Description

Keyboard cover ejection shaping die

Technical field

The utility model relates to arrive keyboard cover production equipment technology, and in particular to a kind of keyboard cover ejection formation Mold.

Background technique

Injection mold is the important process equipment for producing various industrial products, with the rapid hair of plastic mould design industry Exhibition and plasthetics aviation, boat too, the popularization and application of the industrial departments such as electronics, machinery, ship and automobile, product is to mold Requirement it is higher and higher, traditional plastic mould design method can not adapt to successive generations of products and improve quality requirement. Computer aided engineering technology have become plastic cement products exploitation, mold design and product processing in these weak links it is most effective By way of.

In existing keycap ejection shaping die, after keycap injection moulding, mostly uses thimble directly to push up and handle keycap Main body, this is allowed for, and mold runner thimble stroke is long, and product second cosmic velocity is slow, and runner is easy to stick to lead to mixed cave phenomenon on jig； In addition, the cooling time of material head is long since the junction runner of male die core and mother module core becomes larger, it is easy to appear in ejection device Tensile phenomenon influences product quality, or even causes scrap of the product.

Summary of the invention

In view of the deficiencies of the prior art, the purpose of the utility model is to provide a kind of keyboard cover ejection shaping dies, lead to It crosses setting and increases ejecting block in increasing male model pin, can both reduce runner ejector pin stroke, solve that runner is easy to stick to lead on jig Mixed cave phenomenon is caused, and may make that material head is thinning, to reduce cooling time, improves product quality.

In order to achieve the above objectives, the technical solution adopted in the utility model is as follows:

A kind of keyboard cover ejection shaping die, key are: described including the front template and rear pattern plate being correspondingly arranged It is provided with mother module core in front template, male die core is installed in the rear pattern plate, between the mother module core and the male die core It is formed with the product type chamber being adapted with shape of product, is provided centrally with male model pin in the male die core, and the male model is inlayed The upper end of needle is protruded into the runner that the mother module core opens up, and is also equipped in the rear pattern plate below the male die core and institute The striping module that product type chamber is used in combination is stated, the lower end of the rear pattern plate is connected with board, and the bottom of the board passes through mould Foot is fixedly connected with bottom plate, and the thimble module and jacking block knot being used in combination with the striping module are provided in the support block Structure.

Further, the male model pin includes construction section and cone cell section, is opened up on the construction section and the male die core Mounting hole be threadedly coupled, the cone cell section is connected to the upper end of construction section, and the upper end of the cone cell section protrudes from the male model The upper surface of benevolence is arranged.

Further, male model backing plate, the bottom of the male die core are provided between the male die core and the striping module Portion is connected by the male model backing plate with the rear pattern plate.

Further, the thimble module includes the upper thimble panel being stacked from top to bottom, upper Ejector Retainer Plate, lower top Dial plate and lower Ejector Retainer Plate are fixed with thimble on the upper Ejector Retainer Plate and lower Ejector Retainer Plate, which extends upward through institute It states rear pattern plate and to protrude into the product type intracavitary.

Further, the striping module includes push plate bottom plate and the push plate panel on push plate bottom plate, described Demoulding thimble that is through the rear pattern plate and matching with the product type chamber is provided on push plate panel.

Further, the ejecting block is arranged close to the thimble position.

Further, panel is connected with above the front template.

The remarkable result of the utility model is: structure is simple, novel in design, passes through the ejecting block and thimble mould of setting Block, striping module with the use of realize keycap ejection be detached from, effectively reduce runner ejector pin stroke, solve runner it is easy to stick Lead to mixed cave phenomenon on jig；By the way that male model pin is arranged in male die core, and the shape of material head is protruded on the top of the male model pin At position, so that the space of material head present position reduces, namely be the reduction of the cooling time of material head, thus effectively prevent because Material head is cooling bad and causes the tensile phenomenon occurred in ejection device, and then ensure that product quality, reduces rejection rate.
