Description

Technical Field

[0001] The utility model relates to injection molding mold equipment. Background Art

[0002] Injection mold equipment, also known as injection molding machine or die-casting machine, is a device that heats and melts plastic or metal materials, injects the molten plastic into the mold through an injection device, and obtains the desired plastic product after cooling and molding.

[0003] The molds of existing horizontal injection mold equipment are divided into a fixed mold and a movable mold. The fixed mold and the movable mold are arranged horizontally. External pressure is applied to the fixed mold and the movable mold so that the two are tightly abutted. After the corresponding material fluid is injected inside, the product is formed under high pressure.

[0004] However, the existing recycling of products after molding still has major problems. The reason is that there is residual heat on the surface of the molded product. If it is recycled manually, it will cause safety hazards. If an automated recycling method such as a robot is used, it will greatly increase the manufacturing cost. In addition, if the product is directly removed and falls into the recycling tank under its own gravity, the kinetic energy generated by the free fall is large, which may cause the edges and corners of the newly molded product to be damaged and produce defects. Utility Model Content

[0005] The utility model aims to provide an injection molding mold device, which can automatically recycle the molded products, reduce the distance the products fall, and reduce the occurrence of product defects.

[0006] The above technical objectives of the utility model are achieved through the following technical solutions:

[0007] An injection molding mold device includes: a frame, an injection system is arranged on one side of the frame; a positioning rod is arranged on one side of the frame; two sliding seats are slidably connected to the positioning rod; hinged rods are respectively hinged on the two sliding seats, and the two hinged rods are hinged; a connecting rod is hinged at the middle of each hinged rod; a push plate is hinged to the connecting rod; an output rod is connected to the push plate; a hydraulic cylinder is connected to the output rod and is used to drive the output rod to move up and down; a fixed mold is connected to the sliding seat close to one side of the injection system; a movable mold is connected to the end of the injection system; and a material receiving box is arranged below between the fixed mold and the movable mold.

[0008] The utility model is further configured to include: a positioning plate, which is fixedly sleeved on the output rod; a traction rope, one end of which is fixedly connected to the positioning plate; a roller, which is arranged in cooperation with the middle part of the traction rope; a rotating shaft, which passes through the middle part of the roller and is connected to the frame bearing; and the other end of the traction rope is connected to the material receiving box.

[0009] The utility model is further configured to include: a fixed frame connected to one side of the material receiving box for sliding the material receiving box; a slide groove arranged on the fixed frame; and a sliding block connected to the material receiving box and corresponding to the slide groove.

[0010] The utility model is further configured to include: a sliding plate, which is arranged at the bottom of the material receiving box; a T-shaped groove, which is arranged at the bottom of the material receiving box; a T-shaped block, which is arranged on the sliding plate and corresponds to the T-shaped groove; and a gripping portion, which is arranged at one side of the sliding plate.

[0011] The utility model is further configured that: when the hydraulic cylinder drives the output rod to move upward, the fixed mold and the movable mold abut against each other and perform injection; when the hydraulic cylinder drives the output rod to move downward, the fixed mold and the movable mold are separated and the material receiving box moves upward.

[0012] The utility model is further configured that: the sliding plate is pulled outward by the gripping part to open the bottom of the material receiving box, and the product falls from the bottom of the material receiving box.

[0013] In summary, the utility model has the following beneficial effects:

[0014] 1. Automatic recycling function: The equipment can automatically recycle the formed products without manual operation, which improves production efficiency and safety.

[0015] 2. Reduce product damage: The design of the liftable receiving box reduces the drop distance of the product from the mold to the receiving box, thereby reducing the collision kinetic energy between the product and the receiving box, effectively preventing the product from being damaged during the recycling process.

[0016] 3. Easy to take out the product: A sliding plate is designed at the bottom of the receiving box to facilitate the one-time removal of the collected products and facilitate subsequent inspection and packaging.

[0017] 4. Improve safety: Since there is residual temperature on the surface of the product after molding, the automatic recycling method avoids direct manual contact with high-temperature products and reduces safety hazards.

[0018] 5. Reduce defective products: By reducing the product drop distance and collision intensity, the possibility of product defects such as damaged corners is reduced, which helps to improve product quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "page", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0027] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0028] In the description of the present utility model, "multiple" means two or more than two, unless otherwise clearly specified and specifically defined. In the present utility model, unless otherwise clearly specified and defined, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal connection of two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances.

