Embodiment Construction

[0032] The following is attached Figure 1-5 The application is described in further detail.

[0033] The embodiment of the present application discloses an injection mold with an inner arc chamfering demoulding mechanism in the channel, combining figure 1 , figure 2 with image 3 As shown, the left mold 1 and the right mold 2 are included, and the mold cores 3 are embedded on the left mold 1 and the right mold 2, that is, the mold cores 3 are arranged in pairs, and the mold cores 3 are installed and fixed by bolts. During injection molding, a pair of mold cores 3 are generally used for combined injection molding. However, some special-shaped workpieces cannot be demolded, so another mechanism is needed to cooperate with the mold cores 3 for injection molding to facilitate demoulding.

[0034] A side core-pulling mechanism 4 is provided between the left mold 1 and the right mold 2 to cooperate with injection molding and facilitate demoulding, and a positive core-pulling me...

Abstract

The invention discloses an injection mold with a channel inner arc-shaped chamfer demolding mechanism, and relates to the technical field of injection molds. According to the technical solution, the injection mold with the channel inner arc chamfer demolding mechanism comprises a left mold and a right mold, mold cores are fixedly installed on the left mold and the right mold correspondingly, a side core pulling mechanism is arranged between the left mold and the right mold, a front core pulling mechanism and a chamfer demolding mechanism are installed on the right mold, the front core pulling mechanism and the chamfering demolding mechanism are sequentially separated from the same end of a workpiece during demolding, the side core pulling mechanism is separated from the other end of the workpiece, the chamfering demolding mechanism comprises hinge pieces hinged to the mold cores, curved surfaces matching with injection molding to form arc-shaped chamfers is arranged on the hinge pieces, and the side, away from the curved surfaces, of the hinge pieces are attached to the front core pulling mechanism, and the right mold is further provided with a linkage assembly for linking the hinging pieces and the side core pulling mechanism during demolding. The injection mold is reasonable in structure, and the problem that the demolding is difficult due to the fact that the demolding space is limited is effectively solved.

Description

technical field [0001] The present application relates to the technical field of injection molds, in particular to an injection mold with an inner arc chamfering demoulding mechanism in a channel. Background technique [0002] Mold belongs to the intermediate product in the production process and is used for the production of final product. Mold processing is one of the important ways of material forming. Compared with mechanical processing, it has fewer processes, high material utilization rate, low energy consumption, easy production and high efficiency. Advanced features, widely used in automobile, energy, medical, machinery, electronics, aerospace and other industries. With the development of the product market, the styles of injection molding products are becoming more and more diverse, and the quality requirements for products are also getting higher and higher, and more and more problems are encountered. Some products are equipped with side through holes, that is, th...
