A kind of separate template that is used on the plastic injection molding equipment
Technical field
The present invention relates to a kind of template, particularly a kind of separate template that is used on the plastic injection molding equipment.
Background technology
With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4; At present; Opening and closing die device on the plastic injection molding equipment when performances such as the rigidity that needs template, intensity when higher; Usually be made of one the formula structure to template fagging of indication of the present invention 1 and template backing plate 2, though that this kind way can improve its weak point of template stress performance is obvious:
(1), integral structure causes structure crowded and complicated, brings difficulty for the foundry goods moulding.
(2), integral structure need cause physical dimension big because of moulding, is difficult for processing and waste material.
(3), integral structure can not transform on existing machine its template stress performance is improved, must the new template of specialize, be unfavorable for the transformation of second-hand machine, be unfavorable for a tractor serves several purposes, the scope of application is restricted greatly.
Summary of the invention
In order to overcome the deficiency of prior art, the object of the present invention is to provide a kind of separate template that is used on the plastic injection molding equipment.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of separate template that is used on the plastic injection molding equipment; It comprises template fagging and template backing plate; The installed surface of said template fagging and template backing plate is provided with a plurality of mounting grooves; Said template backing plate is provided with and the mutual corresponding installing hole of mounting groove, passes installing hole, mounting groove through mounting screw between said template fagging and the template backing plate and is connected and fixes;
As the further improvement to above-mentioned embodiment, the installed surface outer periphery of said template backing plate is equipped with and slot to make way.
The invention has the beneficial effects as follows: the present invention is owing to be decomposed into two independently parts with template fagging, template backing plate; Thereby make after the template split structure separately greatly simplify, the foundry goods moulding is easy, in addition; Physical dimension reduces; Convenient processing is saved material, thereby can be widely used on the fixed form or collapsible form on the plastic injection molding equipment.

The specific embodiment
With reference to Fig. 5~Figure 10; A kind of separate template that is used on the plastic injection molding equipment; It comprises template fagging 1 and template backing plate 2, and said template fagging 1 is provided with a plurality of mounting grooves 11 with the installed surface of template backing plate 2, and said template backing plate 2 is provided with and mounting groove 11 mutual corresponding installing holes 21; Between said template fagging 1 and the template backing plate 2 through mounting screw 3 pass installing hole 21, mounting groove 11 is connected fixing; Certainly, according to actual needs, mounting screw 3 can also adopt other common connecting pieces to replace.
Template is owing to adopt the split manufacturing, so can manufacture new template fagging 1, template backing plate 2 when making; Also can utilize the common moving platen or the solid plate of existing machine to make template fagging 1; Only need new processing template backing plate 2 just can constitute separate template with its connection; Remove template backing plate 2 and can work as the common templates use again, help the transformation of existing machine, can a tractor serves several purposes.When using collapsible form, its template fagging 1 can be along direction slippage on the machine matrix of guider regulation; When as fixed form, 1 of its template fagging is affixed with the machine matrix.
In addition; The template of common injection machine makes the die deformation that is installed on it corresponding also big because stress deformation is big, is easy to generate defectives such as overlap during moulded plastic products; Usually the method for eliminating this defective is to increase mold clamping force; But mold clamping force increases the corresponding increase of power of injection machine consumption makes manufacturing cost improve, and when increasing clamp force to the maximum prescribed value of injection machine, has just had only the injection machine of changing big specification if also need increase.And the use separate template, the installed surface outer periphery of said template backing plate 2 is equipped with and slot to make way 22, thereby makes template and die deformation little, has avoided goods overlap to occur, does not also need to increase clamp force naturally, has directly widened the scope of application of injection machine.
The present invention is owing to be decomposed into two independently parts with template fagging 1, template backing plate 2; Thereby make after the template split structure separately greatly simplify, the foundry goods moulding is easy, in addition; Physical dimension reduces; Convenient processing is saved material, thereby can be widely used on the fixed form or collapsible form on the plastic injection molding equipment.