[0029] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0030] like Figure 1 , Figure 2 As shown, an injection molding mold device includes a frame 1. An injection system 2 is arranged on one side of the frame 1. The injection system 2 includes components such as a screw, a hopper, and a press. The main function of the injection system 2 is to push the material entering the hopper into the screw for transportation, melt the material during transportation, and finally inject it into the mold through a nozzle. The above-mentioned injection system 2 is a prior art, so it is not repeated.

[0031] The core technical solution of this application is as follows:

[0032] like Figure 1 , Figure 3 , Figure 4 As shown, in order to solve the problem of automatically recovering products and reducing the distance that products fall, the present application is provided with a positioning rod 3 on one side of the frame 1. Two sliding seats 4 are slidably connected to the positioning rod 3. Both sliding seats 4 are hinged with articulated rods 5. The articulated rods 5 are hinged. A connecting rod 6 is hinged at the middle of each articulated rod 5. The connecting rod 6 extends downward and is hinged with a propulsion plate 7. The propulsion plate 7 is connected to an output rod 8. The output rod 8 is connected to a hydraulic cylinder 9 for driving the conveying rod to move up and down.

[0033] In the above, taking the upward movement of the output rod 8 as an example, when the output rod 8 moves upward under the action of the hydraulic cylinder 9, it drives the push plate 7 to move upward, thereby driving the connecting rod 6 hinged to the push plate 7 to swing to both sides, and when the push plate 7 swings, it drives the hinged rod 5 to move in the opposite direction to both sides, thereby driving the sliding seat 4 to move in the opposite direction. Similarly, when the output rod 8 moves downward, the two sliding seats 4 can move toward each other.

[0034] Furthermore, the sliding seat 4 near the injection system 2 is connected to the fixed mold 10, and correspondingly, the end of the injection system 2 is connected to the movable mold 11. When the hydraulic cylinder 9 drives the output shaft to move upward, the fixed mold 10 and the movable mold 11 can be tightly abutted. At this time, the injection system 2 injects material fluid into the product area formed between the fixed mold 10 and the movable mold 11 to complete the injection process.

[0035] Optimized, a positioning plate 12 is fixedly sleeved on the output rod 8. A traction rope 13 is fixedly connected to one side of the positioning plate 12. The traction rope 13 can be made of rubber with relatively high strength. A roller 14 is arranged in the middle of the traction rope 13. A rotating shaft 15 is passed through the middle of the roller 14. The rotating shaft 15 is connected to the frame 1 by a bearing. One end of the traction rope 13 passing through the outer surface of the roller 14 is connected to a material receiving box 16. The material receiving box 16 is arranged below the fixed mold 10 and the movable mold 11. A fixed frame 17 is connected to one side of the material receiving box 16 for the material receiving box 16 to slide. A slide groove 18 is arranged on the fixed frame 17, and correspondingly, a slider 19 is connected to the material receiving box 16 corresponding to the slide groove 18. The slider 19 limits the position of the material receiving box 16, so that the material receiving box 16 is limited to move up and down.

[0036] The above working process is as follows: when the hydraulic cylinder 9 drives the output rod 8 to move upward, the fixed mold 10 abuts against the movable mold 11 and performs injection. When the hydraulic cylinder 9 drives the output rod 8 to move downward, the fixed mold 10 separates from the movable mold 11. At this time, the positioning plate 12 drives the traction rope 13 to move downward, so that the other end of the traction rope 13 pulls the material receiving box 16 upward, so that the longitudinal distance between the material receiving box 16 and the fixed mold 10 and the movable mold 11 is reduced. When the fixed mold 10 separates from the movable mold 11, the product detaches from the fixed mold 10, so that the product falls into the material receiving box 16 for recovery.

[0037] Under the above setting, the product automatically escapes from the fixed mold 10 and enters the material receiving box 16 for recovery. On the basis of automatic recovery, the material receiving box 16 is brought close to the product to reduce the distance the product falls, thereby reducing the collision kinetic energy between the product and the material receiving box 16 and preventing the product from being damaged.

[0038] like Figure 5 , Figure 6 As shown, in an optimized manner, a sliding plate 20 is provided at the bottom of the material receiving box 16. A T-shaped slot 21 is provided at the bottom of the material receiving box 16. Correspondingly, a T-shaped block 22 is provided on the sliding plate 20 corresponding to the T-shaped slot 21. The T-shaped block 22 can slide in the T-shaped slot 21. A gripping portion 23 for pulling the sliding plate 20 is also provided on one side of the sliding plate 20.

[0039] After a large number of products are stored in the receiving box 16, the sliding plate 20 can be pulled outward by the gripping portion 23, so that the bottom of the receiving box 16 is opened and the products fall from the bottom of the receiving box 16, thereby taking the products out at one time for subsequent inspection and packaging processes.
