Examples
Referring to fig. 2 to 11, the present embodiment provides a core block locking mechanism, which includes a block housing 200 for fixing the core block 100, a wedge block 300 engaged with the block housing 200, and a driving member 400 for driving the wedge block 300 to move; the sliding block holder 200 is provided with a first sliding surface 210 and a second sliding surface 220, and the wedge block 300 is provided with a first guide surface 310 matched with the first sliding surface 210 and a second guide surface 320 matched with the second sliding surface 220; the slider holder 200 is configured to be moved by the driving member 400 to switch between a locked state in which the first sliding surface 210 abuts against the first guide surface 310 in a horizontal position and a sliding state in which the second sliding surface 220 slides along the second guide surface 320, and a sliding state in which the slider holder 200 is switched between the locked state and the sliding state.
It should be noted that, in this embodiment, when the slider seat 200 is in the locked state, the first sliding surface 210 abuts against the first guiding surface 310 at the horizontal position, so as to prevent the injection pressure in the injection molding process from generating a side pressure on the wedge block 300, thereby locking the core-pulling slider 100, and solving the problem of poor product caused by the backward movement of the core-pulling slider 100 in the injection molding process. It is easily understood that, in the prior art, when the two inclined surfaces abut against each other in the locking state, the wedge block 300 retreats under the action of the side thrust force, which causes the core back slider 100 to move away from the mold clamping surfaces (the mold clamping surfaces of the movable mold and the fixed mold), resulting in product defects. In this embodiment, the two horizontal surfaces of the slider holder 200 abut against each other when in the locked state, and the slider holder 200 and the wedge block 300 are limited in the vertical direction, that is, the first sliding surface 210 of the slider holder 200 abuts against the first guiding surface 310 of the wedge block 300, so as to ensure that the core back slider 100 does not move in the direction away from the clamping surface.
In addition to the above embodiments, in an alternative embodiment of the present invention, the first sliding surface 210 and the first guiding surface 310 are both horizontally disposed, and the second sliding surface 220 and the second guiding surface 320 are disposed as inclined surfaces. For example, when the slider holder 200 is in the locked state, the driving member 400 abuts against the wedge block 300, and even if the pressure of the injection molding causes the wedge block 300 to move backward, the first sliding surface 210 can only move horizontally along the first guiding surface 310, so that the position of the core back slider 100 is kept unchanged; when the slider holder 200 is in a sliding state, the wedge block 300 moves to the outside of the mold under the action of the driving element 400, so that the second sliding surface 220 slides along the second guiding surface 320, and the core-pulling slider 100 is driven to move in a direction away from the mold clamping surface, thereby realizing the demolding process.
Specifically, the slider holder 200 is provided with a sliding groove 230, guide portions 240 for clamping the wedge block 300 are protruded at both sides of the sliding groove 230, and the top surface of the sliding groove 230 is provided with a first sliding surface 210 and a second sliding surface 220. So that the slider holder 200 and the wedge block 300 move in a desired direction.
Further, the wedge block 300 is provided with guide grooves 330 on both sides thereof, the extending direction of the guide grooves 330 is the same as the inclined direction of the second guide surface 320, the guide portions 240 of the slider holder 200 are accommodated in the guide grooves 330 to move, and the guide portions 240 can be fitted with the bosses 340 extending outward on both sides of the second guide surface 320, so that the slider holder 200 slides along the second guide surface 320.
In another embodiment, the guiding portion 240 has a first inclined surface 241 and a second inclined surface 242 arranged at an angle, the first inclined surface 241 is configured to cooperate with the boss 340, and the first inclined surface 241 moves along the boss 340 in the sliding state.
Based on the above embodiments, in an alternative embodiment of the present invention, the driving member 400 is a hydraulic cylinder. In the prior art, to realize locking of the core-pulling slider 100, a self-locking hydraulic oil cylinder can be adopted, but the cost is high, and in the embodiment, locking can be realized through a common hydraulic oil cylinder, so that the cost of a mold can be saved.
Preferably, wedge block 300 is connected to the hydraulic ram by a locking member 500, the locking member 500 being stepped shaft shaped.
Further, the wedge block 300 is provided with a T-shaped groove 350 at the opposite side of the second guide surface 320, one end of the locking member 500 is engaged with the T-shaped groove 350 in a concave-convex manner, and the other end is fixedly connected with a piston rod of the hydraulic cylinder through a screw.
In a preferred embodiment, the slider holder 200 is provided with a water flow passage that sealingly interfaces with the core slider 100 to cool the core slider 100. For example, a water inlet channel 600 and a water outlet channel 700 are respectively disposed on two sides of the slider seat 200, in this embodiment, the core back slider 100 is in a long strip shape, a water path in the core back slider 100 is arranged along a length direction thereof, external water is injected into the water path in the core back slider 100 through the water inlet channel 600, and is finally discharged from the water outlet channel 700, so as to cool the core back slider 100, where it should be noted that the water inlet channel 600 and the water outlet channel 700 are both arranged along a moving direction of the wedge block 300.
Above only the utility model discloses an it is preferred embodiment, the utility model discloses a scope of protection not only limits in above-mentioned embodiment, and the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection.
