Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, specifically to a spring steel elastic ejection mold. Background Technology

[0002] In the existing technology, at the ejector pin outlet, an elastic cavity is formed inside the ejector pin made of spring steel to generate elastic force. Since the elastic cavity is located close to the ejector step, the ejector pin will shift away from the ejector step, thereby improving the ejection effect. During the mold closing process, the front mold and the rear mold cooperate to perform a closing motion, thereby pushing the ejector pin along the mold closing direction of the mold to reset it, achieving the purpose of resetting the ejector pin.

[0016] Compared with the prior art, the advantages of this utility model are as follows: 1. When this utility model is used, the external screw conveyor puts the molten raw material into the material port of the fixed mold through the material port. Under the limit of the fixed mold, the moving mold one, the elastic ejection component and the translational ejection component, the product body is cooled and formed. After the product body is formed, the external cylinder drives the moving mold two to move down, the moving mold two drives the moving mold one to move down, the moving mold one separates from the fixed mold, the moving mold one drives the elastic ejection component and the translational ejection component to move down, the elastic ejection component and the translational ejection component separate from the fixed mold. During the downward movement, the elastic ejection component and the translational ejection component are translated to the outside of the moving mold one due to the limit, so that the elastic ejection component and the translational ejection component no longer squeeze the product body. At this time, the external cylinder pushes the ejector plate to move up, the ejector plate drives the ejector rod to move up, and ejects the product body, realizing the elastic ejection component and the translational ejection component to eject elastically when the mold is opened, which is convenient for subsequent material feeding.

[0017] 2. When this utility model is used, if mold opening is required, the external cylinder drives the moving mold 2 and moving mold 1 to move downwards. The moving mold 1 drives the sliding block to move downwards. The sliding block 1 moves obliquely along the sliding post 1 through the inclined groove 1, so that the sliding block 1 moves outwards along the sliding groove 1 while moving downwards. The sliding block 1 drives the sliding rod to move outwards along the sliding groove 2. The sliding block 1 drives the bolt to move outwards along the fixing plate. The spring gradually compresses from the stretched state, so that when the sliding post 1 is completely separated from the sliding block 1, the sliding block 1... The spring's elasticity remains in its current position; when mold closing is required, the external cylinder moves the moving mold 2 and moving mold 1 upwards, the bottom end of the sliding post 1 enters the inclined groove 1 and moves along the inclined groove 1, thereby moving the sliding block 1 inwards along the slide groove 1, the sliding block 1 moves the sliding rod inwards along the slide groove 2, the sliding block 1 moves the bolt inwards, the spring is stretched, until the fixed mold and the moving mold 1 are completely fitted together; the end of the slide groove 2 that faces each other in the front and back directions forms the groove 2 when the product body is formed;

[0018] 3. When this utility model is used, if mold opening is required, the external cylinder drives the moving mold 2 and the moving mold 1 to move downwards. The moving mold 1 drives the sliding block 2 to move downwards. The sliding block 2 moves obliquely along the sliding post 2 through the inclined groove 2, so that the sliding block 2 moves outwards along the sliding groove 3 while moving downwards. The sliding block 2 drives the slider to move outwards along the sliding groove 4. The two sets of limiting blocks move closer to each other along the sliding groove 5, so that the side of the limiting block away from the slider no longer squeezes the product body, so as to facilitate material unloading. If mold closing is required, the external cylinder drives the moving mold 2 and the moving mold 1 to move upwards.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0032] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0033] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-9 A spring steel elastic ejection mold includes a fixed mold 1, a moving mold 2, a translational shaping assembly 3 for shaping product slots, a second moving mold 4, an ejector plate 5, and an ejector rod 6. The translational shaping assembly 3 includes an elastic ejection assembly 31 and a translational ejection assembly 32. The elastic ejection assembly 31 is mounted on the upper part of the moving mold 2 and connected to the fixed mold 1. The translational ejection assembly 32 is mounted on the upper part of the moving mold 2 and... The fixed mold 1 is connected to the moving mold 2 via a sliding rod. The lower end of the moving mold 2 is fixedly connected to the moving mold 4. The ejector plate 5 is slidably connected to the moving mold 2 via a sliding rod. The side wall of the ejector plate 5 is slidably connected to the moving mold 4. The ejector rod 6 is fixedly installed on the upper end of the ejector plate 5. The outer wall of the ejector rod 6 is slidably connected to the moving mold 2. The fixed mold 1 is connected to an external screw conveyor. The moving mold 4 and the ejector plate 5 are respectively connected to an external cylinder.

