Embodiment Construction

[0024] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0025] Such as figure 1 , figure 2 As shown, the embodiment of the present invention mainly includes a core 1, a cavity (not shown), a thimble (not shown), a thimble plate 3, a thimble fixing plate 4, a mold foot 2, a lower double plate 5, and an air injection block 6 .

[0026] Specifically, the core 1 is located below the cavity, the thimble is fixed on the thimble fixing plate 4, the thimble plate 3 and the thimble fixing plate 4 are stacked as one, and the mold foot 2 is connected between the core 1 and the lower double plate 5, The thimble plate 3 and the thimble fixing plate 4 are arranged between the core 1 and the lower double plate 5 so as to be movable up and down. Another example is 3- Figure 7 As shown, the air injection block 6 is cylindrical, and an air channel 60 is provided along the length direction inside, an a...

Abstract

The invention provides a mold system provided with an air-assisted forming mechanism. The mold system comprises a mold core, a mold cavity, a thimble, a thimble plate, a thimble fixing plate, mold legs, a fixed core plate and an air injection block, wherein the mold core is positioned below the mold cavity; the thimble is fixed on the thimble fixing plate; the thimble plate and the thimble fixing plate are overlapped into a whole; the mold legs are connected between the mold core and the fixed core plate; the thimble plate and the thimble fixing plate are arranged between the mold core and the fixed core plate in a way of moving upwards and downwards; the air injection block is cylindrical; an air channel is formed inside the air injection block along the length direction; an air inlet communicated with the air channel is formed in the outer end face of the air injection block; a projecting air nozzle for jetting high-pressure air into the mold cavity is arranged on the inner end face of the air injection block; a groove is formed in the side face of the mold core; the air injection block is embedded into the groove; the air nozzle extends into the mold cavity. By adopting the mold system, high-pressure air can be blown into the mold cavity during injection molding by using the air injection block, so that a cavity is formed in a plastic product.

Description

[0001] technical field [0002] The invention relates to the technical field of injection molds, in particular to a mold system with an air-assisted molding mechanism. [0003] Background technique [0004] Plastic products permeate all aspects of production and life, and its importance is self-evident. In the case of meeting the structure and strength requirements, of course, the less raw material consumption, the better, the more it helps to reduce costs, and the more it helps to reduce pollution. Many plastic products have edges with larger cross-sections. If they are formed into a hollow structure, a lot of raw materials can be saved obviously, but there is no such equipment and process at present. [0005] Contents of the invention [0006] The object of the present invention is to provide a mold system with an air-assisted molding mechanism to form a hollow structure in a component with a large cross-section of a plastic product. [0007] In order to solve the ab...
