Description

Technical Field

[0001] The utility model relates to the technical field of new energy vehicles, in particular to an injection mold of an electronic water pump housing for new energy vehicles. Background Art

[0002] Electronic water pumps are usually used as the main component and power source of the cooling system of new energy vehicles. They play an irreplaceable role in ensuring that the heat-generating components in new energy vehicles operate at normal temperatures.

[0003] like Figure 1 The housing 01 of the electronic water pump shown in the figure is provided with three Figure 2 The pin terminal 02 shown. When the housing 01 of the electronic water pump is formed by injection molding, the pin terminal 02 must first be inserted into the insertion hole on the mold insert in the injection mold. However, since the pin terminal 02 is small in size and has a special-shaped structure, and the space in the injection mold is relatively narrow, it is not easy to insert the pin terminal 02, and it is easy to fall between the mold and the slider in the injection mold during the insertion process, affecting the injection molding efficiency. Due to the high temperature of the injection mold, it is difficult for operators to operate when placing the pin terminal 02 into the injection mold, and they are easy to be scalded, and the injection molding safety is low. In addition, when inserting the pin into the insertion hole on the mold insert in the injection mold, if the pin terminal 02 is slightly misaligned, a pin pressing problem will occur during mold closing, and even damage to the injection mold will occur. Utility Model Content

[0004] In order to improve the injection molding efficiency, the utility model proposes an injection mold for an electronic water pump housing, which includes a sliding mechanism and a connecting piece, wherein the connecting piece includes a connecting block and a positioning plate, the positioning end of the connecting block is connected to the sliding mechanism, and the connecting block is provided with a limiting groove toward the assembly end of the injection mold groove; the positioning plate is installed in the limiting groove, and a positioning groove is provided on the top surface or the bottom surface of the positioning plate, and when a pin terminal is inserted into the positioning groove, the positioning groove cooperates with the groove wall of the limiting groove to clamp the pin terminal; during the injection molding process, the connecting piece is driven by the sliding mechanism to reciprocate, and the pin terminal is inserted into the terminal groove on the mold core insert.

[0005] When an electronic water pump housing is injection-molded using the injection mold of the present utility model, before mold clamping, a sliding mechanism can be used to push a connecting member towards the injection mold cavity, so that the pin terminals inserted in the positioning grooves reach the positions corresponding to the terminal grooves on the mold core insert, and thus the pin terminals are inserted into the terminal grooves on the mold core insert during mold clamping. In this way, when the mold is in the open state, the operator only needs to insert the pin terminals into the positioning grooves on the connecting member far from the mold core. It is not easy for the operator to drop the pin terminals between the mold core and the slider during the insertion process, nor is it easy to be scalded by the injection mold. Thus, when an electronic water pump housing is injection-molded using the injection mold of the present utility model, the injection efficiency and injection safety can be effectively improved.

[0006] Preferably, a limiting stop block is arranged in the positioning groove. In this way, when the pin terminals are inserted into the positioning grooves, the insertion depth of the pin terminals can be limited by the limiting stop block to meet the insertion requirements of pin terminals of different specifications.

[0007] Preferably, positioning holes are arranged at corresponding positions on the connecting block and the positioning plate, and positioning bolts are installed in the positioning holes. In this way, by using the positioning bolts to fix the positioning plate in the limiting groove on the connecting block, the positioning plate can be prevented from shaking in the limiting groove, which affects the insertion of the pin terminals, and the fixing is simple and convenient. Further, the positioning holes are close to the positioning end of the connecting block. In this way, the positioning holes can be as far away from the assembly end of the connecting block as possible, so that the bottom of the positioning groove can be as far away from the assembly end of the connecting block as possible, that is, the depth of the positioning groove can be deeper to meet the insertion requirements of pin terminals of different specifications.

[0008] Preferably, a connecting convex is arranged at the connecting end of the connecting block, and a connecting groove is arranged on the sliding mechanism, and the connecting convex is clamped in the connecting groove. In this way, the connecting block in the connecting member is clamped with the connecting groove on the sliding mechanism through the connecting convex, and the connection is simple and convenient. Further, the connecting groove is located on the connecting slider in the sliding mechanism, and the connecting groove penetrates the bottom surface and the top surface of the connecting slider. In this way, when disassembling and assembling the connecting member, the disassembling and assembling personnel only need to slide the connecting member along the connecting groove, and the disassembly and assembly are simple, convenient and fast.

[0009] Preferably, a support plate is provided at the bottom end of the connecting card slot, and the support plate is connected to the connecting slider through a connecting bolt. In this way, setting a support plate at the bottom end of the connecting card slot can prevent the connecting member from falling off from the bottom end of the connecting card slot and separating from the sliding mechanism, thus affecting the use. Further, the support plate and the connecting block are fixedly connected through a fastening bolt. In this way, by fixedly connecting the support plate and the connecting block in the connecting member through the fastening bolt, it can prevent the connecting member from shaking and misaligning during the injection molding process, which affects the insertion of the pin terminal, and improves the injection molding efficiency of the injection mold for the electronic water pump housing of the present utility model.

