Abstract
The utility model provides a sand box of a mechanical molding sand core and a die lifting device, which comprise a sand box, a die body and a flat plate, wherein the die body is sleeved in an inner hole of the flat plate and the sand box is placed on the flat plate. The sand box and the life lifting device are characterized by further comprising a support plate, a draw rod, an oblique pin and a bed plate, wherein the draw rod is threaded through the bed plate under the die body and a center hole of the support plate on the sand box, the oblique pin is connected with the draw rod, and the draw rod is fixed on the support plate on the sand box through the oblique pin. The support plate and the oblique pin are driven by the sand box, the oblique pin drives the draw rod and the bed plate, the sand box, the die body and the sand core in the die box and the die body are moved synchronously, the sand core is driven to realize lifting the die from the lower portion to the upper portion, and the sand box and the die lifting device have the advantages that the area of the bed plate for holding sand is bigger when the die is lifted, sand shapes can be effectively protected from damages, the rigidity is good, the operation is convenient and reliable, sand falling is convenient, the production efficiency is high, and the like. The sand box is applicable to medium and small foundry goods.
Description
Technical field
The utility model belongs to the machine casting process unit, particularly a kind of sandbox of machine moulding core and die lifter.
Background technology
Traditional suspended core adopts the arbor core of codding to reach the purpose of molding in the machine casting process unit, as shown in Figure 1, the sandbox of existing mechanical moulding core and die lifter are the devices of a kind of arbor suspended core molding, and as shown in Figure 1, it is made up of sandbox 1, die body 2, arbor 3, flat board 4 etc.Its shortcoming and defect is:
1. suspended core arbor cost of manufacture height, fabrication cycle is long.
2. the versatility of suspended core arbor is subjected to the restriction of product and sandbox size.
3. the suspended core arbor is yielding, and service life is short.
4. knockout difficulty.
5. can not stack when sandbox is put, influence the production scene management.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of prior art, provides a kind of easy to operate, can protect sand mold effectively, the sandbox and the die lifter of the machine moulding core of enhancing productivity.
The sandbox and the die lifter of a kind of machine moulding core of the utility model change traditional mode with the molding of arbor suspended core, adopt the mode of pull bar, supporting plate stooling, to reach the purpose of smooth molding.Concrete technical scheme is as follows:
A kind of sandbox of machine moulding core and die lifter comprise sandbox, die body, flat board, and described die body is sleeved in the dull and stereotyped endoporus, and sandbox is placed on the flat board; Be characterized in: also comprise gripper shoe, pull bar, taper pin and supporting plate; Described pull bar be passed under the die body supporting plate with at the centre bore of sandbox upper backup pad, taper pin is connected with pull bar, and by taper pin pull bar is fixed on the gripper shoe on the sandbox.
The sandbox and the die lifter of a kind of machine moulding core of the utility model have following advantage:
1. the area of supporting plate holder sand is bigger during the rising molding, can effectively protect sand mold to avoid damaging.
2. rigidity is good, and convenient and reliable operation is applicable to middle-size and small-size foundry goods.
3. knockout is convenient, the production efficiency height.
4. cost of manufacture is low, and the cycle is short.
Description of drawings
Fig. 1 is the device schematic diagram of existing arbor suspended core molding.
Fig. 2 is a structural representation of the present utility model.
Wherein: sandbox 1, die body 2, arbor 3, flat board 4, core 5, gripper shoe 6, pull bar 7, taper pin 8, supporting plate 9, lead 10, guide pad 11 and guide pin bushing 12
The specific embodiment
As shown in Figure 2, the sandbox and the die lifter of a kind of machine moulding core of the utility model, 1, a kind of sandbox and die lifter of machine moulding core, comprise sandbox 1, die body 2, dull and stereotyped 4, described die body is sleeved in the dull and stereotyped endoporus, and sandbox is placed on the flat board; It is characterized in that: also comprise gripper shoe 6, pull bar 7, taper pin 8 and supporting plate 9; Described pull bar be passed under the die body supporting plate with at the centre bore of sandbox upper backup pad, taper pin is connected with pull bar, and by taper pin pull bar is fixed on the gripper shoe on the sandbox.
Evenly distribute in sandbox 1 outside and be provided with two or four guiders with dull and stereotyped 4, described guider is by the lead 10 that is fixed on the flat board, with the guide pad 11 that is located at the sandbox outside, and guide pin bushing 12 compositions of in the guide pad endoporus, adorning, described lead 10 inserts in the described guide pin bushing 12 when sandbox is placed on the flat board.
The utility model is when molding: drive gripper shoe and taper pin by sandbox, taper pin drives pull bar and supporting plate, and the core 5 in sandbox 1, die body 2 and sandbox and the die body is synchronized with the movement, and the moving core 3 of holder is realized molding from bottom to top.
