Description

New Plastic Parts Side Core Pulling Injection Mold

technical field

The utility model relates to a novel side core-pulling injection mold for plastic parts.

Background technique

Mold, various molds and tools used in industrial production for injection molding, blow molding, extrusion, die-casting or forging forming, smelting, stamping and other methods to obtain the required products. In short, a mold is a tool used to shape an object. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the article through the change of the physical state of the formed material. When the injection molding side wall has plastic parts such as holes, pits, and bosses, the parts formed on the mold must be made into laterally movable parts, called movable cores. The active core must be pulled out before the plastic part is demoulded, otherwise it will not be possible to demould. The entire mechanism that drives the movable core to move sideways is called the lateral parting and core-pulling mechanism, referred to as the side core-pulling mechanism. The traditional side core-pulling mold has complex structure, cumbersome operation and poor core-pulling effect.

Further, the ejection assembly includes a push rod for pushing out the push plate and a push rod for pushing out the plastic part.

Further, the guide assembly includes a guide post installed on the support plate, and a guide sleeve sleeved on the guide post is provided on the fixed plate.

Further, the pusher plate is provided with guide grooves for sliding sliding of side core sliders.

Further, the fixed plate is equipped with a wedging block that presses against the core slide block on the side.

Further, the sprue sleeve is screwed to the center of the fixed template.

The beneficial effects of the utility model are: the utility model has the advantages of simple structure, reasonable design, and convenient operation. Through the mutual cooperation of the inclined guide column and the side core slider, the effect of core pulling and pushing out is good, the product quality is improved, and the production speed is accelerated.

detailed description

The utility model is described further in conjunction with accompanying drawing now. These drawings are simplified schematic diagrams only to illustrate the basic structure of the utility model in a schematic way, so they only show the configurations related to the utility model.

Referring to Fig. 1, this embodiment discloses a new type of side core-pulling injection mold for plastic parts, including a movable mold assembly and a fixed mold assembly, the movable mold assembly includes a support plate 8, and a movable template 5 is installed on the support plate 8, A pusher plate 4 is installed on the movable template 5, a punch 7 is provided at the center of the support plate 8, the pusher plate 4 and the movable template 5 are set on the punch 7, and a side core slider 2 is arranged above the pusher plate 4 , the support plate 8 is fixedly installed with an inclined guide column 3, and the side core slider 2 is provided with an inclined guide hole corresponding to the inclined guide column 3; the fixed mold assembly includes a fixed template 11, and the center of the fixed template 11 is provided with a Muzzle 12; Push-out assembly and guide assembly are installed on the support plate 8, and the angle between the axis of the inclined guide post 3 and the horizontal plane is 108 °.

The push-out assembly includes a push rod 6 for pushing out the push piece plate 4 and a push rod 10 for pushing out the plastic part; the guide assembly includes a guide post 9 installed on the support plate 8, and the fixed template 11 is provided with a guide that is sleeved outside the guide post 9. Cover 13; the pusher plate 4 is provided with a guide chute for sliding of the side core slider 2; the fixed template 11 is equipped with a wedging block 1 for pressing the side core slider 2; the sprue sleeve 12 is threaded on the fixed Template 11 Center.

The side core slide block 2 is installed in the guide chute of the push piece plate 4, and is locked by the wedge block arranged on the fixed template when the mold is closed. When the mold is opened, the side core slider 2 and the inclined guide column 3 move down together with the movable mold part and separate from the fixed mold.
