Abstract
The utility model discloses an inversion type injection mold structure which comprises a fixed die plate and a movable die plate, wherein the fixed die plate is provided with a fixed die insert; corresponding to the fixed die insert, the movable die plate is provided with a movable die insert; an ejector retainer plate and an ejector base plate are arranged above the fixed die plate; the ejector retainer plate is mounted on the lower surface of the ejector base plate through a bolt; an ejector pin is clamped between the ejector retainer plate and the ejector base plate; ejection oil cylinders are respectively arranged on the left end side and the right end side of the fixed die plate; the ejection oil cylinders are respectively fixed to the fixed die plate; and the outward extending ends of piston rods of the ejection oil cylinders are respectively connected with the ejector retainer plate or the ejector base plate. When dies are assembled, the piston rods of the ejection oil cylinders upwards push the ejector retainer plate or the ejector base plate, the ejector pin upwards moves and withdraws from the molding surface of the fixed die insert; and when dies are opened, after the movable die plate and the fixed die plate are relatively opened, the piston rods of the ejection oil cylinders downwards pull the ejector retainer plate or the ejector base plate, and the ejection pin downwards moves and a plastic product is withdrawn from the position of the fixed die insert. Thus, the inversion type injection mold structure has the advantages of compact structure and small volume.
Description
Technical field
The utility model relates to injection mold technical field, relates in particular to a kind of inversion type injection mold structure.
Background technology
The push piece assembly of existing injection mold is generally positioned at moving platen side, and face needle plate, end needle plate are between two cushion blocks; In actual production process, there is the defect that volume is larger in existing injection mold.
Utility model content
The purpose of this utility model is to provide a kind of inversion type injection mold structure for the deficiencies in the prior art, the little and compact conformation of this inversion type injection mold structure volume.
For achieving the above object, the utility model is achieved through the following technical solutions.
A kind of inversion type injection mold structure, include the solid plate of arranged stacked and be positioned at the moving platen of solid plate below, solid plate is fitted with cover half mold insert, the corresponding cover half mold insert of moving platen is fitted with dynamic model mold insert, on solid plate, can be equiped with relatively actively face needle plate and end needle plate, face needle plate is screwed on the lower surface of end needle plate, between face needle plate and end needle plate, is installed with thimble; The left end side of solid plate and right-hand member side are equiped with respectively an ejection cylinder, every go out the cylinder body of oil cylinder be individually fixed in solid plate, every go out the piston rod epitaxial end portion of oil cylinder be connected with face needle plate or end needle plate respectively.
Wherein, the corresponding each described ejection cylinder of described solid plate is equiped with respectively fixed block, every go out the cylinder body of oil cylinder be individually fixed in the fixed block of corresponding side.
The beneficial effects of the utility model are: a kind of inversion type injection mold structure described in the utility model, it includes the solid plate of arranged stacked and is positioned at the moving platen of solid plate below, solid plate is fitted with cover half mold insert, the corresponding cover half mold insert of moving platen is fitted with dynamic model mold insert, on solid plate, can be equiped with relatively actively face needle plate and end needle plate, face needle plate is screwed on the lower surface of end needle plate, between face needle plate and end needle plate, is installed with thimble; The left end side of solid plate and right-hand member side are equiped with respectively an ejection cylinder, every go out the cylinder body of oil cylinder be individually fixed in solid plate, every go out the piston rod epitaxial end portion of oil cylinder be connected with face needle plate or end needle plate respectively.When matched moulds, the piston rod of ejection cylinder is pushing tow face needle plate or end needle plate upward, and thimble moves and recess the forming surface of cover half mold insert upward; When die sinking, until moving platen is relative with solid plate open after, the piston rod of ejection cylinder pulls face needle plate or end needle plate down, thimble moves down and plasthetics is exited from cover half mold insert position.Comprehensive above-mentioned situation is known, the utlity model has the advantage that compact conformation and volume are little.
Accompanying drawing explanation
Utilize accompanying drawing to be further detailed the utility model below, but the embodiment in accompanying drawing does not form any restriction of the present utility model.
Fig. 1 is structural representation of the present utility model.
In Fig. 1, include:
The specific embodiment
Below in conjunction with concrete embodiment, the utility model is described.
As shown in Figure 1, a kind of inversion type injection mold structure, include the solid plate 1 of arranged stacked and be positioned at the moving platen 2 of solid plate 1 below, solid plate 1 is fitted with cover half mold insert 3, the corresponding cover half mold insert 3 of moving platen 2 is fitted with dynamic model mold insert 4, on solid plate 1, can be equiped with relatively actively face needle plate 5 and end needle plate 6, face needle plate 5 is screwed on the lower surface of end needle plate 6, between face needle plate 5 and end needle plate 6, is installed with thimble 7; The left end side of solid plate 1 and right-hand member side are equiped with respectively an ejection cylinder 8, every go out the cylinder body of oil cylinder 8 be individually fixed in solid plate 1, every go out the piston rod epitaxial end portion of oil cylinder 8 be connected with face needle plate 5 or end needle plate 6 respectively.
Wherein, install fixingly for ease of ejection cylinder 8, the utility model adopts following structural design, is specially: solid plate 1 corresponding every go out oil cylinder 8 be equiped with respectively fixed block 9, every go out the cylinder body of oil cylinder 8 be individually fixed in the fixed block 9 of corresponding side.
When matched moulds, the piston rod of ejection cylinder 8 is pushing tow face needle plate 5 or end needle plate 6 upward, and thimble 7 moves and recess the forming surface of cover half mold insert 3 upward; When die sinking, until moving platen 2 is relative with solid plate 1 open after, the piston rod of ejection cylinder 8 pulls face needle plate 5 or end needle plate 6 down, thimble 7 moves down and plasthetics is exited from cover half mold insert 3 positions.
Comprehensive above-mentioned situation is known, the utlity model has the advantage that compact conformation and volume are little.
Above content is only preferred embodiment of the present utility model, for those of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, this description should not be construed as restriction of the present utility model.
