Technical Field

[0001] This utility model relates to the field of injection molding machine technology, specifically to an injection molding machine mold changing mechanism. Background Technology

[0002] Injection molding is a method of shaping industrial products. Products are usually made using rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding compression molding and die casting. An injection molding machine, also known as an injection molding machine or injection machine, is the main molding equipment that uses plastic molds to make plastic products of various shapes from thermoplastic or thermosetting plastics. It is divided into vertical, horizontal and all-electric types. The injection molding machine can heat the plastic and apply high pressure to the molten plastic, causing it to be injected and fill the mold.

[0003] When using an injection molding machine, if the mold is damaged or does not meet production requirements, it needs to be replaced. However, existing injection molding machine molds are generally fixed to the equipment with screws, and disassembling the mold requires unscrewing multiple sets of bolts, which reduces replacement efficiency.

[0004] In view of this, the present invention proposes a mold changing mechanism for injection molding machines. Utility Model Content

[0005] This utility model proposes an injection molding machine mold replacement mechanism, which solves the problem that when a mold is damaged or does not meet production requirements, it needs to be replaced. However, existing injection molding machine molds are generally fixed to the equipment with screws, and multiple sets of bolts need to be unscrewed when disassembling the mold, which reduces the replacement efficiency.

[0006] The technical solution of this utility model is as follows: A mold changing mechanism for an injection molding machine includes a base, a mold body inserted into the base, insertion holes on both sides of the mold body, grooves inside the base on both sides of the mold body, an insert plate slidably connected to the base and embedded in the insertion hole inside the groove, a screw threadedly connected to the base on one side of the insert plate, slide rods fixedly connected to the insert plate at both ends of the screw rod, a limiting ring fixedly connected to the base slidably connected to the surface of the slide rod, and a baffle fixedly connected to the base by screws above the groove.

[0007] Preferably, a side plate is fixedly connected to the back of the base, an electric push rod is fixedly connected to the surface of the side plate, a feeding plate is fixedly connected to the output end of the electric push rod, and a receiving platform is fixedly connected to the surface of the base.

[0008] Preferably, when the mold body is embedded inside the base, all surfaces are in close contact with the base, and the insert plate is vertically inserted into the insertion hole and adapted to its size.

[0009] Preferably, the tail of the screw passes through the base and extends to the outer side of the base.

[0010] Preferably, the surface of the slide rod is in contact with the inner ring of the limiting ring, and the slide rod slides horizontally along the limiting ring under the action of the screw.

[0011] Preferably, the insert plate, screw, and slide bar are all hidden inside the groove, and the baffle completely covers the top of the groove.

[0012] Preferably, when the feed plate moves above the mold body, its bottom is in contact with the top of the mold body.

[0013] Preferably, the receiving platform has a "U" shaped structure, and the length of the receiving platform is greater than that of the mold body.

[0014] The working principle and beneficial effects of this utility model are as follows:

[0015] 1. In this utility model, when the mold body needs to be replaced by setting the insert plate, the screw can be rotated to apply a pulling force to the insert plate, thereby controlling the slide bar to slide away from the mold body along the inside of the limiting ring. When the insert plate slides out of the groove, the mold body loses the locking effect of the insert plate, and the mold body can be pulled out upwards to achieve the purpose of quick disassembly. The components that control the locking of the mold body are all hidden inside the groove, which can avoid the parts being exposed to the outside and enhance the overall effect of the equipment.

[0016] 2. In this utility model, by setting a feeding plate, when the formed mold is ejected from the mold body by the ejector pin, the electric push rod can be opened to push the feeding plate forward, pushing the ejected workpiece to the receiving table, realizing automatic feeding operation, which facilitates the equipment to carry out the next round of production.

