Description

Technical Field

[0001] This utility model relates to the field of plastic mold technology, and in particular to a fast-discharge type plastic mold. Background Technology

[0002] Plastic molds are a type of combined mold used in compression molding, extrusion molding, injection molding, blow molding, and low-foaming molding. The coordinated changes in the mold's punch, die, and auxiliary molding systems allow for the production of a range of plastic parts of different shapes and sizes.

[0003] Plastic molds are typically made by joining two molds together to form a complete mold. Liquid plastic is then injected into the joined mold, allowing it to fill the entire mold and gradually form a solid object. After molding, the plastic workpiece often sticks to the mold, making it difficult to remove. Current technology usually incorporates an ejector mechanism inside the mold to push the workpiece out from the inside. However, if the workpiece is tightly adhered to the mold, a single ejection attempt may not be successful, requiring multiple attempts, which can easily damage the workpiece. Furthermore, the ejection mechanism leaves marks on the surface of the workpiece, affecting its aesthetics. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a fast-discharge plastic mold, which solves the problem mentioned in the background art that usually a push structure is set inside the mold to push the molded workpiece out from the inside. However, if the molded workpiece is tightly adhered to the mold, it cannot be successfully ejected in one go and multiple ejection operations are required, which can easily lead to workpiece damage. In addition, the surface of the ejected workpiece will have the mark of the ejection structure, which affects the appearance of the workpiece.

Detailed Implementation

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Please see Figures 1-5 This utility model provides a technical solution: a fast-discharge plastic mold, including a crossbeam plate 2, fixed support columns 3, a lower mold 4, and a fixed base plate 5. The lower mold 4 is arranged on the left side of the upper surface of the fixed base plate 5. Fixed support columns 3 are arranged on the surface of the fixed base plate 5 around the lower mold 4. The crossbeam plate 2 is arranged at the upper end of the fixed support rod 9. A hydraulic cylinder 1 is mounted on the upper side of the crossbeam plate 2. The output end of the hydraulic cylinder 1 is connected to the upper mold 7. Supports 8 are arranged on both the left and right sides of the upper surface of the fixed base plate 5. The supports 8 are connected to the fixed base plate 5 through the fixed support rod 9. A guide rail 6 is arranged between the two sets of supports 8. A material picking slide 10 is arranged inside the guide rail 6. Connecting arms 12 are provided on the front and rear sides. Pneumatic sliders 13 are installed at the connection between the connecting arms 12 and the guide rail 6. A first support plate 14 is provided on the lower side of the material picking slide plate 10. A second support plate 17 is provided on the lower side of the first support plate 14. A suction cup 18 is embedded on the bottom surface of the second support plate 17. This design solves the problem that the original plastic mold has an internal push structure, which pushes the molded workpiece out from the inside. However, if the molded workpiece is tightly stuck to the mold, it cannot be successfully ejected in one go and multiple ejection operations are required, which can easily lead to damage to the workpiece. In addition, the surface of the ejected workpiece will have the mark of the ejection structure, which affects the appearance of the workpiece.

[0022] Multiple sets of suction cups 18 are provided, and the multiple sets of suction cups 18 are evenly arranged on the lower side of the second support plate 17. The suction cups 18 are connected to external pneumatic equipment through air pipes. The multiple sets of suction cups 18 can adsorb the workpiece in the lower mold 4 from multiple positions, so that the workpiece is subjected to uniform force and it is convenient to remove the workpiece.

[0023] The first support plate 14 has the same specifications as the second support plate 17. Supporting rods 16 are provided at the left and right connection points of the connection between the first support plate 14 and the second support plate 17. The lower end of the supporting rod 16 is fixed to the second support plate 17. A return spring 15 is sleeved on the outside of the supporting rod 16. The supporting rod 16 facilitates the connection between the first support plate 14 and the second support plate 17, and the return spring 15 can buffer the second support plate 17, thereby providing buffer protection for the workpiece when it is adsorbed.

[0024] Guide rods 71 ​​are provided on both the left and right sides of the upper end face of the upper mold 7, and the guide rods 71 ​​penetrate through the crossbeam plate 2. A plug 72 is provided at the upper end of the guide rod 71. The diameter of the plug 72 is larger than the diameter of the guide rod 71. The guide rods 71 ​​play a guiding and limiting role in the movement of the upper mold 7.

[0025] The distance between the two sets of guide rails 6 is greater than the longitudinal width of the lower mold 4. The guide rails 6 are located between the lower mold 4 and the crossbeam plate 2, and the initial height of the suction cup 18 is higher than the height of the workpiece surface inside the lower mold 4, which improves the rationality of the design and will not interfere with the opening and closing of the upper mold 7 and the lower mold 4.

[0026] A pneumatic cylinder 11 is mounted on the upper side of the material handling slide plate 10, and the first support plate 14 is connected to the output end of the pneumatic cylinder 11. The pneumatic cylinder 11 can drive the first support plate 14 to move up and down, thereby driving the suction cup 18 to move up and down, so that the suction cup 18 can be adsorbed or detached from the workpiece.

[0027] As an embodiment of this utility model: In actual use, firstly, the hydraulic cylinder 1 is controlled to drive the upper mold 7 to move upward, so that the upper mold 7 separates from the lower mold 4, realizing mold opening. Then, the pneumatic slider 13 drives the material picking slide 10 to move to the left along the guide rail 6, so that the material picking slide 10 moves directly above the upper mold 7. Then, the pneumatic cylinder 11 drives the first support plate 14 and the second support plate 17 to move downward, so that the suction cup 18 is attached to the surface of the workpiece in the lower mold 4. The workpiece is adsorbed by the suction cup 18. Then, the pneumatic cylinder 11 drives the support plate to move upward, so that the workpiece is taken out from the lower mold 4. Then, the material picking plate is controlled to move to the right with the workpiece, and then the workpiece is taken off from the suction cup 18, thus completing the quick and convenient material picking operation of the workpiece.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model.
