on the outer wall of the mold base 1. The two sets of square blocks 6 slide on the outer wall of the mold base 1, and the slider 5 is located at the bottom of the square blocks 6. The sliding of the slider 5 drives the square blocks 6 to slide on the outer wall of the mold base 1, ensuring that the square blocks 6 slide smoothly on the outer wall of the mold base 1 under the transmission of the slider 5.

[0035] Please see Figure 4 Two sets of sliders 5 are symmetrically arranged at the bottom of the square block 6, and the sliders 5 are slidably connected to the slide rod 42. One set of sliders 5 is threadedly connected to the bidirectional lead screw 4, and the other set of sliders 5 is slidably connected to the slide rod 42, so that the sliders 5 on the outer wall of the bidirectional lead screw 4 move on the outer wall of the bidirectional lead screw 4. Through the transmission of the square block 6, the other set of sliders 5 is driven to slide on the outer wall of the slide rod 42, ensuring that the sliding of the square block 6 on the outer wall of the mold base 1 is more stable.

[0036] Please see Figure 2 Both ends of the guide post 7 are fixedly connected to the square block 6, and the guide post 7 passes through the connecting rod 9. Under the guidance of the guide post 7, the connecting rod 9 begins to slide within the square block 6, ensuring that the connecting rod 9 can slide up and down regularly within the square block 6.

[0037] Please seeFigure 2 One end of the spring 8 is attached to the inner wall of the square block 6, and the other end is attached to the outer wall of the connecting rod 9. By the compression of the connecting rod 9, the spring 8 begins to contract inside the square block 6, and the spring 8 is located on the outer wall of the connecting rod 9 away from the slider 5, ensuring that the connecting rod 9 can be smoothly reset by the compression of the spring 8.

[0038] Please see Figure 2 Two sets of guide posts 7 are symmetrically arranged inside the square block 6. The two sets of guide posts 7 can better guide the sliding of the connecting rod 9. The outer wall of the square block 6 is provided with a sliding groove corresponding to the connecting rod 9. The movement of the connecting rod 9 drives the locking block 31 to move at the same time, ensuring that the connecting rod 9 can smoothly drive the locking block 31 to start moving.

[0039] Please see Figure 2 and Figure 3 Locking blocks 31 are fixedly installed at both ends of the connecting rod 9, and the locking blocks 31 have grooves corresponding to the limiting blocks 3. When the locking blocks 31 and the limiting blocks 3 are engaged, the movement of the ejector pin fixing plate 2 drives the locking blocks 31 to slide through the limiting blocks 3, thereby driving the connecting rod 9 to squeeze the spring 8 in the square block 6, ensuring that the locking blocks 31 can smoothly move the ejector pin fixing plate 2 to drive the connecting rod 9 to move.

[0040] The working principle of this utility model is as follows: When installing the ejector pin fixing plate 2, the user first overlaps the two sets of ejector pin fixing plates 2 together, so that the limiting blocks 3 on the outer walls of the two sets of ejector pin fixing plates 2 overlap each other. At this time, the user can install the ejector pin fixing plate 2 on the outer wall of the mold base 1. At this time, the user can drive the bidirectional lead screw 4 to start rotating inside the mold base 1 through the transmission groove 41. At this time, the two sets of sliders 5 threadedly connected to the bidirectional lead screw 4 start to move towards the center of the mold base 1, thereby driving the locking block 31 to start moving until the end of the locking block 31 coincides with the end of the limiting block 3. Under the continuous drive of the user, the limiting block 3 starts to slide on the inner wall of the locking block 31, thereby restricting the limiting block 3 with the locking block 31, avoiding the user's operation of fixing with screws.

[0041] When the user pushes the ejector pin using the ejector pin fixing plate 2, the push of the ejector pin fixing plate 2 drives the limiting block 3 on the outer wall of the ejector pin fixing plate 2, thereby causing the locking block 31 to slide on the outer wall of the mold base 1. Due to the setting of the connecting rod 9, the connecting rod 9 slides in the square block 6, thereby compressing the spring 8. At this time, under the movement of the ejector pin fixing plate 2, the ejector pin begins to push the part in the mold, thereby allowing the part to be smoothly pushed out of the mold. At this time, the user can stop applying force to the ejector pin fixing plate 2 and start pushing the connecting rod 9 under the action of the spring 8, thereby causing the connecting rod 9 to slide on the outer wall of the guide post 7. At this time, driven by the spring 8, the ejector pin fixing plate 2 is reset by the movement of the connecting rod 9 and the sliding of the locking block 31.

The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
