Abstract

The utility model relates to a mould benevolence structure of convenient polishing, mould benevolence include die cavity mould and core mould two parts, the die cavity mould set up in the front template, the core mould set up in the back template, the core mould be the triplex, merge the equipment by core mould one, core mould two, core mould three and form, core mould one and die cavity mould all form product appearance face, the parting line after the assembly is located product appearance face, core mould two, three assembly back formation product inner structure of core mould. According to the die core structure convenient for polishing, the partial die core die with the ornament appearance surface is assembled with the die cavity die firstly, so that the appearance polishing surface and the parting line can be seen, the integral polishing operation is convenient, the defect that the appearance polishing surface is subjected to size deviation or the parting line is subjected to acute angle blunting (rounding) when the appearance polishing surface and the parting line are polished independently is effectively overcome, the high appearance quality of the ornament and the stability of the injection molding efficiency are ensured, and the injection molding cost of the ornament is reduced.

Description

Mould benevolence structure of convenient polishing

Technical Field

The utility model relates to a mould benevolence structure, especially a mould benevolence structure of convenient polishing.

Background

The mold core is communicated with a cavity and a mold core in the injection mold, the cavity mold generates external structural features of a plastic product, the mold core mold generates internal structural features, a complete plastic product injection molding cavity is formed after mold closing, the injection molding cavity is invisible, and a mold closing contact surface of the cavity mold and the mold core mold is called a parting surface. In practice, the injection molding defects which easily occur on the parting surface mainly include flashes (burrs) and breaks, and one reason is that the appearance polished surface size deviation or the acute angle of the parting surface becomes blunt (round) caused by independent polishing of a cavity and a core mold. The defects directly affect the visual quality, touch feeling and size of a plastic part product, particularly for automobile inner handle type ornaments, a cavity and a core mould form appearance surfaces, and once the position of a parting surface has size deviation or acute angle becomes blunt (round), the injection molding ornaments cannot be accepted.

SUMMERY OF THE UTILITY MODEL

The utility model discloses an overcome above-mentioned technical problem, provide a mould benevolence structure for final product is level and smooth on the outward appearance face does not have the flaw.

The technical scheme of the utility model is that: the mold core structure convenient for polishing comprises a mold cavity mold and a mold core mold, wherein the mold cavity mold is arranged in a front mold plate, the mold core mold is arranged in a rear mold plate, the mold core mold comprises three parts, the mold core mold comprises a mold core mold I, a mold core mold II and a mold core mold III which are combined and assembled to form a product, the mold core mold I and the mold cavity mold form an appearance surface of the product, a parting line after assembly is located on the appearance surface of the product, and the mold core mold II and the mold core mold III are assembled to form an inner structure of the product.

Further, the first mold core mold and the first mold cavity mold are assembled through a frustum and a positioning column.

And further, the cavity die and the core die above and below the parting line are combined and polished to be connected smoothly.

Further, an ejection mechanism is arranged in the mold core mold and used for ejecting and demolding.

And further, a slide block is assembled between the third core die and the cavity die and is used for forming the right appearance surface of the product and demoulding.

According to the characteristics of automobile inner handle ornament products, the first mold core mold is disassembled into the third mold core mold, after the part of the mold core mold with the ornament appearance surface is assembled with the cavity mold through the frustum and the positioning column, the parting line and the appearance polished surface of the parting line are visible, so that the merging and polishing operation of the mold cavity and the mold core mold becomes possible, the defects that the dimension deviation of the appearance polished surface or the acute angle of the parting line becomes blunt (round) under the independent polishing of the two molds are effectively overcome, and the visual effect without touch feeling of the parting line of the ornament appearance surface is realized.

The mould core structure convenient for polishing utilizes the structure that the first mould core is disassembled into the third mould core, and the partial mould core with the ornament appearance surface is assembled with the mould cavity through the frustum and the positioning column, so that the appearance polishing surface and the parting line are visible, and the integral polishing operation is convenient.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings

As shown in fig. 1 and 2, a mold core structure convenient for polishing includes a cavity mold 1 and a core mold 2, the cavity mold 1 is disposed in a front mold plate, the core mold is disposed in a rear mold plate, the core mold includes three parts, and is formed by combining and assembling a core mold 2, a core mold two 3, and a core mold three 4, the core mold 2 and the cavity mold 1 form an appearance surface of a product, an assembled parting line 7 is located on the appearance surface of the product, and the core mold two 3 and the core mold three 4 are assembled to form an internal structure of the product. The first core die 2 and the cavity die 1 are assembled through a frustum and a positioning column. Here in a manner similar to that of the core and cavity molds of a conventional mold. Because the first core die 2 and the first cavity die 1 are installed firstly and the core die is divided into three parts, the parting line can be seen, the upper cavity die and the lower cavity die and the first core die can be combined and polished, and the phenomenon of unevenness caused by respective polishing can not occur. After polishing, the mold is ejected out according to the general mold core assembling method. And meanwhile, a sliding block is assembled between the third core die and the cavity die and is used for forming the right appearance surface of a product and demoulding.

The using method of the novel mold core structure is similar to that of a common mold core during use, and is different from the assembly of the common mold core in that the partial mold core with the ornament appearance surface is assembled firstly, the merging and polishing treatment is carried out, and then other mold cores without the ornament appearance surface are assembled. Therefore, the parting surface can be visualized, and other applications are more convenient and flexible.
