Description

Technical Field

[0001] This utility model specifically relates to the field of injection mold technology, and more specifically to an injection mold with a guiding material ejection structure. Background Technology

[0002] Injection molds are tools used for plastic molding. By injecting molten plastic into the mold cavity, it is cooled and solidified to form a product of a specific shape. When using injection molds, they need to be installed in an injection molding machine. Plastic granules are heated and melted in the injection molding machine barrel. The molten plastic is injected into the mold cavity under high pressure, so that it forms a specific shape according to the inner cavity of the mold. Then, the plastic is cooled and solidified by a temperature control system. Finally, the mold is opened and the ejector mechanism pushes out the molded product.

[0003] However, in practice, it has been noted that injection molds require high temperatures to melt materials during processing, and the materials need to be cooled after molding. Due to the short cooling time, the internal temperature of the molded workpiece remains high. Therefore, when unloading, the internal temperature of the molded workpiece is transferred to the surface, resulting in a still high surface temperature. Furthermore, when manually handling the material, workers are prone to touching the mold surface, which can easily cause burns to their hands, resulting in poor safety. Utility Model Content

[0004] The purpose of this invention is to provide an injection mold with a guiding material discharge structure. When the mold closing mechanism of the injection molding machine separates the two injection molds, the injection mold will move one end of the rotating guide hopper upwards via a connecting rod until the end of the rotating guide hopper moves between the two injection molds, guiding the material falling from the injection molds. The material slides off the outside of the equipment through the guidance of the rotating guide hopper and the fixed inclined hopper, eliminating the need for manual material removal, making it convenient and quick. This solves the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: An injection mold with a guiding discharge structure includes an injection molding machine body, an injection molding machine mold closing mechanism installed in the injection molding machine body, and an injection mold symmetrically fixedly connected to the inner side of the injection molding machine mold closing mechanism. Each of the aforementioned injection molds is movably connected to a connecting rod at its bottom, and a discharge guide is also provided at the bottom of the injection mold, wherein the discharge guide includes a fixed inclined hopper and a rotating guide hopper connected together by hinges.

[0006] As a further technical solution of this utility model, the end of the rotary guide hopper away from the fixed inclined hopper is symmetrically and movably connected to a U-shaped pin plate corresponding to the connecting rod, and one end of the connecting rod is movably connected to the U-shaped pin plate, and the other end is movably connected to the bottom of the injection mold.

[0007] As a further technical solution of this utility model, the bottom of the fixed inclined hopper is integrally provided with a connecting slide, and the connecting slide is symmetrically provided with sliding holes, and a supporting slide rod passes through each of the sliding holes.

[0008] As a further technical solution of this utility model, the support slide rod is located below the mold closing mechanism of the injection molding machine, and both ends of the support slide rod are fixedly connected to the main body of the injection molding machine, and the support slide rod is slidably engaged with the sliding hole.

[0009] As a further technical solution of this utility model, a feed hopper is fixedly connected to the top of the injection molding machine body, and the end of the fixed inclined hopper away from the rotating guide hopper extends to the side of the injection molding machine body.

[0010] Compared with the prior art, the beneficial effects of this utility model are: In this invention, a fixed inclined hopper and a rotary guide hopper are respectively located below the injection mold, and the fixed inclined hopper and the rotary guide hopper are inclined. After the injection mold is opened, the ejection mechanism inside the mold will eject the workpiece, and the workpiece will fall into the inclined fixed inclined hopper and the rotary guide hopper, thereby guiding the workpiece to fall into the collection box placed in advance at the end of the fixed inclined hopper. There is no need for manual handling of the workpiece, which improves the safety of material discharge. In this invention, the end of the rotary guide hopper away from the fixed inclined hopper is movably connected to the lower part of the injection mold via a connecting rod. When the two injection molds are closed, the connecting rod pushes the end of the rotary guide hopper downward to rotate, preventing the discharge guide from affecting the normal closing of the injection mold. When the two injection molds are separated, the injection mold will drive the end of the rotary guide hopper to lean against the injection mold via the connecting rod, so that the rotary guide hopper is close to the lower part between the two injection molds, ensuring that the falling workpiece can be accurately caught. In this invention, the fixed tilting hopper slides above the supporting slide rod via a connecting slide block at the bottom, allowing the fixed tilting hopper to adjust its position and thus improve the accuracy of receiving workpieces.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-6 This utility model embodiment provides an injection mold with a guiding material discharge structure, including an injection molding machine body 1, an injection molding machine mold closing mechanism 3 installed in the injection molding machine body 1, and an injection mold 4 symmetrically fixedly connected to the inner side of the injection molding machine mold closing mechanism 3; Each injection mold 4 is movably connected to a connecting rod 7 below it, and a discharge guide 5 is also provided below the injection mold 4. The discharge guide 5 includes a fixed inclined hopper 51 and a rotating guide hopper 52 connected together by hinges.

