Problems solved by technology

[0002] During the molding process of the lock cylinder, because the two sides of the product are completely in the slider, and there are many lock plate grooves and strong tightening force, the product is easy to stick in the slider. The existing core pulling method is shown in figure 1 , when the mold is parted, the inclined pin 1 drives the slider 2 to simultaneously pull the lock plate and the two sides of the lock cylinder, causing the lock plate groove to be strained, and there is a hidden danger of compression molding

Embodiment Construction

[0009] See figure 2 , the present invention comprises a lower mold cavity 2, two sliders 4, 7 arranged in the lower mold cavity 3, the two sliders 4, 7 are sequentially movably connected by shoulder bolts 5, 6, the outer slider 4 of the two sliders Connected with the piston rod 2 of the oil cylinder, the shoulder bolts 5 and 6 are arranged at both ends of the inner slider 7 of the two sliders; the sliders 4 and 7, the shoulder bolts 5 and 6 and the oil cylinder 1 are symmetrically arranged around the workpiece model hole 8 , when the mold is divided, the oil cylinder 1 works, and the cylinder piston rod 2 drives the outer slider 4 to move to realize the core-pulling of the lock plate on the lock groove. After the outer slider 4 moves a certain distance, the inner slider 7 is driven by the shoulder bolts 5 and 6. Movement, the two sides of the lock cylinder together with the lock piece are pulled out, because the oil cylinder drives the lock piece to pull out the core first, a...

Abstract

The invention provides a casting die sliding block core-pulling structure for a lock core. When a core is pulled, a locking plate slot is pulled, and then two sides of the lock core are pulled so as to more easily separate a product, and prevent the locking plate slot from being strained to damage a die. The casting die sliding block core-pulling structure comprises a lower mold cavity and sliding blocks which are arranged in the lower mold cavity, and is characterized in that: the number of the sliding blocks is two, the two sliding blocks are sequentially movably connected through a shouldered tap bolt, and an external sliding block of the sliding blocks is connected with a cylinder piston rod.

Description

technical field [0001] The invention relates to the technical field of die-casting molds, in particular to a core-pulling structure for a slider of a lock cylinder die-casting mold. Background technique [0002] During the molding process of the lock cylinder, because the two sides of the product are completely in the slider, and there are many lock plate grooves and strong tightening force, the product is easy to stick in the slider. The existing core pulling method is shown in figure 1 , When the mold is parted, the oblique pin 1 drives the slider 2 to pull the core on both sides of the locking piece and the lock cylinder at the same time, causing the locking piece groove to be strained, and there is a hidden danger of compression molding. Contents of the invention [0003] In view of the above problems, the present invention provides a core-pulling structure of the lock cylinder die-casting mold slider, which can realize the core-pulling of the lock plate first, and the...
