Secondary side core pulling mechanism

Abstract

The invention provides a secondary side core-pulling mechanism assembled to an injection mold. The secondary side core-pulling mechanism comprises first side pulling slide blocks, first side ejecting and pushing rods, second side pulling slide blocks and second side pulling inclined guide columns, wherein the first side pulling slide blocks are installed on a moving die along the left and right direction of a moving die; the first side ejecting and pushing rods comprise straight rod parts and inclined parts; the top ends of the straight rod parts are installed on a fixed die, and the bottom ends of the straight rod parts are connected with the top ends of the inclined parts, and the bottom ends of the inclined parts extend out of the first side pulling slide blocks; the second side pulling slide blocks are installed on the first side pulling slide blocks along the front and back direction of the moving die; the second side pulling inclined guide columns are inclined along the front and back direction of the moving die, and the bottom ends of the second side pulling inclined guide columns penetrate through the second side pulling slide blocks; when a die is opened, the second side pulling inclined guide columns eject and push the second side pulling slide blocks to perform side pulling for a molded product in a molding cavity, and the first side ejecting and pushing rods eject and push the first side pulling slide blocks so as to perform side pulling for a molded product in a molded cavity, so that the installation is convenient, and the cost is lowered to meet requirements of customers.

Description

technical field [0001] The invention relates to a side core-pulling mechanism, in particular to a secondary-side core-pulling mechanism for sequentially and orderly performing secondary-side core-pulling on molded products. Background technique [0002] With the continuous development of the economy and the continuous progress of society, it provides a wealth of material consumer goods, creating good conditions for improving people's living standards and pursuing personalized life, thereby accelerating the demand for material consumer goods, and plastic products are many One of the material consumer goods. [0003] As we all know, injection molds are commonly used molds for forming plastic products. Various plastic products can be formed through injection molds to meet people's various needs. And due to the various technological requirements of plastic products, it is necessary to open structures such as holes or grooves on the side walls of plastic products. The core mech...

Problems solved by technology

[0004] However, due to the structural problems of plastic products, such as figure 1 As shown, it needs to be in the large position of the side core pulling mechanism (ie figure 1 Put a small row in the direction indicated by the arrow on the right (ie figure 1 The direction indicated by the front and rear arrows in the center is drawn sideways), and because the stroke of the large position is very long, the traditional method is to connect the oil cylinder behind the large position of the side core pulling mechanism. When the movable mold and the fixed mold are opened, use the mold opening Force, so that the inclined guide column fixed on the fixed mold drives the small slider back to the position, and then the oil cylinder drives the large row to move backward, so that the oil cylinders on both sides will far exceed the distance between the green columns of the injection machine distance, which leads to the fact that the injection mold with the existing side core-pulling mechanism cannot be installed on the injection machine
