Description

Technical Field

[0001] This utility model relates to the field of modular box molds, specifically a high-efficiency modular box mold with a fast demolding effect. Background Technology

[0002] In the electronics field, module boxes, as standardized components (used in the production of smart meters), directly affect the assembly progress of downstream industries through their production efficiency and product quality. As core production equipment, the demolding performance of module box molds is a key factor determining the production cycle and the finished product qualification rate. Currently, module box molds have significant technical defects in terms of demolding efficiency, product integrity, and adaptability.

[0003] Traditional modular box molds often use a single ejection demolding mechanism (such as push rod ejection or top plate ejection), which has obvious efficiency bottlenecks: long demolding time: for complex modular boxes with side holes and bosses, a single ejection mechanism needs to complete the demolding action in steps (first loosen the side buckles, then eject the bottom), poor coordination of demolding action: in multi-cavity molds, the synchronization error between the ejector pin and the cavity can reach 0.5-1mm, causing some cavities to be demolded late, requiring manual assistance to peel off; vacuum adsorption hinders demolding: after the modular box is formed, it fits tightly with the cavity wall. If the mold is not properly vented, a local vacuum will be formed, which will increase the demolding resistance and affect the efficiency and practicality of the demolding operation.

[0004] Traditional demolding methods suffer from uneven stress and structural defects, resulting in low product yield rates. Excessive localized stress leads to deformation. In ejector-type demolding, the small contact area between the ejector pin and the module box results in high stress per unit area, causing ejector pin marks, localized dents, tearing, and scratches on the edges and corners. For module boxes with right angles or reinforcing ribs, the fixed pulling angle of traditional side-pulling mechanisms can easily cause edge tearing if the pulling speed is too fast, while excessively slow pulling leads to over-cooling, causing the product to stick to the cavity, increasing the surface scratch rate, and making it prone to misalignment or wobbling when the upper and lower mold frames are assembled, resulting in a significant reduction in workpiece production quality. Therefore, it is necessary to design a high-efficiency module box mold with a fast demolding effect to solve the above problems. Utility Model Content

[0023] Example 1

[0024] Please refer to Figures 1-5 As shown, this utility model provides a high-efficiency module box mold with a fast demolding effect, including a module box body 1. A mold cover plate 2 is provided on the top of the body 1. The mold cover plate 2 is fixed to the top of the body 1 by a positioning component to prevent the mold cover plate 2 from shifting when splicing with the body 1 to form a mold cavity. A push mold frame 3 is installed inside the body 1 and near the bottom. The top of the body 1 is spliced ​​and snapped with the mold cover plate 2 for processing the mold. A pressing component for placing the push mold frame 3 to move upward is installed inside the push mold frame 3 and near both sides. A demolding component for fast demolding is installed inside the push mold frame 3.

[0025] In addition, the mold cover plate 2 on the top of the main body 1 is spliced ​​and installed vertically. The push mold frame 3 has an "I" shaped cross section. The push mold frame 3 slides up and down inside the main body 1. The top of the main body 1 and the bottom of the mold cover plate 2 form a workpiece cavity. The lower pressure component can lock and fix the push mold frame 3. The push mold frame 3 supports the main body 1 and the mold cover plate 2 upward. The push mold frame 3 can push the workpiece on the top of the main body 1 upward for demolding. The demolding component inside the push mold frame 3 can push the workpiece upward, and at the same time, gas can be injected to accelerate the demolding rate.

[0026] Specifically, the pressing component includes movable cavities 4 respectively opened on both sides of the body 1. A fixing tube 5 is fixedly installed on the top of the inner side of the movable cavity 4. A fixing rod 6 is slidably installed on the inner side of the fixing tube 5 near one end. The other end of the fixing rod 6 is fixedly connected to the push mold frame 3. A first spring 7 is fitted on the outer side of the fixing tube 5. Bolts are screwed to both sides of the body 1 to lock and fix the push mold frame 3. An anti-detachment part 18 is fixedly connected to one end of the fixing rod 6. The anti-detachment part 18 is slidably connected to the fixing tube 5 and does not detach.