[0034] The fixed mold 1, the moving mold 1 2, the elastic ejection component 31, and the translational ejection component 32 work together to generate two sets of product bodies 7 from the molten raw material. The left side of the product body 7 has a slot 1 71, the lower left side of the product body 7 has two sets of slots 2 72, the right side of the product body 7 has two sets of opposite slots 3 73, the front and rear sides of the product body 7 have slots 4 74, the right side of the product body 7 has slot 5 75, and the lower left middle of the product body 7 has slot 6 76.

[0035] In use, this invention involves an external screw conveyor feeding molten raw material through the inlet of the fixed mold 1. Under the constraints of the fixed mold 1, moving mold 2, elastic ejector assembly 31, and translational ejector assembly 32, the raw material is cooled to form the product body 7. After the product body 7 is formed, an external cylinder moves the moving mold 4 downwards, which in turn moves the moving mold 2 downwards. The moving mold 2 separates from the fixed mold 1, and the moving mold 2 moves the elastic ejector assembly 31 and translational ejector assembly 32 downwards. The elastic ejector assembly 31 and translational ejector assembly 32 then detach from the fixed mold 1. During the downward movement of the ejector assembly 31 and the translational ejector assembly 32, due to the limiting position, they move to the outer periphery of the moving mold 1 2, so that the elastic ejector assembly 31 and the translational ejector assembly 32 no longer squeeze the product body 7. At this time, the external cylinder pushes the ejector plate 5 to move upward, and the ejector plate 5 drives the ejector rod 6 to move upward, ejecting the product body 7. This realizes the elastic ejector assembly 31 and the translational ejector assembly 32 elastically ejecting when the mold is opened, which facilitates subsequent material unloading. The connecting block between the fixed mold 1 and the moving mold 1 2 forms the slot 1 71 and the slot 6 76 when the product body 7 is formed.

[0036] The elastic ejection assembly 31 is provided in four sets. The two sets of elastic ejection assemblies 31 on the front side and the two sets of elastic ejection assemblies 31 on the rear side are symmetrically distributed about the center of the fixed mold 1. The two sets of elastic ejection assemblies 31 on the left side and the two sets of elastic ejection assemblies 31 on the right side are symmetrically distributed about the center of the fixed mold 1.

[0037] The elastic ejection assembly 31 includes a bolt 311, a spring 312, a fixing plate 313, a sliding block 314, a sliding rod 316, and a sliding post 318. The threaded end of the bolt 311 is threadedly connected to the sliding block 314. Both ends of the spring 312 are connected to the bolt 311 and the fixing plate 313. The outer wall of the bolt 311 is slidably connected to the fixing plate 313. The fixing plate 313 is fixedly installed on the outer wall of the moving mold 2. A groove 3 is provided on the upper part of the moving mold 2. 15. The inner wall of slide block 314 is limited and slidably connected to slide groove 315. The end of slide block 314 away from bolt 311 is fixedly connected to slide rod 316. The interior of moving mold 2 is provided with slide groove 317. The outer wall of slide rod 316 is limited and slidably connected to slide groove 317. The upper part of slide post 318 is fixedly connected to fixed mold 1. The interior of slide block 314 is provided with inclined groove 319. Inclined groove 319 is limited and slidably connected to the outer wall of slide post 318.

[0038] One end of the spring 312 is fixedly connected to the bolt 311, and the other end of the spring 312 is fixedly connected to the fixing plate 313.

