The mold structure comprises an upper mold plate 10, a mold core assembly 20, a fixing block 30 and a plurality of first fasteners 40, wherein the upper mold plate 10 is provided with a through groove 101, the through groove 101 penetrates through the upper surface and the lower surface of the upper mold plate 10, the upper mold plate 10 is of a through frame structure, and the shape of the through groove 101 can be square or round; the die core component 20 is assembled in the through groove 101, and the die core component 20 is used for receiving injection molding or casting materials to be molded into a target product; the fixing block 30 is respectively connected with the upper template 10 and the mold core assembly 20, the plurality of first fasteners 40 can be detachably fastened to connect the fixing block 30 with the upper template 10 and detachably fastened to connect the fixing block 30 with the mold core assembly 20, and the first fasteners 40 can be screws or rivets. The screw passes through the fixing block 30 to be in threaded connection with the upper template 10, and the screw passes through the fixing block 30 to be in threaded connection with the die core assembly 20.

In this embodiment, the first fastening member 40 detachably and fixedly couples the fixing block 30 and the upper mold plate 10 together, and detachably and fixedly couples the fixing block 30 and the mold core assembly 20 together. When the die core assembly 20 needs to be replaced, the first fastening member 40 is only required to be taken out from the upper die plate 10 and the die core assembly 20 respectively, and then the die core assembly 20 is replaced with a new die core assembly 20, and the new die core assembly 20 and the fixing block 30 are connected together through the first fastening member 40. In the process of replacing the core assembly 20, the core assembly 20 can be quickly disassembled and assembled by the first fastening member 40 and the fixing block 30 without replacing the upper mold plate 10.

The die core assembly 20 comprises a transition block 21, a die core 22 and a second fastener 23, wherein the transition block 21 is assembled in the through groove 101, the first fastener 40 can be detachably fastened and connected with the fixed block 30 and the transition block 21, and the second fastener 23 can be detachably fastened and connected with the die core 22 and the transition block 21. The mold core 22 is used for receiving injection molding or casting material to form a target product, and only the first fastening member 40 and the second fastening member 23 need to be disassembled to replace the mold core 22, the transition block 21 is taken down from the upper mold plate 10, then the mold core 22 is taken down from the transition block 21, and finally a new mold core 22 is replaced. The transition block 21 also bears the pushing action of the ejector pin 63 and the push rod, the ejector pin 63 and the push rod required by different die cores 22 can be different in model, the transition block 21 needs to be replaced simultaneously according to the different die cores 22, and the transition block 21 plays a transition role, so that the upper die plate 10 is prevented from being replaced.

Specifically, the design structure of the through groove 101 of the upper mold plate 10 reduces the workload of machining the hole on the upper mold plate 10, and the positions and the sizes of the holes of the ejector pin 63, the push rod or the screw through hole on the transition block 21 are different for the mold cores 22 of different products. If the through groove 101 is not formed in the upper template 10 to increase the transition block 21, sometimes a new mold core 22 is replaced, the holes in the upper template 10 may not be aligned, the ejector pins 63, the push rods or the screws cannot be installed, sharing is difficult to achieve, the upper template 10 has to be replaced again, the design of the upper template 10 with the through groove 101 solves the problem, and the ejector pins 63, the push rods or the screw through holes can be randomly changed in the range of the through frame to be matched with the transition block 21 without interference.

The transition block 21 is provided with a limit groove, and the mold core 22 is assembled in the limit groove and is abutted against the side wall of the limit groove. The limiting grooves limit the movement of the mold core 22 from the front, rear, left and right directions, thereby preventing the mold core 22 from shifting during operation and accurately assembling the mold core 22 to a predetermined position. It should be noted that the shape of the position-limiting groove and the shape of the mold core 22 may be different, for example, the position-limiting groove is circular, the mold core 22 is square, and the mold core 22 may also abut against the sidewall of the position-limiting groove, thereby performing the position-limiting function.

The transition block 21 and the upper mold plate 10 are provided with accommodating grooves, and the fixing block 30 is accommodated in the accommodating grooves. Specifically, a part of the accommodating groove falls on the transition block 21, the other part of the accommodating groove falls on the upper die plate 10, and a part of the volume of the fixing block 30 is assembled in the accommodating groove, so that the thickness between the fixing block 30 and the upper die plate 10 is reduced, and the accommodating groove also plays a role in limiting the fixing block 30.

Further, the fixing block 30 is lower than or flush with the top surface of the receiving groove. The effect that sets up like this is exactly to swallow the thickness of fixed block 30 through the storage tank completely to avoid fixed block 30 additionally to occupy the space of mould structure, increase the thickness of mould structure.

The mold core assembly 20 further comprises a pressing block 24, the mold core 22 is pressed on the transition block 21 by the pressing block 24, and the second fastener 23 detachably fixes the pressing block 24 and the transition block 21 to fix the mold core 22 and the transition block 21. The contact area between the pressing block 24 and the mold core 22 is increased relative to the contact area between the second fastener 23 and the mold core 22, and the second fastener 23 presses the mold core 22 through the pressing block 24, so that the mold core 22 can be fixed more stably.

There may be one core assembly 20, two core assemblies 20, three, four, etc. in a mold structure. The mold core assembly 20 is the core of the mold structure, different products can be produced only by replacing the mold core assembly 20, and other parts of the mold structure do not need to be replaced, so that the replacement efficiency of the mold is greatly improved, and meanwhile, the waste of unnecessary parts is reduced.
