Description

The modular syringe injection mould of mode

Technical field

The utility model relates to injection mold technology, in particular to a kind of modular syringe injection mould of mode.

Background technique

Injection molding is that plastic products of various shapes are made using mould for plastics in thermoplastic or thermosetting property material Processing method.For the process of injection molding generally by plastic molten melt, the type by the runner injection mold of mold is intracavitary, then cooling dry Solid is at required shape.Syringe is the plastic part of a kind of volume very little itself.Therefore multiple type chambers are often designed in a mold To realize batch production.In maintenance process, need to remove monolith template cleaning, it is more inconvenient.Just in case respective location Impaired, that will lead to entire replacement, uneconomical.

It is therefore desirable to develop the new mould structure of one kind to solve problem above.

Utility model content

The main purpose of the utility model is to provide a kind of modular syringe injection moulds of mode, can simplify mode and set Meter, facilitates and is safeguarded.

The utility model is achieved through the following technical solutions above-mentioned purpose: a kind of modular syringe injection mould of mode, packet Upper die and lower die are included, the upper mold includes the modular upper cores of array arrangement, and the lower die includes and the upper cores one There is the type core of coolant flow channel in one matched lower die Renhe, the upper cores, the type core split of lower die Renhe form the type of syringe-shaped Chamber.

Specifically, equipped with square four to arrange into glue part in the upper cores, it is every two adjacent between glue part All there is a type chamber, it is described into glue part include an erection part and two beveled tip portions, it is described to have point into being equipped with one in glue part The runner of fork, for the runner from the top of erection part into glue, tip plastic emitting and plastic emitting position from beveled tip portion are located at the type chamber Side wall.

Further, there is insulated space between the outside of the erection part and the upper cores.

Specifically, having cone match between the type core and the lower mode.

By adopting the above technical scheme, the beneficial effect of technical solutions of the utility model is:

This mould structure splits into mode the equal modules unit of structure proximate, simplifies design, facilitates and safeguarded.

Specific embodiment

The utility model is described in further detail combined with specific embodiments below.

Embodiment:

As shown in figures 1 and 3, the modular syringe injection mould of a kind of mode of the utility model, including upper mold 1 and lower die (not marking), the modular upper cores 11 of upper mold 1 including array arrangement, lower die include and the matched lower die one by one of upper cores 11 Benevolence 21 and the interior type core 22 for having coolant flow channel 221, upper cores 11, lower mode 21 and 22 split of type core form the type chamber of syringe-shaped 102.Since mode is modular, as long as so designing a set of mode and replicating and multiple be used as assembled and replacement.Dimension When shield, upper and lower mode removes one by one from template, thus can be carried out and eaily clears up.

As shown in Figures 2 to 4, four of square arrangement are equipped in upper cores 11 into glue part 12, it is every two adjacent into All there is a type chamber 102 between glue part 12, include an erection part 121 and two beveled tip portions 122 into glue part 12, into glue part A forked runner 123 is equipped in 12, runner 123 goes out from the top of erection part 121 into glue from the tip in beveled tip portion 122 Glue and plastic emitting position are located at the side wall of type chamber 102.It is that two of its injecting glue distinguish into glue part 12 for each type chamber 102 From two sides into glue, the melt plastic cement of two sides is converged in centre and becomes whole, and syringe can be formed after solidification；For each into glue For part 12, respectively toward two type chambers, the 102 direction injecting glue for being in 90 °.The injection molding situation of this four type chambers 102 is equivalent, so note Polymer amount is reliable and stable.

As shown in figure 3, having insulated space 111 between the outside and upper cores 11 of erection part 121.Erection part 121 in this way Increase a thermal insulation layer between type chamber 102, excessive heat is avoided to conduct to type chamber 102 and cause cooling slow.

As shown in figure 3, having cone match between type core 22 and lower mode 21.When molding, between type core 22 and lower mode 21 It can combine closely, type chamber 102 is avoided to have leakage to form extra burr.

Above-described is only some embodiments of the utility model.For those of ordinary skill in the art, Without departing from the concept of the present invention, various modifications and improvements can be made, these belong to practical Novel protection scope.
