AI Technical Summary
Injection molds are prone to sticking under pressure and temperature, which can lead to mold damage and safety hazards. This is especially common with molds that produce multiple parts at once, and there is a lack of effective detection methods.
A mold sticking detection fixture for injection molds was designed, including ejector pins and ejector pin seats. The sticking situation is determined by observing whether the ejector pins are pushed up after being inserted into the mold hole. The fixture uses a spring and copper ring structure to achieve rapid detection.
It enables rapid and accurate determination of mold sticking locations, improves inspection efficiency, and prevents mold damage and safety hazards.

Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to a injection mold sticking detection fixture for detecting whether there is sticking in the injection mold. BACKGROUND
[0002] The injection mold often appears sticking due to pressure, temperature and other reasons, and the sticking can cause damage and deformation of the mold, thereby causing greater safety hazards. The sticking of the one-mold-multiple-out injection mold is more common, and a sticking detection fixture suitable for the one-mold-multiple-out injection mold needs to be developed to prevent damage to the injection mold caused by sticking. SUMMARY
[0003] The injection mold sticking detection fixture comprises a top pin one, a top pin two, a top pin three, a top pin four, a top pin five, a top pin six, a top pin seven, a top pin eight, a top pin seat, a handle, a front mold and an injection product, characterized in that: there are eight holes corresponding to eight injection products belonging to one-mold-multiple-out on the front mold, a spring and a copper ring are arranged in the middle of the top pin one, a nut is fixedly arranged at the top end of the top pin one, the copper ring will compress the spring downward when subjected to downward pressure, and if the pressure disappears, the copper ring will be pushed to the bottom of the nut by the spring; the top pin two, the top pin three, the top pin four, the top pin five, the top pin six, the top pin seven and the top pin eight have the same structure as the top pin one, the upper end of the top pin passes through the round hole of the top pin seat and is fixedly arranged in the top pin seat through a gasket, the top pin two, the top pin three, the top pin four, the top pin five, the top pin six, the top pin seven and the top pin eight are fixedly arranged in the remaining round holes on the top pin seat in the same way as the top pin one, and the handle is fixedly arranged at the center of the top pin seat.
[0004] The injection mold sticking detection fixture has the beneficial effects that: the top pins are inserted into the corresponding front mold holes, whether the top pins are lifted is observed to determine whether there are injection parts retained in the corresponding front mold holes, the sticking of the mold can be quickly checked, and the position of the sticking can be quickly determined. BRIEF DESCRIPTION OF DRAWINGS
[0005] Fig. 1 It is an application schematic diagram of the injection mold sticking detection fixture.
[0006] Fig. 2 It is a structure schematic diagram of the top pin one of the injection mold sticking detection fixture in the lifted state.

[0010] Among them: 1. Ejector pin one; 2. Ejector pin two; 3. Ejector pin three; 4. Ejector pin four; 5. Ejector pin five; 6. Ejector pin six; 7. Ejector pin seven; 8. Ejector pin eight; 9. Ejector pin seat; 10. Handle; 11. Front mold; 12. Injection molded product. Detailed Implementation
[0011] As attached Figs. 1-5 As shown, a mold sticking detection fixture for injection molds includes ejector pin 1, ejector pin 2, ejector pin 3, ejector pin 4, ejector pin 5, ejector pin 6, ejector pin 7, ejector pin 8, ejector pin seat 9, handle 10, front mold 11, and injection molded product 12.
[0012] As attached Figs. 1-5 As shown, after the injection mold completes the demolding action, the ejector pins of the injection mold sticking detection fixture are aligned with the corresponding holes on the front mold 11. The handle 10 is moved downwards, thereby driving ejector pins 1, 2, 3, 4, 5, 6, 7, and 8 downwards until the lower ends of each ejector pin contact the bottom of the hole. During this process, if there is a stuck injection molded part in a hole, the corresponding ejector pin will be lifted. By observing the lifting situation of each ejector pin, the sticking situation of each hole on the front mold 11 can be judged and the sticking position can be quickly determined. After the sticking position is marked, the handle 10 is moved upwards, thereby driving ejector pins 1, 2, 3, 4, 5, 6, 7, and 8 upwards until each ejector pin is completely detached from the hole on the front mold 11. During this process, if any ejector pin is lifted, it will return to the initial position under the action of the spring, and the detection action ends. This fixture can quickly determine the sticking point of the mold, improving inspection efficiency.
[0013] The above description is a preferred embodiment of the present utility model and is intended to illustrate the content and concept of this application. The content of this specification should not be construed as a limitation of the present utility model.
