Description

Technical Field

[0001] This invention relates to the field of mold technology, specifically to a molding mold for producing automotive water pump valve cores. Background Technology

[0002] The water pump valve core is a key component in the automotive cooling system, mainly used to control the flow direction and pressure of the coolant.

[0003] The structure of the car water pump valve core is as follows Figure 7 As shown, injection molding is typically used.

[0004] like Figure 7 As shown, there are several cavities around the valve core, so the mold needs to have a matching slider. The existing mold moves the slider by a slant rod, with a compression spring and a limit rod located at both ends of the slider. This allows the slider to remain in the separated position after separating from the slant rod, making it easy to re-fit with the slant rod next time.

[0005] However, during the above process, because the compression spring is distributed close to the cavity of the mold, the high temperature causes the stiffness of the compression spring to decrease. As a result, the compression spring does not provide enough restoring force to the slider after the inclined rod separates from the slider. Consequently, after the slider separates from the inclined rod and comes into contact with the limit rod, it will move the slider away from the limit rod, causing the slider to not stay at the position where it is separated from the inclined rod. At this time, it will also cause a collision when the slider and the inclined rod re-engage.

[0006] Therefore, the applicant has developed a new technical solution in the actual production process to solve the above-mentioned technical problems. Summary of the Invention

[0007] To address the aforementioned technical shortcomings, the present invention aims to provide a molding die for the production of automotive water pump valve cores, which has the advantage of distributing the compression spring away from the mold cavity, facilitating the separation of the slider and the inclined rod, and ensuring that the slider remains in the separated position.

[0008] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0009] This invention provides a molding die for producing automotive water pump valve cores, including a moving mold plate and a fixed mold plate. The moving mold plate is provided with a cavity plate that mates with the valve core. Several sliders are slidably connected to the moving mold plate. Each slider is fitted with a core block that enters the cavity plate, and each slider is provided with an inclined groove. The fixed mold plate is provided with a core plate that mates with the cavity plate. The fixed mold plate is provided with inclined rods that mate with each inclined groove. The invention also includes a limiting mechanism provided on the moving mold plate. When the inclined rods are separated from the sliders, the limiting mechanism is fitted with a positioning rod that enters the inclined groove to position the sliders on the moving mold plate.

[0010] When the mold is closed, the inclined bar is inserted into the inclined groove, causing the inclined groove to be misaligned with the positioning rod, thereby pressing the positioning rod into the limiting mechanism and releasing the limiting of the slider;

[0011] The limiting mechanism includes an installation groove on the moving template. When the inclined rod and the slider are separated, the inclined groove and the installation groove are on the same inclined line, and the positioning rod is slidably connected in the installation groove. The positioning rod is equipped with an elastic element to push the upper part of the positioning rod out of the installation groove and into the inclined groove. When the mold is closed, the inclined rod enters the inclined groove, and one end of the slider still covers the opening of the installation groove.

[0012] By adopting the above technical solution, when the mold is closed, the inclined rod is inserted into the inclined groove, so that one end of each slider enters the cavity plate. At this time, the core block, cavity plate, and core plate form the shape required for the injection molded part. After injection molding is completed, the mold is opened, and each inclined rod gradually moves out of the inclined groove, thereby removing the core block on each slider from the injection molded part, which facilitates the demolding of the subsequent injection molded part. When the inclined rod moves out of the inclined groove, the positioning rod enters the inclined groove, thereby positioning the slider, which is convenient for the inclined rod to enter the inclined groove when the mold is closed again. After the inclined rod enters the inclined groove again, the positioning rod moves out of the inclined groove instantly, releasing the limit on the slider, which is convenient for the inclined rod to drive the slider to move. During the above process, after the slider and the inclined rod separate, due to the setting of the positioning rod, the slider still stays in the separated position, and no compression spring is set near the mold cavity.

[0013] Preferably, it also includes a sprue plate and a fixed mold base located on the side of the fixed mold plate away from the moving mold plate. When the mold is opened, the sprue plate is first separated from the fixed mold plate, then the sprue plate is separated from the fixed mold base, and finally the fixed mold plate and the moving mold plate are separated, which is used to separate the sprue material and the injection molded part and demold them separately.

