Problems solved by technology

In the prior art, when taking out the workpiece, two methods are usually used: manual picking and mechanical picking. The manual picking is not only slow, but also dangerous, which is likely to cause safety accidents; while the mechanical picking in the prior art Usually, the workpiece is directly ejected from the injection mold through the ejection mechanism, and the workpiece is easy to fall into the injection mold during the falling process, resulting in various failures and reducing the operation stability of the injection molding machine
Especially for products with one mold and multiple cavities, such as plastic bottle caps of beverage bottles, the work efficiency of manual pick-up is even lower, and if the plastic bottle caps are ejected by the ejector mechanism, the plastic bottle caps will fall due to Its own gravity is lighter, and the probability of falling into the injection mold is greater

Embodiment 1

[0031] Such as figure 1 As shown, the injection molding machine with a demoulding detection device includes a base 1 on which a fixed template 2 and a movable template 3 are arranged. The fixed template 2 and the movable template 3 are connected by a tie rod, and the movable template 3 and the fixed template 2 are closed. A plurality of mold cavities for forming plastic bottle caps are formed, and the opening of the plastic bottle cap is set outward after the plastic bottle cap is formed.

[0032] Such as figure 1 , figure 2 As shown, this injection molding machine also includes a pick-up device 4, and the pick-up device 4 includes a pick-up plate 5, and the pick-up plate 5 is provided with a clamping structure 6 that can fix or loosen the plastic bottle cap. A lifting mechanism 7 capable of driving the pick-up plate 5 to move up and down reciprocatingly is provided. Lifting mechanism 7 among the present embodiment comprises several cylinders one 8 that are arranged in ver...

Embodiment 2

[0037] Such as Figure 4 , Figure 5 As shown, this embodiment is roughly the same as Embodiment 1, the difference is that a fixing seat 26 is provided at the outer end of the piston rod 10 in this embodiment, and a cylinder 3 27 is arranged on the fixing seat 26 along the horizontal direction. , cylinder three 27 comprises cylinder body three and piston rod three, and the inner end of piston rod three is inserted in cylinder body three and can do telescopic reciprocating motion, and the outer end of piston rod three is fixed on the pick-up plate 5, and pick-up plate 5. A cylinder 28 is arranged along the horizontal direction. The cylinder 28 includes a cylinder body 28 and a piston rod 4. The inner end of the piston rod 4 is inserted in the cylinder body 4 and can perform telescopic reciprocating motion. The outer end of the piston rod 4 is fixed There is a baffle plate 29 parallel to the pick-up plate 5, the clamping structure 6 includes several tweezers, the tweezers inclu...

Abstract

The invention provides an injection molding machine with a demolding detecting device, belonging to the technical field of moulds and solving the technical problems of relatively poor operation stability and the like of the injection molding machine in the prior art. The injection molding machine comprises a stand, wherein the stand is provided with a fixed mold plate and a moving mold plate which are connected through a pull rod, the moving mold plate and the fixed mold plate are closed to form a plurality of mold cavities for molding plastic bottle caps, and openings of the plastic bottle caps are outwards arranged after the plastic bottle caps are molded. The injection molding machine also comprises a piece taking device, wherein the piece taking device comprises a piece taking plate; the piece taking plate is provided with a clamping structure capable of fixing or loosing the plastic bottle caps; a rack is fixedly provided with a lifting mechanism capable of driving the piece taking plate to do lifting reciprocation and is also provided with a holding frame for holding the plastic bottle caps; and the holding frame is provided with a demolding detecting device for detecting whether all the plastic bottle caps fall off from the mold cavities. The injection molding machine has the advantages of good operation stability and the like.

Description

technical field [0001] The invention belongs to the technical field of moulds, and relates to an injection molding machine with a demoulding detection device. Background technique [0002] Injection molding machine is also known as injection molding machine or injection machine. It is the main molding equipment for making thermoplastics or thermosetting materials into various shapes of plastic products with plastic molding molds. Injection molding machine usually consists of injection system, clamping system, transmission system, electrical control system, heating and cooling system, safety monitoring system and so on. The function of the injection system is to heat and plasticize a certain amount of plastic within a specified time in a cycle of the injection molding machine, and then inject it into the mold cavity under a certain pressure and speed. After the injection is completed, the molten material injected into the cavity is kept fixed. The mold clamping system is m...
