The invention solves the technical problems through the following technical means:

the utility model provides a whole core mould assembly structure, includes inner membrance and tang cover, the inner membrance is provided with the assembly groove, the tang cover is provided with the assembly piece with the assembly groove assembly, the bottom of assembly piece is provided with first outer chamfer, assembly groove bottom is provided with the first interior chamfer of assembling with first chamfer.

As an improvement of the technical scheme, the first outer chamfer adopts a 45-degree chamfer.

As an improvement of the technical scheme, a second outer chamfer is arranged at the top end of the assembling groove, and a second inner chamfer assembled with the second outer chamfer is arranged at the top end of the assembling block.

As an improvement of the technical scheme, the second outer chamfer adopts a chamfer of 45 degrees.

As the improvement of the technical scheme, the assembly groove is arranged to be a T-shaped groove and comprises a transverse groove and a vertical groove, the width of the transverse groove is larger than that of the vertical groove, and the second outer chamfer is arranged at the joint of the transverse groove and the vertical groove.

As an improvement of the technical scheme, the joint of the first outer chamfer and the assembling block is in transition through a fillet.

The invention has the beneficial effects that: through being provided with first outer chamfer in the bottom of assembly piece, set up first inner chamfer in assembly tank bottom, assemble with first chamfer, become the compound die point contact (area of contact is very little) by the face contact to reduce the collision of assembly piece and assembly tank inner wall when the compound die, reduce wearing and tearing.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described below, and it is obvious that the described embodiments are a part of the embodiments of the present invention, but not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present.

Examples

As shown in fig. 4-6, the whole core mold assembling structure according to the present embodiment includes an inner film 1 and a spigot sleeve 2, the inner film 1 is provided with an assembling groove 11, the spigot sleeve 2 is provided with an assembling block 21 assembled with the assembling groove 11, a first outer chamfer 22 is provided at the bottom of the assembling block 21, and a first inner chamfer 12 assembled with the first chamfer 22 is provided at the bottom of the assembling groove 11.

By arranging the first outer chamfer 22 at the bottom of the assembling block 21 and the first inner chamfer 12 at the bottom of the assembling groove 11, the die clamping is changed from surface contact into point contact (the contact area is small) by assembling with the first chamfer 22, so that the collision between the assembling block 21 and the inner wall of the assembling groove 11 during die clamping is reduced, and the abrasion is reduced.

The top end of the assembling groove 11 is provided with a second outer chamfer 13, and the top end of the assembling block 21 is provided with a second inner chamfer 23 assembled with the second outer chamfer 13; the surface contact is changed into point contact (the contact area is small) during mold closing, so that the collision between the assembly block 21 and the inner wall of the assembly groove 11 during mold closing is reduced, and the abrasion is reduced.

The first outer chamfer 22 and the second outer chamfer 13 adopt 45-degree chamfers, so that the two ends of the chamfers are well protected, and scratches and abrasion of the chamfers and the groove walls are reduced.

The assembly groove 11 is a T-shaped groove and comprises a transverse groove 18 and a vertical groove 19, the width of the transverse groove 18 is larger than that of the vertical groove 19, and the second outer chamfer 13 is arranged at the joint of the transverse groove 18 and the vertical groove 19.

The joint of the first outer chamfer 22 and the assembling block 21 is in transition through a fillet; the fillet can play the effect that reduces wearing and tearing, and first outer chamfer 22 can play fine support, sealed effect simultaneously.
