Description

Technical Field

[0001] This utility model relates to the field of automotive shock absorber mold technology, and more specifically to an automotive shock absorber mold for aluminum part leakage detection. Background Technology

[0002] A mold is a fixed tool designed and produced in stamping, punching, and casting technologies to facilitate the forming of parts. Molds are used in the production of various parts. In the production of raw material plates for automotive shock absorbers, the forming and manufacturing of shock absorber brackets, and the forming and processing of shock absorber washers all require molds. The use of molds accelerates the production efficiency of shock absorbers.

[0003] For example, in the prior art disclosure number CN211616425U, there is a mold for a raw material plate of an automotive shock absorber. This utility model has a reasonable design. After the upper mold and the lower mold overlap, the locking buckle is engaged with the vertical plate to fix the position between the upper mold and the lower mold. The injection is carried out through the injection tube from the injection port, which reduces the spillage of raw materials, makes it easier to maintain the stability of the mold during the injection process, and facilitates the processing and forming of the raw material plate component of the automotive shock absorber.

[0004] However, the existing technology has the following problems when used: When the raw material plate of the car shock absorber is injection molded, aluminum parts will be placed on the raw material plate of the car shock absorber. Since there are many raw material plates of car shock absorbers, there will be a problem of aluminum parts being lost to the customer, resulting in customer returns and fines. Based on this, this utility model provides a car shock absorber mold for aluminum part leakage detection. Utility Model Content

[0005] To overcome the aforementioned deficiencies in the prior art, this utility model provides an automotive shock absorber mold for detecting missing aluminum parts. Through the cooperation of a photoelectric sensor and multiple movable spring pins, when the mold is closed, the aluminum part on the mold core will press the movable spring pins back. When the photoelectric sensor receives a signal, the product can be injected. Conversely, if an aluminum part is missing, the movable spring pins will not be pressed back, the photoelectric sensor will not receive a signal, and the product cannot be injected. This method can detect missing aluminum parts, avoiding customer returns and fines due to missing aluminum parts, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a car shock absorber mold for aluminum part leakage detection, comprising a front mold and a rear mold. The front mold is fixedly equipped with a detachable photoelectric sensor at its front end, and a plurality of detachable movable spring pins are fixedly equipped at its rear end. A groove is provided at the rear end of the photoelectric sensor. Detachable mold cores are fixedly equipped at the rear end of the front mold and the front end of the rear mold for placing the car shock absorber raw material plate. Two aluminum parts are provided on the car shock absorber raw material plate. A plurality of through holes are provided at the front end of the front mold, and the rear ends of the plurality of movable spring pins pass through the plurality of through holes respectively, and the rear ends of the plurality of movable spring pins contact the tops of the plurality of aluminum parts respectively. A mounting plate is fixedly equipped at the rear end of the rear mold, and limiting mechanisms for improving the movement stability of the front mold are provided on both sides of the front end of the mounting plate.

[0007] In a preferred embodiment, the limiting mechanism includes a bracket, with two brackets fixed on both sides of the front end of the mounting plate. The rear ends of the two brackets are rotatably connected to round rods, and each round rod is fitted with a slider. By using the sliders in cooperation with the round rods, the upper template can be supported, preventing the upper template from shifting and affecting the accuracy of mold closing.

[0008] In a preferred embodiment, two spring pins are fixedly inserted through each of the two sliders, and two slots are opened on both sides of the front mold. One end of each spring pin is inserted into the slot, and the spring pins are used to fix the front mold and the slider together, so as to facilitate the disassembly and replacement of the front mold by the operator.

[0009] In a preferred embodiment, the photoelectric sensing device is connected to a cable, which is placed in a cable groove to avoid the cable being messy and affecting the injection molding process.

[0010] In a preferred embodiment, the mounting plate has multiple mounting holes at its front end, which are distributed on the outside of the rear mold for fixing the mounting plate.

[0011] In a preferred embodiment, the front mold and the rear mold, and the photoelectric sensing device and the front mold are detachably fixed together by multiple locking components, which facilitates the disassembly of the front mold, the rear mold, and the photoelectric sensing device by the staff.

[0012] In a preferred embodiment, each movable spring pin includes a mounting block, and multiple mounting blocks are respectively fixed to the front end of the photoelectric sensing device. A needle body 1 passes through the interior of each mounting block, and a needle body 2 is fixedly provided at the rear end of the needle body 1. The rear end of the needle body 2 passes through the photoelectric sensing device and the through hole in sequence and contacts the front end of the aluminum part. A return spring is sleeved on the outer wall of each needle body 1. The front end of the return spring is fixed to the rear end of the mounting block. When the needle body 2 contacts the aluminum part, the aluminum part pushes the needle body 2 to move backward, and the front end of the needle body contacts the photoelectric sensing device to generate a signal, thereby ensuring the assembly of the aluminum part.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] This invention utilizes a photoelectric sensor and multiple movable spring pins. When the front and rear molds are closed, the aluminum parts on the mold core will press the movable spring pins back, and the photoelectric sensor will receive a signal, allowing the injection molding machine to inject the product. Conversely, if an aluminum part is missing, the movable spring pins will not be pressed back, the photoelectric sensor will not receive a signal, and the injection molding machine will not be able to inject the product. This method can detect missing aluminum parts and prevent customer returns and fines caused by missing aluminum parts.

