Abstract

The utility model relates to an injection mold field, in particular to internal thread product demoulding structure in four chambeies of a mould. This demoulding structure, including a fixed plate, the top surface of fixed plate is provided with four pivots no. 1, and these four pivots no. 1 are located four summits of a square respectively, a pivot no. 2 is worn to be equipped with in the center of square by the fixed plate, in four pivots no. 1 respectively the cover be equipped with a driven gear, pivot no. 2 is gone up the cover and is equipped with a driving gear, the driving gear is connected with four driven gear meshings, pivot no. 2 lies in the one end of fixed plate bottom surface and is connected with a servo motor through a drive mechanism, the top of four pivots no. 1 links firmly with a core respectively. The utility model has the advantages that: four pivots no. 1 are located four summits with the square at pivot policy of "literature and art should serve both people and socialism" center, and compact structure can not occupy too many space in the mould, has reduced the cost of mould virtually.

Description

The internal thread product stripping structure in one mould four chamber

Technical field

The utility model belongs to injection mold field, particularly a kind of internal thread product stripping structure of mould four chamber.

Background technology

For the product being threaded structure in inner chamber, the main mode of rotating stripping demoulding that adopts carrys out the demoulding, but in order to enhance productivity, the mould in mould four chamber generally can be adopted to produce.A kind of demolding structure is disclosed in the application documents of the screw product demolding structure (201310430021.2) in mould four chamber disclosed in 2014.01.01, four chambers are in one line, and the equal correspondence of core in each chamber arranges a driven gear, every two driven gears are for arranging a driving gear, when die sinking, oil cylinder drives linear gear rack to do rectilinear motion, now two driving gears rotate, and then drive four driven gear rotating in same directions, final core rotating in same direction, product in die cavity is produced cover half, thus makes product complete the demoulding.But this kind of structure is not only complicated, and four chambers need in one line, cause the length of mould to increase, need the injection machine of relatively high power could set up this mould, virtually add cost, therefore, need badly and improve this kind of structure.

Utility model content

For solving the problems of the technologies described above, it is simple, compact that the purpose of this utility model is to provide a kind of structure, for the internal thread product stripping structure in mould four cavity mould.

For achieving the above object, the technical solution of the utility model is as follows:

The internal thread product stripping structure in one mould four chamber, comprises a fixed head, and the end face of described fixed head is provided with four rotating shafts one, and these four described rotating shafts one lay respectively on foursquare four summits; Described fixed head is equipped with a rotating shaft two in described foursquare center; Four described rotating shafts one are arranged with a driven gear respectively; Described rotating shaft two is arranged with a driving gear; Described driving gear and four described driven gears are connected with a joggle; One end that described rotating shaft two is positioned at described fixed head bottom surface is connected with a servomotor by a transmission mechanism; The top of four described rotating shafts one is connected with a core respectively.

Preferably, described transmission mechanism comprises drive, driven pulley and conveyer belt, and described drive is connected with the main shaft of described servomotor, and described driven pulley is connected with described rotating shaft two.

Compared with prior art, the utility model has the advantages that: four rotating shafts one are positioned on foursquare four summits centered by rotating shaft two, and compact conformation, can not take space too many in mould, virtually reduces the cost of mould.

Accompanying drawing explanation

In order to be illustrated more clearly in the technical scheme in prior art and the utility model embodiment, be briefly described to the required accompanying drawing used in prior art and embodiment description below.

Fig. 1 is the front section view of mop rod handle in prior art;

Fig. 2 is the stereogram of the internal thread product stripping structure in mould four chamber disclosed in the utility model embodiment;

Fig. 3 is the injection mold sectional view of mop rod handle in the production drawing 1 disclosed in the utility model embodiment.

Detailed description of the invention

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.

Shown in Fig. 1 is a kind of mop rod handle, and this handle is cylindrical, and it has inner chamber 11, and the lower semisection of inner chamber is female thread structure 12.

The corresponding mould producing this handle is three template dies in mould four cave, and as shown in Figure 2, it has dynamic model A and cover half B, and dynamic model A forms primarily of moving platen, mavable module core, core A1, demolding structure and ejector retainner plate A2.Above-mentioned demolding structure is the internal thread product stripping structure in mould four chamber, and it comprises a fixed head C1, and the end face of fixed head is provided with four rotating shaft one C2, and these four rotating shafts one lay respectively on foursquare four summits; Fixed head is equipped with rotating shaft two C3 in foursquare center; Four rotating shafts one are arranged with respectively a driven gear C4; Rotating shaft two is arranged with a driving gear C5; Driving gear and four driven gears are connected with a joggle; One end that rotating shaft two is positioned at fixed head bottom surface is connected with a servomotor C6 by a transmission mechanism; The top of four rotating shafts one is connected with a core A1 respectively.Wherein, transmission mechanism comprises drive C7, driven pulley C8 and conveyer belt C9, and drive is connected with the main shaft of servomotor, and driven pulley is connected with rotating shaft two.One end of rotating shaft two passes from driven pulley afterwards and ejector retainner plate A2 is connected, and ejector retainner plate A2 is connected with solid plate by guide pillars and bushes.

During die sinking, move a segment distance after dynamic model, ejector retainner plate A2 moves ahead, and meanwhile, servomotor runs, and four root type core A1 are rotated simultaneously, and product departs from from core A1 under the jacking of ejector retainner plate A2, now just completes the demoulding smoothly.

To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein when not departing from spirit or scope of the present utility model, can realize in other embodiments.Therefore, the utility model can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
