Abstract
The utility model discloses a magnetic body injection molding mechanism for automatically demolding a threaded core. The mechanism comprises a mold (1) and a threaded core (2), a push pipe (3) is installed at a connecting position between an inner chamber of the mold (1) and the threaded core (2), a large chain wheel (4) is installed at the bottom of the threaded core (2), the large chain wheel (4) and a small chain wheel (6) are connected through a chain (5), and the small chain wheel (6) is connected with a motor (7). The magnetic body injection molding mechanism for automatically demolding the threaded core has the advantages that the structure is compact, the transmission is smooth, feasibility, stability, practicability and the like of the structural design are achieved, the design is reasonable, the operation is convenient, and accuracy requirements of a workpiece can be met.
Description
Technical field
The utility model relates to a kind of magnet injection moulding apparatus, particularly a kind of magnet injection moulding mechanism of automatically deviating from thread core.
Background technology
In the magnet injection moulding process, all there are the inside and outside threaded design of tool in a lot of magnet products and daily product, and solving plastic screw thread release problems is the key of this type of Design of Dies.In general, processing the plastic screw junction has two class methods: a class is in the situation that plastic and resin allow, and adopts the method for deviating from by force; One class is that screw thread is dark, mechanical strength of resin is high, the demanding plastic of accuracy of thread, the method that must adopt rotation to deviate from.Take off in rotation and to be divided into again in the helicitic texture manually deviating from and automatically to deviate from two kinds.In the prior art, rely on the workman to place thread core during injection moulding fully, it also is artificial taking out, and efficient is low, cost is high, and also there are some quality hidden danger in simultaneously manually-operated.
The utility model content
The purpose of this utility model namely is to overcome the deficiencies in the prior art, and a kind of production automation degree mechanism that thread core is deviate from magnet injection moulding high, simple to operation automatically is provided.
The purpose of this utility model is achieved through the following technical solutions: the mechanism of thread core is deviate from the magnet injection moulding automatically, comprise mould, thread core, at dies cavity and thread core joint ejector sleeve is installed, bottom at thread core is equipped with hinge wheel, hinge wheel is connected by chain with minor sprocket, and minor sprocket links to each other with motor.
The utility model has the advantage of: take off thread mechanism and adopt chain gear transmission automatic trip thread mechanism, this project organization is compact, stable drive; The problems such as feasibility, stability and practicality of structural design have been solved; Reasonable in design, easy to operate can satisfy the required precision of product.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Among the figure, 1-mould, 2-thread core, 3-ejector sleeve, 4-hinge wheel, 5-chain, 6-minor sprocket, 7-motor, 8-magnet product.
The specific embodiment
Further describe the technical solution of the utility model below in conjunction with accompanying drawing, but the content that the utility model is protected is not limited to the following stated.
As shown in Figure 1, the mechanism of thread core is deviate from the magnet injection moulding automatically, comprise mould 1, thread core 2, at mould 1 inner chamber and thread core 2 joints ejector sleeve 3 is installed, in the bottom of thread core 2 hinge wheel 4 is installed, hinge wheel 4 is connected by chain 5 with minor sprocket 6, and minor sprocket 6 links to each other with motor 7.
The utility model adopts automatic rotation to take off screw device, and ejector sleeve 3 tops contact with magnet product 8, and after injection moulding was finished, motor 7 drove thread core 2 and is rotated down, and simultaneously, ejector sleeve 3 maintains static magnet product 8, magnet product 8 can be deviate from thread core 2.Because not sliding in chain 5 transmission process, transmission size is compact, do not need very large tensile force, the load that acts on axle is less, efficient is higher, relatively is fit to the requirement of transmission in the mould, and chain, sprocket wheel, motor are purchased conveniently on the market, do not need special processing, so in driven Design, adopted chain drive.The form that chain gear transmission is taken off thread mechanism is: finishing what take off screw thread is the threaded portion of gear shaft, and two gear shafts are driven by the gear wheel of jackshaft, and jackshaft is by driven by motor by chain wheel driving mechanism.
Claims (1)
1. the mechanism of thread core is deviate from the magnet injection moulding automatically, it is characterized in that: it comprises mould (1), thread core (2), at mould (1) inner chamber and thread core (2) joint ejector sleeve (3) is installed, in the bottom of thread core (2) hinge wheel (4) is installed, hinge wheel (4) is connected by chain (5) with minor sprocket (6), and minor sprocket (6) links to each other with motor (7).
