Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a general mold structure. Background Art

[0002] At present, a mold is a tool that makes a blank into a workpiece with a specific shape and size under the action of external force. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the outer shape of an article by changing the physical state of the rubber material. It has the title of "the mother of industry" and is widely used in blanking, die forging, cold heading, extrusion, powder metallurgy part pressing, pressure casting, and the forming processing of compression molding or injection molding of products such as engineering plastics and rubber. At the same time, when a mold injects and forms a workpiece with patterns, it is necessary to add a template with patterns to the injection mold cavity of the mold so that the surface of the injected and formed workpiece has patterns.

[0003] However, the existing mold structure is poorly designed. The mold often only has a template with one kind of pattern. Moreover, since the outer shapes of some workpieces are the same, but the patterns to be formed are different, workpieces with the same outer shape but different patterns require additional molds with corresponding patterns, thus increasing the manufacturing cost of the molds, reducing the production efficiency of the workpieces, having poor practicability, and a small scope of application.

[0004] Therefore, it is necessary to study a new technical solution to solve the above problems. Summary of the Utility Model

[0005] In view of this, in view of the deficiencies of the existing technology, the main purpose of the utility model is to provide a general mold structure, which disassembles and installs the corresponding pattern template on the installation cavity according to the requirements of the workpiece pattern, and cooperates with the positioning structure to realize the matching and positioning of the pattern template, so that workpieces with the same outer shape but different patterns do not require additional molds with corresponding patterns, thereby reducing the manufacturing cost of the molds, being beneficial to improving the production efficiency of the workpieces, and having a wide scope of application.

[0006] To achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A general mold structure includes a first mold base, a second mold base, and a pattern template. Among them: the first mold base can be closed on the second mold base. A cavity is provided on the second mold base. A positioning cavity is provided on the side of the first mold base opposite to the cavity of the second mold base. A positioning structure is provided in the positioning cavity. The pattern template is adaptively positioned on the positioning structure and is detachably arranged on the positioning cavity through a connecting piece. The pattern template has a core, and an injection mold cavity for injecting and forming a workpiece is formed between the core and the cavity.

[0008] As a preferred solution, a mounting seat is arranged in the positioning cavity, and the positioning structure is arranged on the mounting seat.

[0009] As a preferred solution, the positioning structure includes positioning posts. A plurality of positioning posts are arranged at intervals along the periphery of the mounting seat. Positioning holes matching the positioning posts are arranged on the texture template, and the positioning posts are adapted to the positioning holes.

[0010] As a preferred solution, a pouring system is further included. The pouring system includes a pouring runner and a sub-runner. The pouring runner is arranged on the first mold base, and the sub-runner is arranged on the second mold base and communicated with the cavity. When the first mold base and the second mold base are clamped, one end of the pouring runner is communicated with the sub-runner through a discharge port.

[0011] As a preferred solution, the pouring runner is arranged in a gradually increasing manner from the outside to the inside towards the discharge port.

[0012] As a preferred solution, the other end of the pouring runner is provided with a feed port, and the outer end of the feed port is provided with a concave arc surface for matching contact with the feed head.

[0013] As a preferred solution, a mounting cavity is arranged on the first mold base, a material guiding member is arranged in the mounting cavity, the pouring runner is arranged on the material guiding member, the material guiding member is in a T shape, a mounting step is arranged on the inner wall of the mounting cavity, the material guiding member includes a mounting portion and a guide post arranged on the mounting portion, and the mounting portion is detachably arranged on the mounting step.

[0014] Compared with the prior art, the present utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solutions, it mainly disassembles and assembles the corresponding texture template on the mounting cavity according to the requirements of the workpiece texture through the design of each component, and cooperates with the positioning structure to realize the matching positioning of the texture template, so that workpieces with the same shape but different textures do not need to be additionally equipped with molds with corresponding textures, thereby reducing the manufacturing cost of the molds, being beneficial to improving the production efficiency of the workpieces, having strong practicability and a wide application range;

[0015] In addition, the setting of the concave arc surface enables the feed head to be positioned and connected with the feed port after contacting the concave arc surface, so as to ensure the accurate connection between the feed head and the feed port and ensure the stability of the subsequent glue injection process. At the same time, the setting of the material guiding member facilitates the subsequent replacement and maintenance of the pouring runner, ensures the stable use of the mold, and has good usability.
