The utility model relates to tableware production mould technical field discloses a kind of starch tableware mould, including outer mould and inner mould, outer mould and inner mould are made of breathable steel, outer mould is sleeved on inner mould, and the inner cavity surface of outer mould and the outer surface of inner mould are formed between interval defined space, starch material for making tableware is filled in defined space, the utility model provides a kind of starch tableware mould, outer mould and inner mould are made of breathable steel, the water vapor produced in the high-temperature high-pressure forming process of breathable steel's breathable performance can be made starch material pass through mould and discharge quickly, avoid forming high-pressure air cavity and gas trapping phenomenon in mould inside;Defined space is formed by outer mould sleeveing inner mould, so that starch material filling position and range are fixed, guarantee the even distribution of pressure in forming process, to solve the problem of uneven tableware wall thickness caused by water vapor cannot be discharged in time smoothly, improve tableware structural strength and service performance.

The application relates to an integrated plastic wind guide cover injection molding method and a mold thereof, and relates to the technical field of injection molds.The method comprises the following steps: collecting mold information and oil information in response to a mold closing completion signal; determining a connecting portion wall thickness, a contact threshold value and a breaking value according to the mold information; matching an oil threshold value through the oil information; controlling an oil brush preset below a blade to move upwards and collecting a capacitance value until the capacitance value is greater than the breaking value, and defining the capacitance value at the moment as a contact capacitance value; controlling the blade to move based on the connecting portion wall thickness; injecting glue into a hard glue cavity in response to a blade stop signal; controlling the blade to reset based on the connecting portion wall thickness in response to a cooling completion signal, and then injecting glue into a soft glue cavity, and completing integrated injection molding operation after cooling. The application has the effects of avoiding color mixing and improving product quality.

According to the self-adaptive compensation clamp, an X-Y direction compensation module is formed by the first linear sliding rail and the second linear sliding rail which are perpendicular to each other in direction, displacement deviation, generated by stress release, of a workpiece in the horizontal plane is absorbed and compensated, rigid constraint of a traditional bolt pressing plate is replaced, and meanwhile the self-adaptive compensation clamp has the advantages of being simple in structure and convenient to use. A Z-direction height and angle self-adaptive mechanism is formed by matching a plurality of adjusting cylinders capable of independently and axially stretching out and drawing back at the bottom of the first self-adaptive unit with the connecting unit, and the Z-direction height and angle self-adaptive mechanism can actively fit workpiece bending and torsion caused by self-weight or stress release, so that self-weight deformation is effectively resisted; and finally, a clamping air cylinder and a clamping arm which are integrated in a connecting unit are used for locking an adjusting cylinder, and a locking device at the bottom is used for locking the position of an X-Y compensation module, so that stable support is provided for finish machining, the phenomena of non-uniform wall thickness and over-cutting of the web plate are avoided, multi-dimensional self-adaptive compensation and accurate locking of machining deformation of the large thin-wall part are realized, and the machining precision of the large thin-wall part is improved. And the size precision and the shape precision of final machining are also ensured.
