Problems solved by technology

[0002] It is well known that in the field of extrusion dies for plastic profiles with complex sections, the development of plastic profile sections has higher requirements for structural performance, shape, size, and tolerance. Shape, size, and tolerance requirements ensure that the design, production, and ease of use of the mold can be met. For the unconventional mold sections that continue to appear, new molds must be developed to meet customer requirements, especially in recent years. The profiles replaced by PVC raw materials can realize the production of PVC extrusion dies with complex sections by using this complex section plastic profile extrusion die, so as to meet the diverse requirements of profile assembly, but the existing mold structure can produce The accuracy of plastic products is difficult to guarantee and cannot meet the needs of the market

Embodiment 1

[0013] A long limit screw 3 is set on one side of the front template 1 and the rear template 2 so that the front template 1 and the rear template 2 are combined into one, and the extrusion gap 4 is formed between the front template 1 and the rear template 2, and the middle part of the front template 1 is positioned A gating system 6 is arranged under the middle part of the ring 5 and the positioning ring 5. The gating system 6 is in the shape of a "six", and a pair of molds 8 are symmetrically arranged on both sides of the middle part of the lower edge of the front formwork 1. The glue-out of the mold 8 and the gating system 6 Corresponding to the setting of the mouth, at least one nozzle needle 7 is set on both sides of the lower side of the positioning ring 5, and a core 9 is set corresponding to the mold 8 on both sides of the front of the rear template 2, and a push rod 10 is set inside the core 9, and the outer periphery of the core 9 After the internal thread 11, the fron...

Embodiment 2

[0015] Adjust the long limit screw 3 so that the front template 1 and the rear template 2 are merged together, the extrusion gap 4 between the front template 1 and the rear template 2 is 0.05-0.1mm, the pouring tube is fixed with the front template 1 through the positioning ring 5, The glue in the pouring tube enters the pouring system 6 from the pouring port and enters the cavity between the mold 8 and the core 9 from the glue outlet, and the cooling liquid in the nozzle needle 7 cools the pouring system 6 to keep the pouring system 6 at the setting Within the temperature range, the temperature of the glue when it enters from the gate is 110-120°C, the injection pressure is 90 Pa, and the time is 3 seconds. After entering the cavity, the temperature is 290°C, and the holding pressure is 65 Pa. The time is 2 seconds, the temperature of the second stage is 280°C, the temperature of the third stage is 269°C, and the temperature of the fourth stage is 250°C. The pressure-holding p...

Abstract

Disclosed is an operation method for socket pressing plate. A front mold plate and a rear mold plate are combined together by adjusting a long limiting screw. Glue liquid in a pouring pipe enters a pouring system through a pouring inlet, and enters cavities located between molds and mold cores through glue outlets. Cooling of the pouring system is conducted through cooling liquid in water gap needles so as to make the temperature of the pouring system keep within a set temperature range. The glue liquid enters the cavities through the pouring inlet, and glue in the cavities is solidified to finished products of sealing caps. Extrusion gaps between the front mold plate and the rear mold plate are made to be as same as set spaces by adjusting the long limiting screw. The front mold plate carries the molds to be separated from the products. A power system produces power to make push rods located in the mold cores move forwards. The front ends of the push rods push the finished products of the sealing caps out of the mold cores, and the products are made to fall into the extrusion gaps. The operation method is convenient to conduct and high in practicability. Installation and maintenance are both convenient to conduct. The quality and the precision of the products are effectively ensured. The working efficiency is greatly improved. The production cost is reduced.
