Detailed ways

Below, in conjunction with accompanying drawing and specific embodiment, the utility model is described further:

A kind of mold frame that is convenient to demoulding as shown in Figure 1, comprises upper mold base 10, lower mold base 20, moving plate 30 and static plate 40, concrete moving plate 30 is arranged on the bottom of upper mold base 10, corresponding The static plate 40 is arranged on the top of the lower mold base 20 . The above-mentioned upper mold base 10 can move toward the lower mold base 20 to guide the moving plate 30 to fit the static plate 40 . A thimble 11 is also provided on the upper mold base 10, one end of the thimble 11 is movably connected in the upper mold base 10, and the other end of the thimble 11 is movably connected on the movable plate 30, and can be moved by the bottom of the movable plate 30. end sticks out. In addition, a first elastic member 50 is clamped between the ejector pin 11 and the upper die base 10 , and a second elastic member 60 is clamped between the moving plate 30 and the upper die base 10 . The above-mentioned first elastic member 50 is used to provide the first elastic stress to move the thimble 11 away from the upper die base 10 , and the second elastic member 60 is used to provide the second elastic stress to make the moving plate 30 move away from the upper die base 10 The elastic coefficient of the first elastic component 50 is made smaller than the elastic coefficient of the second elastic component 60 , that is, the force required for deformation of the first elastic component 50 is smaller than the force required for deformation of the second elastic component 60 .

On the basis of the above structure, when using the convenient mold base of the utility model, the upper mold base 10 can be moved toward the lower mold base 20 to realize the lamination of the moving plate 30 and the static plate 40, that is, mold closing. During this process, the easily deformable first elastic member 50 is compressed before the second elastic elastic member, so that the thimble 11 is withdrawn from the movable plate 30, preventing the thimble 11 from affecting the production of the product. Thereafter, the upper die base 10 continues to move downward, and the second elastic member 60 also begins to deform, so that the moving plate 30 moves toward the upper die base 10. In this way, the second elastic member 60 can play a certain buffering role to prevent the moving plate from 30 is in rigid contact with upper die holder 10.

After the product is made, the upper mold base 10 is reset, that is, demoulding, and the first elastic stress provided by the first elastic member 50 can make the thimble 11 far away from the upper mold base 10, and the product on the movable plate 30 will be ejected from the ejection plate. 30, and the second elastic stress provided by the second elastic member 60 can make the moving plate 30 away from the mold base, and further make the products on the moving plate 30 separate from it. And because the elastic coefficient of the first elastic member 50 and the elastic coefficient of the second elastic member 60 are different, the first elastic stress and the second elastic stress can eject the product successively, so that the demoulding effect is better and the demoulding efficiency is higher.

Preferably, a slag discharge groove 41 and a slider 42 can be provided on the static plate 40, and the slag discharge groove 41 extends to the edge of the static plate 40; 41 in the direction of extension. In the actual production process, such as stamping molding or injection molding, general products will produce residues, which will affect the next production, so a slag discharge groove 41 can be set on the static plate 40. 41 to receive, drive the slider 42 to slide along the slag discharge groove 41 to the edge of the static plate 40, and the residue in the slag discharge groove 41 can be discharged.

More specifically, the above-mentioned slider 42 can be made of wear-resistant material, and the slider 42 is more wear-resistant and has a longer service life.

Preferably, an elastic rubber block can be provided at the bottom of the thimble 11, and the elastic rubber block is in flexible contact with the product to prevent damage to the product.

Preferably, in this embodiment, the mold base for easy demoulding also includes a guide mechanism 70 for guiding the movement of the upper mold base 10 towards the lower mold base 20, so that the movement between the upper mold base 10 and the lower mold base 20 more temperature. Specifically, the guide mechanism 70 includes a guide sleeve 71, a guide rod 72 and a third elastic member 73, the guide sleeve 71 is fixed on the bottom of the upper die base 10; the guide rod 72 is fixed on the top of the lower die base 20; The top end of the rod 72 is movably connected in the guide sleeve 71 ; the third elastic member 73 is clamped between the top end of the guide rod 72 and the bottom wall of the guide sleeve 71 . In this way, the arrangement of the third elastic component 73 can slow down the motion inertia of the guide rod 72 and the guide sleeve 71 , making the use process safer and the service life longer.

Further, the inner side wall of the above-mentioned guide sleeve 71 is provided with a limiting portion 711, and correspondingly, the outer wall of the guide rod 72 is provided with an abutment portion 721, specifically the abutment portion 721 can move to the position of the guide sleeve 71 when the guide rod 72 moves At the exit, it abuts against the limiting portion 711 to prevent the guide rod 72 from detaching from the guide sleeve 71, and the guide structure is stable.