[0014] Preferably, a receiving component for receiving sprue material is provided between the sprue plate and the fixed template, and a receiving component for receiving injection molded parts is provided between the fixed template and the moving template.

[0015] Preferably, the receiving component one includes a rubber pad layer one located between the sprue plate and the fixed mold plate and distributed at an incline, used to guide the sprue material out of the sprue plate and the fixed mold plate. The two long sides of the rubber pad layer one are provided with rubber pad layers two that are respectively fixed to the lower end face of the sprue plate and the fixed mold plate. When the mold is opened, the sprue plate is separated from the fixed mold base, and the rubber pad layers two are in a vertically distributed state.

[0016] Preferably, the receiving component two has the same structure as the receiving component one.

[0017] Preferably, the receiving component two includes a transfer track located between the fixed template and the moving template. The transfer track is used to guide the injection molded part from the moving template to below the moving template and to adjust the injection molded part from a horizontal position to a vertical position. The transfer track includes two guide rods distributed opposite to each other. The gap between the two guide rods allows a protrusion on one side of the injection molded part to enter. The two guide rods include a vertical section at the upper end and an arc-shaped section connected to the vertical section, which makes the axis of the injection molded part vertically distributed.

[0018] The transmission track is also equipped with a power source, which enables the transmission track to enter between the fixed template and the moving template after the mold is opened.

[0019] Preferably, the power source drives the transmission track to move vertically up and down. The upper outer walls of the two guide rods are provided with horizontal rods extending away from the guide rods. The upper ends of the two horizontal rods are fixedly connected with U-shaped mounting covers, which are fitted over the outside of the injection molded part that has been removed from the driven template.

[0020] Preferably, the two guide rods are equipped with infrared sensors on opposite sides to detect whether the injection molded part has entered the transfer track.

[0021] Preferably, it also includes a transmission belt located on one side of the moving template. The two transmission belts are horizontally distributed and arranged opposite each other. The gap between the two transmission belts allows the protrusions on the injection molded part to enter. The two transmission belts are in contact with the lower end face of the injection molded part. When the power source drives the transmission track to guide the injection molded part between the moving template and the fixed template, the outlet of the transmission track is connected to the inlet of the two transmission belts.

[0022] Preferably, the upper end of the mounting cover is provided with a baffle located directly above the injection molded part.

[0023] The beneficial effects of this invention are as follows: When the mold is closed, the inclined rod is inserted into the inclined groove, so that one end of each slider enters the cavity plate. At this time, the core block, cavity plate, and core plate form the shape required for the injection molded part. After injection molding is completed, the mold is opened, and each inclined rod gradually moves out of the inclined groove, thereby removing the core block on each slider from the injection molded part, which facilitates the demolding of the subsequent injection molded part. When the inclined rod moves out of the inclined groove, the positioning rod enters the inclined groove, thereby positioning the slider, which is convenient for the inclined rod to enter the inclined groove when the mold is closed again. After the inclined rod enters the inclined groove again, the positioning rod moves out of the inclined groove instantly, releasing the limit on the slider, which is convenient for the inclined rod to drive the slider to move. In the above process, after the slider and the inclined rod separate, due to the setting of the positioning rod, the slider still stays in the separated position, and no compression spring is set near the mold cavity.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] A molding die for producing automotive water pump valve cores, such as Figure 1 and Figure 2 The mold includes a moving mold plate 1 and a fixed mold plate 2. The moving mold plate 1 is provided with a cavity plate 11 that cooperates with the valve core 3. Several sliders 12 are slidably connected to the moving mold plate 1. At this time, the moving mold plate 1 is provided with a sliding groove for each slider 12 to slide. The upper end of each slider 12 extends out of the groove opening. The fixed mold plate 2 is also provided with a corresponding groove for the upper end of each slider 12 to enter after the mold is closed. Each slider 12 is equipped with a core block 121 that enters into the cavity plate 11, and each slider 12 is provided with an inclined groove 122. The fixed mold plate 2 is provided with a core plate 21 that cooperates with the cavity plate 11. The fixed mold plate 2 is provided with an inclined rod 22 that cooperates with each inclined groove 122. The end of the inclined rod 22 facing the moving mold plate 1 is inclined away from the center of the mold. At this time, each inclined rod 22 is fixed at the bottom of the corresponding moving groove.

