Description

A kind of injection mold of microswitch button

Technical field

The utility model relates to injection mold field, the injection mold of specifically a kind of microswitch button.

Background technique

Nowadays, injection mold has been widely used in the manufacturing of plastic products, and general injection mold is by cover half It is put together with dynamic model, mould inside is equipped with the runner and type chamber being sequentially communicated.When injection molding machine injection molding, by melt through spraying Mouth, runner are sent to type chamber, are opened and are removed after being cooled and shaped.However the button of some microswitches is due to elongate form, it is qualified Rate is relatively low, and efficiency is severely impacted, microswitch button as shown in Figure 1, and internal is hollow structure, and top is cylindrical in shape, And lower part is extended to, lower part has aperture and retention bead, and retention bead is interior, and there are also elongate grooves, in ejection process, often Need secondary injection molding, and it sometimes appear that the case where plastic deforms, is not easy to large batch of production and application, it can not Meet production requirement at this stage.

Summary of the invention

The purpose of this utility model：In order to overcome the drawbacks of the prior art, the utility model provides a kind of production efficiency The injection mold of high, easily manufactured microswitch button.

The technical solution of the utility model：Include solid plate and moving template, is arranged between the solid plate and moving template There are two the sliding block that is oppositely arranged, it is respectively arranged with cover half mold insert and insert in the solid plate and moving template, described two The slide block insert being oppositely arranged is provided between a sliding block, the slide block insert is connected with respective slide, described two cunnings Block mold insert, cover half mold insert and insert cooperatively form type chamber；The cover half mold insert be provided with outside microswitch button top The matched upper impression of wall, the upper surface of the cover half mold insert are provided with sprue, the diagonal distribution respectively of the both ends of the sprue There are secondary channels, the secondary channels are transversely arranged and form comb shape arrangement with sprue, and each secondary channels connect corresponding upper impression Bottom；The slide block insert is provided with the matched lower impressions of microswitch button lower part outer wall and matched convex with aperture Block；The insert, which is equipped with, to be equipped with the matched type core of microswitch button interior, the type in-core through type core inner Thimble, type core two sides are provided with and the matched protrusive board of elongate grooves.

Preferably, type chamber has eight.

Preferably, sliding block controls lateral sliding by connection oil cylinder.

It has the advantages that by adopting the above technical scheme, first, using comb shape arrangement runner carries out side casting, It is provided with eight type chambers again, once-cast can produce eight products simultaneously, improve the injection efficiency of plastic；Second, sliding block, fixed Mould and dynamic model all have corresponding mold insert, have not only saved material cost, but also manufacture easy to process, while replaceable corresponding mold insert note The different plastic of other models is moulded, is suitable for promoting the use of；Third, by reasonably designing, enable the mold once at Type leptosomatic plastic while die sinking, can all be ejected plastic by oil cylinder lateral sliding slide block insert and thimble, Discharging is thorough, and automatic operation is easy, structurally reasonable, easily manufactured.
