Description

Technical Field

[0001] This utility model relates to the technical field of injection molded parts, and in particular to a cooling device for injection molding. Background Technology

[0002] Injection molded products are made by heating and plasticizing plastic with an injection molding machine, then injecting it into the cavity of a mold to form a molded product. After cooling and solidification, the melt is demolded. Therefore, a cooling device for injection molding is particularly needed.

[0003] The automotive injection molding part cooling mechanism, authorized by announcement number CN222858684U, includes a cooling box. A filter screen for placing the injection molded part is provided inside the cooling box. A drive motor is mounted on one side of the cooling box via a mounting bracket. A transmission mechanism is mounted on the drive motor and the cooling box. The transmission mechanism includes a lifting unit and a cooling unit. The lifting unit provides power for the up-and-down movement of the filter screen. The cooling unit improves the heat dissipation efficiency of the cooling water. This invention, through the transmission mechanism, allows the injection molded part to be cooled to be placed on the filter screen using a drive motor. The up-and-down movement of the filter screen moves the injection molded part into the water. Then, the gear and the last movable block on the rack are in contact but not meshing, continuously driving the second rotating wheel and blades to rotate, thus circulating the cooling water, increasing the contact area between the cooling water and air, and dissipating heat from the cooling water, thereby improving the heat dissipation efficiency of the injection molded part. However, in the aforementioned automotive injection molding cooling mechanism, although the injection molded parts that need to be cooled can be placed on the filter screen, after the filter screen descends and moves the injection molded parts into the water, the blades in the device cause the cooling water to move, and the injection molded parts will fluctuate with the water. The collision of the injection molded parts with each other will affect the quality of the product molding.

[0004] To address the aforementioned problems, a cooling device for injection molding is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a cooling device for injection molding, so as to solve the problems of the existing cooling devices for injection molding mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a cooling device for injection molding, comprising a cooling box, a filter screen provided on the inner wall of the cooling box, side plates provided on both sides of the filter screen, a movable plate provided at the top of the side plates, a first guide rod installed between the side plates, and adjusting rods provided on both sides of the movable plate.

[0007] Preferably, the top of the movable plate is provided with seven sets of guide grooves, one end of the first guide rod is fitted with seven sets of clamps, and the clamps are slidably connected to the first guide rod. A silicone layer is glued between the opposing surfaces of the clamps, and a guide post is installed on the top of the end of the clamp away from the first guide rod.

[0008] Preferably, a sliding bearing is installed on one end wall of the side plate, and a mounting plate is installed on the other end of the side plate, with positioning bolts bolted to the inner wall of the mounting plate.

[0009] Preferably, a top plate is welded to both sides of the top of the cooling box, and a second guide rod is provided between the cooling box and the top plate. The second guide rod passes through the top of the side plate and is slidably connected to the side plate.

[0010] Preferably, the guide groove at the center of the movable plate is set in the same horizontal direction as the clamping plate, and three sets of guide grooves are respectively inclined on both sides of the guide groove at the center of the movable plate, and the opening direction is in the shape of an "eight".

[0011] Preferably, the surface of the adjusting rod away from the movable plate has a threaded structure, and the end of the adjusting rod has a multi-tooth structure. The end of the adjusting rod away from the movable plate passes through the sliding bearing and the side plate respectively, and the threaded structure on the surface of the adjusting rod is threadedly connected to the inner wall of the side plate.

[0012] Preferably, the bottom of the positioning bolt engages with the toothed groove at the end of the adjusting rod.

[0013] Preferably, the guide post passes through the guide groove and is slidably connected to the guide groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. When the adjusting rod is rotated, the seven sets of clamps slide laterally along the first guide rod, causing the clamps to move laterally. The clamps flexibly hold the injection molded parts through the silicone layer, avoiding the workpiece from floating with the water flow in the traditional cooling method. The buffering effect of the silicone layer can absorb the impact force generated by the fluctuation of the cooling medium, preventing the injection molded parts from colliding with each other or with the inner wall of the cooling box, fundamentally eliminating quality defects such as surface scratches and flash deformation caused by collisions. 2. The guide groove on the movable plate allows the clamping plate to adjust the clamping distance according to the size of the injection molded part, so that injection molded parts of different specifications can be stably fixed during cooling, avoiding floating and collision caused by differences in workpiece shape.

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0018] Example like Figure 1-3 As shown, the device includes a cooling box 1, a filter screen 2 on the inner wall of the cooling box 1, side plates 3 on both sides of the filter screen 2, a movable plate 4 at the top of the side plates 3, a first guide rod 5 between the side plates 3, adjusting rods 6 on both sides of the movable plate 4, seven sets of guide grooves 7 on the top of the movable plate 4, seven sets of clamping plates 8 passing through the surface of the adjusting rods 6, a silicone layer 9 glued between the opposing surfaces of the clamping plates 8, a guide post 10 installed at one end of the clamping plate 8, a sliding bearing 11 installed on one end wall of the side plate 3, and an installation plate 12 installed at the other end of the side plate 3. A positioning bolt 13 is bolted to the inner wall of the installation plate 12.

