Description

A bevel gear injection mold

technical field

The utility model patent relates to a bevel gear injection mold, which belongs to the injection molding mold and is mainly used for thermoplastic injection molding of small bevel gears.

Background technique

Plastic bevel gears have been widely used in various industries such as micro motors, electronic products, auto parts, household appliances, office supplies, toys, etc. Thermoplastic bevel gears are mainly used for injection molding, generally using point gate, three-plate molds, and condensate is commonly used If it is taken out manually, the production efficiency is low, and even stuck, which brings certain difficulties to production.

Contents of the invention

In order to better solve the above problems, an injection mold with spring + push block + fixed distance pull rod mechanism is invented, which can automatically realize the ejection of condensate. The utility model patent provides a mold with simple structure, easy manufacture and convenient operation.

The technical scheme of the utility model patent is: a bevel gear injection mold, including a fixed mold and a movable mold. 1. Distance tie rod 2. Spring 2. Guide sleeve. The guide sleeve and die are placed between the fixed template and the runner plate. The two plates are connected by screws. Spring one is placed in the fixed template, runner plate and fixed mold seat plate, the push block is placed on the runner plate and can move, spring two is on the distance tie rod two, and the right end of the distance tie rod two has a thread for connecting the push block , the fixed distance tie rod two runs through the fixed template and the runner plate; the movable mold consists of a movable template, a reset lever, a reset lever fixed plate, a push plate, a core fixed plate, a spacer, a core, a push tube, a movable mold seat plate, The guide column is composed of the push tube and the reset rod installed on the reset rod fixing plate, the push plate and the reset rod fixing plate are connected by screws, the core is installed on the core fixing plate, and the core fixing plate and the movable mold seat plate are connected by screws , The core runs through the push plate, the reset rod fixed plate, and the movable template, the guide column is installed on the movable template, and the movable template seat plate, spacer and movable template are connected by screws.

The die in the mold is a body of revolution with a fixed shaft shoulder at its right end.

The mold has a simple structure, is easy to manufacture, and is convenient to use, and can realize automatic ejection of condensate, thereby improving production efficiency.

Detailed ways

With reference to accompanying drawing 1, the bevel gear injection mold of the present utility model comprises fixed mold and moving mold, and fixed mold is made of fixed mold seat plate 10, runner plate 11, fixed template 12, die 13, push block 7, fixed distance pull bar- 5. Spring 1 6, distance rod 2 8, spring 2 9, guide sleeve 4, guide sleeve 4, die 13 are placed between the fixed template 12 and the flow channel plate 11, the two plates are connected by screws, and the distance rod The right end of one 5 is interference fit with the fixed mold seat plate 10, the spring one 6 is placed in the fixed template 12, the runner plate 11 and the fixed mold seat plate 10, the push block 7 is placed on the runner plate 11 and can move, the spring two 9 On the distance tie rod 2 8, the right end of the distance tie rod 2 8 has threads for connecting the push block 7, and the distance tie rod 2 8 runs through the fixed template 12 and the runner plate 11; the movable mold is composed of a movable template 15 and a reset rod 16 , reset rod fixed plate 17, push plate 18, core fixed plate 19, cushion block 20, core 22, push tube 23, movable mold seat plate 21, guide post 3, push tube 23, reset rod 16 are installed on the reset On the rod fixing plate 17, the push plate 18 is connected with the reset rod fixing plate 17 with screws, the core 22 is installed on the core fixing plate 19, the core fixing plate 19 is connected with the movable mold seat plate 21 with screws, and the core 22 runs through On the push plate 18, the reset rod fixed plate 17, the movable template 15, the guide post 3 is installed on the movable template 15, and the movable template seat plate 21, the cushion block 20 and the movable template 15 are connected with screws.

The die 13 in the mold is a body of revolution with a fixed shaft shoulder at its right end.

When the mold is opened, the spring one 6 separates the mold along the I parting surface, and the distance tie rod two 8 pulls out the sprue condensate from the sprue sleeve. When the fixed template 12 is limited by the distance tie rod one 5 Finally, the II parting surface starts parting, and the product moves with the movable mold, so the point gate is pulled off, and the spring two 9 pushes the push block 7 to make the runner condensate escape from the runner plate 11 and the distance tie rod two 8. Finally, under the action of the ejector pin of the injection machine, the push plate 18 is driven to push the push tube 3 to push down the product. During mould-closing, the reset rod 16 drives the push tube 23 to reset.
