Injection mould for studying tool box stationery series

Abstract

The invention discloses an injection mould for studying tool box stationery series, and particularly relates to the technical field of moulds. The injection mould for the studying tool box stationeryseries comprises a lower mould seat. An upper mould seat is arranged at the top of the lower mould seat, a first groove is formed in the top end of the lower mould seat, a clamping groove is formed inthe middle of the first groove, an injection mould plate is movably connected into the clamping groove, and a first clamping block is movably connected between the inner wall of the first groove andthe injection mould plate. According to the injection mould for the studying tool box stationery series, the clamping groove is connected with the injection mould plate in a clamped mode, the injection mould plate is fixed through the first clamping block, the mould plate is conveniently replaced, the mould manufacturing cost is lowered, the motor rotates and is connected with a connecting threaded rod in a transmission mode through a conveyor belt, thus two moving sleeves move oppositely, a pulling rod slides in a sliding sleeve, the upper mould seat is pulled to slide on the outer side of the sliding rod, the lower mould seat and the upper mould seat conveniently work in a corresponding mode, the production efficiency is improved, a raised block is matched with a second groove, a limiting pin and a limiting hole are matched, the raised block, the second groove, the limiting pin and the limiting hole are matched with a buffering cushion to reduce vibration, the upper mould seat is stabilized advantageously, mould crushing is avoided, and the injection quality is improved.

Description

technical field [0001] The invention relates to the technical field of molds, and more specifically, the invention relates to an injection mold for a school kit box. Background technique [0002] The school kit box is a special storage box for primary schools. The school kit box stores some small sticks and balls for counting, or triangular boards. With the improvement of education level, the school kit box has become an indispensable part of education. The box is usually made of plastic material. [0003] The Chinese patent of patent application publication number CN 108790046 A discloses a plastic tray injection molding mold, including a push plate, the center of the push plate is provided with a through hole, the upper mold is arranged on the top of the push plate, and the lower part of the upper mold is provided with a concave hole. Groove, the upper part of the core passes through the through hole of the push plate, and its upper part is inserted into the groove of the...

AI Technical Summary

Problems solved by technology

[0004] However, the plastic tray injection molding mold provided in the above technical solution still has many disadvantages in actual use, such as the need for mold matching during injection molding, which has low efficiency, and a set of molds can only produce one product, resulting in waste of resources.