[0036] like Figure 1 and Figure 2 It also includes a limiting mechanism set on the moving template 1. When the inclined rod 22 separates from the slider 12, the limiting mechanism is equipped with a positioning rod 13 that enters the inclined groove 122. At this time, the positioning rod 13 and the inclined rod 22 that has just moved out of the inclined groove 122 are located on the same inclined line, so that the positioning rod 13 positions the slider 12 on the moving template 1.

[0037] like Figure 1 and Figure 2 When the mold is closed, the inclined rod 22 is inserted into the inclined groove 122, causing the inclined groove 122 to be misaligned with the positioning rod 13. Since the positioning rod 13 is also inclined, it is easy to press the positioning rod 13 into the limiting mechanism and release the limiting of the slider 12.

[0038] like Figure 1 and Figure 2When the mold is closed, the inclined rod 22 is inserted into the inclined groove 122, so that one end of each slider 12 enters the cavity plate 11. At this time, the core block 121, the cavity plate 11, and the core plate 21 form the shape required for the injection molded part. After injection molding is completed, the mold is opened, and each inclined rod 22 gradually moves out of the inclined groove 122, thereby removing the core block 121 on each slider 12 from the injection molded part, which facilitates the demolding of the subsequent injection molded part. When the inclined rod 22 moves out of the inclined groove 122, the positioning rod 13 enters the inclined groove 122. This positions the slider 12 so that when the mold closes again, the inclined rod 22 can enter the inclined groove 122. After the inclined rod 22 re-enters the inclined groove 122, the positioning rod 13 instantly moves out of the inclined groove 122, releasing the limit on the slider 12 and allowing the inclined rod 22 to drive the slider 12 to move. During the above process, after the slider 12 separates from the inclined rod 22, the slider 12 remains in the separated position due to the setting of the positioning rod 13, and no compression spring 132 is set near the mold cavity.

[0039] like Figure 1 and Figure 2 The limiting mechanism includes a mounting groove 131 on the moving template 1. When the inclined rod 22 separates from the slider 12, the inclined groove 122 and the mounting groove 131 are on the same inclined line, and the positioning rod 13 is slidably connected in the mounting groove 131. The positioning rod 13 is equipped with an elastic element to push the upper part of the positioning rod 13 out of the mounting groove 131 and into the inclined groove 122. The elastic element includes a compression spring 132 set at the bottom of the mounting groove 131. At this time, the compression spring 132 is distributed away from the mold cavity. The bottom of the mounting groove 131 is provided with a guide rod 133 that passes through and enters the compression spring 132. The positioning rod 13 is provided with a guide groove for the guide rod 133 to slide. The guide rod 133 makes the compression spring 132 in the same position as the positioning rod 13 in the same inclination direction. The guide rod 133 and the positioning rod 13 are coaxially distributed. When the mold is closed, the inclined rod 22 enters the inclined groove 122. One end of the slider 12 still covers the opening of the mounting groove 131, thus restricting the positioning rod 13 within the mounting groove 131. At this time, the compression spring 132 is in a compressed state. When the mold is opened, the inclined rod 22 separates from the inclined groove 122, and the positioning rod 13 moves towards the inclined groove 122 under the action of the compression spring 132 until the upper part of the positioning rod 13 enters the inclined groove 122, thus positioning the slider 12 and keeping it in the position separated from the inclined rod 22. When the mold is closed again, the inclined rod 22 enters the inclined groove 122, which provides a pushing force to the slider 12 towards the center of the mold, thereby causing the slider 12 to squeeze the positioning rod 13 and press the positioning rod 13 into the mounting groove 131. During this process, the positioning rod 13 will only separate from the inclined groove 122 after the inclined rod 22 is inserted into the inclined groove 122, thus stabilizing the position of the positioning rod 13 positioning the slider 12.

[0040] like Figure 1 and Figure 2The end of the positioning rod 13 facing the inclined groove 122 and the end of the inclined rod 22 entering the inclined groove 122 are both designed as arc surfaces.

