Description
Technical Field
[0001] The utility model relates to the technical field of electronic water pumps, in particular to a fixture for clamping a threaded clamp on a water pump housing. Background Art
[0002] There are many parts in the shell of the automotive electronic water pump. Figure 1 The plastic clamp 01 with internal threads is shown. The plastic clamp is formed by injection molding. In order to reduce the cost of the injection mold and the injection molding cycle, the core pulling in the injection mold is set to a telescopic core. Since the plastic clamp is provided with internal threads, when the plastic clamp formed by injection molding is demolded, the plastic clamp stagnates on the telescopic core and moves synchronously with the telescopic core. Therefore, the plastic clamp needs to be removed from the telescopic core by manual removal, and the demolding efficiency is low. In addition, when manually removing the parts, the internal threads on the plastic clamp are easily damaged, affecting the product quality of the plastic clamp. Utility Model Content
[0003] In order to improve the demolding efficiency and product quality of plastic clamps, the utility model proposes a threaded product clamping jig, which includes a clamp and a support frame, the clamp includes a clamping drive, a connecting member and at least two clamping plates, the clamping drive is mounted and fixed on the support frame, the clamping plate is connected to the clamping drive via the connecting member, and the clamping plates are relatively arranged on the same circumference and move in a radial direction under the drive of the clamping drive. When using the threaded product clamping jig of the utility model to remove the plastic clamp with internal threads that is stuck on the telescopic core in the injection mold, first use the clamping drive to drive the clamp plate to move outward along the radial direction of the circumference of the clamp plate, even if the clamping inner diameter of the clamp plate is larger than the outer diameter of the plastic clamp to be clamped, so that the threaded product clamping jig of the utility model is sleeved on the periphery of the plastic clamp to be clamped; then use the clamping drive to drive the clamp plate to move inward along the radial direction of the circumference of the clamp plate, even if the clamping inner diameter of the clamp plate is reduced, so that the clamp plate clamps the outer wall of the plastic clamp to be clamped, and then remove the plastic clamp stuck on the telescopic core, and complete the demolding of the plastic clamp. It can be seen that the use of the threaded product clamping jig of the utility model can quickly remove the plastic clamp from the telescopic core in the injection mold, improve the demolding efficiency of the plastic clamp, and it is not easy to cause damage to the plastic clamp during the demolding process, thereby improving the product quality of the plastic clamp.

In this way, the connecting member is formed by vertically connecting the connecting plate and the splint fixing plate, which has a simple structure, is easy to manufacture and has low cost. Furthermore, weight-reducing holes are provided on the splint fixing plate. In this way, by providing weight-reducing holes on the splint fixing plate, the deadweight of the threaded product clamping jig of the utility model can be reduced, the energy consumption required for the operation of the threaded product clamping jig of the utility model can be reduced, and the material consumption for manufacturing the threaded product clamping jig of the utility model can be reduced, thereby reducing the manufacturing cost of the threaded product clamping jig of the utility model.

Such a support frame has a simple and stable structure. Furthermore, the connecting end of the substrate is provided with a connecting through hole for connecting with a manipulator, and the free end of the substrate is provided with a limiting rod, and the free end of the limiting rod faces the clamping plate. In this way, when using the threaded product clamping jig of the utility model to clamp the threaded product, the connecting through hole on the connecting end of the substrate can be used to connect with the manipulator, so that the threaded product clamping jig of the utility model can be extended into a mold with a small space to clamp the threaded product; the limiting rod located at the free end of the substrate can be used to limit the threaded product clamped by the clamping plate, so as to prevent the threaded product clamped by the threaded product clamping jig of the utility model from slipping out of the gap between two adjacent clamping plates, which affects the threaded product clamping jig of the utility model.
[0006] Preferably, the clamping drive is mounted and fixed on the fixed plate and is located between the base plate and the fixed plate. In this way, the clamping drive is mounted and fixed on the fixed plate in the support frame and is located between the base plate and the fixed plate, which is convenient for the installation and fixation of the clamping drive and can avoid the interference between the connector connected to the clamping drive and the support frame, which affects the clamping of the threaded product by the threaded product clamping fixture of the utility model.

The straightening plate is parallel to the fixed plate and connected to the fixed plate through the connecting rod, and the straightening plate is located between the fixed plate and the clamping plate. In this way, when using the threaded product clamping jig of the utility model to clamp threaded products, the straightening plate in the straightening member can be used to press the threaded product to be clamped, so as to prevent the threaded product to be clamped from shifting and tilting during the clamping process, which affects the clamping of the threaded product by the threaded product clamping jig of the utility model. Furthermore, the connecting rod is installed on the fixed plate through a sliding bearing, and the sliding end of the connecting rod connected to the same straightening plate away from the straightening plate passes through the fixed plate and is connected to the sliding fixing rod.

