Anti-displacement connection structure for plastic mold used for aluminum-wood door and window production

Abstract

The invention relates to the technical field of plastic molds, in particular to an anti-displacement connection structure for a plastic mold used for aluminum-wood door and window production. The anti-displacement connection structure comprises a plastic mold body. The plastic mold body comprises an upper left mold block, a lower left mold block, an upper right mold block and a lower right mold block. Elastic pressing blocks used for controlling elastic limiting blocks to move downwards are arranged on the two sides of a connection supporting plate respectively, and therefore the elastic limiting blocks and limiting grooves can not be thoroughly separated until the elastic pressing blocks on the two sides are pressed down at the same time, misoperation is prevented, safety and stability between connection pieces are improved, and the product quality is improved.

Description

technical field [0001] The invention relates to the technical field of plastic molds, in particular to an anti-displacement connection mechanism for plastic molds produced by aluminum-wood doors and windows. Background technique [0002] At present, most of the aluminum-wood door and window profiles on the market are solid wood frames and aluminum alloy frames made of aluminum alloy. However, at the connection between the aluminum alloy frame and the solid wood frame, due to the difference in thermal expansion coefficients between the aluminum alloy and the solid wood, the solid wood frame is prone to deformation. However, the connection end of the traditional plastic mold used to produce aluminum-wood doors and windows has simple structure, single function, poor displacement resistance, and is prone to displacement. However, the traditional connection mechanism with a limit device is prone to misoperation during the production process, resulting in displacement of the conne...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is: in order to solve the problems existing in the above-mentioned background technology, an improved anti-displacement connection mechanism for plastic molds used in the production of aluminum-wood doors and windows is provided to solve the problem of connecting plastic molds commonly used in the production of aluminum-wood doors and windows. The structure of the end is simple, the function is single, the anti-displacement performance is poor, and it is prone to displacement. However, the traditional connection mechanism with a limit device is easy to misuse during the production process and cause the displacement of the connection end, resulting in the problem of reduced airtightness and connection firmness.
