Abstract

The utility model discloses a demoulding mechanism of lid portion of participating in, but include with two pendulum rods of thimble board swivelling joint, the cover half is pulled and the core, the core with fixed die plate fixed connection and being formed with in both sides can allow the perforation of walking of pendulum rod upper end perforation upper portion be formed with on the fixed die plate with the outside of pendulum rod on domatic matching guide face on the perforation lower part be formed with on the core with the lower guide of inboard domatic matching down of pendulum rod. The utility model discloses a demoulding mechanism adopts two pendulum rods upper end and last guide face and the cooperation guide of guide face down, realizes ejecting die sinking, has fine adaptability to this kind little lid that the volume degree of depth is little, and the mechanism is simple moreover, and control is convenient, has realized ejecting and the synchronization drawing of patterns having improved production efficiency.

Description

The mould emptier of lid pin part

Technical field

This utility model is related to technology of die manufacturing field, more particularly to a kind of mould emptier of lid pin part.

Background technology

Engineering plastics, such as glass fibre reinforced nylon, such as PA+GF30 are a kind of food stage macromolecular materials, due to its life Efficiency high is produced, consume energy low, light specific gravity, non-corrosive, the features such as corrosion-resistant, also be used for being molded the various products of making by some manufacturers Product, such as water meter, general product structure are complicated, and the spare and accessory parts of needs are more, are such as accomplished by covering in one kind in water meter, for ease of card Embedding connection, typically on this, with the multiple pin parts of lid lower surface are integrally formed in, described pin part includes interval setting to lid Two pins, the height of pin is general less than one centimetre and spacing is less, how to carry out demoulding design to this small-sized upper lid Become the technical problem for being badly in need of solving.

Utility model content

The purpose of this utility model is, for technological deficiency present in prior art, and to provide a kind of lid pin part Mould emptier.

To realize that the technical scheme adopted by the purpose of this utility model is：

A kind of mould emptier of lid pin part, including two forks being rotatably connected with ejector retainner plate, cover half is pulled and type Core, described core are fixedly connected with described solid plate and are formed with wearing that described fork upper end can be allowed to walk in both sides Hole, is formed with the domatic upper guide surface for matching on the outside with fork in described perforated upper, on solid plate described Perforated lower is formed with the lower guide surface matched with the inner side Caused by Sloping Surfaces of described fork on core.

Insert is respectively arranged with domatic and inner side Caused by Sloping Surfaces on described outside.

Contiguous block is fixedly installed on described ejector retainner plate, described fork lower end can with described contiguous block by bearing pin It is rotatably connected.

Step-like limiting stand is correspondingly formed with the medial surface upper end of fork in described core lateral surface upper end.

Compared with prior art, the beneficial effects of the utility model are：

Mould emptier of the present utility model, is guided using cooperation of two fork upper ends with upper guide surface and lower guide surface, Ejection mold-opening is realized, the lid little for this small size depth has good adaptability, and mechanism is simple, and control is just Profit, realizes the synchronization of ejection and the demoulding, improves production efficiency.

Description of the drawings

Fig. 1 show the structural representation of the mould emptier of lid pin part of the present utility model；

Fig. 2 show the A-A cross section views shown in Fig. 1；

Fig. 3 show mould emptier schematic diagram.

Specific embodiment

This utility model is described in further detail below in conjunction with the drawings and specific embodiments.It should be appreciated that this place The specific embodiment of description only to explain this utility model, is not used to limit this utility model.

As Figure 1-3, the mould emptier of lid pin part of the present utility model 10 includes being rotatably connected with ejector retainner plate 1 Two forks 2, cover half pulls 3 and core 4, and described core is fixedly connected with described solid plate and is formed with and can permit in both sides Perhaps the perforation that described fork upper end is walked, is formed with solid plate in described perforated upper domatic on the outside with fork The upper guide surface of 21 matchings, is formed with core in described perforated lower and is matched with the inner side Caused by Sloping Surfaces 22 of described fork Lower guide surface.Core constitutes injection chamber with the medial surface of fork upper end, it is preferable that to carry out lower limit, described The lateral surface upper end of core is correspondingly formed limited location platform with fork medial surface upper end, and described limiting stand is preferably one-level or two Level it is step-like, using two-stage step be capable of achieving level to vertical Dual positioning, it is ensured that injection quality.

Wherein, it is to improve service life, on domatic on described outside and inner side Caused by Sloping Surfaces, is respectively arranged with insert, inlays The setting of block, improves convertibility, reduces processing cost.

Specifically, be fixedly installed contiguous block 5 on described ejector retainner plate, described fork lower end by bearing pin with it is described Contiguous block be rotatably connected, realize that fork is connected with the transition of ejector retainner plate by contiguous block, adjustment is convenient and is easily installed.

The above is only preferred implementation of the present utility model, it is noted that general for the art For logical technical staff, on the premise of without departing from this utility model principle, some improvements and modifications can also be made, these change Enter and retouch also to should be regarded as protection domain of the present utility model.
