Abstract
The utility model provides an exhaust device of injection mold, includes the back template of meeting with preceding template, be provided with the exhaust guide slot between preceding template and the back template, the depth capacity of exhaust guide slot is 0.1~0.3mm. The exhaust is provided with in the guide slot and is the protrusion wavy or cockscomb structure, should set up at protruding direction interval along the exhaust guide slot. The slope of exhaust guide slot sets up up, and the inclination scope of exhaust guide slot is 0.5~2 degree. The utility model provides a preceding template and back are provided with the exhaust guide slot between the template, are provided with in the exhaust guide slot to be the protruding of wavy or cockscomb structure, should set up at protruding orientation interval along the exhaust guide slot, so, increased the degree of depth of exhaust guide slot to, be provided with the liquid that blocks the usefulness of moulding plastics that swells that is wavy or cockscomb structure in the guide slot in the exhaust, prevent that this liquid from discharging along the exhaust guide slot outwards, improved the security performance. The utility model has the characteristics of simple structure is reasonable, the exhaust is effectual.
Description
Technical field
This utility model relates to the exhaust apparatus of a kind of injection mold.
Background technology
Existing mold structure, as shown in accompanying drawing 1-accompanying drawing 2, is provided with air discharge duct 3 between front template 1 and rear pattern plate 2, owing to the degree of depth h ratio of air discharge duct 3 is shallower, is only 0.05mm, and in actual production process, this air discharge duct 3 is easy to blocked, does not have the effect of aerofluxus.
Utility model content
The purpose of this utility model aims to provide the exhaust apparatus of the injection mold of a kind of simple and reasonable, good exhaust effect, to overcome weak point of the prior art.
By the exhaust apparatus of a kind of injection mold that this purpose designs, including the rear pattern plate connected with front template, its architectural feature is to be provided with discharge guiding groove between described front template and rear pattern plate, and the depth capacity of described discharge guiding groove is 0.1～0.3mm.
Further, being provided with in wavy or jagged projection in described discharge guiding groove, this projection is arranged along the interval, direction of discharge guiding groove.
Further, described discharge guiding groove tilts to arrange upward, and the range of tilt angles of discharge guiding groove is 0.5～2 degree.
Further, being additionally provided with horizontal chamber between described front template and rear pattern plate, described horizontal chamber is connected with discharge guiding groove.
Further, described horizontal chamber is arranged on front template and/or rear pattern plate.
Further, described discharge guiding groove is arranged on rear pattern plate.
Being provided with discharge guiding groove between front template and rear pattern plate in this utility model, the depth capacity of described discharge guiding groove is 0.1～0.3mm；It is provided with in wavy or jagged projection in discharge guiding groove, this projection is arranged along the interval, direction of discharge guiding groove, then, add the degree of depth of discharge guiding groove, and, it is provided with in discharge guiding groove in wavy or jagged projection to stop injection molding liquid, it is prevented that this liquid runs down discharge guiding groove is discharged outwardly, improves security performance.
Being additionally provided with horizontal chamber between front template and rear pattern plate in this utility model, described horizontal chamber is connected with discharge guiding groove, and horizontal chamber is arranged on front template and/or rear pattern plate；When injection molding liquid enters discharge guiding groove, horizontal chamber can hold a small amount of injection molding liquid, prevent that discharge guiding groove is blocked is beneficial to aerofluxus, and, enter the injection molding liquid in the indoor injection molding liquid of transverse chambers and entrance discharge guiding groove when cooling, condense in together, also allow for the removing of the remaining injection molding waste after die sinking.
In sum, this utility model has feature simple and reasonable, good exhaust effect.
