A special fixture for two-color glue injection of heat-insulating aluminum profiles and two-color glue injection process

Abstract

The invention discloses a special clamp for heat insulation aluminum profile two-color glue injection. The special clamp comprises a clamp body, wherein supporting parts are arranged on the two sides of the clamp body; a groove is formed by encircling of the two supporting parts and the clamp body; holes are formed in the two side surfaces of the groove; clamping pieces are inserted into the supporting parts; an isolating strip is arranged at the middle position of the groove; a convex block is arranged on the clamping piece; a fastening piece is also arranged on the clamping piece. The two-color glue injection technology comprises the following steps: (1) preparation; (2) clamp assembling; (3) adhesive tape sticking; (4) pouring; (5) clamp unloading; (6) inspection, packaging and delivery into a storehouse. The special clamp disclosed by the invention is simple in structure and reasonable in design; two profiles with different colors can be conveniently poured after being clamped, so that the production cost of a two-color profile is greatly reduced; according to the two-color glue injection technology, the technological steps are simple, and special equipment is not needed to be arranged; production of a two-color glue injection profile can be completed by only using some clamps and the existing single-color glue injection equipment; the operation is convenient, the cost-performance is high, and popularization and application are facilitated.

Description

technical field [0001] The invention belongs to the technical field of aluminum alloy profile production technology, and in particular relates to a special fixture for two-color glue injection of heat-insulating aluminum profiles and a two-color glue injection process. Background technique [0002] With the rapid development of aluminum alloy insulated doors and windows, double-color insulated aluminum alloy windows are gradually favored by customers because of their beautiful appearance and the ability to realize indoor and outdoor colors according to different needs of users. At present, the production of two-color heat-insulating aluminum alloy window profiles mainly adopts the threading process, which has strict requirements on the structure of the profile, resulting in a larger proportion of the profile and high cost, and the profile prepared by the threading process is in use.

Problems solved by technology

At present, the production of two-color heat-insulating aluminum alloy window profiles mainly adopts the threading process, which has strict requirements on the structure of the profile, resulting in a larger proportion of the profile and high cost, and the profile prepared by the threading process is in use. It is easy to imagine water seepage in the middle, and this problem has been plagued by the development of double-color heat-insulated aluminum alloy windows. There are the following defects: 1. The equipment structure is complex, expensive, and difficult to popularize and apply; 2. Each profile product must be equipped with a profiling fixture, and the mold cost is high; 3. The operation is cumbersome and the work efficiency is low, far inferior to the threading process ; 4. Two-color glue injection profiles, the market share is not high

Therefore, the use of two-color glue injection profile production equipment is not cost-effective, and it is difficult for profile manufacturers to accept and cannot be promoted.
