Description

A convenient disassembly and assembly of injection mold base

technical field

The utility model relates to the technical field of mold design, in particular to an injection mold base which is convenient for disassembly and assembly.

Background technique

At present, the application of molds involves every product (such as automobiles, aerospace, daily necessities, electrical communications, medical products and equipment, etc.), as long as there are a large number of products, they will be produced by molds, and the mold base is an integral part of the mold. At present, the precision requirements for mold bases will be determined according to different levels and product needs. Longji and Pingjin mold bases just meet the different needs of various customers and provide suitable supplies.

The mold base is a semi-finished product of the mold, which is composed of various steel plates with matching parts, which can be said to be the skeleton of the entire mold. Since the processing involved in mold bases and molds is very different, mold manufacturers will choose to order mold bases from mold base manufacturers to take advantage of the production advantages of both parties to improve the overall production quality and efficiency.

At present, most of the mold bases are fixed and connected by integral screws. When the mold core is replaced and maintained, it is often necessary to disassemble the whole set of mold bases before the mold core can be taken out. The labor of the workers is light and the labor cost is high.

Utility model content

In order to overcome the above-mentioned shortcomings, the present invention aims to provide a technical solution that can solve the above-mentioned problems.

A convenient disassembly injection mold base, including an upper mold base, an upper template, a lower template, and a lower mold base, the upper template is fixedly connected to the bottom of the upper mold base, the lower template is fixedly connected to the top of the lower mold base, and the upper template is fixedly connected to the top of the lower mold base. The bottom is hollowed out to form a mold cavity, a through hole is formed on the lower template corresponding to the mold cavity, a mold core is arranged in the through hole, the bottom of the lower template is located at the edge of the through hole to form a limit groove, and the bottom of the mold core has a limit groove with a limit groove. The corresponding limit flange, the lower die base is formed with a T-shaped notch horizontally and is attached to the lower template to form a T-shaped chute. The T-shaped chute is provided with a sliding block that slides with it. The bottom of the mandrel touches and lifts the mandrel up.

Further, locking bumps are formed on both sides of the slider, and the locking bumps are provided with locking screws for fixedly connecting the slider with the lower die base.

Further, the bottom power supply located on the flange on the mold core has a positioning block, and the bottom of the lower mold plate is located at the notch of the limit groove to form a positioning groove corresponding to the positioning block.

Compared with the prior art, the beneficial effects of the present utility model are as follows: the utility model has a novel structure, adopts a slider-type supporting structure to fix the mold core on the lower template, and facilitates disassembly, replacement and maintenance of the mold core without the need for a complete set of mold cores. The disassembly of the mold reduces the work brightness of workers and saves labor costs.

Additional aspects and advantages of the invention will be set forth, in part, from the following description, and in part will be apparent from the following description, or learned by practice of the invention.