[0019] Next, in combination with Figures 3 to 9 , the injection mold for the electronic water pump housing of the present utility model will be described in detail.

[0020] As shown in Figures 3 to 6As shown in the figure, the injection mold for the electronic water pump housing of the present utility model includes a sliding mechanism 1 and a connecting member 2. The connecting member 2 includes a connecting block 21 and a positioning plate 22. The positioning end of the connecting block 21 is connected to the sliding mechanism 1, and a limiting groove (not shown in the figure) is provided at the assembling end of the connecting block 21 facing the injection mold cavity 3; the positioning plate 22 is installed in the limiting groove, and a positioning groove 221 is provided on the top surface or the bottom surface of the positioning plate 22. When the pin terminal 3 is inserted into the positioning groove 221, the positioning groove 221 and the groove wall of the limiting groove cooperate to clamp the pin terminal 3; during the injection process, the connecting member 2 makes a reciprocating motion driven by the sliding mechanism 1, and inserts the pin terminal 3 into the terminal groove (not shown in the figure) on the mold insert 4. Preferably, a limiting block 23 is provided in the positioning groove 221. In this way, when the pin terminal is inserted into the positioning groove, the insertion depth of the pin terminal can be limited by the limiting block to meet the insertion requirements of different specifications of pin terminals. Preferably, positioning holes (not shown in the figure) are provided at corresponding positions on the connecting block 21 and the positioning plate 22, and a positioning bolt 24 is installed in the positioning holes. In this way, the positioning plate 22 is fixed in the limiting groove on the connecting block 21 by the positioning bolt 24, which can prevent the positioning plate 22 from shaking in the limiting groove and affecting the insertion of the pin terminal 3, and the fixing is simple and convenient. Preferably, the positioning holes are close to the positioning end of the connecting block 21. In this way, the positioning holes can be as far away from the assembling end of the connecting block 21 as possible, so that the bottom of the positioning groove 221 can be as far away from the assembling end of the connecting block 21 as possible, that is, the depth of the positioning groove 221 can be deeper to meet the insertion requirements of different specifications of pin terminals 3. In specific implementation, the number of positioning grooves 221 provided on the positioning plate 22 can be adjusted according to needs. For example, 3 positioning grooves 221 are provided on the bottom surface of the positioning plate 22.

[0021] As Figures 3 to 9As shown in the figure, a connection card slot 111 is provided on the sliding mechanism 1, and a connection card projection 212 is provided at the connection end of the connection block 21. The connection card projection 212 is clamped in the connection card slot 111. In this way, the connection block 21 in the connecting member 2 is clamped to the connection card slot 111 on the sliding mechanism 1 through the connection card projection 212, and the connection is simple and convenient. Preferably, the connection card slot 111 is located on the connection slider 11 in the sliding mechanism 1, and the connection card slot 111 penetrates through the bottom surface and the top surface of the connection slider 11. In this way, when disassembling and assembling the connecting member, the disassembling and assembling personnel only need to slide the connecting member 2 along the connection card slot 111, and the disassembly and assembly are simple, convenient and fast. Preferably, a support plate 12 is provided at the bottom end of the connection card slot 111, and the support plate 12 is connected to the connection slider 11 through a connection bolt (not shown in the figure). In this way, by providing the support plate 12 at the bottom end of the connection card slot 111, it can be avoided that the connecting member 2 falls off from the bottom end of the connection card slot 111 and separates from the sliding mechanism 1, affecting the use. Preferably, the support plate 12 and the connection block 21 are connected and fixed through a fastening bolt (not shown in the figure). In this way, by connecting and fixing the support plate 12 and the connection block 21 in the connecting member 2 through the fastening bolt, it can be avoided that the connecting member 2 shakes and is misaligned during the injection molding process, affecting the insertion of the pin terminal 3, and improving the injection molding efficiency of the injection mold for the electronic water pump housing of the present utility model.

[0022] When the injection mold for the electronic water pump housing of the present utility model is used to inject and form the electronic water pump housing, before the mold is closed, the sliding mechanism can be used to push the connecting member towards the injection mold cavity, so that the pin terminal inserted in the positioning slot reaches the position corresponding to the terminal slot on the mold core insert, so that the pin terminal can be inserted into the terminal slot on the mold core insert when the mold is closed. In this way, the operator only needs to insert the pin terminal into the positioning slot on the connecting member far from the mold core in the open mold state. It is neither easy for the operator to drop the pin terminal between the mold core and the slider during the insertion process, nor easy to be scalded by the injection mold. Thus, it can be seen that using the injection mold for the electronic water pump housing of the present utility model to inject and form the electronic water pump housing can effectively improve the injection molding efficiency and injection molding safety.
