Description

Technical Field

[0001] The utility model relates to the field of molds, in particular to an injection mold forming device. Background Art

[0002] Injection molding is also known as injection molding. It is a molding method that combines injection and molding. The advantages of the injection molding method are fast production speed, high efficiency, automated operation, a wide variety of colors, shapes from simple to complex, sizes from large to small, and precise product sizes. The products are easy to update and can be made into parts with complex shapes. Injection molding is suitable for mass production and molding processing fields such as products with complex shapes. At a certain temperature, the completely molten plastic material is stirred by a screw, injected into the mold cavity with high pressure, and the molded product is obtained after cooling and solidification. This method is suitable for mass production of parts with complex shapes and is one of the important processing methods. Molds are various molds and tools used in industrial production to obtain the desired products by injection molding, blow molding, extrusion, die casting or forging molding, smelting, stamping, etc. Molds are tools used to make molded objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the object by changing the physical state of the molded material.

[0003] The existing injection mold forming device processes it into a desired shape through the injection mold forming device, which often only requires changing the shape of the mold. During injection molding, it is necessary to wait for the mold to cool before taking out the product inside, otherwise it will cause product damage.

[0004] When the steamer frame is injection molded, it is designed in a trapezoidal shape. After molding, it will be mounted on the outer wall of the protrusion. There are two ways to demould, one is to remove it manually, and the other is to eject it from the outer wall of the protrusion with an ejector pin. However, the ejected product will fall directly, and the product that has just been demoulded may lack toughness and be easily damaged by falling. Utility Model Content

[0016] The utility model is further configured that a sliding rod is installed at the end of the oblique rod.

[0017] By adopting the above technical solution, the sliding rod at the end can move diagonally when moving, thereby achieving the function of lifting and lowering the force-bearing plate.

[0018] The utility model is further configured that a slide rail is fixed on the top of the workbench.

[0019] By adopting the above technical solution, the friction between the second support plate and the workbench can be reduced when the second support plate moves.

[0020] The utility model is further configured that the material of the movable plate is rubber material.

[0021] By adopting the above technical solution, the product can be protected and the newly demoulded product can be prevented from being damaged by collision due to insufficient toughness.

[0022] In summary, the utility model mainly has the following beneficial effects:

[0023] The utility model solves the problem that the mold is easily damaged, dented or even deformed when it falls by providing a connecting rod, a sliding block, a rack and a gear. The connecting rod drives the rack and the gear to engage, thereby driving the cross bar and the diagonal bar connected thereto to slide to both sides under the action of the top slide groove, driving the force plate to rise and fall, so that the mold can fall on the force plate when the mold is opened, avoiding the mold from being broken due to excessive drop when it falls. When the force plate moves downward, the movable plate will flip, so that the product that falls on the movable plate will fall, reducing the drop when the product falls, and protecting the product.

A cross bar 8 is connected to one side of the slider 6, and inclined rods 17 are installed at both ends of the cross bar 8. A sliding rod 23 is movably installed at the end of the inclined rod 17, and a fixed block 11 is provided on the outer wall of the sliding rod 23. A force plate 16 is fixed on the top of the fixed block 11, and a gear 19 is movably installed on the top of the movable plate 15.

[0032] See also Figure 4 A movable plate 15 is movably installed on one side of the force-bearing plate 16, a fixing rod 7 is fixed on the top of the workbench 5, and a through hole 22 is opened at the bottom of the force-bearing plate 16. When the force-bearing plate 16 descends, the fixing rod 7 located at the bottom of the force-bearing plate 16 will push the movable plate 15 out through the through hole 22, causing it to tilt to one side, thereby reducing the drop when the product falls and protecting the product.

[0033] See also Figure 1-Figure 4A slider groove 18 is provided on the top of the workbench 5, and the inner wall of the slider groove 18 fits with the outer wall of the slider 6. When the injection mold is working, the slider 6 at the top of the bottom of the workbench 5 will move inside the slider groove 18, and the slider groove 18 fits with the inner wall of the slider 6, preventing the slider 6 from moving in other directions during movement.

[0034] See also Figure 4 There are four inclined rods 17 in two groups. The middle parts of the two inclined rods 17 are connected by a rotating shaft. The two inclined rods 17 are arranged in an x ​​shape. When the inclined rods 17 move, they will drive the force plate 16 to rise and fall. The two groups of inclined rods 17 are arranged in an x ​​shape to make it more firmly fixed and greatly increase the carrying capacity.

[0035] See also Figure 1 and Figure 4 A slide groove 12 matching the slide rod 23 is provided at the bottom of the fixed block 11. When the force-bearing plate 16 is lifted or lowered, the slide rod 23 arranged at the bottom can move in a directional manner in the slide groove 12, driving the inclined rod 17 to lift or lower.

[0036] See also Figure 4 A sliding rod 23 is installed at the end of the inclined rod 17. When the inclined rod 17 moves, the sliding rod 23 at its end moves, thereby achieving the function of lifting and lowering the force-bearing plate 16.

[0037] See also Figure 1 A slide rail 24 is fixed on the top of the workbench 5. When the injection mold device is working, the second support plate 3 will move through the telescopic rod 2. The slide rail 24 is set on the top of the workbench 5 to reduce the friction between the second support plate 3 and the workbench 5.

[0038] See also Figure 1 The material of the movable plate 15 is rubber. When the product is completed, the ejector 21 will eject it and drop it on the movable plate 15. The surface of the movable plate 15 is set to rubber material, which can protect the product and prevent the newly demoulded product from being damaged by collision due to insufficient toughness.

[0039] The working principle of the utility model is as follows: when the injection mold molding device starts to work, the telescopic rod 2 drives the second support plate 3 to move forward, thereby driving the connecting rod 4 to move forward, so that the upper mold 9 moves forward, and at the same time the connecting rod 4 drives the slider 6 to move forward. At this time, the racks 20 at the bottom of the two groups of sliders 6 will mesh with the internal gears 19, thereby achieving relative movement. The inclined rod 17 connected to one side of the slider 6 will slide along the slide groove 12 inside the fixed block 11 under the action of the slider 6, thereby driving the force plate 16 to descend. At this time, the convex block 10 is closed with the lower mold 14. When the convex block 10 is opened, the telescopic rod 2 drives the second support plate 3 to move forward, thereby driving the upper mold 9 to move forward, and at the same time the connecting rod 4 drives the slider 6 to move forward. The retracting rod 2 and the connecting rod 4 move backward, thereby driving the upper mold 9 and the slider 6 to move backward. At this time, the slider 6 drives the inclined rod 17 to slide to the middle under the meshing of the rack 20 and the gear 19, so that the force plate 16 moves upward. At this time, the ejector 21 will eject the mold and land on the surface of the movable plate 15. Then the injection mold molding device continues to move forward, and the force plate 16 moves downward. At this time, the fixed rod 7 under the force plate 16 contacts the movable plate 15 through the through hole 22, and the movable plate 15 will flip over, so that the product falling on the movable plate falls and the mold falls, thereby avoiding damage to the mold.
