Description

Large-pitched roof side buckle demolding mechanism of injection mold

Technical Field

The utility model relates to an injection mold especially relates to injection mold pushes up top surface side buckle demoulding mechanism to one side greatly.

Background

When adopting injection mold production plastic products, if limit structure such as protruding muscle of side inner wall of plastic products, barb, buckle, traditional mode sets up oblique top at the lateral wall of movable mould board usually, upwards removes together with the product by the oblique top when upwards ejecting with plastic products, and moves the limit structure who deviates from the product gradually to the inboard when ejecting upward moving to the top to one side, at last with the ejecting drawing of patterns of product. However, when the side inner wall of the plastic product has a limit structure, and there is also a limit structure on the side wall, and the limit structure is in the boundary position between the large inclined top and the core, the existing mode is usually that a guide block is arranged in the movable template, the side wall of the guide block is provided with a guide rail, a side ejector rod is arranged in the large inclined top, one end of the side ejector rod is in guide fit with the guide rail, the other end of the side ejector rod is in guide fit with the limit structure on the side wall of the product, when the large inclined top is ejected upwards, the large inclined top drives the side ejector rod and the product to move upwards together, the large inclined top gradually releases the limit structure on the side inner wall of the product through inward movement, and meanwhile, the side ejector rod releases the limit structure on the side wall of the product through the guide rail fit with the guide block, but the structure has the disadvantages that: the guide rail highly need be greater than the ejecting stroke of big oblique top, just can avoid deviating from the guide rail when the side ejector pin rebound, consequently the guide block has taken very big space in the movable mould board, if need be covered with various ejecting structures and waterway structure in the movable mould board, then do not have enough space to set up the guide block, its commonality is relatively poor to the structure is complicated, and it is troublesome to make, has improved the manufacturing cost of mould.

Disclosure of Invention

The utility model aims at overcoming the shortcoming that prior art exists, providing a small, it is few to occupy the mould inner space, simple structure, it is convenient to make, reduces mould manufacturing cost, guarantees the big oblique top surface side buckle demoulding mechanism of injection mold of the smooth drawing of patterns of plastic products.

The utility model discloses big oblique top surface side buckle demoulding mechanism of injection mold's technical scheme is: including compound board down, set up the mould foot on the compound board down, set up thimble board, thimble and oblique footstock down on the compound board between the mould foot, set up oblique ejector pin on the footstock, set up fixed die plate and big oblique top on the mould foot, oblique ejector pin cooperatees with big oblique top, sets up the core on fixed die plate and big oblique top, the upper end system of big oblique top have oblique spout, set up oblique draw runner in the spout, one end lateral wall system of oblique draw runner has protruding muscle, system has the guide sliding rib above the another of oblique draw runner, system has the guide sliding groove in the bottom of core, guide sliding groove and guide sliding rib cooperate.

The utility model discloses a side buckle demoulding mechanism of a large inclined top surface of an injection mould, when a plastic product is injection-molded, an upper ejector plate and a lower ejector plate are driven by power to move upwards together, the upper ejector plate and the lower ejector plate drive an ejector pin and an inclined ejector seat to move upwards, the ejector pin drives a core to move upwards, the inclined ejector seat drives the large inclined top to move upwards through an inclined ejector rod 7, the core and the large inclined top push the plastic product upwards together, when the large inclined top moves upwards, the core gradually moves inwards in an inclined way, so that the large inclined top can be separated from a limit structure on the inner wall of the side surface of the plastic product (the limit structures such as a convex rib, a barb, a buckle and the like which can be separated from the inner wall of the side surface of the plastic product), and when the large inclined top moves inwards in the inclined direction, an inclined slide bar on the large inclined top is matched with a guide chute at the bottom of the core through the guide slide bar, the inclined slide bar is reversely pushed outwards relative to the large inclined top, so that the convex rib of the inclined slide bar is separated from the side wall of the side surface of the plastic product gradually, and finally ejecting the plastic product out of the mold. This scheme injection mold pushes up top surface side buckle demoulding mechanism greatly to one side, through set up oblique draw runner on pushing up greatly to one side, the system has the guide slide muscle on the draw runner to one side, there is the guide slide groove bottom system of core, utilize the guide slide groove and guide slide muscle cooperation to drive the limit structure on the draw runner removal deviates from the plastics product side lateral wall, its small in size, occupation space is few, thereby more be favorable to arranging in some inner structure compact's moulds, the commonality is good, and simple structure, it is convenient to make, the manufacturing cost of mould has been reduced.

The utility model discloses injection mold pushes up top surface side buckle demoulding mechanism to one side greatly, the lateral wall system of draw runner has spacing, and it has the mounting groove to push up to one side greatly to make, sets up the layering in the mounting groove, and the layering is fixed mutually through fastener and big top to one side, and the layering cooperatees with spacing. The pressing strip is arranged, so that the sliding of the oblique sliding strip is limited and guided, and the action of the oblique sliding strip is more stable, smooth and reliable.

The front end face of the oblique sliding strip is an inclined plane or an arc surface. When the die is assembled, the front end surface of the oblique sliding strip is an inclined surface or an arc surface and is matched with the inner wall of the fixed die side structure, so that the die collision is avoided.
