An energy-saving automatic ejection mold

Abstract

The invention discloses an energy-saving automatic push-out mold, which comprises a convex mold substrate and a concave mold substrate, wherein a product cavity bump is arranged at the center position of the front surface of the convex mold substrate; driving rods pointing at a sleeve are respectively arranged on the concave mold substrate; a push plate is connected and arranged between the external tail ends of driven rods; a plurality of demolding rods corresponding to the product cavity bump are arranged on the back surface of the convex mold substrate; the tail ends of the demolding rods are connected with the push plate; a plurality of brackets are arranged on the back surface of the convex mold substrate; a plurality of springs are respectively connected and arranged between the brackets and the push plate; and the push plate drives the demolding rods to move towards the product cavity bump under the pressure action of the springs. Through the manner, according to the energy-saving automatic push-out mold, the push plate restores the normal position under the action of the springs, and drives the demolding rods to push out forwards to rapidly demold formed products. The energy-saving automatic push-out mold is reliable in structure, good in durability and low in energy consumption; and the production cost is reduced.

Description

technical field [0001] The invention relates to the field of mold design for auto parts, in particular to an energy-saving automatic ejection mold. Background technique [0002] Most of the various plastic tools and products we use in our daily life are produced by injection molds. With the development and maturity of engine technology, the fuel consumption of small cars is mainly determined by the weight of the car. Therefore, the lightweight of cars is the direction pursued by various manufacturers. Using plastic products to replace steel used in some parts of cars can greatly reduce the weight of cars , so more and more plastic products are used in the accessories of automobiles, which puts forward more requirements for plastic molds. [0003] In order to release the product quickly, some plastic molds are equipped with hydraulic or pneumatic ejection devices, but the hydraulic or pneumatic ejection devices need to be coordinated with the opening and closing of the mold,...

Problems solved by technology

[0003] In order to release the product quickly, some plastic molds are equipped with hydraulic or pneumatic ejection devices, but the hydraulic or pneumatic ejection devices need to be coordinated with the opening and closing of the mold, and the control system is complex, requiring a lot of adjustment work, and high energy consumption. Poor stability, needs improvement