[0041] like Figure 1 and Figure 2 It also includes a sprue plate 23 and a fixed mold base 24 located on the side of the fixed mold plate 2 opposite to the moving mold plate 1. During mold opening, the sprue plate 23 first separates from the fixed mold plate 2, then the sprue plate 23 separates from the fixed mold base 24, and finally the fixed mold plate 2 and the moving mold plate 1 separate, which is used to separate the sprue material and the injection molded part and demold them separately. The separation process of the sprue plate 23, the fixed mold plate 2 and the moving mold plate 1 is the existing three-plate separation method of the mold, which is prior art and will not be described in detail here. In addition, the moving mold plate 1 is provided with pads 14 on both the left and right ends on the side away from the fixed mold plate 2. The two pads 14 are fixed by the moving mold base 15. The moving mold base 15 has a push plate 16 and a top plate 161 fixed on the push plate 16 between the two pads 14. The top plate 161 is provided with a number of ejector pins 162 that eject the injection molded parts in the cavity plate 11 on the moving mold plate 1. After the mold is opened, the push plate 16 and the top plate 161 move together toward the cavity plate 11, which makes it easier for the ejector pins 162 to eject the injection molded parts in the cavity plate 11.

[0042] like Figure 1 and Figure 2 and Figure 3 The structure of the above mold achieves the purpose of separating the injection molded part and the sprue material. In order to automatically discharge the injection molded part and the sprue material from the mold, a receiving part 1 for receiving the sprue material is provided between the sprue plate 23 and the fixed platen 2, and a receiving part 2 for receiving the injection molded part is provided between the fixed platen 2 and the moving platen 1.

[0043] like Figure 3-6 The receiving component includes an inclined rubber pad 25 located between the sprue plate 23 and the fixed mold plate 2, used to guide the sprue material out of the sprue plate 23 and the fixed mold plate 2. Two rubber pads 251, fixed to the lower end faces of the sprue plate 23 and the fixed mold plate 2 respectively, are provided on the two long sides of the rubber pad 25. The length of the rubber pads 251 is distributed along the length of the lower end faces of the sprue plate 23 and the fixed mold plate 2. When the mold is opened, the sprue plate 23 separates from the fixed mold base 24, and the rubber pads 251 are vertically distributed. The side of the rubber pad 25 with the lower inclination angle extends out of one side of the sprue plate 23, and this side is the outlet of the sprue material. A collection box 252 for collecting the sprue material can be provided below the outlet of the rubber pad 25. The opening of the collection box 252 faces upwards, and its length is distributed along the moving direction of the sprue plate 23.

[0044] like Figure 3-6The setting of the rubber pad 25 does not affect the mold closing of the sprue plate 23 and the fixed mold plate 2. After the sprue plate 23 and the fixed mold plate 2 are closed, the curvature of the rubber pad 25 increases, which facilitates the falling off of the sprue material stuck on the rubber pad 25. Alternatively, during the mold opening process of the sprue plate 23 and the fixed mold plate 2, the curvature of the rubber pad 25 gradually decreases, that is, the surface of the rubber pad 25 changes, which facilitates the movement of the sprue material on the rubber pad 25 and reduces the retention of the sprue material.

[0045] like Figure 3-6 The receiving part 2 has the same structure as the receiving part 1. That is, a rubber pad layer 25 is also provided on the lower end face of the moving mold plate 1 and the fixed mold plate 2. This guides the injection molded part out of the mold.

[0046] Alternatively, the injection molded part is as follows Figure 7 The valve core 3 shown is a cylinder 32 with several cavities 31 at one end and a cylindrical protrusion 33 coaxially arranged at the center of the cylinder 32 at the other end. When it is pushed out of the driven template 1 of the injection molded part, one end of the cylinder 32 moves out of the driven template 1 first, and the other end of the protrusion 33 moves out of the driven template 1 later.

[0047] like Figure 3-6 The receiving component two includes a transfer track located between the fixed mold plate 2 and the moving mold plate 1. The transfer track is used to guide the injection molded part from the moving mold plate 1 to below the moving mold plate 1, and to adjust the injection molded part from a horizontal position to a vertical position. The specific implementation method is as follows:

[0048] like Figure 3-6 The transfer track includes two guide rods 17 distributed opposite to each other. The gap between the two guide rods 17 allows the protrusion 33 on one side of the injection molded part to enter. The two guide rods 17 include a vertical section at the upper end and an arc-shaped section connected to the vertical section, which makes the axis of the injection molded part vertically distributed. The transfer track is also equipped with a power source, which is a cylinder 171. The piston rod of the cylinder 171 is distributed upward, and a lifting plate 172 is fixed on the piston rod of the cylinder 171. The lifting plate 172 is provided with a support rod to lift the two guide rods 177 away from the lifting plate 172. The power source enables the transfer track to enter between the fixed platen 2 and the moving platen 1 after the mold is opened.