[0039] When this utility model is in use, if mold opening is required, an external cylinder drives the moving mold 2 4 and moving mold 1 2 to move downwards. Moving mold 1 2 drives the sliding block 314 to move downwards. Sliding block 314 moves obliquely along sliding post 318 through inclined groove 319, so that sliding block 314 moves outwards along sliding groove 315 while moving downwards. Sliding block 314 drives sliding rod 316 to move outwards along sliding groove 317. Sliding block 314 drives bolt 311 to move outwards along fixing plate 313. Spring 312 is gradually compressed from a stretched state, so that when sliding post 318 is completely disengaged from sliding block 314, sliding block 314... 4. Due to the elastic effect of spring 312, the mold remains in its current position. When mold closing is required, the external cylinder drives the moving mold 2 4 and moving mold 1 2 to move upward. The bottom end of the sliding post 318 enters the inclined groove 319 and moves along the inclined groove 319, thereby driving the sliding block 314 to move inward along the sliding groove 315. The sliding block 314 drives the sliding rod 316 to move inward along the sliding groove 2 317. The sliding block 314 drives the bolt 311 to move inward. The spring 312 is stretched until the fixed mold 1 and the moving mold 1 2 are completely fitted together. The end of the sliding groove 2 317 that is close to each other in the front and back directions forms the groove 2 72 when the product body 7 is formed.

[0040] The translational ejection assembly 32 is provided in two sets and is symmetrically distributed about the center of the fixed mold 1.

[0041] The translational ejection assembly 32 includes a sliding block 321, a sliding post 323, a slider 324, a limiting block 325, and a limiting post 328. The upper part of the moving mold 2 has a sliding groove 322, and the sliding block 321 is slidably connected to the inner wall of the sliding groove 322. The upper part of the sliding post 323 is fixedly connected to the fixed mold 1. The interior of the sliding block 321 has an inclined groove 329, which is slidably connected to the outer wall of the sliding post 323. One end of the second position block 321 near the center of the moving mold 2 is fixedly connected to the slider 324. The end of the limiting block 325 near the slider 324 is provided with a sliding groove 326. The side wall of the slider 324 is slidably connected with the sliding groove 326. The upper part of the moving mold 2 is provided with a sliding groove 327. The side wall of the limiting block 325 is slidably connected with the sliding groove 327 in the front and rear directions. The limiting post 328 is fixedly installed on the upper part of the moving mold 2 and located near the limiting block 325.

[0042] The limiting block 325 and the slide groove 326 are provided in two sets and are symmetrically distributed about the center of the moving mold 2.

[0043] The limiting posts 328 are provided in two sets and are symmetrically distributed about the center of the moving mold 2.

[0044] When this utility model is in use, if mold opening is required, the external cylinder drives the moving mold 2 4 and moving mold 1 2 to move downwards. Moving mold 1 2 drives the sliding block 2 321 to move downwards. Sliding block 2 321 moves obliquely along sliding post 2 323 through inclined groove 2 329, so that while moving downwards, sliding block 2 321 moves outwards along sliding groove 3 322. Sliding block 2 321 drives slider 324 to move outwards along sliding groove 4 326. Two sets of limiting blocks 325 move closer to each other along sliding groove 5 327, so that the side of limiting block 325 away from slider 324 no longer squeezes the product body 7, so as to facilitate material unloading. If mold closing is required, the external cylinder drives the external cylinder to move downwards. Moving mold 2 and moving mold 1 move upwards, the bottom end of sliding post 2 323 enters inclined groove 2 329 and moves along inclined groove 2 329, thereby driving sliding block 2 321 to move inward along sliding groove 3 322. Sliding block 2 321 drives slider 324 to move inward along sliding groove 4 326. Sliding block 324 drives limiting block 325 to move away from each other along sliding groove 5 327 until fixed mold 1 and moving mold 1 2 are completely fitted together. Limiting post 328 forms groove 4 74 when product body 7 is formed. The side of slider 324 and limiting block 325 near the center of moving mold 1 2 protrudes and forms groove 5 75 when product body 7 is formed.

[0045] Example 2: In some embodiments, such as Figure 6 and Figure 7 As shown; in a preferred embodiment of the present invention, the outer wall protrusion of the limiting block 325 near the center of the moving mold 2 is set as rectangular.

[0046] When this utility model is used, the rectangular protrusion on the outer wall of the limiting block 325 forms a groove 73 when the product body 7 is formed.

[0047] Example 3: In some embodiments, such as Figures 3-5 As shown, in a preferred embodiment of this utility model, the material of both the first row post 318 and the second row post 323 is spring steel.

[0048] When this utility model is used, the spring steel material gives slide post 318 and slide post 323 good elasticity, mechanical properties and fatigue performance, thus enabling them to play a better role in mold operation.
