Description

Technical Field

[0001] The utility model belongs to the technical field of auxiliary equipment for plastic part production, in particular to a cooling mechanism for a plastic part injection mold. Background Art

[0002] An injection mold is a tool for producing plastic products; it is also a tool that gives plastic products a complete structure and precise dimensions. Specifically, it refers to the process of injecting heated and melted plastic into the mold cavity under high pressure by an injection molding machine, and obtaining a molded product after cooling and solidification. Because the plastic parts fall out of the mold after injection molding, the long-term continuous work of the mold itself will cause the temperature of the produced plastic parts to be too high. Existing equipment generally likes to connect the injection mold to a cooling pool, and use the cooling water inside the cooling pool to cool the mold and the product. Although this method can quickly cool the product, it cannot recycle the used cooling water, which wastes a lot of resources and reduces the practicality of the device.

[0003] After searching, for example (authorization announcement number CN214324002U) a cooling mechanism for a plastic injection mold includes a lower mold and a cooling device. The surface of the lower mold is provided with a cooling device, and the cooling device includes two second placement plates. The tops of the two second placement plates are slidably connected to the lower mold, and the two side walls of the second placement plates are slidably connected to the first placement plates. The device solves the problem of long cooling time and slow cooling at room temperature, reduces time waste and improves the working efficiency of the device. However, the device cannot recycle the cooling water after use. After cooling the plastic parts with cooling water, it is often necessary to add a large amount of cooling water frequently, resulting in a waste of resources and reducing the practicality of the device.

[0031] A cooling box 1 is used for cooling products produced by plastic injection molds. A hollow water tank 8 is welded on the top of the cooling box 1. A feed port for adding cooling water is provided on the top of the water tank 8. A fixed cover for sealing is screwed on the feed port, and a booster water pump is installed inside the water tank 8. The delivery section of the booster water pump passes through the top of the cooling box 1 and is connected to a hollow spray plate 10. The spray plate 10 is fixed to the inner top wall of the cooling box 1 by four welded fixing columns, and a plurality of trumpet-shaped spray holes 11 are provided at the bottom of the spray plate 10. The spraying of the coolant is completed through the spray plate 10 and the spray holes 11, and the plastic parts on the conveyor 7 are cooled, thereby accelerating the cooling efficiency.

[0032] A layer plate 12 is provided in the middle of the cooling box 1 for easy separation, and the sides of the layer plate 12 are hollowed out and fixed to the inner wall of the cooling box 1 at intervals. First, the overall structure of the top of the layer plate 12 is high in the middle and low on all sides, similar to a hill-like shape. The side walls of the layer plate 12 are welded to the inner wall of the cooling box 1. In order to facilitate the collection of used coolant into the recycling box, the recycling box is the space formed by the layer plate 12 and the inner bottom wall of the cooling box 1. Hollow holes are provided at the connection between the layer plate 12 and the inner wall of the cooling box 1, so that the coolant after spraying and use is gathered into the recycling box through the set holes, which is convenient for the circulation of the coolant.

[0033] Through grooves 9 are provided at both ends of the cooling box 1, and the two through grooves 9 are fixed with conveyors 7 that penetrate the cooling box 1. The conveyor belt surface of the conveyor 7 is provided with through holes that facilitate the movement of the coolant, and in order not to affect the operation of the conveyor 7, the overall structure of the conveyor 7 is treated with waterproof and anti-corrosion treatment, which not only improves the service life of the device, but also facilitates use;

[0034] A mounting hole 2 is provided on the side wall of the cooling box 1, a fan 3 is embedded in the mounting hole 2, a dust screen is fixed on the outside of the mounting hole 2, and the dust screen can prevent external dust from affecting the plastic parts transported inside the cooling box 1. In combination with the spray holes 11, the cooling efficiency of the plastic parts is further improved through the combined effect of water cooling and air cooling, and the cooled plastic parts can be collected through a collection frame at the other end of the conveyor 7.

[0035] A treatment box 6 for treating used cooling water is fixed at the bottom of the cooling box 1. A through pipe is provided on the top of the treatment box 6. The through pipe passes through the bottom of the cooling box 1 and extends to the inside thereof. Symmetrical knobs 4 are provided on the side walls of the cooling box 1.

The slide plate 14 is welded to the side wall of the sieve plate 13. A sieve 16 for easy cleaning is embedded in the interior of the sieve plate 13. The function of the sieve 16 is to process and recycle the coolant that enters the processing box 6 through the through pipe. A handle 15 is welded at the end of the sieve plate 13. The setting of the handle 15 facilitates the force when the sieve plate 13 is pulled out, and facilitates regular cleaning of the sieve 16 and replacement of the sieve plate 13, so as to always maintain the processing efficiency of the cooling water inside the processing box 6.

The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0039] How it works

[0040] When the operator uses the cooling mechanism for the plastic injection mold, first, he opens the fixed cover to fill the water tank 8 with cooling water, and then closes it, starts the conveyor 7, and conveys the plastic parts processed and produced by the injection molding machine, and starts the embedded fan 3 and the booster water pump arranged in the water tank 8. Under the action of air cooling and water cooling, the plastic parts are cooled, and the used coolant enters the recovery box through the through holes on the surface of the conveyor belt and the pores arranged on the side wall of the layer plate 12;

[0041] Then, turn on the knob 4, and transport the coolant collected in the recovery box to the inside of the treatment box 6 through the connected pipe.
