Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Referring to fig. 1, an injection molding structure for producing injection molded parts is disclosed in an embodiment of the present invention, the injection molding structure comprises a main body consisting of a first portion 11, a second portion 12 and a third portion 13, wherein the first portion 11 and the third portion 13 are respectively fixed on the top surface and the bottom surface of the second portion 12, for the sake of clarity of description, the third portion 13 is defined below, the second portion 12 is defined in the middle, and the first portion 11 is defined above, i.e., the first portion 11, the second portion 12 and the third portion 13 are sequentially arranged from top to bottom.
The first part 11, the second part 12 and the third part 13 are integrally formed, namely the three parts are processed by using the same material and naturally connected together after being processed. In the top-down direction, the cross-sectional area and the cross-sectional shape of the first portion 11 and the third portion 13 remain the same, and the cross-sectional shape of the second portion 12 remains the same, but the cross-sectional area tends to decrease, i.e., the exposed side of the second portion 12 is inclined.
Referring to fig. 3 and 4, the mold cavity 14 is a glue site formed on the third portion 13, and during the injection process, the material flows into the mold cavity 14 and is naturally formed after cooling. The mold cavity 14 is mainly composed of a first cavity 141 and a second cavity 142, both of which are communicated with the bottom surface of the third portion 13, and both ends of which are communicated with the side surfaces of the adjacent third portion 13, so that the first cavity 141 and the second cavity 142 can divide the third portion 13 into a plurality of parts, and after the injection molding is completed, a lattice can be formed inside the final product.
In another embodiment of the present invention, the number of the first cavities 141 and the second cavities 142 is plural, so that a plurality of cells can be formed inside the product. In still another embodiment of the present invention, the first cavity 141 and the second cavity 142 are perpendicular to each other, so that a rectangular lattice can be formed inside the final product.
In an embodiment of the present invention, the widths of the first cavity 141 and the second cavity 142 in the direction close to the second portion 12 tend to decrease, so that the resistance during the demolding process can be reduced, and the demolding difficulty can be reduced.
Referring to fig. 1 and 2, the first portion 11, the second portion 12, and the third portion 13 are further provided with positioning holes 15, and both ends of the positioning holes 15 communicate with the top surface of the first portion 11 and the bottom surface of the third portion 13, respectively. When the front die core and the rear die core are installed, the front die core and the rear die core can be fixedly installed through the positioning columns or the non-tail screws.
In one embodiment of the invention, the height of the connection between the mould cavity 14 and the side of the third portion 13 is less than the height of the third portion 13, the limitation being mainly to avoid material flowing out of the gap during injection moulding. After the front mold core and the rear mold core are attached, the first part 11, the second part 12 and the third part 13 are wrapped in cavities in the front mold core and the rear mold core, at the moment, the side surface of the second part 12 is attached to the front mold core or the rear mold core, and when the height of the communication position of the mold cavity 14 and the side surface of the third part 13 is smaller than that of the third part 13, a section of protection can be formed between the attachment position and the communication position, so that raw materials cannot flow into the attachment position of the side surface of the second part 12 and the front mold core or the rear mold core.
Referring to fig. 5 and 6, in an embodiment of the present invention, the first portion 11 is provided with a blind positioning hole 21, an upper end of the blind positioning hole 21 is communicated with the top surface of the first portion 11, and a lower end of the blind positioning hole 21 penetrates through the second portion 12 and then extends into the third portion 13. The positioning blind hole 21 is used for providing space for the positioning column, so that the positioning column can be smoothly inserted into the third part 13, and the function of improving the strength of the third part 13 is achieved. Because the first portion 11, the second portion 12 and the third portion 13 are made of the same material, in order to reduce the processing difficulty, for a part with a complicated structure, the strength of the material is properly reduced instead of reducing the processing difficulty, but the third portion 13 is provided with a plurality of first cavities 141 and second cavities 142, which undoubtedly reduces the strength of the third portion 13, because after the material with high temperature and high pressure is injected into the first cavities 141 and the second cavities 142, a huge pressure is applied to the side surfaces of the first cavities 141 and the second cavities 142, and the distribution of the pressure is not uniform, so that the widths of the first cavities 141 and the second cavities 142 are changed, the thickness of the final product is inconsistent, and the final product cannot be demolded even seriously. Consequently, increased location blind hole 21, in the in-process reference column of moulding plastics can disect insertion location blind hole 21 like this, the simple structure of reference column can use high strength material to process, can effectively guarantee the product precision like this.
In an embodiment of the present invention, the bottom surface of the blind positioning hole 21 is a conical surface, so that a conical protrusion is formed on the corresponding positioning column, and after the positioning column is inserted into the blind positioning hole 21, the conical protrusion will abut against the conical bottom surface of the blind positioning hole, which can improve the connection precision between the blind positioning hole and the positioning column, and reduce the probability of the third part 13 moving during the injection molding process. Because in the actual production process, in order to ensure that the positioning column can be smoothly inserted into the positioning blind hole 21, the diameter of the positioning column needs to be smaller than the inner diameter of the positioning blind hole 21, which may cause the third portion 13 in the injection molding process to be displaced after receiving a thrust force, and especially, the displacement is uncertain, which may easily cause the thickness of the final product to be uneven. When the bottom surface of the positioning blind hole 21 is changed into a conical surface, the bottom surface can be offset with the thrust force applied to the third part 13 in the horizontal direction, and the probability of displacement is reduced.
Referring back to fig. 4, in an embodiment of the present invention, the first cavity 141 and the second cavity 142 divide the bottom surface of the third portion 13 into a plurality of regions, which are generally arranged in a matrix of MxN, where M and N are natural numbers, and the strength of a portion of the third portion 13 corresponding to each region is reduced, and in order to achieve effective reinforcement, the number of the blind positioning holes 21 needs to be the same as that of the regions, and the lower end of each blind positioning hole 21 can correspond to a region uniquely determined therewith, so that a positioning column can be ensured in each region.
Referring to fig. 2 and 5, in an embodiment of the present invention, the top surface of the first portion 11 is provided with a plurality of connecting slots 23, and two ends of each connecting slot 23 are respectively communicated with the adjacent blind positioning holes 21. The increase of spread groove 23 can also increase corresponding connecting piece between the adjacent reference column, and these connecting pieces directly block into spread groove 23 in the installation, can play the positioning action, make smooth removal of reference column to the assigned position, and on the other hand, spread groove 23 can play the effect of strengthening the reference column root after with the connecting piece cooperation, reduces this probability of breaking. Since the end of the connecting stud inserted into the blind positioning hole 21 is stressed during the injection molding process, but the moment of its root is the greatest, it is necessary to match the connecting slot 23 with the connecting element to counteract this moment.
Referring to fig. 5 and 6, in another embodiment of the present invention, a sunken groove 22 is added on the top surface of the first portion 11, and the connecting groove 23 and the blind positioning hole 21 are transferred to the bottom surface of the sunken groove 22, because the sunken grooves 22 are small in number and large in area, the connecting groove 23 is easier to process and has higher processing precision, the problem of repeated positioning caused by a plurality of connecting grooves 23 can be avoided, and after the sunken grooves 22 are added, the processing precision of the connecting grooves 23 can be properly reduced, so that the mounting process is easier, and the problem that the connecting element cannot be clamped into the connecting element can be effectively reduced.
The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
