[0037] Embodiment 1

[0038] According to the current development strategy of energy saving and consumption reduction, without affecting the mold production efficiency and product quality, the original internal gear mold structure of the injection molding workshop is optimized, the number of glue feed channels is adjusted, and the number of glue feed ports is adjusted to save raw materials and reduce production costs. The existing technology is prone to erroneous connection or blocking of the branch channel when adjusting the flow channel control block, which is cumbersome to operate and cannot quickly adjust the glue feed channel. Therefore, it is necessary to develop a structure that can quickly adjust the glue feed channel and improve the original mold structure to achieve the purpose of reducing production costs.

[0039] In view of the above problems, an embodiment of the present application provides a structure for adjusting a glue inlet flow channel, which can effectively reduce the loss of raw materials and save production costs.

[0040] The technical solution of the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0041] See also Figures 1 to 4 , the first embodiment of the structure for adjusting the glue inlet flow channel shown in the embodiment of the present application includes:

[0042] A fixed mold insert 1 and a fixed mold plate 2, wherein the fixed mold plate 2 is provided with M initial glue inlet channels 21 and an insert groove 22. In an embodiment of the present application, the fixed mold plate 2 can be obtained by modifying an original fixed mold plate with a 9-point glue inlet structure, and processing is performed at the pouring port of the original fixed mold plate to form an insert groove 22 on the original fixed mold plate to obtain the fixed mold plate 2.

[0043] It is understandable that in actual applications, there are various ways to set the number of glue inlets on the original fixed mold plate. A fixed mold plate with other numbers of glue inlets can be used for renovation, or a new fixed mold plate can be designed for actual production. It depends on the actual application situation and is not the only limitation here.

[0044] In an embodiment of the present application, N glue feed channels 11 are provided on the fixed mold insert 1. When the fixed mold insert 1 is installed in the insert groove 22, the N glue feed channels 11 are connected with the corresponding N initial glue feed channels 21 among the M initial glue feed channels 21, N is an integer greater than zero, and M is greater than N, thereby realizing the function of adjusting the glue feed channels.

[0045] From the above embodiment 1, the following beneficial effects can be seen:

[0046] By installing the fixed mold insert in the insert groove set in the fixed mold plate, the N glue inlet channels provided on the fixed mold insert are connected with the corresponding N initial glue inlet channels among the original M initial glue inlet channels on the fixed mold plate, so that the raw materials can flow along the N glue inlet channels to the corresponding N initial glue inlet channels and enter the corresponding glue inlet ports for injection molding, thereby avoiding the waste of raw materials caused by the raw materials flowing into unnecessary glue inlets, which can effectively reduce the loss of raw materials and save production costs.

[0047] Embodiment 2

[0048] For ease of understanding, an embodiment of adjusting the structure of the glue feed channel is provided below for illustration. In actual applications, a blocking groove is also provided on the fixed mold insert to serve as a flow interception and blocking function. The blocking grooves are arranged alternately with the glue feed channels to form an axial symmetry between the glue feed channels. While saving raw materials, it can achieve a balanced casting effect and ensure production quality.

[0049] See also Figure 4 and Figure 5 The second embodiment of the structure for adjusting the glue inlet channel shown in the embodiment of the present application includes:

[0050] The fixed mold insert 1 is also provided with MN blocking grooves 12, and a blocking block is provided in the blocking groove 12. The blocking block is embedded in the blocking groove 12, and its size matches the size of the blocking groove 12 to play a throttling and blocking role. The material of the blocking block can be iron or copper, etc., which has a higher melting point than the injection molding raw material. In actual applications, the material of the blocking block needs to be determined according to the actual application situation, and it is not the only limitation here.

[0051] The blocking grooves 12 and the glue feed channels 11 are arranged alternately, and are circumferentially distributed at the main glue injection port 13 of the fixed mold insert 1, and are connected to the main glue injection port 13. It can be understood that the total number of the blocking grooves 12 and the glue feed channels 11 on the fixed mold insert 1 is consistent with the number of the original initial glue feed channels on the fixed mold plate, and they correspond one to one. When it is necessary to restore to the M initial glue feed channels for pouring, it can be achieved by removing the blocking block or removing the fixed mold insert 1 from the insert groove 22, thereby increasing the application range of the original fixed mold plate, saving production materials, and reducing production costs.

[0052] In order to achieve a balanced pouring effect, N glue inlet channels 11 are symmetrically distributed with the symmetry axis of the fixed mold insert 1 in the length direction as the symmetry axis of the glue inlet channels. In the embodiment of the present application, N is an odd number. When pouring and producing an internal gear disc product, the value of N can be 5. It can be understood that in actual applications, the value of N is diverse and needs to be determined according to the actual application situation, and is not limited here.