[0020] Furthermore, the rotating guide hopper 52 is symmetrically and movably connected to a U-shaped pin plate 53 corresponding to the connecting rod 7 at one end away from the fixed inclined hopper 51, and one end of the connecting rod 7 is movably connected to the U-shaped pin plate 53, while the other end is movably connected to the bottom of the injection mold 4.

[0021] By adopting the above technical solution, the fixed inclined hopper 51 and the rotary guide hopper 52 are respectively set below the injection mold 4, and the fixed inclined hopper 51 and the rotary guide hopper 52 are set at an inclination. After the injection mold 4 is opened, the ejection mechanism inside the mold will eject the workpiece, and the workpiece will fall into the inclined fixed inclined hopper 51 and the rotary guide hopper 52, thereby guiding the workpiece to fall into the collection box placed in advance at the end of the fixed inclined hopper 51. There is no need for manual handling of the workpiece, which improves the safety of material discharge.

[0022] More specifically, the bottom of the fixed inclined hopper 51 is integrally provided with a connecting slide 54, and the connecting slide 54 is symmetrically provided with sliding holes 55, and a supporting slide rod 6 passes through each of the sliding holes 55.

[0023] Furthermore, the support slide rod 6 is located below the mold closing mechanism 3 of the injection molding machine, and both ends of the support slide rod 6 are fixedly connected to the main body 1 of the injection molding machine, and the support slide rod 6 is slidably engaged with the sliding hole 55.

[0024] Furthermore, a feed hopper 2 is fixedly connected to the top of the injection molding machine body 1, and the end of the fixed inclined hopper 51 away from the rotating guide hopper 52 extends to the side of the injection molding machine body 1.

[0025] By adopting the above technical solution, the end of the rotary guide hopper 52 away from the fixed inclined hopper 51 is movably connected to the lower part of the injection mold 4 through the connecting rod 7. When the two injection molds 4 are closed, the end of the rotary guide hopper 52 is pushed downward by the connecting rod 7 to prevent the discharge guide 5 from affecting the normal closing of the injection mold 4. When the two injection molds 4 are separated, the injection mold 4 will drive the end of the rotary guide hopper 52 to lean against the injection mold 4 through the connecting rod 7, so that the rotary guide hopper 52 is close to the lower part between the two injection molds 4, ensuring that the falling workpiece can be accurately received.

[0026] Furthermore, the injection molding machine clamping mechanism 3 includes a fixed side plate and a movable side plate, and the fixed side plate is fixedly connected with positioning slide rods in a rectangular array on the side of the movable side plate. The movable side plate and the positioning slide rods are slidably engaged, and the two injection molds 4 are symmetrically fixedly connected between the fixed side plate and the movable side plate.

[0027] Furthermore, an electric push rod is fixedly connected to the side of the movable side plate. The electric push rod pushes the movable side plate to slide in the positioning slide rod, thereby driving the injection mold 4 between the fixed side plate and the movable side plate to close or separate.

[0028] By adopting the above technical solution, the fixed inclined hopper 51 slides on the support slide rod 6 through the connecting slide block 54 at the bottom, so that the fixed inclined hopper 51 can slide above the support slide rod 6, adjust the position of the fixed inclined hopper 51, and thus improve the accuracy of receiving workpieces.

[0029] More specifically, the main body 1 of the injection molding machine is also equipped with a spiral extrusion mechanism, and a heating mechanism is installed on the outside of the spiral extrusion mechanism. One end of the spiral extrusion mechanism is connected to the feed hopper 2, and the other end passes through the fixed side plate and is connected to the cavity inside the injection mold 4. The screw extrusion mechanism pushes the plastic granules in the feed hopper 2, and the heating mechanism on the outside melts the plastic granules. The screw extrusion mechanism then sends the molten plastic granules to the injection mold 4 for injection molding.

[0030] The working principle of this utility model is as follows: First, plastic granules are poured into the feed hopper 2. The heating mechanism in the main body 1 of the injection molding machine melts the plastic granules. Then, the pressure propulsion mechanism sends the molten plastic granules into the inner side of the injection mold 4 for processing and shaping. During discharge, the mold closing mechanism 3 of the injection molding machine moves one of the injection molds 4, separating the two injection molds 4. Simultaneously, the injection mold 4 drives the end of the rotating guide hopper 52 to rotate upwards via the connecting rod 7 below. The moving injection mold also drives the fixed inclined hopper 51 to slide above the support slide rod 6, thus moving the rotating guide hopper 52 below the two injection molds 4. After the workpiece falls above the rotating guide hopper 52, the rotating guide hopper 52 and the fixed inclined hopper 51 cooperate to guide the produced workpiece, causing it to fall into the collection box placed beforehand below the end of the fixed inclined hopper 51. The structure is simple, the operation is very convenient, and it effectively reduces the intensity of manual labor.
