Description

Technical Field

[0001] The utility model relates to the technical field of molds, and more particularly to an inverted speaker installation structure. Background Art

[0002] Mold (mújù) refers to various molds and tools used in industrial production to obtain the desired products by methods such as injection molding, blow molding, extrusion, die-casting or forging, smelting, and stamping. In short, a mold is a tool used to make molded objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the object's shape by changing the physical state of the molded material.

[0003] Currently, the shell of speaker products is relatively complex, with many holes, columns, and slopes. The shell of the speaker may also have hollow parts. The columns, small holes, sinks and the vertical edges of the sinks are particularly prone to demolding and cracking. Utility Model Content

[0004] The utility model aims to provide an inverted speaker installation structure and a mold for the inverted speaker installation structure with a complex structure and convenient demoulding.

[0005] The above technical purpose of the present invention is achieved through the following technical solutions: an inverted speaker installation structure, including a male template and a female template.

[0006] The male plate is a core-pulling plate, and the die-jointing surface of the male plate is provided with two long strip receiving grooves symmetrically arranged with the injection flow channel, and a strip-shaped forming block is provided in each of the two long strip receiving grooves. The strip-shaped forming blocks are at least partially protruded from the die-jointing surface of the male plate and at least partially inserted into the female plate;

[0007] The mother template is a base plate, and a strip-shaped molding groove corresponding to the accommodating groove is opened on the mold surface of the mother template, and a boss molding block is arranged in the strip-shaped molding groove;

[0008] After the male template and the female template are molded together, the strip-shaped forming block is at least partially inserted into the strip-shaped forming groove to form a forming cavity together with the strip-shaped forming groove and the boss forming block.

[0009] By setting up the long strip receiving groove to divide the male template into long strip forming blocks for the second time, it is possible to avoid damage to the rod when demolding with great force. The setting of the long strip forming blocks can also make it possible to observe the finished product more accurately during demolding, thereby preventing damage to the finished product during demolding.

[0010] The utility model is further configured as follows: a demolding notch is provided at one end of the strip forming block and on a side close to the male template; a first demolding circular hole and a plurality of second demolding circular holes provided in a circular array around the demolding circular hole are provided at one end of the forming cavity away from the demolding notch, and a demolding square hole is provided at a point away from the demolding notch and away from the first demolding circular hole.

[0011] By setting the demoulding notch, the cylindrical forming block can be effectively embedded therein, and the circular hole is partially disengaged in advance during demoulding so that air can enter the interior, thereby achieving a smoother demoulding effect.

[0012] The utility model is further configured as follows: the demoulding notch is a notch open on both sides, and a cylindrical forming block is embedded in the demoulding notch.

[0013] The open slot arrangement makes it easier to take out the cylindrical forming block.

[0014] The utility model is further configured as follows: a demoulding edge is provided on the top edge of the cylindrical forming block, and after the mold is closed, the top surface of the demoulding edge is flush with the top surface of the strip forming block.

[0015] By making the top surface flush after mold closing, the cover plate or the pressure block, the spacer and other external structures can be effectively brought into contact with each other as expected to achieve a compacting effect.

[0016] The utility model is further configured as follows: a circular hole forming block is provided in the first demoulding circular hole.

[0017] The split arrangement of the circular hole forming block allows demoulding here first, facilitating the subsequent demoulding process.

[0018] The utility model is further configured as follows: a plate-shaped forming block is provided between the second demolding circular hole and the strip-shaped forming groove; a corresponding circular hole is opened in the plate-shaped forming block corresponding to the second demolding circular hole; and a circular hole forming block is embedded in the second demolding circular hole.

[0019] The setting of plate-shaped forming blocks can effectively form steps or sinking platforms. This product has a sinking platform and vertical edges are set on both sides of the sinking platform. Setting plate-shaped forming blocks can solve the problem of vertical edges being easily broken, or the situation of vertical plate cracks is reduced.

[0020] In summary, the utility model has the following beneficial effects: by setting up the long strip accommodating groove to divide the male template into long strip forming blocks for the second time, it is possible to avoid damage to the rod when demolding with great force; and by setting up the long strip forming blocks, the condition of the finished product can be observed more accurately during demolding, thereby preventing damage to the finished product during demolding.
