Description

Technical Field

[0001] The utility model relates to the field of cooling and shaping equipment, and particularly to a cooling and shaping device for plastic-steel profiles. Background Art

[0002] Plastic-steel profiles are PVC profiles used for making doors and windows. Since the doors and windows made of pure PVC profiles are not strong enough, steel is usually added into the cavity to enhance the firmness of the doors and windows. Therefore, the plastic doors and windows made by adding steel inside the profiles are usually called plastic-steel doors and windows. At present, plastic-steel profiles are produced by the method of hot extrusion molding. After molding, the temperature of the plastic-steel profiles is relatively high and needs to be cooled and shaped in time.

[0003] The Chinese utility model patent with the publication number of CN216466092U discloses an adjusting device for a cooling water tank for profile molding. The adjusting device for the cooling water tank includes a cooling water tank. An irregular feeding port is formed at one end of the cooling water tank, and an irregular discharging port is formed at the other end. The irregular feeding port and the irregular discharging port are arranged flush. Water-blocking members are respectively arranged on the irregular feeding port and the irregular discharging port. A feeding port is formed in the middle of the water-blocking member, and a water-blocking inner ring is installed inside the feeding port. The plastic-steel profile passes through the irregular feeding port and the irregular discharging port in sequence. However, this cooling water tank is filled with cooling water for submerging the profile. The volume of the cooling water tank is relatively large, and the mixing effect of the added cooling water and the original cooling water in the cooling water tank is not good, resulting in uneven and unstable temperature of the cooling water in the cooling water tank, and further resulting in poor cooling effect of the profile.

[0004] Therefore, a new technical solution is needed in this field to solve the above problems. Summary of the Invention

The cooling and shaping device includes: a cooling mold adapted to be connected to an extrusion mold; a cooling water tank having a feeding end close to the cooling mold and a discharging end far from the cooling mold; a plurality of partition plates are arranged at intervals and detachably in the cooling water tank, and the partition plates are configured to divide the cooling water tank into a plurality of cooling chambers at intervals; a drain port communicating with the cooling chamber is formed at the bottom of the cooling water tank, and each cooling chamber corresponds to at least one drain port; a water inlet mechanism includes a water inlet pipe and a water pump connecting the water inlet pipe and the drain port; a water inlet hole is formed in the water inlet pipe, and each cooling chamber corresponds to at least one water inlet hole.

A partition is arranged in the cooling water tank, and the partition divides the cooling water tank into multiple cooling chambers. Each cooling chamber corresponds to at least one drain port and at least one water inlet hole. Cooling water is conveyed to the cooling chamber through the water inlet hole and then discharged from the cooling chamber through the drain hole. The relative volume of each cooling chamber is small, which can ensure the timely circulation of the cooling water in the cooling chamber and ensure the uniformity and stability of the temperature of the cooling water. Through the above settings, the cooling and shaping device for a plastic-steel profile of the present utility model forms cooling chambers with relatively small volumes by arranging partitions, and each cooling chamber corresponds to at least one drain port and one water inlet, so that it is relatively convenient to input and discharge cooling water, realize the timely circulation of the cooling water, and ensure the uniformity and stability of the temperature of the cooling water.

[0007] Further, a limiting member for the profile to pass through is detachably arranged on the partition; a limiting rod is slidably arranged on the partition, and a limiting hole matching the limiting rod is opened on the limiting member.
