The existing injection molding machine template generally adopts a traditional Chinese character 'mi' type structure or a box type structure for having enough strength, the weight of the template is relatively heavy, and the stress of the template is relatively concentrated, so that the service life of the injection molding machine template can be influenced.
In order to further reduce the weight of the template, improve the strength of the template and meet the national requirements of energy conservation and emission reduction, the template of the existing injection molding machine is required to be further improved and lifted.
Disclosure of Invention
The invention aims to solve the technical problem of providing the template structure of the injection molding machine, which can remarkably reduce the weight of the traditional Chinese character 'mi' type template and box type template structure, can improve the strength of the template, is convenient to hoist, and has the characteristics of correspondingly improved service life of the mold and the like.
In order to achieve the above purpose, the technical scheme adopted by the invention is as follows:
an injection molding machine template structure, its characterized in that: the template comprises a template front plate, a template reinforcing rib, a template rear plate and a pull rod seat which are sequentially stacked, wherein a plurality of cavities which are symmetrically distributed along the center of the template are formed among the template front plate, the template reinforcing rib and the template rear plate, the template reinforcing rib is connected with the pull rod seat through double ribs, hollow cavities are formed and connected with a pull rod hole, and a center hole (a feed cylinder inlet hole or a middle jacking pinhole) is formed in the centers of the template front plate, the template reinforcing rib and the template rear plate; one side of the cavity away from the center of the template is communicated with the external environment.
The template reinforcing ribs of the template of the injection molding machine are connected with the pull rod seat through double ribs, and hollow cavities are formed to be communicated with the pull rod holes and communicated with the external environment.
The template reinforcing rib of the injection molding machine template is provided with a plurality of through casting holes.
The template of the injection molding machine is characterized in that a plurality of through casting holes are formed in the template rear plate, and the template front plate is free of casting holes.
The injection molding machine template comprises template feet, wherein the template feet are positioned at the bottom of the template.
The injection molding machine template also comprises lifting ribs which are arranged at the upper, lower, left and right parts of the template front plate and the template rear plate and symmetrically arranged according to the central hole, and a relatively large cavity is formed to be connected with the external environment.
The beneficial effects are that:
the invention provides a lightweight structure of an injection molding machine template, wherein lifting ribs are connected with a front template plate and a rear template plate, and are provided with larger cavities, so that steel wire ropes can be conveniently penetrated during lifting, the lifting time is saved, and the weight of the template is reduced; the template reinforcing ribs are connected with the pull seat through the double ribs, so that the stress of the template is more uniform, and the service life of the die can be prolonged; when the template reinforcing ribs are connected with the pull rod seat through the double ribs, the pull rod seat is not made into a traditional annular solid structure, but the middle part of the template reinforcing ribs connected with the pull rod seat through the double ribs is made into a hollowed-out structure, and the hollow structure is connected with the pull rod holes to form a large cavity, so that the weight of the template is reduced; a plurality of casting holes are arranged on the template, so that the sand core is convenient to fix, sand removal is convenient, and the weight of the template is also reduced.

Detailed Description
The invention will be further illustrated with reference to specific examples. It is to be understood that these examples are illustrative of the present invention and are not intended to limit the scope of the present invention. Further, it is understood that various changes and modifications may be made by those skilled in the art after reading the teachings of the present invention, and such equivalents are intended to fall within the scope of the claims appended hereto.
The invention provides a template light-weight structure of an injection molding machine, which comprises a template front plate, template reinforcing ribs and a template rear plate which are sequentially stacked, wherein a plurality of cavities which are symmetrically distributed along the center of the template are formed among the template front plate, the template reinforcing ribs and the template rear plate, the middle parts of the template reinforcing ribs are annular, the template reinforcing ribs and a pull rod seat are arranged in a double-rib mode and are symmetrically distributed relative to the center of the template, and the centers of the template front plate, the template reinforcing ribs and the template rear plate are provided with center holes (melt adhesive cylinder inlet holes or middle top pin holes); one side of the cavity away from the center of the template is communicated with the external environment.
