Referring to fig. 1-2, the utility model provides a rear template, include: the rear template comprises a rear template body 3 and a plurality of rear template inserts, wherein the rear template inserts are spliced on the rear template body 3, and the rear template inserts and the rear template body form a mold core frame.

In the embodiment, the rear template body 3 and the rear template inserts are arranged and processed separately, so that the problem of warpage and deformation of the processed rear template caused by the use of a material with low iron content is solved. And the rear template is split into the rear template body 3 and a plurality of rear template inserts, so that the problem that the verticality cannot be guaranteed due to elastic knives in the process of machining the deep-barrel rear template can be solved.

In this embodiment, the plurality of rear template inserts include a first insert 1 and a second insert 2, the first insert 1, the second insert 2 and the rear template body 3 respectively form a first travel groove 32 and a second travel groove 33, and the first travel groove 32 and the second travel groove 33 are used for fixing a travel seat.

In this embodiment, the first insert 1, the second insert 2 and the rear mold plate body 3 form the first slide groove 32 and the second slide groove 33, that is, the slide seat is fixed by the first insert 1 and the second insert 2, which is more beneficial for assembling the mold insert, and the first slide groove 32 and the second slide groove 33 are formed by the first insert 1, the second insert 2 and the rear mold plate body 3, so that the slide seat is easily taken out from the corresponding slide groove, and the finished injection molded part can be conveniently taken out after the slide seat is taken out.

In this embodiment, the rear template body 3 is further provided with a groove, the rear template insert is provided with a projection engaged with the groove, and the position of the rear template insert is limited by the engagement of the projection and the groove. For example, in FIGS. 1-2: the first protrusion 11 is engaged with the first groove 34, the second protrusion 21 is engaged with the second groove 35, the third protrusion is engaged with the third groove 36, and the fourth protrusion is engaged with the fourth groove 37. The embedding through lug and recess can avoid back template insert to take place relative displacement on back template body 3, is unfavorable for operating personnel to the equipment of using this mould.

In this embodiment, the bottom of the mold core frame is a recessed portion 31 in the rear mold plate body 3, and the recessed portion 31 is used to limit the position of the mold core. The recessed portion 31 facilitates the operator to quickly assemble the mold core, i.e. the position of the mold core is precisely determined by the recessed portion 31. It should be understood that the rear template body 3 may not have the recessed portion, and the rear template insert and the rear template body 3 may form a mold core frame, where the recessed portion is only for assembling by an operator.

In this embodiment, the plurality of rear template inserts are connected to the rear template body 3 by a bolt structure. The bolt structure comprises a fixing bolt arranged on the rear template insert and a screw hole arranged on the rear template body 3. The number of the bolt structures is not limited, so that the rear template inserts can be firmly fixed on the rear template, and the processing of injection molding parts is not influenced.

In this embodiment, the rear mold plate body 3 further includes a row seat groove 38, and the row seat groove 38 is disposed between two adjacent rear mold plate inserts and located at a side edge of the mold core frame. By arranging the slide seat groove 38, the slide seat can be embedded on the rear template, so that the rear template and the slide seat can be matched conveniently.

In this embodiment, the first insert 1 and the second insert 2 are both provided with concave grooves, and the concave grooves are arranged oppositely and form a mold core frame with the rear mold plate body 3. Because the area of the formed mold core frame attached to the mold core is too small, the position of the mold core is not convenient to limit, and the first insert 1 and the second insert 2 are provided with concave grooves, so that the contact area between the side edge of the mold core frame and the mold core is deepened, and the subsequent processing of injection molding parts is facilitated.

In this embodiment, the rear mold plate inserts further include a third insert 4 and a fourth insert, and the third insert 4 and the fourth insert are disposed on two sides of the long side of the mold core frame. The third insert 4 and the fourth insert are used for limiting the position of the die core on the rear die plate body 3, and the third insert 4 and the fourth insert are oppositely arranged and are arranged between the first insert 1 and the second insert 2. On the other hand, the rear mold plate body 3 may be formed with a row groove, and the row seat may be fixed between the row grooves by the row groove and the third row groove 34 and the fourth row groove 35 formed in the foregoing, so that the position of the row seat may be restrained and further the processing may be facilitated.

Further, the material of the rear template is medium carbon steel. For cost reasons, medium carbon steel with a low iron content may be used as the material constituting the rear mold plate. For example: S55C, P20 and the like. Because the mode that a plurality of rear template inserts are connected with the rear template body 3 is used, the stress in the processing process is greatly reduced, and the warping deformation is not easy to cause, so in order to consider the cost and the environmental protection, materials with lower iron content, such as medium carbon steel, can be used.

The utility model also provides a mould, including the back template of above-mentioned structure. Specifically, the structure further comprises a line seat, a mold core and a front template, when the mold is assembled, the mold core is placed in the concave part 31 of the rear template body 3, then the line seat is used for fixing the mold core, then the line seat and the mold core are fixed through the rear template insert, and finally the structure is fixed through the front template. And obtaining the required mould, and processing the injection molding piece by the mould.

The utility model has the advantages that: the split of the original integrally-processed rear template is divided into the rear template body 3 and the rear template inserts for processing, so that the problem of warpage and deformation of the processed rear template caused by the material with lower iron content is solved. And the rear template is split into the rear template body 3 and a plurality of rear template inserts, so that the problem that the verticality cannot be guaranteed due to elastic knives in the process of machining the deep-barrel rear template can be solved.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the scope of the claims of the present invention.