[0015] The front mold is supported by two sliders, which prevents the front mold from tilting and shifting when the photoelectric sensor is separated from the front mold, thus avoiding affecting the subsequent mold closing. At the same time, it is convenient for staff to inspect and replace the photoelectric sensor and the movable spring pin. The structure is simple and the operation is very convenient.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Refer to the instruction manual appendix Figure 1-7 This utility model provides a car shock absorber mold for aluminum part leakage detection, including a front mold 1 and a rear mold 2. The front mold 1 is fixedly provided with a detachable photoelectric sensor 3. The front mold 1 and the rear mold 2, and the photoelectric sensor 3 and the front mold 1 are detachably fixed together by multiple locking pieces 14, which facilitates the disassembly of the photoelectric sensor 3, the front mold 1, and the rear mold 2.

[0028] The photoelectric sensing device 3 is fixedly provided with a plurality of detachable movable spring pins 4 at its rear end. Specifically, each movable spring pin 4 includes a mounting block 401. The plurality of mounting blocks 401 are respectively fixed to the front end of the photoelectric sensing device 3. A needle body 402 passes through the interior of each mounting block 401. A needle body 403 is fixedly provided at the rear end of the needle body 402. The rear end of the needle body 403 passes through the photoelectric sensing device 3 and the through hole 9 in sequence and contacts the front end of the aluminum part 8. A return spring 404 is sleeved on the outer wall of each needle body 402. The front end of the return spring 404 is fixed to the rear end of the mounting block 401. When the needle body 403 contacts the aluminum part 8, the aluminum part 8 pushes the needle body 403 to move backward. The front end of the needle body 402 contacts the photoelectric sensing device 3 to generate a signal, thereby ensuring the assembly of the aluminum part 8.

[0029] The photoelectric sensing device 3 has a wire groove 5 at its rear end for storing the probe cable 12. The rear end of the front mold 1 and the front end of the rear mold 2 are both fixed with detachable mold cores 6 for placing the automotive shock absorber raw material plate 7. The automotive shock absorber raw material plate 7 is provided with two aluminum parts 8.

[0030] Furthermore, the front mold 1 has multiple through holes 9 at its front end, and the rear ends of multiple movable spring pins 4 pass through the multiple through holes 9 respectively. The rear ends of the multiple movable spring pins 4 respectively contact the top of multiple aluminum parts 8. The rear end of the rear mold 2 is fixedly provided with a mounting plate 10. Both sides of the front end of the mounting plate 10 are provided with limiting mechanisms 11 to improve the movement stability of the front mold 1.

[0031] Furthermore, the photoelectric sensing device 3 is connected to a cable 12, which is placed in the cable groove 5 to avoid the cable 12 being messy and affecting the injection molding process. The front end of the mounting plate 10 has multiple mounting holes 13, which are distributed on the outside of the rear mold 2 for fixing the mounting plate 10.

[0032] When this mold is installed on an injection molding machine, the operator first places the raw material plate 7 of the car shock absorber into the mold core 6 on the rear mold 2. Then, the moving mechanism on the injection molding machine drives the front mold 1 and the photoelectric sensor 3 to move. Multiple movable spring pins 4 at the bottom of the photoelectric sensor 3 pass through multiple through holes 9. When the front mold 1 and the rear mold 2 are closed, the aluminum part 8 will press the second pin 403 and the first pin 402 back. The first pin 402 contacts the photoelectric sensor 3, and the photoelectric sensor 3 receives a signal. The injection molding machine can then inject the product. Conversely, if the aluminum part 8 is missing, the movable spring pins will not be pressed back, and the photoelectric sensor 3 will not receive a signal. In this case, the injection molding machine cannot inject the product. This method can detect the missing aluminum part 8 and avoid customer returns and fines due to the missing aluminum part 8.

[0033] Refer to the instruction manual appendix Figure 1-7 The limiting mechanism 11 includes a bracket 1101. Two brackets 1101 are fixed on the front sides of the mounting plate 10 respectively. The rear ends of the two brackets 1101 are rotatably connected to round rods 1102. Slider 1103 is sleeved on the two round rods 1102. By using the cooperation between the slider 1103 and the round rod 1102, the stability of the front mold 1 when moving can be improved, thereby improving the mold closing accuracy between the front mold 1 and the rear mold 2.

[0034] Two spring pins 1104 are fixedly inserted through each of the two sliders 1103. Two slots 1105 are opened on both sides of the front mold 1. One end of the spring pin 1104 is inserted into the slot 1105. The spring pins 1104 are used to fix the front mold 1 and the sliders 1103 together, so as to facilitate the workers to disassemble the front mold 1 and replace it.

[0035] By setting a slider 1103 on the front mold 1, when the mold is installed on the injection molding machine, the photoelectric sensor 3 is connected to the moving mechanism on the injection molding machine. The photoelectric sensor 3 drives the front mold 1 to separate from the rear mold 2, which makes it easier for the operator to pick up the raw material plate 7 of the car shock absorber. At the same time, the photoelectric sensor 3 and the front mold 1 can be separated. The two sliders 1103 support the front mold 1 to prevent the front mold 1 from tilting or shifting, which would affect the subsequent mold closing. Furthermore, the photoelectric sensor 3 is connected to the moving mechanism of the injection molding machine, which separates the photoelectric sensor 3 from the front mold 1. This makes it easier for the operator to inspect and replace the photoelectric sensor 3 and the movable spring pin. The structure is simple and the operation is very convenient.

[0036] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
