Injection mold with interchangeable ejector pin structure

Abstract

The invention discloses an injection mold with an interchangeable ejector pin structure. The injection mold comprises an upper mold plate and a lower mold plate, an upper mold core is arranged at the lower end of the upper mold plate, the lower mold plate is provided with a lower mold core correspondingly matched with the upper mold core, a mold cavity is formed between the lower mold core and the upper mold core, and at least two vertical ejector pins are arranged at the lower end of the mold cavity; and two parallel notch planes are formed in the upper end of each ejector pin, a groove is formed in the lower end of each ejector pin, a correspondingly matched buckle is arranged at the side end of each groove, and the upper ends of the buckles are connected with buckle springs. The two parallel notch planes are arranged at the upper end part of each ejector pin, so that the ejector pins can be conveniently clamped by a wrench to rotate and replace; through rotation of the ejector pins, the buckles are separated from the grooves, and the ejector pins are conveniently pulled out and replaced; and therefore, the injection mold has the advantages that the design is novel, the structure is simple, the problem of how to quickly replace and exchange mold cores and parts related to products when different plastic products are produced is solved, the cost can be saved, and the working efficiency can be improved.

Description

Technical field [0001] The present invention relates to the field of mold, and in particular, to an injection mold of an interchangeable thimble structure. Background technique [0002] Mold factories and companies often have a product and similar product in the development of product development; some products are cases of local upgrading improved product performance. Considering the cost problem of mold manufacturing when the customer is facing this phenomenon, considering the cost of mold manufacturing, often designed to interchange the structure on the injection mold, or the design of local top needles and insert interchange, this design is used A total of the same form of formula and the structure of the interchanged model reached a variety of plastic products production, which can save mold costs. [0003] However, in the production of different plastic products, it is necessary to disassemble the mold, install the modified and related parts of the product, and the efficien...
