Description

Technical Field

[0001] This utility model relates to the technical field of cell culture dish processing molds, and in particular to a cell culture dish injection mold with a hand-held ring. Background Technology

[0002] Cell culture dishes are core consumables in biomedical experiments. To facilitate handling by operators and avoid hand contamination of the inner wall of the culture dish, the demand for culture dishes with handles is increasing.

[0003] However, existing injection molds used for petri dish production have the following shortcomings: They lack a dedicated molding structure for the handle ring, often relying on subsequent cutting and processing to form the handle ring, which not only increases the number of steps but also easily leads to insufficient connection strength between the handle ring and the dish body. Furthermore, they lack a dedicated thermal circulation structure, or the thermal circulation pipeline layout is scattered, resulting in large temperature fluctuations (above ±5℃) in the cavity area, which easily leads to defects such as shrinkage cavities and deformation in the petri dishes.

[0004] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a cell culture dish injection mold with a hand-held ring, making it more industrially valuable. Utility Model Content

[0005] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a cell culture dish injection mold with a handheld ring.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A cell culture dish injection mold with a handheld ring includes an upper cover plate, an injection part mounting plate, an upper mold base, a lower template and a lower support plate stacked on top of each other from top to bottom, as well as an injection part and an injection cavity assembly. The injection molded part includes an injection molded part body, a main injection pipe installed at the top center of the injection molded part body, and several injection branch pipes installed at the bottom of the injection molded part body. The injection cavity assembly consists of an upper injection cavity seat and a lower injection bump seat from top to bottom. The upper injection cavity seat is installed at the bottom of the upper mold seat. An injection support seat is installed on the lower mold plate outside the lower injection bump seat. The top of the lower injection bump seat passes through the inside of the injection support seat and then forms an injection cavity with the upper injection cavity seat above. An injection pipe connected to the injection branch pipe and the injection cavity is installed on the upper injection cavity seat, and several hot circulation pipes for installing hot circulation pipelines are also installed on the upper injection cavity seat.

[0007] As a further improvement of this utility model, the injection molded part body is installed in the injection molded part receiving cavity on the injection molded part mounting plate, and the injection main pipe can pass through the upper cover plate and continue to extend to its top outer side.

[0008] As a further improvement of this utility model, a side locking bracket is installed between the injection molding part mounting plate, the upper mold base, the lower template and the lower support plate.

[0009] As a further improvement of this utility model, the upper cover plate, the injection molding part mounting plate, the upper mold base and the lower mold plate are guided and installed together by a number of first guide pillars; the upper mold base and the lower mold plate are guided and installed together by a number of second guide pillars; and the upper mold base, the lower mold plate and the lower support plate are guided and installed together by a number of third guide pillars.

[0010] As a further improvement of this utility model, a number of upper mold mounting slots for mounting upper injection cavity seats are provided at the bottom of the upper mold base, a number of lower mold mounting slots for mounting injection support seats are provided at the top of the lower mold plate, and a lower mold through hole for mounting lower injection protrusion seats is provided on the lower mold plate at the bottom of the lower mold mounting slot.

[0013] As a further improvement of this utility model, sealing rings are installed at the connection points between the upper injection cavity seat, the injection support seat, and the lower injection protrusion seat.

[0014] By means of the above solution, this utility model has at least the following advantages: The upper injection-molded concave cavity seat, the injection-molded support seat, and the lower injection-molded protrusion seat of this utility model form a special cavity with a hand handle ring, realizing the integral molding of the hand handle ring and the dish body.

[0015] This invention features two sets of heat circulation pipes connected to a heat source and a cold source, respectively. In conjunction with the heat circulation pipes surrounding the cavity, the temperature fluctuation in the cavity area can be controlled, reducing shrinkage cavities and deformation.
