Embodiment Construction
[0007] See figure 1 , which includes a front mold core 1 and a rear mold core 2. Between the front mold core 1 and the rear mold core 2 is a cavity 3, the cavity 3 is close to the floating insert 4, and the floating insert 4 is located between the front mold core 1 and the rear core 2. In the floating insert installation cavity between the mold cores 2, the wave bead screw 5 is located in the installation groove of the rear mold core 2, and the upper wave bead 6 of the wave bead screw 5 is mounted on the lower end surface of the floating insert 4, and the floating insert The bottom of 4 is fastened and connected with stroke screw 7, leaving a distance L between the upper end surface of bolt 8 at the lower end of screw 7 and the lower end surface of rear mold core 2, and the thimble 9 penetrates rear mold core 2 and is top-loaded in cavity 3.

The invention provides a floating insert mold structure. A mold can be subjected to demolding successfully, the surface of a product is not damaged, and the quality of the product is guaranteed. The structure comprises a front mold core and a rear mold core, wherein a cavity exists between the front mold core and the rear mold core. The structure is characterized in that the cavity is attached to a floating insert closely, the floating insert is located in a floating insert installation cavity between the front mold core and the rear mold core, a ball screw is located in an installation groove of the rear mold core, an upper ball top of the ball screw is installed on the lower end face of the floating insert, the lower portion of the floating insert is connected with a stroke screw fixedly, a distance L is reserved between the upper end face of the screw at the lower end of a forming screw and the lower end face of the rear mold core, and a supporting pin penetrates through the rear mold core and is installed in the cavity in a supporting mode.
Description
technical field [0001] The invention relates to the technical field of mold structures, in particular to a floating insert mold structure. Background technique [0002] When the product material is relatively hard, such as POM NYLON, etc., it has an undercut of 0.2-0.3MM, and the existing mold structure is difficult to release the mold smoothly. Forced release will cause damage to the product surface and affect the quality of the product. Contents of the invention [0003] In view of the above problems, the present invention provides a floating insert mold structure, which enables the mold to be demoulded smoothly without damaging the surface of the product and ensures the quality of the product. [0004] The technical scheme of the floating insert mold structure is as follows: it includes a front mold core and a rear mold core, and the cavity between the front mold core and the rear mold core is characterized in that: the cavity is close to the floating insert , the ...
