Preferably, two sides of the top of the base are provided with supporting seats; a concave groove is formed in the supporting seat; the concave groove is provided with an installation cavity; the elastic support frame comprises a support column and a spring; the spring is arranged in the mounting cavity; the support column is arranged at the bottom of the bottom die; the bottom of the supporting column extends into the mounting cavity in a sliding mode and is arranged at the top of the spring in a pressing mode.
Preferably, the bottom of the top die is provided with a positioning column; the top of the bottom die is provided with a positioning hole; the positioning column is arranged in the positioning hole in a sliding mode.
The utility model has the advantages that: the bottom die is supported by the elastic support frame, and when the first lifting driving device drives the top die to press down and match the bottom die, the bottom die is pressed down elastically, so that the top of the demolding rod moves upwards relatively to block the bottom of the mold cavity; when the injection molding is finished and the demolding is needed, the first lifting driving device drives the top mold to move upwards, the bottom mold automatically moves upwards under the action of the elastic supporting frame, the demolding rod automatically separates from the product, and finally the second lifting driving device drives the demolding rod to move upwards to eject the product out of the mold. Therefore, the utility model discloses can make stripper bar and product separation automatically, need not rely on external force again behind the ejecting product of stripper bar to break away from stripper bar and product, labour saving and time saving.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. It will be understood that when an element is referred to as being "secured to" or "disposed on" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. When one element is referred to as being "fixedly attached" to another element, it can be fixedly attached by welding, bolting, gluing, or the like.
Referring to fig. 1-2, in a preferred embodiment of the present invention, a mold for rapid demolding is disclosed, which includes a base 1, an injection molding line 2, a demolding mechanism and an injection molding device; elastic support frames 3 are arranged at the tops of two sides of the base 1; the injection molding production line 2 is positioned above the base 1; the demoulding mechanism comprises a first lifting driving device 4, a second lifting driving device 5 and a demoulding rod 6; the first lifting driving device 4 is arranged at the bottom of the injection molding production line 2; the second lifting driving device 5 is arranged on the base 1; the demoulding rod 6 is arranged at the top of the driving end of the second lifting driving device 5; the injection molding device comprises a top mold 7 and a bottom mold 8; the top die 7 is arranged at the bottom of the driving end of the first lifting driving device 4; the bottom die 8 is arranged at the top of the elastic support frame 3, and the top die 7 and the bottom die 8 can surround to form a die cavity; a sliding hole 9 communicated with the mold cavity is formed in the bottom mold 8; the top of the demoulding rod 6 is arranged in the sliding hole 9 in a sliding way.
