[0002] Currently, there are quick-change hydraulic mold stackers on the market, which are used for quick mold change in injection molding machines, aluminum die-casting machines, stamping machines and other machines, saving mold change time and improving production efficiency.

[0003] However, the current rapid mold change hydraulic mold coder has certain usage defects:

[0004] 1. Hydraulic oil pipes are prone to leakage, causing pollution to the working environment.

[0005] 2. Hydraulic pipes are subject to temperature environment restrictions. Excessively cold or high temperatures will affect the normal use of hydraulic oil.

[0006] 3. The price of hydraulic components is relatively expensive, resulting in high cost of the overall hydraulic coder, which is not conducive to large-scale market promotion.

[0007] 4. During use, the hydraulic oil should be replaced regularly and the hydraulic components should be checked for normal operation, which will result in high maintenance costs.

[0008] 5. If the power outage in the working environment lasts for more than 24 hours, the oil pipeline will be depressurized and a common code module device must be added.

[0009] 6. During use, the detection equipment must always monitor the pressure and replenish the pressure at any time, which will produce a certain amount of noise.

[0010] 7. Since the hydraulic ejector has a short working stroke (working stroke 5 mm), the hydraulic mold encoder has strict requirements on the bottom plate of the mold.

[0011] How to effectively solve the above problems is an important direction for the development of current code molders. To this end, the applicant has specially invented an electric die press to solve the various problems existing in the above hydraulic code molders. Utility Model Content