[0019] It should be noted that in this embodiment, the injection molding module is first placed between the clamping plates 8, and then the position of the clamping plates 8 is adjusted. Since the surface of the adjusting rod 6 away from the movable plate 4 is threaded and is threadedly connected to the inner wall of the side plate 3, when the end of the adjusting rod 6 is rotated clockwise, the front end of the adjusting rod 6 is connected to the movable plate 4. The adjusting rod 6 moves in the side plate 3 through the threaded transmission, and the movable plate 4 moves in the direction of the first guide rod 5. When the movable plate 4 moves, the seven sets of guide grooves 7 on it move synchronously. The clamping plates 8 are slidably connected to the guide grooves 7 through the guide post 10. Since the guide grooves 7 are distributed in a figure-eight shape, the clamping plates 8 on both sides move along the inclined guide grooves 7. Finally, the seven sets of clamping plates 8 converge towards the center in a ring shape and the injection molded part is flexibly clamped by the silicone layer 9. Among them, such as Figure 4-6As shown, after the clamping plate 8 clamps the injection molded part, tighten the positioning bolt 13 on the mounting plate 12. Its bottom tooth groove engages with the multi-tooth structure at the end of the adjusting rod 6, locking the rotation of the adjusting rod 6 and preventing the movable plate 4 from retracting. The sliding bearing 11 forms a sliding friction pair with the surface of the adjusting rod 6. When the adjusting rod 6 rotates, the sliding bearing 11 reduces the friction loss when the adjusting rod 6 rotates through its own smooth surface, ensuring smooth adjustment. Furthermore, after cooling is complete, first loosen the positioning bolt 13, rotate the adjusting rod 6 counterclockwise, and the threaded transmission causes the adjusting rod 6 to move away from the movable plate 4, which in turn drives the movable plate 4 away from the first guide rod 5. The guide post 10 slides in the opposite direction in the guide groove 7, and the clamping plate 8 unfolds to both sides and releases the injection molding module.

[0020] like Figure 1 As shown, top plates 14 are welded to both sides of the top of the cooling box 1. A second guide rod 15 is provided between the cooling box 1 and the top plate 14, and the second guide rod 15 passes through the top of the side plate 3 and is slidably connected to the side plate 3.

[0021] It should be noted that, in this embodiment, after the injection molding module is fixed, since the top of the side plate 3 is connected to the connection end of the drive component (such as an electric push rod), and a second guide rod 15 is provided between the cooling box 1 and the top plate 14, the drive component is started to drive the side plate 3 to descend along the second guide rod 15, immersing the injection molding module in the cooling medium in the cooling box 1. The filter screen 2 filters impurities to ensure uniform cooling. After cooling is completed, the drive component drives the side plate 3 to rise, and the injection molding module can be taken out from between the clamping plates 8. Optionally, the coolant in the cooling tank 1 can be agitated by a stirring component to increase the cooling effect. The turbulence turbulence of the stirring component is a mature existing technology and will not be described here. In addition, all connecting components in this device are corrosion-resistant components.

[0022] Working principle of this utility model: Refer to the instruction manual appendix Figure 1-6 First, the injection molding module is placed between the clamping plates 8. Then, the position of the clamping plates 8 is adjusted. Since the surface of the adjusting rod 6 away from the movable plate 4 is threaded and is threadedly connected to the inner wall of the side plate 3, when the end of the adjusting rod 6 is rotated clockwise, the front end of the adjusting rod 6 is connected to the movable plate 4. The adjusting rod 6 moves in the side plate 3 through the threaded transmission. The movable plate 4 moves in the direction of the first guide rod 5. When the movable plate 4 moves, the seven sets of guide grooves 7 on it move synchronously. The clamping plates 8 are slidably connected to the guide grooves 7 through the guide post 10. Since the guide grooves 7 are distributed in a figure-eight shape, the clamping plates 8 on both sides move along the inclined guide grooves 7. Finally, the seven sets of clamping plates 8 converge towards the center in an embracing shape and the injection molded part is flexibly clamped by the silicone layer 9. After clamping the injection molded part with clamping plate 8, tighten the positioning bolt 13 on mounting plate 12. Its bottom tooth groove engages with the multi-tooth structure at the end of adjusting rod 6, locking the rotation of adjusting rod 6 and preventing moving plate 4 from retracting. The start-up drive unit drives the side plate 3 to descend along the second guide rod 15, immersing the injection molding module into the cooling medium in the cooling box 1. The filter screen 2 filters impurities to ensure uniform cooling. After cooling is complete, the drive component lifts the side plate 3, loosens the positioning bolt 13, rotates the adjusting rod 6 counterclockwise, and the threaded transmission causes the adjusting rod 6 to move away from the movable plate 4, which in turn moves the movable plate 4 away from the first guide rod 5. The guide post 10 slides in the opposite direction in the guide groove 7, and the clamping plate 8 unfolds to both sides and releases the injection molding module, so that the injection molding module can be taken out from between the clamping plates 8.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