[0053] like Figure 5 As shown, the N glue feed channels 11 include: an axial glue feed channel 111, a first symmetrical channel group 112 and a second symmetrical channel group 113, wherein the axial glue feed channel is arranged at the symmetry axis of the glue feed channel; the angle between any one of the glue feed channels in the first symmetrical channel group 112 and the axial glue feed channel 111 is j is an integer greater than or equal to 1; the angle between any one of the glue feed channels in the second symmetrical flow channel group 113 and the axial glue feed channel 111 is The angle between the glue feeding channels in the second symmetrical channel group 113 is

[0054] Assume that the current casting production of the internal gear disc product adopts the fixed mold plate 2 obtained by modifying the original fixed mold plate with a 9-point glue inlet structure, which means that the number of initial glue inlet channels 21 is 9. In the current case, the fixed mold insert 1 has 5 glue inlet channels 11 and 4 blocking grooves 12, and the 4 blocking grooves 12 are provided with blocking blocks for intercepting and blocking. Then, the value of j corresponding to the first symmetrical flow channel group 112 is 1, that is, the angle between any glue inlet channel in the first symmetrical flow channel group 112 and the axial glue inlet channel 111 is 80°; the angle between any glue inlet channel in the second symmetrical flow channel group 113 and the axial glue inlet 111 is 160°; the angle between the glue inlet channels in the second symmetrical flow channel group 113 is 40°, that is, the angle between adjacent initial glue inlet channels 21.

[0055] It is understandable that the above hypothetical description is only exemplary to facilitate a better understanding of the technical solution of the present application. In actual applications, the number of initial glue feed channels 21 and glue feed channels 11 needs to be determined according to actual application conditions to achieve the effect of adjusting the glue feed channels. This is not a sole limitation.

[0056] From the above-mentioned embodiment 2, the following beneficial effects can be seen:

[0057] By arranging alternately and circumferentially distributed glue feed channels and blocking grooves on the fixed mold insert, unnecessary glue feed channels are intercepted and blocked to avoid the waste of raw materials caused by the raw materials flowing into unnecessary glue feed ports, which can effectively reduce the loss of raw materials and save production costs; the glue feed channels are axially symmetrical, which can achieve a balanced casting effect while saving raw materials and ensuring production quality.

[0058] Embodiment 3

[0059] For ease of understanding, an embodiment of adjusting the structure of the glue inlet flow channel is provided below for illustration. In actual applications, the clearance between the fixed mold insert and the insert groove is matched, which is beneficial to the combined molding of the injection molding machine and the mold during the pouring process, and improves the stability of the injection molding machine during the pouring process.

[0060] See also Figure 1 , Figure 4 and Figure 5 The third embodiment of the structure for adjusting the glue inlet channel shown in the embodiment of the present application includes:

[0061] The insert size of the fixed mold insert 1 is consistent with the inner size of the insert groove 22, so that the fixed mold insert 1 and the insert groove 22 are clearance matched. In the embodiment of the present application, the material of the fixed mold insert 1 can be 738H fine material. It can be understood that in actual application, the material for making the fixed mold insert 1 needs to be determined according to the actual application situation, and it is not limited here. The size of the fixed mold insert 1 includes but is not limited to the length, width and height, wherein the length can be selected from a value between 75 mm and 85 mm, preferably 80 mm; the width can be selected from a value between 40 mm and 48 mm, preferably 44 mm; the height can be selected from a value between 10 mm and 20 mm, preferably 15 mm. Correspondingly, the inner size of the insert groove 22 is also the same as that of the fixed mold insert 1, so that the fixed mold insert 1 and the insert groove 22 are clearance matched, and the clearance range of the clearance match between the two can be between 0.01 mm and 0.02 mm. Among them, clearance fit refers to a fit with clearance, including a fit with a minimum clearance equal to zero, that is, the actual size of the hole or groove is always greater than or equal to the actual size of the shaft or other column, so that the shaft or other column can move just inside the hole or groove.

[0062] During the pouring process, the pouring arm of the injection molding machine is combined with the N glue inlet channels 11 on the fixed mold insert 1 respectively, and recombined into a sprue cavity with N glue inlets. Assuming that the value of N is 5 and the number of initial glue inlet channels 21 is 9, the weight of the product's sprue raw material will be reduced from 118g corresponding to the original 9 glue inlets to 68g corresponding to the current 5 glue inlets.

[0063] It is understandable that in actual applications, different numbers of glue inlets will correspond to different weights of sprue raw materials, and the actual weight of sprue raw materials needs to be determined based on actual application conditions. The above exemplary data is only for a better understanding of the solution, but it is certain that after adjusting the glue feed channel to prevent raw materials from entering unnecessary glue inlets, the number of glue inlets is reduced, thereby reducing the use of raw materials, and the weight of sprue raw materials is bound to be reduced.

[0064] In order to fix the fixed mold insert 1 in the insert groove 22 and improve the stability during the pouring process, in the embodiment of the present application, a mounting screw hole 221 is provided in the insert groove 22, and a fixing through hole 14 is provided on the fixed mold insert 1. When the fixed mold insert 1 is installed in the insert groove 22, the fixing screw 15 passes through the fixing through hole 14 and cooperates with the mounting screw hole 221 to fix the fixed mold insert 1, wherein the fixing screw 15 can be a hexagon socket screw. Preferably, the hexagon socket screw can be an M5 type hexagon socket screw, and the number of the hexagon socket screws is set to two.

[0065] It is understandable that there are various implementation forms and setting numbers of the fixing screws 15. In practical applications, the specific form and specific setting number of the fixing screws 15 need to be determined according to the actual application situation, and no sole limitation is made here.

[0066] From the above embodiment 3, the following beneficial effects can be seen:

[0067] By setting the size of the fixed mold insert and the inner size of the insert groove to be the same, the fixed mold insert and the insert groove can be clearance-matched, which is beneficial to the combination of the injection molding machine and the mold during the pouring process. The fixed mold insert is fixed in the insert groove by the cooperation of the fixing screws, the fixing through holes and the mounting screw holes, thereby improving the stability of the injection molding machine during the pouring process.