[0023] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model. Example 1

[0024] A preferred embodiment of the injection molding machine mold changing mechanism provided by this utility model is as follows: Figures 1 to 4 As shown: A mold changing mechanism for an injection molding machine includes a base 1, a mold body 2 inserted inside the base 1, insertion holes 3 on both sides of the mold body 2, and grooves 4 located inside the base 1 on both sides of the mold body 2. Insert plates 5 are slidably connected to the base 1 and embedded in the insertion holes 3 inside the grooves 4. A screw 6 threadedly connected to the base 1 is rotatably connected to one side of the insert plate 5. Slide rods 7 fixedly connected to the insert plate 5 are provided at both ends of the screw 6. Limiting rings 8 fixedly connected to the base 1 are slidably connected to the surface of the slide rods 7. A baffle 9 fixedly connected to the base 1 by screws is provided above the grooves 4.

[0025] In this embodiment, when the mold body 2 is embedded in the base 1, all surfaces are tightly fitted to the base 1. The insert plate 5 is vertically inserted into the insertion hole 3 and is adapted to its size. When the insert plate 5 slides out of the groove 4, the mold body 2 loses the locking effect of the insert plate 5, and the mold body 2 can be pulled out upwards to achieve the purpose of quick disassembly.

[0026] In this embodiment, the tail of the screw 6 passes through the base 1 and extends to the outer side of the base 1. The screw 6 can be rotated to apply a pulling force to the insert plate 5, thereby controlling the slide bar 7 to slide along the inside of the limiting ring 8 to the side away from the mold body 2.

[0027] In this embodiment, the surface of the slide rod 7 is in contact with the inner ring of the limiting ring 8. Under the action of the screw 6, the slide rod 7 slides horizontally along the limiting ring 8. Under the action of the limiting ring 8, the movement trajectory of the insert plate 5 can be limited, so that it slides horizontally away from the insertion hole 3.

[0028] In this embodiment, the insert plate 5, screw 6 and slide bar 7 are all hidden inside the groove 4, and the baffle 9 completely covers the top of the groove 4. All components that control the engagement of the mold body 2 are hidden inside the groove 4, which can prevent parts from being exposed to the outside and enhance the overall effect of the equipment. Example 2

[0029] Based on Embodiment 1, a preferred embodiment of the injection molding machine mold changing mechanism provided by this utility model is as follows: Figures 1 to 4 As shown: a side plate 10 is fixedly connected to the back of the base 1, an electric push rod 11 is fixedly connected to the surface of the side plate 10, a feeding plate 12 is fixedly connected to the output end of the electric push rod 11, and a receiving platform 13 is fixedly connected to the surface of the base 1.

[0030] In this embodiment, when the unloading plate 12 moves above the mold body 2, its bottom is in contact with the top of the mold body 2. The unloading plate 12 can be pushed forward by opening the electric push rod 11, which pushes the ejected workpiece onto the receiving table 13, thereby realizing the automatic unloading operation.

[0031] In this embodiment, the receiving platform 13 has a "U" shaped structure. The length of the receiving platform 13 is greater than that of the mold body 2. The baffles 9 on both sides of the receiving platform 13 can block the workpiece and prevent it from falling off the receiving platform 13.

[0032] The working principle and usage process of this utility model are as follows: First, when it is necessary to replace the mold body 2, the screw 6 can be rotated to apply a pulling force to the insert plate 5, thereby controlling the slide bar 7 to slide along the inside of the limiting ring 8 to the side away from the mold body 2. When the insert plate 5 slides out of the inside of the groove 4, the mold body 2 loses the locking effect of the insert plate 5, and the mold body 2 can be pulled out upwards to achieve the purpose of quick disassembly. The components that control the locking of the mold body 2 are all hidden inside the groove 4, which can prevent the parts from being exposed to the outside and enhance the overall effect of the equipment. When the formed mold is ejected from the inside of the mold body 2 by the ejector pin, the electric push rod 11 can be opened to push the unloading plate 12 forward, pushing the ejected workpiece onto the receiving table 13 to realize the automatic unloading operation, which facilitates the equipment to carry out the next round of production.

[0033] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
