Precision mold for plastic product molding

Abstract

The invention relates to the technical field of plastic products, and particularly relates to a precision mold for plastic product molding. The precision mold for plastic product molding accelerates a cooling time for a plastic product, increases the molding efficiency, reduces the production cost and improves the practicability of the device by adding a cooling mechanism. The precision mold for plastic product molding comprises a base, four groups of guide columns, a top plate, a sliding plate, a hydraulic cylinder, a lower fixed mold and an upper movable mold, wherein the bottom ends of the four groups of guide columns are connected with the top end of the base, the top ends of the four groups of guide columns are connected with the bottom end of the top plate, and the sliding plate is slidably connected with the outer walls of the four groups of guide columns separately. The precision mold for plastic product molding further comprises two groups of supporting seats, two groups of first telescopic cylinders, two groups of cooling plates, a first connecting hose, a second connecting hose, a water storage tank, a water injection pipe, a plunger pump, a conveying pipe, a water outlet pipe and a water return pipe, wherein the bottom ends of the two groups of supporting seats are connected with the top end of the base, and the side walls of the two groups of first telescopic cylinders are connected with the opposite side walls of the two groups of supporting seats separately; and the output ends of the two groups of first telescopic cylinders are connected with the side walls of the two groups of cooling plates separately.

[0002] The precision mold for plastic product molding is an auxiliary device for injection molding of plastic products, which has been widely used in the field of plastic products; the existing precision mold for plastic product molding includes a base, four sets of guide posts, and a top , slide plate, hydraulic cylinder, lower fixed mold and upper movable mold, the bottom ends of the four sets of guide pillars are connected with the top of the base, the tops of the four sets of guide pillars are connected with the bottom of the top plate, and the slide plates are connected with the bottom ends of the four sets of guide pillars. The outer wall can be slidably connected, the bottom of the hydraulic cylinder is connected with the top of the top plate, the output end of the hydraulic cylinder extends to the underside of the top plate and is connected with the top of the slide plate, the bottom of the lower fixed mold is connected with the top of the base, and the upper movable mold The top end is connected with the bottom end of the slide plate, and after the lower fixed mold and the upper movable mold are closed, a cavity conforming to the shape of the finished product is set inside; when the existing precision mold for plastic product molding is used, the hydraulic cylinder is first opened, and the hydraulic cylinder The output end is displayed, and pushes the slide plate to move down along the four sets of guide pillars, so that the bottom end of the upper movable mold and the top end of the lower fixed mold are closed, and then the molten plastic is injected into the cavity of the lower fixed mold and the upper movable mold After the plastic is cooled, shrink the output end of the hydraulic cylinder to separate the lower fixed mold from the upper movable mold, and then take out the molded product; it is found in the use of the existing precision molds for plastic product molding that it takes a lot of time to wait for cooling. Reduced production efficiency, increased work production costs, resulting in poor practicability of the device
