Abstract
The utility model relates to the technical field of die casting machines, particularly relates to a die-casting mold core-pulling device convenient for maintenance. The die-casting mold core-pulling device convenient for demounting and mounting comprises a core seat and an oil cylinder, and the oil cylinder is fixedly connected with a bearing plate; the die-casting mold core-pulling device convenient for demounting and mounting is provided with a connecting shaft I, a connecting shaft II, and a coupler, wherein one end of the connecting shaft I is fixedly connected with the core seat and the other end is connected with the coupler, and one end of the connecting shaft II is in threaded connection with the oil cylinder and the other end is connected with the coupler; and the oil cylinder is connected with the core seat through the connecting shaft I, the connecting shaft II, and the coupler including two half couplers parting along the axial direction. The only requirement for the die-casting mold core-pulling device to be maintained is to dismount the coupler and take out the core seat and the core, so that the demounting and mounting are convenient.
Description
Technical field
The utility model relates to the die casting machine technical field, easy-to-dismount compression mod core-pulling device especially easy to maintenance.
Background technology
The employed compression mod of die casting machine, because the needs of workpiece shape, standing have and the inconsistent pellet of compression mod body stripping direction, this can be disclosed from notification number CN2808361Y, the utility model that is used for the center casting mould of horizontal plunger die casting machine obtains understanding, these pellets must be extracted out in advance, and the compression mod body just can carry out stripping operation; Because size, shape, the quantity of pellet differ, so often pellet is fixed on the pellet seat; Behind the foundry goods casting forming, foundry goods is wrapped in the pellet working surface, and contact force is bigger, needs the very big power of loosing core just can make the pellet seat drive pellet and extracts out from foundry goods; Prior art is connected the oil cylinder that is fixed on the support plate as shown in Figure 1 with the pellet seat, make the pellet seat drive pellet as the power of loosing core and extract out from foundry goods; Its weak point is: when needing repairing, must remove oil cylinder and just can take out pellet seat and pellet, and very inconvenient.
The utility model content
The purpose of this utility model is not easy-to-dismount deficiency when overcoming existing compression mod core-pulling device maintenance, and a kind of easy-to-dismount compression mod core-pulling device is provided.
Concrete technical scheme of the present utility model is:
Easy-to-dismount compression mod core-pulling device comprises pellet seat, oil cylinder, and described oil cylinder is fixedlyed connected with support plate; Described easy-to-dismount compression mod core-pulling device has connecting axle one, connecting axle two, shaft coupling; Described connecting axle is held one by one with the pellet seat and is fixedlyed connected, and the other end is connected with shaft coupling; Described connecting axle 21 ends are threaded with oil cylinder, and the other end is connected with shaft coupling.Oil cylinder is connected with the pellet seat by connecting axle one, connecting axle two, shaft coupling, when needing repairing, just can take out pellet seat and pellet as long as remove shaft coupling, and is very convenient.
As preferably: described shaft coupling is made of two half a couplers, and screw connects between two half a couplers; Described half a coupler faying face is provided with semicircle orifice, and described semicircle orifice is provided with groove; Described connecting axle one is provided with rounded ends one, bar portion one; Described connecting axle two is provided with rounded ends two, described bar portion two; Described rounded ends one and rounded ends two and groove matched in clearance; Described groove axial length and rounded ends one and rounded ends two length sums are adaptive; Described bar portion one and bar portion two grow shaft coupling two ends respectively; Described bar portion two is provided with screwed hole and oil cylinder is adaptive.Described shaft coupling is made of two half a couplers that separate vertically, makes dismounting more convenient.
As preferably: described screw is four, and described half a coupler is provided with screw counter bore.Connect firm.
The beneficial effects of the utility model are:
Oil cylinder is connected with the pellet seat by the shaft coupling that connecting axle one, two, two half a couplers that separate vertically of connecting axle constitute, and when needing repairing, just can take out pellet seat and pellet as long as remove shaft coupling, makes dismounting very convenient.
Description of drawings
Fig. 1 is the structural representation of existing compression mod core-pulling device;
Fig. 2 is a structural representation of the present utility model;
Fig. 3 is the A-A cutaway view of the utility model shaft coupling.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Shown in accompanying drawing 2, accompanying drawing 3: easy-to-dismount compression mod core-pulling device, oil cylinder 5 is fixedlyed connected with support plate 7; Shaft coupling 3 is made of two half a couplers 31, and half a coupler is provided with four screws 6 connections between 313, two half a couplers of screw counter bore; The half a coupler faying face is provided with semicircle orifice 311, groove 312; Connecting axle 1 is provided with rounded ends 1, and connecting axle 22 is provided with rounded ends 2 21, rounded ends one and rounded ends two and groove matched in clearance; Groove axial length and rounded ends one and rounded ends two length sums are adaptive; Connecting axle 1 is provided with bar portion 1, and bar portion one fixedlys connected with pellet seat 4; Connecting axle 22 is provided with bar portion 2 22, screwed hole 23, and bar portion one and bar portion two grow shaft coupling two ends respectively; Screwed hole 23 is connected with oil cylinder 5.
Easy-to-dismount compression mod core-pulling device with the connection of oil cylinder by connecting axle one, connecting axle two, shaft coupling, makes the pellet seat drive pellet and extracts out from foundry goods; When needing repairing,, take away shaft coupling as long as remove attachment screw between two half a couplers; Just can take out pellet seat and pellet and keep in repair, very convenient.
