Description
Technical Field
The utility model relates to the technical field of injection molding, in particular to a drainage sheet for injection molding.
Background
In the prior art, the product material is injected into a mold cavity after passing through a drainage sheet in the injection molding process. The existing drainage sheet mainly comprises a horn-shaped drainage sheet and a linear drainage sheet, and when the drainage sheet is adopted for injection molding, the drainage sheet does not play any role in buffering injection molding fluid, so that water filaments are produced on the surface of an injection molded product, and the quality of the injection molded product cannot meet the requirements.
Therefore, there is a need to design a drainage sheet for injection molding to solve the above problems.
Disclosure of utility model
The utility model aims at solving the problem that the injection molding product in the prior art shows water filaments, and provides a drainage sheet for injection molding.
The technical scheme of the utility model is as follows: a drainage sheet for injection molding comprises a drainage sheet body; the drainage sheet body is provided with an injection molding channel; the injection molding channel comprises a first channel and a second channel communicated with the first channel through a connecting channel; an injection molding inlet communicated with the first channel is arranged in the middle of one side of the first channel; an outlet channel communicated with the second channel is arranged in the middle of one side of the second channel.
And a U-shaped injection molding channel is formed among the first channel, the connecting channel and the second channel.
The shape of the drainage sheet body is consistent with that of the injection molding channel.
The drainage sheet body is formed by injection molding.
The length of the second channel is longer than the length of the first channel.
The connecting channel is arc-shaped.
The drainage sheet body is made of transparent materials.
By adopting the technical scheme, the utility model has the following beneficial effects: the injection molding channel on the drainage sheet body comprises a first channel and a second channel communicated with the first channel through the connecting channel, the injection molding inlet and the injection molding outlet are respectively arranged in the middle of the first channel and the second channel, and during injection molding, injection molding materials with water filaments can stay at the end parts of the first channel and the second channel and cannot flow out of the outlet channel in the middle of the second channel, so that the problem that water filaments exist on the surface of an injection molding product is solved.
Drawings
In order that the utility model may be more readily understood, a more particular description of the utility model will be rendered by reference to specific embodiments that are illustrated in the appended drawings.
Fig. 1 is a schematic structural view of the present utility model.
The reference numerals in the drawings are:
The drainage piece comprises a drainage piece body 1, an injection molding channel 2, a first channel 2-1, a connecting channel 2-2, a second channel 2-3, an injection molding inlet 2-4 and an outlet channel 2-5.
Detailed Description
Example 1
Referring to fig. 1, a drainage sheet for injection molding of the present embodiment includes a drainage sheet body 1; the drainage sheet body 1 is provided with an injection molding channel 2; the injection molding channel 2 comprises a first channel 2-1 and a second channel 2-3 communicated with the first channel 2-1 through a connecting channel 2-2; an injection molding inlet 2-4 communicated with the first channel 2-1 is arranged in the middle of one side of the first channel 2-1; the middle part of one side of the second channel 2-3 is provided with an outlet channel 2-5 communicated with the second channel 2-3.
Further, the first channel 2-1, the connecting channel 2-2 and the second channel 2-3 form a U-shaped injection molding channel 2, which is the optimal embodiment.
Furthermore, the shape of the drainage sheet body 1 is consistent with that of the injection molding channel 2, so that the occupied space of the drainage sheet can be reduced, and the preparation cost is reduced.
Furthermore, the drainage sheet body 1 is formed by injection molding, so that the processing is more convenient.
Further, the length of the second channel 2-3 is longer than that of the first channel 2-1, so that the flowing time of the injection molding fluid can be prolonged, and the injection molding material with water filaments can be further convenient to stay at the end part of the second channel 2-3.
Furthermore, the connecting channel 2-2 is arc-shaped, can play a certain buffering role on injection molding fluid, reduces the flow velocity of the injection molding fluid, and is further convenient for the injection molding material with water filaments to stay at the end part of the second channel 2-3.
Preferably, the drainage sheet body 1 is made of transparent material.
The injection molding channel 2 on the drainage sheet body 1 of the embodiment comprises a first channel 2-1 and a second channel 2-3 communicated with the first channel 2-1 through a connecting channel 2-2, and an injection molding inlet 2-4 and an injection molding outlet 2-5 are respectively arranged in the middle of the first channel 2-1 and the second channel 2-3, and when injection molding, injection molding materials with water filaments can stay at the end parts of the first channel 2-1 and the second channel 2-3 and cannot flow out of the outlet channel 2-5 in the middle of the second channel 2-3, so that the problem that water filaments exist on the surface of an injection molding product is solved.
While the foregoing is directed to embodiments of the present utility model, other and further details of the utility model may be had by the present utility model, it should be understood that the foregoing description is merely illustrative of the present utility model and that no limitations are intended to the scope of the utility model, except insofar as modifications, equivalents, improvements or modifications are within the spirit and principles of the utility model.
