Description

Technical Field

[0001] The utility model relates to the technical field of production and processing of injection molds, in particular to a mold-saving jig for injection molds. Background Art

[0002] During the production and processing of plastic molds with high appearance requirements (such as high gloss, textured surfaces, etc.), improper mold protection often leads to enlarged parting surfaces of the product, resulting in larger sizes of the injection molded products.

[0003] In existing technology, mold reduction is typically performed by placing the workpiece, such as the mold core, directly on a workbench and performing the reduction manually or with auxiliary equipment. During the reduction process, improper operation by the reduction operator can result in the parting surface being enlarged, leading to an increase in the clamping gap. This can necessitate surface reduction or mold core rework, significantly increasing mold and production costs.

[0004] Therefore, the existing technology has defects and needs to be improved. Utility Model Content

[0005] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a mold-saving jig for an injection mold.

[0006] The technical solution of the present utility model is as follows: a mold-saving jig for an injection mold is provided, comprising: a jig main body, the jig main body being movably mounted on the mold core of the mold, the jig main body being provided with a plurality of mold-saving holes, the mold-saving holes corresponding to the positions of the clamps on the mold core, and the sizes of the mold-saving holes corresponding to the sizes of the clamps on the mold core.

[0007] Furthermore, a plurality of positioning holes are provided on the jig body, and pins are provided on the mold core corresponding to the positioning holes, and the pins are movably embedded in the positioning holes.

[0008] Furthermore, the jig body is provided with a plurality of mounting holes, and the mold core is provided with threaded holes corresponding to the mounting holes. Screws are passed through the mounting holes and locked in the threaded holes, thereby fixing the jig body to the mold core.

[0009] By adopting the above solution, the utility model uses the jig body to protect the mold core clamp, and the mold hole provides a reference for the mold saving position, thereby avoiding the situation where the clamp is damaged during mold saving, reducing the number of unnecessary mold repairs caused by mold saving errors, effectively reducing production costs, ensuring mold product quality, and saving mold development time. At the same time, the jig body is reusable and can be used again during subsequent mold changes for other reasons, eliminating waste. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 It is a structural diagram of the present utility model.

[0011] Figure 2 It is a cross-sectional schematic diagram of the present utility model. DETAILED DESCRIPTION

[0012] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0013] See also Figure 1 、 Figure 2 The utility model provides a mold-saving jig for an injection mold, comprising: a jig body 1, the jig body 1 being movably mounted on a mold core 2 of the mold, the jig body 1 being provided with a plurality of mold-saving holes 11, the positions of the mold-saving holes 11 corresponding to the positions of the clamps 21 on the mold core 2, and the sizes of the mold-saving holes 11 corresponding to the sizes of the clamps 21 on the mold core 2.

[0014] In this embodiment, the jig body 1 is directly mounted on the mold core 2, which is convenient and compact, does not occupy any space outside the mold, and is convenient and compact. At the same time, the jig body 1 is easy to process and has low material requirements. It can avoid situations such as the clamp 21 being enlarged or rounded due to irregular movements when saving the mold alone, thereby ensuring the quality of the saved mold. In addition, the jig body 1 has a simple structure, requires few accessories, and has high reliability. It is possible to choose to set up a jig corresponding to a saved mold position, or to share a jig for multi-hole product molds, or to open multiple saved mold holes 11 on a jig that can meet different clamps 21 on the same mold to meet different needs.

[0015] In some embodiments, the jig body 1 is provided with a plurality of positioning holes 12, and the mold core 2 is provided with pins 22 corresponding to the positioning holes 12, and the pins 22 are movably embedded in the positioning holes 12. The pins 22 provide a guiding and positioning function for the jig body 1, so that when the jig body 1 is set on the mold core 2, the matching of the pins 22 and the positioning holes 12 improves the positioning accuracy between the clamping opening 21 of the mold core 2 and the pattern-saving hole 11 on the jig body 1, thereby meeting the precision requirement for pattern-saving of the clamping opening 21.

[0016] In some embodiments, the jig body 1 is provided with a plurality of mounting holes 13, and the mold core 2 is provided with threaded holes 23 corresponding to the mounting holes 13. Screws are passed through the mounting holes 13 and tightened in the threaded holes 23 to fix the jig body 1 to the mold core 2. The screws are used to lock the jig body 1 and the mold core 2 together to prevent the jig body 1 from shifting during the mold reduction process, which would affect the mold reduction effect.

[0017] In summary, the present invention protects the mold core clamping jaws with the jig body, and uses the mold hole as a reference for the mold saving position. This prevents the clamping jaws from being damaged during mold saving, reduces the number of unnecessary mold repairs caused by mold saving errors, effectively reduces production costs, ensures mold product quality, and saves mold development time. Furthermore, the jig body is reusable and can be used again during subsequent mold changes for other reasons, eliminating waste.

[0018] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
