Description

The plastic mould of anti-mold insert deformation

Technical field

The utility model relates to plastic mould field more particularly to a kind of plastic moulds of anti-mold insert deformation.

Background technique

At the time of molding, plastic cement enters in shaping mold cavity plasthetics from into glue runner, forms after cooling.When plastic cement products When structure is complicated, generally require to carry out assistant formation by mold insert.

Moved in existing, the mold insert on solid plate is only correspondingly arranged in position, degree of cooperation is low between two mold inserts, In Formative stage is easy displacement and deformation occurs, seriously affects the Forming Quality of product, while shortening the service life of mold insert.

Utility model content

The utility model is proposed in view of the above problem of the existing technology, and the utility model provides a kind of using the longevity The long anti-mold insert of life deforms plastic mould.

The utility model is achieved through the following technical solutions: a kind of plastic mould of anti-mold insert deformation comprising dynamic Mould and cover half, the dynamic model are equipped with mavable module core, and the cover half is equipped with fixed mold core, and the mavable module core is corresponding with the fixed mold core Setting；It is correspondingly arranged on the mavable module core and the fixed mold core into glue runner；The mavable module core is equipped with insert, described Fixed mold core is equipped with cover half mold insert；The fixing end of the insert is fixed on the mavable module core, the set of the insert End is connect to be socketed with the cover half mold insert.

Preferably, the cover half mold insert is equipped with abutting end, and the abutting end is equipped with placing groove, and the socket end is socketed in institute It states in placing groove.

Further, annular groove is equipped in the placing groove, the socket end is equipped with elastic parts, and the elastic parts can It slides into the annular groove.

Preferably, the socket end be equipped with elastic parts mounting hole, the elastic parts include Flexible element, guide post and Ball, the Flexible element are mounted in the elastic parts mounting hole, and the Flexible element is connected with the guide post, described Ball is fixedly linked with the guide post.

Further, the Flexible element is spring.

Preferably, the annular groove successively includes step surface, fixed radian section, steady transition and leading in place from the inside to the outside To section.

Further, the inner wall of the same depth direction of the placing groove is equipped with several sliding pearls；The socket end Equipped with interior concave ring, the sliding pearl and the interior concave ring cooperate.

Preferably, the sliding pearl is steel ball.

Further, the socket end is equipped with lead angle far from one end of mavable module core.

Compared with prior art, the socket end of the insert of the utility model and cover half mold insert are socketed, and are effectively improved The stability of mold insert, prevents from being displaced between mold insert, by the way of socket, effectively reinforces the power between two mold inserts Learn intensity, the deformation being effectively prevented between two mold inserts；Combination (or sliding pearl and interior concave ring equipped with annular groove and elastic parts Combination), significantly reduce influence of the mold vibration to two mold inserts, at the same in injection moulding process temperature rise, cause roll pearl Or ball expansion, two mold inserts firmly can be fixed on one piece, and then effectively improve the Forming Quality of product.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model；

Fig. 2 is a kind of enlarged structure schematic diagram of embodiment of I in Fig. 1；

Fig. 3 is the partial schematic diagram of Fig. 2 intermediate annular groove；

Fig. 4 is the enlarged structure schematic diagram of the another embodiment of I in Fig. 1.

Specific embodiment

In order to better understand and implement, according to the present invention will be described in detail below with reference to the accompanying drawings.

As shown in Figure 1, a kind of plastic mould of anti-mold insert deformation comprising dynamic model 4 and cover half 2, the dynamic model 4 are equipped with Mavable module core, the cover half 2 are equipped with fixed mold core, and the mavable module core is correspondingly arranged with the fixed mold core；The mavable module core with it is described Fixed mold core molds shape forming cavity；It is correspondingly arranged on the mavable module core and the fixed mold core into glue runner (not shown)；Institute Mavable module core is stated equipped with insert 3, the fixed mold core is equipped with cover half mold insert 1；The fixing end of the insert is fixed on On the mavable module core, the socket end of the insert and the cover half mold insert are socketed.

The cover half mold insert is equipped with abutting end 12, and the abutting end is equipped with placing groove 13, and the socket end 31 is socketed in institute It states in placing groove.

It should be noted that not showing that the structures such as thimble, ejector retainner plate in the utility model, these structures belong to tradition Design, is not just elaborated in the utility model.

Embodiment one

As shown in Figures 2 and 3, annular groove is equipped in the placing groove, the socket end is equipped with elastic parts, the elasticity Component can slide into the annular groove.

The socket end 31 is equipped with elastic parts mounting hole 35, and the elastic parts includes Flexible element 51, guide post 52 With ball 53, the Flexible element is mounted in the elastic parts mounting hole, and the Flexible element is connected with the guide post, The ball is fixedly linked with the guide post, and the Flexible element is spring.

The annular groove is from the inside to the outside successively including step surface 1211 in place, fixed radian section 1212, steady transition 122 With guide section 123.

It should be noted that Flexible element is in compressive state when the ball of the elastic parts is located at fixed radian section, It can be effectively prevented because mold vibration causes socket end to move, and then effectively improve the Forming Quality of product.
