In a private enterprise, an employee was injured and died, but he bought work-related injury insurance, but did not sign a labor contract. Can he claim compensation for work-related injuries?

This is no longer a work injury, but a work death. As the heir of the laborer, you can claim compensation for the death of the employer. If the employer pays the insurance in full accordance with the employee's wage income, the employer will not bear the responsibility for work-related injury and death. If you don't pay, you will take full responsibility. If you don't pay enough insurance, you must bear the responsibility that social security does not bear part of the difference compensation. In addition, if you don't sign a labor contract, you may have to pay the maximum salary of 1 1 month. What I don't understand is that you can apply for work-related injury insurance without signing a labor contract.