[0049] like Figure 3-6The power source drives the transmission track to move vertically up and down. The upper outer walls of the two guide rods 17 are provided with horizontal rods 173 extending away from the guide rods 17. The upper ends of the two horizontal rods 173 are fixedly connected with U-shaped mounting covers 174. The mounting covers 174 are fitted on the outside of the injection molded part that is removed from the moving template 1. The openings of the mounting covers 174 are distributed in the direction of the moving template 1. The vertical plate of the mounting covers 174 facing the moving template 1 has an extension plate 175 extending in the direction of the guide rods 17. The extension plate 175 is distributed parallel to the vertical section of the guide rods 17 and extends to the vertical section of the guide rods 17. The purpose is to facilitate the injection molded part to slide along the vertical section of the guide rods 17 towards the arc section.

[0050] like Figure 3-6 It also includes a transmission belt 18 located on one side of the moving template 1. The two transmission belts 18 are horizontally distributed and arranged opposite each other. The gap between the two transmission belts 18 allows the protrusions 33 on the injection molded part to enter. The two transmission belts 18 are used to receive the injection molded part moving out of the arc section to realize the continuous output of the injection molding machine. The two transmission belts 18 are in contact with the lower end face of the injection molded part. When the power source drives the transmission track to guide the injection molded part between the moving template 1 and the fixed template 2, the outlet of the transmission track is connected to the inlet of the two transmission belts 18.

[0051] Working principle of receiving part two:

[0052] First, after the moving mold plate 1 and the fixed mold plate 2 are opened, the cylinder 171 pushes the lifting plate 172 to move upward, so that the mounting cover 174 on the two guide rods 17 is aligned with the cavity plate 11 on the moving mold plate 1. Then the ejector rod ejects the injection molded part, so that the injection molded part is located inside the mounting cover 174, and the protrusion 33 of the injection molded part is located above the two guide rods 17.

[0053] Step 2: After the injection molded part is pushed out of the moving template 1, it falls freely downwards, causing the protrusion 33 of the injection molded part to enter between the two guide rods 17, while the cylindrical part 32 of the injection molded part slides along the guide rods 17. When the injection molded part slides to the lower end of the guide rods 17, the axis of the injection molded part becomes vertically distributed and slides onto the two transmission belts 18. Then, it is driven by the transmission belts 18 to move a distance away from the guide rods 17, so that the next injection molded part can slide onto the transmission belts 18.

[0054] Step 3: Cylinder 171 drives guide rod 17 and mounting cover 174 to move out between moving template 1 and fixed template 2, and to be located below both, so as to facilitate mold closing.

[0055] Repeating steps one through three allows for continuous ejection of the injection molded parts. The structure is simple and ingenious.

[0056] Two guide rods 17 are equipped with infrared sensors on opposite sides to detect whether the injection molded part has entered the transmission track. Specifically, an infrared transmitter and an infrared receiver are embedded on the opposite side wall of the two guide rods 17, respectively. The specific usage method is as follows: after the guide rods 17 move upward between the moving template 1 and the fixed template 2, the injection molded part can slide over the infrared sensors from the two guide rods 17 within a time T. If no injection molded part slides down after 5 seconds (more than T), it means that the injection molded part is stuck to the top rod and has not fallen freely. At this time, a baffle 176 is provided at the upper end of the mounting cover 174, located directly above the injection molded part. The baffle 176 is located directly above the center of the injection molded part. When the infrared sensor detects that no injection molded part has fallen within the preset time T, the infrared sensor does not detect signal interruption. Then, the cylinder 171 is controlled to move downward a small distance, which causes the baffle 176 to knock the injection molded part down. Then, the cylinder 171 is controlled to move upward to reset.

[0057] Infrared sensors are preferentially distributed in the vertical section of guide rod 17.

[0058] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
