The core pulling mechanism can realize core pulling at different angles, and meets the requirement of multi-angle core pulling that a plurality of core pulling mechanisms cannot be arranged due to space limitation.
Description
The invention is a divisional application of invention patent application with the application number of 2017113851335, the application date of 2017, 12 and 20 and the name of 'injection mold multi-angle laminated core-pulling mechanism'.
Technical Field
The invention relates to the technical field of injection molds, in particular to a multi-angle core pulling mechanism of an injection mold.
Background
The core-pulling mechanism is one of the most common mechanisms in the injection mold, and is generally designed at the back-off position of the product. The core pulling mechanism commonly used at present is that the oblique guide pillar drives the slider of loosing core and looses core, and when moving the cover half and opening, the slider of loosing core motion is driven to the oblique guide pillar for the core breaks away from the product and is convenient for the product drawing of patterns. However, the conventional core-pulling slider driven by the inclined guide post can only move along one direction, and when the core is pulled longitudinally in a small space range and in multiple directions, the conventional core-pulling scheme is not applicable any more.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provides a multi-angle core pulling mechanism of an injection mold.
The technical scheme adopted by the invention for realizing the aim of the invention is as follows:
injection mold multi-angle mechanism of loosing core, including lower hydro-cylinder, transmission slider and two lower sliders of loosing core, the transmission slider by the hydro-cylinder drives down slide in the movable mould, the transmission slider is kept away from the terminal surface of lower hydro-cylinder is made lambda font, equal fixed mounting has the slider of leading on two inclined planes of transmission slider lambda font terminal surface, every slider of loosing core down is close to the terminal surface system of transmission slider has the spout of leading, lead on the slider system have with the spout complex slide board of leading, the inside buckle of two cell wall tops of spout of leading catches on the slide board, the hydro-cylinder is also installed down on the movable mould, multi-angle mechanism of loosing core top has last slider and slider to lead the slide, it is in by last hydro-cylinder drive to go up the slider to loose core the slide in the slider guide slide, wherein slider guide slide and last hydro-cylinder are all installed on the movable mould.
Compared with the prior art, the core pulling mechanism can realize core pulling at different angles, and meets the requirement of multi-angle core pulling that a plurality of core pulling mechanisms cannot be arranged due to space limitation.

Detailed Description
The invention is further described with reference to the following drawings and detailed description. As shown in fig. 1-5, the multi-angle core pulling mechanism of the injection mold comprises a movable mold 1 and a fixed mold 2, the multi-angle core pulling mechanism is arranged on the movable mold 1, the multi-angle core pulling mechanism comprises a lower oil cylinder 6, a transmission slide block 7 and two lower core pulling slide blocks 8, the transmission slide block 7 is driven by the lower oil cylinder 6 to slide in the movable mold 1, the transmission slide block 7 is far away from the end surface of the lower oil cylinder 6 and is made into an inverted V shape, guide slide blocks 9 are fixedly installed on two inclined surfaces 71 of the inverted V-shaped end surface of the transmission slide block 7, each lower core pulling slide block 8 is close to the end surface of the transmission slide block 7, a guide slide groove 81 is formed in the end surface of the transmission slide block 7, a guide slide plate 91 matched with the guide slide groove 81 is formed in the guide slide block 9, the tops of two groove walls of the guide slide groove 81 are. The multi-angle core pulling mechanism is characterized in that an upper core pulling sliding block 3 and a sliding block guide sliding seat 4 are arranged above the multi-angle core pulling mechanism, the upper core pulling sliding block 3 is driven by an upper oil cylinder 5 to slide in the sliding block guide sliding seat 4, and the sliding block guide sliding seat 4 and the upper oil cylinder 5 are both installed on the movable die 1.
After the mold is opened and before the product is demolded, the lower oil cylinder 6 drives the transmission slide block 7 to slide downwards in the movable mold 1 (as shown in fig. 3), the two lower core-pulling slide blocks 8 can only slide towards the left lower side and the right lower side respectively under the limitation of the sliding track in the movable mold 1, and in the process, the guide slide plate 91 on the guide slide block 9 also slides in the guide slide groove 81 to ensure that the two lower core-pulling slide blocks 8 normally slide to realize the complete core-pulling. In the core-pulling process of the lower core-pulling slide block 8, the upper oil cylinder 5 also drives the upper core-pulling slide block 3 to slide for core-pulling, so that core-pulling at different angles in the longitudinal direction and the transverse direction is realized.
In the above technical scheme, the slide block guide slide 4 is fixed with the hold-down strip 10, which can prevent the upper core-pulling slide block 3 from separating from the slide block guide slide 4.
In the above technical solution, the fixed mold 2 is provided with a lock module 21 for locking the transmission slide 7 during mold closing. In the injection molding process of the product, a large mold locking force is needed, and the lock module 21 is configured to automatically lock the transmission slide block 7 after the injection mold is closed, so that the lower oil cylinder 6 only needs a common oil cylinder instead of a mold locking oil cylinder, and the cost is greatly reduced.
The foregoing detailed description of the preferred embodiments of the invention has been presented. It should be understood that numerous modifications and variations could be devised by those skilled in the art in light of the present teachings without departing from the inventive concepts. Therefore, the technical solutions that can be obtained by a person skilled in the art through logic analysis, reasoning or limited experiments based on the prior art according to the concept of the present invention should fall within the scope of the present invention.
