Problems solved by technology

[0003] Before injection molding, it is necessary to compress the upper and lower molds to ensure the yield of injection molding products. The existing way to compress the upper and lower molds is to fix the connecting parts fixed on the upper and lower molds with bolts, and it takes a lot of time. Position setting, bolt fixing and disassembly are troublesome, resulting in low work efficiency and inconvenient use

Embodiment 1

[0024] see Figure 1~5 , in an embodiment of the present invention, a clamping structure for an injection mold includes a clamp arm 1 and a transmission box 23; two clamp arms 1 are provided and both pass through the transmission box 23, and the two clamp arms 1 are arranged in a staggered manner, and A second gear 18 is arranged between the two clamp arms 1 inside the transmission box 23, and the second gear 18 meshes with the bar teeth mounted on the clamp arms, and the second gear 18 is fixed on the second sleeve 21 , the second sleeve 21 is rotatably connected with the first sleeve 20 on which the tightening assembly is installed, the inner side of the first sleeve 20 and the second sleeve 21 is inserted with a locking assembly, when the locking assembly is triggered, The first sleeve 20 and the second sleeve 21 rotate at the same time, so as to realize that the first sleeve 20 is driven to rotate by the tightening assembly provided. When the first sleeve 20 rotates, due t...

Embodiment 2

[0033] In the embodiment of the present invention, in order to realize the linear sliding of the clamp arm 1, the clamp arm 1 is provided with a chute 8, and the chute 8 is slidably matched with the slider 9 arranged on the transmission box 23, thereby realizing the clamp arm 1. Linear slide.

Abstract

The invention relates to the technical field of injection molds and specifically relates to a clamping structure applied to an injection mold. The clamping structure comprises clamping arms and a transmission case, wherein the quantity of the clamping arms is two and both of the clamping arms penetrate the transmission case; the two clamping arms are disposed in a staggered manner; a second gear is disposed between the two clamping arms which are located on inner sides of the transmission case; the second gear is meshed with bar-shaped teeth installed on the clamping arms; the second gear is fixed on a second sleeve; the second sleeve is in rotary connection with a first sleeve which is equipped with a tightening assembly; and locking assemblies are inserted on inner sides of the first sleeve and the second sleeve. The first sleeve is driven by the disposed tightening assembly to rotate; when the first sleeve is rotated, the second sleeve flows the first sleeve to rotate because of existence of a locking mechanism; and during rotation of the second sleeve, the two clamping arms are driven by the bar-shaped teeth and the second gear to move towards each other, so fastening is realized. Operations are convenient; the clamping structure can be applied to clamping of the injection molds with different specifications; and the applicable scope is wide.

Description

technical field [0001] The invention relates to the technical field of injection molds, in particular to a clamping structure for injection molds. Background technique [0002] Injection mold is a tool for producing plastic products; it is also a tool for giving plastic products complete structure and precise dimensions. Injection molding is a processing method used in the mass production of certain complex-shaped parts. Specifically, it refers to injecting the heated and melted plastic into the mold cavity under high pressure from the injection molding machine, and after cooling and solidifying, a molded product is obtained. [0003] Before injection molding, it is necessary to compress the upper and lower molds to ensure the yield of injection molding products. The existing way to compress the upper and lower molds is to fix the connecting parts fixed on the upper and lower molds with bolts, and it takes a lot of time. Position setting, bolt fixing and disassembly are tr...