[0027] Limiting strips extend from both sides of the push mold frame 3 to prevent it from detaching from the movable cavity 4. The fixing tube 5 can slide up and down with the fixing rod 6. The anti-detachment part 18 at the top of the fixing rod 6 can prevent the fixing rod 6 from detaching from the fixing tube 5. The first spring 7 on the outside of the fixing tube 5 can push the push mold frame 3 downward, so that the push mold frame 3 fits into the bottom of the workpiece cavity, reducing the formation of burrs on the workpiece. Bolts can be used to lock and fix the push mold frame 3 and the body 1, improving the convenience and stability of installing the push mold frame 3.

[0028] More specifically, the demolding component includes an installation cavity 8 located at the center of the inner side of the push mold frame 3. A sliding rod 9 is slidably connected to the inner side of the installation cavity 8. A demolding template 10 is fixedly connected to the top of the sliding rod 9. A notch for placing the demolding template 10 is opened at the top of the push mold frame 3 and at the top of the installation cavity 8. The demolding component also includes a pad 11 fixedly connected to the outer side of the sliding rod 9 and near the upper middle part. A second spring 12 is fitted on the outer side of the sliding rod 9. An air supply pipe 13 is installed on the other side of the installation cavity 8. The two ends of the second spring 12 are fixedly connected to the installation cavity 8 and the pad 11, respectively. The other end of the air supply pipe 13 can be connected to an external air pump. A pressing plate 19 is fixedly connected to the bottom of the sliding rod 9. A groove 20 for placing the pressing plate 19 is opened at the bottom of the installation cavity 8.

[0029] Additionally, the second spring 12 inside the mounting cavity 8 can press the pad 11 downwards, causing the pad 11 to drive the demolding template 10 at the top of the sliding rod 9 to embed into the notch, reducing the formation of burrs on the workpiece. The pressing plate 19 at the bottom of the sliding rod 9 is in the groove 20, preventing the pressing plate 19 from extending too far and affecting the support of the mold ejector 3 on the body 1. Air is supplied to the mounting cavity 8 and the bottom of the cavity through an air pump connected to one end of the air supply pipe 13 to accelerate the airflow and push the workpiece to demold, avoiding mechanical pushing that could damage the workpiece, and also speeding up the demolding operation.

[0030] Furthermore, the positioning component includes multiple positioning holes 14 evenly arranged on both sides of the mold cover plate 2, positioning posts 15 fixedly installed on the top of the body 1 and near both sides, and three sets of star bolts 16 screwed onto both sides of the body 1, with a locking groove 17 on one side of the positioning post 15 to provide fixing space for the star bolts 16, and each set of star bolts 16 includes two.

[0031] The positioning pin 15 can be embedded in the positioning hole 14 to position the mold cover plate 2, preventing the mold cover plate 2 from shifting with the body 1. The star bolt 16 is inserted into the positioning pin 15 to lock and fix the mold cover plate 2, thereby improving the stability of the workpiece forming process.

[0032] Working principle: First, by pushing the pressing plate 19, the pressing plate 19 drives the top of the sliding rod 9, the demolding template 10, to move upward within the notch. At the same time, the sliding rod 9 drives the pad 11 to press the second spring 12 upward, so that the workpiece and the cavity form a space. Then, the air pump supplies air to the mounting cavity 8 through the air supply pipe 13. The air supports the workpiece more evenly and can also push the uncontacted part of the demolding template 10 to demold.

[0033] When the workpiece is over-fitted and difficult to demold, the bolt is rotated to move the top of the push mold frame 3 upward within the body 1. At the same time, the first spring 7 is compressed and deformed, and the fixing rod 6 slides within the fixing tube 5 to expand the area on which the push mold frame 3 pushes the workpiece, so that the top of the push mold frame 3 pushes the workpiece upward to demold it.

[0034] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0035] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
