Description

Technical Field

[0001] The utility model relates to the technical field of injection molding machines, in particular to an adjustable blanking device for injection molding machines. Background Art

[0002] Injection molding utilizes the thermophysical properties of plastics to plasticize, melt, and homogenize the material before injecting it into the mold cavity. The molten material is then pressure-maintained, cooled, and solidified in the mold cavity to form the finished product. Injection molding requires an injection molding machine.

[0003] The injection molding machines currently in use include a head plate, a second plate, a tail plate, and a Green column. The head plate and the second plate are opposite to each other and are fixedly installed with a fixed plate and a movable plate respectively. The second plate can slide on the Green column, and the position of the second plate is locked by the oil cylinder and the machine hinge assembly to achieve mold locking. After the injection molding is completed, the oil cylinder drives the second plate to move away from the head plate through the machine hinge assembly, so that the movable plate moves away from the fixed plate, the mold is opened, and the injection-molded product falls. In order to better receive the product, a receiving box is generally placed under the injection molding machine or the product is guided outward to the conveyor belt through a receiving plate. However, the sizes of the movable plate and the fixed plate are different, resulting in different product drop heights. When the product contacts the receiving box or the receiving plate, a reaction force is generated and the product is separated from the receiving box or the receiving plate, which brings great inconvenience to use.

In the description of the present invention, it should be understood that the directions or positional relationships indicated by directional terms such as "upper, lower" and "top, bottom" are generally based on the directions or positional relationships shown in the accompanying drawings and are intended only to facilitate the description of the present invention and simplify the description. Unless otherwise indicated, these directional terms do not indicate or imply that the devices or components referred to must have a specific direction or be constructed and operated in a specific direction, and therefore should not be understood as limiting the scope of protection of the present invention; the directional terms "inside" and "outside" refer to the inside and outside relative to the outline of each component itself.

[0025] like Figure 1-8 As shown, an adjustable blanking device for an injection molding machine includes a telescopic blanking frame and a guide plate 1;

[0026] The telescopic blanking frame includes an outer frame 2 and an inner frame 3. The outer frame and the inner frame are both U-shaped and open to the same side. The inner frame is slidably fitted in the outer frame. The lower end of the outer frame has a mounting plate 4 extending outward. The mounting plate has a mounting hole 5. A height locking structure is also provided between the outer frame and the inner frame.

[0027] The inner frame is rotatably mounted with a rotating shaft 6, which is located at one end of the inner frame away from the opening. The rotating shaft is fixedly connected to one end of the guide plate, and support structures are installed between both sides of the opening end of the inner frame and the guide plate.

[0028] In this way, when in use, the mounting plate is fixedly connected to the injection molding machine, or the mounting plate is fixedly installed on the ground. The telescopic blanking frame is adjusted according to the height of the blanking material required. After adjustment into place, it is locked by the height locking structure. At the same time, the inclination angle of the guide plate is adjusted according to the height of the conveyor belt set at the outer end of the guide plate, so that the lower end of the guide plate faces the conveyor belt, which is convenient for the product to fall onto the guide plate after the mold is opened and then slide down to the conveyor belt along the guide plate, which is convenient for blanking.

[0029] By setting the outer frame and the inner frame, the height and position of the material guide plate can be easily adjusted, and the installation and use are convenient.

[0030] During implementation, the upper end of the outer frame has a flange 7 protruding outward, and the upper end of the inner frame has a lap 8 protruding outward, and the lap is overlapped on the flange, so as to facilitate the positioning and support of the inner frame.

[0031] During implementation, the overlapped edge is fixedly mounted with a guide post 9, and the flange is penetrated with a guide hole 10 that is slidably matched with the guide post, so as to guide the movement of the inner frame.

[0032] During implementation, the height locking structure includes a locking rod 11 fixedly installed at the lower end of the overlap, a through hole 12 is provided on the flange to allow the locking rod to pass through, a plurality of locking holes 13 are provided on the locking rod, a mounting seat 14 is fixed downward on the flange, a locking pin 15 is slidably fitted on the mounting seat, a locking handle 16 is fixed on the outside of the locking pin, a locking tension spring 17 is sleeved on the locking pin, one end of the locking tension spring is fixed to the locking handle, and the other end of the locking tension spring is fixed to the mounting seat, a ring 18 is fixed on the outer frame opposite to the locking pin, and the locking pin passes through the locking hole and is plugged into the ring.

[0033] In this way, according to the desired height of the inner frame, the locking handle is pulled outward to disengage the locking hole and collar. The inner frame can then be moved under the action of the guide column. Once in position, the handle is released, and the locking spring resets, driving the locking pin through the locking hole and into the collar, locking the height of the inner frame. The injection molded part is lightweight and slides directly after falling onto the guide plate without stopping on the guide plate. Therefore, the inner frame can be locked relative to the outer frame using the height locking structure.

[0034] In practice, the support structure includes elastic pins 19 mounted on either side of the guide plate. The inner frame is provided with a plurality of support holes 20 on either side that engage with the elastic pins. The support holes are arranged coaxially with the rotating shaft. Inserting the elastic pins into the support holes facilitates locking the angle of the guide plate. The coaxial arrangement of the support holes with the rotating shaft facilitates rotation of the support plate to adjust its angle. After the rotating shaft is rotatably connected to the inner frame and the guide plate is installed, the inner frame is connected to the outer frame.

[0035] During implementation, the elastic pin comprises a vertical plate fixedly mounted on the material guide plate, the vertical plate having a sliding hole extending therethrough, a support pin slidably engaged within the sliding hole, the support pin being capable of plugging into the support hole, a support handle fixed to the end of the support pin, a support tension spring sleeved on the outer side of the support pin, the ends of the support tension spring being fixedly connected to the support handle and the vertical plate, respectively. The elastic pin has an existing structure and is easy to use.

[0036] Finally, it should be noted that those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims and their equivalents, the present invention is intended to include such modifications and variations.
