Abstract

The utility model provides the blow mold that a kind of material embryo and plastic insert will not be bonded.Blow mold containing plastic insert, including inserts pressing plate, blow needle, plastic insert and flatter, the plastic insert is arranged in flattering, and inserts pressing plate and blow needle are provided on the plastic insert.The utility model is by changing the blowing direction on blow needle and increasing the inserts pressing plate of fixed plastics inserts, make to expect that embryo expands outwardly in dropping process, to make to expect embryo far from plastic insert, prevent to expect that embryo is be bonded with inserts generations, it is effective to solve the problems, such as to expect that embryo is Nian Jie with inserts and cause to form or qualification rate is low.

Description

Blow mold containing plastic insert

Technical field

The utility model relates to a kind of blow molds, more particularly to the blow mold after a kind of increase plastic insert.

Background technique

With the raising of market development and customer demand, some blow molds are also required to production plastic insert knot in blow molding Structure meets product requirement.Increase plastic insert structure in blow mold, often because inserts compares at a distance from material embryo Small, generally 6mm-15mm and plastic insert position are not capable of fixing, cause material embryo and inserts bonding, so as to cause product without Method molding or scrappage are high.

Utility model content

The technical problem to be solved by the utility model is to provide the blow molding dies that a kind of material embryo and plastic insert will not be bonded Tool.

The utility model technical scheme applied to solve the technical problem is: the blow mold containing plastic insert, including embedding It part pressing plate, blow needle, plastic insert and flatters, the plastic insert is arranged in flattering, and is provided on the plastic insert embedding Part pressing plate and blow needle.

Further, pneumatic control valve is provided on the inserts pressing plate.

Further, the inserts pressing plate is symmetrical arranged multiple.

Further, blow needle control valve is provided on the blow needle.

Further, multiple ventholes are provided on the blow needle.

Further, the blow needle is symmetrical arranged multiple.

Further, the inserts pressing plate by pressure control make plastic insert be fixed on inserts pressing plate cannot on move down It is dynamic.

Further, the inserts pressing plate passes through pressure control and rotates to push down or unclamp plastic insert.

The beneficial effects of the utility model are: by changing the blowing direction on blow needle and increasing the embedding of fixed plastics inserts Part pressing plate makes to expect that embryo expands outwardly in dropping process, to make to expect embryo far from plastic insert, prevents to expect that embryo and inserts generation are viscous It connects, effectively solves the problems, such as that expecting that embryo is Nian Jie with inserts causes to form or qualification rate is low.

Detailed description of the invention

Fig. 1 is main view of the utility model with part section.

Fig. 2 is the top view of Fig. 1.

Inserts pressing plate is opened when Fig. 3 is work and picks and places the schematic diagram of injection molding inserts.

When Fig. 4 is work inserts pressing plate push down injection molding inserts after prepare converted products when schematic diagram.

Specific embodiment

As shown in Figure 1, the blow mold of the utility model includes inserts pressing plate 2, blow needle 3, plastic insert 4 and flatters 5, modeling The material setting of inserts 4 is being flattered in 5, and inserts pressing plate 2 and blow needle 3 are provided on plastic insert 4, is provided on inserts pressing plate 2 Pneumatic control valve 7, inserts pressing plate 2 can be symmetrical arranged it is multiple, in Fig. 1-2 be shown be provided with 4 inserts pressing plates 2, in blow needle 3 On be provided with blow needle control valve 6, be provided with multiple ventholes on blow needle 3, blow needle 3 can be symmetrical arranged multiple, show in Fig. 1-2 Be be provided with left and right two blow needles 3.The effect for flattering 5 is supporting plastic inserts 4 and inserts pressing plate 2, allows to expect embryo 1 and modeling Expect that inserts 4 combines.

When work, plastic insert 4 is put into and is flattered in 5, as shown in Figure 3；The pneumatic control valve 7 of inserts pressing plate 2 is opened, it is embedding Part pressing plate 2 is fixed on plastic insert 4 on inserts pressing plate 2, cannot be moved up and down, as shown in Figure 4 by pressure control；It opens Blow needle control valve 6 makes blow needle 3 blow outward, while falls to material embryo 1 and flattering 5 bottoms, and the air-flow that blow needle 3 is blown outward makes Expect that embryo 1 is expanded toward mold cavity direction, far from plastic insert 4, to achieve the purpose that expect that embryo 1 is not bonded injection molding inserts 4；Conjunction is closed Mold cavity opens mold after product pressure maintaining, cooling and shaping, close the pneumatic control valve 7 of inserts pressing plate 2, takes out product.Pass through Such a process solves the problems, such as that material embryo 1 is Nian Jie with plastic insert 4 and causes to form or scrappage is high.

The utility model can also be such that 4 inserts pressing plates 2 rotate by pressure control, push down or unclamp plastic-embedded to reach The purpose of part 4 picks and places plastic insert 4 to facilitate.
