Embodiment Construction

[0010] The present invention will be further described in detail below through specific implementations:

[0011] The reference signs in the drawings of the specification include: locking block 1, fixed template 2, first sliding block 3, bending pin 4, pusher plate 5, fixed plate 6, backing plate 7, push rod 8, core 9, Die 10, second slider 11.

[0012] The embodiment is basically as attached figure 1 Shown: a side parting injection mold with bending pins, the fixed template is set horizontally, the upper side of the fixed template is provided with a sprue sleeve, and the lower two sides of the fixed template are respectively provided with lower bending pins that are bent outward. There is a cooling water channel on the fixed template.

[0013] A first sliding block, a second sliding block, a concave mold, a pusher plate, a fixing plate, a backing plate, a guide sleeve and a mounting plate are sequentially arranged under the fixed template. The upper part of the concave mold is pr...

Abstract

The invention discloses a side parting injection mold with dog-leg cams. By means of the side parting injection mold, discharging of plastic parts with side pits or side holes is facilitated. The side parting injection mold with the dog-leg cams comprises a horizontal fixed mold plate, a sprue bush is arranged on the upper side of the fixed mold plate, and a female mold capable of moving up and down is arranged below the fixed mold plate; a mold core is arranged on the upper portion of the female mold, a first sliding block and a second sliding block capable of obliquely moving downwards are arranged on the left side and the right side of the upper portion of the female mold respectively, and protrusions are arranged on the inner side of the first sliding block and the inner side of the second sliding block. In mold closing, a cavity is formed among the fixed mold plate, the mold core, the first sliding block, the second sliding block and the female mold, and the cavity is communicated with a runner of the sprue bush; push rods are arranged below the female mold, the dog-leg cams with the lower portions bent outwards are arranged on the two sides of the lower portion of the fixed mold plate respectively, and the first sliding block and the second sliding block are each provided with a through hole which inclines outwards from top to bottom. In mold opening, the dog-leg cams can be inserted into the through holes to force the first sliding block and the second sliding block to obliquely move downwards.

Description

Technical field [0001] The invention relates to a lateral parting injection mould with bent pins. Background technique [0002] The basic structure of the injection mold includes two parts: a movable mold and a fixed mold. The fixed mold part is installed on the fixed plate of the injection machine, and the movable mold part is installed on the moving plate of the injection machine. During injection molding, the fixed mold and the movable mold are closed to form Mold cavity and pouring system, the molten plastic enters the cavity from the nozzle of the injection machine through the pouring system, and solidifies and forms in the cavity. After the mold is opened, the plastic part is ejected by the ejection mechanism. The ejection mechanism of the existing injection mold is usually when the mold is opened, the product is directly ejected from the mold in the mold opening direction through the top plate or the ejector, but this method is not suitable for plastic parts with side hole...
