Technical Field

The utility model relates to a silica gel product preparation technical field especially relates to a make things convenient for sacculus mould of drawing of patterns.

Background

Because silica gel has the material characteristics of flexibility, more and more products are made of silica gel materials. At present, products like some sacculus (like milk filling ware), gasbag (like the gasbag of sphygmomanometer etc.) class are hollow, if the middle part diameter of this kind of product is far greater than oral area diameter, can appear the problem that is difficult to the drawing of patterns after the completion of moulding plastics, and then lead to being difficult to the volume production.

SUMMERY OF THE UTILITY MODEL

The embodiment of the utility model provides a technical problem that will solve lies in, provides a make things convenient for sacculus mould of drawing of patterns to make things convenient for the drawing of patterns.

In order to solve the technical problem, the embodiment of the utility model provides a make things convenient for sacculus mould of drawing of patterns is provided, including interior mold core, last mould and lower mould, set up respectively on lower mould and the last mould with first half of sacculus and the fore-groove and the back groove that latter half corresponds, the fore-groove that the lower mould was passed in the correspondence of interior mold core top, form the one-tenth die cavity that matches with the sacculus between interior mold core, fore-groove and the back groove, upward be equipped with the injecting glue hole that leads to with the back groove mutually on the mould, be equipped with the air flue of intercommunication top and bottom in the interior mold core.

The mold comprises a lower mold seat and a mold core seat, wherein the inner mold core is arranged on the mold core seat, the side surface of the mold core seat is provided with air holes communicated with an air passage of the inner mold core, guide frames corresponding to the mold core seat are arranged on two sides of the lower mold seat, the mold core seat is arranged between the guide frames on the lower mold seat, and the mold core seat can move up and down along the guide frames.

Furthermore, a guide groove is formed in the die core seat, and a guide post penetrating through the guide groove is correspondingly arranged on the lower die seat.

Furthermore, the inner mold core, the front groove and the rear groove are all provided with a plurality of groups to form a plurality of groups of molding cavities.

The utility model has the advantages that: the utility model discloses a set up the air flue in the inner mold core, blow through the air flue and make fashioned silica gel sacculus inflation, and then the quick drawing of patterns of being convenient for, simple structure can be applicable to large batch production.

Description of the reference numerals

The balloon molding machine comprises a balloon 1, an upper mold 10, a rear groove 11, a glue injection hole 12, a lower mold 20, a front groove 21, a lower mold seat 22, a guide frame 23, guide columns 24, an inner mold core 30, an air passage 31, a mold core seat 32 and air holes 33.

Detailed Description

It should be noted that, in the present application, the embodiments and features of the embodiments may be combined with each other without conflict, and the present invention is further described in detail with reference to the accompanying drawings and specific embodiments.

In the embodiment of the present invention, if there is a directional indication (such as upper, lower, left, right, front, and rear … …) only for explaining the relative position relationship between the components and the motion situation under a specific posture (as shown in the drawing), if the specific posture is changed, the directional indication is changed accordingly.

In addition, the descriptions of the first, second, etc. in the present invention are for descriptive purposes only and are not to be construed as indicating or implying any relative importance or implicit indication of the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature.

Referring to fig. 1 to 7, a balloon mold facilitating demolding according to an embodiment of the present invention includes an inner mold core, an upper mold and a lower mold.

The lower die and the upper die are respectively provided with a front groove and a rear groove corresponding to the front half part and the rear half part of the balloon, the top of the inner die core correspondingly penetrates through the front groove of the lower die, a forming cavity matched with the balloon is formed among the inner die core, the front groove and the rear groove, the upper die is provided with a glue injection hole communicated with the rear groove, and the inner die core is internally provided with an air passage communicated with the top and the bottom. Liquid silica gel is injected through the glue injection hole of the upper die, vulcanization molding is carried out, air is injected into the air passage through the air pump after cooling molding, the molded balloon is expanded, and demolding is facilitated. During specific implementation, the bottom of the inner mold core can also be provided with an air nozzle communicated with an air passage, so that the air pump is conveniently connected through an air pipe.

As an implementation mode, the balloon mold further comprises a lower mold base and a mold core base, the inner mold core is arranged on the mold core base, air holes communicated with an air passage of the inner mold core are formed in the side face of the mold core base, guide frames corresponding to the mold core base are arranged on two sides of the lower mold base, the mold core base is arranged between the guide frames on the lower mold base, and the mold core base can move up and down along the guide frames. When the mold is specifically implemented, the mold core seat is driven by the machine to move up and down, so that the inner mold core is driven to perform a demolding action.

As an implementation mode, the die core seat is provided with a guide groove, and the lower die seat is correspondingly provided with a guide post penetrating through the guide groove. The stability of inner mold core when moving is further promoted in the cooperation of guide way and guide post.

As one implementation mode, the inner mold core, the front groove and the rear groove are all provided with a plurality of groups, and a plurality of groups of forming cavities are formed. The utility model has the advantages of simple structure, the quick drawing of patterns when can realize a plurality of sacculums is applicable to large batch production.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