[0010] Next, combine Figure 2 , the threaded product clamping fixture of the utility model is described in detail.
[0011] like Figure 2As shown, the threaded product clamping jig of the utility model includes a clamp, a support frame and a straightening member. Among them, the clamp includes a clamping drive 11, a connecting member 12 and at least two clamps 13, the clamping drive 11 is installed and fixed on the support frame, the clamp 13 is connected to the clamping drive 11 through the connecting member 12, and the clamp 13 is relatively surrounded on the same circumference and moves in the radial direction under the drive of the clamping drive 11. Preferably, the connecting member 12 includes a connecting plate 121 and a clamp fixing plate 122, the positioning end of the connecting plate 121 is connected to the clamping drive 11, and the connecting end of the connecting plate 121 is vertically connected to the clamp fixing plate 122. In this way, the connecting member 12 is formed by vertically connecting the connecting plate 121 and the clamp fixing plate 122, which has a simple structure, is easy to manufacture and has low cost. Preferably, a weight reduction hole 1221 is provided on the clamp fixing plate 122. In this way, setting the weight-reducing hole 1221 on the splint fixing plate 122 can not only reduce the deadweight of the threaded product clamping jig of the utility model and reduce the energy consumption required for the operation of the threaded product clamping jig of the utility model, but also reduce the material consumption in making the threaded product clamping jig of the utility model and reduce the production cost of the threaded product clamping jig of the utility model.
[0012] like Figure 2 As shown, the support frame includes a base plate 21, a support plate 22 and a fixing plate 23, the base plate 21 and the fixing plate 23 are arranged in parallel, and the support plate 22 is vertically connected to the base plate 21 and the fixing plate 23 at the end of the fixing plate 23. Such a support frame has a simple and stable structure. Preferably, a connecting through hole 211 for connecting to a manipulator (not shown in the figure) is provided at the connecting end of the base plate 21, and a limiting rod 24 is provided at the free end of the base plate 21, and the free end of the limiting rod 24 faces the clamping plate 13. In this way, when the threaded product clamping jig of the utility model is used to clamp the threaded product 3, the connecting through hole 211 on the connecting end of the substrate 21 can be used to connect with the manipulator, so that the threaded product clamping jig of the utility model can be inserted into the mold with a narrow space to clamp the threaded product 3; the limiting rod 24 located at the free end of the substrate 21 can be used to limit the threaded product clamped by the clamping plate, so as to prevent the threaded product 3 clamped by the threaded product clamping jig of the utility model from slipping out of the gap between two adjacent clamping plates 13, which affects the threaded product clamping jig of the utility model to clamp the threaded product 3. Preferably, the clamping drive member 11 is installed and fixed on the fixing plate 23 and is located between the substrate 21 and the fixing plate 23. In this way, the clamping drive member 11 is installed and fixed on the fixing plate 23 in the support frame and is located between the substrate 21 and the fixing plate 23, which is convenient for the installation and fixing of the clamping drive member 11, and can also avoid the interference between the connecting member 12 connected to the clamping drive member 11 and the support frame, which affects the clamping of the threaded product 3 by the threaded product clamping jig of the utility model. Preferably, the gripping drive member 11 is a finger slide rail cylinder.

Preferably, the connecting rod 42 is installed on the fixed plate 23 through a sliding bearing 43, and the sliding end of the connecting rod 42 connected to the same straightening plate 41 away from the straightening plate 41 passes through the fixed plate 23 and is connected to the sliding fixing rod 44. In this way, when the threaded product clamping fixture of the utility model is used to clamp the threaded product 3, as the threaded product 3 to be clamped is ejected out of the injection mold, the straightening plate 41 lightly presses against the threaded product 3 to be clamped and as the threaded product 3 to be clamped is ejected, the connecting rod 42 slides in the sliding bearing 43, so that the straightening plate 41 moves toward the fixed plate 23, thereby preventing the threaded product 3 to be clamped from being unable to be ejected out of the injection mold due to the pressure of the straightening plate 41, affecting the demolding of the threaded product 3 to be clamped.
[0014] When using the threaded product clamping jig of the utility model to remove the plastic clamp with internal threads that is stuck on the telescopic core in the injection mold, first use the clamping drive to drive the clamp plate to move outward along the radial direction of the circumference of the clamp plate, even if the clamping inner diameter of the clamp plate is larger than the outer diameter of the plastic clamp to be clamped, so that the threaded product clamping jig of the utility model is sleeved on the periphery of the plastic clamp to be clamped; then use the clamping drive to drive the clamp plate to move inward along the radial direction of the circumference of the clamp plate, even if the clamping inner diameter of the clamp plate is reduced, so that the clamp plate clamps the outer wall of the plastic clamp to be clamped, and then remove the plastic clamp stuck on the telescopic core, and complete the demolding of the plastic clamp.
