Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings.

[0016] The present invention produces PC extruded product and uses stereotypes box such as figure 1 As shown, the box body 1 is fixed on the frame 10, and the moving device 9 is fixed on the frame 10, which can be adjusted up, down, left, right, front and back. The nozzle 13 is evenly fixed on the spray pipe 12, and the spray pipe 12 is evenly distributed around the box to achieve 360-degree full coverage cooling. The water separator A14 is fixed on the box 1, and is connected with each channel The cooling water ring is connected, and a valve is installed on each road, which can realize 11 point-to-point adjustments of each cooling water ring. The cooling water ring 11 is fixed on the box body 1, and several small holes are evenly distributed on the circumference of the cooling water removal ring 11, and are connected with the water separator B3 through a steel wire ...

Abstract

The invention discloses a sizing box for producing PC (poly carbonate) extrusion molding products. Cooling water rings are produced and fixed on a box body; a plurality of small holes are uniformly distributed in the peripheries of the cooling water rings, and are connected with a water distributor B through a steel wire flexible pipe; the cooling water rings can move back and forth in the box body, so that the cooling effect is controlled; the water distributor B is provided with a ball valve capable of controlling water feed quantity of the two cooling water rings; a liquidometer is fixed on the box body, and can control the liquid level of the box body up and down, so that immersion cooling or spraying cooling can be selected when different structural products are produced; a heater and a cooler are fixed in a water tank; the heater can heat up cooling water in the water tank, so that the best cooling effect is achieved, and meanwhile thermal stress of the products is removed; and the cooler plays the role of controlling the water temperature to be within the set range so as to achieve the balanced effect.

Description

technical field [0001] This patent belongs to the field of extrusion auxiliary machinery, in particular to a cooling and calibrating box for molding PC extruded plastic products. Background technique [0002] At present, there are the following disadvantages in the production of cooling and shaping tables for PC profiles: 1. The cooling box of the shaping table is immersion cooling, and the PC profiles are directly immersed in the cooling box. The surface cooling speed is too fast, and the internal cooling is slow, which can easily cause shrinkage deformation; 2. The cooling is immersion type, and the water circulation cannot be carried out as soon as possible, and the first-in-first-out is achieved, resulting in low cooling efficiency; 3. Since the cooling box adopts an integrated structure, it is impossible to adjust the cooling capacity of the cooling box in sections to achieve graded cooling of the profiles , It is easy to cause deformation of the profile; 4. Since the c...
