Technical Field
The utility model relates to the technical field of injection molding processing, in particular to a mold with an automatic ejection mechanism.
Background
Injection molding is a method for producing and molding industrial products. The products are generally produced by rubber injection molding and plastic injection molding. In order to improve the production efficiency, at present, many production enterprises adopt a manipulator to take out an injection molded product from a mold. However, when the manipulator stretches into the mold to take the materials, the manipulator is inconveniently taken due to the limitation of the mold structure, the material taking effect and the material taking efficiency are affected, and the product is possibly damaged.
Accordingly, the prior art is deficient and needs improvement.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects of the prior art and provide a die with an automatic ejection mechanism.
The technical scheme of the utility model is as follows: provided is a mold with an automatic ejection mechanism, including: front mould and back mould of mutual lock, the composition surface on front mould and the back mould is provided with front mould benevolence and back mould benevolence respectively, front mould benevolence and back mould benevolence correspond and are provided with a plurality of die cavities, the front mould is provided with ejection mechanism, ejection mechanism includes: the ejector pins are arranged in the cavity, and the power module drives the ejector pin plate to do reciprocating motion, so that the ejector pins enter the cavity.
Furthermore, the thimbles are uniformly distributed in the die cavity.
Furthermore, each cavity is correspondingly provided with an ejection mechanism.
Furthermore, a plurality of groups of thimbles are arranged on an ejector plate of the ejection mechanism, and each group of thimbles corresponds to one cavity.
Furthermore, a plurality of inclined ejector pins are arranged on the front die and extend out of the die cavity.
Further, the power module adopts an oil cylinder.
Further, the power module adopts a cylinder.
By adopting the scheme, the ejector pin is driven by the power module to move, so that the product is pushed out, the manipulator can conveniently take the material, the material taking efficiency is improved, and the requirement for improving the production efficiency is met.

Detailed Description
The utility model is described in detail below with reference to the figures and the specific embodiments.
Referring to fig. 1, the present invention provides a mold with an automatic ejection mechanism, including: a front mold 1 and a rear mold 2 which are engaged with each other. The joint surfaces of the front die 1 and the rear die 2 are respectively provided with a front die core 11 and a rear die core 21, and the front die core 11 and the rear die core 21 are correspondingly provided with a plurality of cavities 3. The front mold 1 is provided with an ejection mechanism 4. The ejection mechanism 4 includes: the ejector pin mechanism comprises a power module 41 arranged on the front die 1, an ejector pin plate 42 connected with the output end of the power module 41, and a plurality of ejector pins 43 arranged on the ejector pin plate 42. The thimble 43 is disposed in the cavity 3. The power module 41 drives the ejector plate 42 to reciprocate, so that the ejector pins 43 enter the cavity 3.
When injection molding is carried out, materials are injected into the cavity 3 between the front mold core 11 and the rear mold core 21 through the beer nozzle, and injection molding is completed. After the product is formed, the rear mold 2 is separated from the front mold 1, and at the same time, the power module 41 is started to push out the ejector plate 42, so that the ejector 43 extends into the cavity 3, the formed product is pushed out from the cavity 3, and the formed product is taken away by a manipulator. The ejector pin 43 is driven to move through the power module 41, so that a product is pushed out, the manipulator can conveniently take materials, the material taking efficiency is improved, and the requirement for improving the production efficiency is met.
The thimble 43 is uniformly distributed in the cavity 3, so that the force applied to the molded product is uniformly distributed, and the condition that the product is damaged due to uneven stress when the product is pushed out is avoided.
In some embodiments, an ejection mechanism 4 is disposed in each of the cavities 3. An ejection mechanism 4 is correspondingly arranged according to each cavity 3, so that the thrust on the molded product in the cavity 3 is more stable, and the product ejection effect is ensured.
In some embodiments, the ejector plate 42 of the ejector mechanism 4 is provided with a plurality of groups of ejector pins 43, and each group of ejector pins 43 corresponds to one mold cavity 3. The ejection of products in the cavities 3 is realized simultaneously through one ejection mechanism 4, and the number of the arranged mechanisms is reduced, so that the cost is effectively reduced.
The front die 1 is provided with a plurality of inclined ejector pins 44, and the inclined ejector pins 44 extend out from the die cavity 3, so that auxiliary ejection is performed from a certain angle direction, and the ejection efficiency of a product is improved.
The power module 41 adopts an oil cylinder. The oil cylinder is simple in structure and reliable in operation, and can remove a speed reducer when reciprocating, and has no transmission gap, so that the oil cylinder moves stably, the requirement for pushing out a product is met, and the stability for pushing out the product is ensured.
The power module 41 employs a cylinder. The air cylinder is simple in principle and structure, easy to install and maintain, low in requirement on a user, and low in maintenance cost.
In conclusion, the ejector pin is driven by the power module to move, so that the product is pushed out, the manipulator can conveniently take the material, the material taking efficiency is improved, and the requirement for improving the production efficiency is met.
The present invention is not limited to the above preferred embodiments, and any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
